drm/amdgpu: throttle buffer migrations at CS using a fixed MBps limit (v2) The old mechanism used a per-submission limit that didn't take previous submissions within the same time frame into account. It also filled VRAM slowly when VRAM usage dropped due to a big eviction or buffer deallocation. This new method establishes a configurable MBps limit that is obeyed when VRAM usage is very high. When VRAM usage is not very high, it gives the driver the freedom to fill it quickly. The result is more consistent performance. It can't keep the BO move rate low if lots of evictions are happening due to VRAM fragmentation, or if a big buffer is being migrated. The amdgpu.moverate parameter can be used to set a non-default limit. Measurements can be done to find out which amdgpu.moverate setting gives the best results. Mainly APUs and cards with small VRAM will benefit from this. For F1 2015, anything with 2 GB VRAM or less will benefit. Some benchmark results - F1 2015 (Tonga 2GB): Limit MinFPS AvgFPS Old code: 14 32.6 128 MB/s: 28 41 64 MB/s: 15.5 43 32 MB/s: 28.7 43.4 8 MB/s: 27.8 44.4 8 MB/s: 21.9 42.8 (different run) Random drops in Min FPS can still occur (due to fragmented VRAM?), but the average FPS is much better. 8 MB/s is probably a good limit for this game & the current VRAM management.

drm/vblank: drop the mode argument from drm_calc_vbltimestamp_from_scanoutpos If we restrict this helper to only kms drivers (which is the case) we can look up the correct mode easily ourselves. But it's a bit tricky: - All legacy drivers look at crtc->hwmode. But that is updated already at the beginning of the modeset helper, which means when we disable a pipe. Hence the final timestamps might be a bit off. But since this is an existing bug I'm not going to change it, but just try to be bug-for-bug compatible with the current code. This only applies to radeon&amdgpu. - i915 tries to get it perfect by updating crtc->hwmode when the pipe is off (i.e. vblank->enabled = false). - All other atomic drivers look at crtc->state->adjusted_mode. Those that look at state->requested_mode simply don't adjust their mode, so it's the same. That has two problems: Accessing crtc->state from interrupt handling code is unsafe, and it's updated before we shut down the pipe. For nonblocking modesets it's even worse. For atomic drivers try to implement what i915 does. To do that we add a new hwmode field to the vblank structure, and update it from drm_calc_timestamping_constants(). For atomic drivers that's called from the right spot by the helper library already, so all fine. But for safety let's enforce that. For legacy driver this function is only called at the end (oh the fun), which is broken, so again let's not bother and just stay bug-for-bug compatible. The benefit is that we can use drm_calc_vbltimestamp_from_scanoutpos directly to implement ->get_vblank_timestamp in every driver, deleting a lot of code. v2: Completely new approach, trying to mimick the i915 solution. v3: Fixup kerneldoc. v4: Drop the WARN_ON to check that the vblank is off, atomic helpers currently unconditionally call this. Recomputing the same stuff should be harmless. v5: Fix typos and move misplaced hunks to the right patches (Neil). v6: Undo hunk movement (kbuild).

drm/vblank: drop the mode argument from drm_calc_vbltimestamp_from_scanoutpos If we restrict this helper to only kms drivers (which is the case) we can look up the correct mode easily ourselves. But it's a bit tricky: - All legacy drivers look at crtc->hwmode. But that is updated already at the beginning of the modeset helper, which means when we disable a pipe. Hence the final timestamps might be a bit off. But since this is an existing bug I'm not going to change it, but just try to be bug-for-bug compatible with the current code. This only applies to radeon&amdgpu. - i915 tries to get it perfect by updating crtc->hwmode when the pipe is off (i.e. vblank->enabled = false). - All other atomic drivers look at crtc->state->adjusted_mode. Those that look at state->requested_mode simply don't adjust their mode, so it's the same. That has two problems: Accessing crtc->state from interrupt handling code is unsafe, and it's updated before we shut down the pipe. For nonblocking modesets it's even worse.
