Created attachment 143482 [details] error_dmesg We enabled the Radeon OLAND series of graphics cards on ARM, very old graphics cards, The kernel is a 4.14 kernel and there is a problem with GPU acceleration not being enabled: The kernel initialization log is as follows, there are 2 errors, one is radeon 0000:43:00.0: failed VCE resume (-110). One is [drm:r600_ring_test [radeon]] *ERROR* radeon: ring 0 test failed (scratch(0x850C)=0xCAFEDEAD), this error causes the GPU acceleration function to be turned off. Can you ask me what it is, or how to position it next? thank you.

For this one, make sure you have this patch: https://cgit.freedesktop.org/drm/drm/commit/?id=e02f5c1bb2283cfcee68f2f0feddcc06150f13aa and also make sure your ARM platform supports cache coherence as required by the PCI spec.
And also please try an up to date kernel. We certainly won't fix any architecture specific problems in 4.14 any more.
