I was completely unaware of that feature. I hunch that many
drivers
are incapable of dealing with an unbind while they are still open.
Hmm, maybe older drivers... Anythig hotpluggable (USB, PCI, etc)
should
be in a better shape because they expect to be yanked at any time.
Whim and
Hi ,
I get the same problem as in
http://lists.ozlabs.org/pipermail/linuxppc-dev/2009-November/077394.html
posted by Jonathan.
One solution suggested is using get_user_pages(), which give a pointer of
user space buffer to the kernel module to DMA( as I got it)
But the code in teh above link
Thanks to the advice I received here, I now have my first 'real' Linux driver
up and running and am now at the optimization stage.
Is it possible to see the resources consumed by a module ? They don't show in
'ps/top' but I'm sure there are ways to see how much memory it uses (to check

i'm a bit in trouble when i try to use an external usb hard disk drive on

Sombody is able to suggest me a solution? Instead, on my iBook G4, everything
is working fine.
Actually i don't have another ppc64 to do further attempts.

If firmware allows us to map all of a partition's memory for DMA on a
particular bridge, create a 1:1 mapping of that memory. Add hooks for
dealing with hotplug events. Dynamic DMA windows can use larger than the
default page size, and we use the largest one possible.

Hello!
This series provides fixes for a couple of CONFIG_PREEMPT problems on
Power:
1. The hpte_need_flush() function accesses per-CPU variables without
protection.
2. The rtas_event_scan() function needs to use raw_smp_processor_id()
to get a starting point to avoid
The hpte_need_flush() function accesses the ppc64_tlb_batch per-CPU
variable with preemption enabled, a bug that this patch fixes. Perhaps
crudely.

The rtas_event_scan() function uses smp_processor_id() to select a
starting point in cpu_online_mask, and does so under the protection
of get_online_cpus(). This might not select the current processor
in any case, so switch to raw_smp_processor_id().

hi all,
there is the same issue here on my iBook G4 with 2.6.38-rc4 thus it
isn't an issue related to ppc64.
It's not possible to use it.

From the feedback I have received so far, the fundamental ideas in this
patch set are sane. However, the following issues are still outstanding:
1. What is the name of the no reset property?
pic-no-reset or no-reset?
2. Should we just keep the existing protected sources
Apologies for the bad post. Bad day for email ... Please ignore the
