# PCI tweaking article:

# http://www.gentoo.org/doc/en/articles/hardware-stability-p2.xml
|
|
#
|
|
# 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"
|
|
#PCIPARM_VENDOR_0="1057:3410 latency_timer=ff"
|
|
|
|
# -v : whether to be verbose about changes
|
|
# -D : dry-run, no commit
|
|
# -f : do not warn if the change is already set
|
|
# (see the setpci manpage for more advanced options)
