devPrivate.ptr when pointing at offscreen memory, outside of
exaPrepare/FinishAccess(). This was used with fakexa to find (by NULL
dereference) many instances of un-Prepared CPU access to the
framebuffer:
- GC tiles used in several ops when fillStyle == FillTiled were never
Prepared.
- Migration could lead to un-Prepared access to mask data in render's
Trapezoids and Triangles
- PutImage's UploadToScreen failure fallback failed to Prepare.
Add the server side implementation of the ScreenSaverSuspend request.
Require scrnsaverproto >= 1.1, and change the linking order of the Xorg
static libs.
plug in the accelerated one, even if the destination pixmap is
currently offscreen. This was a leftover from when kaa originally got
accelerated offscreen pixmap support, and its only concievable use was
to avoid a little overhead on ops to in-system pixmaps that weren't
going to get migrated. At this point, we probably care more about just
getting everything accelerated that we easily can, which should happen
with the new migration support.
Fixes for some vsw4 failures on 64bit BE platforms such as PPC64 and s390x.

FB_ALLONES, bitsPerPixel >= 8, GXcopy cases. With the radeon driver on
my machine, this gives about 10% speedup in PutImage
10x10 and 500x500, and 40% speedup for 10x10 ShmPutImage, up to 65%
improvement in 500x500 ShmPutImage. Also fixes a crasher in GetImage
that slipped in at the last minute.
ZPixmap, planeMask ~= FB_ALLONES, bitsPerPixel >= 8 case. I'm pretty
convinced that this is the only case that we care about at all. Tested
with xwd -root and xwd on a gnome-terminal, in a composited environment
or not.
acceleration, and set the migration scheme to Always on init (since
this is all for testing, and Always should make migration happen more
frequently than Greedy).
Add GL_ARB_texture_non_power_of_two, GL_EXT_framebuffer_object and
GL_NV_texture_env_combine4 extensions.
Add __GLXcontext destructor and flush context cache there and on
loseCurrent.
Chain back to new __GLXcontext destructor. (__glXMesaContextForceCurrent):
Set render table on forceCurrent. (init_screen_visuals): Index pVis
array correctly. (GlxGetMesaProvider): Add this.
Hook up FBO marshalling.
pixmap, and damage is tracked so that a later exaMoveInPixmap won't
result in an upload if no upload is necessary. This will likely improve
the performance of the "Always" migration scheme significantly, and is
a step in the path to more exact damage tracking between framebuffer
and system memory.

initialized for the current server generation. Fixes a problem where it
would use stale private index and blow up in colorful ways if no driver
called DRIScreenInit() on the second generation (which happens due to a
bug in radeon that i'll fix separately). Note: clearing the index in
DRIReset() wouldn't work as DRIReset() is called before the

desired location always (unless they don't fit in FB, in which case
they all get moved out for software rendering). The default remains as
before, but can be controlled by the MigrationHeuristic xorg.conf
option (which is intentionally not documented, as it may be
short-lived). This is part of the exa-damagetrack work, which appears
stable in testing with fakexa, unlike the work as a whole.
manual conversion to allow for different migration schemes to be
implemented reasonably, but does include some minor improvements such
as accounting for pinned pixmaps not being acceleratable, and for our
current GetImage and GetSpans not being accelerated.
Add getter for Mesa provider.
Export this for Xgl.
Move resource tracking out of drawable constructor to allow wrapping.
Use corrent reply size #define.
Add this function. (DoGetDrawableAttributes): Fix array length.
same width/height for front-buffer drawing. The fakexa code then uses
this extra space for offscreen pixmaps. Note that this tones down the
absurdity of fakexa's offscreen pixmap alignment requirements (odd
alignment is too weird, so stick with "24", which is still strange but
exists out there). It also fixes a couple of bugs in the fakexa
implementation revealed by using offscreen pixmaps.
This patch is from DragonFly developer Joerg Sonnenberger and the pkgsrc
collection.
I tested using /dev/sysmouse with moused using my serial /dev/cuaa0.
corresponding pieces of exa-driver.txt, which were becoming stale.
Hopefully the documentation will stay much more up-to-date this way.
Many thanks to jbarnes for writing exa-driver.txt which was used a lot
in writing this documentation.
when extending the driver interface. The card and accel structures are
merged into the ExaDriverRec, which is to be allocated using
exaDriverAlloc(). The driver structure also grows exa_major and
exa_minor, which drivers fill in and have checked by EXA
(double-checking that the driver really did check that the EXA version
was correct). Removes exaInitCard(), which is replaced by the driver
filling in the rec by hand, and the exaGetVersion() and related
EXA_*VERSION which are replaced by always using the XFree86 loadable
module versioning.
PICT_a8r8g8b8. Fixes a failure in the gradients test of rendercheck. In
the long term we could do better by setting the format to something
without alpha whenever the gradient doesn't contain colors with alpha.
This triggers a reduction of the over operation to a pure source
operation.
implementation that calls fb to get its work done. The purpose is to
have a trusted EXA driver for use with testing changes to the core of
EXA. However, fakexa has not received much testing yet, lacks offscreen
pixmaps support, and doesn't reliably provide garbage when EXA doesn't
get its syncing right. All of these should be fixed soon.
function pointers to implement a level of flexability that was never
used. The code also had unused support for extracting a single image
type from a larger expansion ROM.
Fix the spelling of PCI_BIOS_OPEN_FIRMWARE.
Fix a couple errors in #ifdef debug code.
These changes have been tested on x86 and x86-64 Linux.
Class information is not, and never has been, stored there. Therefore,
this is just a bunch of elaborate code to read 0x00000000.
This has received testing on x86 and x86-64 Linux.
the current cursor when disabling FB access and would try to restore
that cursor when re-enabling. However, that cursor might have been
destroyed in between. This fixes it by updating the saved cursor
pointer when a cursor is set and vtSema is FALSE.
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.
