linux.git/arch/xtensa/kernel/process.c, branch v2.6.20 Linux kernel source tree [PATCH] xtensa: fix system call interface 2006-12-10T17:55:39+00:00 Chris Zankel czankel@tensilica.com 2006-12-10T10:18:52+00:00 fc4fb2adf944d45a7f3d4d38df991c79ffdb6a43 This is a long outstanding patch to finally fix the syscall interface. The constants used for the system calls are those we have provided in our libc patches. This patch also fixes the shmbuf and stat structure, and fcntl definitions.

[PATCH] xtensa: remove extra header files 2006-12-10T17:55:39+00:00 Chris Zankel czankel@tensilica.com 2006-12-10T10:18:48+00:00 173d6681380aa1d60dfc35ed7178bd7811ba2784 The Xtensa port contained many header files that were never needed. This rather lengthy patch removes all those files. Unfortunately, there were many dependencies that needed to be updated, so this patch touches quite a few source files.

Also corrected a bugs in arm26's cpu_idle (make it actually call schedule()). How did it ever work before? Might fix the CPU hotplugging hang which Nigel Cunningham noted. We think the bug hits if the idle thread is preempted after checking need_resched() and before going to sleep, then the CPU offlined. After calling stop_machine_run, the CPU eventually returns from preemption and into the idle thread and goes to sleep. The CPU will continue executing previous idle and have no chance to call play_dead. By disabling preemption until we are ready to explicitly schedule, this bug is fixed and the idle threads generally become more robust.

Might fix the CPU hotplugging hang which Nigel Cunningham noted.

We think the bug hits if the idle thread is preempted after checking
need_resched() and before going to sleep, then the CPU offlined.

After calling stop_machine_run, the CPU eventually returns from preemption and
into the idle thread and goes to sleep.  The CPU will continue executing
previous idle and have no chance to call play_dead.

By disabling preemption until we are ready to explicitly schedule, this bug is
fixed and the idle threads generally become more robust.
