Bug ID: 109117 Summary: [ARM64] Unable to load module amdgpu on LS1012A-RDB board Product: DRI Version: XOrg git Hardware: ARM OS: All Status: NEW Severity: normal Priority: medium Component: DRM/AMDgpu Assignee: dri-devel@lists.freedesktop.org Reporter: bas@daedalean.ai

I am trying to use AMDGPU on an NXP LS1012A-RDB development board, connected to the mini PCIe connector on the board (x1 gen2).

I get the following problem, and the driver is unable to initialize it's rings correctly.
