Subject: trouble locating code that increments jiffies (arm)
Date: Wed, 11 May 2011 08:22:16 -0500	[thread overview]
Message-ID: <d47c01f4b6db48194f07ec1f8306bb3b@basementcode.com> (raw)

 Hi list,

 I've been looking for the code that increments the jiffies variable as 
 well as the code that connects a timer interrupt to the function that 
 increments the variable. I'm working with the ARM architecture in case 
 that makes a difference. I was also wondering, how many jiffies are 
 there? Right now I'm finding that if I disable the local timer for the 
 boot CPU (during boot) the jiffies variable stop incrementing. I always 
 assumed the global timer was supposed to increment a single jiffies 
 variable. I'm working with an old, modified, version of QEMU so I'm 
 leaning towards a QEMU bug for this problem.

 Thanks,
 -C
