2.6.8-rc3-mm1

[Andrew Morton]

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.

One of these changes means we need to be able to dereference struct

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.

On some arches, e.g. ia64, it appears that timer ticks can be taken
very, very early. In order to avoid oopsing on a prof_buffer that
hasn't yet been bootmem allocated, check prof_buffer in profile_hit().

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

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?

We have a very test IDE driver. Probably what we ideally need is a

Yes, I hit the same problem on x86_64.  But I have no patches touching
that file.  Can you send the compiler output, help me work out which patch
needs the patch?

>   a new scheduler anyway.

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.

Theses patches cause the following link errors with CONFIG_PROC_FS=n:

Ugh. Okay, here goes:

Fix up compile with CONFIG_PROC_FS=n. Accomplish this by conditionally
declaring create_prof_cpu_mask(), privatizing create_proc_profile(),
and unconditionally including profile_hit() and profile_tick().

Fix up create_proc_profile() to actually return values, and also
s/unsigned int/atomic_t/ in one last place with a casting to atomic_t
hangover.

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:
