[Mesa-dev] [PATCH 02/10] r600g: Add pkt_flag member to struct r600_command_buffer

[Tom Stellard]

Some packets require the shader type bit (bit 1) to be set when
used for compute shaders.  The pkt_flag will be initialized to
RADEON_CP_PACKET3_COMPUTE_MODE for any struct r600_command_buffer used
for dispatching compute shaders and it will be or'd against the result of
the PKT3 macro when adding a new packet to a strcut r600_command buffer.
