[why] a recent regression has caused us to mistakenly switch RX back to SST mode when there are remaining mst stream enabled to the link. We are missing a condition check for stream count before setting RX back to SST mode. [how] Add stream count check condition back and do some further refactor so the logic is easier to understand to prevent future coding error in this sequence.

[Description] - Single 4K60 playing YUV420 MPO video blocks P-State because the required VRatio for prefetch is too high (luma plane for YUV420 is 1bpe, so swath height is 16 and prefetch requires more lines) - Allow max vratio per plane to be 7.9 for single display YUV420 MPO video cases - Ensure that global vratio prefetch (i.e. total prefetch BW vs. total active bandwidth) does not excited 4.0 Reviewed-by: Nevenko Stupar <Nevenko.Stupar@amd.com> Acked-by: Qingqing Zhuo <qingqing.zhuo@amd.com> Signed-off-by: Alvin Lee <Alvin.Lee2@amd.com> Tested-by: Daniel Wheeler <daniel.wheeler@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

[Why] DOMAIN power gating control is now required to be done via firmware due to interlock with other power features. This is to avoid intermittent issues in the LB memories. [How] If the firmware supports the command then use the new firmware as the sequence can avoid potential display corruption issues. The command will be ignored on firmware that does not support DOMAIN power control and the pipes will remain always on - frequent PG cycling can cause the issue to occur on the old sequence, so we should avoid it.

This reverts commit 3cc67fe1. Some users have reported flickerng with S/G display. We've tried extensively to reproduce and debug the issue on a wide variety of platform configurations (DRAM bandwidth, etc.) and a variety of monitors, but so far have not been able to. We disabled S/G display on a number of platforms to address this but that leads to failure to pin framebuffers errors and blank displays when there is memory pressure or no displays at all on systems with limited carveout (e.g., Chromebooks). We have a parameter to disable this as a debugging option as a way for users to disable this, depending on their use case, and for us to help debug this further. Having this enabled seems like the lesser of to evils.

Currently amdgpu calls drm_sched_fini() from the fence driver sw fini routine - such function is expected to be called only after the respective init function - drm_sched_init() - was executed successfully. Happens that we faced a driver probe failure in the Steam Deck recently, and the function drm_sched_fini() was called even without its counter-part had been previously called, causing the following oops: amdgpu: probe of 0000:04:00.0 failed with error -110 BUG: kernel NULL pointer dereference, address: 0000000000000090 PGD 0 P4D 0 Oops: 0002 [#1] PREEMPT SMP NOPTI CPU: 0 PID: 609 Comm: systemd-udevd Not tainted 6.2.0-rc3-gpiccoli #338 Hardware name: Valve Jupiter/Jupiter, BIOS F7A0113 11/04/2022 RIP: 0010:drm_sched_fini+0x84/0xa0 [gpu_sched] [...] Call Trace: <TASK> amdgpu_fence_driver_sw_fini+0xc8/0xd0 [amdgpu] amdgpu_device_fini_sw+0x2b/0x3b0 [amdgpu] amdgpu_driver_release_kms+0x16/0x30 [amdgpu] devm_drm_dev_init_release+0x49/0x70 [...] To prevent that, check if the drm_sched was properly initialized for a given ring before calling its fini counter-part. Notice ideally we'd use sched.ready for that; such field is set as the latest thing on drm_sched_init(). But amdgpu seems to "override" the meaning of such field - in the above oops for example, it was a GFX ring causing the crash, and the sched.ready field was set to true in the ring init routine, regardless of the state of the DRM scheduler. Hence, we ended-up using sched.ops as per Christian's suggestion [0], and also removed the no_scheduler check [1].

The pid field corresponds to the result of gettid() in userspace. However, userspace cannot reliably attribute PTE events to processes with just the thread id. This patch allows userspace to easily attribute PTE update events to specific processes by comparing this field with the result of getpid(). For attributing events to specific threads, the thread id is also contained in the common fields of each trace event.
