You're free to make it a pointer and do node affine allocations from an
init section of choice and add a hotplug handler.
But I'm not quite sure how perf is affected by size overhead on
ridiculous configs.

No, I meant "can you actually measure the perf win of this patch?". If you
did so, I missed it?
But if this patch is worthwhile, the right way to do this is make it a
cpumask_var_t, and do the alloc_cpumask_var_node() in that init routine.
Thanks,
Rusty.

Over what, the always single-ipi case, or the kmalloc case?
The thing is, we're removing that kmalloc because its somewhat of a wart
on the whole thing.

Right, and installing a hotplug handler and ... *sigh*

Hi,
Setting CONFIG_PERF_COUNTERS make my build, hang really early. Likely
before ohci1394_dma=early stuff, because firescope doesn't seem to work.
With attached config the system boots up to the point
after /etc/rc.sysinit (this is a fedora 10 system) activates the swap.
Then all I see from upstart/init is "Message from illegal source". And
the system seems to stop the boot process. Strange, isn't it?
So this is what I could capture with attached config, by inserting
"/bin/bash" into /etc/rc.sysinit after swap activation:

Hmm, this appears unimplemented on -rt, shouldn't hurt much, but could
be fixed.

Caused by CONFIG_HIGHPTE=y,
as long as TLB flushes are IPIs we really need to disable IRQs for
gup_fast() and thus will either need non-preemptible kmap or disabled
high-pte or disable the gup_fast() fast-path, which would be a shame.

Hi,
Are you interested in these BUG reports?
Without CONFIG_HIGHPTE kernel boots and seems to work correct, but I'm

sg_copy_buffer() seems to disable IRQs, however since on -rt everything
is a irq-thread and kmap is preemptible, we don't appear to have that
need.

could you edit lib/scatterlist.c line 395 and remove this line:
WARN_ON(!irqs_disabled());
?

FYI:
These patches in RT2:
rt-fix-ipi-kfree-introduce-ipi_softirq.patch
rt-fix-ipi-kfree-introduce-ipi_softirq-cleanup.patch
Cause a hard-lock when running dhcp on my 8-way AMD box.
Reverting them eliminates the issue.

These work with 2.6.29-rc4-rt2.
Also fixes serial console stall.
I applied them before RT and had to tweak these patches:
preempt-realtime-ipi-call-lock-raw.patch
preempt-realtime-x86_64.patch
Thanks!

Hi,
I got this warning, that i never saw before with a non rt-preempt

Hi,
It's an known issue on ath5k (or 80211):
http://patchwork.kernel.org/patch/1169/
So not preempt-rt related. Perhaps it has been fixed in -rc5.
