2019-03-20drm/i915: Keep plane watermarks enabled more aggressivelyVille Syrjälä
Currently we disable all the watermarks above the selected max level for every plane. That would mean that the cursor's watermarks may also get modified when another plane causes the selected max watermark level to change. That is not so great as we would like to keep the cursor as indepenedent as possible to avoid having to throttle it in resposne to other plane activity. To avoid that let's keep the watermarks enabled even for levels above the max selected watermark level, iff the plane has enough ddb for that particular level. This way the cursor's enabled watermarks only depend on the cursor itself. This is safe because the hardware will never choose to use a watermark level unless all enabled planes have also enabled that level.

2019-03-20drm/i915: Allocate enough DDB for the cursorVille Syrjälä
Currently we just assume that 32 or 8 blocks of ddb is sufficient for the cursor. The 32 might be, but the 8 is certainly not. The minimum we need is at least what level 0 watermarks need, but that is a bit restrictive, so instead let's calculate what level 7 would need for a 256x256 cursor. We'll use that to determine the fixed ddb allocation for the cursor. This way the cursor will never be responsible for missing out on deeper power saving states. v2: Loop to make sure this works even if some wm levels are totally disabled (latency==0) Cc: Neel Desai <neel.desai@intel.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Matt Roper <matthew.d.roper@intel.com> #v1 Link: https://patchwork.freedesktop.org/patch/msgid/20190319160311.23529-1-ville.syrjala@linux.intel.com

skl_compute_plane_wm() doesn't actually need the plane state. While it would make logically sense to pass it, we shall need to reuse skl_compute_plane_wm() to compute the minimum ddb allocation for the cursor before the cursor may be enabled. Thus we can't rely on the plane state. The alternative would be to duplicate a lot of the wm calculations for the cursor ddb allocation case, which doens't appeal to me.

2019-03-20drm/i915/selftests: add test to verify get/put fw domainsDaniele Ceraolo Spurio
Exercise acquiring and releasing forcewake around register reads. In order to read a register behind a GT powerwell, we need to instruct that powerwell to wake up using a forcewake. When we no longer require the GT powerwell, we tell the GT to release our forcewake. Inside the forcewake, the register read should work but outside it should just return garbage, 0 being the most common garbage. Thus we can detect when we are inside and outside of the forcewake with just a simple register read, and so can verify that the GT powerwell is released when we say so. v2: Picking the right forcewaked register to return 0 outside of forcewake is an art.

2019-03-19drm/i915: Fix PSR2 selective update corruption after PSR1 setupJosé Roberto de Souza
There is probably a issue in DMC firmwares(icl_dmc_ver1_07.bin and kbl_dmc_ver1_04.bin at least) that causes PSR2 SU to fail after exiting DC6 if EDP_PSR_TP1_TP3_SEL is kept in PSR_CTL, so for now lets workaround the issue by cleaning PSR_CTL before enable PSR2. v2: - Updated commit description and comment to state that it may be a DMC firmware issue (Rodrigo) - No need to RMW, let's write 0 to PSR_CTL(Dhinakaran) Cc: Dhinakaran Pandiyan <dhinakaran.pandiyan@intel.com> Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Signed-off-by: José Roberto de Souza <jose.souza@intel.com> Reviewed-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Reviewed-by: Dhinakaran Pandiyan <dhinakaran.pandiyan@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190314230113.6571-1-jose.souza@intel.com

This reverts commit 8466cc61da89d33441e0d7a98de1ba98697cd465. It can trigger a reference counter bug in TTM. Need to investigate further, but for now revert the offending change.

2019-03-19drm/i915: Remove the fragile array index -> link rate mappingVille Syrjälä
Rather than try to maintain some magic relationship between the link rates and the index into the wrpll params array let's just store the link rate in the array itself. Much less fragile.

We already have the code to calculate the WRPLL output clock from the register values, but for some reason we're only using it for HDMI and not DP. Throw out the inflexible DP DPLL table lookup and just call the HDMI code which decodes the actual register values.
