On 32 bit maybe. On 64, the pg/u/md's can be smaller. I don't really
want to have a different encoding for both types though.

Hi Ben,
I forgot to attach the patch which enables cpuidle for the rest of the
POWER platforms. Attaching it below.
So for these platforms, ppc_md.power_save will be called from from the
cpuidle_idle_call idle loop itself. Also, this cpuidle_idle_call is
not a pseries specific idle loop. It is a common loop for Intel and
PPC which use cpuidle infrastructure.
arun
This patch enables cpuidle for the rest of the POWER platforms like
44x, Cell, Pasemi etc.

* using different format for hugetlbfs
From: Kumar Gala @ 2009-12-04 7:18 UTC (permalink / raw)
To: Benjamin Herrenschmidt, David Gibson; +Cc: linux-ppc list
Ben, David,
If we want to support true 4G/4G split on ppc32 using the MSB of the
address to determine of the pgd_t is for hugetlbfs isn't going to
work. Since every pointer in the pgd_t -> pud_t -> pmd_t is point to
at least a 4K page I would think the low order 12-bits should always
be 0.
Could we use something like:
addr[0:51] || shift [52:59] || flags [60:63]
with the LSB flag being 'normal pointer' vs 'hugetlbfs mangled
pointer'. Seems like shift will at most be 64 so 8-bits should cover
it.

Ah, now I see, this is a mpc-only problem of implementation
(automatically generating stop in read function).
I couldn't find the above mentioned specification of STOP/RESTART (seems
I need new glasses) and was worried about whether my own implementation
for OCTEON is correct.
Thank you.

PCI works on Canyonlands without any problems. I just tested latest Linux

So unless I'm mistaken, you removed our powerpc "generic" idle loop that
calls into ppc_md.power_save(), and replaced it by some pseries specific
idle loops... Now what about all the other powerpc platforms ? native
970 (aka G5) ? 6xx ? Cell ? Or are you still calling ppc_md.power_save
somewhere that I missed ?

Tentative NAK... you remove the code before you put a replacement in, or
did I miss something ?
IE. That patch breaks Idle on all powerpc platform it would think..

* 'High Resolution Timer Support' enabled cause CPU usage increase!
From: hank peng @ 2009-12-04 2:47 UTC (permalink / raw)
To: linuxppc-dev
Hi,All:
CPU is MPC8548, kernel version is 2.6.31.6. When I enabled this
option, my application's CPU usage increased, then I disabled this
option, CPU usage dropped to normal level.
I also tested on 2.6.30, the result is same.

Michel, Darrick,
Apparently you are using the therm_adt746x driver, so maybe you would
be interested in testing and carrying the following patch. I've sent it
to Colin Leroy, who is listed as the maintainer for this driver, 1.5
month ago, but did not hear back.
* * * * *
The ADT746x don't have any register at sub-address 0, so better use an
existing register for the initial test read.

Right, if he's going to map it cachable he shouldn't bother with using
mem= or crap like that. And /dev/mem should just work.

If it's cachable, why don't you write yourself a little driver that
allocates memory maps it to userspace and provides you with the physical
addresses and problem solved ?

Subject: [PATCH] therm_adt746x: Record pwm invert bit at module load time
Date: Mon, 30 Nov 2009 15:47:27 -0800
Message-ID: <20091130234727.GA10295@tux1.beaverton.ibm.com>
In commit 0512a9a8e277a9de2820211eef964473b714ae65, we unilaterally zero the
"pwm invert" bit in the fan behavior configuration register. On my PowerBook
G4, this results in the fans going to full speed at low temperature and
shutting off at high temperature because the pwm invert bit is supposed to be
set.
Therefore, record the pwm invert bit at driver load time, and write the bit
into the fan behavior control register. This restores correct behavior on my
PBG4 and should work around the bit being set to the wrong value after
suspend/resume (which is what the original patch was trying to fix). It also
fixes a minor omission where the pwm invert bit correction is NOT performed
when switching into automatic mode.

yeah well ... I lifted those definitions from the old driver and didn't
feel like changing them all :-) I might do a separate patch later to
clean that up, we don't actually use a lot of those anymore since I use
pre-calculated tables, though they are good to keep as documentation.

Makes sense. I'm tempted to make that a separate patch tho, since I've
already queued up the existing one and it's just a relatively minor
performance optim.

I believe the simple patch is fine. But only testing can tell, so it's
up to you guys to test it :-)
None of the churn related to PIO that was in the previous patches is
necessary.
PIO on powerpc "appears" to work just like x86, the illusion is
maintained by the arch code. PIO resources always fit inside 32-bit,
never need to be ioremapped etc... so as long as you use the result of
pci_resource_start() and pass that (or an offset from that) to
inb/outb/intw/outw... PIO should just work, no change is required to the
driver. IE. PIO resources don't contain physical addresses. The powerpc
PCI code puts in there an offset from _IO_BASE to an already ioremapped
area mapping the PCI host bridge IO space. It can use funky pointer
arithmetic so don't be surprised if the values look like negative 32-bit
ints, but it should just work.
The only problem I can see with the driver, which is fixed by the simple
patch, is that for -MMIO-, the resources (which in the case of MMIO do
contain physical addresses) can be >32 bit, and thus must be stored into
a type of the right size before being passed to ioremap(). This is what
the one-liner patch does and according to the patch author, it was
tested and appears to work.
So I'm happy with the one liner patch. If you have more concerns, please
explain precisely what you believe will not work :-)
Cheers,
Ben.

* [PATCH 4/4] powerpc: Improve backtrace output for ppc32
From: Anton Vorontsov @ 2009-12-03 23:32 UTC (permalink / raw)
To: systemtap; +Cc: linuxppc-dev, Jim Keniston
In-Reply-To: <20091203233059.GA28186@oksana.dev.rtsoft.ru>
0x%016lx format causes a lot of unnecessary zero-padding on ppc32, so
let's use %p instead.
Before:
--- Exception: c00095c8 at 0xc02cff60 : _edata+0x1f60/0x2000 [kernel]
LR =0xc02aef58 : per_cpu__runqueues+0x0/0x400 [kernel]
[0x00000000c02cfed0] [0x00000000c00113fc] 0xc00113fc : ret_from_except+0x0/0x14 [kernel] (unreliable)
After:
--- Exception: c00095c8 at 0xc02cff60 : _edata+0x1f60/0x2000 [kernel]
LR =0xc02aef58 : per_cpu__runqueues+0x0/0x400 [kernel]
[0xc02cfed0] [0xc00113fc] 0xc00113fc : ret_from_except+0x0/0x14 [kernel] (unreliable)
p.s.
Note that the second and the third columns are dups, this is because
_stp_symbol_print(ip) also prints ip. Though, for now I wouldn't touch
this since I'm not sure if anybody depends on the current columns count
or "[]" around addresses.

* [PATCH 3/4] powerpc: Adjust registers.stp for ppc32
From: Anton Vorontsov @ 2009-12-03 23:32 UTC (permalink / raw)
To: systemtap; +Cc: linuxppc-dev, Jim Keniston
In-Reply-To: <20091203233059.GA28186@oksana.dev.rtsoft.ru>
registers.stp is missing a few small bits when running on ppc32:
* Divide register offsets by 2;
* There is 'mq' register instead of 'softe';
* long_arg() should sign-extend the result on ppc32.

* [PATCH 2/4] powerpc: Fix longlong args handling
From: Anton Vorontsov @ 2009-12-03 23:31 UTC (permalink / raw)
To: systemtap; +Cc: linuxppc-dev, Jim Keniston
In-Reply-To: <20091203233059.GA28186@oksana.dev.rtsoft.ru>
When probing 32-bits apps on ppc64 or running native ppc32, int64
parts are stored in the big endian order, e.g. foo(1LL, 2LL, 3LL)'s
args turn into:
arg1: r3 = 0; r4 = 1
arg2: r5 = 0; r6 = 2
arg3: r7 = 0; r8 = 3
For example, to restore arg1 the current longlong_arg() will perform
(r4 << 32) | r3, which is obviously incorrect. And to restore arg2 it
will do (r5 << 32) | r4, which doesn't look right as well.
This patch fixes the issue.

In-Reply-To: <20091203233059.GA28186@oksana.dev.rtsoft.ru>
_stp_arg() has an almost unnoticeable thinko in the argnum handling,
which causes it to always return u_register("r10"):
'else (argnum == 8)' should actually be 'else if (argnum == 8)'.
Though, since we check for 'if (argnum < 1 || argnum > 8)' at the
beginning of _stp_arg(), let's make it just 'else'.

* [PATCH 0/4] systemtap: Some more powerpc patches
From: Anton Vorontsov @ 2009-12-03 23:30 UTC (permalink / raw)
To: systemtap; +Cc: linuxppc-dev, Jim Keniston
Hi all,
Here are few more patches for systemtap/powerpc...
- Patches 1-3 are used to fix failing tests as reported by
testsuite/systemtap.context/num_args (thanks to Jim Keniston for
the hint);
- Fourth patch just improves backtrace output. Though, backtrace.stp
test is still failing, I'm currently investigating this.
..I need set up a bit faster machine to run the whole testsuite
(just one test takes ages to complete on a diskless 300 MHz board ;-),
and when I set it up I'll post the results.
Thanks!

I submitted a patch on similar lines several weeks ago and it wasn't
accepted on grounds that it was too tied to the powerpc platform. Below

* [RFC PATCH v2 5/6] powerpc: wii: platform support
From: Albert Herranz @ 2009-12-03 22:47 UTC (permalink / raw)
To: linuxppc-dev; +Cc: Albert Herranz
In-Reply-To: <1259880447-5008-1-git-send-email-albert_herranz@yahoo.es>
Add platform support for the Nintendo Wii video game console.
Signed-off-by: Albert Herranz <albert_herranz@yahoo.es>
---
v1 -> v2
- Get rid of show_cpuinfo hooks. Suggestion by Grant Likely.
- Drop unneeded (at this stage) empty functions. Suggestion by Grant Likely.
- Merge wii.c and wii_dev.c into a single file. Suggestion by Grant Likely.
- Use "wii" instead of "rvl" as a pr prefix. Suggestion by Segher Boessenkool.
- Assume 'mini'-like firmware environment.
