TAHITI firmware files needed for other So.I. chipsets?

Talk status

This discussion is still ongoing.

The lists of firmware files needed for the Southern Islands chipsets (Cape Verde, Pitcairn, etc.) all include TAHITI_uvd.bin TAHITI_vce.bin, but I've booted a kernel without including those firmware files and it works fine, with no messages in dmesg or syslog about missing firmware. This could be specific to my hardware; I use a Radeon HD 7850 card. But could it be that the TAHITI files are not needed? The firmware file lists were copied from the radeon article, but I'm not sure if anyone has actually checked whether AMDGPU has the same firmware requirements.

Here are the revisions where the TAHITI files were introduced in the radeon article:

There are also discussions about this on the talk page for radeon:

Where is the Enable AMD powerplay component Option

Talk status

This discussion is still ongoing.

I filed a bug on bugs.gentoo asking what this option is called. I was referred here. I did try the kernel's search feature. I tried it with the gentoo-sources-4.9.x series which is what the user is using in this article. Thanks — The preceding unsigned comment was added by Ballsystemlord (talk • contribs)

Possibly more Firmware needed for Radeon RX5xx series

Talk status

This discussion is still ongoing.

It seems that the old listing is not enough - at least as of Kernel 4.17.15 and =sys-kernel/linux-firmware-20180730 these chips need more firmware at boot time. At least with the current setup boot failed with an active, but blank screen an mostly unresponsive system (I think it stalled like usual in this case for ~1 minute, then booted "headless" and I could REISUB).

New list for an RX560 should at least include amdgpu/polaris11_ce.bin amdgpu/polaris11_me_2.bin amdgpu/polaris11_pfp.bin amdgpu/polaris11_smc.bin amdgpu/polaris11_ce_2.bin amdgpu/polaris11_mec.bin amdgpu/polaris11_pfp_2.bin amdgpu/polaris11_smc_sk.bin amdgpu/polaris11_k_smc.bin amdgpu/polaris11_mec2.bin amdgpu/polaris11_rlc.bin amdgpu/polaris11_uvd.bin amdgpu/polaris11_mc.bin amdgpu/polaris11_mec2_2.bin amdgpu/polaris11_sdma.bin amdgpu/polaris11_vce.bin amdgpu/polaris11_me.bin amdgpu/polaris11_mec_2.bin amdgpu/polaris11_sdma1.bin

(Aug. 19th, 2018) I checked with this newly extended set of FW and it boots up nicely.

Those pesky kernel developers changed the menus again. ;) But, it is not much of a stretch to see the important options are now under the "Firmware loader" sub-menu. Such is the problem of documenting software, it is outdated the moment you publish it. --Grknight (talk) 20:57, 7 November 2018 (UTC)

Use flags

https://wiki.gentoo.org/wiki/AMDGPU#USE_flags

Package x11-drivers/xf86-video-amdgpu doesn't have any mentioned USE flag. `amdgpu` should be mensioned.

--Kreyren (talk) 12:12, 27 September 2018 (UTC)

x11-drivers/xf86-video-amdgpu does have a udev USE flag. Unfortunately, this information is automatically generated and cannot be added by hand. This keeps some data fresh as https://package.gentoo.org update but is far from perfect. --Grknight (talk) 20:54, 7 November 2018 (UTC)

Provide accurate informations!

To Brian Evans (Grknight) - https://wiki.gentoo.org/index.php?title=AMDGPU&diff=next&oldid=742192

Is missleading since this "fix" was proved as non-functional on mensioned bug.

Removed section that is no longer an issue as the offending version was removed. --Grknight (talk) 21:01, 7 November 2018 (UTC)
