Nice write up, mind if I steal this for the devicetree.org wiki?
Sure thing, feel free to correct any mistakes too ;D

That's the idea. Communication between usermode and the driver is
limited to
simple ioctl calls and the driver receives an interrupt when certain
data has
been placed in memory blocks by the hardware (like a DMA).
Then the user prog figures out where that latest data buffer is (mmap)

Hello all,
OK, that should be all pretty straight forward, and covered by the
material in LDD and similar references. You just need to get your device
probed.
I'm not sure what you mean with that term: simply identifying that the device
works using device specific code ?
I've looked at
Another question: I just spent 10 minutes trying to find
where struct device was defined.
Dirty trick #4:
At the top of a source file (before the first include) add:
struct device { int fubar; };
Then try to compile it.
The compiler will the tell where it is defined!

Hi,
On a sort of related issue, if anyone out there has a PowerMac7,3

This implements lazy save of FP, VMX and VSX state on SMP 64bit and 32
bit powerpc.
Currently we only do lazy save in UP, but this patch set extends this to
SMP. We always do lazy restore.
For VMX, on a context switch we do the following:
- if we are switching to a CPU that currently holds the

We need to put struct call_single_data in the powerpc thread_struct,
but can't without this.
The thread_struct is in processor.h. To add a struct call_single_data
to the thread_struct asm/processor.h must include linux/smp.h. When
linux/smp.h is added to processor.h this creates an include loop
Currently we don't restore r0, r7, r8 and CTR in
fast_exception_return. This changes fast_exception_return to restore
these, which were saved anyway on exception entry.
This seems like a bug waiting to happen, plus we do it in hash_page
for 32bit anyway.

In processor.h this moves up the prefetch() functions before the

Similarly in hw_irq.h move arch_irqs_disabled_flags() to

Most of the logic for this is in the FP and VMX code, since VSX has no
additional state over these.

on also.
