I'm not sure whether this patch comes in too late, but it would be good to have it in. It stabilizes command submission in case of command buffer errors. * 'vmwgfx-fixes-4.3' of git://people.freedesktop.org/~thomash/linux: drm/vmwgfx: Stabilize the command buffer submission code

drm/vmwgfx: Stabilize the command buffer submission code

2015-10-21T19:31:49+00:00

This commit addresses some stability problems with the command buffer submission code recently introduced: 1) Make the vmw_cmdbuf_man_process() function handle reruns internally to avoid losing interrupts if the caller forgets to rerun on -EAGAIN. 2) Handle default command buffer allocations using inline command buffers. This avoids rare allocation deadlocks. 3) In case of command buffer errors we might lose fence submissions. Therefore send a new fence after each command buffer error. This will help avoid lengthy fence waits. Signed-off-by: Thomas Hellstrom Reviewed-by: Sinclair Yeh

drm/vmwgfx: Fix a command submission hang regression

2015-09-30T12:50:37+00:00

When we're out of command buffer space, we turn on the command buffer processed irq without re-checking for finished command buffers afterwards. This might lead to a missed irq and the command submission process waiting forever for space. Fix this by rerunning the command buffer submission handler whenever we're out of command space. This ensures both that we don't needlessly turn on the irq, and that if we decide to turn on the irq, we recheck for finished command buffers before going to sleep.
