I'd like to tune interrupt rate of nxge to decrease cpu usage. So, I need to know how long a NIU hardware tick is, which is used to describe rxdma-intr-time. Does anyone have information on that.
Here is the description from nxge.conf #------- Receive DMA Configuration ---------------------------- # # rxdma-intr-time # Interrupts after this number of NIU hardware ticks have # elapsed since the last packet was received. # A value of zero means no time blanking (Default = 8). # # rxdma-intr-pkts # Interrupt after this number of packets have arrived since # the last packet was serviced. A value of zero indicates # no packet blanking (Default = 20). # # Default Interrupt Blanking parameters. # # rxdma-intr-time = 8; # rxdma-intr-pkts = 20; # # #------- Classification and Load Distribution Configuration ------ thanks in advance Masa Murayama _______________________________________________ driver-discuss mailing list [email protected] http://mail.opensolaris.org/mailman/listinfo/driver-discuss
