Thanks for the word of encouragement.
Yes, I am currently trying to make OpenChrome to be as automatic as possible
when it comes to display detection.
Previously, OpenChrome relied too much on a large known device table to figure
out what display resources the given hardware has, and it was becoming very
difficult to maintain reliable allocation of display resources if this practice
continued.
I finally removed this "known device table" entirely (it is completely gone
from via_id.c), and due to code maintenance reason, I also removed "legacy"
mode setting and VESA BIOS Extension (VBE) mode setting support.
This version will likely be called OpenChrome Version 0.4.0 due to the fact
that it does not support these "legacy" features.
However, several people have reported issues with DVI, and the work to fix
DVI related code is taking much longer than I originally anticipated, so in the
mean time, I will likely reverse some of these "legacy" option removal
activities for now, and release OpenChrome Version 0.3.4 with DVI mostly not
working.
The code to support VT1632A TMDS (DVI) transmitter based DVI port will be
disabled for Version 0.3.4.
You can weigh in over here.
https://bugs.freedesktop.org/show_bug.cgi?id=94130
After that, I will resume the legacy code removal, and call this version
OpenChrome Version 0.4.0.
The fix for DVI will come around Version 0.4.1 or 0.4.2.
The current OpenChrome works fine with x.org X server 1.7 or later and Linux
2.6.32 or later (i.e., Ubuntu 10.04 and related OSes), but it does not work
well with older Linux kernel probably due to a rumored DRM bug in the older
Linux kernels.
I will continue to test the code against Ubuntu 10.04 for the foreseeable
future.
Regarding CLE266, the current code has a bug with ACPI S3 State resume, and
I eventually plan to work on a fix for this bug, but it is somewhat of a low to
medium priority item at this point (fixing DVI is the most urgent).
I do understand that people still use old computer hardware, and obviously
CLE266 will continued to be supported.
I do have 2 mainboards with CLE266 (EPIA based), and I test it regularly with
one of them (i.e., EPIA-M).
In addition to the existing OpenChrome, Ran "Frank" Huang and I are in the
process of reviving long forgotten (only one year though) DRM (Direct Rendering
Manager) module for VIA Technologies IGPs originally written by James Simmons.
Yes, it is to support KMS, and I think spending some resources on this is
probably necessary so that OpenChrome does not get dropped from Linux based
OSes in the near future.
At least, Frank and I have observed that the new DRM module is working fine
with VGA, but at least I have not tested it beyond VGA at this point.
Unfortunately, the way it is written currently, this developmental DRM module
requires Linux kernel 3.18 or later due to it using the latest TTM API.

Kevin Brace
