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?
 * --Chithanh (talk) 16:54, 11 May 2013 (UTC)


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


 * Astaecker (talk) 07:37, 13 May 2013 (UTC)


 * 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.

Radeon Video Coding Engine firmware () might be needed in other chips
After going in circles for a while, I have found out that my Apple MacBookPro11,5 laptop has a graphic chip [AMD/ATI] Venus XT [Radeon HD 8870M / R9 M270X/M370X] (rev 83) ( lspci -s 01:00 ), that has PCI ID 1002:6821 (rev 83), subsystem 106b:0149 ( lspci -s 01:00 ), and that thing seems to be a AMD R9 M370X, Mac edition (http://www.notebookcheck.net/AMD-Radeon-R9-M370X.142763.0.html; http://www.amd.com/en-us/products/graphics/notebook/r9-m200) &mdash; here I am not sure &mdash; and that this is some type of Cape Verde chip. When I load kernel driver, it complains it also wants. From the code of the driver, it seems that this applies to all Cape Verde chips, and on all Pitcairn, Oland, Aruba and Tahiti chips too. I don't trust myself enough to add these to the text, nor I have means to test these other cards. --Hamlet (talk) 20:31, 25 July 2016 (UTC) [edited: formatting and signature]


 * Good information. Please don't forget to sign your contributions to talk pages. Kind regards, --Maffblaster (talk) 19:36, 25 July 2016 (UTC)


 * Thank you, I have found the relevant Gentoo guidelines (and I am trying to apply them). --Hamlet (talk) 20:31, 25 July 2016 (UTC)

Radeon Video Coding Engine firmware needed for HD7970 ()
Had messages in kernel log complaining about missing this firmware blob after switching from fglrx to radeon, the documentation on this page skips this firmware blob for the HD79XX series in the table. --_andyj_ (talk) 21:17, 25 Sept 2016 (UTC)
