Hi,
I built an image myself from your github branch. I tried to run it.
Current status:
- Driver works ok for HDMI output, sometimes display is offset with a
large black area at the top (about 1/3 of the screen). Can't change
resolutions.
Status after your changes:
- Display is offset with a large black area at the top (tried only
once), and data is shifted horizontally (it seems like a mismatch
between resolution Haiku uses, and resolution the driver uses).
- No syslog, because it is entirely filled with AHCI errors from my CD
drive, to the point that nothing else was stored in the file. Guess
we'll have to fix that problem first (there is no disk in
the drive, so the AHCI code keeps resetting it until there is one).
Thanks for testing.. It turns out there is another layer of transceiver
registers that have to be programmed that we never have on pch-split gpus.
Not sure how intel_extreme was working as well as it was.. but this explains
why our intel_extreme always functioned poorly on pch-split devices like
Ivy Bridge :-)
Intel_extreme needs displayport support ASAP. Like on radeon_hd, newer laptops
are beginning to wire the LCD displays via display port internally.
(not that the radeon_hd displayport stuff well atm anyway :-\)
I've hit a bit of a wall over the holidays, but am slowing starting to
pick up development again... too many problems at the moment to merge
unfortunately. I did merge upstream into my branch though to make sure
I don't have any massive conflicts.
