full dmesg logs

CPU: Coffee Lake 8700K
Mobo: ASUS Z370-G STRIX
Distro: Arch
Kernel: 4.16.6-1-ARCH

The GuC firmware loads fine when I use the i915.enable_guc=1 kernel mode setting, but when I try to enable HuC loading with i915.enable_guc=2 I get a guc_fw_xfer error during boot. My system boots but my display output is blank.

Here's the relevant excerpt from the boot logs (full dmesg log attached).

I'm using the latest Arch package for linux-firmware (linux-firmware 20180416.b562d2f-1) and the latest Arch kernel.

This is my first bug report so sorry if it's not right.

just the drm logs

We shouldn't request a bug report if you set unsafe parameters.
Comment 3 ryanboehning 2018-05-06 18:26:37 UTC 
How else are you supposed to enable the HuC and GuC?
Comment 4 Chris Wilson 2018-05-06 18:48:03 UTC 
Likely dupe of #105653
Comment 5 Jani Saarinen 2018-05-07 07:18:36 UTC 
Reported, agree duplicate?
Comment 6 Jani Saarinen 2018-05-08 06:50:33 UTC 
Reporter, do you agree this as duplicate?
Comment 7 ryanboehning 2018-05-08 14:03:03 UTC 
I'm not sure. There's two dmesg logs with "*ERROR* GuC firmware xfer error -110" in #105653. Aside from that line, the dmesg logs are quite different. It might be the same underlying bug, or it might be two (or three) bugs in the same piece of firmware. If you want to close this as a dup, I'm fine with that as long as my logs are copied to the #105653.
Comment 8 Jani Saarinen 2018-05-17 10:02:54 UTC 
Guc not really supported upstream, yet, closing.
