2010-09-13sched: Improve latencies under load by decreasing minimum scheduling granularityIngo Molnar1-3/+3
Mathieu reported bad latencies with make -j10 kind of kbuild workloads - which is mostly caused by us scheduling with a too coarse granularity. Reduce the minimum granularity some more, to make sure we can meet the latency target. I got the following results (make -j10 kbuild load, average of 3 runs): vanilla: maximum latency: 38278.9 µs average latency: 7730.1 µs patched: maximum latency: 22702.1 µs average latency: 6684.8 µs Mathieu also measured it: | | * wakeup-latency.c (SIGEV_THREAD) with make -j10 | | - Mainline 2.6.35.2 kernel | | maximum latency: 45762.1 µs | average latency: 7348.6 µs | | - With only Peter's smaller min_gran (shown below): | | maximum latency: 29100.6 µs | average latency: 6684.1 µs | Reported-by: Mathieu Desnoyers <mathieu.desnoyers@efficios.com> Reported-by: Linus Torvalds <torvalds@linux-foundation.org> Acked-by: Mathieu Desnoyers <mathieu.desnoyers@efficios.com> Suggested-by: Peter Zijlstra <a.p.zijlstra@chello.nl> Acked-by: Peter Zijlstra <a.p.zijlstra@chello.nl> LKML-Reference: <AANLkTi=8m4g01wZPacySoF7U0PevTNVgJoZZrHiUD-pN@mail.gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>

2010-09-13drm/radeon/kms: fix the colorbuffer CS checker for r300-r500Marek Olšák1-5/+6
This commit fixes bogus CS rejection if it contains a sequence of the following operations: - Set the color buffer 0. track->cb[i].robj becomes non-NULL. - Render. - Set a larger zbuffer than the previously-set color buffer. - Set a larger scissor area as well. - Set the color channel mask to 0 to do depth-only rendering. - Render. --> rejected, because track->cb[i].robj remained non-NULL, therefore the conditional checking for the color channel mask and friends is not performed, and the larger scissor area causes the rejection. This fixes bugs: - https://bugs.freedesktop.org/show_bug.cgi?id=29762 - https://bugs.freedesktop.org/show_bug.cgi?id=28869 And maybe some others which seem to look the same.

2010-09-13drm/radeon/kms: increase lockup detection interval to 10 sec for r100-r500Marek Olšák1-12/+1
One subtest of mesa/demos/gltestperf takes 9 seconds to complete, so to prevent an unnecessary gpu reset followed by a hardlock, I am increasing the interval to 10 seconds after which a GPU is considered in a locked-up state. This is on RV530. However, with a little slower GPU, we would surpass the interval easily, so this is not a good fix for gltestperf. Nevertheless, this commit also fixes hardlocks in the applications which render at speed of less than 1 frame per second, where the whole frame consists of only one command stream. The game Tiny & Big is an example. This bar is now lowered to 0.1 fps. Now the question comes down to whether we should (often unsuccessfully) reset the GPU at all? Once we have stable enough drivers, we won't have to. Has the time come already? If possible, this commit should go to stable as well.

2010-09-13SUNRPC: Fix the NFSv4 and RPCSEC_GSS Kconfig dependenciesTrond Myklebust2-0/+2
The NFSv4 client's callback server calls svc_gss_principal(), which is defined in the auth_rpcgss.ko The NFSv4 server has the same dependency, and in addition calls svcauth_gss_flavor(), gss_mech_get_by_pseudoflavor(), gss_pseudoflavor_to_service() and gss_mech_put() from the same module. The module auth_rpcgss itself has no dependencies aside from sunrpc, so we only need to select RPCSEC_GSS.

2010-09-13statfs() gives ESTALE errorMenyhart Zoltan1-0/+8
Hi, An NFS client executes a statfs("file", &buff) call. "file" exists / existed, the client has read / written it, but it has already closed it. user_path(pathname, &path) looks up "file" successfully in the directory-cache and restarts the aging timer of the directory-entry. Even if "file" has already been removed from the server, because the lookupcache=positive option I use, keeps the entries valid for a while. nfs_statfs() returns ESTALE if "file" has already been removed from the server. If the user application repeats the statfs("file", &buff) call, we are stuck: "file" remains young forever in the directory-cache.

2010-09-11PM / Hibernate: Avoid hitting OOM during preallocation of memoryRafael J. Wysocki1-20/+65
There is a problem in hibernate_preallocate_memory() that it calls preallocate_image_memory() with an argument that may be greater than the total number of available non-highmem memory pages. If that's the case, the OOM condition is guaranteed to trigger, which in turn can cause significant slowdown to occur during hibernation. To avoid that, make preallocate_image_memory() adjust its argument before calling preallocate_image_pages(), so that the total number of saveable non-highem pages left is not less than the minimum size of a hibernation image. Change hibernate_preallocate_memory() to try to allocate from highmem if the number of pages allocated by preallocate_image_memory() is too low. Modify free_unnecessary_pages() to take all possible memory allocation patterns into account. Reported-by: KOSAKI Motohiro <kosaki.motohiro@jp.fujitsu.com> Signed-off-by: Rafael J.
