using non-free radeon firmware with a libre kernel base

[Christopher Howard]

I imagine that subject line will get me booted from this list, but I'm
stuck between a rock and hardplace. I want OpenGL support (and
eventually OpenCL). /Every/ single Radeon card requires non-free
firmware. What else can I do?

I wanted to use the libre kernel as a base, though, so I didn't get a
whole bunch of other non-free stuff included. I've done everything I
think needs to be done to get this to work:

1. Installed radeon-ucode into /lib/firmware/radeon through a distro
package.

2. Set config:

CONFIG_FW_LOADER=y
CONFIG_FIRMWARE_IN_KERNEL=y
CONFIG_EXTRA_FIRMWARE="radeon/ARUBA_me.bin radeon/ARUBA_pfp.bin
radeon/ARUBA_rlc.bin radeon/BARTS_mc.bin radeon/BARTS_me.bin
radeon/BARTS_pfp.bin radeon/BTC_rlc.bin radeon/CAICOS_mc.bin
radeon/CAICOS_me.bin radeon/CAICOS_pfp.bin radeon/CAYMAN_mc.bin
radeon/CAYMAN_me.bin radeon/CAYMAN_pfp.bin radeon/CAYMAN_rlc.bin

radeon/REDWOOD_rlc.bin radeon/RS600_cp.bin radeon/RS690_cp.bin

radeon/RV610_pfp.bin radeon/RV620_me.bin radeon/RV620_pfp.bin
radeon/RV630_me.bin radeon/RV630_pfp.bin radeon/RV635_me.bin
radeon/RV635_pfp.bin radeon/RV670_me.bin radeon/RV670_pfp.bin
radeon/RV710_me.bin radeon/RV710_pfp.bin radeon/RV710_uvd.bin

radeon/TAHITI_rlc.bin radeon/TAHITI_uvd.bin radeon/TURKS_mc.bin
radeon/TURKS_me.bin radeon/TURKS_pfp.bin radeon/VERDE_ce.bin
radeon/VERDE_mc.bin radeon/VERDE_me.bin radeon/VERDE_pfp.bin
radeon/VERDE_rlc.bin"
CONFIG_EXTRA_FIRMWARE_DIR="/lib/firmware"

I can see these firmwares being built when I run Make. Yet, I still get
this error:

[   25.802779] [drm] Setting GART location based on new memory map
[   25.803386] [drm] Loading RS780 CP Microcode
[   25.803392] r600_cp.0: Missing Free firmware
[   25.806729] [drm:r600_do_init_cp] *ERROR* Failed to load firmware!

In summary, I was wondering if libre adjustments to the kernel do
anything else to the configuration that I need to fix in order for this
to work.
