drm/radeon: Add HAINAN clock adjustment

2026-03-04T12:20:57+00:00

[ Upstream commit 908d318f23d6b5d625bea093c5fc056238cdb7ff ] This patch limits the clock speeds of the AMD Radeon R5 M420 GPU from 850/1000MHz (core/memory) to 800/950 MHz, making it work stably. This patch is for radeon. Signed-off-by: decce6 Signed-off-by: Alex Deucher Signed-off-by: Sasha Levin

drm/radeon: delete radeon_fence_process in is_signaled, no deadlock

2026-02-06T15:48:28+00:00

[ Upstream commit 9eb00b5f5697bd56baa3222c7a1426fa15bacfb5 ] Delete the attempt to progress the queue when checking if fence is signaled. This avoids deadlock. dma-fence_ops::signaled can be called with the fence lock in unknown state. For radeon, the fence lock is also the wait queue lock. This can cause a self deadlock when signaled() tries to make forward progress on the wait queue. But advancing the queue is unneeded because incorrectly returning false from signaled() is perfectly acceptable.

minmax: make generic MIN() and MAX() macros available everywhere

2025-10-02T11:42:55+00:00

[ Upstream commit 1a251f52cfdc417c84411a056bc142cbd77baef4 ] This just standardizes the use of MIN() and MAX() macros, with the very traditional semantics. The goal is to use these for C constant expressions and for top-level / static initializers, and so be able to simplify the min()/max() macros. These macro names were used by various kernel code - they are very traditional, after all - and all such users have been fixed up, with a few different approaches: - trivial duplicated macro definitions have been removed Note that 'trivial' here means that it's obviously kernel code that already included all the major kernel headers, and thus gets the new generic MIN/MAX macros automatically. - non-trivial duplicated macro definitions are guarded with #ifndef This is the "yes, they define their own versions, but no, the include situation is not entirely obvious, and maybe they don't get the generic version automatically" case. - strange use case #1 A couple of drivers decided that the way they want to describe their versioning is with #define MAJ 1 #define MIN 2 #define DRV_VERSION __stringify(MAJ) "." __stringify(MIN) which adds zero value and I just did my Alexander the Great impersonation, and rewrote that pointless Gordian knot as #define DRV_VERSION "1.2" instead. - strange use case #2 A couple of drivers thought that it's a good idea to have a random 'MIN' or 'MAX' define for a value or index into a table, rather than the traditional macro that takes arguments. These values were re-written as C enum's instead. The new function-line macros only expand when followed by an open parenthesis, and thus don't clash with enum use. Happily, there weren't really all that many of these cases, and a lot of users already had the pattern of using '#ifndef' guarding (or in one case just using '#undef MIN') before defining their own private version that does the same thing. I left such cases alone. Cc: David Laight Cc: Lorenzo Stoakes Signed-off-by: Linus Torvalds Signed-off-by: Eliav Farber Signed-off-by: Greg Kroah-Hartman

drm/radeon: fix uninitialized size issue in radeon_vce_cs_parse()

2025-03-28T20:59:55+00:00

commit dd8689b52a24807c2d5ce0a17cb26dc87f75235c upstream. On the off chance that command stream passed from userspace via ioctl() call to radeon_vce_cs_parse() is weirdly crafted and first command to execute is to encode (case 0x03000001), the function in question will attempt to call radeon_vce_cs_reloc() with size argument that has not been properly initialized. Specifically, 'size' will point to 'tmp' variable before the latter had a chance to be assigned any value. Play it safe and init 'tmp' with 0, thus ensuring that radeon_vce_cs_reloc() will catch an early error in cases like these.
