I don't see any problem with moving those calls outside the lock, which is what this patch does.

2020-08-24drm/amd/display: Reject overlay plane configurations in multi-display scenariosNicholas Kazlauskas1-0/+8
[Why] These aren't stable on some platform configurations when driving multiple displays, especially on higher resolution. In particular the delay in asserting p-state and validating from x86 outweights any power or performance benefit from the hardware composition. Under some configurations this will manifest itself as extreme stutter or unresponsiveness especially when combined with cursor movement. [How] Disable these for now. Exposing overlays to userspace doesn't guarantee that they'll be able to use them in any and all configurations and it's part of the DRM contract to have userspace gracefully handle validation failures when they occur. Valdiation occurs as part of DC and this in particular affects RV, so disable this in dcn10_global_validation.

2020-08-24drm/etnaviv: always start/stop scheduler in timeout processingLucas Stach1-5/+6
The drm scheduler currently expects that the stop/start sequence is always executed in the timeout handling, as the job at the head of the hardware execution list is always removed from the ring mirror before the driver function is called and only inserted back into the list when starting the scheduler. This adds some unnecessary overhead if the timeout handler determines that the GPU is still executing jobs normally and just wished to extend the timeout, but a better solution requires a major rearchitecture of the scheduler, which is not applicable as a fix.

This patch implements WA for AM65xx erratum i2000, which causes YUV formats to show wrong colors. An earlier patch removed a partial WA: a8d9d7da1546349f18eb2d6b6b3a04bdeb38719d ("drm/tidss: remove AM65x PG1 YUV erratum code") The patch explains the reasoning for removal. The change in plans has been that it has become clear that there are and will be users for PG1 SoCs and as such it's good to implement the WA for PG1s. This patch adds the WA back so that it is only used on SR1.0 (which is the new name for PG1). The previous WA code didn't check the SoC revision, which this patch does.

Finalize he conversion of GMA500 to use only GPIO descriptors. The GPIO look-up-table is associated with the device directly in the GMA500 Medfield chip driver since no explicit platform type device (such as in x86/platform/intel-mid) exists: the GMA500 probes directly from the PCI device. Apparently GPIOs 128 and 34 are used on all of these so just go ahead and register those for resetting the DSI pipes.

2020-08-19drm/i915/tgl: Make sure TC-cold is blocked before enabling TC AUX power wellsImre Deak1-6/+6
The dependency between power wells is determined by the ordering of the power well list: when enabling the power wells for a domain, this happens walking the power well list forward, while disabling them happens in the reverse direction. Accordingly a power well on the list must follow any other power well it depends on. Since the TC AUX power wells depend on TC-cold being blocked, move the TC-cold off power well before all AUX power wells.

2020-08-19drm/i915/selftests: Avoid passing a random 0 into ilog2George Spelvin1-8/+10
igt_mm_config() calls ilog2() on the (pseudo)random 21-bit number s>>12. Once in 2 million seeds, this is zero and ilog2 summons the nasal demons. There was an attempt to handle this case with a max(), but that's too late; ms could already be something bizarre. Given that the low 12 bits of s and ms are always zero, it's a lot simpler just to divide them by 4096, then everything fits into 32 bits, and we can easily generate a random number 1 <= s <= 0x1fffff.
