[lfs-support] Adding firmware to the kernel
My latest machine has an ATI 760G (Radeon 3000) video controller. According to dmesg, it is trying to load R600_rlc.bin for KMS. So, I got the firmware, and put it in firmware/radeon/ in the kernel tree. But it doesn't find it (this is without an initrd). My config includes CONFIG_FIRMWARE_IN_KERNEL=y CONFIG_EXTRA_FIRMWARE=R600_rlc.bin CONFIG_EXTRA_FIRMWARE_DIR=firmware/radeon/ Any idea what I'm doing wrong, please ? ĸen -- das eine Mal als Tragödie, das andere Mal als Farce -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page

The only thing I can suggest is perhaps the kernel is looking for radeon/R600_rlc.bin? Try setting it like this: CONFIG_EXTRA_FIRMWARE=radeon/R600_rlc.bin CONFIG_EXTRA_FIRMWARE_DIR=firmware This works for me (with a different Radeon card): # CONFIG_PREVENT_FIRMWARE_BUILD is not set CONFIG_FW_LOADER=y CONFIG_FIRMWARE_IN_KERNEL=y CONFIG_EXTRA_FIRMWARE=radeon/BARTS_mc.bin radeon/BARTS_me.bin radeon/BARTS_pfp.bin radeon/BTC_rlc.bin CONFIG_EXTRA_FIRMWARE_DIR=/lib/firmware Andy -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page

Looks as if there is a problem with putting the full directory name in the directory part. For ubuntu, they will be loading it into the initrd. CONFIG_FW_LOADER is apparently so that userspace can load (some) firmware.
