kernel/linux.git/drivers/gpu/drm/amd/amdgpu/amdgpu_xgmi.c, branch linux-7.0.yLinux kernel stable tree (mirror)https://git.radix-linux.su/kernel/linux.git/atom?h=linux-7.0.y2026-02-22T01:09:51+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: Refactor sriov xgmi topology filling to common code2025-11-14T16:27:29+00:00Will Aitkenwiaitken@amd.com2025-09-30T16:24:07+00:00urn:sha1:f1a2cd427d0401c1888c04613fb18d272825a5c2
amdgpu_xgmi_fill_topology_info and psp_xgmi_reflect_topology_info
perform the same logic of copying topology info of one node to every
other node in the hive. Instead of having two functions that purport to
do the same thing, this refactoring moves the logic of the fill function
to the reflect function and adds reflecting port number info as well for
complete functionality.
