Hello,

Trying to set up an HP Pavilion 15z-cd000 laptop with an AMD A12-9720p (R7 Carrizo graphics)

Kernel is vanilla 4.15.14

I've followed the AMDGPU article in the wiki, but getting the following messages in dmesg and no video:

Code:
dmesg | grep gpu

The system doesn't lock up - Obviously, I get logs that I can review when I boot via USB. Also, I can ctrl+alt+del to reboot after a few seconds.

Kernel config:
http://meaninglessinfo.com/tech/meaningless_desktop/15z-cd000_kernel_cfg

Note, in that config, the firmware is not listed out in CONFIG_EXTRA_FIRMWARE - removed it just to see what would happen. Same error either way.

I'm probably overlooking something silly, but any advice/insight is appreciated!

Also maybe worth mentioning that the Sabayon live image boots just fine, but I can't work out what I'm doing wrong/differently.

error -2 means the file is not found.

That's slightly helpful, but not sure what I can do about it? I've installed linux-firmeware and can ls the directory - all the files are there.

Somehow I was also under the impression that when you did list those files in CONFIG_EXTRA_FIRMWARE, the firmware would be built into the kernel. However, I'm not sure what gave me that impression and as I said, filling out that setting seems to make no difference.

Thanks

EDIT: Trying again w/ that variable set. I think I may have done it wrong before....I now see it handling those files during the make process.

So...not sure what I did wrong before, but resetting CONFIG_EXTRA_FIRMWARE per the wiki seems to have resolved the issue.

I guess, if you're reading this having the same issue, make sure you set that variable correctly!

Thanks for the help Jaglover - it got the gears turning :)

Many drivers, when built into the kernel, will initialize before the filesystem is ready. If this is one of those, then it cannot use on-filesystem firmware even if you put the firmware in the right place. In those cases, your only choices are to build the firmware into the kernel (as you did) or to make the driver a module on the filesystem, so that it cannot be loaded or initialized until the filesystem is ready. In my opinion, your solution is the better choice.
