Hi, All
the following is the patch set that adds the default modes for LVDS in
KMS
mode. It is to solve the following bugs:
http://bugs.freedesktop.org/show_bug.cgi?id=20801
http://bugs.freedesktop.org/show_bug.cgi?id=21094
http://bugs.freedesktop.org/show_bug.cgi?id=21346
http://bugs.freedesktop.org/show_bug.cgi?id=21417
http://bugs.freedesktop.org/show_bug.cgi?id=21671
Patch 1/3: Add a private data for LVDS
When the connector type is LVDS, it will add a private data
that
can be used to store the LVDS panel limit. For example: hdisplay, vdisplay.
Patch 2/3: Get the LVDS panel limit and check whether the given modeline
is valid
Traverse the mode list returned by KMS kernel to get the LVDS
panel
limit. And the panel limit is used to check whether the given modeline is valid.
Patch 3/3: Add the default modes for the LVDS
This is similar to what we have done in UMS mode
a. When there exists the EDID, either find a DS_RANGES
block or replace a DS_VENDOR block , smashing it into a DS_RANGES block
with open refresh to match all the default modes.
b. When there is no EDID, we will construct a bogus EDID
and add a DS_RANGES block with open refresh to match all the default
modes
welcome the comments.
Best regards
Yakui
