[-- Attachment #1: Type: text/plain, Size: 1125 bytes --]
I fixed the problems that I was having. thread_info->preempt_count is
now used to store softirq state, unlike in 2.5.20. Preempt count was
not preserved once the switch to the interrupt stack occurred. This
caused two nested softirqs and a deadlock. It is fixed now.
Any comments? Is this right for -mm, or should I try to push right to
Linus?
part of Ben LaHaise's original message:
> Below is a patch against 2.5.20 that implements 4KB stacks for
> tasks, plus a seperate 4KB irq stack for use by interrupts. There
> are a couple of reasons for doing this: 4KB stacks put less pressure
> on the VM subsystem, reduces the overall memory usage for systems
> with large numbers of tasks, and increases the reliability of the
> system when under heavy irq load by provide a fixed stack size for
> interrupt handlers that other kernel code will not eat into.
>
> The interrupt stacks are stackable, so we could use multiple
> 4KB irq stacks. The thread_info structure is included in each
> interrupt stack, and has the current pointer copied into it upon
> entry.

That'll teach me to get excited and send a patch. Sorry about the
"Only in"'s. I also think that there is still a small race window in
the code that I sent. I think that the old preempt_count need to be
placed into the new thread_info's preempt_count _before_ the stack
switch occurs.

I'd really like to see this in 2.5, if only to make massively threaded
programs using Ingo's pthreads mods even more viable, and show up those people
who think userspace threading libraries are a good idea 8)

This is a resync of the last patch for 2.5.34 that resulted from this discussion
(not the original patch):
http://lwn.net/Articles/1642/
The only change was readding the reference to task_info in the beginning of
common_interrupt. It had been dropped when we stopped messing with
preempt_count there.
I've beaten this thing with my normal array of Specweb tests and it is behaving
so far. I've booted on an 8-way with and without SMP.
