Add KabyLake firmware. #160

Closed daniloegea closed 7 years ago

daniloegea commented 7 years ago

Add firmware for Kabylake family. Inspired by #151 Not sure if it's working but it's loading at least:

[drm] Supports vblank timestamp caching Rev 2 (21.10.2013). [drm] Driver supports precise vblank timestamp query. [drm] Finished loading i915/kbl_dmc_ver1_01.bin (v1.1) [drm] Connector eDP-1: get mode from tunables: [drm] - kern.vt.fb.modes.eDP-1 [drm] - kern.vt.fb.default_mode [drm] Connector HDMI-A-1: get mode from tunables: [drm] - kern.vt.fb.modes.HDMI-A-1 [drm] - kern.vt.fb.default_mode [drm] Connector DP-1: get mode from tunables: [drm] - kern.vt.fb.modes.DP-1 [drm] - kern.vt.fb.default_mode [drm] GuC firmware load skipped [drm:i915_setup_sysfs] RC6 residency sysfs setup failed [drm] Initialized i915 1.6.0 20160919 for drmn on minor 0 linux_pci_find failed!

hrm, i'm able to get it to load on my system looks like similar error i'm getting in #151 :

$ sudo dmesg|egrep -i dmc||guc
[drm:intel_csr_ucode_init] Loading i915/kbl_dmc_ver1_01.bin
i915/kbl_dmc_ver1_01.bin: could not load firmware image, error 2

Hi, try to load the firmware first (dmc and guc) and i915kms after that.

pewright-tronc commented 7 years ago

How are you loading the i915kms and fw modules? I have setup my rc.conf like so:

$ grep kld_list /etc/rc.conf
kld_list="i915_kbl_guc_ver9_14.bin i915kms if_iwm"

pre-pending the GuC fw module still results in an error while loading. are you loading it via loader.conf? oddly on my skylake system simply adding i915kms to my kld_list results in both the GuC and DMC getting loaded as expected.

daniloegea commented 7 years ago

I'm loading manually :sweat_smile:

Probably some dependency declaration is missing.

pewright-tronc commented 7 years ago

thanks that's helpful - i'll try to reproduce on my end and report back any additional info i dig up.

pewright-tronc commented 7 years ago

so yea, manually loading modules before i915kms and I'm still unable to load the GuC blob (with same error message). DMC loads - regardless if i manually load it or if i load i915kms first which will pull in DMC. not sure i know a good method to debug GuC not loading, so any pointers would be helpful!
