      vulkan: change infinite loop polls to block indefinitely · 644f9d57
      Niklas Haas authored
      I forgot what the original justification was for using short timeouts
      here (perhaps some driver bug?) but in any case, it doesn't seem to make
      any sense anymore.
      This reduces CPU usage drastically on some drivers. I kept one loop at
      10 ms since it shouldn't be hit anyways, and this way we know it's stuck
      in that loop for absurd amounts of time.

      xtalloc: Re-prefix all ta_* symbols to xta_* · 12aab84a
      Philip Langdale authored
      xtalloc was copied from mpv, which means that we see symbol
      collisions if libplacebo is statically linked into mpv. So
      use an `xta_` prefix for all the functions. In practice, this
      has almost no effect on the consuming code because everything
      is accessed via macros.

      spirv: Prefix spirv compiler function struct names · 4912e344
      Philip Langdale authored
      These structs are included via extern declarations, so they can
      silently conflict with equivalently named declarations in an
      application if libplacebo is included statically.
      And this happens with mpv, which also declares a `spirv_shaderc`
      So, prefix the struct names with `pl_` to avoid this.

      vulkan: fix overzealous misalignment check on texture transfers · e16dd395
      Niklas Haas authored
      These made it so that the async transfer queue was never actually used.
      This is obviously a massive performance regression on all drivers
      supporting asynchronous transfer (e.g. AMDVLK).
      The spec explicitly allows the case where the transfer spans the entire
      image, i.e. offset+extent = size.

      shaders/av1: release under MIT · 2ee4b041
      Niklas Haas authored
      dav1d people want this to be permissive so they can adapt it for
      documentation purposes. I have no problems releasing this specific file
      under a permissive license.
      Note that since both the header and source code heavily depend on the
      LGPLv2.1+ parts of libplacebo, this licensing change isn't terribly
      useful unless you're just interested in copying fragments of the glsl
      code or some of the C helper functions.

      shaders: compat for GLSL < 130 · bd502804
      Niklas Haas authored
      We need to use the explicitly named functions like texture2D(),
      texture3D() etc. for low GLSL versions. Add a bunch of shitty
      compatibility code to template out the function name.
      The specific way I solved it also opens us up to allowing e.g. rectangle
      textures in the future.

      shaders: allow overriding shader GLSL version explicitly · 27835a8b
      Niklas Haas authored
      This can be useful for API users that don't want to go through the
      bother of setting up a dummy `pl_gpu` just to create some shaders.

      shaders: refactor shader creation API · 729e4aee
      Niklas Haas authored
      - I wanted to add new parameters, and rather than having the function
        signature grow out of control, I decided to switch to the same
        `params`-style as the rest of libplacebo, for future forwards
      - We need to expose the identifier, because users of raw shaders might
        want to combine multiple shaders into the same GLSL program.
      This kills off the hacky `_ex` functions and uses a params struct. Also
      organizes some fields around, for reasons.

      shaders: change implicit GLSL version assumptions · 44b4f779
      Niklas Haas authored
      Instead of assuming the lowest possible, assume GLSL 130 as the
      baseline. This requires bumping the API version because it is a breaking
      change to some use cases.
      Also a missing GLSL version compat check to the dither code.

      swapchain: add resizing API · ad242535
      Niklas Haas authored
      This is used both for updating the size and querying the size. I don't
      want to make these separate functions because it should be painfully
      obvious that the size you get may not be the size you request.
      This allows libplacebo to work on wayland, which mediates the concept of
      swapchain resizing to protocols like xdg_shell that mesa/vulkan can't
      know anything about (by design).

      gpu: actually generalize `pl_tex_export` · 3294a29e
      Niklas Haas authored
      We accidentally implemented this inside vulkan/gpu.c instead of the
      general purpose wrapper code. That also meant we never tested the
      `tex->params.export_handle` condition.
      However, I realized that this condition is actually too restrictive for
      our test framework, and working around it there would be sort of
      annoying. So just drop the restriction.
      I won't bother updating the API version for this change, since the
      actual behavior hasn't changed. (And even if it had, it would only
      matter for our own test framework)
      As an aside, fix a bunch of related comments that still had outdated
      field names in the documentation.

      vulkan: implement proper buffer queue tracking · 70946fc9
      Niklas Haas authored
      Turns out that this actually causes problems when e.g. trying to reuse
      an SSBO between a compute shader and a fragment shader, which comes up
      when using the new peak detection code.
      One annoying thing about the implementation is that we will always need
      to make sure that buf_flush happens after buf_signal, since the former
      depends on the stage variable set by the latter. Maybe I'll change this
      in the future if it gets annoying.
      Fixes #49.
