Whoa, gcc got a lot smarter about warnings. If iXXX_get_dest_format()
doesn't support the picture format passed in it won't initialize the
uint32_t pointed to by dst_format and return FALSE.
What gcc now can detect is if dst_format is used without checking the
return value, it might be used uninitialized. This patch makes sure
we always check the return value before using dst_format.
This should keep the backlight value reported by xrandr --prop & xbacklight
consistent with changes by other software in the system (like the hotkey driver
or kernel backlight driver).
This simplifies the memory allocation code and fixes a number of bugs.
Prior to this change, some flags may have been set after memory
allocation occurred, meaning they had no effect. It should also make
the allocation logic clearer.
The following patch fixes the display problem on internal development machines.
The code in commit 3c22ed633b (Jesse's force pipe
A enable patch) broke DPLL programming. Moving the DPLL set back up in the
function solves the problem.
Fix for internal bug #309.
Use the "immediate idle" mode for FBC. Rather than waiting for the current
compression pass to finish before signalling to the CPU that it's idle, this
mode should stop any current compression pass and tell the CPU that the GPU is
idle right away.
Seems to fix#13326.
We failed to include the pciaccess header flags in our build. Even if the
server was to include those flags for us, it would leave us broken for the
tools-only case, and it's easier to just put the flags everywhere so we avoid
future copy'n'paste mistakes.
The GMBUS was being left in SDVO pin access mode, which blocked our bit-banging
access to those pins. Thanks to Peter Jones for quick debugging turnaround
in getting this fixed.
Some machines want DVOA, some DVOB. We can use this quirk to differentiate
them until we come up with a better solution. Patch from Hong Liu.
Fixes#13722.
The VGA register dumping code was leaving ARX in data mode rather than index
mode, which could cause problems for later software accessing AR* registers.
Fix it to make sure it's in index mode when we're done.
Fixes#14434.
When checking which pipe a given plane was associated with, we weren't properly
masking the pipe selection bits. Fixes#14481 and should allow the driver to
work with vesafb again.
Use PRIx32 for printing CARD32 types, and PRIx64 for portably printing uint64_t
types. Requires the addition of a new include, inttypes.h, to work. Hope C99
is ok with everybody...
Some chips can't support FBC if multiple pipes are active. So if more than one
pipe is on or we're going from one->two pipes enabled, make sure FBC is
disabled.
Intended to fix 13418, 13326, 13152.
We use the wrong DVO output register for ivch which is used for DVO LVDS.
Vbios enables DVOB and driver never touches it, so everything seems
working correctly now.
