2023-02-24drm/i915/psr: Use calculated io and fast wake linesJouni Högander2-17/+63
Currently we are using hardcoded 7 for io and fast wake lines. According to Bspec io and fast wake times are both 42us for DISPLAY_VER >= 12 and 50us and 32us for older platforms. Calculate line counts for these and configure them into PSR2_CTL accordingly Use 45 us for the fast wake calculation as 42 seems to be too tight based on testing.

2023-02-23drm/i915: Mask page table errors on gen2/3 with FBCVille Syrjälä1-2/+20
FBC on gen2/3 seems to trigger page table errors. No visual artifacts are visible, and essentially the same FBC code works on gen4 so these seem entirely spurious. There are also hints in gen3 bspec indicating that certain bits in PGTBL_ER are just not wired up correctly in the hardware. Ideally we'd want to mask out only the bogus bits, but sadly there is no mask for PGTBL_ER, and instead we are forced to mask out all page table errors via EMR :( Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20230125185234.21599-6-ville.syrjala@linux.intel.com Reviewed-by: Vinod Govindapillai <vinod.govindapillai@intel.com>

2023-02-23drm/i915: Mark FIFO underrun disabled earlierVille Syrjälä4-18/+32
At least on some platforms (tested on ctg) the way vgacon does screen blanking seems to flag constant FIFO underruns, which means we have to be prepared for them while the driver is loading. Currently there is a time window between drm_crtc_init() and intel_sanitize_fifo_underrun_reporting() during which FIFO underrun reporting is in fact marked as enabled. Thus we may end up mistakenly detecting these bogus underruns during driver init. Close the race by marking FIFO underrun reporting as disabled prior to even registering the crtc. intel_sanitize_fifo_underrun_reporting()/etc. will re-enable it later if needed.

2023-02-23drm/i915/audio: Track audio state per-transcoderVille Syrjälä4-50/+48
The audio logic lives in the transcoder rather than the pipe, so start tracking it like that. This is only really important for bigjoiner cases where tracking by pipe doesn't work at all since intel_audio_codec_{enable,disable}() won't even be called for the slave pipe. This means the state checker won't find the ELD for the slave pipe and gets upset. The PD->has_audio readout does currently work since that gets read out from the same transcoder for both pipes. For other cases this doesn't actually matter since it's only the normal pipe transcoders that are audio capable, whereas the more special transcoders (EDP/DSI) are not. v2: Fix kernel docs Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20230222151454.24888-1-ville.syrjala@linux.intel.com Reviewed-by: Uma Shankar <uma.shankar@intel.com> Closes: https://gitlab.freedesktop.org/drm/intel/-/issues/8222

Instead we must now use the new TRANS_SET_CONTEXT_LATENCY register. Program it accordingly. And since VBLANK.VBLANK_START is no longer used by the hardware on ADL+ let's just zero it out to make it stand out in register dumps.

Rename PIPECONF to TRANSCONF to make it clear what it actually applies to. While the usual convention is to pick the earliers name I think in this case it's more clear to use the later name. Especially as even the register offset is in the wrong range (0x70000 vs. 0x60000) and thus makes it look like this is per-pipe. There is one place in gvt that's doing something with TRANSCONF while iterating with for_each_pipe(). So that might not be doing the right thing for TRANSCODER_EDP, dunno.

Name the CPU transcoder timing registers TRANS_FOO rather than just FOO. This is the modern name, after the pipe/transcoder split happened. Makes it a bit more obvious whether you pass in a pipe or a transcoder. PIPESRC is a bit special as it's a pipe register, even though it lives in the transcoder registers range (0x60000 instead of 0x70000). And BCLRPAT I suppose is a transcoder register (since it has something to do with the timing generator), but it doesn't even exist after gen4 so I left it to use the only name it ever had in bspec.

2023-02-16drm/i915/wm: remove ILK+ nop funcs fallbackJani Nikula1-13/+1
Disabling ILK+ watermarks on failure to read the watermark levels dates back to 2010 and commit 7f8a85698f5c ("drm/i915: Add the support of memory self-refresh on Ironlake"), with no explanations, and it's been copied and modified from that ever since. Finally drop it. If the value are actually zero, the ilk_compute_*_wm() functions should handle it gracefully.
