2026-01-05drm/amdgpu: add UMA allocation interfaces to sysfsYo-Jung Leo Lin (AMD)
Add a uma/ directory containing two sysfs files as interfaces to inspect or change UMA carveout size. These files are: - uma/carveout_options: a read-only file listing all the available UMA allocation options and their index. - uma/carveout: a file that is both readable and writable. On read, it shows the index of the current setting. Writing a valid index into this file allows users to change the UMA carveout size to that option on the next boot.

2026-01-05drm/amdgpu: Use explicit VCN instance 0 in SR-IOV initSrinivasan Shanmugam
vcn_v2_0_start_sriov() declares a local variable "i" initialized to zero and uses it only as the instance index in SOC15_REG_OFFSET(UVD, i, ...). The value is never changed and all other fields are taken from adev->vcn.inst[0], so this path only ever programs VCN instance 0. This triggered a Smatch: warn: iterator 'i' not incremented Replace the dummy iterator with an explicit instance index of 0 in SOC15_REG_OFFSET() calls.
