[Mesa-dev] [RFC PATCH 1/3] gallium: decrease the size of pipe_vertex_buffer - 24 -> 16 bytes

[Marek Olšák]

From: Marek Olšák <marek.olsak at amd.com>

New interface:

union pipe_buffer_binding {
   struct pipe_resource *buffer;  /**< the actual buffer */
   const void *user_buffer;  /**< pointer to a user buffer */
};

struct pipe_vertex_buffer
{
   uint16_t stride;    /**< stride to same attrib in next vertex, in bytes */
   bool is_user_buffer;
   unsigned buffer_offset;  /**< offset to start of data in buffer, in bytes */
   union pipe_buffer_binding u;
};
