Marek Olšák 75cb00dc0c drm/radeon: allow unaligned shader loads on CIK
Set alignment mode to unaligned on CIK to align with amdgpu.  This is
needed for unaligned loads to work properly in mesa.  The current setting
requires dword alignment.

Add the sysfs entries pp_gfx_power_profile and
pp_compute_power_profile which give user a way to set
power profile through parameters minimum sclk, minimum mclk,
activity threshold, up hysteresis and down hysteresis only
when the entry power_dpm_force_performance_level is in
default value "auto". It is read and write. Example:

echo 500 800 20 0 5 > /sys/class/drm/card0/device/pp_*_power_profile

cat /sys/class/drm/card0/device/pp_*_power_profile
500 800 20 0 5

Note: first parameter is sclk in MHz, second is mclk in MHz,
third is activity threshold in percentage, fourth is up hysteresis
in ms and fifth is down hysteresis in ms.

echo set > /sys/class/drm/card0/device/pp_*_power_profile
To set power profile state if it exists.

echo reset > /sys/class/drm/card0/device/pp_*_power_profile
To restore default state and clear previous setting.

decision on whether to disable the irq (based on there no being no
remaining vblank events, i.e. vblank->refcount == 0) to before we signal
the events, we will only disable the irq on the interrupt after the last
event was signaled. In the normal course of events, this will keep the
vblank irq enabled for the entire flip sequence whereas before it would
flip-flop around every interrupt.

v2: Move the disable_fn() call outside of the vblank_event_lock.

Daniel Vetter 38b6441e4e drm/atomic-helper: Remove the backoff hack from set_config
Another one bites the dust.

Again let's not forget to remove the temporary hidden acquire_ctx
assignment, now that we pass this all around explicitly it can go
away again.

Daniel Vetter a4eff9aa6d drm: Add acquire ctx parameter to ->set_config
Surprisingly a lot of legacy drivers roll their own, for
runtime pm and because vmwgfx.

Also make nouveau's set_config static while at it.

Daniel Vetter 2ceb585a95 drm: Add explicit acquire ctx handling around ->set_config
Just the groundwork to have something to feed into ->set_config.
Again we need a temporary hack to still fill out the legacy
ctx in mode_config.acquire_ctx.
