Make the application of crtc desiredModes generic code instead of
per-driver by creating xf86SetDesiredModes from the code that was in EnterVT
and calling it.
Also, move the frame buffer clear until just before mode setting to make
sure things are mapped correctly.
Code to drive the global configuration from a single mode setting operation
(from RandR 1.1, XFree86-VidModeExtension or XFree86-DGA) has been included
in the X server now, so remove it from this driver.
Shadow pixmap contents are copied from the main frame buffer and contain
only the bits displayed by the crtc, not the whole frame buffer. The crtc
origin is always interpreted by the shadow copying code, the frame buffer
itself doesn't move.
Without this, the EXA code decides that the framebuffer is not in video
memory because it's not located between the start of video memory and the end
of EXA allocator memory. We should either have EXA let the driver decide if a
pointer is in video memory, or add a new field for "end of video memory" (not
just end of EXA offscreen allocation), but this fixes things for now.
Without this, the 965 DRI driver fell over when pitch * height wasn't
page-size aligned. Since the allocator only allocates at page-aligned offsets
anyway this shouldn't hurt us at all.
This lets us do memory allocation just once rather than having several passes
(as long as things succeed), avoids trouble with zaphod mode, and will let us
do better automatic sizing of allocations soon.
The previous allocator worked in multiple passes, with (at least) one of
setting up allocations, another to attempt to adjust those for tiling, and
then a pass to set up the offsets and fix them in memory.
The new allocator is simpler, allocating memory immediately if possible,
setting up tiling up front, and choosing offsets immediately. AGP memory
is only allocated to back actual memory used, saving some memory that would
have been allocated for padding previous. It will also allow dynamic freeing
and reallocation of memory, which will be useful for framebuffer resizing.
The pipe mode setting code needs to disable the panel fitter when using the
pipe for things other than LVDS output. The driver was checking for panel
fitter conflicts using bits that the 965 chipset defines for selecting which
pipe the panel fitter is connected to. However, on pre-965 hardware, the
panel fitter works only with pipe 1 and those bits returned 0.
The result was that when pipe 1 was using the panel fitter, configuring pipe
0 would disable the panel fitter.
The fix provided uses a model-specific test for the panel fitter pipe.
Always allow (but do not require) link to server sources so that needed
files can be included in the generated tar files.
Add remaining .g4a files and assembly output to distributed file lists.
xf86Modes.h file signals the availability of the new modes API in the
server; use that instead of counting on X server version numbers.
Also, finish eliminating use of local copies of those header files.
Start time rotation requires that the pixmap be created after the server has
initialized the screens. Delay the pixmap creation until the first block
handler invocation.
Additionally, don't attempt to set double-wide on the 965, where there is
no such thing any more (not that we'd ever see modes high enough to trigger
it).
