These do similar jobs but with largely disjoint code. Will want
to evolve them separately going forward.
|
|
This reverts commit 1295cf423e21dad04a947960782ffa8db2739709.
The original formulation was easier to understand & work with. Will
revisit this later.
|
|
Unshare one function (setup_pos_vector) as we want to push this code
into the generated shader in the SSE case.
|
|
However we do llvm integration, it will be different & more comprehensive
than this.

Stray '- 0.5' copied from linear versions.
|
|
All these fastpaths are examples of the types of things we'd code-generate
in a more sophisticated version of softpipe.
|
|
Because this is interpolated (ie. early) depth, we can build in an
assumption about the quads emitted by triangle setup, ie that they
are actually linear spans. Interpolate z over those spans in z16
format to save on math & conversion.

Disable blend code when no color buffer
|
|
|
|
|
|
|
|
Consolidate the read-modify-write color combining code from
the blend, colormask and output stages.
|
|
|
|
|
|
First attempt
|
|
This is part one -- we still only pass a single quad down, but
the code can now cope with more. The quads must all be from the same
tile.

There's no need to push out depth buffer contents on swapbuffers.
Note that this change doesn't throw away depth buffer changes, it simply
holds them in the cache over calls to swapbuffers. The hope is
that swapbuffers will be followed by a clear() which means in that case
we won't have to write the changes out.
|
|
|
|
The sp_tile_cache is often called repeatedly to look up the same
tile. Add a cache (to the cache) of the single tile most recently
retreived and make a quick inline check to see if this matches the
subsequent request.
Add a tile_address bitfield struct to make this check easier.

No loss of performance, but simpler code.
|
|
No performance gain yet, but the code is a bit cleaner.
|
|
Makes some difference, but suprisingly little. Barely worth the effort.
|
|
The leading underscore is meaningful... This function is used by
_warning and _error functions as well as the more common
debug_printf().
debug_printf (without underscore) gets turned off when DEBUG is
disabled, but warning/error messages still use this function to get
their message out.
|
|
The tile cache is a utility, it shouldn't know anything about the
entity which is making use of it (ie softpipe).
Remove softpipe parameter to all the tilecache function calls, and
also remove the need to keep a softpipe pointer in the sampler structs.

This is a source of ongoing confusion. TGSI has multiple names for
opcodes where the same semantics originate in multiple shader APIs.
For instance, TGSI includes both Mesa/GLSL and DX/SM30 names for
opcodes with the same semantics, but aliases those names to the same
underlying opcode number.
This makes it very difficult to visually inspect two sets of opcodes
(eg in state tracker & driver) and check if they implement the same
functionality.
This patch arbitarily rips out the versions of the opcodes not currently
favoured by the mesa state tracker and leaves us with a single name
for each distinct operation.
|

Remove the need to have a pointer in this struct by just including
the immediate data inline. Having a pointer in the struct introduces
complications like needing to alloc/free the data pointed to, uncertainty
about who owns the data, etc. There doesn't seem to be a need for it,
and it is unlikely to make much difference plus or minus to performance.
Added some asserts as we now will trip up on immediates with more
than four elements. There were actually already quite a few such asserts,
but the >4 case could be used in the future to specify indexable immediate
ranges, such as lookup tables.

This function was calling get_input_base() and get_output_base() to
get the names of a couple of register to use as temps. Those
functions no longer return registers, so adjust it to get the
registers elsewhere.
This change doesn't address the issue that it's a fairly poor way to
grab a register name by calling a function with an apparently
unrelated meaning.

Flagged by the DRM command stream checker. This allows the driver to work on
non-R500 cards.

A context or surface that is neither linked to a display nor current to
a thread should be destroyed. Therefore, an unlinked context or surface
implies a pending delete automatically.

This commit uses the newly introduced link functions to manage EGL
contexts and surfaces. As a result of this, the API for drivers are
changed. All drivers are updated for the change.

Use sse_movmskps to extract the correct bits of the comparison result
for use in updating the killmask. Simplify some logic around
identifying the set of necessary comparisons to make.
