interrupt storm - delsi mail

[Petr Macek]

Nedalo mi to a jeste jsem si s tim chvilku hral. Sitovky xl podporuji 
polling. Zkompiloval jsem kernel s:
options DEVICE_POLLING
options HZ=1000

a jeste pridal radek do /etc/sysctl.conf.

Takze ted to vypada takhle:
sysctl -a | grep polling
kern.polling.burst: 5
kern.polling.each_burst: 5
kern.polling.burst_max: 150
kern.polling.idle_poll: 0
kern.polling.poll_in_trap: 0
kern.polling.user_frac: 50
kern.polling.reg_frac: 20
kern.polling.short_ticks: 0
kern.polling.lost_polls: 0
kern.polling.pending_polls: 0
kern.polling.residual_burst: 0
kern.polling.handlers: 0
kern.polling.enable: 1
kern.polling.phase: 0
kern.polling.suspect: 0
kern.polling.stalled: 0
kern.polling.idlepoll_sleeping: 1

ale zadnou zmenu nepozoruji. Kdyz se mi tam objevi nejaky sit. provoz, 
zase mi system zobrazi hlasku interrupt storm. Proti predchozimu stavu 
(bez pollingu) nepozoruju zadnou zmenu.

Zapomnel jsem na neco?

Diky za rady
