This is a simple patch to avoid cherry-picking all of
b5c9de10ba3a811f312e622b97ee5e601bd3b74f.
|

On failing to extract the pixel value for an alpha-only solid we
actually triggered a fallback. Since this path is commonly hitting
whilst fading in images, for example cairo_paint_with_alpha(), the
fallback was detected during the Moblin boot sequence where it was
adding a second to the overall boot time.
See
fallback intel: Moblin startup is hitting a composite fallback, costing
a ton of performance
https://bugs.freedesktop.org/show_bug.cgi?id=26189
Based on the initial patch by Arjan van de Van.

This apparently no longer exists in a KMS world, so remove it from the
documentation.
|
|
The old UMS name was PANEL_FITTING while the new KMS name is "scaling mode".
Fixes bug #25606.
|
|
The BACKLIGHT_CONTROL and PANEL_FITTING options appear in a list, and
then each contain a sub-list of sub-options. Use indentation to make
this structure more apparent to the reader.

For the second release-candidate snapshot in preparation for 2.10.
|
|
This comes from my cursory glance over the commit log from 2.9.1
to master.
|
|
These were added in 3c0815abf28744e215bea286e71d935cd486955a . The
documentation added here comes straight from that commit message.

The variable "intel" is unused when building i830_video.c without XvMC
support which results in a compiler warning:
i830_video.c: In function 'i830_copy_video_data':
i830_video.c:1443: warning: unused variable `intel'
Trivial fix via #ifdef.
|
|
Now that libdrm 2.4.16 is released (and already required) we can
unconditionally enable this.
Please add something like this to the release-notes/NEWS file:
* Overlay support for kernel modesetting. This needs at least kernel
v2.6.33 to work. A backport to 2.6.32 is available at:

This reverts commit 3f11bbec420080151406c203af292e55177e77d1.
For unknown reasons, enabling tiling for the glyph cache is causing
glyph corruption both across suspend and resume and VT switching, on a
wide range of chipsets (reports include both i8xx and gm45)
This strongly suggests that we are handling tiling, or updates to tiled
buffers, incorrectly across i915_gem_idle(). However, until we can find
the root cause, we want to fix this regression before the next stable
release, so simply revert this patch. :(

Maintain a small cache of pixmaps to hold SolidFill pictures. Currently
we create a pixmap the size of the damaged region and fill that using
pixman before downloading it to the GPU and compositing. Needless to say
this is extremely expensive compared to simply emitting the solid
colour. To mitigate this cost, we maintain a small cache of 1x1R
pictures which is recognised by the driver as being a solid, but at the
very least is maintained as a GPU ready pixmap.
This gives a good boost to cairo-xcb (which uses solid fills) on a gm45:
Before:
gnome-terminal-vim: 41.9s
After:
gnome-terminal-vim: 31.7s
Compare with using a cache of 1x1R pixmaps in cairo-xcb:
gnome-terminal-vim: 31.6s

This should restore the previous level of synchronisation between
textures and pixmaps, but *does not* guarantee that a texture will be
flushed before use. tfp should be fixed so that the ddx can submit the
batch if required to flush the pixmap.
A side-effect of this patch is to rename intel_batch_flush() to
intel_batch_submit() to reduce the confusion of executing a batch buffer
with that of emitting a MI_FLUSH.
Should fix the remaining rendering corruption involving tfp [inc compiz]:

In commit 98e11210
Remove flush parameter from intel_batch_flush()
Maxi spotted that I had broken screen updating. It appears in my haste
to eliminate the extra parameter I removed a call to intel_batch_flush()
when throttling, i.e. when pushing the updates to the screen before
idling.

If we wedge the GPU then we will return -EIO for the current batch and
then attempt to reset the GPU. Meanwhile the X server detects the error,
throws a FatalError and to all intents and purposes appears to crash to
the user - whereas before it often just appeared to momentarily freeze.
Of course, on older hardware the server remains frozen until we can find
a way to reset those GPUs at runtime.

Around a call to uxa_put_image() it is possible to mix both accelerated
and fallback paths, with the fallback code making the presumed
optimisation of only trying to call uxa_prepare_access() once. This
fails if the accelerated path also uses prepare/finish access on the
same drawable and then later fallback to the fallback path. This can
happen currently if an error is reported whilst attempting to accelerate
PutImage.

The kernel will only emit a flush iff the buffer is currently owned by
the GPU. Instead of presuming that the kernel must emit a flush, it is
safer to assume that it does not and so cannot mapping the buffer on to
the CPU as a synchronisation point. The most obvious counter-example is
when we map the same buffer twice without using it in a batch.

These files have been dropped from the generated tar file since the
removal of UMS support. However, the bios_reader code still includes
these, so "make distcheck" fails unless these are distributed.
There's probably a cleaner fix possible, but this at least fixes the
build so that the snapshot can be pushed out.

|
Since the UMS code has all been removed.

We plan to collect real release notes before the 2.10.0 release.

On older chipsets (i.e. pre-i965) tiling is very restrictive and imposes
severe size and alignment constraints. Combine that with relatively
small apertures and it is very easy to create a batch buffer that
cannot be mapped into the aperture (but would otherwise fit based purely
on total object size). To prevent this we need to not use tiling for large
buffers (the very same buffers where tiling would be of most benefit!).

When updating a buffer object for the framebuffer, we may need to
allocate a fresh pixmap private structure, for example if the pixmap is
replaced due to resize. When doing so it is then imperative to
initialise the circularly linked lists correctly.
