This reverts commit c50ffc4cb89b67ae59208eb72cdb664c846ba987.
I'll fix this using the mipmap hooks I just picked from gallium-0.1

This at least stops the compiz brain explosion we were seeing, I do wonder
though if we should somehow be calling intel_generate_mipmap somehow.

Mostly some pedantic changes such that `make clean' always ignores
errors. Also changed the top clean target to do the `touch
configs/current' dance instead of realclean.
|
|
Consistently cleanup the depend.bak files created by makedepend. Also,
realclean has been changed to use a single find command, which speeds it
up considerably.
|
|
When changing directories and running a sub-make, ensure that both the
cd and make commands propagate errors to the parent make.

Negative value means other errors, not aperture overflow. fix bug #15752

We really need to update the shader state so the texrect parameters work.
This should fix compiz looking crappy on rs480 and rs690

The previous default these days served mostly to cause artifical problems with
GLX compositing managers like compiz (see e.g.
http://bugs.freedesktop.org/show_bug.cgi?id=10501).

The 32-bit immediate value in the i965 instruction word must contain two
copies of any 16-bit constants. brw_imm_uw and brw_imm_w just needed to
copy the value into both halves of the immediate value instruction field.

If vs output is big, driver may fall back to use 8 urb entries for vs,
unfortunally, for some unknown reason, if vs is working at 4x2 mode,
8 entries is not enough, may lead to gpu hang.

Makes state emission into a 2 phase, prepare sets things up and accounts
the size of all referenced buffer objects. The emit stage then actually
does the batchbuffer touching for emitting the objects.
There is an assert in dri_emit_reloc if a reloc occurs for a buffer
that hasn't been accounted yet.

batchbuffer > aperture size.
So with compiz on Intel hw with fake bufmgr, opening 4 firefox windows at 1680x1050 and hitting alt-tab, could cause the batchbuffer to try and reference more than the 32MB of RAM allocated.
Fix 1:
Fix 1 is to pre-verify the list of buffers against the current batchbuffer and if it can't possibly fit in the aperture to flush the batchbuffer to the hardware
and try again. If the buffers still can't fit well then you are hosed as I'm not sure there is a nice way to tell anyone.
Fix 2:
Next problem was that even with a simple check for total < aperture, we ran
into fragmentation issues, this meant that half way down a set of buffers,
we would fail as no blocks were available. Fix this by nuking the memory
manager from orbit and letting it start again and relayout the blocks in a
manner that fits.
Fix 3:
Finally the initial problem we were seeing was a memcpy to a NULL backing store.
We seem to end up with a texture at some point that never gets mapped but ends up with data in it. compiz al-tab icons have this property. So I created a card dirty bit that memcpy's any buffer that is !static and is written to back to memory. This probably is wrong but it makes compiz work for now.
Caveats:
965 support is still fail.

due to the two read ports limit into temp memory may need the MAD_2 instruction
for the second instruction of the decomposed XPD.
While here, also try to avoid MAD_2 for MAD if all 3 inputs are temps but the
temps aren't actually distinct.
