    drm: Rework vblank-wait handling to allow interrupt reduction.

to stay backwards-compatible with old UMS code that didn't even tell
the kernel when it did a modeset, so that the kernel could
save/restore vblank counters. At worst this means vblanks will be
somewhat funky on a setup that very likely no one still runs.

So let's just nuke it.

Plan B would be to set it unconditionally in drm_vblank_init for kms
drivers, instead of in each driver separately. So if this patch breaks
anything please only restore the hunks in drmP.h and drm_irq.c, plus
add a check for DRIVER_MODESET in drm_vblank_init.

Stumbled over this in a discussion on irc with Chris.

drm/amd: Mark some tables as const

2016-05-05T00:20:00+00:00

This patch marks some compile-time constant tables 'const'.
The tables marked in this patch are the low hanging fruit
where little other changes were necesary to avoid casting
away constness etc. Also mark some tables that are private
to a file as static.

drm/amdgpu: Set vblank_disable_allowed = true

2016-04-01T14:08:34+00:00

Without this, since the conversion from drm_vblank_pre/post_modeset to
drm_vblank_on/off, the vblank interrupt could never be disabled after
userspace triggered enabling it.

drm/amdgpu: add irq domain support

2016-01-11T14:52:57+00:00

Hardware blocks on the GPU like ACP generate interrupts in
the GPU interrupt controller, but are driven by a separate
driver.  Add an irq domain to the GPU driver so that
blocks like ACP can register a Linux interrupt.

drm/amdgpu: Fix max_vblank_count value for current display engines

2015-09-23T21:23:42+00:00

The value was much too low, which could cause the userspace visible
vblank counter to move backwards when the hardware counter wrapped
around.
