The hook is called whenever the clipList of any DRI window changes, be it via
DRIClipNotify, DRICreateDrawable or DRIDrawablePrivDelete. This allows the
driver to keep track of which DRI windows are visible where.
in xf86CrtcSetMode, scrn->pScreen will be NULL during server startup time,
so don't try to set the subpixel order. subpixel order will be set in the
randr initialization anyways.
(cherry picked from commit 5f6f8616d8)
New modes header files required a few minor changes to be used by external
drivers, the most notable of which is the publication of the config file
parser header files.
Add monitor "Rotate" option taking one of "normal", "left", "inverted" or
"right". However, because initial mode selection is made before the screen
is completely initialized, we cannot create the shadow pixmap object at this
point. Pend the shadow pixmap creation until the block handler.
Note that this code is not completely functional yet.
Code added in hw/xfree86/modes came from the server-1.3-branch.
Portions of this code had previously been integrated into xf86Mode.c
and edid_modes.c.
To preserve hw/xfree86/modes as much as possible, the duplicate code from
the other files has been disabled; a more careful review would figure out
where that code actually belonged.
RandR 1.0 sizeID must be computed the same way every time, so when reporting
it in the ScreenChangeNotify event, just construct the usual 1.0 data block
and use that.
subpixel geometry information can be computed by looking at the connected
outputs and finding any with subpixel geometry and using one of those for
the global screen subpixel geometry. This might be improved by reporting
None if more than one screen has information and they conflict.
This code comes from the intel driver, so there's no history in this tree.
As the crtc/output-based mode selection code uses ddc, the ddc and i2c
modules have been merged into the server. Attempts to load them are safely
ignored now.
This instruction is being used in some debug VBIOSes. This implementation
doesn't even try to be accurate. Instead, it just increments the counter by a
fixed amount every time an rdtsc instruction in encountered, to avoid divides by
zero.
Our modes typically come from EDID or default modes, and when the monitor
asks for a specific mode, deciding to tweak it usually results in incorrect
display. And if the user is specifying a mode by hand, tweaking it then is
still pretty rude.

Currently, the call to linuxPciOpenFile() is always made for read
only access which causes the subsequent mmap call to fail when the
memory is mapped read/write.
Xorg #9692
The fbdev API doesn't allow setting the pitch explicitly, so we have to set
the virtual width to the pitch we're using for drawing. This fixes corruption
after changing the virtual width with RandR.
The fbdev API allows the driver to 'accept' modes it doesn't really support by
modifying it to the nearest supported mode. Without this check, e.g. vesafb
would appear to accept all modes, even though it actually can't set any modes
other than the bootup mode at all.
This has been what has been used the most successfully post-damagetrack.
The current thinking is that:
1) We should be able to accelerate basically everything. So we don't need to
try to migrate trees of pixmaps permanently out of framebuffer to speed
CPU drawing up.
2) Migration is cheaper in the thrashing case, so we don't want to go to a lot
of effort to try (and fail badly) to find a working set.
