Firmware for R500?
It is now claimed that "IRQ microcode is required for R500 and newer GPUs." This is misleading. The R520_cp.bin file which is mentioned for whatever historical reason in the firmware table has been part of a non-deblobbed kernel since it gained support for R500.

If there are no objections I will revert the misleading change and also remove the reference to R520_cp.bin.

glamor acceleration
Currently, glamor is listed as not recommended. But it is the only working 2D acceleration for Southern Islands. Should the recommendation be changed, or a note be added to the table of USE flags? --Chithanh (talk) 19:37, 9 May 2013 (UTC)


 * Remove the non recommendation and add to the USE flag description a note. Astaecker (talk) 08:03, 10 May 2013 (UTC)


 * Like that?

 * Nice solution. But don't miss the USE flag description:

 * ok, I added descriptions. --Chithanh (talk) 17:05, 16 May 2013 (UTC)

Firmware for UVD
Since gentoo-sources-3.9.1 the UVD patchset is included. This requires new firmware which has not reached stable yet. The firmware files are the following: Should they be in the normal firmware table? Or an extra table for the time being? --Chithanh (talk) 19:37, 9 May 2013 (UTC)


 * Add them to the normal firmware table and use references (below the table) to add additional information, see the Feature table. Astaecker (talk) 08:01, 10 May 2013 (UTC)
 * Ok, added. --Chithanh (talk) 17:16, 11 May 2013 (UTC)

agpgart/intel?
Is there any reason these two are checked (especially the second one)? Was this just a copy-paste from the intel article, or is there an actual reason why they should be enabled?

--Alec 22:55, 22 November 2011 (UTC)


 * Good catch! I had this checked in my kernel but it is something specific to my old laptop. --Lidel 23:17, 22 November 2011 (UTC)
 * Checked today -- my old notebook had i915 intel chip. Sorry about causing confusion. --Lidel 20:30, 24 November 2011 (UTC)


 * CONFIG_DRM_RADEON - Depends on: HAS_IOMEM [=y] && DRM [=y] && PCI [=y] so it isn't required?
 * But alas:
 * So its still a good idea if its sits on a AGP port? Any expert about? /Ni1s 23:22, 22 November 2011 (UTC)


 * I changed the intel line to AMD (since that's obviously wrong), but I'm now really curious if my PhenomII board with an on-board Radeon needs agpgart... --Alec 02:15, 23 November 2011 (UTC)

Not for Proprietary drivers?
This wiki appears to be for the open source drivers only, and not for the proprietary AMD/ATI drivers.

If this is correct, the please make a note of this, and redirect those who wish to use proprietary drivers to another source (e.g. Fglrx).
 * this article is indeed for the open source radeon driver, you could create a new article for the fglrx driver, because they are hardly related. Disi 22:28, 6 July 2012 (UTC)

Radeon HD 7340
I have an AMD E-series APU with Wrestler Radeon HD7340. In addition to the firmware files listet under Evergreen - PALM (Wrestler), I had to include radeon/SUMO_rlc.bin in my kernel to make in work.

Firmware for HD6320 (AMD E-450)
So I have SUMO, when I put: CONFIG_EXTRA_FIRMWARE="radeon/SUMO_me.bin radeon/SUMO_pfp.bin radeon/SUMO_rlc.bin radeon/SUMO_uvd.bin"

dmesg said: [   1.551956] r600_cp: Failed to load firmware "radeon/PALM_pfp.bin" [   1.552056] [drm:evergreen_startup] *ERROR* Failed to load firmware! [   1.552106] radeon 0000:00:01.0: disabling GPU acceleration Here is full output: http://pastebin.com/8pdxr5HJ

So maybe I need both from PALM as well: radeon/PALM_me.bin radeon/PALM_pfp.bin


 * I can confirm that, had the same problem with HD6320 and solved it by adding PALM firmware

HDMI
I am not sure if "radeon.audio" has any more effect on kernels newer than 3.13. Also this options seems to be accessible by xrandr now: phoronix.com

OpenGL support does not match Xorg features matrix
The Xorg features matrix for the Radeon driver lists support for higher versions of OpenGL than this page. Is that a mistake on this page or is there a reason that Gentoo does not support the same versions?

Full memory clock speed


Where is the source for this? I remember reading a kernel commit message regarding this change. I remember when 3.13 came out, I disabled dpm (by using the kernel argument) and this worked for a while. Recently I jumped to 3.16.2 and this "trick" doesn't work any more (radeon lags screen updates). I suspect this is caused by the clock speed issue.
