Add a structure to hold anv_states. This table will initially be used to recycle anv_states, instead of relying on a linked list implemented in GPU memory. Later it could be used so that all anv_states just point to the content of this struct, instead of making copies of anv_states everywhere. One has to call anv_state_table_add(), which returns an index for the state in the table, and then get a pointer to such index, and finally fill in the rest of the struct. TODO: 1) There's a lot of common code between this table backing store memory and the anv_block_pool buffer, due to how we grow it. I think it's possible to refactory this and reuse code on both places. 2) Add unit tests. v3: - Rename state table memfd (Jason) - Return VK_ERROR_OUT_OF_HOST_MEMORY on more places (Jason) - anv_state_table_grow returns VkResult (Jason) - Rename variables to be more informative (Jason) - Return errors on state table grow. - Rename anv_state_table_push/pop to anv_free_list_push2/pop2 This will be renamed again to remove the trailing "2" later. v4: - Remove exit(-1) from anv_state_table (Jason). - Use uint32_t "next" field in anv_free_entry (Jason).

appropriate, you should ask your question on `Freenode's #dri-devel
<irc://chat.freenode.net#dri-devel>`_, someone will redirect you if
necessary.
Remember that not everyone is in the same timezone as you, so it might
take a while before someone qualified sees your question.
