Nice!

I take it that the microblaze is big endian? Then you just need to add
3 to the base address and everything should work without your patch.
JW> Can you please confirm if this works on PPC?
It won't as ioread/write does big/little endian byte swapping. Isn't
that done on microblaze?

I know Paul made a very conscious decisions to make the 64-bit choice
a top level config option when we moved to arch/powerpc. This is
patch effective reverts back to how we did things in arch/ppc.
I'll let it up to him to remind us why he wanted that since I dont
remember.

But there already is such a tree - It's called 'mainline'. I can see

really HAS to be a temporary thing and stuff needs to be pushed to

I posted the driver to the usb list last week:

It would be nice if you could give it a try and tell me if it works

ps3av:
- Move the definition of struct ps3av to ps3av.c, as it's locally used only.
- Kill ps3av.sem, use the existing ps3av.mutex instead.
- Make the 512-byte buffer in ps3av_do_pkt() static to reduce stack usage.
Its use is protected by a semaphore anyway.

Hi Linus, Andrew,
Here are our patches for the PS3 Audio Video Settings and Virtual Frame
Buffer
drivers for 2.6.22:
[1/8] ps3fb: thread updates
[2/8] ps3fb: atomic fixes
[3/8] ps3av: thread updates
[4/8] ps3fb: kill superfluous zero initializations
[5/8] ps3av: misc updates
[6/8] [PATCH] ps3: Make `ps3videomode -v 0' (auto mode) work again
[7/8] ps3fb: Use __func__ instead of __FUNCTION__
[8/8] ps3av: Use __func__ instead of __FUNCTION__
The last 3 are new, but they are quite simple/trivial.
Please apply. Thanks!
Gr{oetje,eeting}s,
Geert

* Re: xilinx gpio in kernel 2.6
From: Mirek23 @ 2007-05-02 12:33 UTC (permalink / raw)
To: linuxppc-embedded
In-Reply-To: <10254948.post@talk.nabble.com>
Finally I was able to incorporate the xilinx_gpio driver to the kernel 2.6
tree.
To do so I have created the file xgpio_ioctl.h which is basically identical
to
the file include/linux/ibm_ocp_gpio.h in the kernel linuxppc_2_4. The
differences are
the macro names (I have replaced IBM with X and ibm_ with x).
I have modified also arch/ppc/syslib/virtex_devices.c. I have added into
this file the entries which refer to GPIO definitions.
At the end I have modified the drivers/char/Kconfig and the
drivers/char/xilinx_gpio/Makefile.
After all I was able to compile the kernel.
I did not find however how to deal with the GPIO driver on the user's level.
I am sure that I have to use: open and ioctl function calls but I do not
know how to distinguish between
two differenet GPIO interfaces to control respectively (LEDs and DIP
switches).
I would appreciate very much any hint on that
Best Regards
Mierk

* [PATCH 6/6] powerpc: autoselect optimal -mcpu= flag by platform
From: Arnd Bergmann @ 2007-05-02 12:13 UTC (permalink / raw)
To: linuxppc-dev; +Cc: paulus
In-Reply-To: <20070502114709.074174446@arndb.de>
We can choose the -mcpu= gcc flags for compiling the kernel
based on the platform that we build for. In case of multiplatform
kernels, this chooses a setting for a common subset.
When using a platform type that can use different CPUs, a
new option CONFIG_PPC_CPU_SELECTION can be enabled to select
more specifically which CPUs the kernel will be able to
run on.
This replaces the CONFIG_POWER4_ONLY option with an much more
generic approach.
Also, when CONFIG_PPC_CPU_SELECTION is set, it is now possible
to select a CPU to tune for by means of the -mtune= option.
I tried to be very careful when coding the specific rules into
the Kconfig language, but it would be good to have a few
people sanity-checking them.

* [PATCH 4/6] powerpc: rename add_bridge to avoid namespace clashes
From: Arnd Bergmann @ 2007-05-02 11:47 UTC (permalink / raw)
To: linuxppc-dev; +Cc: paulus
In-Reply-To: <20070502114709.074174446@arndb.de>
Many platforms currently define their own add_bridge function, some
of them globally. This breaks some multiplatform configurations.
Prefixing each of these functions with the platform name avoids
this problem.

* [PATCH 1/6] powerpc: split out CPU specific options into a new Kconfig file
From: Arnd Bergmann @ 2007-05-02 11:47 UTC (permalink / raw)
To: linuxppc-dev; +Cc: paulus
In-Reply-To: <20070502114709.074174446@arndb.de>
A lot of the options in arch/powerpc/Kconfig deal with the CPU menu,
and my next patches add more to them. Moving them to a new
arch/powerpc/platforms/Kconfig.cputype file makes it easier to
follow.
There are no functional changes in here.

* [PATCH 3/6] powerpc: move 82xx/83xx/86xx Kconfig options to platform selection
From: Arnd Bergmann @ 2007-05-02 11:47 UTC (permalink / raw)
To: linuxppc-dev; +Cc: paulus
In-Reply-To: <20070502114709.074174446@arndb.de>
The cores used in the MPC82xx/83xx/86xx embedded controllers are very similar
to those in the 32 bit general-purpose processors, so it makes sense to
treat them as the same CPU family.
Choosing between the embedded platforms and the multiplatform code is
now done in the platform menu, but functionally everything stays the
same.

To: linuxppc-dev; +Cc: paulus
In-Reply-To: <20070502114709.074174446@arndb.de>
Currently, PPC64 is a top level configuration option in
arch/powerpc/Kconfig, which is somewhat unconventional.
Moving it into the CPU selection menu is a natural choice,
and is transparent to the rest of the configuration logic.

All platforms based on 6xx compatible cores should be able to
coexisting in a single kernel image and do all necessary configuration
based on the device tree.
This moves the missing 8{2,3,6}xx platforms under
CONFIG_PPC_MULTIPLATFORM to make that possible to configure.

Ah sorry, I didn't mention prep_defconfig is arch/__ppc__.
See arch/ppc/Makefile:
core-y += arch/ppc/kernel/ arch/powerpc/kernel/ \
arch/ppc/platforms/ \
arch/ppc/mm/ arch/ppc/lib/ \
arch/ppc/syslib/ arch/powerpc/sysdev/ \
arch/powerpc/lib/
So I guess we need to add the Kconfig fragment on arch/ppc also?

Ultimately we want to put the disabled cpus in sleep mode, but that
will require a suitable cache flush routine.
For now, the patch mostly looks OK, except that I would prefer that
you make power4_idle_irqs_softdisabled a separate function from
power4_idle (and choose a better name while you're there :). There
are enough differences between power4_idle and your new routine that
it would be clearer if they're separate. For one thing your new
routine wouldn't need to set _TLF_NAPPING, for another, it wouldn't
need the conditional branch at the end. Also you could do the test
for the nap capability in the caller.
Paul.
