This fixed the crash appearing for Xv buffer memory, which appears
allocation and free happening in stolen memory. We should always
try to bind for stolen memory for correct protect setup, otherwise
we might get fault that stolen memory protect reverted to non-r/w
after previous free and unbind.
Credit goes to Lukas Hejtmanek to identify the real problem of Xv
crash!

This lets us get better sanity asserts, and avoid mysterious braces when you
do two BEGIN_LP_RING()s in a single function. Potential minor performance
loss isn't too exciting, as ring access is about to become a compat path
anyway. This change also removes the requirement for ring emits to be aligned
to dwords.

I want to hack on i830 for changing it into a compat path for batchbuffer
without having to worry about the i810 stuff getting broken.

Tested by Dan Williams.

Fixes the build for me (just following the git development guide on a
new machine).
|
|
Needed for new uint* usage.
|
|
Fixes #15036.
|
|
Unbind and bind a DRM BO may change the buffer offset, thus
crtc may reference a wrong rotated memory after a VT switch cycle.
Destroying it here will cause its reallocation when entering VT.

Several uses are actually left, which are determined by the X Server
interfaces we're implementing.

Fixes #14944.

Fix printf formatting warnings, wrap a couple of long lines, nuke
unused variables, add missing #include <unistd.h>.

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.

Fixes #14888.

This will likely fix SDVO outputs on G35 hardware.
|
|
Based on Maxim Levitsky's patch for the same. Many thanks to Maxim for
discovering that this features still works in recent hardware!

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).
|
|
And directRenderingDisabled already has config check result.

When we reserve memory (memory that won't be managed by the kernel) make
sure to reserve space for the FBC LL cache as well.

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 3c22ed633be2ac96eea7bc533839e956f1f31b84 (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.
|
|
Track current covered crtc rotation in port's private,
and fix overlay rotation transform to be against crtc mode
coordinate.

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.
|
|
ThinkPad X40s need this quirk or they'll crash frequently.
Fixes #14521.
|
|
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.

My fault to change Hong's origin patch reversely.

Z61 has same subsys ids with X60, but does have one S-video
TV out. Use DMI info instead to quirk TV on X60, X60s.
|
|
Linux kernel has CONFIG_DMIID to export dmi info
through sysfs.

For i830M stolen mem size mask should always be 0x70.
Use 0xF0 for later chipsets should be ok, so behavior is
identical to kernel agp.

The call to disable FBC should only occur if the FBC feature is actually
present or we may end up hanging on a read from a non-existent register.
