# Apply to all devices:
|
||
|
|
# PCIPARM_ALL="...."
|
||
|
|
# Cards also can be addressed by vid:pid or by bus:slot.func
|
||
|
|
# (see setpci man page relative to -d and -s options)
|
||
|
|
# PCIPARM_(BUS|VENDOR)_#="...."
|
||
|
|
# Where # is sequentially numbered from zero.
|
||
|
|
|
||
|
|
# Examples:
|
||
|
|
# "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/under-run conditions
|
||
|
|
#PCIPARM_BUS_0="00:04.0 latency_timer=ff"

#PCIPARM_BUS_1="01:04.0 latency_timer=ff"
