Do proper reference counting so that we don't wind up with dangling
references to deleted windows/framebuffers. Should help with bug 7205.

In i915_miptree_layout() change the width, height parameters that are passed
to intel_miptree_set_level_info(). As it was, the width, height values were
larger than the source image dimensions and we segfaulted in memcpy() when
copying the original texture data into the texture buffer region.
This fix should probably be checked by someone more familiar with the code (Keith?)

Mostly:
- update #includes
- update STATE_* token code
|
|
|
|
|
|
|
|
Also move vsync related state from context to window, so it's possible to
schedule several flips ahead of time with triple buffering.

Pending flips are tracked per renderbuffer and the colour renderbuffer
attachments of window framebuffer objects are rotated on flips to avoid
stalling the pipeline for pending flips unnecessarily.

intel_get_rb_region already takes the current page into account.
This would result in broken rendering when multiple 3D windows are visible
and the pages are reversed.
|
|
No longer track page flipping state per context but per window, via struct
intel_framebuffer which wraps struct gl_framebuffer for windows.

With current memory preferences, vbos ended up in AGP space
where reading from them got a bit slow.
Make sure buffer objects are initially created in system memory.

Updated all drivers that used the old _ac_ functions to use
the new _vbo_ functions. I know this fixed the fbdev driver,
it looks like it might fix some other drivers too.

So this do :
- Fixes COS.
- Does range reductions for SIN & COS.
- Adds SCS.
- removes the optimized version of SIN & COS.
- tweaked weight (should help on precision).
- fixed a copy paste typo in emit_arith().
|
|
|
|
batch buffer after a resolution / rotation switch.
|
|
Wait until getting the right fence if drm/i915 resets the
counter.
|
|
Getting proper SIN and COS wasn't as easy as it appeared.
I had to make make some changes to the fragment program code.
general FP changes:
- support HHH swizzle for vector instructions.
- don't copy a source to a temp when it is not XYZW swizzled, but
combine the two and have the swizzle resolve any issues.
(saves temps/instructions with more elaborate shader code)
- fix overflow in cnstv[].
|
|
Use the same input map handling for fftnl and vertex programs. It doesn't
enable any new functionality (should make it easy to support per-vertex
materials though), but the code is much cleaner.
|
|
Redirect all VERT_RESULT_HPOS writes to a temp and use that for fixup.
The viewport transformation still seems to take some shortcuts, and it
still does not seem to work at all...

This fixes the *actual* bug that the previous commit was supposed to fix..
|
|
|
|
The old code suffered from a number of issues, the most severe being that
with the Mesa VBO merge even swtcl used the driver's bufferobj interface.
On most VBO types (or non-AGP cards) the buffer ended up in vram, and
killed swtcl performance greatly. All bufferobj's start in system memory
now, until they get referenced as a "real" VBO.
The other big change is that only potentially "damaged" areas are
uploaded/downloaded to/from the hardware.
