2020-01-15drm/vmwgfx: check master authentication in surface_ref ioctlsEmil Velikov
With later commit we'll rework DRM authentication handling. Namely DRM_AUTH will not be a requirement for DRM_RENDER_ALLOW ioctls. Since vmwgfx does isolation for primary clients in different master realms, the DRM_AUTH can be dropped. The only place where authentication matters, is surface_reference ioctls whenever a legacy (non-prime) handle is used. For those ioctls we call vmw_surface_handle_reference(), where we explicitly check if the client is both a) master and b) unauthenticated - bailing out as result. Otherwise the usual isolation path kicks in and we're all good. v2: Reword commit message, since the isolation work has landed.

2020-01-15drm/vmwgfx: move the require_exist handling togetherEmil Velikov
Move the render_client hunk for require_exist alongside the rest. Keeping all the reasons why an existing object is needed, in a single place makes it easier to follow.

2020-01-15drm/vmwgfx: Replace deprecated PTR_RETLukas Bulwahn
Commit 508108ea2747 ("drm/vmwgfx: Don't refcount command-buffer managed resource lookups during command buffer validation") slips in use of deprecated PTR_RET. Use PTR_ERR_OR_ZERO instead. As the PTR_ERR_OR_ZERO is a bit longer than PTR_RET, we introduce local variable ret for proper indentation and line-length limits.

2020-01-15drm/vmwgfx: Don't use the HB port if memory encryption is activeThomas Hellstrom
With memory encryption active, the hypervisor typically can't read the guest memory using the HB port, since it is encrypted using a key known only to the guest. In that case fall back to processing 4 bytes at a time using the ordinary backdoor port. The other option would be to use unencrypted bounce buffers for the hypervisor to read out from or write into, but given the limited message sizes it appears more efficient to just fall back to the ordinary backdoor port.

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>

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.
