In 1.11.903, the list.h was renamed to xorg-list.h with a corresponding
change to all structures. As we carried local fixes to list.h and
extended functionality, just create our own list.h with a bit of
handwaving to protect us for the brief existence of xorg/include/list.h.

Added one configuration option --enable-glamor to control
whether use glamor. Added one new file intel_glamor.c to
wrap glamor egl API for intel driver's usage.
This commit doesn't really change the driver's control path.
It just adds necessary files for glamor and change some
configuration.

The premise is that switching between rings (i.e. the BLT and
RENDER rings) on SandyBridge imposes a large latency overhead whilst
rendering. The cause is that in order to switch rings, we need to split
the batch earlier than is desired and to add serialisation between the
rings. Both of which incur large overhead.
By switching to using a pure 3D blit engine (ok, not so pure as the BLT
engine still has uses for the core drawing model which can not be easily
represented without a combinatorial explosion of shaders) we can take
advantage of additional efficiencies, such as relative relocations, that
have been incorporated into recent hardware advances. However, even
older hardware performs better from avoiding the implicit context
switches and from the batching efficiency of the 3D pipeline...
But this is X, and PolyGlyphBlt still exists and remains in use. So for
the operations that are not worth accelerating in hardware, we introduce a
shadow buffer mechanism through out and reintroduce pixmap migration.
Doing this efficiently is the cornerstone of ensuring that we do exploit
the increased potential of recent hardware for running old applications and
environments (i.e. so that the latest and greatest chip is actually faster
than gen2!)
For the curious, sna is SandyBridge's New Acceleration. If you are
running older chipsets and welcome the performance increase offered by
this patch, then you may choose to call it Snazzy instead.

[Note the performance regression for ocitysmap comes from that we now
attempt to support rendering to and (more importantly) from large
surfaces. By enabling such operations is the only way to one day be
faster than purely using the CPU, in the meantime we suffer regression
due to the increased migration and aperture thrashing. The other couple
of regressions will be eliminated with improved span and shader support,
now that the framework for such is in place.]
The performance increase for Cairo completely overlooks the other
critical aspects of the architecture:
World of Padman:
gen3 (800x600): 57.5 -> 96.2
gen4 (800x600): 47.8 -> 74.6
gen6 (1366x768): 100.4 -> 140.3 [F15]
144.3 -> 146.4 [drm-intel-next]
x11perf (gen6);
aa10text: 3.47 -> 14.3 Mglyphs/s [unthrottled!]
copywinwin10: 1.66 -> 1.99 Mops/s
copywinpix10: 2.28 -> 2.98 Mops/s
And we do not have a good measure for how much improvement the reworking
of the fallback paths give, except that xterm is now over 4x faster...
PS: This depends upon the Xorg patchset "Remove the cacheing of the last
scratch PixmapRec" for correct invalidations of scratch Pixmaps (used by
the dix to implement SHM operations, used by chromium and gtk+ pixbufs.

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.

It was just confusing otherwise, (since the EXA code has all been
removed now).

Depending on new server means these are always present.
|

The developers of the driver don't ever run or test without XV. Don't do it.

We only have on acceleration architecture now, and you can always build it
if you're building the driver.

UXA has completely replaced EXA at this point. UXA is the same rendering
core as EXA, but relying on kernel memory management or a fake bufmgr instead
of trying to manage memory in the X Server.
|
|
While EXA/UXA aren't completely good replacements (see bugzilla for
performance and stability problems), we are pretty sure at this point that
it's the right way to go and that having multiple acceleration architectures
is getting in the way of producing a stable codebase.
