Re: 答复: Regression with kernel 4.18 - AMD RX 550 fails IB ring test on power-up

2019-09-01 Thread Luís Mendes 
Good News!! I've re-tested this with Linux Kernel 5.3.0-rc6 with Ubuntu
19.4 and Mesa 19.0.2 and Mesa 19.0.8 with the same Polaris RX460 and the
same TYAN S7002 and TYAN S7025 and now it is working properly, being able
to enter the desktop and running glmark2 as well as OpenCL.

 IB test fail:

 This should be regression issue on 4.18, you can bisect the kernel

Re: 答复: Regression with kernel 4.18 - AMD RX 550 fails IB ring test on power-up

2018-10-20 Thread Luís Mendes 
The problems remains with Linux 4.18 and Linux 4.19 kernels. I am unable to
use AMD RX 460 and AMD RX 550 on my x64 Linux platforms.

I've installed Windows 10 in the same machine along with
win10-64bit-radeon-software-adrenalin-edition-18.10.1-oct18.exe and under
Windows the same RX 460 card *works fine* and I am able to run OpenCL
applications.

The driver is hanging since kernel 4.15, I am getting:
[   33.504100] [drm:drm_atomic_helper_wait_for_flip_done [drm_kms_helper]]
*ERROR* [CRTC:42:crtc-0] flip_done timed out

I get with kernels 4.18 and 4.19 as well as Ubuntu 18.10 stock kernel

2018-07-12 Thread Christian König 

Hi Luis,

well was "drm/amdgpu: defer test IBs on the rings at boot (V3)" does is 
delaying the IB test a bit and running it async to the rest of the bootup.


So what most likely happens is that some hardware feature (like power or 
clock gating) which doesn't works correctly on your system kicks in and 
lets the IB test fail.


It's rather likely that this problem is also responsible for the crashes 
you expect later on. So I think we should concentrate on fixing that.

You can set up remote connection by ssh, and also you can add amdgpu to 
blacklist first, and manually modprobe amdgpu.

What's about xinit? What is MESA driver version on your platform?
