Bug#943664: xserver-xorg-video-radeon 19.1 (ppc64) crash at startup: undefined symbol: exaGetPixmapDriverPrivate

So have been trying the suggested workarounds. The only driver that seems to “work” for unaccelerated graphics is fbdev. In that case Qt even manages to fall back to llvmpipe and render OpenGL (Qt Quick) content mostly correctly. But of course, having a GPU, I’d certainly rather be able to use it. The modesetting driver with AccelMethod “none” will start, but the color rendering has obvious issues probably related to endianness: black turns into bright blue, glxgears runs (via software emulation apparently) but the gears are cyan and magenta on a bright blue background, and generally hard to see. I work on Qt. Once in a while I build and test Qt on this machine to see what endian-related issues are showing up, and try to fix them as a low-priority thing. I needed to upgrade to sid because Debian 8 was the last version that actually had a PPC big-endian 64-bit release, and the compiler on that version is getting long in the tooth; Qt 5.14 doesn’t build so easily anymore with such an old one. GPU seems to be an AGP Radeon 9600; lspci says :f0:10.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] RV350 [Radeon 9550/9600/X1050 Series] BTW if I try to use amdgpu, I ran into the issue that glamor requires 128 or more instructions but this GPU only supports 64. So it would really need to be radeon_drv for best performance I suppose. (By comparison, on Debian 8 the radeon driver is automatically chosen, but the log says GPU access disabled or not working, using shadowfb for KMS. The colors are fine, but the OpenGL performance is not good, of course.)

Hi. I assume that the error occurs on the PPC64 system because of disabled HA (Hardware Acceleration) too: According to https://bugs.freedesktop.org/show_bug.cgi?id=99851 a "ring 0 test failed" message from drm means that HA gets disabled. dmesg | grep -i drm [5.621228] [drm] radeon kernel modesetting enabled.

In my opinion it would be great if: 1) xserver-xorg-video-radeon_1%3a19.1.0-1 would not fail but fall back to frame buffer device like xserver-xorg-video-radeon_1%3a19.0.1-1 2) the "ring 0 test" would not fail According to the last post from the link above the failure was seen in 4.14.4 and 4.15-rc2 but not in kernel 4.17.2. Maybe I should get/compile a linux 4.17.2 kernel. Thank you and best regards, Ralf

Package: xserver-xorg-video-radeon Version: 1:19.0.1-1 Severity: grave Justification: renders package unusable Dear Maintainer, on the ppc64 architecture the package xserver-xorg-video-radeon_1%3a19.1.0-1_ppc64.deb crashes the xserver at startup. Xorg complains about an undefined symbol: exaGetPixmapDriverPrivate The bug occured after an update from: xserver-xorg-video-radeon_1%3a19.0.1-1_ppc64.deb to:xserver-xorg-video-radeon_1%3a19.1.0-1_ppc64.deb To make sure the bug is in xserver-xorg-video-radeon 19.1.0-1 I switched several times between these two versions of the package. As soon as version 19.0.1-1 is installed, Xorg runs well.
