2021-02-19drm/radeon/nislands_smc.h: Replace one-element array with flexible-array ↵Gustavo A. R. Silva1-5/+5
member in struct NISLANDS_SMC_SWSTATE There is a regular need in the kernel to provide a way to declare having a dynamically sized set of trailing elements in a structure.

2021-02-18drm/i915: Nuke INTEL_OUTPUT_FORMAT_INVALIDVille Syrjälä3-4/+1
We tend to use output_format!=RGB as a shorthand for YCbCr, but this fails if we have a disabled crtc where output_format==INVALID. We're now getting some fail from intel_color_check() when we have: hw.enable==false hw.ctm!=NULL output_format==INVALID Let's avoid that by throwing INTEL_OUTPUT_FORMAT_INVALID to the dumpster, and thus everything defaults to RGB when the crtc is disabled. This does beg the deeper question of how much of the state should we in fact be validating when hw/uapi.enable==false. And should we even be doing the uapi->hw copy when uapi.enable==false? So far I've not been able to come up with satisfactory answers for myself, so I'm putting it off for the moment.

It's possible to modeset a connector/mst port that has a 0 full_pbn value: if the sink on the port deasserts its HPD and a branch device reports this via a CSN with the port's ddps=0 and pdt!=NONE the driver clears full_pbn, but the corresponding connector can be still modesetted. This happened on a DELL U2719D monitor as the branch device and an LG 27UL650-W daisy-chained to it, the LG monitor generating a long HPD pulse (doing this for some reason always when waking up from some power saving state).

The first was due to DECLARE_WAIT_QUEUE_HEAD_ONSTACK, which was fixed in LLVM 9.0.0. The second was in busywait_stop, which was fixed in LLVM 10.0.0 (issue 415). The kernel's minimum version for LLVM is 10.0.1 so this warning can be safely enabled, where it has already caught a couple bugs.

2021-02-17drm/i915: Disallow plane x+w>stride on ilk+ with X-tilingVille Syrjälä3-6/+39
ilk+ planes get notably unhappy when the plane x+w exceeds the stride. This wasn't a problem previously because we always aligned SURF to the closest tile boundary so the x offset never got particularly large. But now with async flips we have to align to 256KiB instead and thus this becomes a real issue. On ilk/snb/ivb it looks like the accesses just wrap early to the next tile row when scanout goes past the SURF+n*stride boundary, hsw/bdw suffer more heavily and start to underrun constantly. i965/g4x appear to be immune. vlv/chv I've not yet checked. Let's borrow another trick from the skl+ code and search backwards for a better SURF offset in the hopes of getting the x offset below the limit. IIRC when I ran into a similar issue on skl years ago it was causing the hardware to fall over pretty hard as well. And let's be consistent and include i965/g4x in the check as well, just in case I just got super lucky somehow when I wasn't able to reproduce the issue. Not that it really matters since we still use 4k SURF alignment for i965/g4x anyway.

2021-02-16drm/i915: Use .disable_clock() for pll sanitationVille Syrjälä2-90/+3
Instead of every new platform having yet another masive copy of the whole PLL sanitation code, let's just reuse the .disable_clock() hook for this purpose. We do need to plug this into the ICL+ DSI code for that, but fortunately it already has a suitable function we can use. We do lose the debug message though on account of not bothering to check if the clock is actually enabled or not before turning it off. We could introduce yet another vfunc to query the current state, but not sure it's worth the hassle?

The other DDI .enable_clock() functions are trying to protect us against pll==NULL.
