2024-07-23drm/radeon: change drm_dev_alloc to devm_drm_dev_allocWu Hoi Pok4-15/+12
"drm_dev_alloc" is deprecated, in order to use the newer "devm_drm_dev_alloc", the "drm_device" is stored inside "radeon_device", by changing "rdev_to_drm(rdev)" other functions still gain access to the member "drm_device". Also, "devm_drm_dev_alloc" is now allocating "radeon_device", allocation inside "radeon_driver_load_kms" has to be removed. In "radeon_device_init", it originally assigned "rdev->dev" etc. However it is already done right after "devm_drm_dev_alloc" as you can see down below. It is better remove them.

Add helper rdev_to_drm(rdev), similar to amdgpu, most function should access the "drm_device" with "rdev_to_drm(rdev)" instead, where amdgpu has "adev_to_drm(adev)". It also makes changing from "*drm_device" to "drm_device" in "radeon_devicce" later on easier.

2024-07-23drm/amd/display: Replace assert with error message in dp_retrieve_lttpr_cap()Roman Li1-1/+5
[Why] When assert in dp_retrieve_lttpr_cap() is hit, dmesg has traces like: RIP: 0010:dp_retrieve_lttpr_cap+0xcc/0x1a0 [amdgpu] Call Trace: <TASK> dp_retrieve_lttpr_cap+0xcc/0x1a0 [amdgpu] report_bug+0x1e8/0x240 handle_bug+0x46/0x80 link_detect+0x35/0x580 [amdgpu] It happens when LTTPRs fail to increment dpcd repeater count. We have a recovery action in place for such cases. Assert is misleading, an indicative error in dmesg is more useful. [How] Remove ASSERT and use DC_LOG_ERROR instead.

2024-07-23drm/amd/display: Don't consider cursor for no plane case in DML1Alvin Lee1-0/+2
[Description] For no plane scenarios we should not consider cursor as there cannot be any cursor if there's no planes. This fixes an issue where dc_commit_streams fails due to prefetch bandwidth requirements (the display config + dummy planes + cursor causes the prefetch bandwidth to exceed what is possible).
