H A D | turnstile.h | diff 154937 Fri Jan 27 20:42:12 MST 2006 jhb - Add support for having both a shared and exclusive queue of threads in each turnstile. Also, allow for the owner thread pointer of a turnstile to be NULL. This is needed for the upcoming reader/writer lock implementation. - Add a new ddb command 'show turnstile' that will look up the turnstile associated with the given lock argument and display useful information like the list of threads blocked on each queue, etc. If there isn't an active turnstile for a lock at the specified address, then the function will see if there is an active turnstile at the specified address and display info about it if so. - Adjust the mutex code to handle the turnstile API changes. Tested on: i386 (all), alpha, amd64, sparc64 (1 and 3) |
