offscreen pixmap area, and set it when any rendering occurs. When
moving a pixmap out of offscreen, don't read data back if it wasn't
dirtied (compared to the system memory copy).
out when allocation can't find a free area of the requested size. When
offscreen pixmaps get used, the offscreen area's score is increased by
a constant value. Every certain number of increases, all offscreen area
scores get decreased by a fraction. When choosing a set of areas to
remove for a new allocation, the set of areas with the smallest total
score is chosen for removal. While this is not the smartest system, it
prevents things like always removing the first offscreen area in memory
(likely the most recent) to be kicked out when doing replacing.
solid-fill-based composite acceleration.
- Use a real pixmap when doing an UploadToScratch (For pDrawable->type ==
DRAWABLE_WINDOW, you need to get the backing pixmap).
- Pass back the x/y offsets from kaaGetOffscreenPixmap unconditionally,
because they'll be used in the scratch case.
- Turn on the Render acceleration for Rage 128 and Radeon 100-series at
last!
Fix a few allocation bugs with alternate visual ids Allow for non-8/8/8
alternate visuals
Turn off any existing shadow before enabling it again (avoids
re-registering existing damage)
Add some validation code to catch re-registered damages
addition to the ARGB32 one. This allows 'glitz' to run on top of any X
server using mesa.
Switch to using 32bpp for depth 24 pixmaps (even when the frame buffer is
not depth 24).
KdCheckSync -- the boolean used in the latter won't be set yet.
Oops. == instead of =.
Must sync hardware before rasterizing trapezoids in case the mask is in
off-screen memory and has just been erased. Yes, it is silly to place
masks in off-screen memory. That's a separate issue.
Off-screen reallocation could have used a stale pointer.
Separate framebuffer mapping computation from actual frame buffer mapping.
Now map the frame buffer from vesaEnable so that VT switch shares the
same mapping code. This makes sure any shadow framebuffer is allocated
again.
pixmap into temporary offscreen storage. Subsequent UploadToScratch may
clobber the data of previous ones. This allows hardware acceleration of
composite operations on glyphs.
- Add a new UploadToScreen kaa hook for doing the actual moving of data to
framebuffer. This would allow us to do things like hostdata blits or
memcpy to agp and then blit.
- Add an UploadToScreen on ATI which is just memcpy, but which will be
replaced with a hostdata blit soon.
- Add UploadToScratch on ATI and reserve 64k of scratch space. This
provided a 3x speedup of rgb24text on my Radeon.
functions. Along with making things more readable, it fixes a problem
where the coordinates would get messed up if acceleration failed due to
things like pixmaps being in the wrong locations.
pixmaps are offscreen and don't have alpha maps. It is the last case
checked before going to software fallback
- Use the new Composite hook in the ati driver to implement acceleration of
most Composites that get done in an xcompmgr environment on r100 series
cards. It is only available when using the DRM. There are still some
corruption issues, but the DRI is still non-default and I need to get
this into version control.
- Add libdrm and libdri. Portions of the DRI extension are stubbed out.
- Use the DRM in the ATI driver when available. This provides a minor
performance improvement in x11perf, and opens the possibility of using
the 3d hardware for acceleration in the future.
- Implement solid fill acceleration for Composite in KAA.
- Implement Blend hook for Composite and use it on r128.
- Fix a bug of mine that resulted in overuse of offscreen memory.
- Fix many miscellaneous bugs in ATI driver and add PCI IDs.
available, with fbdev being used by default.
- Use depth 16 by default when vesa backend is used.
- Add MMIO defines for PowerPC (should be in a common location).
Many thanks for Michel Daenzer for much of this code.
help with ati, and future DRM drivers.
- Add new "ati" kdrive driver. It has ancestry in the r128 driver from
andersca, but took a detour through being the WIP SiS 300 driver on the
way. It supports Radeons (tested on QD VIVO and 7500) and Rage 128.
Current limitations include that it requires depth 16 and that the
other Rage 128 PCI IDs aren't included yet.
change, just cleaning up a bit)
Reset the screen->memory_base value when frame buffer is remapped. This
makes sure new off-screen allocations point at the newly mapped region
rather than the old (now unmapped) region.
Sufficient, but not always necessary.
Add borderClip to damage on creation so that clients needn't guess.
Fix API to FbDots functions to make PolyPoint work with screen_x/screen_y
offsets
Add debugging code to make sure no pictures are left pointing at freed
pixmaps. "Can't" happen, but it did once.
Change KdOffscreenArea structure to eliminate separate private structure,
eliminate the ScreenPtr, change from doubly linked to singly linked
list.
Don't damage BackgroundNone windows on PW_BACKGROUND. Re-clip damage to
borderClip in DamageSubtract.
drawable pixmap rather than directly into the frame buffer. Rewrite
logic in kdoffscreen to make space for new allocations, now deals
correctly with locked areas.
unwrapping pixmap operations. This makes sure the accelerated code gets
invoked for pixmaps
Add pixmap migration support to kaa. Can't quite automatically migrate
pixmaps off-screen, but soon we will. Can kick objects out of video
memory. Move per-screen linked list pointers to pixmap private. Wrap
Composite in preparation for migrating pixmaps. Have kasync ignore
drawable type so that pixmaps trigger sync Add KdOffscreenFini to
cleanup on server reset. Switch off screen area to have only a 'save'
function; moving objects to off screen memory is done by saving then
freeing the area.
