The downstream facing port caps in the DPCD can give us a hint as to what kind of display mode the sink can use if it doesn't have an EDID. Use that information to pick a suitable mode. v2: Use Returns: for kdoc (Lyude) Add kdocs for drm_display_mode_from_cea_vic() (Lyude) Signed-off-by:Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200904115354.25336-14-ville.syrjala@linux.intel.comReviewed-by:

DP 1.3 adds some extra control knobs for DP->HDMI protocol conversion. Let's use that to configure the "HDMI mode" (ie. infoframes vs. not) based on the capabilities of the sink. Signed-off-by:

Use the new helpers to extract the TMDS clock limits from the downstream facing port and check them in .mode_valid(). TODO: we should check these in .compute_config() too to eg. determine if we can do deep color on the HDMI side or not Signed-off-by:

Move the downstream facing port dotclock check into a new function (intel_dp_mode_valid_downstream()) so that we have a nice future place where we can collect other related checks. Signed-off-by:

We want to differentiate between the DFP dotclock and TMDS clock limits. Let's convert the current thing to just give us the dotclock limit. v2: Use Returns: for kdoc (Lyude) Fix up nouveau code too Signed-off-by: -

Deal with more cases in drm_dp_downstream_max_bpc(): - DPCD 1.0 -> assume 8bpc for non-DP - DPCD 1.1+ DP (or DP++ with DP sink) -> allow anything - DPCD 1.1+ TMDS -> check the caps, assume 8bpc if the value is crap - anything else -> assume 8bpc v2: Use Returns: for kdoc (Lyude) Signed-off-by:

Stash the downstream facing port max bpc away during intel_dp_set_edid(). We'll soon need the EDID in there so we can't figure this out so easily during .compute_config() anymore. Signed-off-by:

Non-HDMI sinks shouldn't be sent infoframes. Check for that when using LSPCON. FIXME: How do we turn off infoframes once enabled? Do we even have to? Signed-off-by: -

Since we store a pointer to the fake iommu device that is allocated on the stack, as soon as we leave the function it goes out of scope and any future dereference is undefined behaviour. Just in case we may need to look at the fake iommu device after initialiation, move the allocation from the stack into the data.

Just in case the caller passes in 0 for both slow&fast timeouts, make sure we initialise the stack value returned. Add an assert so that we don't make the mistake of passing 0 timeouts for the wait. drivers/gpu/drm/i915/intel_uncore.c:2011 __intel_wait_for_register_fw() error: uninitialized symbol 'reg_value'.

Introduce intel_hpd_hotplug_irqs() as a partner to intel_hpd_enabled_irqs(). There's no need to care about the encoders which we're not exposing, so we can avoid hardcoding the masks in various places. Signed-off-by:

Make a clean split between hpd pins for DDI vs. TC. This matches how the actual hardware is split. And with this we move the DDI/PHY->HPD pin mapping into the encoder init instead of having to remap yet again in the interrupt code. Signed-off-by:

Ville Syrjälä authored
Currently DP/HDMI/DDI encoders init their hpd_pin from the connector init. Let's move it to the encoder init so that we don't need to add platform specific junk to the connector init (which is shared by all g4x+ platforms). Signed-off-by:

Since the display hardware is all there even when INTEL_DISPLAY_ENABLED return false we have to be capable of shutting it down cleanly so as to not anger the hw. To that end let's reduce the effect of !INTEL_DISPLAY_ENABLE to just treating all outputs as disconnected. Should prevent anyone from automagically enabling any of them, while still allowing us to cleanly shut them down. v2: Put the check into the right place for CRT Signed-off-by:

Having a mode where the display hardware is present but we try to pretend it isn't just leads to massive headaches when trying to reason what the fallout might be from skipping some random bits of programming. Let's just neuter INTEL_DISPLAY_ENABLED so that we treat the hardware as fully present, except we just don't register any outputs. That's still rather sketchy if the outputs are already enabled when the driver is loaded. I think the simplest solution would be to probe everything as normal and just return disconnected" from all .detect() hooks. That would avoid anything automagically enabling those outputs, but the driver could then shut things down using the normal codepaths. Signed-off-by:

g4x+ sprites have an extra cdclk limitation listed for RGB formats. For some random reason I chose to use cpp>=4 as the check for that. While that does actually work let's deobfuscate it by checking for !is_yuv instead. I suspect is_yuv didn't exist way back when I originally write the code. Also drop the duplicate comment.

Ville Syrjälä authored
Even if we're not doing downscaling we should account for some of the extra dotclock limitations for g4x+ sprites. In particular we must never exceed the 90% rule, and with RGB that limits actually drops to 80%. So instead of bailing out when upscaling let's clamp the scaling factor appropriately and go through the rest of calculation normally. By luck we already did the full calculations for the 1:1 case.

The CACHE_MODE_0 save/restore was added without explanation in commit 1f84e550 ("drm/i915 more registers for S3 (DSPCLK_GATE_D, CACHE_MODE_0, MI_ARB_STATE)"). If there are any bits we care about those should be set explicitly during some appropriate init function. Let's assume it's all good and just nuke this magic save/restore. Signed-off-by:

Originally added in commit 1f84e550 ("drm/i915 more registers for S3 (DSPCLK_GATE_D, CACHE_MODE_0, MI_ARB_STATE)") to fix some underruns. I suspect that was due to the trickle feed settings getting clobbered during suspend. We've been disabling trickle feed explicitly since commit 20f94967 ("drm/i915: Disable trickle feed via MI_ARB_STATE for the gen4") so this magic save/restore should no longer be needed.

The FBC_CONTROL save restore is there just to preserve the compression interval setting. Since commit a68ce21b ("drm/i915/fbc: Store the fbc1 compression interval in the params") we've been explicitly setting the interval to a specific value, so the sace/restore is now entirely pointless.
