To activate the new parameters, either reboot your computer - or - unload and reload the driver. - The syntax of the driver parameters is: - - modprobe sk98lin parameter=value1[,value2[,value3...]] - - where value1 refers to the first adapter, value2 to the second etc. - -NOTE: All parameters are case sensitive. Write them exactly as shown - below. - -Example: -Suppose you have two adapters. You want to set auto-negotiation -on the first adapter to ON and on the second adapter to OFF. -You also want to set DuplexCapabilities on the first adapter -to FULL, and on the second adapter to HALF. -Then, you must enter: - - modprobe sk98lin AutoNeg_A=On,Off DupCap_A=Full,Half - -NOTE: The number of adapters that can be configured this way is - limited in the driver (file skge.c, constant SK_MAX_CARD_PARAM). - The current limit is 16. If you happen to install - more adapters, adjust this and recompile. - - -4.1 Per-Port Parameters ------------------------- - -These settings are available for each port on the adapter. -In the following description, '?' stands for the port for -which you set the parameter (A or B). - -Speed ------ -Parameter: Speed_? -Values: 10, 100, 1000, Auto -Default: Auto - -This parameter is used to set the speed capabilities. It is only valid -for the SK-98xx V2.0 copper adapters. -Usually, the speed is negotiated between the two ports during link -establishment. If this fails, a port can be forced to a specific setting -with this parameter. - -Auto-Negotiation ----------------- -Parameter: AutoNeg_? -Values: On, Off, Sense -Default: On - -The "Sense"-mode automatically detects whether the link partner supports -auto-negotiation or not. - -Duplex Capabilities -------------------- -Parameter: DupCap_? -Values: Half, Full, Both -Default: Both - -This parameters is only relevant if auto-negotiation for this port is -not set to "Sense". If auto-negotiation is set to "On", all three values -are possible. If it is set to "Off", only "Full" and "Half" are allowed. -This parameter is useful if your link partner does not support all -possible combinations. - -Flow Control ------------- -Parameter: FlowCtrl_? -Values: Sym, SymOrRem, LocSend, None -Default: SymOrRem - -This parameter can be used to set the flow control capabilities the -port reports during auto-negotiation. It can be set for each port -individually. -Possible modes: - -- Sym = Symmetric: both link partners are allowed to send - PAUSE frames - -- SymOrRem = SymmetricOrRemote: both or only remote partner - are allowed to send PAUSE frames - -- LocSend = LocalSend: only local link partner is allowed - to send PAUSE frames - -- None = no link partner is allowed to send PAUSE frames - -NOTE: This parameter is ignored if auto-negotiation is set to "Off". - -Role in Master-Slave-Negotiation (1000Base-T only) --------------------------------------------------- -Parameter: Role_? -Values: Auto, Master, Slave -Default: Auto - -This parameter is only valid for the SK-9821 and SK-9822 adapters. -For two 1000Base-T ports to communicate, one must take the role of the -master (providing timing information), while the other must be the -slave. Usually, this is negotiated between the two ports during link -establishment. If this fails, a port can be forced to a specific setting -with this parameter. - - -4.2 Adapter Parameters ------------------------ - -Connection Type (SK-98xx V2.0 copper adapters only) ---------------- -Parameter: ConType -Values: Auto, 100FD, 100HD, 10FD, 10HD -Default: Auto - -The parameter 'ConType' is a combination of all five per-port parameters -within one single parameter. This simplifies the configuration of both ports -of an adapter card! The different values of this variable reflect the most -meaningful combinations of port parameters. - -The following table shows the values of 'ConType' and the corresponding -combinations of the per-port parameters: - - ConType | DupCap AutoNeg FlowCtrl Role Speed - ----------+------------------------------------------------------ - Auto | Both On SymOrRem Auto Auto - 100FD | Full Off None Auto (ignored) 100 - 100HD | Half Off None Auto (ignored) 100 - 10FD | Full Off None Auto (ignored) 10 - 10HD | Half Off None Auto (ignored) 10 - -Stating any other port parameter together with this 'ConType' variable -will result in a merged configuration of those settings. This due to -the fact, that the per-port parameters (e.g. Speed_? ) have a higher -priority than the combined variable 'ConType'. - -NOTE: This parameter is always used on both ports of the adapter card. - -Interrupt Moderation --------------------- -Parameter: Moderation -Values: None, Static, Dynamic -Default: None - -Interrupt moderation is employed to limit the maximum number of interrupts -the driver has to serve. That is, one or more interrupts (which indicate any -transmit or receive packet to be processed) are queued until the driver -processes them. When queued interrupts are to be served, is determined by the -'IntsPerSec' parameter, which is explained later below. - -Possible modes: - - -- None - No interrupt moderation is applied on the adapter card. - Therefore, each transmit or receive interrupt is served immediately - as soon as it appears on the interrupt line of the adapter card. - - -- Static - Interrupt moderation is applied on the adapter card. - All transmit and receive interrupts are queued until a complete - moderation interval ends. If such a moderation interval ends, all - queued interrupts are processed in one big bunch without any delay. - The term 'static' reflects the fact, that interrupt moderation is - always enabled, regardless how much network load is currently - passing via a particular interface. In addition, the duration of - the moderation interval has a fixed length that never changes while - the driver is operational. - - -- Dynamic - Interrupt moderation might be applied on the adapter card, - depending on the load of the system. If the driver detects that the - system load is too high, the driver tries to shield the system against - too much network load by enabling interrupt moderation. If - at a later - time - the CPU utilization decreases again (or if the network load is - negligible) the interrupt moderation will automatically be disabled. - -Interrupt moderation should be used when the driver has to handle one or more -interfaces with a high network load, which - as a consequence - leads also to a -high CPU utilization. When moderation is applied in such high network load -situations, CPU load might be reduced by 20-30%. - -NOTE: The drawback of using interrupt moderation is an increase of the round- -trip-time (RTT), due to the queueing and serving of interrupts at dedicated -moderation times. - -Interrupts per second ---------------------- -Parameter: IntsPerSec -Values: 30...40000 (interrupts per second) -Default: 2000 - -This parameter is only used if either static or dynamic interrupt moderation -is used on a network adapter card. Using this parameter if no moderation is -applied will lead to no action performed. - -This parameter determines the length of any interrupt moderation interval. -Assuming that static interrupt moderation is to be used, an 'IntsPerSec' -parameter value of 2000 will lead to an interrupt moderation interval of -500 microseconds. - -NOTE: The duration of the moderation interval is to be chosen with care. -At first glance, selecting a very long duration (e.g. only 100 interrupts per -second) seems to be meaningful, but the increase of packet-processing delay -is tremendous. On the other hand, selecting a very short moderation time might -compensate the use of any moderation being applied. - - -Preferred Port --------------- -Parameter: PrefPort -Values: A, B -Default: A - -This is used to force the preferred port to A or B (on dual-port network -adapters). The preferred port is the one that is used if both are detected -as fully functional. - -RLMT Mode (Redundant Link Management Technology) ------------------------------------------------- -Parameter: RlmtMode -Values: CheckLinkState,CheckLocalPort, CheckSeg, DualNet -Default: CheckLinkState - -RLMT monitors the status of the port. If the link of the active port -fails, RLMT switches immediately to the standby link. The virtual link is -maintained as long as at least one 'physical' link is up. - -Possible modes: - - -- CheckLinkState - Check link state only: RLMT uses the link state - reported by the adapter hardware for each individual port to - determine whether a port can be used for all network traffic or - not. - - -- CheckLocalPort - In this mode, RLMT monitors the network path - between the two ports of an adapter by regularly exchanging packets - between them. This mode requires a network configuration in which - the two ports are able to "see" each other (i.e. there must not be - any router between the ports). - - -- CheckSeg - Check local port and segmentation: This mode supports the - same functions as the CheckLocalPort mode and additionally checks - network segmentation between the ports. Therefore, this mode is only - to be used if Gigabit Ethernet switches are installed on the network - that have been configured to use the Spanning Tree protocol. - - -- DualNet - In this mode, ports A and B are used as separate devices. - If you have a dual port adapter, port A will be configured as eth0 - and port B as eth1. Both ports can be used independently with - distinct IP addresses. The preferred port setting is not used. - RLMT is turned off. - -NOTE: RLMT modes CLP and CLPSS are designed to operate in configurations - where a network path between the ports on one adapter exists. - Moreover, they are not designed to work where adapters are connected - back-to-back. -*** - - -5 Large Frame Support -====================== - -The driver supports large frames (also called jumbo frames). Using large -frames can result in an improved throughput if transferring large amounts -of data. -To enable large frames, set the MTU (maximum transfer unit) of the -interface to the desired value (up to 9000), execute the following -command: - ifconfig eth0 mtu 9000 -This will only work if you have two adapters connected back-to-back -or if you use a switch that supports large frames. When using a switch, -it should be configured to allow large frames and auto-negotiation should -be set to OFF. The setting must be configured on all adapters that can be -reached by the large frames. If one adapter is not set to receive large -frames, it will simply drop them. - -You can switch back to the standard ethernet frame size by executing the -following command: - ifconfig eth0 mtu 1500 - -To permanently configure this setting, add a script with the 'ifconfig' -line to the system startup sequence (named something like "S99sk98lin" -in /etc/rc.d/rc2.d). -*** - - -6 VLAN and Link Aggregation Support (IEEE 802.1, 802.1q, 802.3ad) -================================================================== - -The Marvell Yukon/SysKonnect Linux drivers are able to support VLAN and -Link Aggregation according to IEEE standards 802.1, 802.1q, and 802.3ad. -These features are only available after installation of open source -modules available on the Internet: -For VLAN go to: http://www.candelatech.com/~greear/vlan.html -For Link Aggregation go to: http://www.st.rim.or.jp/~yumo - -NOTE: SysKonnect GmbH does not offer any support for these open source - modules and does not take the responsibility for any kind of - failures or problems arising in connection with these modules. - -NOTE: Configuring Link Aggregation on a SysKonnect dual link adapter may - cause problems when unloading the driver. - - -7 Troubleshooting -================== - -If any problems occur during the installation process, check the -following list: - - -Problem: The SK-98xx adapter cannot be found by the driver. -Solution: In /proc/pci search for the following entry: - 'Ethernet controller: SysKonnect SK-98xx ...' - If this entry exists, the SK-98xx or SK-98xx V2.0 adapter has - been found by the system and should be operational. - If this entry does not exist or if the file '/proc/pci' is not - found, there may be a hardware problem or the PCI support may - not be enabled in your kernel. - The adapter can be checked using the diagnostics program which - is available on the SysKonnect web site: - www.syskonnect.com - - Some COMPAQ machines have problems dealing with PCI under Linux. - This problem is described in the 'PCI howto' document - (included in some distributions or available from the - web, e.g. at 'www.linux.org'). - - -Problem: Programs such as 'ifconfig' or 'route' cannot be found or the - error message 'Operation not permitted' is displayed. -Reason: You are not logged in as user 'root'. -Solution: Logout and login as 'root' or change to 'root' via 'su'. - - -Problem: Upon use of the command 'ping

The spidernet is a gigabit +ethernet device built into the Toshiba southbridge commonly used +in the SONY Playstation 3 and the IBM QS20 Cell blade. + +The Structure of the RX Ring. +============================= +The receive (RX) ring is a circular linked list of RX descriptors, +together with three pointers into the ring that are used to manage its +contents. + +The elements of the ring are called "descriptors" or "descrs"; they +describe the received data. This includes a pointer to a buffer +containing the received data, the buffer size, and various status bits. + +There are three primary states that a descriptor can be in: "empty", +"full" and "not-in-use". An "empty" or "ready" descriptor is ready +to receive data from the hardware. A "full" descriptor has data in it, +and is waiting to be emptied and processed by the OS. A "not-in-use" +descriptor is neither empty or full; it is simply not ready. It may +not even have a data buffer in it, or is otherwise unusable. + +During normal operation, on device startup, the OS (specifically, the +spidernet device driver) allocates a set of RX descriptors and RX +buffers. These are all marked "empty", ready to receive data. This +ring is handed off to the hardware, which sequentially fills in the +buffers, and marks them "full". The OS follows up, taking the full +buffers, processing them, and re-marking them empty. + +This filling and emptying is managed by three pointers, the "head" +and "tail" pointers, managed by the OS, and a hardware current +descriptor pointer (GDACTDPA). The GDACTDPA points at the descr +currently being filled. When this descr is filled, the hardware +marks it full, and advances the GDACTDPA by one. Thus, when there is +flowing RX traffic, every descr behind it should be marked "full", +and everything in front of it should be "empty". If the hardware +discovers that the current descr is not empty, it will signal an +interrupt, and halt processing. + +The tail pointer tails or trails the hardware pointer. When the +hardware is ahead, the tail pointer will be pointing at a "full" +descr. The OS will process this descr, and then mark it "not-in-use", +and advance the tail pointer. Thus, when there is flowing RX traffic, +all of the descrs in front of the tail pointer should be "full", and +all of those behind it should be "not-in-use". When RX traffic is not +flowing, then the tail pointer can catch up to the hardware pointer. +The OS will then note that the current tail is "empty", and halt +processing. + +The head pointer (somewhat mis-named) follows after the tail pointer. +When traffic is flowing, then the head pointer will be pointing at +a "not-in-use" descr. The OS will perform various housekeeping duties +on this descr. This includes allocating a new data buffer and +dma-mapping it so as to make it visible to the hardware. The OS will +then mark the descr as "empty", ready to receive data. Thus, when there +is flowing RX traffic, everything in front of the head pointer should +be "not-in-use", and everything behind it should be "empty". If no +RX traffic is flowing, then the head pointer can catch up to the tail +pointer, at which point the OS will notice that the head descr is +"empty", and it will halt processing. + +Thus, in an idle system, the GDACTDPA, tail and head pointers will +all be pointing at the same descr, which should be "empty". All of the +other descrs in the ring should be "empty" as well. + +The show_rx_chain() routine will print out the the locations of the +GDACTDPA, tail and head pointers. It will also summarize the contents +of the ring, starting at the tail pointer, and listing the status +of the descrs that follow. + +A typical example of the output, for a nearly idle system, might be + +net eth1: Total number of descrs=256 +net eth1: Chain tail located at descr=20 +net eth1: Chain head is at 20 +net eth1: HW curr desc (GDACTDPA) is at 21 +net eth1: Have 1 descrs with stat=x40800101 +net eth1: HW next desc (GDACNEXTDA) is at 22 +net eth1: Last 255 descrs with stat=xa0800000 + +In the above, the hardware has filled in one descr, number 20. Both +head and tail are pointing at 20, because it has not yet been emptied. +Meanwhile, hw is pointing at 21, which is free. + +The "Have nnn decrs" refers to the descr starting at the tail: in this +case, nnn=1 descr, starting at descr 20. The "Last nnn descrs" refers +to all of the rest of the descrs, from the last status change. The "nnn" +is a count of how many descrs have exactly the same status. + +The status x4... corresponds to "full" and status xa... corresponds +to "empty". The actual value printed is RXCOMST_A. + +In the device driver source code, a different set of names are +used for these same concepts, so that + +"empty" == SPIDER_NET_DESCR_CARDOWNED == 0xa +"full" == SPIDER_NET_DESCR_FRAME_END == 0x4 +"not in use" == SPIDER_NET_DESCR_NOT_IN_USE == 0xf + + +The RX RAM full bug/feature +=========================== + +As long as the OS can empty out the RX buffers at a rate faster than +the hardware can fill them, there is no problem. If, for some reason, +the OS fails to empty the RX ring fast enough, the hardware GDACTDPA +pointer will catch up to the head, notice the not-empty condition, +ad stop. However, RX packets may still continue arriving on the wire. +The spidernet chip can save some limited number of these in local RAM. +When this local ram fills up, the spider chip will issue an interrupt +indicating this (GHIINT0STS will show ERRINT, and the GRMFLLINT bit +will be set in GHIINT1STS). When the RX ram full condition occurs, +a certain bug/feature is triggered that has to be specially handled. +This section describes the special handling for this condition. + +When the OS finally has a chance to run, it will empty out the RX ring. +In particular, it will clear the descriptor on which the hardware had +stopped. However, once the hardware has decided that a certain +descriptor is invalid, it will not restart at that descriptor; instead +it will restart at the next descr. This potentially will lead to a +deadlock condition, as the tail pointer will be pointing at this descr, +which, from the OS point of view, is empty; the OS will be waiting for +this descr to be filled. However, the hardware has skipped this descr, +and is filling the next descrs. Since the OS doesn't see this, there +is a potential deadlock, with the OS waiting for one descr to fill, +while the hardware is waiting for a different set of descrs to become +empty. + +A call to show_rx_chain() at this point indicates the nature of the +problem. A typical print when the network is hung shows the following: + +net eth1: Spider RX RAM full, incoming packets might be discarded! +net eth1: Total number of descrs=256 +net eth1: Chain tail located at descr=255 +net eth1: Chain head is at 255 +net eth1: HW curr desc (GDACTDPA) is at 0 +net eth1: Have 1 descrs with stat=xa0800000 +net eth1: HW next desc (GDACNEXTDA) is at 1 +net eth1: Have 127 descrs with stat=x40800101 +net eth1: Have 1 descrs with stat=x40800001 +net eth1: Have 126 descrs with stat=x40800101 +net eth1: Last 1 descrs with stat=xa0800000 + +Both the tail and head pointers are pointing at descr 255, which is +marked xa... which is "empty". Thus, from the OS point of view, there +is nothing to be done. In particular, there is the implicit assumption +that everything in front of the "empty" descr must surely also be empty, +as explained in the last section. The OS is waiting for descr 255 to +become non-empty, which, in this case, will never happen. + +The HW pointer is at descr 0. This descr is marked 0x4.. or "full". +Since its already full, the hardware can do nothing more, and thus has +halted processing. Notice that descrs 0 through 254 are all marked +"full", while descr 254 and 255 are empty. (The "Last 1 descrs" is +descr 254, since tail was at 255.) Thus, the system is deadlocked, +and there can be no forward progress; the OS thinks there's nothing +to do, and the hardware has nowhere to put incoming data. + +This bug/feature is worked around with the spider_net_resync_head_ptr() +routine. When the driver receives RX interrupts, but an examination +of the RX chain seems to show it is empty, then it is probable that +the hardware has skipped a descr or two (sometimes dozens under heavy +network conditions). The spider_net_resync_head_ptr() subroutine will +search the ring for the next full descr, and the driver will resume +operations there. Since this will leave "holes" in the ring, there +is also a spider_net_resync_tail_ptr() that will skip over such holes. + +As of this writing, the spider_net_resync() strategy seems to work very +well, even under heavy network loads. + + +The TX ring +=========== +The TX ring uses a low-watermark interrupt scheme to make sure that +the TX queue is appropriately serviced for large packet sizes. + +For packet sizes greater than about 1KBytes, the kernel can fill +the TX ring quicker than the device can drain it. Once the ring +is full, the netdev is stopped. When there is room in the ring, +the netdev needs to be reawakened, so that more TX packets are placed +in the ring. The hardware can empty the ring about four times per jiffy, +so its not appropriate to wait for the poll routine to refill, since +the poll routine runs only once per jiffy. The low-watermark mechanism +marks a descr about 1/4th of the way from the bottom of the queue, so +that an interrupt is generated when the descr is processed. This +interrupt wakes up the netdev, which can then refill the queue. +For large packets, this mechanism generates a relatively small number +of interrupts, about 1K/sec. For smaller packets, this will drop to zero +interrupts, as the hardware can empty the queue faster than the kernel +can fill it. + + + ======= END OF DOCUMENT ======== + diff --git a/Documentation/power_supply_class.txt b/Documentation/power_supply_class.txt new file mode 100644 index 000000000000..9758cf433c06 --- /dev/null +++ b/Documentation/power_supply_class.txt @@ -0,0 +1,167 @@ +Linux power supply class +======================== + +Synopsis +~~~~~~~~ +Power supply class used to represent battery, UPS, AC or DC power supply +properties to user-space. + +It defines core set of attributes, which should be applicable to (almost) +every power supply out there. Attributes are available via sysfs and uevent +interfaces. + +Each attribute has well defined meaning, up to unit of measure used. While +the attributes provided are believed to be universally applicable to any +power supply, specific monitoring hardware may not be able to provide them +all, so any of them may be skipped. + +Power supply class is extensible, and allows to define drivers own attributes. +The core attribute set is subject to the standard Linux evolution (i.e. +if it will be found that some attribute is applicable to many power supply +types or their drivers, it can be added to the core set). + +It also integrates with LED framework, for the purpose of providing +typically expected feedback of battery charging/fully charged status and +AC/USB power supply online status. (Note that specific details of the +indication (including whether to use it at all) are fully controllable by +user and/or specific machine defaults, per design principles of LED +framework). + + +Attributes/properties +~~~~~~~~~~~~~~~~~~~~~ +Power supply class has predefined set of attributes, this eliminates code +duplication across drivers. Power supply class insist on reusing its +predefined attributes *and* their units. + +So, userspace gets predictable set of attributes and their units for any +kind of power supply, and can process/present them to a user in consistent +manner.

Maximal/minimal means values of voltages +when battery considered "full"/"empty" at normal conditions.

For example: if there are 2 tasks +running then it runs each at 50% physical power - totally in parallel. + +On real hardware, we can run only a single task at once, so while that +one task runs, the other tasks that are waiting for the CPU are at a +disadvantage - the current task gets an unfair amount of CPU time. In +CFS this fairness imbalance is expressed and tracked via the per-task +p->wait_runtime (nanosec-unit) value. "wait_runtime" is the amount of +time the task should now run on the CPU for it to become completely fair +and balanced. + +( small detail: on 'ideal' hardware, the p->wait_runtime value would + always be zero - no task would ever get 'out of balance' from the + 'ideal' share of CPU time. ) + +CFS's task picking logic is based on this p->wait_runtime value and it +is thus very simple: it always tries to run the task with the largest +p->wait_runtime value. In other words, CFS tries to run the task with +the 'gravest need' for more CPU time. So CFS always tries to split up +CPU time between runnable tasks as close to 'ideal multitasking +hardware' as possible. + +Most of the rest of CFS's design just falls out of this really simple +concept, with a few add-on embellishments like nice levels, +multiprocessing and various algorithm variants to recognize sleepers. + +In practice it works like this: the system runs a task a bit, and when +the task schedules (or a scheduler tick happens) the task's CPU usage is +'accounted for': the (small) time it just spent using the physical CPU +is deducted from p->wait_runtime. [minus the 'fair share' it would have +gotten anyway]. Once p->wait_runtime gets low enough so that another +task becomes the 'leftmost task' of the time-ordered rbtree it maintains +(plus a small amount of 'granularity' distance relative to the leftmost +task so that we do not over-schedule tasks and trash the cache) then the +new leftmost task is picked and the current task is preempted. + +The rq->fair_clock value tracks the 'CPU time a runnable task would have +fairly gotten, had it been runnable during that time'. So by using +rq->fair_clock values we can accurately timestamp and measure the +'expected CPU time' a task should have gotten. All runnable tasks are +sorted in the rbtree by the "rq->fair_clock - p->wait_runtime" key, and +CFS picks the 'leftmost' task and sticks to it. As the system progresses +forwards, newly woken tasks are put into the tree more and more to the +right - slowly but surely giving a chance for every task to become the +'leftmost task' and thus get on the CPU within a deterministic amount of +time. + +Some implementation details: + + - the introduction of Scheduling Classes: an extensible hierarchy of + scheduler modules. These modules encapsulate scheduling policy + details and are handled by the scheduler core without the core + code assuming about them too much. + + - sched_fair.c implements the 'CFS desktop scheduler': it is a + replacement for the vanilla scheduler's SCHED_OTHER interactivity + code. + + I'd like to give credit to Con Kolivas for the general approach here: + he has proven via RSDL/SD that 'fair scheduling' is possible and that + it results in better desktop scheduling. Kudos Con! + + The CFS patch uses a completely different approach and implementation + from RSDL/SD. My goal was to make CFS's interactivity quality exceed + that of RSDL/SD, which is a high standard to meet :-) Testing + feedback is welcome to decide this one way or another. [ and, in any + case, all of SD's logic could be added via a kernel/sched_sd.c module + as well, if Con is interested in such an approach. ] + + CFS's design is quite radical: it does not use runqueues, it uses a + time-ordered rbtree to build a 'timeline' of future task execution, + and thus has no 'array switch' artifacts (by which both the vanilla + scheduler and RSDL/SD are affected). + + CFS uses nanosecond granularity accounting and does not rely on any + jiffies or other HZ detail. Thus the CFS scheduler has no notion of + 'timeslices' and has no heuristics whatsoever. There is only one + central tunable: + + /proc/sys/kernel/sched_granularity_ns + + which can be used to tune the scheduler from 'desktop' (low + latencies) to 'server' (good batching) workloads. It defaults to a + setting suitable for desktop workloads. SCHED_BATCH is handled by the + CFS scheduler module too. + + Due to its design, the CFS scheduler is not prone to any of the + 'attacks' that exist today against the heuristics of the stock + scheduler: fiftyp.c, thud.c, chew.c, ring-test.c, massive_intr.c all + work fine and do not impact interactivity and produce the expected + behavior. + + the CFS scheduler has a much stronger handling of nice levels and + SCHED_BATCH: both types of workloads should be isolated much more + agressively than under the vanilla scheduler. + + ( another detail: due to nanosec accounting and timeline sorting, + sched_yield() support is very simple under CFS, and in fact under + CFS sched_yield() behaves much better than under any other + scheduler i have tested so far. ) + + - sched_rt.c implements SCHED_FIFO and SCHED_RR semantics, in a simpler + way than the vanilla scheduler does. It uses 100 runqueues (for all + 100 RT priority levels, instead of 140 in the vanilla scheduler) + and it needs no expired array. + + - reworked/sanitized SMP load-balancing: the runqueue-walking + assumptions are gone from the load-balancing code now, and + iterators of the scheduling modules are used.

I use busy wait instead of timer wait in STEN_LOW,DTEN_LOW - thus driver causes CPU overhead and is very slow - 2. could not find a way to stop the drive, when it is - in data read mode, therefore I had to set - msf.end.min/sec/frame to 0:0:1 (in azt_poll); so only one - frame can be read in sequence, this is also the reason for - 3. getting 'timeout in state 4' messages, but nevertheless - it works - W.Zimmermann, Oct. 31, 1994 - V0.1 Version is ALPHA, problems #2 and #3 resolved. - W.Zimmermann, Nov. 3, 1994 - V0.2 Modification to some comments, debugging aids for partial test - with Borland C under DOS eliminated. Timer interrupt wait - STEN_LOW_WAIT additionally to busy wait for STEN_LOW implemented; - use it only for the 'slow' commands (ACMD_GET_Q_CHANNEL, ACMD_ - SEEK_TO_LEAD_IN), all other commands are so 'fast', that busy - waiting seems better to me than interrupt rescheduling. - Besides that, when used in the wrong place, STEN_LOW_WAIT causes - kernel panic. - In function aztPlay command ACMD_PLAY_AUDIO added, should make - audio functions work. The Aztech drive needs different commands - to read data tracks and play audio tracks. - W.Zimmermann, Nov. 8, 1994 - V0.3 Recognition of missing drive during boot up improved (speeded up). - W.Zimmermann, Nov. 13, 1994 - V0.35 Rewrote the control mechanism in azt_poll (formerly mcd_poll) - including removal of all 'goto' commands. :-); - J. Nardone, Nov. 14, 1994 - V0.4 Renamed variables and constants to 'azt' instead of 'mcd'; had - to make some "compatibility" defines in azt.h; please note, - that the source file was renamed to azt.c, the include file to - azt.h - Speeded up drive recognition during init (will be a little bit - slower than before if no drive is installed!); suggested by - Robby Schirmer. - read_count declared volatile and set to AZT_BUF_SIZ to make - drive faster (now 300kB/sec, was 60kB/sec before, measured - by 'time dd if=/dev/cdrom of=/dev/null bs=2048 count=4096'; - different AZT_BUF_SIZes were test, above 16 no further im- - provement seems to be possible; suggested by E.Moenkeberg. - W.Zimmermann, Nov. 18, 1994 - V0.42 Included getAztStatus command in GetQChannelInfo() to allow - reading Q-channel info on audio disks, if drive is stopped, - and some other bug fixes in the audio stuff, suggested by - Robby Schirmer. - Added more ioctls (reading data in mode 1 and mode 2). - Completely removed the old azt_poll() routine. - Detection of ORCHID CDS-3110 in aztcd_init implemented. - Additional debugging aids (see the readme file). - W.Zimmermann, Dec. 9, 1994 - V0.50 Autodetection of drives implemented. - W.Zimmermann, Dec. 12, 1994 - V0.52 Prepared for including in the standard kernel, renamed most - variables to contain 'azt', included autoconf.h - W.Zimmermann, Dec. 16, 1994 - V0.6 Version for being included in the standard Linux kernel. - Renamed source and header file to aztcd.c and aztcd.h - W.Zimmermann, Dec. 24, 1994 - V0.7 Changed VERIFY_READ to VERIFY_WRITE in aztcd_ioctl, case - CDROMREADMODE1 and CDROMREADMODE2; bug fix in the ioctl, - which causes kernel crashes when playing audio, changed - include-files (config.h instead of autoconf.h, removed - delay.h) - W.Zimmermann, Jan. 8, 1995 - V0.72 Some more modifications for adaption to the standard kernel. - W.Zimmermann, Jan. 16, 1995 - V0.80 aztcd is now part of the standard kernel since version 1.1.83. - Modified the SET_TIMER and CLEAR_TIMER macros to comply with - the new timer scheme. - W.Zimmermann, Jan. 21, 1995 - V0.90 Included CDROMVOLCTRL, but with my Aztech drive I can only turn - the channels on and off. If it works better with your drive, - please mail me. Also implemented ACMD_CLOSE for CDROMSTART. - W.Zimmermann, Jan. 24, 1995 - V1.00 Implemented close and lock tray commands. Patches supplied by - Frank Racis - Added support for loadable MODULEs, so aztcd can now also be - loaded by insmod and removed by rmmod during run time - Werner Zimmermann, Mar. 24, 95 - V1.10 Implemented soundcard configuration for Orchid CDS-3110 drives - connected to Soundwave32 cards. Release for LST 2.1. - (still experimental) - Werner Zimmermann, May 8, 95 - V1.20 Implemented limited support for DOSEMU0.60's cdrom.c. Now it works, but - sometimes DOSEMU may hang for 30 seconds or so. A fully functional ver- - sion needs an update of Dosemu0.60's cdrom.c, which will come with the - next revision of Dosemu. - Also Soundwave32 support now works. - Werner Zimmermann, May 22, 95 - V1.30 Auto-eject feature. Inspired by Franc Racis (racis@psu.edu) - Werner Zimmermann, July 4, 95 - V1.40 Started multisession support. Implementation copied from mcdx.c - by Heiko Schlittermann. Not tested yet. - Werner Zimmermann, July 15, 95 - V1.50 Implementation of ioctl CDROMRESET, continued multisession, began - XA, but still untested. Heavy modifications to drive status de- - tection. - Werner Zimmermann, July 25, 95 - V1.60 XA support now should work. Speeded up drive recognition in cases, - where no drive is installed. - Werner Zimmermann, August 8, 1995 - V1.70 Multisession support now is completed, but there is still not - enough testing done. If you can test it, please contact me. For - details please read Documentation/cdrom/aztcd - Werner Zimmermann, August 19, 1995 - V1.80 Modification to suit the new kernel boot procedure introduced - with kernel 1.3.33.

Waiting for documentation... - 22 feb 1995: 0.1a first reasonably safe polling driver. - Two major bugs, one in read_sector and one in - do_cm206_request, happened to cancel! - 25 feb 1995: 0.2a first reasonable interrupt driven version of above. - uart writes are still done in polling mode. - 25 feb 1995: 0.21a writes also in interrupt mode, still some - small bugs to be found... Larger buffer. - 2 mrt 1995: 0.22 Bug found (cd-> nowhere, interrupt was called in - initialization), read_ahead of 16. Timeouts implemented. - unclear if they do something... - 7 mrt 1995: 0.23 Start of background read-ahead. - 18 mrt 1995: 0.24 Working background read-ahead. (still problems) - 26 mrt 1995: 0.25 Multi-session ioctl added (kernel v1.2). - Statistics implemented, though separate stats206.h. - Accessible through ioctl 0x1000 (just a number). - Hard to choose between v1.2 development and 1.1.75. - Bottom-half doesn't work with 1.2... - 0.25a: fixed... typo. Still problems... - 1 apr 1995: 0.26 Module support added. Most bugs found. Use kernel 1.2.n. - 5 apr 1995: 0.27 Auto-probe for the adapter card base address. - Auto-probe for the adaptor card irq line. - 7 apr 1995: 0.28 Added lilo setup support for base address and irq. - Use major number 32 (not in this source), officially - assigned to this driver. - 9 apr 1995: 0.29 Added very limited audio support. Toc_header, stop, pause, - resume, eject. Play_track ignores track info, because we can't - read a table-of-contents entry. Toc_entry is implemented - as a `placebo' function: always returns start of disc. - 3 may 1995: 0.30 Audio support completed. The get_toc_entry function - is implemented as a binary search. - 15 may 1995: 0.31 More work on audio stuff. Workman is not easy to - satisfy; changed binary search into linear search. - Auto-probe for base address somewhat relaxed. - 1 jun 1995: 0.32 Removed probe_irq_on/off for module version. - 10 jun 1995: 0.33 Workman still behaves funny, but you should be - able to eject and substitute another disc. - - An adaptation of 0.33 is included in linux-1.3.7 by Eberhard Moenkeberg - - 18 jul 1995: 0.34 Patch by Heiko Eissfeldt included, mainly considering - verify_area's in the ioctls. Some bugs introduced by - EM considering the base port and irq fixed. - - 18 dec 1995: 0.35 Add some code for error checking... no luck... - - We jump to reach our goal: version 1.0 in the next stable linux kernel. - - 19 mar 1996: 0.95 Different implementation of CDROM_GET_UPC, on - request of Thomas Quinot. - 25 mar 1996: 0.96 Interpretation of opening with O_WRONLY or O_RDWR: - open only for ioctl operation, e.g., for operation of - tray etc. - 4 apr 1996: 0.97 First implementation of layer between VFS and cdrom - driver, a generic interface. Much of the functionality - of cm206_open() and cm206_ioctl() is transferred to a - new file cdrom.c and its header ucdrom.h. - - Upgrade to Linux kernel 1.3.78. - - 11 apr 1996 0.98 Upgrade to Linux kernel 1.3.85 - More code moved to cdrom.c - - 0.99 Some more small changes to decrease number - of oopses at module load; - - 27 jul 1996 0.100 Many hours of debugging, kernel change from 1.2.13 - to 2.0.7 seems to have introduced some weird behavior - in (interruptible_)sleep_on(&cd->data): the process - seems to be woken without any explicit wake_up in my own - code. Patch to try 100x in case such untriggered wake_up's - occur. - - 28 jul 1996 0.101 Rewriting of the code that receives the command echo, - using a fifo to store echoed bytes. - - Branch from 0.99: - - 0.99.1.0 Update to kernel release 2.0.10 dev_t -> kdev_t - (emoenke) various typos found by others. extra - module-load oops protection. - - 0.99.1.1 Initialization constant cdrom_dops.speed - changed from float (2.0) to int (2); Cli()-sti() pair - around cm260_reset() in module initialization code. - - 0.99.1.2 Changes literally as proposed by Scott Snyder - for the 2.1 kernel line, which - have to do mainly with the poor minor support i had. The - major new concept is to change a cdrom driver's - operations struct from the capabilities struct. This - reflects the fact that there is one major for a driver, - whilst there can be many minors whith completely - different capabilities. - - 0.99.1.3 More changes for operations/info separation. - - 0.99.1.4 Added speed selection (someone had to do this - first). - - 23 jan 1997 0.99.1.5 MODULE_PARMS call added. - - 23 jan 1997 0.100.1.2--0.100.1.5 following similar lines as - 0.99.1.1--0.99.1.5. I get too many complaints about the - drive making read errors. What't wrong with the 2.0+ - kernel line? Why get i (and othe cm206 owners) weird - results? Why were things good in the good old 1.1--1.2 - era? Why don't i throw away the drive? - - 2 feb 1997 0.102 Added `volatile' to values in cm206_struct. Seems to - reduce many of the problems. Rewrote polling routines - to use fixed delays between polls. - 0.103 Changed printk behavior. - 0.104 Added a 0.100 -> 0.100.1.1 change - -11 feb 1997 0.105 Allow auto_probe during module load, disable - with module option "auto_probe=0". Moved some debugging - statements to lower priority. Implemented select_speed() - function. - -13 feb 1997 1.0 Final version for 2.0 kernel line. - - All following changes will be for the 2.1 kernel line. - -15 feb 1997 1.1 Keep up with kernel 2.1.26, merge in changes from - cdrom.c 0.100.1.1--1.0. Add some more MODULE_PARMS. - -14 sep 1997 1.2 Upgrade to Linux 2.1.55. Added blksize_size[], patch - sent by James Bottomley . - -21 dec 1997 1.4 Upgrade to Linux 2.1.72. - -24 jan 1998 Removed the cm206_disc_status() function, as it was now dead - code. The Uniform CDROM driver now provides this functionality. - -9 Nov. 1999 Make kernel-parameter implementation work with 2.3.x - Removed init_module & cleanup_module in favor of - module_init & module_exit. - Torben Mathiasen - * - * Parts of the code are based upon lmscd.c written by Kai Petzke, - * sbpcd.c written by Eberhard Moenkeberg, and mcd.c by Martin - * Harriss, but any off-the-shelf dynamic programming algorithm won't - * be able to find them. - * - * The cm206 drive interface and the cm260 adapter card seem to be - * sufficiently different from their cm205/cm250 counterparts - * in order to write a complete new driver. - * - * I call all routines connected to the Linux kernel something - * with `cm206' in it, as this stuff is too series-dependent. - * - * Currently, my limited knowledge is based on: - * - The Linux Kernel Hacker's guide, v. 0.5, by Michael K.

Speed is around 240 kb/s, as measured - with "time dd if=/dev/cdrom of=/dev/null \ - bs=2048 count=4096". - 24-6-95 v0.2 Reworked the #defines for the command codes - and the like, as well as the structure of - the hardware communication protocol, to - reflect the "official" documentation, kindly - supplied by C.K. Tan, Optics Storage Pte. Ltd. - Also tidied up the state machine somewhat. - 28-6-95 v0.3 Removed the ISP-16 interface code, as this - should go into its own driver. The driver now - has its own major nr. - Disk change detection now seems to work, too. - This version became part of the standard - kernel as of version 1.3.7 - 24-9-95 v0.4 Re-inserted ISP-16 interface code which I - copied from sjcd.c, with a few changes. - Updated README.optcd. Submitted for - inclusion in 1.3.21 - 29-9-95 v0.4a Fixed bug that prevented compilation as module - 25-10-95 v0.5 Started multisession code. Implementation - copied from Werner Zimmermann, who copied it - from Heiko Schlittermann's mcdx. - 17-1-96 v0.6 Multisession works; some cleanup too. - 18-4-96 v0.7 Increased some timing constants; - thanks to Luke McFarlane. Also tidied up some - printk behaviour. ISP16 initialization - is now handled by a separate driver. - - 09-11-99 Make kernel-parameter implementation work with 2.3.x - Removed init_module & cleanup_module in favor of - module_init & module_exit. - Torben Mathiasen -*/ - -/* Includes */ - - -#include -#include -#include -#include - -#include -#include - -#include -#include "optcd.h" - -#include - -#define MAJOR_NR OPTICS_CDROM_MAJOR -#define QUEUE (opt_queue) -#define CURRENT elv_next_request(opt_queue) - - -/* Debug support */ - - -/* Don't forget to add new debug flags here. */ -#if DEBUG_DRIVE_IF | DEBUG_VFS | DEBUG_CONV | DEBUG_TOC | \ - DEBUG_BUFFERS | DEBUG_REQUEST | DEBUG_STATE | DEBUG_MULTIS -#define DEBUG(x) debug x -static void debug(int debug_this, const char* fmt, ...) -{ - char s[1024];

That gives the message - * "ResponseStatus timed out" (happens about 6 times here during - * a "ls -alR" of the YGGDRASIL LGX-Beta CD). Such a case is - * handled without data error, but it should get done better. - * - * 0.5 Free CPU during waits (again with help from Kai Makisara). - * Made it work together with the LILO/kernel setup standard. - * Included auto-probing code, as suggested by YGGDRASIL. - * Formal redesign to add DDI debugging. - * There are still flaws in IOCTL (workman with double speed drive). - * - * 1.0 Added support for all drive IDs (0...3, no longer only 0) - * and up to 4 drives on one controller. - * Added "#define MANY_SESSION" for "old" multi session CDs. - * - * 1.1 Do SpinUp for new drives, too. - * Revised for clean compile under "old" kernels (0.99pl9). - * - * 1.2 Found the "workman with double-speed drive" bug: use the driver's - * audio_state, not what the drive is reporting with ReadSubQ. - * - * 1.3 Minor cleanups. - * Refinements regarding Workman. - * - * 1.4 Read XA disks (PhotoCDs) with "old" drives, too (but only the first - * session - no chance to fully access a "multi-session" CD). - * This currently still is too slow (50 kB/sec) - but possibly - * the old drives won't do it faster. - * Implemented "door (un)lock" for new drives (still does not work - * as wanted - no lock possible after an unlock). - * Added some debugging printout for the UPC/EAN code - but my drives - * return only zeroes. Is there no UPC/EAN code written? - * - * 1.5 Laborate with UPC/EAN code (not better yet). - * Adapt to kernel 1.1.8 change (have to explicitly include - * now). - * - * 1.6 Trying to read audio frames as data. Impossible with the current - * drive firmware levels, as it seems. Awaiting any hint. ;-) - * Changed "door unlock": repeat it until success. - * Changed CDROMSTOP routine (stop somewhat "softer" so that Workman - * won't get confused). - * Added a third interface type: Sequoia S-1000, as used with the SPEA - * Media FX sound card. This interface (usable for Sony and Mitsumi - * drives, too) needs a special configuration setup and behaves like a - * LaserMate type after that. Still experimental - I do not have such - * an interface. - * Use the "variable BLOCK_SIZE" feature (2048). But it does only work - * if you give the mount option "block=2048". - * The media_check routine is currently disabled; now that it gets - * called as it should I fear it must get synchronized for not to - * disturb the normal driver's activity. - * - * 2.0 Version number bumped - two reasons: - * - reading audio tracks as data works now with CR-562 and CR-563. We - * currently do it by an IOCTL (yet has to get standardized), one frame - * at a time; that is pretty slow. But it works. - * - we are maintaining now up to 4 interfaces (each up to 4 drives): - * did it the easy way - a different MAJOR (25, 26, ...) and a different - * copy of the driver (sbpcd.c, sbpcd2.c, sbpcd3.c, sbpcd4.c - only - * distinguished by the value of SBPCD_ISSUE and the driver's name), - * and a common sbpcd.h file. - * Bettered the "ReadCapacity error" problem with old CR-52x drives (the - * drives sometimes need a manual "eject/insert" before work): just - * reset the drive and do again. Needs lots of resets here and sometimes - * that does not cure, so this can't be the solution. - * - * 2.1 Found bug with multisession CDs (accessing frame 16). - * "read audio" works now with address type CDROM_MSF, too. - * Bigger audio frame buffer: allows reading max. 4 frames at time; this - * gives a significant speedup, but reading more than one frame at once - * gives missing chunks at each single frame boundary. - * - * 2.2 Kernel interface cleanups: timers, init, setup, media check. - * - * 2.3 Let "door lock" and "eject" live together. - * Implemented "close tray" (done automatically during open). - * - * 2.4 Use different names for device registering. - * - * 2.5 Added "#if EJECT" code (default: enabled) to automatically eject - * the tray during last call to "sbpcd_release". - * Added "#if JUKEBOX" code (default: disabled) to automatically eject - * the tray during call to "sbpcd_open" if no disk is in. - * Turn on the CD volume of "compatible" sound cards, too; just define - * SOUND_BASE (in sbpcd.h) accordingly (default: disabled). - * - * 2.6 Nothing new. - * - * 2.7 Added CDROMEJECT_SW ioctl to set the "EJECT" behavior on the fly: - * 0 disables, 1 enables auto-ejecting. Useful to keep the tray in - * during shutdown. - * - * 2.8 Added first support (still BETA, I need feedback or a drive) for - * the Longshine LCS-7260 drives. They appear as double-speed drives - * using the "old" command scheme, extended by tray control and door - * lock functions. - * Found (and fixed preliminary) a flaw with some multisession CDs: we - * have to re-direct not only the accesses to frame 16 (the isofs - * routines drive it up to max. 100), but also those to the continuation - * (repetition) frames (as far as they exist - currently set fix as - * 16..20). - * Changed default of the "JUKEBOX" define. If you use this default, - * your tray will eject if you try to mount without a disk in. Next - * mount command will insert the tray - so, just fill in a disk. ;-) - * - * 2.9 Fulfilled the Longshine LCS-7260 support; with great help and - * experiments by Serge Robyns. - * First attempts to support the TEAC CD-55A drives; but still not - * usable yet. - * Implemented the CDROMMULTISESSION ioctl; this is an attempt to handle - * multi session CDs more "transparent" (redirection handling has to be - * done within the isofs routines, and only for the special purpose of - * obtaining the "right" volume descriptor; accesses to the raw device - * should not get redirected). - * - * 3.0 Just a "normal" increment, with some provisions to do it better. ;-) - * Introduced "#define READ_AUDIO" to specify the maximum number of - * audio frames to grab with one request. This defines a buffer size - * within kernel space; a value of 0 will reserve no such space and - * disable the CDROMREADAUDIO ioctl. A value of 75 enables the reading - * of a whole second with one command, but will use a buffer of more - * than 172 kB. - * Started CD200 support. Drive detection should work, but nothing - * more. - * - * 3.1 Working to support the CD200 and the Teac CD-55A drives. - * AT-BUS style device numbering no longer used: use SCSI style now. - * So, the first "found" device has MINOR 0, regardless of the - * jumpered drive ID. This implies modifications to the /dev/sbpcd* - * entries for some people, but will help the DAU (german TLA, english: - * "newbie", maybe ;-) to install his "first" system from a CD. - * - * 3.2 Still testing with CD200 and CD-55A drives. - * - * 3.3 Working with CD200 support. - * - * 3.4 Auto-probing stops if an address of 0 is seen (to be entered with - * the kernel command line). - * Made the driver "loadable". If used as a module, "audio copy" is - * disabled, and the internal read ahead data buffer has a reduced size - * of 4 kB; so, throughput may be reduced a little bit with slow CPUs. - * - * 3.5 Provisions to handle weird photoCDs which have an interrupted - * "formatting" immediately after the last frames of some files: simply - * never "read ahead" with MultiSession CDs. By this, CPU usage may be - * increased with those CDs, and there may be a loss in speed. - * Re-structured the messaging system. - * The "loadable" version no longer has a limited READ_AUDIO buffer - * size. - * Removed "MANY_SESSION" handling for "old" multi session CDs. - * Added "private" IOCTLs CDROMRESET and CDROMVOLREAD. - * Started again to support the TEAC CD-55A drives, now that I found - * the money for "my own" drive. ;-) - * The TEAC CD-55A support is fairly working now. - * I have measured that the drive "delivers" at 600 kB/sec (even with - * bigger requests than the drive's 64 kB buffer can satisfy), but - * the "real" rate does not exceed 520 kB/sec at the moment. - * Caused by the various changes to build in TEAC support, the timed - * loops are de-optimized at the moment (less throughput with CR-52x - * drives, and the TEAC will give speed only with SBP_BUFFER_FRAMES 64). - * - * 3.6 Fixed TEAC data read problems with SbPro interfaces. - * Initial size of the READ_AUDIO buffer is 0. Can get set to any size - * during runtime. - * - * 3.7 Introduced MAX_DRIVES for some poor interface cards (seen with TEAC - * drives) which allow only one drive (ID 0); this avoids repetitive - * detection under IDs 1..3. - * Elongated cmd_out_T response waiting; necessary for photo CDs with - * a lot of sessions. - * Bettered the sbpcd_open() behavior with TEAC drives. - * - * 3.8 Elongated max_latency for CR-56x drives. - * - * 3.9 Finally fixed the long-known SoundScape/SPEA/Sequoia S-1000 interface - * configuration bug. - * Now Corey, Heiko, Ken, Leo, Vadim/Eric & Werner are invited to copy - * the config_spea() routine into their drivers. ;-) - * - * 4.0 No "big step" - normal version increment. - * Adapted the benefits from 1.3.33. - * Fiddled with CDROMREADAUDIO flaws. - * Avoid ReadCapacity command with CD200 drives (the MKE 1.01 version - * seems not to support it). - * Fulfilled "read audio" for CD200 drives, with help of Pete Heist - * (heistp@rpi.edu). - * - * 4.1 Use loglevel KERN_INFO with printk(). - * Added support for "Vertos 100" drive ("ECS-AT") - it is very similar - * to the Longshine LCS-7260. Give feedback if you can - I never saw - * such a drive, and I have no specs. - * - * 4.2 Support for Teac 16-bit interface cards. Can't get auto-detected, - * so you have to jumper your card to 0x2C0. Still not 100% - come - * in contact if you can give qualified feedback. - * Use loglevel KERN_NOTICE with printk(). If you get annoyed by a - * flood of unwanted messages and the accompanied delay, try to read - * my documentation. Especially the Linux CDROM drivers have to do an - * important job for the newcomers, so the "distributed" version has - * to fit some special needs. Since generations, the flood of messages - * is user-configurable (even at runtime), but to get aware of this, one - * needs a special mental quality: the ability to read. - * - * 4.3 CD200F does not like to receive a command while the drive is - * reading the ToC; still trying to solve it. - * Removed some redundant verify_area calls (yes, Heiko Eissfeldt - * is visiting all the Linux CDROM drivers ;-). - * - * 4.4 Adapted one idea from tiensivu@pilot.msu.edu's "stripping-down" - * experiments: "KLOGD_PAUSE". - * Inhibited "play audio" attempts with data CDs. Provisions for a - * "data-safe" handling of "mixed" (data plus audio) Cds. - * - * 4.5 Meanwhile Gonzalo Tornaria (GTL) built a - * special end_request routine: we seem to have to take care for not - * to have two processes working at the request list. My understanding - * was and is that ll_rw_blk should not call do_sbpcd_request as long - * as there is still one call active (the first call will care for all - * outstanding I/Os, and if a second call happens, that is a bug in - * ll_rw_blk.c). - * "Check media change" without touching any drive. - * - * 4.6 Use a semaphore to synchronize multi-activity; elaborated by Rob - * Riggs .

With this interface, CDROMs can be - * accessed and standard audio CDs can be played back normally. - * - * This interface is (unfortunately) a polled interface. This is - * because most Sony interfaces are set up with DMA and interrupts - * disables. Some (like mine) do not even have the capability to - * handle interrupts or DMA. For this reason you will see a bit of - * the following: - * - * snap = jiffies; - * while (jiffies-snap < SONY_JIFFIES_TIMEOUT) - * { - * if (some_condition()) - * break; - * sony_sleep(); - * } - * if (some_condition not met) - * { - * return an_error; - * } - * - * This ugly hack waits for something to happen, sleeping a little - * between every try. (The conditional is written so that jiffies - * wrap-around is handled properly.) - * - * One thing about these drives: They talk in MSF (Minute Second Frame) format. - * There are 75 frames a second, 60 seconds a minute, and up to 75 minutes on a - * disk. The funny thing is that these are sent to the drive in BCD, but the - * interface wants to see them in decimal. A lot of conversion goes on. - * - * Copyright (C) 1993 Corey Minyard - * - * This program is free software; you can redistribute it and/or modify - * it under the terms of the GNU General Public License as published by - * the Free Software Foundation; either version 2 of the License, or - * (at your option) any later version. - * - * This program is distributed in the hope that it will be useful, - * but WITHOUT ANY WARRANTY; without even the implied warranty of - * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
