Previous version used monitor identifiers if present, otherwise output
names. That caused existing working configurations to break when additional
information was added to the configuration file.
(cherry picked from commit 3f5cedf00a)
Screen physical size is set to a random value before the RandR code gets
control, override that and reset it to a value based on the compat_output
physical size (if available). If that output has no physical size, just use
96dpi as the default resolution and set the physical size as appropriate.
(cherry picked from commit 843077f23a)
xf86SetDesiredModes applies the desired modes to each crtc (as selected by
xf86InitialConfiguration initially and modified by successful mode settings
afterwards). For crtcs without a desired mode, pScrn->currentMode is used to
select something workable.
(cherry picked from commit bcade98cca)
This function applies a single mode to the screen (as from RandR 1.1,
XFree86-VidModeExtension or XFree86-DGA) using a policy that selects one
output to reconfigure to the requested mode and then makes all other outputs
fit within that size.
(cherry picked from commit 5a595c1f76)
Box transformation from source to dest area was broken, leaving the wrong
areas painted when the crtc origin was non-zero.
When rotating from left to right, the pixmap doesn't get reallocated, and so
no damage was left in the pixmap from xf86RotatePrepare. Separately damage
the whole crtc area when this occurs to repaint the area.

canGrow indicates to the DDX that the driver can enlarge the desktop via the
xf86_config->funcs->resize hook. If so, xf86InitialConfiguration will set
virtual[XY] to match the configuration it chooses and will leave the crtc config
size ranges alone. If FALSE, it will bloat the screen to fit the largest probed
mode and also set the crtc config max size to limit the desktop to the initial
virtual[XY] size.
This hook is called when the DDX needs to resize the screen. The driver is
responsible for changing virtualX and virtualY, along with any other related
screen properties (devPrivate.ptr, devKind, displayWidth, etc.).
Use the size range from the crtc config instead of randrp->virtual[XY] when
reporting the min and max screen sizes to the DDX.
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.
