Previously, drivers supporting vblank interrupt waits would run the interrupt all the time, or all the time that any 3d client was running, preventing the CPU from sleeping for long when the system was otherwise idle. Now, interrupts are disabled any time that no client is waiting on a vblank event. The new method uses vblank counters on the chipsets when the interrupts are turned off, rather than counting interrupts, so that we can continue to present accurate vblank numbers.

Wrap access to task credentials so that they can be separated more easily from the task_struct during the introduction of COW creds. Change most current->(|e|s|fs)[ug]id to current_(|e|s|fs)[ug]id(). Change some task->e?[ug]id to task_e?[ug]id(). In some places it makes more sense to use RCU directly rather than a convenient wrapper; these will be addressed by later patches. Signed-off-by:

[Patch against drm-next. Consider this a trial balloon for our new Linux development model.] This is a big chunk of code. Separating it out makes it easier to change without churn on the main i915_drv.c file (and there will be churn as we fix bugs and add things like kernel mode setting). Also makes it easier to share this file with BSD. Signed-off-by:

Eric Anholt authored
Previous attempts at interrupt mitigation had been foiled by i915_wait_irq's failure to update the sarea seqno value when the status page indicated that the seqno had already been passed. MSI support has been seen to cut CPU costs by up to 40% in some workloads by avoiding other expensive interrupt handlers for frequent graphics interrupts. Signed-off-by:

Fix the SIS DRM memory allocator if the SIS FB built as a module. The SIS DRM code initialises the mm allocation hooks, but _only_ if the SIS FB is not built as a module because it depends on CONFIG_FB_SIS, and that's unset if the SIS FB is not built in. It must check CONFIG_FB_SIS_MODULE as well. Signed-off-by:

If this triggers its bad, however some machines seem to have been triggering it for ages and we didn't know until we added the debug. So downgrade the debug now so people don't call this a regression. Signed-off-by:

There is a problem with debugging the X server and gdb crashes in the xkb startup code. This avoids the problem by allowing the master process to get signals. It should be safe as the signal blocker is mainly so that you can Ctrl-Z a 3D application without locking up the whole box. Ctrl-Z the X server isn't something many people do. Signed-off-by: -

This makes our handling of cliprects sane. drm_clip_rect always has exclusiv bottom-right corners, but the hardware expects inclusive bottom-right corner so we adjust this here. This complements Michel Daenzer's commit 57aea290e1e0a26d1e74df6cff777eb9f03 to Mesa. See also http://bugs.freedesktop.org/show_bug.cgi?id=16123 Signed-off-by:

DRAW_INDEX writes a vertex count to VAP_VF_CNTL. Docs say that behaviour is undefined (i.e. lockups happen) when this write is not followed by the right number of vertex indices. Thus we used to do the wrong thing when drawing across many cliprects was necessary, because we emitted a sequence DRAW_INDEX, DRAW_INDEX, INDX_BUFFER, INDX_BUFFER instead of DRAW_INDEX, INDX_BUFFER, DRAW_INDEX, INDX_BUFFER The latter is what we're doing now and which ought to be correct.

This patch should fix hard lockup and convert them in softlockup (ie you can ssh the box but the gpu is busted and we are waiting in loop for it to come back to reason). Signed-off-by:

Some module parameters with only one line have the '\n' at the end of the description. This is not needed nor wanted as after the description the type (i.e. int) is followed by a newline. Some modules contain a multi-line description, these are not affected by this patch. Signed-off-by:

With the coming of kernel based modesetting and the memory manager stuff, the everything in one directory approach was getting very ugly and starting to be unmanageable. This restructures the drm along the lines of other kernel components. It creates a drivers/gpu/drm directory and moves the hw drivers into subdirectores. It moves the includes into an include/drm, and sets up the unifdef for the userspace headers we should be exporting. Signed-off-by:
