This patch set adds basic support for pre-booting GSP-RM on Turing. There is also partial support for GA100, but it's currently not fully implemented. GA100 is considered experimental in Nouveau, and so it hasn't been tested with NovaCore either.
That latest linux-firmware.git is required because it contains the Generic Bootloader image that has not yet been propogated to distros. Summary of changes: 1. Introduce non-secure IMEM support. For GA102 and later, only secure IMEM is used. 2. Because of non-secure IMEM, Turing booter firmware images need some of the headers parsed differently for stuff like the load target address. 3. Add support the tu10x firmware signature section in the ELF image. 4. Add several new registers used only on Turing. 5. Some functions that were considered generic Falcon operations are actually different on Turing vs GA102+, so they are moved to the HAL. 6. The FRTS FWSEC firmware in VBIOS uses a different version of the descriptor header. 7. I don't know why this isn't necessary on GA102+, but GSP-RM LIBOS args struct needs to have its 'size' field aligned to 4KB. 8. Turing Falcons do not support DMA, so PIO is used to copy images into IMEM/DMEM. Changes from v1: 1. Replaced pointer/length with slice in PIO code. 2. Added RFC patch to implement trait object FalconUCodeDescriptor . 3. Added comments to new registers, structs, and other places. 4. Fixed all CLIPPY complaints. 5. Added supports_dma() method for Falcon HAL 6. Renamed ImemSec and ImemNs to ImemSecure and ImemNonSecure 7. Several other miscellaneous fixes based on review comments.
