[Lcd4linux-devel] Kernel 2.6 /proc/stat

Hi,

Recently, I've installed lcd4linux version 0.9.11 on my Gentoo Linux
system. I setup the config files and everything seems to work. However,
the Hard Disk IO stats doesn't seems to move and i checked it with
"lcd4linux -F -vvv" and it seems that the /proc/stat no longer contains
the information it needs to get the disk_io and disk_rblk.

Error: "parse(/proc/stat) failed: neither 'disk_io' nor 'disk_rblk' found"

I cat /proc/stat on a 2.4.24 kernel system and I see the lines for
disk_io and disk_rblk. However, when i do it on all 4 of my systems
running Kernel 2.6.x, none of them have it. I'm just wondering if
there's any patch for this or is there something wrong with the Kernel
2.6 or will this ever gonna work?

Best Regards,

[Lcd4linux-devel] Kernel 2.6 /proc/stat

Hi,

After looking over vmstat for a bit, it seems they've calculated the
sums of the disk stats from /proc/diskstat. Maybe it's possible to read
from that? (Just wondering if it's possible to have this work with
Kernel 2.6.x)

Best Regards,

Hmmm, this is bad news.

I will look into this as soon as my kernel 2.6 is up and running (which 
may take several weeks, because there are som mission-critical things 
not working with 2.6)

Our main kernel we're developing with is still 2.4.

Xavier, do you have time to take a look at this?

bye, Michael

Err... I may find time for this, but I don't promise you anything !
This WE I'll have to study as next week I have exams :/ But then I'm in
holidays for 2 weeks :)

BTW: this WE France will switch to 'summer time', we'll be at GMT+2, so
please set cron to send the patches at 16h from Austria :)

Bye !

Hi,

Thanx for the reply Michael. Well, while i was waiting for this reply, I
was looking at the procps's source in "vmstat.c" and "proc/sysinfo.c".
It seems there isn't any centralized value for read/write io anymore and
a sum has to be calculated from IDE devices (type 3) and SCSI devices
(type 8) in the file. I guess umm... I'll wait for some generous soul to
release a fix for this. Hehe.. and it's really nice to know someone's
looking into this matter as well. =)

Thanx lots,

~Alex
