Add new file intel_modeset_verify.c for high level modeset verification code to declutter intel_display.h. The new file is supposed to be about crtc/encoder/connector verification; the state verification for very specific functionality such as plls or wm should be placed next to the code it verifies. Fix some minor checkpatch issues while at it. v2: Rebase Signed-off-by:

Abstract the bit extraction from the VBT per-panel bitfields slightly. Signed-off-by:
-
Ville Syrjälä authored
Older VBTs don't have all the stuff we've defined for the LVDS options block (40). In particular we're currently parsing the DPS panel type bits even though they may not exist, which could mean we end up flagging the machine as supporting static DRRS when the VBT declared no such thing. We don't actually have a clear idea which VBT versions have which bits so we rely on the block size instead. Here's a quick list from my VBT stash: mgm version 108 -> 4 bytes alv version 120 -> 4 bytes cst version 134 -> 14 bytes pnv version 144 -> 14 bytes cl version 142 -> 16 bytes ctg version 155 -> 24 bytes Signed-off-by:

Parsing the panel_type is a bit special and should be done before we parse anything else potentially panel-specific from the VBT. So move it out from parse_panel_options(). It doesn't neet to be there anyway since it'll do its own LVDS options block lookup. Signed-off-by:

The WARN shouldn't have been added yet. For the moment the clock that gets passed here is just what the user has requested (via the modeline) and may not be exactly what iCLKIP can generate. Later on the plan is to change things so that we already get passed the exact clock here, at which point the WARN should be reintroduced.

Connector polling is waking up the polled device. Polling is unnecessary if our device is known to not have display. Fix this and save some power by disabling starting connector polling when we are having headless sku.

Commit 3cf05076 ("drm/i915/bios: Split VBT data into per-panel vs. global parts") cause PSR to be disabled when enable_psr has the default value and there is at least one DP port that do not supports PSR. That was happening because intel_psr_init() is called for every DP port and then enable_psr is globaly set to 0 based on the PSR support of the DP port. Here dropping the enable_psr overwritten and using the VBT PSR value when enable_psr is set as default.

Ville Syrjälä authored
We're not parsing the 5.4 Gbps value for the old eDP fast link training link rate, nor are we parsing the new fast link training link rate field. Remedy both. Also we'll now use the actual link rate instead of the DPCD BW register value. Note that we're not even using this information for anything currently, so should perhaps just nuke it all unless someone is planning on implementing fast link training finally... v2: Stop using the DPCD BW values (Jani) *20 instead of *2 to get the rate in correct units (Jani) Cc: Jani Nikula <jani.nikula@intel.com> Signed-off-by: -

We'll need to know the VBT panel_type before we can determine the maximum link rate for eDP. To that end move intel_dp_set_source_rates() & co. to be called after the per-panel VBT parsing has been done. intel_dp_mst_encoder_init() depends on the source rates so we'll have to do it a bit later as well. v2: Fix the intel_dp_mst_encoder_init() oops Reviewed-by: Jani Nikula <jani.nikula@intel.com> #v1 Signed-off-by:

The intel_dp_dsc_get_output_bpp() function outputs two lines of unconditional logs, which was okay when it was called only once. But now, we also call this function from intel_dp_mode_valid(), which is in turn called for every mode we need to validate. This causes a lot of useless noise. Remove the unconditional prints to avoid spamming the logs. Also remove one more print that is not unconditional, but is related. Signed-off-by:

Some machines declare DRRS type = seamless, DRRS = no, DMRRS = yes. I *think* DMRRS stands for "dynamcic media refresh rate", and I suspect the way it's meant to work is that it lets the driver switch refresh rates to match the frame rate for media playback. Obviously for us all that kind of policy stuff is entirely up to userspace, so the only thing we may do is make the extra refresh rate(s) available. So let's treat this case as just static DRRS for now. In the future We might want to differentiate the "seamless w/ downclocking" vs. "seamless w/o downclocking" cases so that we could do seamless refresh rate changes for systems that only claim to support DMRRS.

It seem that when dealing with VRR capable eDP panels we need to accept fixed modes with variable vblank length (which is what VRR varies dynamically). Typically the preferred mode seems to be a non-VRR more (lowish dotclock/refresh rate + short vblank). We also have examples where it looks like even the hblank length is a bit different between the preferred mode vs. VRR mode(s). So let's just accept anything that has matching hdisp+vdisp+flags. v2: Document that is_alt_drrs_mode() is a subset of is_alt_vrr_mode() (Jani) Closes: https://gitlab.freedesktop.org/drm/intel/-/issues/125Reviewed-by:
