Bug ID: 74911
Summary: [R9 270X] - Frozen display output and no response from
keyboard right after loading kernel image and
initramfs
Product: Drivers
Version: 2.5
Kernel Version: 3.15.0-rc2
Hardware: x86-64
OS: Linux
Tree: Mainline
Status: NEW
Severity: high
Priority: P1
Component: Video(DRI - non Intel)
Assignee: drivers_video-dri@kernel-bugs.osdl.org
Reporter: combuster@archlinux.us
Regression: No
After booting 3.15.0-rc2 kernel, I can only see a message from grub indicating
that kernel and initram images are loaded and that's it. No response from
keyboard, I can only do a hard reset.
After bisecting this is what I get:
1ebe92802eaf0569784dce843bc28a78842d236c is the first bad commit

drm/radeon: add support for newer mc ucode on SI (v2)
May fix stability issues with some newer cards.
v2: print out mc firmware version used and size

This makes sense, there is no radeon/PITCAIRN_mc2.bin blob anywhere. At least
not in linux-firmware branch.
I have compiled radeon drivers into the kernel image itself, here is a relevant
config line:
CONFIG_EXTRA_FIRMWARE="radeon/PITCAIRN_ce.bin radeon/PITCAIRN_mc.bin
radeon/PITCAIRN_me.bin radeon/PITCAIRN_pfp.bin radeon/PITCAIRN_rlc.bin
radeon/PITCAIRN_smc.bin radeon/TAHITI_uvd.bin"

How long have you waited for? Trying to load a non-existent firmware file may
only time out after a minute or so.

You can get it e.g. from:
http://people.freedesktop.org/~agd5f/radeon_ucode/
> I have compiled radeon drivers into the kernel image itself, [...]
It's recommended to build the radeon driver as a module instead and let the
firmware files be loaded from the initrd or normal filesystem.

I've left it once for a while, but I'll test for how long and report back,
seems to me it was about 4min.

Well, if it was recommended I haven't saw that recommendation anywhere. Used to
build an intel driver into kernel image itself, KMS kicks in as early as
possible. I did the same with radeon, and it works for me great this whole
time.
Don't mean to be rude or anything, but I don't know if it is recommended (or
desirable) to commit a piece of code to mainline that will _require_ a blob
that can't be found in linux-firmware ?
I'll see about the timeout and report back in.
Thanks Michel

Works now, 3.15.0-rc3 - no problems with the PITCAIRN_mc2.bin copied in
/usr/lib/modules/firmware/radeon.
Thanks Michel for clarification and help.
I won't touch the status of the bug report since I don't know if this one
should be marked as resolved untill mc2 parts hit the linux-firmware branch.

Yep, that timeout is one of the biggest downsides of building the driver into
the kernel instead of as a module.
I'd say there's no bug here, at least not in the radeon driver.

The radeon driver has always required microcode for some functionality.
