Open-Source AMD Fusion E-350 Support Takes A Dive

[chithanh]

How about downloading and building a kernel.org kernel? I have no problem on my ASRock E350M1 using 2.6.38_rc6
The firmware files can be downloaded from here, too: http://people.freedesktop.org/~agd5f/radeon_ucode/

[chithanh]

btw. your new dmesg looks like bug 34137. Workaround: Option "EnablePageFlip" "false" in xorg.conf

Looks like these got lost in the merge time, should fix bug
posted on phoronix in an article. (Note this isn't how you report
bugs).

Dave, I can confirm that the patch atop Linus' tree as of this evening (10 March) fixes my E-350 setup. Acceleration appears to be working fine with KMS and Gallium3D. Thanks.

P.S. I am sorry that you may not like some of my unconventional bug reporting techniques etc, but we all share a common goal -- and that is to improve Linux hardware support. We may just have different approaches to doing so, but this method at least gets the job done (I see that bug #34137 was open for one month with no responses at all) and concurrently allows me to finance my time and hardware expenses.

Seems to me you could do both : write an article **AND** a bug report.

But it's hard to write such a sensationalist story if you do

Will this get pulled for final or get more testing? Thanks

Yeah, Dave. Made my day.

[airlied]

my main issue isn't with the article, but with the not filing a bug upstream so I can ask for more info and have logs that aren't a pastebin.

drm.debug=15 runs would have been useful.

It was only by luck I was tracking down another bug in page flip today and saw the problem in passing.

Dealing with bug reports tends to be tedious and chews up a lot of time... I did let Alex and John know though a day in advance via email soon as I discovered the issue.
