| * cfq-iosched: Fix the incorrect timeslice accounting with forced_dispatchDivyesh Shah2010-04-091-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When CFQ dispatches requests forcefully due to a barrier or changing iosched, it runs through all cfqq's dispatching requests and then expires each queue. However, it does not activate a cfqq before flushing its IOs resulting in using stale values for computing slice_used. This patch fixes it by calling activate queue before flushing reuqests from each queue. This is useful mostly for barrier requests because when the iosched is changing it really doesnt matter if we have incorrect accounting since we're going to break down all structures anyway. We also now expire the current timeslice before moving on with the dispatch to accurately account slice used for that cfqq.

| | | | | | | | | | | | | | | | | | | | | | | | Currently, the io statistics for the root cgroup are maintained, but they are not shown because the device information is not available at the point that the root blkio cgroup is created. This patch updates the device information when the statistics are updated so that the statistics become visible.

| * backing-dev: Handle class_create() failureAnton Blanchard2010-04-021-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | I hit this when we had a bug in IDR for a few days. Basically sysfs would fail to create new inodes since it uses an IDR and therefore class_create would fail. While we are unlikely to see this fail we may as well handle it instead of oopsing.

| * cfq-iosched: Do not merge queues of BE and IDLE classesDivyesh Shah2010-03-251-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Even if they are found to be co-operating. The prio_trees do not have any IDLE cfqqs on them. cfq_close_cooperator() is called from cfq_select_queue() and cfq_completed_request(). The latter ensures that the close cooperator code does not get invoked if the current cfqq is of class IDLE but the former doesn't seem to have any such checks. So an IDLE cfqq may get merged with a BE cfqq from the same group which should be avoided.

| * cfq-iosched: Add additional blktrace log messages in CFQ for easier debuggingDivyesh Shah2010-03-251-3/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These have helped us debug some issues we've noticed in earlier IO controller versions and should be useful now as well. The extra logging covers: - idling behavior. Since there are so many conditions based on which we decide to idle or not, this patch adds a log message for some conditions that we've found useful. - workload slices and current prio and workload type Changelog from v1: o moved log message from cfq_set_active_queue() to __cfq_set_active_queue() o changed queue_count to st->count Signed-off-by: Divyesh Shah<dpshah@google.com> Signed-off-by: Jens Axboe <jens.axboe@oracle.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Alex Shi reported a kbuild regression which is about 10% performance lost. He bisected to this commit: 3dde36ddea3e07dd025c4c1ba47edec91606fec0. The reason is cfqq_close() can't find close cooperator. Restoring cfq_rq_close()'s threshold to original value makes the regression go away. Since for_preempt parameter isn't used anymore, this patch deletes it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Up to now, applying the in-core activity-log to the on-disk bitmap did not care for logical_block_size. On logical_block_size != 512 byte, this very likely results in misalligned block access and spurious "io errors". We now simply always submit aligned whole 4k blocks, fixing this for logical block sizes of 512, 1024, 2048 and 4096. For even larger logical block sizes, this won't work.

| | * | | drm/nv50: another dodgy DP hackBen Skeggs2010-04-091-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Allows *some* DP cards to keep working in some corner cases that most people shouldn't hit. I hit it all the time with development, so this can stay for now. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
| | * | | drm/nv50: punt hotplug irq handling out to workqueueBen Skeggs2010-04-094-5/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On DP outputs we'll likely end up running vbios init tables here, which may sleep. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
| | * | | drm/nv50: preserve an unknown SOR_MODECTRL value for DP encodersBen Skeggs2010-04-092-1/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This value interacts with some registers we don't currently know how to program properly ourselves. The default of 5 that we were using matches what the VBIOS on early DP cards do, but later ones use 6, which would cause nouveau to program an incorrect mode on these chips.
