This reverts commit 7294863a6f01248d72b61d38478978d638641bee. This commit was erroneously applied again after commit 0ab5d711ec74 ("drm/amd: Refactor `amdgpu_aspm` to be evaluated per device") removed it, leading to very hard to debug crashes, when used with a system with two AMD GPUs of which only one supports ASPM.

drm/amd/display: Add an hdmi_hpd_debounce_delay_ms module

2026-01-14T20:07:43+00:00

[Why&How] Right now, the HDMI HPD filter is enabled by default at 1500ms. We want to disable it by default, as most modern displays with HDMI do not require it for DPMS mode. The HPD can instead be enabled as a driver parameter with a custom delay value in ms (up to 5000ms).

The behavior for amdgpu was changed with commit e00e5c223878 ("drm/amdgpu: adjust drm_firmware_drivers_only() handling") to potentially allow loading even if nomodeset was set, so the message is no longer accurate. Just drop it to avoid confusion.

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

2025-11-14T16:28:29+00:00

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
