Raw Normal View History

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

Introduce HAVE_AOUT symbol to remove hard-coded arch list for BINFMT_AOUT HAVE_AOUT doesn't quite do the same thing as the recently removed ARCH_SUPPORTS_AOUT config option. That was set even on platforms where binfmt_aout isn't supported, although it's not entirely clear why. So it's best just to introduce a new symbol, handled consistently with other similar HAVE_xxx symbols; with a simple 'select' in the arch Kconfig.

Add HAVE_OPROFILE Linus: On the per-architecture side, I do think it would be better to *not* have internal architecture knowledge in a generic file, and as such a line like depends on X86_32 || IA64 || PPC || S390 || SPARC64 || X86_64 || AVR32 really shouldn't exist in a file like kernel/Kconfig.instrumentation. It would be much better to do depends on ARCH_SUPPORTS_KPROBES in that generic file, and then architectures that do support it would just have a bool ARCH_SUPPORTS_KPROBES default y in *their* architecture files. That would seem to be much more logical, and is readable both for arch maintainers *and* for people who have no clue - and don't care - about which architecture is supposed to support which interface... Changelog: Actually, I know I gave this as the magic incantation, but now that I see it, I realize that I should have told you to just use config ARCH_SUPPORTS_KPROBES def_bool y instead, which is a bit denser. We seem to use both kinds of syntax for these things, but this is really what "def_bool" is there for... Changelog : - Moving to HAVE_*. - Add AVR32 oprofile.

Add Kconfig option ARCH_HAVE_NMI_SAFE_CMPXCHG cmpxchg() is widely used by lockless code, including NMI-safe lockless code. But on some architectures, the cmpxchg() implementation is not NMI-safe, on these architectures the lockless code may need a spin_trylock_irqsave() based implementation. This patch adds a Kconfig option: ARCH_HAVE_NMI_SAFE_CMPXCHG, so that NMI-safe lockless code can depend on it or provide different implementation according to it. On many architectures, cmpxchg is only NMI-safe for several specific operand sizes. So, ARCH_HAVE_NMI_SAFE_CMPXCHG define in this patch only guarantees cmpxchg is NMI-safe for sizeof(unsigned long).

alpha: Use new generic strncpy_from_user() and strnlen_user() Similar to x86/sparc/powerpc implementations except: 1) we implement an extremely efficient has_zero()/find_zero() sequence with both prep_zero_mask() and create_zero_mask() no-operations. 2) Our output from prep_zero_mask() differs in that only the lowest eight bits are used to represent the zero bytes nevertheless it can be safely ORed with other similar masks from prep_zero_mask() and forms input to create_zero_mask(), the two fundamental properties prep_zero_mask() must satisfy. Tests on EV67 and EV68 CPUs revealed that the generic code is essentially as fast (to within 0.5% of CPU cycles) of the old Alpha specific code for large quadword-aligned strings, despite the 30% extra CPU instructions executed. In contrast, the generic code for unaligned strings is substantially slower (by more than a factor of 3) than the old Alpha specific code.

Make most arch asm/module.h files use asm-generic/module.h Use the mapping of Elf_[SPE]hdr, Elf_Addr, Elf_Sym, Elf_Dyn, Elf_Rel/Rela, ELF_R_TYPE() and ELF_R_SYM() to either the 32-bit version or the 64-bit version into asm-generic/module.h for all arches bar MIPS. Also, use the generic definition mod_arch_specific where possible. To this end, I've defined three new config bools: (*) HAVE_MOD_ARCH_SPECIFIC Arches define this if they don't want to use the empty generic mod_arch_specific struct. (*) MODULES_USE_ELF_RELA Arches define this if their modules can contain RELA records. This causes the Elf_Rela mapping to be emitted and allows apply_relocate_add() to be defined by the arch rather than have the core emit an error message. (*) MODULES_USE_ELF_REL Arches define this if their modules can contain REL records. This causes the Elf_Rel mapping to be emitted and allows apply_relocate() to be defined by the arch rather than have the core emit an error message. Note that it is possible to allow both REL and RELA records: m68k and mips are two arches that do this. With this, some arch asm/module.h files can be deleted entirely and replaced with a generic-y marker in the arch Kbuild file. Additionally, I have removed the bits from m32r and score that handle the unsupported type of relocation record as that's now handled centrally.

[PATCH] LOG2: Implement a general integer log2 facility in the kernel This facility provides three entry points: ilog2() Log base 2 of unsigned long ilog2_u32() Log base 2 of u32 ilog2_u64() Log base 2 of u64 These facilities can either be used inside functions on dynamic data: int do_something(long q) { ...; y = ilog2(x) ...; } Or can be used to statically initialise global variables with constant values: unsigned n = ilog2(27); When performing static initialisation, the compiler will report "error: initializer element is not constant" if asked to take a log of zero or of something not reducible to a constant. They treat negative numbers as unsigned. When not dealing with a constant, they fall back to using fls() which permits them to use arch-specific log calculation instructions - such as BSR on x86/x86_64 or SCAN on FRV - if available.

[PATCH] Set CONFIG_ZONE_DMA for arches with GENERIC_ISA_DMA As Andi pointed out: CONFIG_GENERIC_ISA_DMA only disables the ISA DMA channel management. Other functionality may still expect GFP_DMA to provide memory below 16M. So we need to make sure that CONFIG_ZONE_DMA is set independent of CONFIG_GENERIC_ISA_DMA. Undo the modifications to mm/Kconfig where we made ZONE_DMA dependent on GENERIC_ISA_DMA and set theses explicitly in each arches Kconfig. Reviews must occur for each arch in order to determine if ZONE_DMA can be switched off. It can only be switched off if we know that all devices supported by a platform are capable of performing DMA transfers to all of memory (Some arches already support this: uml, avr32, sh sh64, parisc and IA64/Altix). In order to switch ZONE_DMA off conditionally, one would have to establish a scheme by which one can assure that no drivers are enabled that are only capable of doing I/O to a part of memory, or one needs to provide an alternate means of performing an allocation from a specific range of memory (like provided by alloc_pages_range()) and insure that all drivers use that call. In that case the arches alloc_dma_coherent() may need to be modified to call alloc_pages_range() instead of relying on GFP_DMA.

container freezer: implement freezer cgroup subsystem This patch implements a new freezer subsystem in the control groups framework. It provides a way to stop and resume execution of all tasks in a cgroup by writing in the cgroup filesystem. The freezer subsystem in the container filesystem defines a file named freezer.state. Writing "FROZEN" to the state file will freeze all tasks in the cgroup. Subsequently writing "RUNNING" will unfreeze the tasks in the cgroup. Reading will return the current state. * Examples of usage : # mkdir /containers/freezer # mount -t cgroup -ofreezer freezer /containers # mkdir /containers/0 # echo $some_pid > /containers/0/tasks to get status of the freezer subsystem : # cat /containers/0/freezer.state RUNNING to freeze all tasks in the container : # echo FROZEN > /containers/0/freezer.state # cat /containers/0/freezer.state FREEZING # cat /containers/0/freezer.state FROZEN to unfreeze all tasks in the container : # echo RUNNING > /containers/0/freezer.state # cat /containers/0/freezer.state RUNNING This is the basic mechanism which should do the right thing for user space task in a simple scenario. It's important to note that freezing can be incomplete. In that case we return EBUSY. This means that some tasks in the cgroup are busy doing something that prevents us from completely freezing the cgroup at this time. After EBUSY, the cgroup will remain partially frozen -- reflected by freezer.state reporting "FREEZING" when read.

Find out whether you have ISA slots on your motherboard. ISA is the
name of a bus system, i.e. the way the CPU talks to the other stuff
inside your box. Other bus systems are PCI, EISA, MicroChannel
(MCA) or VESA. ISA is an older system, now being displaced by PCI;
newer boards don't support it. If you have ISA, say Y, otherwise N.
[PATCH] ISA DMA Kconfig fixes - part 1 A bunch of drivers use ISA DMA helpers or their equivalents for platforms that have ISA with different DMA controller (a lot of ARM boxen). Currently there is no way to put such dependency in Kconfig - CONFIG_ISA is not it (e.g. it is not set on platforms that have no ISA slots, but have on-board devices that pretend to be ISA ones). New symbol added - ISA_DMA_API. Set when we have functional enable_dma()/set_dma_mode()/etc. set of helpers. Next patches in the series will add missing dependencies for drivers that need them. I'm very carefully staying the hell out of the recurring flamefest on what exactly CONFIG_ISA would mean in ideal world - added symbol has a well-defined meaning and for now I really want to treat it as completely independent from the mess around CONFIG_ISA.

ALPHA: support graphics on non-zero PCI domains This code replaces earlier and incomplete handling of graphics on non-zero PCI domains (aka hoses or peer PCI buses). An option (CONFIG_VGA_HOSE) is set TRUE if configuring a GENERIC kernel, or a kernel for MARVEL, TITAN, or TSUNAMI machines, as these are the machines whose SRM consoles are capable of configuring and handling graphics options on non-zero hoses. All other machines have the option set FALSE. A routine, "find_console_vga_hose()", is used to find the graphics device which the machine's firmware believes is the console device, and it sets a global (pci_vga_hose) for later use in managing access to the device. This is called in "init_arch" on TITAN and TSUNAMI machines; MARVEL machines use a custom version of this routine because of extra complexity. A routine, "locate_and_init_vga()", is used to find the graphics device and set a global (pci_vga_hose) for later use in managing access to the device, in the case where "find_console_vga_hose" has failed. Various adjustments are made to the ioremap and ioportmap routines for detecting and translating "legacy" VGA register and memory references to the real PCI domain.

There are two different types of booting firmware on Alphas: SRM,
which is command line driven, and ARC, which uses menus and arrow
keys. Details about the Linux/Alpha booting process are contained in
the Linux/Alpha FAQ, accessible on the WWW from
<http://www.alphalinux.org/>.
The usual way to load Linux on an Alpha machine is to use MILO
(a bootloader that lets you pass command line parameters to the
kernel just like lilo does for the x86 architecture) which can be
loaded either from ARC or can be installed directly as a permanent
firmware replacement from floppy (which requires changing a certain
jumper on the motherboard). If you want to do either of these, say N
here. If MILO doesn't work on your system (true for Jensen
motherboards), you can bypass it altogether and boot Linux directly
from an SRM console; say Y here in order to do that. Note that you
won't be able to boot from an IDE disk using SRM.
If unsure, say N.

[PATCH] Kconfig fix (BLK_DEV_FD dependencies) Sanitized and fixed floppy dependencies: split the messy dependencies for BLK_DEV_FD by introducing a new symbol (ARCH_MAY_HAVE_PC_FDC), making BLK_DEV_FD depend on that one and taking declarations of ARCH_MAY_HAVE_PC_FDC to arch/*/Kconfig. While we are at it, fixed several obvious cases when BLK_DEV_FD should have been excluded (architectures lacking asm/floppy.h are *not* going to have floppy.c compile, let alone work). If you can come up with better name for that ("this architecture might have working PC-compatible floppy disk controller"), you are more than welcome - just s/ARCH_MAY_HAVE_PC_FDC/your_prefered_name/g in the patch below...

If you say N here, the kernel will run on single and multiprocessor

you say Y here, the kernel will run on many, but not all,
singleprocessor machines. On a singleprocessor machine, the kernel
will run faster if you say N here.

[PATCH] Configurable NODES_SHIFT Current implementations define NODES_SHIFT in include/asm-xxx/numnodes.h for each arch. Its definition is sometimes configurable. Indeed, ia64 defines 5 NODES_SHIFT values in the current git tree. But it looks a bit messy. SGI-SN2(ia64) system requires 1024 nodes, and the number of nodes already has been changeable by config. Suitable node's number may be changed in the future even if it is other architecture. So, I wrote configurable node's number. This patch set defines just default value for each arch which needs multi nodes except ia64. But, it is easy to change to configurable if necessary. On ia64 the number of nodes can be already configured in generic ia64 and SN2 config. But, NODES_SHIFT is defined for DIG64 and HP'S machine too. So, I changed it so that all platforms can be configured via CONFIG_NODES_SHIFT. It would be simpler.

be streamlined if we restrict the kernel to one PGD for all vmalloc
allocations. This equates to about 8GB.
Under normal circumstances, this is so far and above what is needed
as to be laughable. However, there are certain applications (such
as benchmark-grade in-kernel web serving) that can make use of as
much vmalloc space as is available.
Say N unless you know you need gobs and gobs of vmalloc space.
config VERBOSE_MCHECK
bool "Verbose Machine Checks"
config VERBOSE_MCHECK_ON
int "Verbose Printing Mode (0=off, 1=on, 2=all)"
depends on VERBOSE_MCHECK
default 1
---help---
This option allows the default printing mode to be set, and then
possibly overridden by a boot command argument.
For example, if one wanted the option of printing verbose
machine checks, but wanted the default to be as if verbose
machine check printing was turned off, then one would choose
the printing mode to be 0. Then, upon reboot, one could add
the boot command line "verbose_mcheck=1" to get the normal
verbose machine check printing, or "verbose_mcheck=2" to get
the maximum information available.
Take the default (1) unless you want more control or more info.
avoid overflows in kernel/time.c When the conversion factor between jiffies and milli- or microseconds is not a single multiply or divide, as for the case of HZ == 300, we currently do a multiply followed by a divide. The intervening result, however, is subject to overflows, especially since the fraction is not simplified (for HZ == 300, we multiply by 300 and divide by 1000). This is exposed to the user when passing a large timeout to poll(), for example. This patch replaces the multiply-divide with a reciprocal multiplication on 32-bit platforms. When the input is an unsigned long, there is no portable way to do this on 64-bit platforms there is no portable way to do this since it requires a 128-bit intermediate result (which gcc does support on 64-bit platforms but may generate libgcc calls, e.g. on 64-bit s390), but since the output is a 32-bit integer in the cases affected, just simplify the multiply-divide (*3/10 instead of *300/1000). The reciprocal multiply used can have off-by-one errors in the upper half of the valid output range. This could be avoided at the expense of having to deal with a potential 65-bit intermediate result. Since the intent is to avoid overflow problems and most of the other time conversions are only semiexact, the off-by-one errors were considered an acceptable tradeoff. At Ralf Baechle's suggestion, this version uses a Perl script to compute the necessary constants. We already have dependencies on Perl for kernel compiles. This does, however, require the Perl module Math::BigInt, which is included in the standard Perl distribution starting with version 5.8.0. In order to support older versions of Perl, include a table of canned constants in the script itself, and structure the script so that Math::BigInt isn't required if pulling values from said table. Running the script requires that the HZ value is available from the Makefile. Thus, this patch also adds the Kconfig variable CONFIG_HZ to the architectures which didn't already have it (alpha, cris, frv, h8300, m32r, m68k, m68knommu, sparc, v850, and xtensa.) It does *not* touch the sh or sh64 architectures, since Paul Mundt has dealt with those separately in the sh tree. Signed-off-by: H.

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it.

config SRM_ENV
tristate "SRM environment through procfs"
depends on PROC_FS
---help---
If you enable this option, a subdirectory inside /proc called
/proc/srm_environment will give you access to the all important
SRM environment variables (those which have a name) and also
to all others (by their internal number).
SRM is something like a BIOS for Alpha machines. There are some
other such BIOSes, like AlphaBIOS, which this driver cannot
support (hey, that's not SRM!).
Despite the fact that this driver doesn't work on all Alphas (but
only on those which have SRM as their firmware), it's save to
build it even if your particular machine doesn't know about SRM
(or if you intend to compile a generic kernel). It will simply
not create those subdirectory in /proc (and give you some warning,
of course).
This driver is also available as a module and will be called
srm_env then.

[NET]: add a top-level Networking menu to *config Create a new top-level menu named "Networking" thus moving net related options and protocol selection way from the drivers menu and up on the top-level where they belong. To implement this all architectures has to source "net/Kconfig" before drivers/*/Kconfig in their Kconfig file. This change has been implemented for all architectures. Device drivers for ordinary NIC's are still to be found in the Device Drivers section, but Bluetooth, IrDA and ax25 are located with their corresponding menu entries under the new networking menu item.

ALPHA: support graphics on non-zero PCI domains This code replaces earlier and incomplete handling of graphics on non-zero PCI domains (aka hoses or peer PCI buses). An option (CONFIG_VGA_HOSE) is set TRUE if configuring a GENERIC kernel, or a kernel for MARVEL, TITAN, or TSUNAMI machines, as these are the machines whose SRM consoles are capable of configuring and handling graphics options on non-zero hoses. All other machines have the option set FALSE. A routine, "find_console_vga_hose()", is used to find the graphics device which the machine's firmware believes is the console device, and it sets a global (pci_vga_hose) for later use in managing access to the device. This is called in "init_arch" on TITAN and TSUNAMI machines; MARVEL machines use a custom version of this routine because of extra complexity. A routine, "locate_and_init_vga()", is used to find the graphics device and set a global (pci_vga_hose) for later use in managing access to the device, in the case where "find_console_vga_hose" has failed. Various adjustments are made to the ioremap and ioportmap routines for detecting and translating "legacy" VGA register and memory references to the real PCI domain.
