The main problem is that in the feature of MPC8610 you can find:
Two synchronous serial interface (SSI) controllers for I2S or AC97
audio inputs/outputs
while in MPC5200b's feature there's only:
I2S (up to three)
However the main difference features:
MPC5200B: http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=MPC5200B&nodeId=0162468rH3bTdG0898
MPC8610:
http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=MPC8610
What do you think on this difference?

* Xilinx git tree, LLTemac driver
From: Magnus Hjorth @ 2008-03-04 9:57 UTC (permalink / raw)
To: linuxppc-embedded; +Cc: git
Hi,
I'm trying to compile the Linux kernel from the Xilinx git tree
(linux-2.6-xlnx) and am having some trouble with the LLTemac driver, =
having
to do with MAC address settings.=20
There seems to be two routines getting the MAC address in different =
ways.
The xtenet_probe function tries to access an extern bd_t __res, the type
bd_t doesn't exist in the powerpc tree which causes the compilation to =
fail.
Then there is the xtenet_of_probe function which uses =
of_get_mac_address.
What confuses me is that both the regular and the OF driver is =
registered in
the xtenet_init function, I would have expected it to be either/or.=20
Can I expect under the powerpc arch and supplying a .dts file, that the
xtenet_probe function will never be called?=20
Best regards,
Magnus

Hi Andrew,
The 2.6.25-rc3-mm1 kernel panics while bootup on power box. The machine booted up
without the panic on the third attempt, but badness call trace were seen while running
tests
1) The kernel panic on first attempt

* RE: I2S driver
From: Pedro Luis D. L. @ 2008-03-04 13:23 UTC (permalink / raw)
To: linuxppc-embedded
In-Reply-To: <766668.28874.qm@web23115.mail.ird.yahoo.com>
Ok, here down is the code I told you.
A few considerations before:
- As I told you, it is very bad commented, sorry. I'm still working on it.
- It's is not an alsa driver, but it copies data to the PSC working as SPI=
mode (it is not I2S but you only need to change the PSC configuration).
- Its purpose is to establish a dma task to copy the data from a buffer to=
the PSC, where I had attached a Digital to Analog Converter that into soun=
d through a speaker.
- Data alignment is imposed by DAC requirements.
- Clock configuration is fixed to 44.1 Khz, so audio data must be sampled =
using that frequency. Data must be also mono (only one converter attached).
- This module is part of a mayor project to stream audio data through ethe=
rnet, so it provides a function to copy audio data to audio buffers. If the=
re's no data to copy, it copies a null buffer to keep silence.
- What can you find useful in this code? Configuration steps to establish =
DMA Tasks and PSC configuration.
- After the module I send you also the code from another module that estab=
lishes PSC as I2S configuration. Clocks where adjusted to send the audio da=
ta also at 44.1 Khz as fine tunned as possible due to communication require=
ments of the attached DAC in that hardware.
And finally, here is the code:

* RE: Xilinx git tree, LLTemac driver
From: John Linn @ 2008-03-04 14:21 UTC (permalink / raw)
To: Magnus Hjorth, linuxppc-embedded; +Cc: git
In-Reply-To: <000f01c87dde$30ee1460$92ca3d20$@se>
Hi Magnus,
I just applied the change to the git tree for getting the mac address =
from the board data and it looks like I should have taken into account =
the powerpc arch also as I was building and testing ppc arch.
It looks like #ifndef needs to be added around the use of the __res for =
copying the mac address from the board data so that it doesn't do that =
in the powerpc arch.
#ifndef CONFIG_OF
memcpy(ndev->dev_addr, ((bd_t *) &__res)->bi_enetaddr, 6);
memcpy(pdata->mac_addr, ((bd_t *) &__res)->bi_enetaddr, 6);
#endif
The #ifndef may also be needed around the extern for __res.
I'll test these changes.
Thanks,
John

Subject: Xilinx git tree, LLTemac driver
Hi,
I'm trying to compile the Linux kernel from the Xilinx git tree
(linux-2.6-xlnx) and am having some trouble with the LLTemac driver, =
having
to do with MAC address settings.=20
There seems to be two routines getting the MAC address in different =
ways.
The xtenet_probe function tries to access an extern bd_t __res, the type
bd_t doesn't exist in the powerpc tree which causes the compilation to =
fail.
Then there is the xtenet_of_probe function which uses =
of_get_mac_address.
What confuses me is that both the regular and the OF driver is =
registered in
the xtenet_init function, I would have expected it to be either/or.=20
Can I expect under the powerpc arch and supplying a .dts file, that the
xtenet_probe function will never be called?=20
Best regards,
Magnus

I did figure out htat lockdep only complains about inonsistent locking
state when PREEMPT_RT paches are applied.
Now I just need some help interpreting this output so I can find what
lock and why it is inconsitent.
I _really_ want to run the rt patches...

I'm not getting a crash but I am getting this:
start_kernel(): bug: interrupts were enabled *very* early, fixing it
...and you're getting a null pointer access here (in do_IRQ):
irq = ppc_md.get_irq();
Are we somehow enabling interrupts before we've setup ppc_md.get_irq?

yes, I think so:

It helps. Thanks a lot .. :) ...
After installing the kernel with your patch, and booting to it, I
successfully ran the machine into sleep mode, several times: On a
console, after booting, and with no-one logged in. On a
KDE-Login-screen, with root logged in on a console. And just a few
minutes ago in a fully working KDE/KDM X environment.
Pressing the power button on this machine put the system to sleep, and
it resumed when pressing the same button again ...
I uploaded this fresh kernel .deb, patched with your code, up to
rapidshare:
http://rapidshare.com/files/96992135/linux-image-2.6.25-rc3-g7704a8b-with-ben.s-pmu-patch_2008.02.29_powerpc.deb.html
md5sum for the file above is 7a7613e0c52e179acf7caacaa3890901
Please note - my favorite part - this kernel does not have an initrd
image included .. :)
I attach my /etc/modules file, just in case ...
For those not familiar to rapidshare procedures: Just choose something
like "Free" on the page above, wait a few secs, then chose an
appropriate server near you, and type in the code you see in the image.
I don't have my own web space for binaries like this, so sorry if this
is a little annoying ...
For those not subscribed to linuxppc-dev@ozlabs.org:
Here's Ben's original email, with the patch:
http://patchwork.ozlabs.org/linuxppc/patch?order=state&id=17107
Thanks again for your work, Ben .... :)
Last, but certainly not least: Thanks Gaudenz, for pointing me to
"git bisect", for your response as a whole to the Debian powerpc list
... :)
My public key can be found with the 'keyserver' URL in the signature ..
Best Regards

* [PATCH 1/4] Emerson KSI8560 base support
From: Alexandr Smirnov @ 2008-03-04 16:33 UTC (permalink / raw)
To: linuxppc-dev
In-Reply-To: <20080304162322.GA19634@ru.mvista.com>
The KSI8560 is a single compact, mid-, or full-size Advanced Mezzanine Card
(AdvancedMC™) based on the Freescale™ Semiconductor MPC8560 PowerQUICC III™
microprocessor. This product will serve in data and signaling applications such
as signaling gateways (SGW) and softswitch signaling interface cards.
The board has altera maxii CPLD, that is used to obtain and manage board
configuration. Also there are two SCC UART serial consoles and FCC ethernet,
that is routed to the front panel, while other ethernet controlers (TSEC's) are
routed to the backplane.

* RE: Xilinx git tree, LLTemac driver

Magnus,
The change that broke the lltemac driver was very recent, you should be able to check out a slightly earlier version to avoid the problem.
We've been following the migration pattern where drivers advertise platform devices *and* of devices. In ARCH=ppc, only platform devices will ever get created and bound to the driver. In ARCH=powerpc, only of devices will get created and bound.
Note that the ARCH=powerpc support is very new (and as evidenced by the bug you found, it hasn't been tested as much)...
If you have successes (or more failures), we'd appreciate hearing about them.
Steve

Subject: Xilinx git tree, LLTemac driver
Hi,
I'm trying to compile the Linux kernel from the Xilinx git tree
(linux-2.6-xlnx) and am having some trouble with the LLTemac driver, having
to do with MAC address settings.
There seems to be two routines getting the MAC address in different ways.
The xtenet_probe function tries to access an extern bd_t __res, the type
bd_t doesn't exist in the powerpc tree which causes the compilation to fail.
Then there is the xtenet_of_probe function which uses of_get_mac_address.
What confuses me is that both the regular and the OF driver is registered in
the xtenet_init function, I would have expected it to be either/or.
Can I expect under the powerpc arch and supplying a .dts file, that the
xtenet_probe function will never be called?
Best regards,
Magnus

Pedro wrote:
Ok, here down is the code I told you.
A few considerations before:
- As I told you, it is very bad commented, sorry. I'm still working on it.
- It's is not an alsa driver, but it copies data to the PSC working as SPI mode (it is not I2S but you only need to change the PSC configuration).
- Its purpose is to establish a dma task to copy the data from a buffer to the PSC, where I had attached a Digital to Analog Converter that into sound through a speaker.
- Data alignment is imposed by DAC requirements.
- Clock configuration is fixed to 44.1 Khz, so audio data must be sampled using that frequency. Data must be also mono (only one converter attached).
- This module is part of a mayor project to stream audio data through ethernet, so it provides a function to copy audio data to audio buffers. If there's no data to copy, it copies a null buffer to keep silence.
- What can you find useful in this code? Configuration steps to establish DMA Tasks and PSC configuration.
- After the module I send you also the code from another module that establishes PSC as I2S configuration. Clocks where adjusted to send the audio data also at 44.1 Khz as fine tunned as possible due to communication requirements of the attached DAC in that hardware.
And finally, here is the code:
#define SPI_DBG
#ifdef SPI_DBG
#define DBG(x...) printk("(debug) " x)
#else
#define DBG(x...)
#endif
#include
#include
#include
#include
#include
#include
.....
Thanks for code.
But why i can't see library?

You'll send me another code?
And what about my file lite5200b.dts?
I must enable some like this?
// PSC3 in CODEC mode example
//i2s@2400 { // PSC3
// device_type = "sound";
// compatible = "mpc5200b-psc-i2s";//not 5200 compatible
// cell-index = <2>;
// reg = <2400 100>;
// interrupts = <2 3 0>;
// interrupt-parent = <&mpc5200_pic>;
//};

They were being used as condition registers rather than GPRs.

Same reason most of the rest of the kernel is in C rather than assembly.
Of course, a better question is why we don't just link libgcc...

We added an FAQ entry[1] to our DULG documentation. And just as a
reminder, there is also an ELDK mailing list for such questions[2].

Yes, we are - it's the semaphore rewrite which is doing this in
start_kernel(). It's being discussed.
Enabling interrupts too early on powerpc was discovered to be fatal on
powerpc years ago. It looks like that remains the case.

Sure. Just to double-check, this is with SLAB, right? Do you see this with SLUB?

* [patch 00/16] PCI: consolidate several pcibios_enable_resources() implementations, v3
From: Bjorn Helgaas @ 2008-03-04 18:56 UTC (permalink / raw)

This series replaces most of the arch-specific pcibios_enable_resources()
implementations with a single generic pci_enable_resources().
I think this is ready for -mm, but of course, I'm still interested in
any other comments.
Changes between v2 and v3:
- Renamed the generic version to pci_enable_resources(), to keep
pcibios_* names for arch-specific code (suggested by Kyle, thanks).
- I reorganized this series into a single PCI patch that adds the new
generic version, followed by a bunch of patches that individually
convert each arch over to use it.

Use the generic pci_enable_resources() instead of the arch-specific code.
Unlike this arch-specific code, the generic version:
- skips resources unless requested in "mask"
- skips ROM resources unless IORESOURCE_ROM_ENABLE is set
- checks for resource collisions with "!r->parent"

Each architecture has its own pcibios_enable_resources() implementation.
These differ in many minor ways that have nothing to do with actual
architectural differences. Follow-on patches will make most arches
use this generic version instead.
This version is based on powerpc, which seemed most up-to-date. The only
functional difference from the x86 version is that this uses "!r->parent"
to check for resource collisions instead of "!r->start && r->end".
