[Why] When enabling a DisplayPort stream: - Optionally reducing link bandwidth between failed link training attempts should progressively relax training requirements. - Abandoning link training altogether if a sink is unplugged should avoid unnecessary training attempts. [How] - Add fallback parameter to DP link training function and reduce link bandwidth between failed training attempts as long as stream bandwidth requirements are met. - Add training status for sink unplug and abort training when this status is reported.

Rename, ras_hw_supported --> ras_hw_enabled, and ras_features --> ras_enabled, to show that ras_enabled is a subset of ras_hw_enabled, which itself is a subset of the ASIC capability.

Move ras_hw_supported into struct amdgpu_dev. The dependency is: struct amdgpu_ras <== struct amdgpu_dev <== ASIC, read as "struct amdgpu_ras depends on struct amdgpu_dev, which depends on the hardware." This can be loosely understood as, "if RAS is supported, which is property of the ASIC (struct amdgpu_dev), then we can access struct amdgpu_ras." v2: Fix a typo: must binary AND in ternary cond in amdgpu_ras.c Cc: Alexander Deucher <Alexander.Deucher@amd.com> Cc: John Clements <john.clements@amd.com> Cc: Hawking Zhang <Hawking.Zhang@amd.com> Signed-off-by: -

Remove redundant ras->supported, as this value is also stored in adev->ras_features. Use adev->ras_features, as that supercedes "ras", since the latter is its member. The dependency goes like this: ras <== adev->ras_features <== hw_supported, and is read as "ras depends on ras_features, which depends on hw_supported." The arrows show the flow of information, i.e. the dependency update. "hw_supported" should also live in "adev".

The builtin size check isn't really the right thing for AMD modifiers due to a couple of reasons: 1) In the format structs we don't do set any of the tilesize / blocks etc. to avoid having format arrays per modifier/GPU 2) The pitch on the main plane is pixel_pitch * bytes_per_pixel even for tiled ... 3) The pitch for the DCC planes is really the pixel pitch of the main surface that would be covered by it ... Note that we only handle GFX9+ case but we do this after converting the implicit modifier to an explicit modifier, so on GFX9+ all framebuffers should be checked here. There is a TODO about DCC alignment, but it isn't worse than before and I'd need to dig a bunch into the specifics. Getting this out in a reasonable timeframe to make sure it gets the appropriate testing seemed more important. Finally as I've found that debugging addfb2 failures is a pita I was generous adding explicit error messages to every failure case.

Add emit mem sync callback for sdma_v5_0 In amdgpu sync object test, three threads created jobs to send GFX IB and SDMA IB in sequence. After the first GFX thread joined, sometimes the third thread will reuse the same physical page to store the SDMA IB. There will be a risk that SDMA will read GFX IB in the previous physical page. So it's better to flush the cache before commit sdma IB. Acked-by:
