Hi, I am using UML 2.4.20 patch 3um. RH7.2 is running in the UML hosted on a RH9.0 system. The host runs on a AMD processor. The situation is I use "jiffies" to measure time in my modules inside UML. However, the difference between the captured "jiffies" is 0. One may be the operation happened fast, hence, the 0 value. The other more concerning reason may be that "jiffies" is never updated. I still need to verify the former cause. However, I am inclined towards the latter cause because I get the following messages while booting UML. Mounting proc filesystem: [ OK ] Configuring kernel parameters: [ OK ] modprobe: modprobe: Can't locate module char-major-10-135 hwclock is unable to get I/O port access: the iopl(3) call failed. Setting clock : Tue Apr 29 15:55:14 CDT 2003 [ OK ] Should I be concerned about the latter cause? Is "jiffies" the correct way to measure time in UML? waiting for reply, -- Venkatesh Prasad Ranganath, Dept.
