* So long and thanks for all the fish.

  To: linuxppc-dev

Happy New Year!

I didn't survive the latest round of layoffs at Pika. So in two weeks
the smaclennan@pikatech.com email will be dead. I also will no longer
have access to a Warp.

I would like to thank all the people on this list that helped me with
with the PPC. Everybody gave freely of their time and experience. I
really appreciate all the help, it made working on the Warp very
enjoyable.

If you need to contact me for whatever reason, just use the reply
address on this email (seanm@seanm.ca). Who knows, maybe I will get
another job working with the PPC and we shall meet again!

Cheers,
   Sean

Hi Andreas,
	I tried running it multiple times but saw no crash (or error
messages in dmesg). Can you send me the crash logs? What's the behaviour
when the testcase is run on an unpatched kernel?

The watch-vfork test actually fails on my system (4 unexpected failures)
irrespective of the kernel containing the patch or not.

Thanks,
K.Prasad
P.S.: I'd been on vacation and couldn't look at this issue during then.

It should pass all four tests.  If gdb cannot even set a watchpoint it
cannot trigger the crash, of course.

* PATA_WINBOND  lost interrupt - linux-2.6.36.2 - ppc64
From: acrux @ 2011-01-03 12:08 UTC (permalink / raw)
  To: linuxppc-dev

hi,
there is a problem using new pata drivers with an old IBM Intellistation POWER 275  (9114-275 pSeries POWER4+).
These boxes are equipped with an IDE dvd-rom drive (PATA_WINBOND driver). 
0000:00:03.1 IDE interface: Symphony Labs SL82c105 (rev 05)

I can report, instead, that the old ide-cd driver BLK_DEV_SL82C105 (i tested the same scenario but with linux-2.6.32.7) works fine. Obviously it happens only when boot or try to read from the dvdrom drive.

* [PATCH 02/32] powerpc/cell: use system_wq in cpufreq_spudemand
From: Tejun Heo @ 2011-01-03 13:49 UTC (permalink / raw)
  To: linux-kernel; +Cc: Tejun Heo, Dave Jones, linuxppc-dev, cpufreq, Arnd Bergmann
In-Reply-To: <1294062595-30097-1-git-send-email-tj@kernel.org>

With cmwq, there's no reason to use a separate workqueue in
cpufreq_spudemand.  Use system_wq instead.  The work items are already
sync canceled on stop, so it's already guaranteed that no work is
running when spu_gov_exit() is entered.

Only compile tested.  Please feel free to take it into the subsystem
tree or simply ack - I'll route it through the wq tree.

Thanks.

* PowerPC MPC5200B ATA MWDMA regression
From: Roman Fietze @ 2011-01-03 13:45 UTC (permalink / raw)
  To: Tejun Heo; +Cc: linux-ide, linuxppc-dev

Hello,

When merging more recent kernel versions, tried that using v2.6.35 and
v2.6.36, into our tree (branched at v2.6.34), I detected, that MWDMA2
on the HW listed in the subject does no longer work.

So I bisected that using the original, standard kernel tree using a
minimum config using

   git bisect start v2.6.35 v2.6.34

The final result is:

360ff7833098e944e5003618b03894251e937802 is the first bad commit
commit 360ff7833098e944e5003618b03894251e937802
Author: Tejun Heo <tj@kernel.org>
Date:   Mon May 10 21:41:42 2010 +0200

    libata-sff: separate out BMDMA qc_issue

...


I double checked the failure with the latest torvalds/master as well
(b518a64983cbf2ff31), still the same issue.

The HW is an own board very close to the original Freescale
Lite5200/Lite5200B. The relevant part of the device tree source file
contains "mwdma-mode = <2>;" inside the ata section.

In the bad case the log always shows (the exact drive or drive type
doesn't matter, double checked):

Which driver is it?  You probably now want to use ata_bmdma_qc_issue()
instead of ata_sff_qc_issue() (or inherit from ata_bmdma_port_ops
instead of ata_sff_port_ops) as sff doesn't deal with BMDMA anymore.
The commit you bisected to contains all those conversions too.  Take a
look at a similar driver and look at how it has been converted
recently.  Even better, just send the driver upstream.  :-)

Good luck.

    Indeed, the driver inherits from 'ata_sff_port_ops'...

Ouch, did I forget to convert it or was it a merge timing problem?
Anyways, sorry about that.  Please go ahead and fix it. :-)

drivers/ata/pata_mpc52xx.c from the standard tree, 100% unchanged. As
I said, for the bisect I was using the original, unchanged

I'm sorry, but if I would know about the details, and would know more
about ATA I would have tried to patch pata_mpc52xx.c by myself.

It has been there for a long while. You even patched it last summer.

    It probably wasn't obvious as this driver had lived in non-BMDMA section 
of Kconfig before the recent patch:

* [PATCH] Make auto-loading of therm_pm72 possible
From: Marc Zyngier @ 2011-01-03 15:57 UTC (permalink / raw)
  To: Linux PPC Development

The therm_pm72 driver, used on the PowerMac G5 range, cannot be
auto-loaded, since the driver itself creates both the device node
and the driver instance.

Moving the device node creation to the platform setup code and
adding the necessary MODULE_DEVICE_TABLE() information allows the
driver to be automatically loaded by udev on any semi-modern
distribution.

It "fixes" a major source of problem on G5 machines where the
driver wasn't explicitely loaded by default, and the system
would automatically shutdown under load.

Tested on an Xserve G5.

    Looks like the commit that added DMA support should be thanked for the 
mischief:

Freescale MPICs do have version numbers (version registers, even).  We
should put that version (possibly along with a compatible version) in
the compatible, though, for blocks such as this which don't include the
main MPIC registers and thus the version registers.

While I don't think it affected the message unit, p4080 rev 1 has a
different version of the MPIC from p4080 rev 2 (4.0 versus 4.1, IIRC).

I don't think "mpic-" should be dropped, whether a specific chip is
added or not.  "msgr" just seems too generic, and "mpic-" tells the
reader where in the chip manual they can find information about it.

But why do we care about ordering them?  What's important is just that
you use the same one on both the sending partition and the receiving
partition.

These nodes cannot go under the mpic node, because interrupt
controllers need #address-cells = <0>.

It would be nice if the binding provided some way of partitioning
up individual message interrupts within a block.

Interrupt generation could be exported as a "service", similar to
(inbound) interrupts and gpios.

Perhaps a something like this, with "doorbell" being a new standard
hw-independent service with its own binding:

msg1: mpic-msg@1400 {
	compatible = "fsl,mpic-v3.0-msg";
	reg = <0x1400 0x200>;
	interrupts <176 2 178 2>;

	// We have message registers 0 and 2 for sending,
	// and 1 and 3 for receiving.
	// If absent, we own all message registers in this block.
	fsl,mpic-msg-send-mask = <0x5>;
	fsl,mpic-msg-receive-mask = <0xa>;

	doorbell-controller;

	// split into #doorbell-send-cells and #doorbell-receive-cells?
	#doorbell-cells = <1>;
};

some-amp-protocol-thingy {
	send-doorbells = <&msg1 0>; // generate messages on MSGR0
	receive-doorbells = <&msg1 0>; // receive messages on MSGR1
};

some-other-amp-protocol-thingy {
	send-doorbells = <&msg1 1>; // generate messages on MSGR2
	receive-doorbells = <&msg1 1>; // receive messages on MSGR3
};

Doorbell capabilities such as passing a 32-bit message can be negotiated
between the drivers for the doorbell controller and the doorbell client.

IIRC, in 2.6.21, it wasn't used on 82xx (I think there was only
arch/ppc support for 82xx, or at best 82xx arch/powerpc support was
just getting started).  2.6.21 is very old, and doing new development on
it is not recommended.

Why not work with the current kernel?
