Allows us to mark it static and so forgoe the kerneldoc for it. Note that intel_power_domains_fini is also called from failure paths in the driver load sequence. But the call to runtime_pm_disable for that is harmless since by default runtime pm is already disabled. v2: Augment the commit message as discussed with Imre on irc. Reviewed-by:

- fini goes with init, so call it intel_power_domains_fini. While at it shovel some of the fini code that leaked out of it back in. - give power_enabled functions the verb _is_ to make the meaning clearer. Also use a __ prefix instead of _unlocked to really discourage users. - rename runtime_pm_init/fini to enable/disable since that's what they do. Reviewed-by:

So I think I've spotted a small gap in the frontbuffer tracking while discussing the logic with Paulo on irc: 1. Userspace schedules gpu rendering to the current frontbuffer. This gets tracked in dev_priv->fb_tracking.busy_bits. 2. We pageflip a fully rendered buffer before the frontbuffer rendering completes. 3. The request retiring will never clear busy_bits (since at retire time the old frontbuffer won't have obj->frontbuffer_bits set), so these bits now are stuck until someone again does a bit of frontbuffer tracking. If we clear stale busy_bits in flip_prepare this gap is closed. Reviewed-by:

SKL stage 1 patches still need polish so will likely miss the 3.18 merge window. We've decided to postpone to 3.19 so let's pull this in to make patch merging and conflict handling easier. Signed-off-by: -

Sink crc was implemented based on dp 1.1 spec that had all TEST_SINK bits reserved reading all 0s. But when reviewing my latest changes on sink crc Todd warned me that on new specs we have other valid bits on this reg that we might want to preserve.

In some cases like when PSR just got enabled the panel need more vblank times to calculate CRC. I figured that out with the new PSR test cases facing some cases that I had a green screen but a blank CRC. Even with 2 vblank waits on kernel + 2 vblank waits on test case. So let's give up to 6 vblank wait time. However we now check for TEST_CRC_COUNT that shows when panel finished to calculate CRC and has it ready. v2: Jani pointed out attempts decrements was wrong and should never reach the error condition. And Daniel pointed out that EIO is more appropriated than EGAIN. Also I realized that I have to read test_crc_count after setting test_sink v3: Rebase and adding error message Cc: Todd Previte <tprevite@gmail.com> Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Cc: Jani Nikula <jani.nikula@intel.com> Signed-off-by:

BDW display - DP buffer translation values changed to give better margin. Further change to entry 6; set dword 0 bit 31=1. Both changes were approved already but this one didn't landed BSpec yet this is why it is in a separated patch. Making reviewer's life easier. Also alowing separated tests and any future bisect that might be needed. Reference: Predator r74080 / HSD 4394389 v2: Arthur noticed I was changing the wrong bit.

Let's make sure PSR is propperly disabled before to re-enabled it. According to Spec, after disabled PSR CTL, the Idle state might occur up to 24ms, that is one full frame time (1/refresh rate), plus SRD exit training time (max of 6ms), plus SRD aux channel handshake (max of 1.5ms). So if something went wrong PSR will be disabled until next full enable/disable setup. v2: The 24ms above takes in account 16ms for refresh rate on 60Hz mode. However on low frequency modes this can take longer. So let's use 50ms for safeness. v3: Move wait out of psr.lock critical area.

The sw cache clean on BDW is a tempoorary workaround because we cannot set cache clean on blt ring with risk of hungs. So we are doing the cache clean on sw. However we are doing much more than needed. Not only when using blt ring. So, with this extra w/a we minimize the ammount of cache cleans and call it only on same cases that it was being called on gen7. The traditional FBC Cache clean happens over LRI on BLT ring when there is a frontbuffer touch happening. frontbuffer tracking set fbc_dirty variable to let BLT flush that it must clean FBC cache. fbc.need_sw_cache_clean works in the opposite information direction of ring->fbc_dirty telling software on frontbuffer tracking to perform the cache clean on sw side. v2: Clean it a little bit and fully check for Broadwell instead of gen8. v3: Rebase after frontbuffer organization. v4: Wiggle confused me. So fixing v3! Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Cc: Paulo Zanoni <paulo.r.zanoni@intel.com> Reviewed-by:

The panel has to be reconfigured only when it really loose the power. The traditional enable/disable sequence already take care of this so we can minimize the time spend on every re-enable. Signed-off-by:
