This slipped in as a debugging aid, and never got turned off. The driver
appears to work fine without it on an i915 system, and for the non-default EXA
option, we'd rather see issues found than continue running with debugging aids
and hiding them behind bad performance.

This allows setting the size to 0 when a pipe gets disabled.

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.

This seems like a typo, which causes screen artifacts.

The now-generic (kind of) EXA code will be cleaned up and moved to generic
files in a later commit.
|
|
Previously, we tried to use 2 points instead of 3 to describe the source
rectangles, which mostly just worked for scaling.
|
|
|
|
For EXA, this requires version 2.1 of EXA to do rotation, as the VT switching
issues were too complicated otherwise.
|
|
A side effect is the reduction in vertex dispatch, which is nice.
|
|
This reduces max framebuffer width and increases max framebuffer height on
965, reduces max X/Y on pre-965 EXA (could have caused mis-rendering), and
increases max X/Y on 965 EXA (would have prevented acceleration).
|
|
Several new global functions were not put into the header file leading to
potential mismatches between declaration and definition.
|
|
I830EntityIndex is shared between 810 and newer driver.
Move most EXA rendering state into I830 structure.
Declare shared variables in shared header files rather than .c.

Not split offscreen mem for exa, but alloc a dedicated one
for G965 states.

NULL vs. 0
make some variables static
remove redundant variables
There are only a few sparse warnings left now: some bitfield warnings
and a few 'mixing code and declarations' warnings from the ring macros.

This does not include ps program, which will be added
in g4a form.

Autodetect libdrm version, disable new memory manager on older libraries.
Move new M_T_ defines from i830.h to i830_xf86Crtc.h. Add many system
headers to define functions. Use i830PipeSetBase at end of mode setting
code to set DSP*BASE and flush changes. Don't duplicate PipeSetBase call
from screen init function. Make initial RandR configuration code usable on
older versions of extension so the server doesn't start in a panning mode.
Use xfree instead of free in i830_tv.c.

This replaces other debug sync options sprinkled around the EXA code. It
doesn't change the mis-rendering of text on the 915.

The I830Sync version has additional code for the 965.

Replace COLOR_BLT_CMD with XY_COLOR_BLT_CMD, by which
device would care for direction and provide a (x,y) coord
interface. This fixes pixmap artifacts even in no composite
case.
