drm/radeon: Add HAINAN clock adjustment

2026-03-04T12:20:48Z

[ 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: Remove __counted_by from ClockInfoArray.clockInfo[]

2026-01-05T22:23:41Z

clockInfo[] is a generic uchar pointer to variable sized structures which vary from ASIC to ASIC.

drm/fb-helper: Allocate and release fb_info in single place

2025-11-25T10:02:43Z

Move the calls to drm_fb_helper_alloc_info() from drivers into a single place in fbdev helpers. Allocates struct fb_info for a new framebuffer device. Then call drm_fb_helper_single_fb_probe() to create an fbdev screen buffer. Also release the instance on errors by calling drm_fb_helper_release_info(). Simplifies the code and fixes the error cleanup for some of the drivers. Regular release of the struct fb_info instance still happens in drm_fb_helper_fini() as before. v2: - remove error rollback in driver implementations (kernel test robot) - initialize info in TTM implementation (kernel test robot) Signed-off-by: Thomas Zimmermann Acked-by: Christian König # radeon Acked-by: Dmitry Baryshkov # msm Acked-by: Javier Martinez Canillas Link: https://patch.msgid.link/20251027081245.80262-1-tzimmermann@suse.de

drm/radeon: delete radeon_fence_process in is_signaled, no deadlock

2025-11-18T15:52:32Z

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.

drm/amdgpu: Use amdgpu by default on SI dedicated GPUs (v2)

2025-11-14T16:28:29Z

Now that the DC analog connector support and VCE1 support landed, amdgpu is at feature parity with the old radeon driver on SI dGPUs. Enabling the amdgpu driver by default for SI dGPUs has the following benefits: - More stable OpenGL support through RadeonSI - Vulkan support through RADV - Improved performance - Better display features through DC Users who want to keep using the old driver can do so using: amdgpu.si_support=0 radeon.si_support=1 v2: - Update documentation in Kconfig file Reviewed-by: Christian König Signed-off-by: Timur Kristóf Signed-off-by: Alex Deucher

drm/amdgpu: Use amdgpu by default on CIK dedicated GPUs

2025-11-14T16:27:24Z

The amdgpu driver has been working well on CIK dGPUs for years. Now that the DC analog connector support landed, these GPUs are at feature parity with the old radeon driver. Additionally, amdgpu yields extra performance, supports Vulkan and provides more display features through DC as well as more robust power management.

drm/radeon: Refactor how SI and CIK support is determined

2025-11-14T16:27:04Z

Move the determination into a separate function. Change radeon.si_support and radeon.cik_support so that their default value is -1 (default). This prepares the code for changing the default driver based on the chip. Signed-off-by: Timur Kristóf Signed-off-by: Alex Deucher
