Summary: Radeon fails to load firmware Product: Drivers Version: 2.5 Kernel Version: 3.0-rc2 Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) AssignedTo: drivers_video-dri@kernel-bugs.osdl.org ReportedBy: cloos@jhcloos.com Regression: Yes
This used to work, but I had been booting with radeon.modset=0 for a few weeks, so I do not know when it broke.
With 3.0-rc2 (compiled from git master) I get (note this first two lines):

--- Comment #1 from Andrew Morton akpm@linux-foundation.org 2011-06-06 23:59:54 --- If it was Ok a couple of weeks ago then I assume that this is a psot-2.6.39 regression?

--- Comment #2 from James Cloos cloos@jhcloos.com 2011-06-07 00:47:29 --- Longer than that.
The box is usually headless; when I first got it the missing firmware prevented booting, so I added radeon.modeset=0 to the grub config and manually changed that for those occasions when I moved the box to the TV. Today I changed the grub config in honour of the upcoming 3.0. ☺
(That it boots now even though it fails to load that firmware is a nice progression.)
My best guess, based on the timestamps of my .config archive, is that I last connected it to the TV during the 38-rc1 timeframe.

--- Comment #3 from James Cloos cloos@jhcloos.com 2011-06-07 00:53:41 --- I forgot to add:
I don’t see from git-grep(1)ing the tree where or how the kernel knows to find firmware in /lib/firmware.
All I can see is /lib/firmware as the target to make firmware_install and several comments specifying /lib/firmware as the typical location.
What am I missing?

--- Comment #4 from Alex Deucher alexdeucher@gmail.com 2011-06-07 02:17:36 --- Most likely you did not include the firmware in your initrd.

--- Comment #5 from James Cloos cloos@jhcloos.com 2011-06-07 04:01:31 --- Ah. OK. The driver tries to load the firmware before / is mounted, then?
As I do not use initrd there the answer seems to be:
-CONFIG_EXTRA_FIRMWARE="" +CONFIG_EXTRA_FIRMWARE="radeon/R600_rlc.bin" +CONFIG_EXTRA_FIRMWARE_DIR="/lib/firmware"
to the .config.
Closing as invalid. Will reopen if the above .config change doesn’t fix it.
(Last time I must have manually done what EXTRA_FIRMWARE does. I lost that clone in the meantime, though, so that is only a guess. (It was a clone of my local, pristine clone. And the .configs were backed up in their own git repo. So that loss didn’t seem like much of a nuisance. But I obviously forgot about this issue in the meantime. ☹)
