2022-11-09drm/nouveau/acr: use common falcon HS FW code for ACR FWsBen Skeggs11-531/+240
Adds context binding and support for FWs with a bootloader to the code that was added to load VPR scrubber HS binaries, and ports ACR over to using all of it. - gv100 split from gp108 to handle FW exit status differences Signed-off-by: Ben Skeggs <[email protected]> Reviewed-by: Lyude Paul <[email protected]>

2022-01-25drm/nouveau/acr: Fix undefined behavior in nvkm_acr_hsfw_load_bl()Zhou Qingyang1-4/+5
In nvkm_acr_hsfw_load_bl(), the return value of kmalloc() is directly passed to memcpy(), which could lead to undefined behavior on failure of kmalloc(). Fix this bug by using kmemdup() instead of kmalloc()+memcpy(). This bug was found by a static analyzer. Builds with 'make allyesconfig' show no new warnings, and our static analyzer no longer warns about this code.

This will prevent some pain with broken firmware trees, as under some circumstances the HSFW can fail and leave the GPU in a state we don't know how to recover from. Signed-off-by: Ben Skeggs <[email protected]>

2020-01-15drm/nouveau/acr: implement new subdev to replace "secure boot"Ben Skeggs9-16/+1352
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 <[email protected]>
