The LVDS config bits in VBT driver feature block is used by vendor
to identify the board implement of integrated LVDS/eDP or SDVO LVDS.
And video bios uses these bits for LVDS enabling or not. So check
these bits for integrated LVDS might eliminate more quirks.
Instead of set control bus switch before every i2c start,
just set once before doing DDC. This should eliminate some
encoders returning error during that.
As SDVO TV uses SDVO_TVClkIn from SDVO encoder for clock reference,
it needs to generate proper PLL for current input clock. This uses
fixed PLL table from vbios for this. And possible sdvo mulitiplier
has to be setup correctly. This makes TV output stable on my 945GCLF2
board with NTSC-M format.
SDVO HDMI encode and audio is not setup in detect,
which fails in hotplug case for HDMI audio. Fix to
check current encode type and set flag for HDMI audio
enabling.
Check and set HDMI encode state in get_modes.
commit id b9f5915ce812144ffd9d2aa42e8ba856129c35e,
which resolved bug #17235, but generate new regression-bug #19715.
This patch intends to resolve bug #17235, and avoid regression as well.
We have successfully re-tested it for bug #17235 and #19715 respectively.
This adds back the resize hook so we can resize the front buffer under
kernel mode setting as well.
The patch also pulls the drmmode_* structs from drmmode_display.h into
drmmode_display.c and eliminates the header file.
Set alignments, tile settings and flags correctly in the 2D driver to support
tiled rendering. UXA's create pixmap function currently assumes the worst
about the alignment constraints; that should probably be fixed. Some of the
1M alignment fixes could probably be done more cleanly as well.
They're tiny so it shouldn't have been a problem, but play it safe. This is
another <5% loss on top of the previously reported value, bringing the whole
series to about 8%.
Several VBT modes out in the wild have H or VSyncEnd values greater than
the H or VTotal value. This clearly ends up creating a bad mode,
causing some panels to either ignore the timing or display some sort of
corrupt image.
Check for these cases and fix them up by default, making things work for
several Dell and Sony machines.
Fixes FDO bug #17292.
This is a first step in a series of changes to avoid requiring a pinned object,
which gets in the way of doing non-root KMS. This change appears to result in
about a 2-6% loss in x11perf -aa10text, which better algorithms in libdrm could
make up for (it hasn't really had to deal with code this bad before).
