* [PATCH] pcmcia: ppc64 needs 64-bit ioaddr_t
From: Olof Johansson @ 2007-05-12 14:31 UTC (permalink / raw)
To: paulus; +Cc: linuxppc-dev, linux-pcmcia, linux-kernel
ppc64 really needs ioaddr_t to be 64-bit, since I/O addresses really
are MMIO addresses, and remapped to a high range.
While the type is exported to userspace, there hasn't been any platforms
with PCMCIA on 64-bit powerpc until now, so changing it won't regress
any existing users.

* DHCP lease renewal after boot
From: Edward Jubenville @ 2007-05-12 13:41 UTC (permalink / raw)
To: Linuxppc-Embedded
I posted a similar question in the u-boot list, but this list seems more
appropriate...
When I configure u-boot to get an IP address using DHCP, and pass that IP
through the kernel command line, doesn't the kernel need to know that it was
obtained from DHCP, so that it can maintain the lease on the IP address? Is
it allowable for the kernel to treat the command line IP address as a static
IP, and ignore the obligations of DHCP lease renewal?
I found the following in Documentation/kernel-parameters.txt. The last
sentence suggests that it is OK for the kernel to abandon responsibility of
DHCP lease renewal. This seems to violate the DHCP protocol, RFC 2131
"4.4.5 Reacquisition and expiration".
"DHCP support
CONFIG_IP_PNP_DHCP
If you want your Linux box to mount its whole root file system (the
one containing the directory /) from some other computer over the
net via NFS and you want the IP address of your computer to be
discovered automatically at boot time using the DHCP protocol (a
special protocol designed for doing this job), say Y here. In case
the boot ROM of your network card was designed for booting Linux and
does DHCP itself, providing all necessary information on the kernel
command line, you can say N here."
RFC 2131 describes a DHCPINFORM message that clients can use to announce
their static IP addresses to a DHCP server. Therefore, it matters whether
the IP address u-boot passes to the kernel is dynamic or static, because it
implies different behaviors in the kernel after boot.
How do I tell the kernel whether its command line IP address is static or
dynamic?
I'm using u-boot 1.1.4 with kernel 2.4.25 from ELDK 3.1.1

There can be, with a new DTB version -- perhaps simply
define proplen == -1 to mean "undefined" or similar.

Nice! Can you also concatenate different property

Ok, backstory.
I have a cross-compile build system called Firmware Linux
(http://landley.net/code/firmware). It's a shell script that you run to
build a system, entirely from source, for a given target platform.
Cross-compile toolchain and all.
First it builds a cross compiler from source code (gcc, binutils, uClibc, and
make headers_install from Linux), and then it does just enough
cross-compiling with that to get you a minimal native build environment (a
root filesystem containing uClibc, linux, busybox, gcc, binutils, make, and
bash), so you can build natively under emulation from thereon in. (MUCH
easier than cross compiling. Slower, but throwing hardware at the problem is
easier than throwing engineers at it. I wrote a "why cross-compiling sucks"
at http://landley.net/writing/docs/cross-compiling.html not that I have
strong opinions on the topic or anything. :)
Anyway, I have this thing building a half-dozen archtectures already, and the
ones I regularly test under are i686, x86-64, armv4l, and mipsel. (Sparc's
uClibc support is broken, and powerpc just DOESN'T LIKE ME. I'm tackling the
second first because I don't really care about sparc.)
All the other architectures (except sparc and powerpc) run under qemu. I run
the appropriate qemu variant with the "-kernel" command line option to use
the built-in bootloader, and feed them an unpartitioned ext2 image containing
the root filesystem, and all of 'em (except sparc and ppc) boot up to a shell
prompt within the emulator and are capable of building and running "hello
world".
There are idiosyncrasies. (For example I have to feed arm a scsi hard drive
instead of IDE, but that's just a different qemu command line. And for some
reason 2.6.21 broke arm's scsi support, this but worked in 2.6.20.) But
mostly, all the architectures work the same way.
Unfortunately, open hackware requires a partitioned hard drive image or it
refuses to boot. PREP looks enough like a paritioned image to fool the
firmware into letting the built-in "-kernel" bootloader of qemu work. None
of the macintosh variants do.

With qemu I can go:
qemu -kernel vmlinuzfile -hda walrus.img -nographic
And it'll load that kernel into memory and boot it, without it actually being
anywhere in walrus.img. On most platforms this bypasses the bios/firmware
entirely, but apparently powerpc can't do this (due to the need to set up a
fake hardware tree and pass it off to the kernel, or some such). And the
firmware is chock-full of built-in assumptions, and sits down and throws a
tantrum if any of them are violated.
It's kind of annoying, really. But if I could build a prep kernel, I could
work around this. Unfortunately, ARCH=ppc builds a prep kernel, but won't do
a headers_install. With ARCH=powerpc I can do a headers_installbuild a CHRP
kernel that won't boot, but not a PREP kernel.
I could teach my build script to use one ARCH for headers_install and one for
building the kernel, but that's amazingly ugly and I dont have to do it for
any of the other architectures.
I could also write a wrapper to turn CHRP into a partitioned hard drive image,
which looks like what I'm going to have to do.
> AIX stores its kernel in the PREP part, and boots from that partition

That's what I'm trying to use, yeah. ARCH=ppc does that, ARCH=powerpc does
not.
The current mercurial version of Firmware Linux builds a CHRP kernel I can't
boot. One of my users donated a config that sort of builds a PREP kernel
(attached), but you have to patch the ./cross-compiler.sh
and ./mini-native.sh build scripts to feed in "powerpc" instead of $KARCH to
headers_install.

It's slightly more compliated than that.
The CVS version of QEMU says it can emulate the following architectures:
qemu-system-ppc -M ?
Supported machines are:
g3bw Heathrow based PowerMAC (default)
mac99 Mac99 based PowerMAC
prep PowerPC PREP platform
ref405ep ref405ep
taihu taihu
Unfortunately, the powermac variants want a hard drive image (the open
hackware bios won't finish booting without it), and the other two are new
enough I haven't had a chance to try 'em yet.
The only way I've managed to build a prep kernel is ARCH=ppc. I can build a
CHRP kernel with arch=powerpc, but can't figure out how to tell qemu to boot
it (and am told formatting a fake partitioned hard drive image is The Way).

Have you tried to use parted (or fdisk) to set the first partition table
entry as type 0x41? I personally have no experience with qemu, but do
fiddle with loading images with the real IBM firmware (a lot).
What I usually end up doing is dd'ing a bootloader into the appropriate
sized 0x41 partition. Am pretty sure no GPL stuff groks PREP partitions
per se, other than seeing the part type.
AIX stores its kernel in the PREP part, and boots from that partition
(no bootloader, loads kernel directly).

Prior to the removal of struct subysystem I get two files called
'add_slot' and 'remove_slot' under /sys/bus/pci/slots/control.
With Greg's patch I get the directory /sys/bus/pci/slots/control, but
nothing under it.
Apparently John Rose is looking into it.

In theory I could feed it a power mac kernel, but I'd have to create a
partitioned hard drive image to satisfy open hackware. A prep kernel fakes
being a partitioned image sufficiently that I can use -kernel to boot.
> I'd love to see the device tree once QEMU's kernel has booted :D
So would I. :)
I'm told they've got that part working. I once managed to get a powerpc
Ubuntu ISO image to boot under qemu, I just can't _build_ a kernel that does.
(I have no idea how to create the specially partitioned hard drive image it
wants, and since I got 5 other architectures working without needing to do
that, I'm looking for a way to make a prep kernel work so I won't have to.)

Yeah, but qemu already _has_ an IDE interface, graphics card (an old western
digital something or other), and network card working. Once they got 'em
working on one platform, they can plug them into a virtual PCI bus for other
platforms.
What I wind up fighting with most when trying to get multiple platforms to
work is firmware and bootloaders. (All of which are insane, without
exception so far.) This is why I like the qemu -kernel thing, which lets me
bypass the whole issue...
Usually.

How about "not building a prep kernel at all"?
The Open Hackware bootloader used by QEMU insists on a boot partition, even
when I use "-kernel" to use the built-in bootloader. But the prep kernel is
apparently formatted to look like a boot partition, or close enough for the
firmware to recognize it. (The macintosh-style kernels require a hard drive
image in order for the firmware to like them. So I can't boot one of those
with "qemu -kernel filename" even if I build it right.)

* [PATCH 12/13] powerpc: Add bootwrapper support for Motorola PrPMC2800 platform
From: Mark A. Greer @ 2007-05-12 0:58 UTC (permalink / raw)
To: Paul Mackerras; +Cc: linuxppc-dev
In-Reply-To: <20070512004605.GA2808@mag.az.mvista.com>
The Motorola PrPMC280 and PrPMC2800 processor modules sit on an F101 or
PrPMC2800 baseboard, respectively. There are several variants of each
type of processor module which can have different amounts of memory,
amounts of FLASH, cpu frequencies, and an mv64360 or an mv64362.
The bootwrapper code for that platform reads VPD from an I2C EEPROM
to determine the processor module variant. From the variant, the
amount of memory, etc. is determined and the device tree is updated
accordingly. If the variant cannot be determined (e.g., corrupted
VPD or a previously unknown variant), the property values already
in the device tree are used.
Also, the firmware for those platforms does not completely configure
the mv64x60 host bridge so that configuration is done here.

* [PATCH 11/13] powerpc: Add DTS file for the Motorola PrPMC2800 platform
From: Mark A. Greer @ 2007-05-12 0:57 UTC (permalink / raw)
To: Paul Mackerras; +Cc: linuxppc-dev
In-Reply-To: <20070512004605.GA2808@mag.az.mvista.com>
Add the device tree source file for the prpmc2800 line of processor PMCs.
Several of the property values are updated by the bootwrapper but sane
defaults have been chosen in case the bootwrapper can't determine the
exact processor board variant. The defaults should allow the kernel
to boot despite having non-optimal device tree property values.

* [PATCH 10/13] powerpc: check cache coherency of kernel vs firmware
From: Mark A. Greer @ 2007-05-12 0:57 UTC (permalink / raw)
To: Paul Mackerras; +Cc: linuxppc-dev
In-Reply-To: <20070512004605.GA2808@mag.az.mvista.com>
From: Dale Farnsworth <dale@farnsworth.org>
check_cache_coherency() verifies that the cache coherency setting of
the kernel (CONFIG_NOT_COHERENT_CACHE) matches that left by the firmware,
as indicated by coherency-off device tree property.

* [PATCH 9/13] powerpc: Add Marvell mv64x60 PCI bridge support
From: Mark A. Greer @ 2007-05-12 0:57 UTC (permalink / raw)
To: Paul Mackerras; +Cc: linuxppc-dev
In-Reply-To: <20070512004605.GA2808@mag.az.mvista.com>
From: Dale Farnsworth <dale@farnsworth.org>
This patch adds PCI bridge support for the Marvell mv64x60 chip.
We also provide the ability to read/write the mv64x60 hotswap
register via sysfs if the hs_reg_valid property is set in the
device tree.

* [PATCH 8/13] powerpc: Create Marvell mv64x60 I2C platform_data
From: Mark A. Greer @ 2007-05-12 0:56 UTC (permalink / raw)
To: Paul Mackerras; +Cc: linuxppc-dev
In-Reply-To: <20070512004605.GA2808@mag.az.mvista.com>
From: Dale Farnsworth <dale@farnsworth.org>
This patch creates platform_device entries for the Marvell mv64x60
I2C ports, based on information contained in device tree.
This driver (like the other mv64x60 drivers) are unusual in that it
works on both the MIPS and PowerPC architectures. Because of that,
the drivers do not support the normal PowerPC of_platform_bus_type.
They support platform_bus_type instead.
