Notes

Closed source GPU driver

You can install and use the proprietary AMD Catalyst drivers, where the problems with the open source driver may not occur.
Versions that work well: (14.2 beta)
(Version 12.3 seems to work quite well, with very good performance as well)

Open source GPU driver

This section details the open source GPU driver's problems and workarounds.

TLDR

Use following kernel parameters for good stable use.

  • acpi_sleep=s3_bios (ensures that laptop screen will work again after suspend and resume)
  • radeon.runpm=0 (disables automatically switching off GPU due to GPU hangs) - for linux >= 3.13
  • radeon.dpm=1 (new power management code)
Power management

Recommend using Linux kernel >= 3.11 - proper power management resulting in better performance and lower temperatures. Requires AMD GPU firmware as well, should be included in distribution's Linux firmware package.
All firmware can be found here: http://people.freedesktop.org/~agd5f/radeon_ucode/

GPU hangs on suspend, resume, shutdown

For Linux kernel >= 3.13 , GPU hangs during suspend, resume and shutdown. As a temporary workaround, boot with kernel parameter radeon.runpm=0. This will turn off the runtime power management that automatically shuts off the dedicated GPU (if present) when unused. It does not affect dpm (the new power management code).

Blank laptop screen after suspend and resume

Laptop screen is blank (backlight off) after suspending and resuming when using the open source driver.
https://bugs.freedesktop.org/show_bug.cgi?id=42960
Workaround: Use kernel parameter acpi_sleep=s3_bios

Glamor 2D acceleration

Glamor uses OpenGL for 2D acceleration instead of DDX (xf86-video-ati). Might be faster, especially with enhancements to Glamor in X.Org 1.16
Glamor 2D acceleration may not work properly - in any case, it is optional and by default EXA is used.

HyperZ

Might increase OpenGL performance significantly.
Can enable HyperZ support by setting this environment variable: R600_DEBUG=hyperz
You can use the command 'export R600_DEBUG=hyperz' in the terminal, and then launch programs from the same terminal. The launched program will use HyperZ for OpenGL drawing.

Hybrid/Dual graphics

With the open source driver, the dedicated GPU is not currently used. You can try using it by running the following commands:

  • xrandr –setprovideroffloadsink 0x55 0x8a
  • export DRI_PRIME=1
  • <launch-your-program>

Can check with glxinfo after 2nd command - should say TURKS instead of SUMO

Apparently, compositing needs to be turned on for this to work (the special effects that desktop environments/window managers use) - otherwise the window is just blank. Can be buggy and only works well for some software.

There are some changes in newer X.Org/DRI/DRM versions to fix bugs with this feature, and enable it even if compositing is not used. These should be available in X.Org 1.16

Summary

Overall works well when using latest stable software.

for those inclined to overclock this system's cpu,

will be helpful to you.

k10ctl is a k10 family cpu overclocking program.
