Cristian, could you confirm which system you are using ? from bug 97826, it sounds this is a SandyBridge system and therefore you should not be affected by these warnings for APL/BXT & KBL platforms. As reference, you can find & download latest Intel firmware at: https://01.org/linuxgraphics/intel-linux-graphics-firmwares you can also notice that only the qualified GuC for SKL is available for download at that time. The initramfs-tools package tries to ensure all the firmware files potentially needed by kernel modules are included in the initrd. update-initramfs looks at the module firmware files reported by modinfo for i915.ko: $ modinfo -F firmware drivers/gpu/drm/i915/i915.ko i915/bxt_dmc_ver1_07.bin i915/skl_dmc_ver1_26.bin i915/kbl_dmc_ver1_01.bin i915/kbl_guc_ver9_14.bin i915/bxt_guc_ver8_7.bin i915/skl_guc_ver6_1.bin However, our driver supports hardware that hasn't been released yet, and we haven't released the firmware files either. We'll probably need to try to push the firmware releases earlier, but I suspect we won't get rid of the problem altogether. So closed as wontfix. Fill free to reopen if you need. Thanks. Now the hardware has been released, but there is still no GUC firmware for Kaby Lake in git or anywhere. I am typing this from a Kaby Lake Dell XPS 13 right now. Kernel installs report missing kbl_guc_ver9_14.bin. But the main concern is that Kaby Lake really uses 2x CPU when doing GPU-intensive things - e.g. rendering videos and other stuff in Google Chrome. My old Dell XPS 13 with Ivy Bridge is about 2x faster when put side by side. Can the missing GUC firmware be the reason for such slow down? Ubuntu 16.10 with latest graphics stack from 01.org.

Hi Anton, you can find latest FW on our website: https://01.org/linuxgraphics/downloads/firmware. Especially: https://01.org/linuxgraphics/downloads/kabylake-guc-9.14 So I am closing this bug since this is linked to missing guc which is available. If you have any other issue, please open a new bug with all necessary info. |
