Rewrite vertex and fragment programs so that we don't have to do any hacks on lower level.
|
|
|
|
|
|
Prepare for wpos and fogc handling rewrite.
|
|
|
|
Keep the original vertex program untouched because it may be needed after some state change for generating new r300 specific vertex program.

Port fixes to read buffer from front.
|
|
Need to retrieve the bits from the rrb not from screen struct
|
|
The _Enabled field isn't updated at the point that DrawBuffers is called,
and the Driver.Enable() function does the testing for stencil buffer
presence anyway.

1. new PCI ids
2. fix some 3D commands on new chipset
3. fix send instruction on new chipset
4. new VUE vertex header
5. ff_sync message (added by Zou Nan Hai <nanhai.zou@intel.com>)
6. the offset in JMPI is in unit of 64bits on new chipset
7. new cube map layout

random output is bad

It is possible to bind texture images of an incomplete mipmapped texture.
Software fallbacks in this case incorrectly tried to mmap the entire texture.
Additionally, add span functions for 1555 and 4444 formats.
This fixes crashes in piglit's fbo-readpixels test; unfortunately, the test
itself still fails - this needs to be investigated.

This updates some of the clear code from Intel gives a 5x clearspd perf
for me here. played openarena also, not sure if the viewport changes
broke anything,
|
|
it might still be misrendering not sure
|
|
fgl_glxgears -fbo runs, though the gears don't look right yet.
|
|
otherwise we decrement indexes for all registers
|
|
|

Same story as in the tgsi_dump.c code (see prev commit).
|
|
Fixes TGSI dump output when front/back-face register is declared.
Also, add some assertions to make sure the semantic/interpolate string
arrays have as many elements as there are tokens in the p_shader_tokens.h
file. That should catch problems like this in the future.
|
|
|
|
Includes the TGSI interpreter, but not the SSE/PPC/etc code generators.

make sure to turn off when no texture is used in hw

The values 2147483648.0 and 4294967294.0 are too larget to be stored in single
precision floats. Forcing these to be singles causes bits to be lost, which
results in errors in some pixel transfer tests.
This fixes bug #22344.

When a function parameter is const-qualified we can avoid making a copy
of the actual parameter (we basically do a search/replace when inlining).
This is now done for array element params too, resulting in better code
(fewer MOV instructions).
We should allow some other types of function arguments here but let's be
conservative for the moment.

The two indexes were mixed up when accessing a row of a matrix in an array
of matrices.

two)
The semantics are a little different for shaders vs. fixed-function when
trying to use an incomplete texture. The fallback texture returning
(0,0,0,1) should only be used with shaders. For fixed function, the texture
unit is truly disabled/ignored.
Fixes glean fbo test regression.

[anholt: squashed these two together from master, skipping the mess in between]

Also fix one case where a 32 bit depth value was incorrectly converted to a
combined depth/stencil value.
|
|
Such visuals are subject to automatic compositing in the X server, so DRI1
can't render to them properly.
|
|
Fixes potential crash when SwapBuffers is called but there's no back buffer.
|
|
fix the cases when fog coord/front face/point coord are used in the same
shader.
|
|
Ensure no other thread is accessing a framebuffer when it is being destroyed by
acquiring both the global and per-framebuffer mutexes. Normal access only
needs the global lock to walk the linked list and acquire the per-framebuffer
mutex.
|
|
Fixes wglthreads -- the 2nd thread MakeCurrent call was trying to flush
the first thread context while still in use.

According to
http://blogs.msdn.com/oldnewthing/archive/2008/01/15/7113860.aspx
WM_SIZE is generated from WM_WINDOWPOSCHANGED by DefWindowProc so it
can be masked out by the application.
Also there were some weird bogus WM_SIZE 0x0 messages when starting
sharedtex_mt which we don't get like this.
