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.
