2023-11-06drm/i915: Bump GLK CDCLK frequency when driving multiple pipesVille Syrjälä
On GLK CDCLK frequency needs to be at least 2*96 MHz when accessing the audio hardware. Currently we bump the CDCLK frequency up temporarily (if not high enough already) whenever audio hardware is being accessed, and drop it back down afterwards. With a single active pipe this works just fine as we can switch between all the valid CDCLK frequencies by changing the cd2x divider, which doesn't require a full modeset. However with multiple active pipes the cd2x divider trick no longer works, and thus we end up blinking all displays off and back on. To avoid this let's just bump the CDCLK frequency to >=2*96MHz whenever multiple pipes are active. The downside is slightly higher power consumption, but that seems like an acceptable tradeoff. With a single active pipe we can stick to the current more optiomal (from power comsumption POV) behaviour.

2023-11-06drm/i915/dp_mst: Disable DSC on ICL MST outputsImre Deak
Enabling DSC on ICL MST outputs is broken leading to FIFO pipe / transcoder underruns and blank screen. On TGL+ platforms MST/DSC works - after fixing the known issues in [1] - however to make this work on ICL requires more work. So far DSC on MST probably didn't get enabled for users - due to an issue fixed by [2] - but after fixing that, DSC could get enabled, leading to a blank screen in ICL/MST configurations which do work atm. To prevent this disable MST/DSC on ICL for now.

2023-11-06drm: Do not round to megabytes for greater than 1MiB sizes in fdinfo statsTvrtko Ursulin
It is better not to lose precision and not revert to 1 MiB size granularity for every size greater than 1 MiB. Sizes in KiB should not be so troublesome to read (and in fact machine parsing is I expect the norm here), they align with other api like /proc/meminfo, and they allow writing tests for the interface without having to embed drm.ko implementation knowledge into them. (Like knowing that minimum buffer size one can use for successful verification has to be 1MiB aligned, and on top account for any pre-existing memory utilisation outside of driver's control.) But probably even more importantly I think that it is just better to show the accurate sizes and not arbitrary lose precision for a little bit of a stretched use case of eyeballing fdinfo text directly.
