Benjamin Herrenschmidt b8c49ef6ae [PATCH] nvidiafb: Add flat panel dither support
nvidiafb didn't fully hook-up the code it borrowed from X for doing flat
panel dithering (this is useful for 6 bits panels).  This adds a driver
option to force it, and by default "reads" the current value from the chip
to get the firmware setting.  It significantly improves the quality of
images on the iMac G5 I have here (though the X driver doesn't yet "read"
the current value and defaults to 0, so you have to add Option "FBDither"
"true" to your X config file to get that, I'll try to fix X.org to "read"
the default unless specified asap).

Benjamin Herrenschmidt 85f1503aff [PATCH] nvidiafb: Fix mode setting & PPC support
This patch fixes nvifiafb mode setting code to be closer to what the X
driver does, which actually makes it work on the 5200FX I have access to.
It also fix the routine that gets the EDID from Open Firmware on PPC, it
was broken in various ways and would crash at boot.  Compared to the patch
I posted to linux-fbdev last week, this one just changes a printk to be
closer to the other ones in the driver.

Corey Minyard a9a2c44ff0 [PATCH] ipmi: add timer thread
We must poll for responses to commands when interrupts aren't in use.  The
default poll interval is based on using a kernel timer, which varies with HZ.
For character-based interfaces like KCS and SMIC though, that can be way too
slow (>15 minutes to flash a new firmware with KCS, >20 seconds to retrieve
the sensor list).

This creates a low-priority kernel thread to poll more often.  If the state
machine is idle, so is the kernel thread.  But if there's an active command,
it polls quite rapidly.  This decrease a firmware flash time from 15 minutes
to 1.5 minutes, and the sensor list time to 4.5 seconds, on a Dell PowerEdge
x8x system.

The timer-based polling remains, to ensure some amount of responsiveness even
under high user process CPU load.

Checking for a stopped timer at rmmod now uses atomics and del_timer_sync() to
ensure safe stoppage.

Corey Minyard c3e7e7916e [PATCH] ipmi: kcs error0 delay
BMCs can get into ERROR0 state while flashing new firmware, particularly while
the BMC is erasing the next flash block, which may take a just under 2 seconds
on a Dell PowerEdge 2800 (1.75 seconds typical), during which time the
single-threaded firmware may not be able to process new commands.  In
particular, clearing OBF may not take effect immediately.

We want it to delay in ERROR0 after clearing OBF a bit waiting for OBF to
actually be clear before proceeding.

This introduces a new return value from the LLDD's event loop,
SI_SM_CALL_WITH_TICK_DELAY.  This means the calling thread/timer should
schedule_timeout() at least 1 tick, rather than busy-wait.  This is a longer
delay than SI_SM_CALL_WITH_DELAY, which is typically a 250us busy-wait.

Corey Minyard 21dcd300b1 [PATCH] ipmi: bt restart reset fixes
The current BT retry/reset mechanism fails to succeed on a PowerEdge 1650,
when the controller is wedged with B2H_ATN asserted at XACTION_START.  If this
occurs, no further commands will ever succeed unless the state of the
controller is first cleared out.

Furthermore, the soft reset would only occur if the first command after insmod
was the one that timed out, not if a later command timed out.

This patch changes the retry/reset mechanism to be as follows:

Before retrying a command, clear the state of the BT controller such that the
flags represent ready for a new transaction.  This increases the chance of
success of the restarted transaction.

After 2 retries, issue a soft reset and retry one more time before giving up
and reporting back a failure.

Corey Minyard ea94027b92 [PATCH] ipmi: si start transaction hook
Some commands, on some system BMCs, don't respond at at all.  This is seen on
Dell PowerEdge x6xx and x7xx systems with IPMI 1.0 BT controllers when a "Get
SDR" command is issued, with a length field of 0x3A, which happens to be the
length of about SDR entries.  If another length is passed, this command
succeeds.

This patch adds general infrastructure for receiving commands before they're
passed down to the low-level drivers, such that they can be completed
immediately, or modified, prior to being sent to ->start_transaction().

Corey Minyard c4edff1c19 [PATCH] ipmi: various si cleanup
A number of small changes for the various system interface drivers,
consolidated from a number of patches from Matt Domsch.

Clear B2H_ATN and drain the BMC message buffer on command timeout.  This
prevents further commands from failing after a timeout.

Add bt_debug and smic_debug module parameters, expose them in sysfs.  This
lets you enable and disable debugging messages at runtime.

Unsigned jiffies math in ipmi_si_intf.c causes a too-large value to be passed
to ->event() after jiffies wrap-around.  The BT driver had caught this, but
didn't know how to fix it.  Now all calls to ->event() use a sane value for
time.

Increase timeout for commands handed to the BT driver from 2 seconds to 5
seconds.  This is necessary particularly when the previous command was a
"Clear SEL", as that command completes, yet the BMC isn't really ready to
handle another command yet.

Silence BT debugging messages which were being printed on the console.

Increase SMIC timeout form 1/10s to 2s.  This is needed on Dell PowerEdge 2650
and PowerEdge 750 with ERA/O cards to allow commands to complete without
timing out.

Adds kcs_debug module param, to match behavior of BT and SMIC.  This also
prevents messages from being sent to the console unless explicitly requested.

Corey Minyard 393d2cc354 [PATCH] ipmi: use refcount in message handler
This patch is rather large, but it really can't be done in smaller chunks
easily and I believe it is an important change.  This has been out and tested
for a while in the latest IPMI driver release.  There are no functional
changes, just changes as necessary to convert the locking over (and a few
minor style updates).

The IPMI driver uses read/write locks to ensure that things exist while they
are in use.  This is bad from a number of points of view.  This patch removes
the rwlocks and uses refcounts and RCU lists to manage what the locks did.

Nick Piggin f5b3db0017 [PATCH] as: cooperating processes
Introduce the notion of cooperating processes (those that submit requests
close to one another), and use these statistics to make better choices about
whether or not to do anticipatory waiting.

Help and analysis from Seetharami Seelam <seelam@cs.utep.edu>

Performance testing from Seelam:

I set up my system and executed a couple of tests that I used for OLS.  I
tested with AS, cooperative process patch merged in -mm tree (which I called
Nick, below) and the cooperative patch with modifications to as_update_iohist
(which I called Seelam).

I used a dual-processor (2.28GHz Pentium 4 Xeon) system, with 1 GB main memory
and 1 MB L2 cache, running Linux 2.6.9.  Only a single processor is used for
the experiments.  I used 7.2K RPM Maxtor 10GB drive configured with ext2 file
system.

Experiment 1 (ex1) consists of reading  one Linux source trees using

  find . -type f -exec cat '{}' ';' > /dev/null.

Experiment 2 (ex2) consists of reading two disjoint Linux source trees
using

  find . -type f -exec cat '{}' ';' > /dev/null.

Experiment 3 (ex3) consists of streaming read of a 2GB file in the background
and 1 instance of the chunk reads in Experiment 1.

Timings for reading the Linux source are shown below:

             AS                     Nick          Seelam
ex1:      0m25.813s               0m27.859s      0m27.640s
ex2:      1m11.468s               1m13.918s      1m5.869s
ex3:      81m44.352s             10m38.572s      6m47.994s

The difference between the numbers in Experiment 3 must be due to the code in
as_update_iohist.  (akpm: that's not part of this patch.  So this patch is
"Nick").

(akpm: rmk said:

This driver is buggy.  You must not provide your own release function - it
doesn't solve the problem which the warning (which you get when you don't
provide one) is telling you about.

You should convert your device driver over to the replacement dynamic platform
support, once it is merged.  IOW, something like:

	pdev = platform_device_alloc("mydev", id);
	if (pdev) {
		err = platform_device_add_resources(pdev, &resources,
						ARRAY_SIZE(resources));
		if (err == 0)
			err = platform_device_add_data(pdev, &platform_data,
						sizeof(platform_data));
		if (err == 0)
			err = platform_device_add(pdev);
		} else {
			err = -ENOMEM;
		}
		if (err)
			platform_device_put(pdev);

This patch adds a connector that reports fork, exec, id change, and exit
events for all processes to userspace.  It replaces the fork_advisor patch
that ELSA is currently using.  Applications that may find these events
useful include accounting/auditing (e.g.  ELSA), system activity monitoring
(e.g.  top), security, and resource management (e.g.  CKRM).

Peter Oberparleiter 1e0291bade [PATCH] s390: dasd diag with block sizes > 512
Access to FBA disks via DIAG fails for block sizes > 512 byte.  The device
analysis code of the DIAG discipline does not properly initialize the DIAG250
device environment after completion of the analysis.  This results in VM only
serving 512 bytes per block I/O request whereas Linux expects larger block
sizes.  Add proper device environment setup to end of analysis code.

Future versions of gcc may remove initialization code for control blocks used

This may lead to erratic behavior.  Fix the diag250 inline assembly

Paul Mundt 055a251214 [PATCH] superhyway: multiple block support and VCR rework
This extends the API somewhat to allow for platform-specific VCR reading and
writing.  Some platforms (like SH4-202) implement the VCR in a split VCRL and
VCRH, but end up being in reverse order or have other quirks that need to be
dealt with, so we add a set of superhyway_ops per-bus to accomodate this.

We also have to extend the per-device resources somewhat, as some devices now
conveniently split control and data blocks.  So we allow a platform to
register its set of SuperHyway devices via superhyway_add_devices() with the
control block always ordered as the first resource (as this is the one that
userspace cares about).

Add capability for 3c59x driver to use memory-mapped PCI I/O resources.
This may improve performance for those devices so equipped.  This will be
the default behaviour for IS_CYCLONE and IS_TORNADO devices.  Additionally,
it can be enabled/disabled individually for up to MAX_UNITS number of
devices via the use_mmio module option or for all units via the
global_use_mmio option.  The use_mmio option overrides the global_use_mmio
option for those devices specified.
