hi all,
I have been looking into the Tigon firmware code and i am totalyy
puzzled about this: there is no place in the code where
trp->local_mem_conf.rx_buf_consumer is incremented. (except in
h_mac_rx_comp_nohost() which is not called) The tigon documentation says
that it should be incremented by the firmware after the frames have been
dma'd into the host. But h_dma_wr_assist() never does that. Setting a
watchpoint on this register i saw that the register changes when the
"dma write assist producer" register is updated in q_dma_to_host(). Isnt
this strange??.....or am i missing something?? can anybody explain??
thanx in advance
joy
