RE: em(4) patch for test

Can we patch it against 4.11? If not, can we patch the em_intr() to 4.11? Is this patch useful to 4.11? Thanks! David.Mao -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Gleb Smirnoff Sent: 2005年10月20日 22:02 To: [EMAIL PROTECTED] Subject: em(4) patch for

About guideline of parameters tuning while in polling mode.

Hi, everybody Can anyone give some guidelines on tuning the following parameters when the system is in polling mode and works in high throughput network environment. Thanks a lot! /* * EM_TIDV - Transmit Interrupt Delay Value * Valid Range: 0-65535 (0=off) * Defaul

polling in 4.11 vs 5.4

Hi, everybody, I hope this is the right place that I post to! When I enabled polling in 5.4 and 4.11, I found that CPU load in 5.4 is much higher than 4.11. For example, suppose HZ is 5000, in 5.4 the idle CPU is about 87%, but in 4.11, the idle CPU is about 99.9%. Is this

problems with em(4)

I have a machine running 5.4 stable, with 3 em cards: (1) Two 82543GC with fiber (2) One 82544 All of them are shared irq 11( from vmstat -i) The problem is: After the system run about 3 hours, there will be large "Ierrs" with the em0(BTW, em0 is in promisc mode). I use
