2018-11-21drm/i915: Add rotation readout for plane initial configVille Syrjälä2-0/+32
If we need to force a full plane update before userspace/fbdev have given us a proper plane state we should try to maintain the current plane state as much as possible (apart from the parts of the state we're trying to fix up with the plane update). To that end add basic readout for the plane rotation and maintain it during the initial fb takeover.

2018-11-21drm/i915: Force a LUT update in intel_initial_commit()Ville Syrjälä1-0/+8
If we force a plane update to fix up our half populated plane state we'll also force on the pipe gamma for the plane (since we always enable pipe gamma currently). If the BIOS hasn't programmed a sensible LUT into the hardware this will cause the image to become corrupted. Typical symptoms are a purple/yellow/etc. flash when the driver loads. To avoid this let's program something sensible into the LUT when we do the plane update. In the future I plan to add proper plane gamma enable readout so this is just a temporary measure.

2018-11-21drm/i915: Make CHICKEN_TRANS reg not depend on enum valueImre Deak3-17/+52
Depending on the transcoder enum values to translate from transcoder to the corresponding CHICKEN_TRANS register can easily break if we add a new transcoder. Add an explicit mapping instead, by using helpers to look up the register instance either by transcoder or port (since unconveniently the registers have both port and transcoder specific bits). While at it also check for the correctness of GEN, port, transcoder. I wasn't sure if psr2_enabled can only be set for GEN9+, but that seems to be the case indeed (see setting of sink_psr2_support in intel_psr_init_dpcd()). v2 (Ville): - Make gen9_chicken_trans_reg() internal to intel_psr.c. - s/trans/cpu_transcoder/ Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: Lucas De Marchi <lucas.demarchi@intel.com> Cc: Mika Kahola <mika.kahola@intel.com> Signed-off-by: Imre Deak <imre.deak@intel.com> Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20181119180021.370-1-imre.deak@intel.com

2018-11-16drm/i915: Disable LP3 watermarks on all SNB machinesVille Syrjälä1-1/+40
I have a Thinkpad X220 Tablet in my hands that is losing vblank interrupts whenever LP3 watermarks are used. If I nudge the latency value written to the WM3 register just by one in either direction the problem disappears. That to me suggests that the punit will not enter the corrsponding powersave mode (MPLL shutdown IIRC) unless the latency value in the register matches exactly what we read from SSKPD. Ie. it's not really a latency value but rather just a cookie by which the punit can identify the desired power saving state. On HSW/BDW this was changed such that we actually just write the WM level number into those bits, which makes much more sense given the observed behaviour. We could try to handle this by disallowing LP3 watermarks only when vblank interrupts are enabled but we'd first have to prove that only vblank interrupts are affected, which seems unlikely. Also we can't grab the wm mutex from the vblank enable/disable hooks because those are called with various spinlocks held. Thus we'd have to redesigne the watermark locking. So to play it safe and keep the code simple we simply disable LP3 watermarks on all SNB machines. To do that we simply zero out the latency values for watermark level 3, and we adjust the watermark computation to check for that. The behaviour now matches that of the g4x/vlv/skl wm code in the presence of a zeroed latency value. v2: s/USHRT_MAX/U32_MAX/ for consistency with the types (Chris) Cc: stable@vger.kernel.org Cc: Chris Wilson <chris@chris-wilson.co.uk> Acked-by: Chris Wilson <chris@chris-wilson.co.uk> Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=101269 Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=103713 Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20181114173440.6730-1-ville.syrjala@linux.intel.com
