- Rewrite of the ACR (formerly "secure boot") code, both to support Turing, support multiple FW revisions, and to make life easier when having to debug HW/FW bring-up in the future - Support for TU10x graphics engine, TU11x not available yet as FW isn't ready - Proper page 'kind' mappings for Turing - 10-bit LUT support - GP10B (Tegra) fixes - Misc other fixes Signed-off-by:

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: -

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: -

When the PMU/SEC2 LS FWs have booted, they'll send a message to the host with various information, including the configuration of message/command queues that are available. Move the handling for this to the relevant subdevs. Signed-off-by: -

This moves the code to generate commands for the ACR unit of the PMU/SEC2 LS firmwares to those subdevs. Signed-off-by: -

Takes the command queue pointer directly instead of requiring a function to lookup based on an queue type, as well as an explicit timeout value. Signed-off-by: -

This is to allow for proper separation of the LS interface code from the queue handling code. Signed-off-by: -

Functions implementing FW commands had to implement this themselves, let's move that to common code and plumb the return code from callbacks through. Signed-off-by: -

Code to interface with LS firmwares is being moved to the subdevs where it belongs, rather than living in the common falcon code. Arbitrary private data passed to callbacks is to allow for something other than struct nvkm_msgqueue to be passed into the callback (like the pointer to the subdev itself, for example), and the return code will be used where we'd like to detect failure from synchronous messages.

To make things clearer while modifying the interfaces, split msgqueue into Queue Manager, Command Queue, and Message Queue. There should be no code changes here, these will be done incrementally. Signed-off-by: -
