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 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
