We wish it wouldn't, but the hardware ignores the alpha in the
BorderColor we set when the source picture format has no alpha
in it, (and it uses alpha of 1.0 where we want 0.0). For now,
fallback for these cases. This gives a correct result, but
obviously is not as fast as we would like.
This fixes bug #16820:
[EXA] Composition result in black for areas outside of source-surface bounds

I required the following patch on top of this to work around libpciaccess
brokenness. libpciaccess reports 0 rom size if there's no rom resource,
even if the rom file exists in sysfs.
libpciaccess (and the old X server PCI code as well) provides a function to
get the ROM contents. Code to use that was already present in the driver and
used if the INT10 function failed. Skip the INT10 and just use libpciaccess
as that eliminates several module loads and scary use of vm86.

Eric informed me that the repeat field exists only for backwards
compatibility with old drivers that weren't prepared for values
other than 0 or 1 here. Since we are, we can just ignore that
field and examine only repeatType. So the code's a (tiny) bit
simpler this way.
It's quite simple to support these modes---we simply need to
turn on the support for them in the hardware.
These changes have been verified with the extend-pad and
extend-reflect tests in cairo's test suite. However, this
currently required using a custom-modified version of cairo.
The issue is that released versions of cairo, (and even
cairo master so far), don't pass RepeatPad and RepeatReflect
to Render, (due to various bugs and workarounds in cairo
and pixman). I do plan to fix those issues in cairo, so that
in a future release of cairo, (1.8.2 perhaps?), the cairo
test suite will usefully test these new repeat modes in our
driver.
The existing switch statement was switching on the Boolean
repeat field rather than the correct repeatType field. This
had not caused any problem before as only two possible repeat
values were supported (RepeatNone = 0 and RepeatNormal = 1)
so they were always the same as the repeat field.
Soon, however, we'll be supporting more repeat types, so we'll
need to switch on the correct value.
From the Intel 965 Programmer’s Reference Manual, volume 3,
chapter 2.2.2 "Mode Switch Programming Sequence".
The disable sequence should be:
- Disable planes (VGA or hires)
- Disable pipe
- Disable VGA display in 0x71400 bit 31
This patch implements that order plus waits for a vblank at the end.
Fixes bug #17756.
Dump more panel data, including number of expected entries. Had to
refactor things a bit, but now each function should get size information
so further checking can be added more easily.
On some machines it appears that the LFP info pointers give us more
accurate panel info than if we index into the LFP data table using the
panel type index. Early reports indicate that using the pointers
doesn't cause regressions, so switch to them by default to help 8xx
machines.
Fixes bug 17310 (and hopefully 17658 too).
GCC isn't smart enough to analyze the control flow and figure out that
these are false positives, but initializing them shouldn't hurt, so work
around it.
Some ADD2 card doesn't get SDVO detect status setup right,
which disabled outputs on those cards. This adds a new
option "ForceSDVODetect" to probe all SDVO ports anyway.
On DVI, centered VGA mode is used instead of native mode VGA, and
PLL on pipe is used instead of VGA PLL setting. So make sure PLL
settled down in restore time.
For CRT this trys to probe all possible port for EDID and
detects got confirmed by EDID's d/a type bit.
For HDMI/DVI, also using EDID d/a type bit to ensure it should
handle the connect or not.
Oh duh (i830_video.c):
/* Clamp dst width & height to 7x of src (overlay limit) */
if(drw_w > (src_w * 7))
drw_w = src_w * 7;
if(drw_h > (src_h * 7))
drw_h = src_h * 7;
The condition I see in the documentation appears to be src_h/drw_h < 8, that
is, src_h < 8*drw_h. It appears this was "fixed" incorrectly in e784e152.
It seems difficult to believe that this limitation would exist at all for the
texture unit.
Unfortunate mismatch between kernel and DRM master headers.
Kernel:
typedef struct _drm_i915_batchbuffer { ... } drm_i915_batchbuffer_t;
DRM master:
typedef struct drm_i915_batchbuffer { ... } drm_i915_batchbuffer_t;
so use the typedef rather than the morphing structure name.
