If no TCS is provided, create a "passthrough" TCS that will take the
default values set in the API as constants and pass to the TES, along
with any other inputs it expects. The code to create the NIR shader
is the same as in i965.
Tested with
./piglit run -t 'tess' quick_shader r
and fixed a dozen crashes from that list.
not sure why this is labeled const, I'm pretty sure we are taking the
reference and owning this, so there's no particular reason we can't
change it. it certainly seems to be working for non-compute. and,
freedreno's ir3_shader.c seems to do this as well. still...gross :/
some of them had typos, didn't say 'authors or copyright holders',
or other mistakes. This is now https://opensource.org/licenses/MIT
text, formatted consistently.
looking at the freedreno code, this is totally unnecessary! we can just
store the NIR and be happy, and not have any vestiges of TGSI.
plus we can reuse this structure for compute shaders, without needing a
pipe_compute_state base.
not sure how useful this really is...
./bin/ext_transform_feedback-tessellation triangles flat_first
is hitting a case where we rebind the same VS program, but with
different streamout info...which isn't in the key...but is in the
cache...so we don't rebuild it...
This commit introduces a new Gallium driver for Intel Gen8+ GPUs,
named 'iris_dri.so' after the hardware.
Developed by:
- Kenneth Graunke (overall driver)
- Dave Airlie (shaders, conditional render, overflow query, Gen8 port)
- Chris Wilson (fencing, pinned memory, ...)
- Jordan Justen (compute shaders)
- Jason Ekstrand (image load store)
- Caio Marcelo de Oliveira Filho (tessellation control passthrough)
- Rafael Antognolli (auxiliary buffer fixes)
- The rest of the i965 contributors and the Mesa community
