I have an HD 5570 / Redwood PRO running three displays with Arch Linux. Upgrading xorg-server from 1.19.6-2 to 1.20.0-7 and xf86-video-ati from 1:7.10.0-1 to 1:18.0.1-2 causes display corruption with scan-out in the wrong sequence, cursor disappearing, failure to configure all three displays, and gigabytes of repetitive warnings in the system log, in the nature of: kernel: radeon 0000:05:00.0: evergreen_cs_track_validate_cb:481 cb[0] bo too small (layer size 15728640, offset 0, max layer 1, bo size 5242880, slice 61439) kernel: radeon 0000:05:00.0: evergreen_cs_track_validate_cb:485 problematic surf: (3840 1024) (4 4 1 1 2 1024 2) kernel: radeon 0000:05:00.0: evergreen_packet3_check:1948 invalid cmd stream 666 kernel: [drm:radeon_cs_ioctl [radeon]] *ERROR* Invalid command stream ! and kernel: [drm:radeon_cs_parser_relocs [radeon]] *ERROR* gem object lookup failed 0xa kernel: [drm:radeon_cs_ioctl [radeon]] *ERROR* Failed to parse relocation -2! kernel: radeon 0000:05:00.0: No GEM object associated to handle 0x0000000A, can't create framebuffer Sometimes the display can be made clear by switching to a virtual terminal and back to X, but generally, the display corruption will vary each time the X server is restarted, suggesting that the hardware configuration is not being set consistently or properly. Downgrading mesa does not resolve the problem, and the problem tracks with the X server version. The Xorg log showed: [ 82831.532] (WW) RADEON(0): get vblank counter failed: Invalid argument [ 82831.532] (WW) RADEON(0): flip queue failed: Invalid argument [ 82831.532] (WW) RADEON(0): Page flip failed: Invalid argument [ 82831.532] (EE) RADEON(0): present flip failed but then, blindly trying ~/.drirc <driconf> <device screen="0" driver="dri2"> <application name="Default"> <option name="vblank_mode" value="0" /> </application> </device> </driconf> seem to resolve these errors - which makes no sense to me, since the driver is suppose to default to dri3. For reference, the openbox window manager, commonly used with lxqt, cannot be made to display correctly, but kwin will work sometimes, and the wayland compositors do not seem to be affected. I also have another machine with an HD 4350 / RV710 running a single display which does _not_ show any of these problems at all.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
