2020-01-16mm, drm/ttm: Fix vm page protection handlingThomas Hellstrom
TTM graphics buffer objects may, transparently to user-space, move between IO and system memory. When that happens, all PTEs pointing to the old location are zapped before the move and then faulted in again if needed. When that happens, the page protection caching mode- and encryption bits may change and be different from those of struct vm_area_struct::vm_page_prot. We were using an ugly hack to set the page protection correctly. Fix that and instead export and use vmf_insert_mixed_prot() or use vmf_insert_pfn_prot(). Also get the default page protection from struct vm_area_struct::vm_page_prot rather than using vm_get_page_prot(). This way we catch modifications done by the vm system for drivers that want write-notification.

2020-01-15drm/nouveau/acr: implement new subdev to replace "secure boot"Ben Skeggs
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 <bskeggs@redhat.com>
2020-01-15drm/nouveau/fb/gp102-: unlock VPR as part of FB initBen Skeggs
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 <bskeggs@redhat.com>

2020-01-15drm/nouveau/flcn/qmgr: support syncronous command submission from common codeBen Skeggs

2020-01-15drm/nouveau/flcn/qmgr: allow arbtrary priv + return code for callbacksBen Skeggs
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.
