Thank you for that suggestion, this works well!

We at HardenedBSD have an experimental branch that is kept up-to-date
with FreeBSD HEAD along with Jean-Sebastien's excellent work (and
HardenedBSD's awesomeness on top of that).

The code is here:

https://github.com/HardenedBSD/hardenedBSD-playground/tree/hardened/experimental/master-i915

Latest builds are here:

http://jenkins.hardenedbsd.org/builds/HardenedBSD-CURRENT-i915kms-amd64-LATEST/ISO-IMAGES/

The problem is not the stability of Haswell support, but more the
regressions on already supported GPUs.

Currently, there is one big regression:
https://github.com/freebsd/freebsd-base-graphics/issues/2

It takes seconds to panic a Sandybridge or Haswell (so I suppose Ivy
Bridge is impacted too).

Once this is fixed (and so far my attempts failed), I believe the patch
can go in -CURRENT. Haswell support won't be rock solid but anyway,
Linux 3.8, the base we use, had only initial support. Many bugfixes came
in Linux 3.9 and 3.10. Hopefully, we'll get there more quickly.

Haswell graphics (i915) still not in CURRENT

2016-02-24 Thread Carsten Kunze 
Hello,

Haswell graphics (i915) still seems not to be in CURRENT.  There is a suggested 
test procedure on

https://wiki.freebsd.org/Graphics/Update%20i915%20GPU%20driver%20to%20Linux%203.8

but currently I'm to busy with other projects to test this.

At the moment CURRENT can't be used on laptops with i915 graphics, so it may 
not harm to integrate a buggy i915 support in CURRENT.  The advantage would be 
that more users would test the driver and could give response.  This may speed 
up the debugging/testing of this driver.
