This article is so out of date it's of no real use any more, and
updating it seems quite pointless. Let's just move it to the graveyard,
and forward any readers to the version we have in the amber-release.

This isn't content that relates directly to a specific release of Mesa,
and it's also quite out-of-date. Let's move it to the main mesa website
instead, where we have an updated version.

These were meant to explain the LDS layout, but
the actual LDS usage is better explained by:

Most tools looking at shader stats assume that there is only a single
resulting binary shader out of a single input. On Intel HW this is not
always the case. So having a statistic on each variant that reports
the maximum dispatch width helps showing improvement on a single
shader in terms of how large we manage to compile it.
For shaders that can be compiled in multiple SIMD width (like fragment
shaders), this will report the maximum dispatch width in the
statistics of each variants.

When cs allocation fails in radv_create_cmd_buffer,
radv_destroy_cmd_buffer is called before returning
VK_ERROR_OUT_OF_HOST_MEMORY. At that point, the upload list is not
initalized yet, so SIGSEGV will occur when trying to iterate through the
upload bo list. Initialize the upload list earlier to avoid this.

this improves handling for barriers that originate from a write in the
unordered cmdbuf, adding tracking to resources to better determine access
in the unordered cmdbuf and then utilizing that to generate a single split
memory barrier added at the end of the unordered cmdbuf for all the buffers
written to on that cmdbuf
the next step will be to also merge the read access down onto the end-of-cmdbuf
barrier so that all stream upload-type functionality becomes a single barrier

previously the unordered access flags would be set before the deferred
