[Ubuntu-x-swat] [Bug 1820323] Re: amdgpu-pro xorg crash

2020-01-16 Thread Chih-Hsyuan Ho
- Original shipping condition:
* Dell Farallon + WX2100
* linux-image-4.4.0-36-generic + amdgpu-17.10-429170

- Test procedure:
1. sudo apt install linux-image-4.4.0-xxx-generic 
linux-headers-4.4.0-xxx-generic
2. reboot 

Expected behavior 
System can boot into desktop successfully to the updated kernel

Actual behavior 
Loop at login session

- Findings:
1. amdgpu DKMS fails to build exactly between 4.4.0-142(OK) and 4.4.0-143(NG) 
kernels
2. However, starting from 4.4.0-116 kernel, amdgpu module fails to load with 
the following error message:
amdkcl: version magic '4.4.0-xxx-generic SMP mod_unload modversions' should be 
'4.4.0-xxx-generic SMP mod_unload modversions retpoline' 

- In summary, the issue has 2 causes, amdgpu loading error and amdgpu
DKMS build error, the former happens in earlier kernel revisions than
the latter.

We were using Ubuntu 16.04 for the test and the issue was indeed gone
after applying what's in xenial-proposed. The info I gave on comment #5
is not correct. What we originally had is 2.4.67-1 (failed), and after
applying xenial-proposed, it is 2.4.67-1ubuntu0.16.04.1(good) Sorry
about the confusion.

Regarding the (EE) error messages shown in Xorg.0.log, can you give the

And in other AMD A+A platforms such as [AMD Richland + Mars], which this
issue was originally reported against, switchable graphics works with
the latter Catalyst driver (14.502, earlier drivers may also work but
not verified) after disabling gpumanager so that the X configuration is
not further overwritten by it.

According to AMD engineering, the A+A platforms based on Mullings and
Beema chipsets do NOT support switchable graphics. It is made clear that
in their GUI configuration tool (AMDCCCLE), no such option exists for
such platforms.

[Ubuntu-x-swat] [Bug 1332489] Re: [Dell Inspiron 5547] AMD Radeon R7 M260 [1002:6900] Unable to resume from suspend with fglrx

2014-07-24 Thread Chih-Hsyuan Ho
@Po-Hsu, we would need more info on the system config when the issue is
happening. With AMD's fglrx driver installed, can you help make sure
what graphics mode (I or A) when the issue happens?

To find out which graphics module is in use:

aticonfig --pxl

To switch to Intel, run the following command and reboot:

sudo aticonfig --px-igpu

To switch to AMD, run the following command and reboot:

sudo aticonfig --px-dgpu

Please also include the /var/log/syslog file after failure happens.
Thanks.

2014-07-10 Thread Chih-Hsyuan Ho
@Yung, if the Switchable Graphics is enabled in BIOS, the PX mode that
AMD referred to should already be there. And according to AMD team,
switchable graphics in AMD Richland should just work.

Can you help provide more info by going through the following commands:

aticonfig --lsa

Is the xorg.conf existent? If not, can you run the following command to
create one?

sudo amdconfig --initial --force --adapter=all

Afterwards, please reboot the system and retest this issue. Thank you.
