intel: Fix intel_map_renderbuffer() for depthstencil buffers with separate stencil

For a depthstencil buffer with separate stencil,
intel_renderbuffer::region is null. (The regions are kept in hidden depth

was dereferenced (!) by MapRenderbuffer's caller.

This patch fixes intel_map_renderbuffer() to map the hidden depth buffer
through the GTT and return that as the mapped pointer. Also, the stencil

        int i = abs(5);

The second call, abs(5), would find the newly imported float signature

2. Generate the actual ir_call (assuming we found the callee).

Both of these are complicated.  The first has to handle exact/inexact

The second has to deal with void/non-void functions, pre-call implicit
conversions for "in" parmeters, and post-call "out" call conversions.

Trying to do both in one function is just too unwieldy.  Time to split.

whether or not it was exact.  (If not, we may want to keep looking.)

This could be done via the existing mechanisms:

      exact = true;

However, this requires walking the list of function signatures twice,
which also means walking each signature's formal parameter lists twice.
This could be rather expensive.

Since matching_signature already internally knows whether a match was
exact or not, we can just return it to get that information for free.

This is a band-aid for these two problems:
- The R600 and EG control-flow instructions appear in switch statements
  next to each other, causing conflicts when adding new instructions.
- The ALU control-flow instructions are bitshifted by 3 (from CF_INST 26:29
  to CF_INST 23:29, as is defined by r600 ISA) even for EG, where CF_INST
  is 22:29.

To fix this mess, the 'inst' field is bitshifted to the left either by 22, 23,
or 26 (directly in the definitions), such that it can be just or'd when making
bytecode without any shifting. All switch statements have been divided into
two, one for R600 and the other for EG.

Of course, there is a better way to do this, but that is left for future
work.

Tested on RV730 and REDWOOD with no regressions.

i965: Remove nr_surfaces computation from brw_update_wm_surfaces.

This code is fairly fragile, as it depends on the ordering of the

Also, stop listening on the BRW_NEW_WM_CONSTBUF dirty bit as it's no
longer required.

12 years agoi965: Use 0 for the number of binding table entries in 3DSTATE_(VS|WM).

i965: Use 0 for the number of binding table entries in 3DSTATE_(VS|WM).

These fields control how many entries the hardware prefetches into the
state cache, so they only impact performance, not correctness.  However,
it's not clear how to use this in a way that's beneficial.

According to the documentation, kernels "using a large number" of
entries may wish to program this to zero to avoid thrashing the cache;
it's unclear how many is too many.  Also, Ironlake's WM was missing this
feature entirely---the count had to be zero.

The dirty bit tracking to handle this complicates the surface state
and binding table setup; removing it should simplify things and make
future refactoring easier.  So just set 0 for the number of entries
rather than trying to compute and track it.

Appears to have no impact on Nexuiz and OpenArena on Sandybridge.

usage is the same, and callers just want to utilize the appropriate
functions with minimal pain.  So, put them in the vtable.

Since these take a brw_context pointer and are only used on Gen4, just
add a forward declaration.  This is the simplest (if not cleanest)
