From 22dcda45a3d1dfe6eeb4ab0a3b9aaa2333cb649d Mon Sep 17 00:00:00 2001 From: Ben Skeggs Date: Wed, 15 Jan 2020 06:34:22 +1000 Subject: drm/nouveau/acr: implement new subdev to replace "secure boot" 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.
