* [PATCH 0/5] powerpc: Kconfig clean patches
From: Kumar Gala @ 2009-10-16 17:21 UTC (permalink / raw)
  To: linuxppc-dev; +Cc: linux-kernel

This is a series of simple Kconfig cleans related to powerpc intended
for v2.6.33.  I'm assuming having them go via the powerpc tree is
probably the easiest.

* [PATCH] powerpc: Add a Book-3E 64-bit defconfig
From: Kumar Gala @ 2009-10-16 17:05 UTC (permalink / raw)
  To: linuxppc-dev

This defconfig's purpose at this time is to help catch compile errors
between Book-3S and Book-3E support in ppc64.  It is based on the
ppc64_defconfig with some things disabled that we dont support on
Book-3E right now (hugetlbfs, slices, etc.)

page migration only works for pages where we have some way of accounting
for all the references to a page. This usually mean using reverse mappings
(anon list, radix trees and page tables).

* [PATCH] powerpc/85xx: Fix USB GPIOs for MPC8569E-MDS boards
From: Anton Vorontsov @ 2009-10-16 16:50 UTC (permalink / raw)
  To: Kumar Gala; +Cc: linuxppc-dev, Liu Yu

This patch fixes USB GPIOs numbers for MPC8569E-MDS boards, plus
according to the latest HW Getting Started Guide (rev 3.3, pilot
boards), USB "POWER" GPIO polarity has changed, it is no longer
inverted.

This patch makes USB Host somewhat work on pilot boards, though
there are still some problems with determining devices speed and
long bulk transfers.

u-boot partition size should be 0x80000 (512 KB), not 0x8000 (32 KB).

* [PATCH] sata_fsl: Split hard and soft reset
From: Anton Vorontsov @ 2009-10-16 16:44 UTC (permalink / raw)
  To: Jeff Garzik; +Cc: linuxppc-dev, Jiang Yutang, Ashish Kalra, linux-ide

From: Jiang Yutang <b14898@freescale.com>

Split sata_fsl_softreset() into hard and soft resets to make
error-handling more efficient & device and PMP detection more
reliable.

Also includes fix for PMP support, driver tested with Sil3726,
Sil4726 & Exar PMP controllers.

[AV: Also fixes resuming from deep sleep on MPC8315 CPUs]

Also, if they don't boot out of the box report an issue on this list.

Hmm, you seem to be using physmap rather than physmap_of -- so it won't

If you're defining a standard layout for the platform that's unlikely to

Sorry, but it seems that the patch did already do the work. The other
problems were hardware problems and are not related to this patch (it
even happened without applying it). So it seems that the skb leak may be
solved with the provided patch.

Kind regards,

Right, so we could put a fixup in Linux as well to handle that case (make
sure not to blindly reverse, though, in case u-boot has already fixed it
up).

It's the dtb that the kernel sees (possibly after platform fixups, though
that's not the ideal case) that is supposed to exactly match the hardware. 
The dts is just one source (albeit the most significant one) of the data
that goes into the final dtb.

There are boards that have several orthogonal configuration options that
can't be probed -- we'd have to provide dozens (or worse) of .dts files in
order to cover all of them without any runtime fixup.  Not to mention things
like memory size and clock frequency...

> If MPC8313-ERDB REVC has a different IRQ routing, then doesn't
> it deserve its own dts? 

I'm inclined to say no, though I wouldn't object too hard in this case if
people really want it.  But we should still put in a u-boot fixup so that if
you have a new u-boot it doesn't matter which dts you use.

> Or do only *some* of the REVC boards have this

They should all have it.

:-)

Things are slowly getting better, but it'd be good for the BSP teams to hear
from customers (and not just other internal groups) saying they want more
up-to-date software that doesn't diverge as much from mainline.

And getting u-boot right before shipping it on a board is particularly
important.

What problems have you been having with upstream kernels on mpc8313erdb,
other than this IRQ issue?  It should work, though the BSP may have extra
features that haven't been pushed upstream.

That's what the group I'm in tries to make sure happens (for the
mpc8xxx/qoriq chips) -- but we're outnumbered by the BSP developers, so some
BSP features tend to be missing.  Basic board support should be there,
though.

I just booted 2.6.32-rc4 straight from Linus on an mpc8572ds yesterday. 
I've booted various upstream kernels on mpc8313erdb (typically an older rev,
though).

For what it's worth, I've used the following code in the recent past,
without any issues. This was on an 83xx, within the last few kernel
releases. I haven't tried it on the latest -rc.

Using device_prep_dma_memcpy() can trigger a callback as well, so the
interrupt feature isn't strictly needed. Just attach the callback to the
last memcpy operation.

static dma_cookie_t dma_async_interrupt(struct dma_chan *chan,
                                        dma_async_tx_callback callback,
                                        void *data)
{
        struct dma_device *dev = chan->device;
        struct dma_async_tx_descriptor *tx; 

        /* Set up the DMA */
        tx = dev->device_prep_dma_interrupt(chan, DMA_PREP_INTERRUPT);
        if (!tx)
                return -ENOMEM;

        tx->callback = callback;
        tx->callback_param = data;

        return tx->tx_submit(tx);

The key change in my kernel config was the BIG_ENDIAN=3DY.
The kernel probes the AMD chip, but it can't see the partitions.
I guess now I will have to define my mtd partitions in either FDT or
in the kernel arguments.
Which is the best way to define them? If the partitions are defined in
both FDT and bootargs, which one takes precedence?

The data isn't coming from the tty layer -- we're talking about printk.  How
do you throttle that without spinning?

I agree that it shouldn't spin when handling tty I/O.

AFAICT, the problem is NAND being accessed simultaneously with anything else
on the eLBC (at least GPCM -- not sure about UPM).  Instead of delaying the
memory-like transaction until the NAND special operation has completed, it
seems to just abort the NAND operation.

eLBC can't really tell the difference whether you've got NOR or FPGA hooked
up to a GPCM chip select, so the problem should still apply.

Indeed. I had to disable the follwing clock stuff to prevent crashing. I am
running on Rev 3 chip.

Yes this I found it odd that the mpc5121 work is so far behind.
We have two other mpc5200 based boards that I am running with 2.6.29.
They are running well.

Already done it and I got it to compile but as you hint I am having other problems.

* [PATCH] Found skb leak in mpc5200 fec on rxfifo error
From: Asier Llano Palacios @ 2009-10-16 12:01 UTC (permalink / raw)
  To: linuxppc-dev, Grant Likely; +Cc: a.arzuaga

(I'm sorry about my previous message with a legal notice, this time
I resent it with another mail server that doesn't include the legal
notice for me)

Hi all,

I finally found why in my mpc5200 based system (and in the lite5200) I
had leaks of skbs when receiving ethernet traffic at 100 Mbit/s so that
we generated an rxfifo error (to be able to get it I even reduced the
speed of the CPU using the PLL jumpers).

The problem was:

The reception packets are handled in the interrupt handler:
mpc52xx_fec_rx_interrupt. So this interrupt is being handled all the
time because we are receiving packets continuously.

The reception fifo errors are handled in the interrupt handler:
mpc52xx_fec_interrupt. This interruption is being handled very often
because we are receiving more packets that what we can handle, and that
generates a fifo reception error.

So it is very usual that the mpc52xx_fec_interrupt handler is executed
at the middle of the mpc52xx_fec_rx_interrupt handler. And I think that
it is not designed for that purpose.

The mpc52xx_fec_rx_interrupt uses bcom_retrieve_buffer and
bcom_submit_next_buffer. The mpc52xx_fec_interrupt calls to
mpc52xx_fec_reset which calls to mpc52xx_fec_free_rx_buffers and
mpc52xx_fec_alloc_rx_buffers, which at the end call bcom_retrieve_buffer
and bcom_submit_next_buffer.

Then we have two problems because of the same origin:
 - bcom_retrieve_buffer and bcom_submit_next_buffer doesn't seem to be
   atomic, so they cannot be called from one interrupt nested from
   another one being executing those functions.
 - Even if they were atomic, the mpc52xx_fec_rx_interrupt and the
   mpc52xx_fec_reset functions are not intended to be called at the
   same time.

Patch I managed to do:
 I've managed to perform a patch that avoids the leak disabling the
 irqs, but I have a remaining problem: The last  packet to be transmited
 is waiting for a packet to be received in order to egress (I don't know
 why but I detected it experimentaly).
 
Anyone with more experience can tell me what's wrong in this patch?

Thank you in advance,
Asier

This patch enables default_idle when power_save=off kernel boot
option is specified.

Earlier, this was done by setting ppc_md.power_save = NULL and hence
HMT_low() and HMT_very_low() was called. Now this is defined under
default_idle() and hence by setting boot_option_idle_override = 1,
the cpuidle registration stuff does not happen and hence default_idle
is chosen in cpuidle_idle_call.

This patch creates arch/powerpc/platforms/pseries/processor_idle.c,
which implements the cpuidle infrastructure for pseries.
It implements a pseries_cpuidle_loop() which would be the main idle loop
called from cpu_idle(). It makes decision of entering either
dedicated_snooze_loop or dedicated_cede_loop for dedicated lpar and
shared_cede_loop for shared lpar processor based on the
decision taken by the cpuidle governor.

* [v9 PATCH 7/9]: POWER: add a default_idle idle loop for POWER.
From: Arun R Bharadwaj @ 2009-10-16  9:46 UTC (permalink / raw)
  To: Peter Zijlstra, Benjamin Herrenschmidt, Ingo Molnar,
	Vaidyanathan Srinivasan, Dipankar Sarma, Balbir Singh, Andi Kleen,

  Cc: linux-arch, linux-acpi, linuxppc-dev, linux-kernel
In-Reply-To: <20091016093850.GB27350@linux.vnet.ibm.com>

* Arun R Bharadwaj <arun@linux.vnet.ibm.com> [2009-10-16 15:08:50]:

In arch/powerpc/kernel/idle.c create a default_idle() routine by moving
the failover condition of the cpu_idle() idle loop. This is needed by
cpuidle infrastructure to call default_idle when other idle routines
are not yet registered. Functionality remains the same, but the code is
slightly moved around.

* [v9 PATCH 6/9]: pSeries/cpuidle: refactor pseries idle loops
From: Arun R Bharadwaj @ 2009-10-16  9:45 UTC (permalink / raw)
  To: Peter Zijlstra, Benjamin Herrenschmidt, Ingo Molnar,
	Vaidyanathan Srinivasan, Dipankar Sarma, Balbir Singh, Andi Kleen,

* Arun R Bharadwaj <arun@linux.vnet.ibm.com> [2009-10-16 15:08:50]:

This patch removes the routines, pseries_shared_idle_sleep and
pseries_dedicated_idle_sleep, since this is implemented as a part
of arch/powerpc/platform/pseries/processor_idle.c

Also, similar to x86, call cpuidle_idle_call from cpu_idle() idle
loop instead of ppc_md.power_save.
