* [PATCH] kmemdup: introduceAlexey Dobriyan2006-10-011-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | One of idiomatic ways to duplicate a region of memory is dst = kmalloc(len, GFP_KERNEL); if (!dst) return -ENOMEM; memcpy(dst, src, len); which is neat code except a programmer needs to write size twice. Which sometimes leads to mistakes. If len passed to kmalloc is smaller that len passed to memcpy, it's straight overwrite-beyond-end. If len passed to memcpy is smaller than len passed to kmalloc, it's either a) legit behaviour ;-), or b) cloned buffer will contain garbage in second half. Slight trolling of commit lists shows several duplications bugs done exactly because of diverged lenghts: Linux: [CRYPTO]: Fix memcpy/memset args. [PATCH] memcpy/memset fixes OpenBSD: kerberosV/src/lib/asn1: der_copy.c:1.4 If programmer is given only one place to play with lengths, I believe, such mistakes could be avoided. With kmemdup, the snippet above will be rewritten as: dst = kmemdup(src, len, GFP_KERNEL); if (!dst) return -ENOMEM; This also leads to smaller code (kzalloc effect). Quick grep shows 200+ places where kmemdup() can be used.

* [PATCH] maximum latency tracking: ALSA supportTakashi Iwai2006-10-011-0/+1
| | | | | | | | | | | | | | | | | | | | | | Add maximum latency tracking to the ALSA subsystem for PCM playback. In ALSA, the playback application controls the buffer size and thus indirectly the period of latency that it can deal with. This patch uses 75% of the total available latency as threshold to announce to the latency subsystem; While 75% is a crude heuristic it's a quite reasonable one; the remaining 25% can be used for all driver processing for the next samples which is also proportional to the size of the buffer. With ogg123 a latency setting of about 4msec was seen (at 44Khz), while with the "play" command a much longer maximum tolerable latency was seen. Other, more multimedia oriented players as well as games, will have a lot smaller buffers to allow better synchronization and those will actually get into the latency domains where there is impact on the power management rules.

* [PATCH] maximum latency tracking infrastructureArjan van de Ven2006-10-011-0/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add infrastructure to track "maximum allowable latency" for power saving policies. The reason for adding this infrastructure is that power management in the idle loop needs to make a tradeoff between latency and power savings (deeper power save modes have a longer latency to running code again). The code that today makes this tradeoff just does a rather simple algorithm; however this is not good enough: There are devices and use cases where a lower latency is required than that the higher power saving states provide. An example would be audio playback, but another example is the ipw2100 wireless driver that right now has a very direct and ugly acpi hook to disable some higher power states randomly when it gets certain types of error. The proposed solution is to have an interface where drivers can * announce the maximum latency (in microseconds) that they can deal with * modify this latency * give up their constraint and a function where the code that decides on power saving strategy can query the current global desired maximum. This patch has a user of each side: on the consumer side, ACPI is patched to use this, on the producer side the ipw2100 driver is patched. A generic maximum latency is also registered of 2 timer ticks (more and you lose accurate time tracking after all). While the existing users of the patch are x86 specific, the infrastructure is not. I'd like to ask the arch maintainers of other architectures if the infrastructure is generic enough for their use (assuming the architecture has such a tradeoff as concept at all), and the sound/multimedia driver owners to look at the driver facing API to see if this is something they can use.

* [PATCH] PCI quirks updateAlan Cox2006-10-011-2/+3
| | | | | | | | | | | | | | | | | | | | | | | This fixes two things Firstly someone mistakenly used "errata" for the singular. This causes Dave Woodhouse to emit diagnostics whenever the string is read, and so should be fixed. Secondly the AMD AGP tunnel has an erratum which causes hangs if you try and do direct PCI to AGP transfers in some cases. We have a flag for PCI/PCI failures but we need a different flag for this really as in this case we don't want to stop PCI/PCI transfers using things like IOAT and the new RAID offload work. I'll post some updates to make proper use of the PCIAGP flag in the media/video drivers to Mauro.

* [PATCH] BLOCK: Make it possible to disable the block layer [try #6]David Howells2006-09-3010-18/+94
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make it possible to disable the block layer. Not all embedded devices require it, some can make do with just JFFS2, NFS, ramfs, etc - none of which require the block layer to be present. This patch does the following: (*) Introduces CONFIG_BLOCK to disable the block layer, buffering and blockdev support. (*) Adds dependencies on CONFIG_BLOCK to any configuration item that controls an item that uses the block layer. This includes: (*) Block I/O tracing. (*) Disk partition code. (*) All filesystems that are block based, eg: Ext3, ReiserFS, ISOFS. (*) The SCSI layer. As far as I can tell, even SCSI chardevs use the block layer to do scheduling. Some drivers that use SCSI facilities - such as USB storage - end up disabled indirectly from this. (*) Various block-based device drivers, such as IDE and the old CDROM drivers. (*) MTD blockdev handling and FTL. (*) JFFS - which uses set_bdev_super(), something it could avoid doing by taking a leaf out of JFFS2's book. (*) Makes most of the contents of linux/blkdev.h, linux/buffer_head.h and linux/elevator.h contingent on CONFIG_BLOCK being set. sector_div() is, however, still used in places, and so is still available. (*) Also made contingent are the contents of linux/mpage.h, linux/genhd.h and parts of linux/fs.h. (*) Makes a number of files in fs/ contingent on CONFIG_BLOCK. (*) Makes mm/bounce.c (bounce buffering) contingent on CONFIG_BLOCK. (*) set_page_dirty() doesn't call __set_page_dirty_buffers() if CONFIG_BLOCK is not enabled. (*) fs/no-block.c is created to hold out-of-line stubs and things that are required when CONFIG_BLOCK is not set: (*) Default blockdev file operations (to give error ENODEV on opening). (*) Makes some /proc changes: (*) /proc/devices does not list any blockdevs. (*) /proc/diskstats and /proc/partitions are contingent on CONFIG_BLOCK. (*) Makes some compat ioctl handling contingent on CONFIG_BLOCK. (*) If CONFIG_BLOCK is not defined, makes sys_quotactl() return -ENODEV if given command other than Q_SYNC or if a special device is specified. (*) In init/do_mounts.c, no reference is made to the blockdev routines if CONFIG_BLOCK is not defined. This does not prohibit NFS roots or JFFS2. (*) The bdflush, ioprio_set and ioprio_get syscalls can now be absent (return error ENOSYS by way of cond_syscall if so). (*) The seclvl_bd_claim() and seclvl_bd_release() security calls do nothing if CONFIG_BLOCK is not set, since they can't then happen.

| | | | | | | | | | | | | None of the in-kernel primitives for handling "atomic" counting seem to be a good fit.

* [PATCH] cfq-iosched: kill cfq_exit_lockJens Axboe2006-09-301-1/+1
| | | | | | | | | | | | | | | | | | | | | cfq_exit_lock is protecting two things now: - The per-ioc rbtree of cfq_io_contexts - The per-cfqd linked list of cfq_io_contexts The per-cfqd linked list can be protected by the queue lock, as it is (by definition) per cfqd as the queue lock is. The per-ioc rbtree is mainly used and updated by the process itself only. The only outside use is the io priority changing. If we move the priority changing to not browsing the rbtree, we can remove any locking from the rbtree updates and lookup completely. Let the sys_ioprio syscall just mark processes as having the iopriority changed and lazily update the private cfq io contexts the next time io is queued, and we can remove this locking as well.

| | | | | | | | | | | After Christophs SCSI change, the only usage left is RQ_ACTIVE and RQ_INACTIVE.

| * V4L/DVB (4348): Fix: compile for radio aimslab and aztech with V4L2 onlyMauro Carvalho Chehab2006-09-261-3/+7
| | | | | | | | | | | | | | | | | | | | All radio devices use an obsolete mode of opening/release driver. Since this is not V4L1 core, better to keep the method available for more time than to rewrite open/release without a radio device to test, since the newer method is much more complex than the previous one (although providing support for multiple opens and multiple devices).
