adb - tunable global variable

Volker Kiehn — Thu, 21 Nov 2002 12:04:13 GMT

I'm interested in debugging the kernel. I know about global variable like vhandinfoticks (vhand prints informations to syslog). They have to been set by adb.

What is the syntax to do this?

echo "vhandinfoticks/W 500" | adb -w -k /stand/vmunix /dev/mem

maybe ? where 500 =<#sec> ... I could be wrong ........

that works fine

But the value 500 isn't the number of second's.

500 = vhand's cpu ticks (usually 10 ms) hex

=> 1280 tics = 12,8 sec

so we need "1F4" for 5 sec or "3E8" for 10 sec
