2007-05-11lib/hexdumpRandy Dunlap1-0/+11
Based on ace_dump_mem() from Grant Likely for the Xilinx SystemACE CompactFlash interface. Add print_hex_dump() & hex_dumper() to lib/hexdump.c and linux/kernel.h. This patch adds the functions print_hex_dump() & hex_dumper(). print_hex_dump() can be used to perform a hex + ASCII dump of data to syslog, in an easily viewable format, thus providing a common text hex dump format. hex_dumper() provides a dump-to-memory function. It converts one "line" of output (16 bytes of input) at a time. Example usages: print_hex_dump(KERN_DEBUG, DUMP_PREFIX_ADDRESS, frame->data, frame->len); hex_dumper(frame->data, frame->len, linebuf, sizeof(linebuf)); Example output using %DUMP_PREFIX_OFFSET: 0009ab42: 40414243 44454647 48494a4b 4c4d4e4f-@ABCDEFG HIJKLMNO Example output using %DUMP_PREFIX_ADDRESS: ffffffff88089af0: 70717273 74757677 78797a7b 7c7d7e7f-pqrstuvw xyz{|}~.

2007-05-11getrusage(): fill ru_inblock and ru_oublock fields if possibleEric Dumazet2-0/+29
If CONFIG_TASK_IO_ACCOUNTING is defined, we update io accounting counters for each task. This patch permits reporting of values using the well known getrusage() syscall, filling ru_inblock and ru_oublock instead of null values. As TASK_IO_ACCOUNTING currently counts bytes counts, we approximate blocks count doing : nr_blocks = nr_bytes / 512 Example of use : ---------------------- After patch is applied, /usr/bin/time command can now give a good approximation of IO that the process had to do. $ /usr/bin/time grep tototo /usr/include/* Command exited with non-zero status 1 0.00user 0.02system 0:02.11elapsed 1%CPU (0avgtext+0avgdata 0maxresident)k 24288inputs+0outputs (0major+259minor)pagefaults 0swaps $ /usr/bin/time dd if=/dev/zero of=/tmp/testfile count=1000 1000+0 enregistrements lus 1000+0 enregistrements écrits 512000 octets (512 kB) copiés, 0,00326601 seconde, 157 MB/s 0.00user 0.00system 0:00.00elapsed 80%CPU (0avgtext+0avgdata 0maxresident)k 0inputs+3000outputs (0major+299minor)pagefaults 0swaps Signed-off-by: Eric Dumazet <dada1@cosmosbay.com> Cc: Oleg Nesterov <oleg@tv-sign.ru> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2007-05-11uml: iRQ stacksJeff Dike1-0/+2
Add a separate IRQ stack. This differs from i386 in having the entire interrupt run on a separate stack rather than starting on the normal kernel stack and switching over once some preparation has been done. The underlying mechanism, is of course, sigaltstack. Another difference is that interrupts that happen in userspace are handled on the normal kernel stack. These cause a wait wakeup instead of a signal delivery so there is no point in trying to switch stacks for these. There's no other stuff on the stack, so there is no extra stack consumption. This quirk makes it possible to have the entire interrupt run on a separate stack - process preemption (and calls to schedule()) happens on a normal kernel stack. If we enable CONFIG_PREEMPT, this will need to be rethought. The IRQ stack for CPU 0 is declared in the same way as the initial kernel stack. IRQ stacks for other CPUs will be allocated dynamically. An extra field was added to the thread_info structure. When the active thread_info is copied to the IRQ stack, the real_thread field points back to the original stack. This makes it easy to tell where to copy the thread_info struct back to when the interrupt is finished. It also serves as a marker of a nested interrupt. It is NULL for the first interrupt on the stack, and non-NULL for any nested interrupts. Care is taken to behave correctly if a second interrupt comes in when the thread_info structure is being set up or taken down. I could just disable interrupts here, but I don't feel like giving up any of the performance gained by not flipping signals on and off. If an interrupt comes in during these critical periods, the handler can't run because it has no idea what shape the stack is in. So, it sets a bit for its signal in a global mask and returns. The outer handler will deal with this signal itself. Atomicity is had with xchg. A nested interrupt that needs to bail out will xchg its signal mask into pending_mask and repeat in case yet another interrupt hit at the same time, until the mask stabilizes. The outermost interrupt will set up the thread_info and xchg a zero into pending_mask when it is done. At this point, nested interrupts will look at ->real_thread and see that no setup needs to be done. They can just continue normally. Similar care needs to be taken when exiting the outer handler. If another interrupt comes in while it is copying the thread_info, it will drop a bit into pending_mask. The outer handler will check this and if it is non-zero, will loop, set up the stack again, and handle the interrupt.

2007-05-11m32r: fix switch_to macro to push/pop frame pointer if neededHirokazu Takata1-0/+11
This patch fixes a rarely-happened but severe scheduling problem of the recent m32r kernel of 2.6.17-rc3 or later. In the following previous m32r patch, the switch_to macro was modified not to do unnecessary push/pop operations for tuning. > [PATCH] m32r: update switch_to macro for tuning > 4127272c38619c56f0c1aa01d01c7bd757db70a1 In this modification, only 'lr' and 'sp' registers are push/pop'ed, assuming that the m32r kernel is always compiled with -fomit-frame-pointer option. However, in 2.6 kernel, kernel/sched.c is irregularly compiled with -fno-omit-frame-pointer if CONFIG_SCHED_NO_NO_OMIT_FRAME_POINTER is not defined. -- kernel/Makefile -- : ifneq ($(CONFIG_SCHED_NO_NO_OMIT_FRAME_POINTER),y) # According to Alan Modra <alan@linuxcare.com.au>, the -fno-omit-frame-pointer is # needed for x86 only. Why this used to be enabled for all architectures is beyond # me. I suspect most platforms don't need this, but until we know that for sure # I turn this off for IA-64 only. Andreas Schwab says it's also needed on m68k # to get a correct value for the wait-channel (WCHAN in ps). --davidm CFLAGS_sched.o := $(PROFILING) -fno-omit-frame-pointer endif : --- Therefore, for the recent m32r kernel, we have to push/pop 'fp' (frame pointer) if CONFIG_FRAME_POINTER is defined or CONFIG_SCHED_NO_NO_OMIT_FRAME_POINTER is not defined.

2007-05-10Revert "[PATCH] paravirt: Add startup infrastructure for paravirtualization"Eric W. Biederman1-5/+0
This reverts commit c9ccf30d77f04064fe5436027ab9d2230c7cdd94. Entering the kernel at startup_32 without passing our real mode data in %esi, and without guaranteeing that physical and virtual addresses are identity mapped makes head.S impossible to maintain. The only user of this infrastructure is lguest which is not merged so nothing we currently support will break by removing this over designed nightmare, and only the pending lguest patches will be affected. The pending Xen patches have a different entry point that they use. We are currently discussing what Xen and lguest need to do to boot the kernel in a more normal fashion so using startup_32 in this weird manner is clearly not their long term direction. So let's remove this code in head.S before it causes brain damage to people trying to maintain head.S Cc: Chris Wright <chrisw@sous-sol.org> Cc: Andi Kleen <ak@suse.de> Cc: Jeremy Fitzhardinge <jeremy@goop.org> Cc: Zachary Amsden <zach@vmware.com> CC: H.

2007-05-10slub: support concurrent local and remote frees and allocs on a slabChristoph Lameter1-2/+5
Avoid atomic overhead in slab_alloc and slab_free SLUB needs to use the slab_lock for the per cpu slabs to synchronize with potential kfree operations. This patch avoids that need by moving all free objects onto a lockless_freelist. The regular freelist continues to exist and will be used to free objects. So while we consume the lockless_freelist the regular freelist may build up objects. If we are out of objects on the lockless_freelist then we may check the regular freelist. If it has objects then we move those over to the lockless_freelist and do this again. There is a significant savings in terms of atomic operations that have to be performed. We can even free directly to the lockless_freelist if we know that we are running on the same processor. So this speeds up short lived objects. They may be allocated and freed without taking the slab_lock. This is particular good for netperf. In order to maximize the effect of the new faster hotpath we extract the hottest performance pieces into inlined functions. These are then inlined into kmem_cache_alloc and kmem_cache_free. So hotpath allocation and freeing no longer requires a subroutine call within SLUB. [I am not sure that it is worth doing this because it changes the easy to read structure of slub just to reduce atomic ops. However, there is someone out there with a benchmark on 4 way and 8 way processor systems that seems to show a 5% regression vs. Slab. Seems that the regression is due to increased atomic operations use vs. SLAB in SLUB). I wonder if this is applicable or discernable at all in a real workload?] Signed-off-by: Christoph Lameter <clameter@sgi.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2007-05-10acpi,msi-laptop: Fall back to EC polling mode for MSI laptop specific EC ↵Lennart Poettering1-1/+2
commands The ACPI EC that is used in MSI laptops knows some non-standard commands for changing the screen brighntess and a few other things, which are used by the msi-laptop.c driver. Unfortunately for these commands no GPE events for IBF and OBF are triggered. Since nowadays the EC code uses the ec_intr=1 mode by default, this causes these operations to timeout, although they don't fail. In result, all operations that you can do with the msi-laptop.c driver take more or less 1s to complete, which is awfully slow. In one of the more recent kernels (2.6.20?) the EC subsystem has been revamped. With that change the EC timeout has been increased. before that increase the MSI EC accesses were slow -- but not *that* slow, hence I took notice of this limitation of the MSI EC hardware only very recently. The standard EC operations on the MSI EC as defined in the ACPI spec support GPE events properly. The following patch adds a new argument "force_poll" to the ec_transaction() function (and friends). If set to 1, the function will poll for IBF/OBF even if ec_intr=1 is enabled. If set to 0 the current behaviour is used. The msi-laptop driver is modified to make use of this new flag, so that OBF/IBF is polled for the special MSI EC transactions -- but only for them.

2007-05-09[POWERPC] User rheap from arch/powerpc/libKumar Gala1-0/+0
Removed rheap in arch/ppc/lib and changed build system to use the one in arch/powerpc/lib. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2007-05-09[POWERPC] Change rheap functions to use ulongs instead of pointersTimur Tabi4-37/+22
The rheap allocation functions return a pointer, but the actual value is based on how the heap was initialized, and so it can be anything, e.g. an offset into a buffer. A ulong is a better representation of the value returned by the allocation functions. This patch changes all of the relevant rheap functions to use a unsigned long integers instead of a pointer. In case of an error, the value returned is a negative error code that has been cast to an unsigned long. The caller can use the IS_ERR_VALUE() macro to check for this. All code which calls the rheap functions is updated accordingly. Macros IS_MURAM_ERR() and IS_DPERR(), have been deleted in favor of IS_ERR_VALUE(). Also added error checking to rh_attach_region().

2007-05-09Revert "ACPICA: fix AML mutex re-entrancy"Len Brown2-3/+2
This reverts commit c0d127b56937c3e72c2b1819161d2f6718eee877. These changes to AML locking were made to allow Notify handlers to be called on the stack and not deadlock. However, that scheme turns out to be flawed and was reverted by the previous commit, so this commit restores the locking to it previous design. Signed-off-by: Len Brown <len.brown@intel.com>
2007-05-09Revert "ACPICA: revert "acpi_serialize" changes"Len Brown1-1/+5
This reverts commit a8f4af6dc6600980885c594f52eecd60edd62013. Thus restoring ACPICA's new acpi_serialize code. This commit by itself may cause a regression, but it is reverted in this order so that subsequent reverts reverts under this one can be made without conflict.

2007-05-09Revert "md: improve partition detection in md array"Linus Torvalds1-0/+1
This reverts commit 5b479c91da90eef605f851508744bfe8269591a0. Quoth Neil Brown: "It causes an oops when auto-detecting raid arrays, and it doesn't seem easy to fix. The array may not be 'open' when do_md_run is called, so bdev->bd_disk might be NULL, so bd_set_size can oops. This whole approach of opening an md device before it has been assembled just seems to get more and more painful. I think I'm going to have to come up with something clever to provide both backward comparability with usage expectation, and sane integration into the rest of the kernel."

2007-05-10ide: legacy PCI bus order probing fixesBartlomiej Zolnierkiewicz1-0/+5
IDE PCI host drivers should register themselves with IDE core only when IDE driver is built-in, otherwise (IDE driver is modular and thus IDE PCI host drivers are also modular) the code has no effect and just complicates the probing. Fix it by adding new config option CONFIG_IDEPCI_PCIBUS (defined only when needed and invisible to the user) and covering by #ifdef/#endif the code in question. It turned out that "ide=reverse" was silently accepted but did nothing in case when IDE driver was modular, this is fixed now. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2007-05-10ide: add ide_proc_register_port()Bartlomiej Zolnierkiewicz1-6/+4
* create_proc_ide_interfaces() tries to add /proc entries for every probed and initialized IDE port, replace it by ide_proc_register_port() which does it only for the given port (also rename destroy_proc_ide_interface() to ide_proc_unregister_port() for consistency) * convert {create,destroy}_proc_ide_interface[s]() users to use new functions * pmac driver depended on proc_ide_create() to add /proc port entries, fix it * au1xxx-ide, swarm and cs5520 drivers depended indirectly on ide-generic driver (CONFIG_IDE_GENERIC=y) to add port /proc entries, fix them * there is now no need to add /proc entries for IDE ports in proc_ide_create() so don't do it * proc_ide_create() needs now to be called before drivers are probed - fix it, while at it make proc_ide_create() create /proc "ide" directory Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

Tejun's recent eighty_ninty_three() fix has inspired me to do more thorough review of the cable detection code... * print user-friendly warning about limiting the maximum transfer speed to UDMA33 (and the reason behind it) when 80-wire cable is not detected, also while at it cleanup eighty_ninty_three() a bit * use eighty_ninty_three() in ide_ata66_check(), this actually fixes 3 bugs: - bit 14 (word 93 validity check) == 1 && bit 13 (80-wire cable test) == 1 were used as 80-wire cable present test for CONFIG_IDEDMA_IVB=n case (please see FIXME comment in eighty_ninty_three() for more details) - CONFIG_IDEDMA_IVB=y/n cases were interchanged - check for SATA devices was missing * remove private cable warnings from pdc_202xx{old,new} drivers now that core code provides this functionality (plus, in pdc202xx_new case the test could give false warnings for ATAPI devices because pdc202xx_new driver doesn't even support ATAPI DMA) Cc: Tejun Heo <htejun@gmail.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
