setbits8() and clrbits8() use a bitmask as second argument.
setbits8(&i2c_reg->i2com, 0x80) will set bit 7 on the i2com register but
leave bit 0 untouched. Likewise, clrbits8(&i2c_reg->i2mod, 1) will clear bit 0.

Opps, there is a bug in this patch. The file pika.h is not included. I
have attached it below, but a simpler solution might be to just delete
it from this file. It is not required to build the kernel.
The file currently contains the exported dtm functions. These functions
are only used by the telephony driver, which is not in the mainline
kernel.
Cheers,
Sean

You're using arch/ppc which is depreciated. You should move to using
arch/powerpc (set ARCH=powerpc when compiling). Devices are then
enabled in the device tree source file
arch/powerpc/boot/dts/lite5200b.dts.
Many things have changed with MPC5200 support in the last year, you
should also use the latest kernel release (2.6.25.2 when it is
released. If you use 2.6.25.1, then there is a trivial bug in the psc
serial port driver that you'll need to fix. I'll include the link to
the patch below)

Fedora uses a newer Xorg (1.5.0 RC1) then Ubuntu. It seems that the
detection/scanning code was changed. For me, it crashes right behind "using
VT number 7", where a file in /sys/bus/pci is accessed (which of course does
not exist), so its not related to the other mentioned bugs. I'm hesitating to
file a fedora bug report, because the default kernel works. It's more a Xorg
bug to assume everyone has PCI ...

I cannot make an informed judgement on this.
ACK, and pass through platform tree, if all platform peeps are happy.

I've prepared another path to add the support for the sam440ep;
shortly I've merged arch/powerpc/boot/sam440ep.c in
arch/powerpc/boot/cuboot-sam440ep.c; I've inserted the code to make
the rtc works directly in arch/powerpc/platforms/44x/sam440ep.c (so
there isn't any arch/powerpc/sysdev/sam440ep.c anymore), and I've
cutted away the nasty hack (dma-mapping.h and memmalloc.c) to make the
sound works.

* Linux for ml410
From: mojtaba @ 2008-05-06 17:29 UTC (permalink / raw)
To: linuxppc-embedded
In-Reply-To: <fa686aa40801071302u78d01f11y5c489553e06c0c01@mail.gmail.com>
Dear All,
I am trying to compile Linux 2.6.25(which I got from git.xilinx) for ML410
board and I have a problem during compilation. This is the error message:
CC arch/ppc/platforms/4xx/xilinx_generic_mlxxx.o
arch/ppc/platforms/4xx/xilinx_generic_mlxxx.c: In function
'virtex_device_fixup':
arch/ppc/platforms/4xx/xilinx_generic_mlxxx.c:31: error: dereferencing
pointer to incomplete type
make[1]: *** [arch/ppc/platforms/4xx/xilinx_generic_mlxxx.o] Error 1
make: *** [arch/ppc/platforms/4xx] Error 2
it seems that xlltemac_platform_data structure is not recognized by the
compiler so it cannot dereference it. I do not know what this structure is
and where it has been defined. I really appreciate if you can help me.
Best regards,
Mojtaba

I'm guessing you used the standard BSP generation process, which
overwrites files in the kernel. Instead, you should generate the BSP
into a dummy directory and copy only the xparameters_*.h file over to
the kernel. This is all that is needed in the git tree, since it
contains all of the required drivers.

Yes, but this is a symptom of a separate problem, which is that it is
sometimes valuable to generate an optimized kernel configuration for a
particular FPGA system. First order, I'm more concerned about getting a
kernel which is generic and can work with (more or less) any device
tree.

* porting pci driverfrom arch=ppc on kernel 2.6.16 to arch=powerpc on 2.6.24...
From: Mike Timmons @ 2008-05-06 17:39 UTC (permalink / raw)
To: linuxppc-embedded
[-- Attachment #1: Type: text/plain, Size: 1218 bytes --]
I have a framebuffer driver for the Fujitsu CoralP that registers fine
with the PCI bus and operates for my new arch=powerpc 2.6.24 build. The
only thing that failed when jumping from arch=ppc on my 2.6.16 kernel to
my new 2.6.24 kernel is the interrupt request. While testing other
functionality I simply compiled-out the interrupt request because it is
not always critical for basic frame buffer operation. I'm back to
wanting the interrupt.
Specifically, I have a lite5200b-based board in both cases (2.6.14 and
2.6.24 kernels). Under the old ppc scheme I obtained irq=1 via a call to
pci_read_config_byte(pci_dev, PCI_INTERRUPT_LINE, &irqnum).
Under my new powerpc kernel 2.6.24 I obtain irq=0 and the subsequent
interrupt request fails. Also, a hard-coded irq=1 fails too. I know this
is an issue with NOT querying the device tree, but I'm not sure what to
specify in lite5200b.dts, or what property I need to query to get the
correct pci interrupt.
If anyone is familiar with lite5200b.dts, is all the info I need already
in there, or do I need to add my pci device? I've done some mucking
around in the dts file but I'm not a pci expert so I am a bit confused.

Great. Otherwise the patch looks pretty good in my review. I'll queue
it up for 2.6.27.

Hmm, I tend to agree. Certainly the address-cells and size-cells can
go. Part of the nastiness is that I'm trying to maintain a modicum of
backward compatibility at the moment in the device tree generator. This
structure allow the dcr@0 node to have ranges; and the tft node to have
a properly translated reg =3D <> property for the existing driver which
only understands mmio. I don't think it really works for the opb2dcr
bridge to be a bridge and a dcr-controller at the same time. :) This
structure is also very similar to what is generated if the
dcr-controller is native from the processor (there's just no bridge).

Yup, it's exactly this problem I'm trying to fix in the case of the tft
driver.

Don't know if I like this, since it obscures the types of the
interfaces.

Don't do this; use pci_dev->irq instead.
If that value doesn't work, check your interrupt-map in the pci node of
the device tree.

Not really... In this case 'faster' means 'faster ICAP core' not 'faster
processor':
This is really something that is bounded by the number of cycles.

* [PATCH 1/4] [v5][POWERPC] refactor dcr code
From: Stephen Neuendorffer @ 2008-05-06 18:29 UTC (permalink / raw)
To: jwboyer, benh, grant.likely, linuxppc-dev, sfr
In-Reply-To: <20080506134006.62900cce.sfr@canb.auug.org.au>
Previously, dcr support was configured at compile time to either using
MMIO or native dcr instructions. Although this works for most
platforms, it fails on FPGA platforms:
1) Systems may include more than one dcr bus.
2) Systems may be native dcr capable and still use memory mapped dcr interface.
This patch provides runtime support based on the device trees for the
case where CONFIG_PPC_DCR_MMIO and CONFIG_PPC_DCR_NATIVE are both
selected. Previously, this was a poorly defined configuration, which
happened to provide NATIVE support. The runtime selection is made
based on the dcr controller having a 'dcr-access-method' attribute
in the device tree. If only one of the above options is selected,
then the code uses #defines to select only the used code in order to
avoid introducing overhead in existing usage.

[v4]
Converted flags to be DCR_HOST_*
Added WARN_ON in case someone forgets to call MAP_OK()
Fixed dealing with the dcr-access-method correctly, which was still
off in the wrong patch.
[v5]
Fixed leaked reference to the device tree.

You're right. I mainly copied from of_gpio.h without too much thinking :(.

Remove #ifdef CONFIG_OF_I2C as this breaks module compilation.
Drivers using this header should depend on OF_I2C anyways, so
there's no need to make this conditional

* [RFC] gianfar: low gigabit throughput
From: Anton Vorontsov @ 2008-05-06 19:20 UTC (permalink / raw)
To: netdev; +Cc: linuxppc-dev
Hi all,
Down here few question regarding networking throughput, I would
appreciate any thoughts or ideas.
On the MPC8315E-RDB board (CPU at 400MHz, CSB at 133 MHz) I'm observing
relatively low TCP throughput using gianfar driver...
The maximum value I've seen with the current kernels is 142 Mb/s of TCP
and 354 Mb/s of UDP (NAPI and interrupts coalescing enabled):
root@b1:~# netperf -l 10 -H 10.0.1.1 -t TCP_STREAM -- -m 32768 -s 157344 -S 157344

206848 10.00 13539 354.84
Is this normal?
netperf running in loopback gives me 329 Mb/s of TCP throughput:
root@b1:~# netperf -l 10 -H 127.0.0.1 -t TCP_STREAM -- -m 32768 -s 157344 -S 157344

212992 212992 32768 10.00 329.60
May I consider this as a something that is close to the Linux'
theoretical maximum for this setup? Or this isn't reliable test?
I can compare with teh MPC8377E-RDB (very similar board - exactly the same
ethernet phy, the same drivers are used, i.e. everything is the same from
the ethernet stand point), but running at 666 MHz, CSB at 333MHz:
|CPU MHz|BUS MHz|UDP Mb/s|TCP Mb/s|
------------------------------------------
MPC8377| 666| 333| 646| 264|
MPC8315| 400| 133| 354| 142|
------------------------------------------
RATIO | 1.6| 2.5| 1.8| 1.8|
It seems that things are really dependant on the CPU/CSB speed.
I've tried to tune gianfar driver in various ways... and it gave
some positive results with this patch:
diff --git a/drivers/net/gianfar.h b/drivers/net/gianfar.h

Basically this raises the tx interrupts coalescing threshold (raising

That is +21 Mb/s (14% up). Not fantastic, but good anyway.
As expected, the latency increased too:
Before the patch:
--- 10.0.1.1 ping statistics ---
20 packets transmitted, 20 received, 0% packet loss, time 18997ms
rtt min/avg/max/mdev = 0.108/0.124/0.173/0.022 ms
After:
--- 10.0.1.1 ping statistics ---
22 packets transmitted, 22 received, 0% packet loss, time 20997ms
rtt min/avg/max/mdev = 0.158/0.167/0.182/0.004 ms
34% up... heh. Should we sacrifice the latency in favour of throughput?
Is 34% latency growth bad thing? What is worse, lose 21 Mb/s or 34% of
latency? ;-)
Thanks in advance,
p.s. Btw, the patch above helps even better on the on the -rt kernels,
since on the -rt kernels the throughput is near 100 Mb/s, with the
patch the throughput is close to 140 Mb/s.

* RE: porting pci driverfrom arch=ppc on kernel 2.6.16 to arch=powerpc on 2.6.24...
From: Mike Timmons @ 2008-05-06 19:27 UTC (permalink / raw)
To: linuxppc-embedded
In-Reply-To: <48209F79.70506@freescale.com>
Scott,
Thanks for the quick answer. I did try this. I successfully get the
interrupt (virq=3D16) but it then fires continuously, immedetely =
following
the request_irq call.
My old ppc driver calls request_irq with flags SA_SHIRQ | SA_INTERRUPT
(0x20000000 | 0x04000000 ). I can't find equivalencies in the new
powerpc 2.6.24 kernel.
The only flag I'm passing to request_irq under the new 2.6.24 is
IRQF_SHARED.
I'm wondering if some interrupt type setting is mucked up, hence the
continuous interrupts. I only expect to receive this interrupt in
response to an error on my coralP, so I shouldn't see the interrupt at
all immediately following the interrupt request.
Any ideas? Thanks again,
Mike

Don't do this; use pci_dev->irq instead.
If that value doesn't work, check your interrupt-map in the pci node of=20

In-Reply-To: <48209F79.70506@freescale.com>
If I'm not supposed to read the interrupt using config_read, should I
also not be writing to the host register on the coral P to clear the
interrupt?
Should I instead be using some PCI helper functions?=20
I think I now have a valid interrupt, but seeing it fire continuously
when I know when-and-how it is supposed to fire is the problem now.
Obviously some of the code in the legacy driver for 2.6.16 ppc is not
correct now.
I suspect is it within the MB86290FB_WRITE_HOST_REGISTER() macros that
are used to manipulate the interrupts mask register within the CoralP
PCI graphics controller.=20
Please advise if there is some pci API I should be using to manipulate
this and other registers under the 2.6.24 powerpc kernel.
I do have a few books here with PCI examples but the interrupt
information is sparse.
Thanks again.

No, clearing interrupts is device-specific.
Have you verified that the device does not think it's generating an
interrupt during the interrupt storm? Do other PCI cards work?
