Texel buffers are currently described by a TextureDescriptor,which leads to restrictive limits on size and alignment. These limits can be avoided by using a BufferDescriptor instead. This requires first embedding a ConversionDescriptor into some of the currently empty space of the BufferDescriptor, and modifying the compiler so that instead of outputting TEX_FETCH, it will: 1. Load the ConversionDescriptor with LD_PKA 2. Get the buffer address with LEA_BUF[_IMM] 3. Use LD_CVT to get the value Reviewed-by: Erik Faye-Lund <erik.faye-lund@collabora.com> Reviewed-by: Boris Brezillon <boris.brezillon@collabora.com> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/37007>
