Hi,
Is there a way to monitor PCI bus activity using DTrace?
I''m able to obtain the following counters through the busstat command:
dvma_stream_rd
dvma_stream_wr
dvma_const_rd
dvma_const_wr
dvma_stream_buf_mis
dvma_cycles
dvma_wd_xfr
pio_cycles
dvma_tlb_misses
interrupts
saf_inter_nack
pio_reads
pio_writes
dvma_rd_buf_timeout
dvma_rd_rtry_stc
dvma_wr_rtry_stc
dvma_rd_rtry_nonstc
dvma_wr_rtry_nonstc
E*_slow_transitions
E*_slow_cycles_per_64

Just wondering if DTrace can provide more than this.
Thanks,
