From: Dave Airlie <airlied at redhat.com> Timur pointed this out before, and it just slipped my mind, but this might help some things work better, around pcie power management. Fixes: 8d55b0a940bb ("nouveau/gsp: add some basic registry entries.") Signed-off-by: Dave Airlie <airlied at redhat.com> --- drivers/gpu/drm/nouveau/nvkm/subdev/gsp/r535.c | 2 +- 1 file changed, 1

Using the end of rpc->entries[] for addressing runs into both compile-time and run-time detection of accessing beyond the end of the array. Use the base pointer instead, since was allocated with the additional bytes for storing the strings. Avoids the following warning in future GCC releases with support for __counted_by: In function 'fortify_memcpy_chk', inlined from

Fake flexible arrays (zero-length and one-element arrays) are deprecated, and should be replaced by flexible-array members. So, replace zero-length array with a flexible-array member in `struct PACKED_REGISTRY_TABLE`. Also annotate array `entries` with `__counted_by()` to prepare for the coming implementation by GCC and Clang of the `__counted_by` attribute. Flexible array members annotated with

Add the NVreg_RegistryDwords command line parameter, which allows specifying additional registry keys to be sent to GSP-RM. This allows additional configuration, debugging, and experimentation with GSP-RM, which uses these keys to alter its behavior. Note that these keys are passed as-is to GSP-RM, and Nouveau does not parse them. This is in contrast to the Nvidia driver, which may parse some
