Hi Scott,
I'm triggering an LED which is connected to port A. Are you saying that
wouldn't work once the caching is enabled?

The following series implements basic board support for GE Fanuc's SBC610, a
6U single board computer, based on Freescale's MPC8641D.
This series provides basic functionality:
- The board can boot with a serial console.
- Ethernet works, though the phys are polled.
- The PCI bus is scanned and sata functions.

Kumar & Scott: Thanks again for your comments.
I have:
- Removed all of the "device_type" entries I believe I can
- Moved the default config to new directory "arch/powerpc/configs/86xx/"
- "mac-address" changed to "local-mac-address"
- Removed un-needed #add/size and other defunct entries
- Use common interrupt routine.
Martyn

It's quite possible. What other registers are in the same cache line as
the LED, and are any of them non-memory-like? And even if all registers
in the cache line are OK with this sort of access, you need to use dcbf
afterwards.
It's usually easiest to just trust that that part of the code works (in
my experience, that's rarely where a hang actually occurs when bringing
up a new board), and resume tracing after the MMU is on and you've
inserted a caching-inhibited BAT entry.

David, are there any issues with the first patch in the series?
It would be great if you'll ack the first patch, so that I'll
respin the whole patchset with some minor fixes in the 3rd patch.

* PPC405EP errata CPU 213 (Incorrect data may be flushed from the data cache)
From: Darcy Watkins @ 2008-08-26 16:01 UTC (permalink / raw)
To: linuxppc-embedded
Hello,
The IBM/AMCC errata document recommends setting reserved bits 1 & 3 in
CCR0 as a workaround to PPC405EP errata CPU 213 (Incorrect data may be
flushed from the data cache). For a start, I just tried hacking in a
few lines of assembly code into...
arch/powerpc/kernel/head_40x.S

*/
lis r4,2f@h
...
Since I am not a PowerPC assembler guru, does this appear right?
I think that eventually I'd want to create a cpu_setup_40x.S with the
fixup code as part of a setup_cpu_405ep function and then hook this into
cputable.c, but first I want to make sure that the errata workaround is
actually taking effect (and also not being undone by later startup
code).

So, this happens first before anything else.
Without this, the boards that I've used crash pretty quickly, so it may be obvious that the status register is set properly.
As a result, you probably need to do it in the boot loader and not in the kernel proper.

* Compile new kernel for 5200B w/ ELDK
From: Albrecht Dreß @ 2008-08-26 17:01 UTC (permalink / raw)
To: LinuxPPC Embedded
[-- Attachment #1: Type: text/plain, Size: 1356 bytes --]
Hi all,
please excuse a probably really dumb question about compiling a new
kernel for a Freescale 5200B using the ELDK 4.2...
I am playing with a Lite5200B eval board. The software coming from
Freescale, including an older kernel (2.6.16.11-rt18), works fine.
I installed ELDK 4.2 on a FC box, and first compiled u-boot 1.3.4.
Wrote it to flash, and it works nicely afaict.
Then I compiled the 2.6.24.2 kernel coming with the ELDK, using the
commands "make ARCH=powerpc CROSS_COMPILE=ppc_6xx- lite5200_defconfig ;
make ARCH=powerpc CROSS_COMPILE=ppc_6xx- uImage". The kernel loads,
decompresses, but then there is no output any more after "Uncompressing
Kernel Image ... OK". The u-boot environment contains (quoted from
printenv) "bootargs=console=ttyPSC0,115200 root=/dev/mtdblock0 rw
rootfstype=jffs2 verbose" (and, again, the Freescale kernel is not
silent).
I found a message which stated that I should include
<snip>
chosen {
linux,stdout-path = "/soc5200@f0000000/serial@2000";
};
</snip>
in the file arch/powerpc/boot/dts/lite5200.dts. Recompiled, but
without success. I believe it's a minor tweak I need to add, but I
don't have a clue what. Unfortunately neither the wiki nor Google gave
answers. Can anyone enlighten me??
Thanks,
Albrecht.

There are some ethernet signals, a compact flash card detect, other LEDs
and a push button also on port A. Are those what you'd call
non-memory-like?

Where can I find out how to do that? Since I have this board working with
the old ARCH=ppc, can I copy anything from there?
Also, where would be a good place in the code to resume tracing?
Thanks for your help so far. I see now it's probably not the code for
enabling the cache that's causing the problem, it just masks my attempts
at tracing using the LED.
Cheers,
Chris.

Would any of them object to spurious reads, and writebacks of the value
that was read?

See setup_cpm_bat in arch/powerpc/kernel/head_32.S.

As soon as you can set up a BAT -- though first, I would try just
enabling the CPM debug console and see if you get anything from that.

* [PATCH -rt] powerpc/qeic: fix sleeping in atomic context

Cascade interrupts do not use threads, thus handlers are called
with interrupts disabled. This means that we must not grab regular
spinlocks, since they might sleep:

* [PATCH] PPC4xx compatible ioctl for PHY control
From: Wolfgang Ocker @ 2008-08-26 18:22 UTC (permalink / raw)
To: benh; +Cc: Linuxppc-dev
From: Wolfgang Ocker <weo@reccoware.de>

debug: add notifier chain debugging
during some development we suspected a case where we left something
in a notifier chain that was from a module that was unloaded already...
and that sort of thing is rather hard to track down.
This patch adds a very simple sanity check (which isn't all that
expensive) to make sure the notifier we're about to call is
actually from either the kernel itself of from a still-loaded
module, avoiding a hard-to-chase-down crash.

* Back port Virtex5 FPU to Virtex4?
From: Shanyuan Gao @ 2008-08-26 20:00 UTC (permalink / raw)
To: linuxppc-embedded
I am working with ML410 and have FPU (single precision) working.
However, the FPU for V5 looks more attractive because it's double
precision. So is it possible to back port the double precision FPU
to V4?

Jon Loeliger thinks this will be fixed by Kumar's DDR patches that are
about to be checked in. Please test is this is correct, and report
back if it doesn't.
Thanks.

* [RFC][USB] powerpc: Workaround for the PPC440EPX USBH_23 errata
From: Vitaly Bordug @ 2008-08-26 22:23 UTC (permalink / raw)
Cc: Stefan Roese, linuxppc-dev@ozlabs.org, linux-usb, Mark Miesfeld
A published errata for ppc440epx states, that when running Linux with both
EHCI and OHCI modules loaded, the EHCI module experiences a fatal error
when a high-speed device is connected to the USB2.0, and functions normally
if OHCI module is not loaded.
Quote from original descriprion:
The 440EPx USB 2.0 Host controller is an EHCI compliant controller. In USB
2.0 Host controllers, each EHCI controller has one or more companion
controllers, which may be OHCI or UHCI. An USB 2.0 Host controller will
contain one or more ports. For each port, only one of the controllers is
connected at any one time. In the 440EPx, there is only one OHCI companion controller,
and only one USB 2.0 Host port.
All ports on an USB 2.0 controller default to the companion controller. If
you load only an ohci driver, it will have control of the ports and any
deviceplugged in will operate, although high speed devices will be forced to
operate at full speed. When an ehci driver is loaded, it explicitly takes control
of the ports. If there is a device connected, and / or every time there is a
new device connected, the ehci driver determines if the device is high speed or
not. If it is high speed, the driver retains control of the port. If it
is not, the driver explicitly gives the companion controller control of the
port.
The is a software workaround that uses
Initial version of the software workaround was posted to linux-usb-devel:
http://www.mail-archive.com/linux-usb-devel@lists.sourceforge.net/msg54019.html
and later available from amcc.com:
http://www.amcc.com/Embedded/Downloads/download.html?cat=1&family=15&ins=2
The patch below is generally based on the latter, but reworked to
powerpc/of_device USB drivers, and uses a few devicetree inquiries to get
rid of all the hardcoded defines and CONFIG_* stuff, in favor to
defining specific quirk. The latter required to add more accurate
description into compatible field of USB node for 'sequioia' board.

* mmap and ppc460gt
From: vb @ 2008-08-27 2:26 UTC (permalink / raw)
To: linuxppc-embedded
I am trying to port an application from ppc854x to ppc440. The
application, among other things, maps register file of a PCI device
into its memory space to gain direct access to the device. mmap() is
used to accomplish the mapping.
I don't seem to be able to port this to ppc460gt: on this architecture
the PCI register space can be mapped only to 36 bit address ranges
with nonzero top nibbles. But mmap() (at least the one I have in
2.6.25) accepts only 32 bit values for addresses, hence there is no
way to map PCI space into user space.
Am I missing something and there is a way to map 36 bit address in 32
bit mode? Or maybe the kernel/library were not compiled properly and
mmap() is supposed to accept 64 bit addresses?
Any hints/suggestions will be highly appreciated,
TIA,
Vadim

In the past I've been able to use mmap64() on ppc440 to get at 36-bit
addresses. As far as I know this should still work.
Also you should be able to get at the BAR of a PCI device by using
mmap() on a resource file under /sys/devices, eg something like
/sys/devices/pci0000:00/0000:00:04.0/0000:0b:00.0/resource0
(where the bus numbers obviously depend on your system and the resource
number depends on what BAR your device has registers in)

I wonder if checkpatch-maintainers read this list, so I put Andy
Whitcroft to CC.

Right, this is supposed to work. If it doesn't, report it as a bug.

This should work as well.
The best way to do it however would be to implement a UIO device driver
for your device, see e.g. http://lwn.net/Articles/232575/.
That gives you proper control over the permissions and lets you handle
interrupts and other things as well.

Actually the _v means global variable. I would prefer to keep it.

Since this is a boolean parameter I don't know? What if I change the
name to enable_minmax. And actually use the "bool" module parameter
type?

I probably don't need both? I kinda treat the variables tied to module

Not that I have heard of. I thought it was lacking some hardware that

The choice I made here was to wait for the timer to fire rather than
to delete it. I think it is easier to just wait for it than to delete
it and try to get things back in order. Though since this is in a
module exit routine it probably does not matter. Also I would have to
check whether there was an analogous HRTimer call and call the right
one.
