"unsafe" is never initialized, but used
(found by valgrind)

nv50_pre_pipebuffer_map references screen->cur_ctx which points
to freed memory after the context is destroyed.
This crash is easily triggerable by progs/xdemos/glxcontexts.

Still not handling queries on multiple contexts though.
|

This function was untested, sorry.
|
|
And fix some obvious mistakes introduced in the
previous instancing commit.

Fixes lockup triggered by this ingenious shader:
1: CALL :3
2: END
3: BGNSUB ...

Too bad we don't have hw array divisors or a method for
setting startInstance.

Vertex data in geometry programs is located in p[] space.
The base address in p[] for vertex i is located in vertex
attribute space, i.e. a[i << 2].
This means p[] is always accessed with an address register,
and I had to to mess with their allocation once again.
Also fixes negative offsets e.g. CONST[ADDR[0].x - 3].

Otherwise we risk overwriting them with temporary GPRs if
they're not used immediately after the CALL.

NOUVEAU_BO_RD is defined (1 << 2), and `|' has higher precedence than `?'
so the second argument of nouveau_bo_map was always 0.

This patch removes PIPE_TEX_FILTER_ANISO.
Anisotropic filtering is enabled if and only if max_anisotropy > 1.0.
Values between 0.0 and 1.0, inclusive, of max_anisotropy are to be
considered equivalent, and meaning to turn off anisotropic filtering.
This approach has the small drawback of eliminating the possibility of
enabling anisotropic filter on either minification or magnification
separately, which Radeon hardware seems to support, is currently
support by Gallium but not exposed to OpenGL. If this is actually
useful it could be handled by splitting max_anisotropy in two values
and adding an appropriate OpenGL extension.
NOTE: some fiddling & reformatting by keithw to get this patch to
apply. Hopefully nothing broken in the process.

- The previous solution was hacky and didn't do subchannel autobinding.
- The beheaviour should match what libdrm_nouveau does closely.
- The solution remains statically sized, but when debugging is on it will check
for abuse.

- This avoids problematic "reloc'ed while mapped" messages and
some associated corruption as well.

The immediate's bits eat the condition bits.
|
|
Cannot change hw reg assigned to a TGSI TEMP on the fly if
we are in a loop, conditional, or can jump around wildly.
|
|
Not that they make much sense on nv50, but we also do LIT ...
|
|
|
|
If we create multiple instances of an nv50_reg referencing
them same resource, register allocation from alloc_reg has
to be done with the original nv50_reg.
|

|
|
Also fixes RSQ of negative sources.

This negation would only be triggered in situations
where it's incorrect.
The caller of set_immd should negate the immediate value
in the instruction itself if desired, and will also know
if it's a float or an int.
ADD TEMP[0], CONST[0], -IMMD[0] would load the immediate
into extra TEMP, negated, and set the negate flag in add
as well - double negation.

- unreference state objects so that buffer objects are unreferenced and
eventually destroyed
- free channel at screen's destruction
Based on Krzysztof Smiechowicz's patch.

It doesn't seem to be possible to set the egdeflag in the
vertex shader, so we need to fallback to pushing vertices
through the FIFO and use method 0x15e4 if they are used.
This only works if VP does MOV OUT[X] IN[Y] where X is the
edgeflag output, and Y is saved so we can tell the correct
input later.
The VP still writes the useless values to wasted outputs
as punishment.
