The kernel crashes frequently with graphical glitches. Add the following
|
|
|
|
|
to the kernel command line to prevent this:
|
|
|
|
|
|

|
|
|
i915.enable_psr=0 i915.enable_dc=0

NetBSD

|
|
|
------
|
|
|
|
|
|
|
|
|
|
NetBSD 10 requires the i915drmkms firmware to be installed, and the pms
|
|
|
|
|
module to be disabled.
|
|
|
|
|
|
|
|
|
|
Download the Linux firmware file from the URL below:
|
|
|
|
|
|
|
|
|
|
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/i915
|
|
|
|
|
|
|
|
|
|
The required filename can be found from dmesg, and should be copied to:
|
|
|
|
|
|
|
|
|
|
/libdata/firmware/i915drmkms/i915
|
|
|
|
|
|
|
|
|
|
The enable_psr setting should also be changed in /etc/sysctl.conf with
|
|
|
|
|
the following line:
|
|
|
|
|
|
|
|
|
|
hw.drm2.i915_modparams.enable_psr=0
|
|
|
|
|
|
|
|
|
|
Finally, the pms module should be disabled by adding the following to
|
|
|
|
|
the end of the /boot.cfg file:
|
|
|
|
|
|
|
|
|
|
userconf=disable pms*
|
