Very Slow Keyboard Input On Haswell #39

Closed nomadlogic closed 8 years ago

nomadlogic commented 8 years ago

$ sysctl hw.model hw.model: Intel(R) Core(TM) i7-4600U CPU @ 2.10GHz $ uname -a FreeBSD pier 11.0-ALPHA5 FreeBSD 11.0-ALPHA5 #6 a76e358(drm-next-4.6)-dirty: Fri Jul 1 20:09:29 PDT 2016 root@srd0009:/usr/obj/usr/home/pwright/git/freebsd-base-graphics/sys/GENERIC amd64

When I load the i915kms module on this platform I get very slow keyboard input. The system is usable, but it takes several seconds for keyboard touches to update on the console. When I startx (doing "Xorg -configure") and then exit X keyboard inputs update as expected.

Does this not happen on HEAD? This does not strike me as a video driver issue, more likely a vt_fb issue.

So I am running the kernel and modules that ship with 11-ALPHA5 and am not seeing this behavior. I am going to do some more testing on my end and see if i can help debug this.

i can't reproduce - your first assumption about this being a vt_fb issue is most likely correct.
