drm/amdgpu: Handle null atom context in VBIOS info ioctl

2023-10-06T12:56:54+00:00

[ Upstream commit 5e7e82254270c8cf8b107451c5de01cee2f135ae ] On some APU systems, there is no atom context and so the atom_context struct is null. Add a check to the VBIOS_INFO branch of amdgpu_info_ioctl to handle this case, returning all zeroes.

[ Upstream commit a0cc8e1512ad72c9f97cdcb76d42715730adaf62 ] Fixes the following: WARNING: min() should probably be min_t(size_t, size, sizeof(ip)) + ret = copy_to_user(out, &ip, min((size_t)size, sizeof(ip))); And other style fixes: WARNING: Prefer 'unsigned int' to bare use of 'unsigned' WARNING: Missing a blank line after declarations Cc: Christian König Cc: Alex Deucher Signed-off-by: Srinivasan Shanmugam Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher Signed-off-by: Sasha Levin

drm/amd: Add IMU fw version to fw version queries

2022-10-24T18:44:03+00:00

IMU is a new firmware for GFX11. There are four means by which firmware version can be queried from the driver: device attributes, vf2pf, debugfs, and the AMDGPU_INFO_FW_VERSION option in the amdgpu info ioctl. Add IMU as an option for those four methods. V2: Added debugfs Reviewed-by: Likun Gao Reviewed-by: Alex Deucher Signed-off-by: David Francis Signed-off-by: Alex Deucher

drm/amdgpu: use idr_init_base() to initialize fpriv->bo_list_handles

2022-07-28T14:35:55+00:00

idr_init_base(), implemented by commit 6ce711f27500 ("idr: Make 1-based IDRs more efficient"), let us set an arbitrary base other than idr_init(), which uses base 0. Since, for this IDR, no ID < 1 is ever requested/allocated, using idr_init_base(&idr, 1) avoids unnecessary tree walks.

drm/amdgpu: add the IP discovery IP versions for HW INFO data

Use the former pad element to store the IP versions from the IP discovery table. This allows userspace to get the IP version from the kernel to better align with hardware IP versions.
