dependencies. It was nearly abstract enough already to be used by
multiple DDXes. This will be useful for EXA development through
providing a fake acceleration implementation within Xephyr, so that
testing can be done on new EXA code without worrying about buggy
drivers.
the wrappers to provide it. Wrapper gone, and getsecs doesn't exist on
linux so it now blows up. Fixes it by just calling gettimeofday() in
all cases instead.
the generator routine: the allocated modeline wasn't nulled and
mode->name's \0 wasn't copied over. PrintModeLine was rewritten and
HDisplay gets rounded up to character width instead of refused.
Attempt to build xeglmodule.c, not xglxmodule.c.
Add xf86Sbus.h to EXTRA_DIST, as _HEADERS doesn't appear to get the same
treatment as _SOURCES in terms of automatically DISTing.
we only take it when clipping a DRI drawable instead of on every tree
update. Note drawable lock acquisition per- screen instead of globally,
and drop it in BlockHandler if necessary.
- add hw/xfree86/utils/cvt/, cvt.c, cvt.man.pre and Makefile.am.
- Adjust configure.ac and hw/xfree86/utils/Makefile.am for cvt.
- Add MonPtr->reducedblanking and Option "ReducedBlanking" to the Monitor
section.
- Check for reduced blanking in xf86CheckModeForMonitor and disallow modes
with less than 25% blanking otherwise.
- Fix some warnings in hw/xfree86/common/xf86Config.c.
mappings (including left-handed mouse etc.). Fixed incorrect usage of
non-reversed, but ZAxisMapped buttons for state detection. Nuked unused
part of reverseMap.
URL in log file for Xorg CVS. Also fixed wording of statement to not
refer to monolithic CVS since modular uses the same code, so it was
appearing in modular builds too.
screen size (display mode). Useful for faked widescreen modes, modes
which are scaled by the driver, etc. This really helps fixing RandR's
sometimes dumb DPI assumptions.
pixmaps's contents are undefined, so we won't need to upload the
undefined contents in MoveIn. Use the ExaCheck* for async ops as well,
so that dirty is always tracked. While the performance impact for my ls
-lR test was not significant (though the avoiding-upload path was being
hit), it's likely to be important for the upcoming Get/PutImage
acceleration from ajax.
Dist helper shell scripts.
Dist XAA.HOWTO and a few more unused C files.
Dist xorgconf.cpp.
Fix DIST_EXTRA typo.
Clean yacc and lex generated files only during make maintainer-clean as we
don't expect users to have those tools installed.
xf86DefModeSet.c with FreeBSD make, where RM was undefined. While here,
make the build of xf86DefModeSet.c depend on its sources, so it'll
rebuild properly, and make it a normal CLEANFILE rather than a
DISTCLEANFILE, since the intention seems to be to build it at the
user's build time.
causing our search loop for evictable blocks to possibly skip a good
candiate, and another was the allocator would occasionally use
area->offset as if it was the base of the pixmap, while for a pixmap
that is not in available state, it is not. This caused some funny
miscalculation leading to overlapping pixmaps and accesses beyond the
end of the framebuffer. To make things cleared, I renamed save_offset
to base_offset, made sure it's the one used everywhere in the
allocator, and only align "offset" for the client at the end of
exaOffscreenAlloc().
don't expect drivers to be able to accelerate without exa assistance).
Instead, drop back to plain old miGlyphs for a 62.5% +/- 1.5% reduction
in runtime of my ls -lR test (n=5) with component alpha. While a
reasonable approach would seem to be making a better test to see
whether the entire path would be accelerated and force migration
appropriately, my attempt at this made the situation much worse.
accelerate repeat NPOT thus triggering software fallback (this is the
case with gnome desktop for example). This adds a simple optimisation
to exa that removes "repeat" when it's obviously useless, that is, the
single picture instance covers the entire rectangle beeing used
instead of reporting "unrecognized option" when the argument is
missing. Also give correct error instead of "unrecognized option" for
options only available to root.
so resulted in a solid black glyph if the font rendering actually
resulted in a fallback (subpixel AA, for example) and the temporary got
migrated after 10 or so glyphs.
compatible with glibc, so the backtrace support check fails. Work
around this by wrapping the code in a configure check for execinfo.h,
and emulate detection for the monolith. (Yuri Vasilevski)
- Merge various fb/ bits of COMPOSITE support from xserver, which weren't
necessary before due to cw hiding the issues. Fixes offset calculations
for a number of operations, and may pull some fixes that cairo has
wanted for XAA as well.
- Add a new call, miDisableCompositeWrapper(), which a DDX can call to keep
cw from getting initialized from the damage code. While it would be
cleaner to have each DDX initialize it if it needs it, we don't have
control over all of them (e.g. nvidia).
- Use the miDisableCompositeWrapper() to keep cw from getting set up for
screens using EXA, because EXA is already aware of composite. Avoiding
cw improved performance 0-35% on operations tested by ajax in x11perf.
particularly thanks to Prepare/FinishAccess) to avoid DFS/memcpy on
pixmap move-out if it's unnecessary. This was disabled in KAA because
cache misuse on ATI made me guess that this code was wrong.
- Unwrap Glyphs on closescreen.
hw/xfree86/utils/ioport/Makefile.am
Add ioport and pcitweak utils from monolith hw/xfree86/etc dir.
Generate xf86DefModeSet.c from vesamodes & extramodes
Add apSolaris.shar to EXTRA_DIST
ChangeLog
include xorg-config.h for modular build
Adjust XF86CONFIG defines for modular build
Fixes for modular build:
- include modular server config headers
- change default XCONFIGFILE to xorg.conf
- define XKB_RULES_DIR if not defined by Imake
than the max, it was bumped, and then if you were above the threshhold
you got moved in. Instead, do the above-threshhold check separate from
score starting out less than max. While this will likely make thrashing
cases worse, I hope it will fix some issues with long term performance
(think of an xcompmgr with a backbuffer it's doing only accelerated
operations to. If some new pixmap comes in and bumps it out, even once,
it will never get a chance to re-migrate because its score will be
maxed). Change migration-out to be the same way for symmetry, though it
shouldn't ever affect anything.
- Fix a lot of debugging output, both in terms of printing quality, and
completeness. The fallback debugging covers a lot more now, pointing
out new areas for improvement. Debugging toggles are now centralized in
exaPriv.h.
example of this is the root weave, which paints slightly slower on SiS
now in my testing. However, according to keithp some apps use this
feature for a sort of cheap backing store, which this could help with
significantly. While I haven't done much performance testing with it,
it will at least rule out one possible source of terrible performance.
chown/chmod later. Also disable by default on platforms that don't need
setuid root X servers (Darwin & SPARC's, according to
InstallXserverSetUID settings in the old Imake config files).
hook so we can upload a subset of a pixmap, and convert the current
drivers to respect that. Use this support to directly UploadToScreen in
exaGlyphs, providing a 47.4% +/-2.4% decrease in wall time for ls -lR
programs/Xserver in an antialiased gnome-terminal on an M6 (n=3, caches
hot). I would have bumped major version, only I can't tell what the
EXA_VERSION_* is supposed to be doing as opposed to the module version.
RADEONHostDataBlit.
- Disable the shortcut for switching from 3d to 3d in radeon_exa.c. It
appears that we do need the cache flush here, thought it's not clear
why. Disable the 2d to 2d shortcut while here, since I'm unsure of what
we're doing. Exposed by the following bit:
- Bug #4485: Add a new routine, exaGlyphs, to handle font drawing. Glyphs
were being accumulated in from non-migratable scratch pixmaps, causing
the destination pixmap to move towards screen but the migration
necessary for source never to happen, leading to abysmal performance.
Instead, copy the scratch glyph data into a real pixmap first, then
composite from that into the destination, allowing for migration. time
ls -lR from programs/Xserver showed 26.9% (+/- 6.3%) decrease in wall
time (n=3).
- Create exaDrawableUse* wrapping exaPixmapUse*, but which are aware of
windows needing backing store. Makes migration code prettier, and
ensures that composited windows will be migrated as normal when we turn
off cw for EXA. (issue brought up by keithp)
module for FreeBSD by setting some missing defines (XFree86Module,
IN_MODULE) in the dri directory. Note that those missing defines should
be somewhere generic, since there are other consumers of them, but I
haven't figured out where.
Define NO_SYS_HEADERS, as the monolithic build does. Helps FreeBSD.
Don't include validate.c in the library, since it seems to be a userland
test program.
around CPU access to the framebuffer. This allows the hardware to set
up swappers to deal with endianness, or to tell EXA to move the pixmap
out to framebuffer if insufficient swappers are available (note: must
not fail on front buffer!).
