  • hello,

    i've tried enabling support for GvT (gpu virtualization technology) in i915.conf on my manjaro system. But, for some reason, my pc doesn't start after that. It gets stuck in the user space. Disabling it again  makes everything work fine.  I'm running kernel 4.18.11, but this issue has been persisting since kernel 4.17.

     

    the contents of `/etc/modprobe.d/i915.conf` are as follows :

    ```

    options i915 enable_guc=3
    #options i915 enable_fbc=1
    #options i915 enable_gvt=1
    options i915 fastboot=1
     

    ```

    this is the output of `ls -al /lib/firmware/i915/`

    ```
