If nvfx_framebuffer prepare and validate were called successively with
fb->zsbuf not NULL and then NULL, nvfx->hw_zeta would contain garbage and
this would cause failures in nvfx_framebuffer_relocate/OUT_RELOC(hw_zeta).
This was triggered by piglit/texwrap 2D GL_DEPTH_COMPONENT24 and caused
first a 'write to user buffer!!' error in libdrm and then worse things.

Add explicit EVENT_TYPE field
|

This fixes piglit/glsl-vs-main-return and glsl-fs-main-return for the drivers
which don't support RET (i915g, r300g, r600g, svga).
ir_to_mesa does not currently generate subroutines, but it's a matter of time
till it's added. It would then break all the drivers which don't implement
them, so this CAP makes sense.

It looks like this was meant to facilitate unfenced access to textures/
color/renderbuffers. It's totally incomplete and fundamentally broken
on a few levels:
- broken: The kernel needs to about every tiled bo to fix up bit17
swizzling on swap-in.
- unflexible: fenced/unfenced relocs from execbuffer2 do the same, much
simpler.
- unneeded: with relaxed fencing tiled gem bos are as memory-efficient
as this trick.
Hence kill it.

Somebody should find out what these are. It can be found on Windows
getting a D3DCAPS9 from IDirect3D9::GetCaps() and reading the
GuardBand* values.

We do not know how to use more, GL_ARB_draw_buffers is not exposed on blob.

The stride between the different clip plane registers was incorrect.

Fixes glsl-vs-point-size, although I meant to fix glsl-novertexdata.
Since swrast fails glsl-novertexdata too, I guess it's a core issue.

Use fetch shader instead of having fetch instruction in the vertex
shader. Allow to restrict shader update to a smaller part when
vertex buffer input layout changes.

Vertex data swizzles are already done in the vertex shader. Doing them twice
breaks BGRA vertex arrays for example.
|
|
RET was interpreted as END, which was wrong. Instead, if a shader contains RET
in the main function, it will fail to compile with an error message
from now on.
The hack is from early days.

The (piglit) mipmap_limits test shows the issue very clearly.

This driver is a fake swdri driver that perform no operations
beside allocation gallium structure and buffer for upper layer
usage.
It's purpose is to help profiling core mesa/gallium without
having pipe driver overhead hidding hot spot of core code.
scons file are likely inadequate i am unfamiliar with this
build system.
To use it simply rename is to swrast_dri.so and properly set
LIBGL_DRIVERS_PATH env variable.

Currently r600_resource_copy_region() will turn these copies into
transfers + memcpys, so to avoid recursion we must not turn those
transfers back into blits.
