From: Marek Olšák Date: Thu, 4 Oct 2012 22:20:27 +0000 (+0200) Subject: r600g: remove the "atom" variable from r600_command_buffer X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=d8ea64697bbdbc1c7987db00a55954e4cf094ad5;p=mesa.git r600g: remove the "atom" variable from r600_command_buffer r600_command_buffer is not an atom. The "atoms" have evolved into state slots (or groups of state slots) where you can bind states. There is a fixed amount of atoms (state slots) in the context. The command buffers are nothing like that. They represent states, not state slots. We could probably give r600_atom a better name someday.
