2023-06-07drm/i915: store the peak bw per QGV pointVinod Govindapillai2-2/+8
In MTL onwards, pcode locks the GV point based on the peak BW of a QGV point.

Caching the has_audio in struct drm_dp_mst_port seems odd, and oddly placed. Defer audio handling to drivers, and use the info from the connector display info. i915 was the only one using it anyway.

2023-05-26drm/i915: Implement CTM property support for VLVVille Syrjälä5-4/+198
VLV has a so called "wide gamut color correction" unit (WGC). What it is is a 3x3 matrix similar to the later CHV CGM CSC, with less precisions/range. In fact CHV also has the WGC but using it there doesn't really make sense when you have the superior CGM CSC around. Hook up the necessary stuff to expose the WGC as the CTM crtc property. One additional crazy idea that came to mind would be to use the WGC as an output CSC on CHV for YCbCr output. But it would be incompatible with the legacy LUT usage. In fact since the WGC lacks post-offsets we'd probably have to use the legacy LUT to do that final part of the RGB->YCbCr conversion. Sounds doable, but perhaps not worth the hassle.

2023-05-26drm/i915: Always enable CGM CSC on CHVVille Syrjälä1-2/+19
On CHV toggling the CGM CSC on/off while the pipe is running leads to underruns. Looks like we'd have to do the toggling strictly inside the start_of_vblank-frame_start window to avoid this, but that window is less than a scanline so there's no way we can guarantee hitting it. As a workaround let's just leave the CGM CSC permanently enabled. Fortunately the CGM gamma/degamma units don't seem to suffer from this malady. I also tried turning off CGM unit clock gating, but that did not help.

The ilk/snb code is internally fully capable of handling the CTM property, so expose it. Note that we still choose not to expose DEGAMMA_LUT though. The hardware is capable if degamma or gamma, but not both simultanously due to lack of the split gamma mode. Exposing both LUTs might encourage userspace to try enabling both at the same time.

2023-05-26drm/i915: Fix clang -Wimplicit-fallthrough in intel_async_flip_check_hw()Nathan Chancellor1-0/+1
Clang warns: drivers/gpu/drm/i915/display/intel_display.c:6012:3: error: unannotated fall-through between switch labels [-Werror,-Wimplicit-fallthrough] case I915_FORMAT_MOD_X_TILED: ^ drivers/gpu/drm/i915/display/intel_display.c:6012:3: note: insert 'break;' to avoid fall-through case I915_FORMAT_MOD_X_TILED: ^ break; 1 error generated. Clang is a little more pedantic than GCC, which does not warn when falling through to a case that is just break or return. Clang's version is more in line with the kernel's own stance in deprecated.rst, which states that all switch/case blocks must end in either break, fallthrough, continue, goto, or return. Add the missing break to silence the warning.
