2.6.8-rc3-mm1

ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.8-rc3/2.6.8-rc3-mm1/

- Added David Woodhouse's MTD tree to the "external trees" list

- Dropped the staircase scheduler, mainly because the schedstats patch broke it.

We learned quite a lot from having staircase in there. Now it's time for a new scheduler anyway.

Changes since 2.6.8-rc2-mm2:

Any chance you could try the version Ingo just posted instead?

M.

I tried reverting the patch in -mm, but it was non-trivial.

I'll simply wait until -mm2 and report if the problem will still be present.

This looks like it could happen if you compile without CONFIG_SMP ... which admittedly I have not tried since the sched-domain code was introduced. Adrian, was this the situation in your case?

Yes.

Solved it for me, although running SMP on a old slow PentiumII feels a tad odd. Other than that the system is running very well, I have to try a response test and see how it feels then.

Oh I agree, the right patch is not to run SMP, but it *is* a workaround. This patch against rc3-mm1 should let you run it UP:

Thanks for finding this. Andrew, if you replace that patch with the following, it should fix it. The error occurs when CONFIG_COMPUTONE=m, so I've now built it as both built-in and a module.

I don't have this hardware, so this has been compiled but not tested.

Add pci_enable_device()/pci_disable_device(). In the past, drivers often worked without this, but it is now required in order to route PCI interrupts correctly. In addition, this driver incorrectly used the IRQ value from PCI config space rather than the one in the struct pci_dev.

sched-clean-init-idle.patch is still broken. Removing deactivate_task() from init_idle() breaks the arches that instead of doing copy_process() do kernel_thread(NULL, NULL, CLONE_IDLETASK), with all of the obvious consequences of leaving a task with a NULL program counter on one queue where it may be executed by accident and simultaneously executed on yet another cpu via the SMP trampoline, even sharing the stack between cpus.

The following applies immediately after sched-clean-init-idle.patch; I'm not convinced fork_by_hand() is worth the bloat, as a simple deactivate_task() in init_idle(), would allow all the arches to use the sparc64 method; however, this is consistent with the theme of the cleanup patch immediately preceding it. If desired, I can implement the other alternative, and teach all arches to use kernel_thread(...) and reinstate the deactivate_task() in init_idle().

It appears that init_idle() and fork_by_hand() could be combined into a single method that calls init_idle() on behalf of the caller, which would amount to something like:

task_t * __init fork_idle(int cpu)

{
	struct pt_regs regs;
	task_t *task;

	memset(&regs, 0, sizeof(struct pt_regs));
	task = copy_process(CLONE_VM|CLONE_IDLETASK, 0, &regs, 0, NULL, NULL);
	if (!task)
		return ERR_PTR(-ENOMEM);
	init_idle(task, cpu);
	unhash_process(task);
	return task;
}

Then the call to init_idle() in init/main.c would be folded into sched_init(), and so init_idle() would become private to kernel/sched.c

The following patch is merely what I used to get things working ASAP. I'll create whatever form of the init_idle() consolidation's correction is preferred against whatever tree is needed for merging.
