drm/nouveau/gr/gp10b: Use gp100_grctx and gp100_gr_zbc

2020-01-22T22:56:51+00:00

gp10b doesn't have all the registers that gp102_gr_zbc wants to access, which causes IBUS MMIO faults to occur. Avoid this by using the gp100 variants of grctx and gr_zbc. Signed-off-by: Thierry Reding Signed-off-by: Ben Skeggs

drm/nouveau/acr: implement new subdev to replace "secure boot"

2020-01-15T00:50:29+00:00

ACR is responsible for managing the firmware for LS (Low Secure) falcons, this was previously handled in the driver by SECBOOT. This rewrite started from some test code that attempted to replicate the procedure RM uses in order to debug early Turing ACR firmwares that were provided by NVIDIA for development. Compared with SECBOOT, the code is structured into more individual steps, with the aim of making the process easier to follow/debug, whilst making it possible to support newer firmware versions that may have a different binary format or API interface. The HS (High Secure) binary(s) are now booted earlier in device init, to match the behaviour of RM, whereas SECBOOT would delay this until we try to boot the first LS falcon. There's also additional debugging features available, with the intention of making it easier to solve issues during FW/HW bring-up in the future. Signed-off-by: Ben Skeggs

drm/nouveau/gr/gf100-: initialise SW state for falcon from constructor

2020-01-15T00:50:27+00:00

This will allow us to register the falcon with ACR, and further customise its behaviour by providing the nvkm_falcon_func structure directly. Signed-off-by: Ben Skeggs

drm/nouveau/gr/gf100-: select implementation based on available FW

2020-01-15T00:50:27+00:00

This will allow for further customisation of the subdev depending on what firmware is available. Signed-off-by: Ben Skeggs

drm/nouveau/gr/gp108: split from gp107

2020-01-15T00:50:27+00:00

ACR LS FW loading is moving out of SECBOOT and into their specific subdevs, and the available GP107/GP108 FWs have interface differences. Signed-off-by: Ben Skeggs
