* linux-headers (powerpc v. ppc)
From: Ron Sass @ 2008-03-05 2:34 UTC (permalink / raw)
To: linuxppc-embedded
I hope this is to the right list... the recent discussion of
retiring ppc arch encouraged me to ask.
Ultimately, I'm trying to build a native PPC 405 compiler (i.e
Canadian cross). I've got a crosstool's generated cross-compiler
and I have glibc and a native bintools on my 405 root filesystem.
What I'd like to do is:
make ARCH=ppc headers_check
make ARCH=ppc INSTALL_HDR_PATH=dest headers_install
but that's not supported in the ppc tree.
So my question is, can I just ...
make ARCH=powerpc headers_check
make ARCH=powerpc INSTALL_HDR_PATH=dest headers_install
and then switch to ppc when I build the kernel?
I suspect it will work but just don't know if there is a
subtle difference that will come back to haunt me at
run-time.
Any advice would be greatly appreciated!
Ron

Preferably, fix up the patches. If that is a pain, then a followup patch
that cleans up is ok as these do not affect the correctness of the code.

Yes, that is exactly what you are meant to do. The headers
need to be compatible, otherwise we would have bigger problems
running user space programs built against an older kernel
on current machines.

I would expect it to, given that the assembler one has two branches in
the per-byte loop compared to 3 in the C version.

These comments aren't relevant to the problems you're seeing, but

First, you may want to consider moving to the version 1 dts format

The binding for gianfar mdio and ethernet devices has been updated to
better fit conventions for use of device_type and compatible
properties. Check booting-without-of.txt for the details.
Can someone from freescale please go though and update the existing
device trees, so that people stop copying the old crap.

And since this is a new port, you ought to be able to use a recent
u-boot and drop this backwards compatibility property.

Ok, so based on the above, I deduce that you have 12 external interrupt
sources:
0...4 are those nINT* things. They correspond apparently do discrete
devices on your board. You will have to create device nodes in your .dts
for these with the appropriate interrupts property for each of these.
The rest are ... hrm... weird. You -appear- to have 5 to 8 going to PCI,
to PIRQA...D. Do that mean that you have wired your connectors on the board
such that the interrupt does not depend on the actual slot number ?
Or are you doing some swizzling ?
Also, I would need to know how those external IRQs are connected to the MPIC,
I don't have the spec of that chip here. Hrm. Somebody from freescale can
help him here ?
It's also not clear to me what your interrupts 9 10 and 11 are since you
seem to only talk about PIRQA...D which is only 4 lines ..
So at this stage, that's not enough information. We need to know exactly how
you have wired things on your board, and somebody from fsl needs to tell
me how the ExtIrq are routed to the MPIC on that guy.
Once that's done, you seem to have grasped the interrupt map... for any
device or slot, you provide the mapping between idsel/pirq line on one side,
and mpic interrupt & sense on the other. For PCI, sense is always 1 for an
mpic so you mostly have to check your actual MPIC source numbers.
>From your .dts, I see you've been doing some swizzling of slots using
interrupts 1...4 ... do that correspond to EXTIRQ 5....8 ?

* dtc: Assorted improvements to test harness
From: David Gibson @ 2008-03-05 5:01 UTC (permalink / raw)
To: Jon Loeliger; +Cc: linuxppc-dev
This patch makes several small improvements to the test harness.
* An altered way of invoking shell script testcases from run_tests.sh
means scripts no longer need to me marked executable in the
repository to work properly.
* dtc.sh never did anything that was really dtc specific - with the
exception of messages, it would work equally well for any binary
that returns 0 in the successful case. Therefore, generalise dtc.sh
and fold it into run_tests.sh so we don't need a separate script any
more.
* Tweak various things so that the valgrind options are properly
propagated down to invoke dtc under valgrind when called via wrapper
scripts.
* Tweak the valgrind suppressions to work properly on a wider range of
systems (this was necessary on my machine running Ubuntu Hardy).

* dtc: Testcases for input handling
From: David Gibson @ 2008-03-05 5:22 UTC (permalink / raw)
To: Jon Loeliger; +Cc: linuxppc-dev
This patch adds some testcases checking corner cases of dtc's input
file handling. Specifically it checks that dtc works correctly when
given input via stdin, and it checks that dtc fails gracefully if
given a nonexistent input file (or directory, in the case of -Ifs
mode).

But really, does it matter for strncmp() in the kernel?
Anyway, this asm code has bugs, as do both the current C version in the
kernel, and the code I posted. We need to do better :-)

The only bug I know of in the asm code is the behaviour when the count
is zero. Do you know of any other?

* linux-next: powerpc tree merge conflict
From: Stephen Rothwell @ 2008-03-05 7:40 UTC (permalink / raw)
To: Paul Mackerras, linuxppc-dev; +Cc: linux-next
[-- Attachment #1: Type: text/plain, Size: 467 bytes --]
Hi Paul,
There was a small conflict with Linus' tree (in arch/powerpc/Kconfig) in
merging the powerpc next branch into today's linux-next tree. Commit
d9b2b2a277219d4812311d995054ce4f95067725 ('[LIB]: Make PowerPC LMB code
generic so sparc64 can use it too') conflicted with
9edddaa200df18e08fe0cf21036e8ae467b1363c ('Kprobes: indicate kretprobe
support in Kconfig'). I fixed it up.

Cheers,

* [PATCH 0/11] celleb: patchset for 2.6.26
From: Ishizaki Kou @ 2008-03-05 8:20 UTC (permalink / raw)
To: paulus; +Cc: linuxppc-dev
This is a patchset for 2.6.26 which contains following changes:
- cleanup [PATCH 1/11]
- move celleb files into platforms/cell/ [PATCH 2/11]..[PATCH 7/11]
- consolidate io-workarounds code [PATCH 8/11]..[PATCH 9/11]
- add support for celleb PCI Express [PATCH 10/11]
- bug fix [PATCH 11/11]
Consolidating io-workarounds code changes the code to support
CellBlade PCI. Please test it because I don't have any access to
CellBlade.
Best regards,
Kou Ishizaki

* [PATCH 2/11] celleb: move the base part for celleb support
From: Ishizaki Kou @ 2008-03-05 8:23 UTC (permalink / raw)
To: paulus; +Cc: linuxppc-dev
This patch moves the base code for celleb support into platforms/cell/.
All files in this patch are used by celleb-beat and celleb-native commonly.

When playing with your driver I noticed that the hdlc interfaces had
txqueuelen:0
Normal eth interfaces has txqueuelen:1000. Maybe you need to add a
txqueue to the hdlc interfaces?

PS.
The driver seems to work now, I get both TX and RX IRQs now.
