drm/nouveau/fb/gp102-: allow module to load even when scrubber binary is missing

2020-01-29T05:49:56+00:00

Without relaxing this requirement, TU10x boards will fail to load without an updated linux-firmware, and TU11x will completely fail to load because FW isn't available yet. Signed-off-by: Ben Skeggs

drm/nouveau/acr: return error when registering LSF if ACR not supported

2020-01-29T05:49:56+00:00

This fixes an oops on TU11x GPUs where SEC2 attempts to register its falcon, and triggers a NULL-pointer deref because ACR isn't yet supported. Signed-off-by: Ben Skeggs

drm/nouveau/pmu/gm20b,gp10b: Fix Falcon bootstrapping

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

The low-level Falcon bootstrapping callbacks are expected to return 0 on success or a negative error code on failure. However, the implementation on Tegra returns the ID or mask of the Falcons that were bootstrapped on success, thus breaking the calling code, which treats this as failure. Fix this by making sure we only return 0 or a negative error code, just like the code for discrete GPUs does.

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/fb/gp102-: unlock VPR as part of FB init

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

We perform memory allocations long before we hit the code in SECBOOT that would unlock the VPR, which could potentially result in memory allocation within the locked region. Run the scrubber binary right after VRAM init to ensure we don't. Signed-off-by: Ben Skeggs
