| * [CPUFREQ] state info wrong after resumeShaohua Li2008-04-281-1/+1
| | | | | | | | | | | | | | | | | | | | | | Sometimes old_index != stat->last_index, see cpufreq_update_policy, bios can change cpu setting in resume. In my test, after resume cpu is in lowest speed, but the stat info shows cpu is in full speed. This patch makes the stat info correct after a resume.

| * [CPUFREQ] expose cpufreq coordination requirements regardless of ↵Darrick J. Wong2008-04-283-6/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | coordination mechanism Currently, affected_cpus shows which CPUs need to have their frequency coordinated in software. When hardware coordination is in use, the contents of this file appear the same as when no coordination is required. This can lead to some confusion among user-space programs, for example, that do not know that extra coordination is required to force a CPU core to a particular speed to control power consumption. To fix this, create a "related_cpus" attribute that always displays the coordination map regardless of whatever coordination strategy the cpufreq driver uses (sw or hw). If the cpufreq driver does not provide a value, fall back to policy->cpus. Signed-off-by: Darrick J.

| * | block: Skip I/O merges when disabledAlan D. Brunelle2008-04-293-0/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The block I/O + elevator + I/O scheduler code spend a lot of time trying to merge I/Os -- rightfully so under "normal" circumstances. However, if one were to know that the incoming I/O stream was /very/ random in nature, the cycles are wasted. This patch adds a per-request_queue tunable that (when set) disables merge attempts (beyond the simple one-hit cache check), thus freeing up a non-trivial amount of CPU cycles. Signed-off-by: Alan D.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch changes rq->cmd from the static array to a pointer to support large commands. We rarely handle large commands. So for optimization, a struct request still has a static array for a command. rq_init sets rq->cmd pointer to the static array.

Reuse in another (possibly 32-bit) driver is protected by the safety net called `compiler warning' (with the cast, it may silently truncate to 32-bit). If sector_t ever changes, we will get a compiler warning as well (with the cast, we won't).

The upside is that we can now require an rq_init() from any path that wishes to hand the request to the block layer. rq_init() will be exported for the code that uses struct request without blk_get_request. This is a preparation for large command support, which needs to initialize struct request in a proper way (that is, just doing a memset() will not work).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The mapsize optimizations which were moved from x86 to the generic code in commit 64970b68d2b3ed32b964b0b30b1b98518fde388e increased the binary size on non x86 architectures. Looking into the real effects of the "optimizations" it turned out that they are not used in find_next_bit() and find_next_zero_bit(). The ones in find_first_bit() and find_first_zero_bit() are used in a couple of places but none of them is a real hot path. Remove the "optimizations" all together and call the library functions unconditionally. Boot-tested on x86 and compile tested on every cross compiler I have.

Put them into include/linux/kbuild.h file. Also add a new feature COMMENT("text") which can be used to insert lines of ocmments into asm-offsets.h and bounds.h.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use vmalloc() and memset() instead of kcalloc() to allocate a page* array when the array size is bigger than one page. This enables relayfs to support bigger relay buffers than 64MB on 4k-page system, 512MB on 16k-page system.
