radeon Disabling GPU acceleration (WB disabled?)

I tried 5.2, 5.3 and 5.4-rc4 on my old Fujitsu RX220 with integrated Radeon RV100. Dmesg tells that GPU acceleration is disabled. I do not know if it has been enabled in the past - no old kernels handy at the moment. From dmesg it looks like something with MTRR maybe: WB disabled. Any ideas wh

radeon UBSAN warning from user syscall

I tried latest (5.4) custom kernel (with UBSAN) on my Dell D600 laptop and found that it exhibits a UBSAN warning triggered by userspace ioctl. Here is dmesg with anything radeon-related + the warning, and config: [ 17.659534] [drm] radeon kernel modesetting enabled. [ 17.659607] radeon 000

Re: radeon UBSAN warning from user syscall

Looks like the shift and mask are reversed. Does this patch fix it? Yes, the warning is gone and it still works. Thank you! Tested-by: Meelis Roos ___ amd-gfx mailing list amd-gfx@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo

https://bugzilla.kernel.org/show_bug.cgi?id=198123 No, I just put the card in and tested with only the current kernels I had. I can get some older kernel and test with that if that is of any help. -- Meelis Roos ___ amd-gfx mailing list am

Re: Radeon HD 7450 brightness oversaturated

I can get some older kernel and test with that if that is of any help. Just tested Debianis 4.19.0-4 package (4.19.28) and it exhibits the same symptoms. Slight additional detail: chenaging between fbcon vt-s does not fix it, only changing between fbcon and X fixes it. -- Meelis

y, I can not reproduce it, so it looks like random noise from an old computer. About 10 reboots later, I have not managed to reproduce this problem. -- Meelis Roos (mr...@linux.ee) ___ amd-gfx mailing list amd-gfx@lists.freedesktop.org https://lists.fre
