11.x/x86_64 Xorg ATI/radeon is broken

[y_satou70]

Since the recent Xorg-7.7-3d.tcz and other mesa related packages upgrade to version from 19.2.3 to 20.3.0, Xorg with ATI/Radeon driver is now crashed and failed to launch X:

This crash was recorded with new fresh install from repo.tinycorelinux.net (not upgrade), also I have a copy of previous tcz file sets of 11.x/x86_64 (e.g. mesa 19.2.3), and confirmed it can launch X properly without crash, so this was regression at this upgrade.

May be related to the following update news!

I doubt this issue is related with above topic, as that is just article related with for kernel 5.10 - TCL 11.x is kernel 5.4.3.

The current kernel and current driver timing seem to be close together

Does Xorg.0.log give any clues as to the problem?

above output is actually from Xorg.0.log.

[y_satou70]

attached full output of /var/log/Xorg.0.log, as well as /var/log/messages, and tce-status -i output for listing up installed tcz packages for your reference.
the device is Dell/Wyse Z00Q Cloud PC (and re-branded as 7020 Thin Client), using AMD Radeon HD 8400E graphics card.

I also had tested with HP ThinClient t620 which uses AMD Radeon HD 8330E graphics card, it also failed with ATI/Radeon driver.

[y_satou70]

and here is the log files of successful example - same hardware, with using previous version of TCZ packages(*) of 11.x x86_64.
(*) libdrm.tcz libGL.tcz libGLESv2.tcz libEGL.tcz Xorg-7.7-3d.tcz

I'd suggest you report it to the mesa developers.

[y_satou70]

I'd suggest you report it to the mesa developers.

this is not an problem of mesa source itself.
this is due to xf86-video-amdgpu.tcz has mismatch with updated mesa driver: as mesa (Xorg-7.7-3d.tcz) is upgraded, this package (and other xf86-video-*) needs to be re-compiled with updated Xorg-7.7-3d-dev.tcz

ref: http://repo.tinycorelinux.net/11.x/x86_64/tcz/src/xf86-video-amdgpu/compile_xf86-video-amdgpu

I rebuilt xf86-video-amdgpu.tcz with following above steps and confirmed it properly works without crash.
Please rebuild xf86-video-*.tcz packages with updated mesa.

[Juanito]

I rebuilt xf86-video-amdgpu.tcz with following above steps and confirmed it properly works without crash.

Please go ahead and submit the recompiled driver - I do not have the hardware to test and the xf86-video-intel driver works fine without needing to be recompiled.

[y_satou70]

looks updating mesa to 20.3.1 is the right path... I will test with rebuild Xorg-7.7-3d

from https://docs.mesa3d.org/relnotes/20.3.1.html

Mesa 20.3.1 Release Notes / 2020-12-16
Bug fixes:

• Mesa 20.3.0 and older ATi/Radeon cards fails

[/i]

[vinceASPECT]

Hello forum,
 
That   is some drivers issue.

thx

v....
.....

[y_satou70]

confirmed mesa 20.3.1 fixed the crash issue no ATI/Radeon video card with building from source code on 11.1 x86_64, will submit update contribution of TCZ files.

[Juanito]

There's no need, thanks - I'll update Xorg-7.7-3d in a few days time.
