[Bug 35457] [rs690m] Graphics corruption with ati x1200
by bugzilla-daemon＠freedesktop.org 14 Oct '15

https://bugs.freedesktop.org/show_bug.cgi?id=35457 --- Comment #102 from d4ddi0 <stillcompiling(a)gmail.com> --- (In reply to Micha from comment #101) > Another year with only a half working laptop :( > > Is there NOTHING I can do?!???!!!??! > > What causes the problems? The free radeon-driver? Mesa? > > PLEASE > HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! > !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! > !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! > !!!!!!!!!!!!!!! I looked at your screenshots, Micha. Your problem looks like it has to do with the font and typeface. Both applications look like they use graphical tilesets to display fonts. I have no idea whether you are experiencing the same type of corruption described in this bug or something else. The problem with my system (which was fixed) was that the manufacturer (Gateway) put incorrect information about the amount of video ram. The manufacturer never supported Linux, and this type of graphics chip is relatively rare and odd compared to other radeon families. Open source radeon developers try to support us, but they don't have our same hardware. To be honest, I don't expect any remaining bugs with rs690 to get much attention. They are hard to find, and often problems with the firmware or hardware that radeon devs can't fix, only try to work around. Bottom line: No one is still looking at the driver for this hardware. You have access to the source code and can try looking at it yourself, but the pros haven't been able to figure it out; it might be hard or impossible to fix. -- You are receiving this mail because: You are the assignee for the bug.

[PATCH 00/20] tree-wide convert to memremap()
by Dan Williams 14 Oct '15

14 Oct '15

The memremap() api [1] was merged in 4.3 [2] with an initial implementation for x86 and a conversion of the pmem driver. Complete the conversion for the rest of the kernel. Feel free to either ack or directly apply a conversion-patch as I will defer the final removal patches until all the conversions have landed.

8086:0f31_freezes_totally
by Chris Rainey 14 Oct '15

14 Oct '15

[1.] One line summary of the problem: 8086:0f31_freezes_totally [2.] Full description of the problem/report: Total lockup(cannot even switch to console via Alt-F1, F2, etc.). Bug is most easily reproducible via Chromium browser when opening multiple background-tabs(middle-button(wheel) mouse-clicks) and when using ALT-TAB to switch between browser and Xterms, etc. Very difficult to pin due to randomness(i.e. system may run for 30-seconds, 30-minutes or 30-hours before freeze). However -- it rarely runs stable for more that 24-48/hrs without a lockup.
