2018-05-18drm/nouveau/gr/gf100-: virtualise dist_skip_table + improve algorithmBen Skeggs14-16/+51
The algorithm for GM200 and newer matches RM for all the boards I have, but I don't have enough data to try and figure something out for earlier boards, so these will still write zeroes to the table as we did before. The code in NVGPU isn't helpful here, it appears to handle specific cases. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2018-05-18drm/nouveau/gr/gf100-gf119: modify max_ways_evict where requiredBen Skeggs7-0/+19
I don't think this is done after Fermi, NVGPU used to do it but removed the code, and I've not seen RM traces touching it either. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2018-05-18drm/nouveau/gr/gf100-: virtualise alpha_beta_tables + improve algorithmsBen Skeggs15-35/+201
I haven't yet been able to find a fully programatic way of calculating the same mapping as NVIDIA for GF100-GF119, so the algorithm partially depends on data tables for specific configurations. I couldn't find traces for every possibility, so the algorithm will switch to a mapping similar to what GK104-GM10x use if it encounters one. We did the wrong thing before anyway, so shouldn't matter too much. The algorithm used in the GK104 implementation was ported from NVGPU. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2018-05-18drm/nouveau/gr/gf100-: virtualise tpc_per_gpcBen Skeggs9-37/+10
GM20B now also shares the same code, as NVGPU shows it doesn't need special treatment. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2018-05-18drm/nouveau/fifo/gk104-: poll for runlist update completionBen Skeggs1-4/+4
Newer HW doesn't appear to send this event, which will cause long delays in runlist updates if they don't complete immediately. RM doesn't use these events anywhere, and an NVGPU commit message notes that polling is the preferred method even on HW that supports the event. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

allocation We didn't used to be aware that runlist/engine IDs weren't the same thing, or that there was such variability in configuration between GPUs. By exposing this information to a client, and giving it explicit control of which runlist it's allocating a channel on, we're able to make better choices. The immediate effect of this is that on GPUs where CE0 is the "GRCE", we will now be allocating a copy engine running asynchronously to GR for BO migrations - as intended.
