Hi, I took kib's patches from https://www.kib.kiev.ua/kib/drm/ and merged them into CURRENT (a couple of changes in vm). I also added my chipset id to pciids, i915 and agp. The merged/updated patch can be found here: http://blog.grem.de/bits/haswellgfx_20150106.patch I tested on amd64 on an Acer C720 Chromebook, tests were done using drm.debug=2. pciconf -lv vgapci0@pci0:0:2:0: class=0x030000 card=0x0a111025 chip=0x0a068086 rev=0x09 hdr=0x00 vendor = 'Intel Corporation' device = 'Haswell-ULT Integrated Graphics Controller' class = display subclass = VGA After loading the i915kms the screen goes blank, this is due to not detecting the LCD panel. If I connect a screen to HDMI out, the output is actually shown on the laptop's panel. It comes up in the wrong resolution, but can be corrected using xrandr (I had various results, but at some point after booting with HDMI connected I got the panel's physical resolution). Obviously vt is still garbled. I had some artefacts after starting X, those went away after launching Chrome (which got stuck for a few seconds after launch, then caused an error message on the console). After that I could play full screen video just fine. Hot-plug support seems to work in general. Trying to suspend the machine using acpiconf didn' work: [drm:KMS:pid11280:i915_suspend] starting suspend drmn0: GEM idle failed, resume might fail acpi0: device_suspend failed Power management doesn't work (the machine is running pretty hot), consumption is much higher than would you would normally see on this laptop: [root@flimsy /usr/src/sys/dev]# acpiconf -i batt Design capacity: 4030 mAh Last full capacity: 3877 mAh ...

With debug mode disabled I got a kernel panic on loading the driver, I didn't verify yet if this was due to an unclean build and if it is reproducible. -- Michael Gmelin
