The register can house two different swing marging/deemph settings at once. However only one gets used based on some other bits. Make sure we set those bits correctly to make the hardware use the settings we provided. Signed-off-by:

This seems to have been accidentally lost in commit be62acb4 Author: Mika Kuoppala <mika.kuoppala@linux.intel.com> Date: Fri Aug 30 16:19:28 2013 +0300 drm/i915: ban badly behaving contexts Without this real gpu hangs only log output at info level, which gets filtered away by piglit's testrunner. v2: Tune down to notice level. Note that we need to add drm/i915 so that at least the automatic igt dmesg filtering still picks it up. v3: git add and lack of coffee don't mix well. v4: Message is in between hw and sw reset, so switch verb to continuous form. v5: Use i915_stop_rings_allow_warn for consistency. For Chris' case of injecting lots of hangs I guess we need to revamp this all anyway when merging. For now this should plug the regression for piglit testing mesa. v6: Make it compile (Mika).

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:

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:

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:
