kernel/linux.git/drivers/gpu/drm/amd/amdgpu/amdgpu_psp.c, branch v7.0.11Linux kernel stable tree (mirror)https://git.radix-linux.su/kernel/linux.git/atom?h=v7.0.112026-02-22T01:09:51+00:00Convert 'alloc_obj' family to use the new default GFP_KERNEL argument2026-02-22T01:09:51+00:00Linus Torvaldstorvalds@linux-foundation.org2026-02-22T00:37:42+00:00urn:sha1:bf4afc53b77aeaa48b5409da5c8da6bb4eff7f43
This was done entirely with mindless brute force, using
git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' |
xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/'
to convert the new alloc_obj() users that had a simple GFP_KERNEL
argument to just drop that argument.
Note that due to the extreme simplicity of the scripting, any slightly
more complex cases spread over multiple lines would not be triggered:
they definitely exist, but this covers the vast bulk of the cases, and
the resulting diff is also then easier to check automatically.
For the same reason the 'flex' versions will be done as a separate
conversion.

treewide: Replace kmalloc with kmalloc_obj for non-scalar types2026-02-21T09:02:28+00:00Kees Cookkees@kernel.org2026-02-21T07:49:23+00:00urn:sha1:69050f8d6d075dc01af7a5f2f550a8067510366f
This is the result of running the Coccinelle script from
scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to
avoid scalar types (which need careful case-by-case checking), and
instead replace kmalloc-family calls that allocate struct or union
object instances:
Single allocations: kmalloc(sizeof(TYPE), ...)
are replaced with: kmalloc_obj(TYPE, ...)
Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...)
are replaced with: kmalloc_objs(TYPE, COUNT, ...)
Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...)
are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...)
(where TYPE may also be *VAR)
The resulting allocations no longer return "void *", instead returning
"TYPE *".

drm/amdgpu: Adjust usleep_range in fence wait2026-02-12T20:21:41+00:00Ce Suncesun102@amd.com2026-02-10T07:32:01+00:00urn:sha1:3ee1c72606bd2842f0f377fd4b118362af0323ae
Tune the sleep interval in the PSP fence wait loop from 10-100us to
60-100us.This adjustment results in an overall wait window of 1.2s
(60us * 20000 iterations) to 2 seconds (100us * 20000 iterations),
which guarantees that we can retrieve the correct fence value

drm/amdgpu: Extend psp_skip_tmr for bare-metal and sriov2026-01-08T16:43:09+00:00Hawking ZhangHawking.Zhang@amd.com2026-01-04T14:37:56+00:00urn:sha1:5e3f50fda28f8c2912110a4a597021eb05762356
In SRIOV, guest drivers no longer setup/destory
VMR starting from mp0 v11_0_7.
In bare-metal, if boot-time TMR is enabled, some
generation (e.g., mp0 v13_0_x) don’t need runtime
TMR allocation but still require SETUP_TMR command
with tmr address 0 for backward compatibility.
some newer generations require neither SETUP_TMR nor
DESTROY_TMR and will return errors if they are sent.
Driver relies on boot_time_tmr and autoload_supported
to handle these cases correctly.
