8 years agomesa/glformats: Consider DEPTH/STENCIL when resolving a mesa_format
Eduardo Lima Mitev [Wed, 3 Feb 2016 09:57:10 +0000 (10:57 +0100)]
mesa/glformats: Consider DEPTH/STENCIL when resolving a mesa_format

_mesa_format_from_format_and_type() is currently not considering DEPTH and
STENCIL formats, which are not array formats and are not handled anywhere.

This patch adds cases for common combinations of DEPTH/STENCIL format and
types.

8 years agomesa/formatquery: added FILTER pname support

mesa/formatquery: added FILTER pname support

It discards out the targets and internalformats that explicitly
mention (per-spec) that doesn't support filter types other than
NEAREST or NEAREST_MIPMAP_NEAREST. Those are:

  * Texture buffers target
  * Multisample targets
  * Any integer internalformat

For the case of multisample targets, it was used the existing method
_mesa_target_allows_setting_sampler_parameter. This would scalate
better in the future if new targets appear that doesn't allow to
set sampler parameters.

We consider RENDERBUFFER to support LINEAR filters, because although
it doesn't support this filter for sampling, you can set LINEAR
on a blit operation using glBlitFramebuffer.

mesa/formatquery: support for MAX_COMBINED_DIMENSIONS

It is implemented combining the values returned by calls to the 32-bit
query _mesa_GetInternalformati32v.

The main reason is simplicity. The other option would be C&P how we
implemented the support of GL_MAX_{WIDTH/HEIGHT/DEPTH} and GL_SAMPLES.

Additionally, doing this way, we avoid adding checks on the code, as
are done by the call to the query itself.

MAX_COMBINED_DIMENSIONS is the only pname pointed on the spec of
needing a 64-bit query. We handle that possibility by packing the
returning value on the two first 32-bit integers of params. This
would work on the 32-bit query as far as the value is not greater
that INT_MAX. On the 64-bit query wrapper we unpack those values
in order to get the final value.

When we find indirect indexing into an array, the current implementation
of the array spliiting optimization pass does not look further into the
expression tree. However, if the variable expression involves variable
indexing into other arrays, we can miss that these other arrays also have
variable indexing. If that happens, the pass will crash later on after

always indexed via constants:

shader_runner: opt_array_splitting.cpp:296:
void ir_array_splitting_visitor::split_deref(ir_dereference**): Assertion `constant' failed.

This patch fixes the problem by letting the pass step into the variable
index expression to identify these cases properly.
