# "open up" the PCI bus by allowing fairly long bursts
# for all devices, increasing performance
# (equivalent to: setpci -v -d *:* latency_timer=b0)

PCIPARM_ALL="latency_timer=b0"

# maximize latency timers for network and audio,
# allowing them to transmit more data per burst,
# preventing buffer over/underrun conditions

# cards can be addressed by vid:pid or by bus:slot.func
# (see setpci man page relative to -d and -s options)

PCIPARM_BUS_0="00:04.0 latency_timer=ff"
PCIPARM_BUS_1="01:04.0 latency_timer=ff"
PCIPARM_VENDOR_0="1057:3410 latency_timer=ff"

# wether to be verbose about changes
