* [PATCH 0/4] DTC: Introduce better DTS literal support
From: Jon Loeliger @ 2007-10-19 17:42 UTC (permalink / raw)
To: linuxppc-dev
Folks,
This 4 part patch series for the DTC has:
0001-Reformat-grammar-rules-to-not-mix-language-syntax-an.patch
0002-Quiet-a-bogus-May-be-used-uninitialized-warning.patch
0003-Appease-the-printf-format-Gods-with-a-correct-typ.patch
0004-Begin-the-path-to-sane-literals-and-expressions.patch
The first is a pure whitespace formatting cleaning.
The second two clean compiler warnings.
The final one introduces a versioned DTS file with
support for C-like literals.

Hi,
Lots of graphics cards need their on-board BIOS to be executed to setup
the card before it can be used by linux or anything else. Some firmwares
have x86 emulation built-in to do this (CFE has it, SLOF might, U-boot
has it for some platforms but I don't know about 4xx).

BTW, what tree did you base this on? I don't seem to have the

The situation here is that the Linux RAID driver does a lot of complex things
with the pages (strips of array) using CPU before submitting these pages to h/w.
Here is where the most time is spent. Thus, increasing the PAGE_SIZE value we reduce
the number of these complex algorithms calls needed to process the whole test (writing
the fixed number of MBytes to RAID array). So, there are no user space aspects.

In-Reply-To: <20071019034904.GA4407@localhost.localdomain>
In order to achieve your goal you must do at least following things:
1) enable FRAMEBUFFER_CONSOLE option in the kernel.
2) Upon reboot make getty for the monitor terminal device (could be
tty1, but you must check).
You may add line to your inittab file
tty1::respawn:/sbin/getty 38400 tty1
Speed parameter is irrelevant and may not be needed for your getty
version.
3) To see the penguin logo you must also enable one of BOOT_LOGO defines
in kernel.
Of course I assume that framebuffer is working in your system. You may
try to check it by typing "cat /dev/zero > /dev/fb0". Terminal must be
cleaned then.
You also can try "dirty" hack to ensure framebuffer functionality. Type:
sh > /dev/tty1 2>&1 < /dev/tty1
You must get prompt on monitor (your serial will hang) and if you have
working (USB?) keyboard, you will be able to use monitor.
Thanks,
Leonid.

Uh.. most 440 systems use a serial console. It ought in theory to be
possible to use a framebuffer instead, but it wouldn't surprise me if
rather a lot of debugging was necessary.

Is this all in kernel space? or is there a user space aspect to the

I'm not sure about this property. Does the driver need to know about
this? Will this setup ever change at runtime? It seems to me that
like GPIOs and chip selects, setting you which shared PHY goes with
which device is something that should be done at board setup time.

I measured the performance of the sequential full-stripe write operations to
a RAID-5 array (P values below are in MB per second) using the h/w accelerated
RAID-5 driver.
Here are the comparative results for the different PAGE_SIZE values:
PAGE_SIZE = 4K:
P = 66 MBps;
PAGE_SIZE = 16K:
P = 145 MBps;
PAGE_SIZE = 64K:
P = 196 MBps;
PAGE_SIZE = 256K:
P = 217 MBps.

That's true, but the additional performance is an attractive thing too.

This looks like board setup behaviour. Shouldn't setting this up be
the responsibility firmware? And failing that, I think it should be
done directly by the platform setup function (in other words; make it
a helper function and call it at board setup time). Besides, you want
to provide guarantees that the board is setup correctly before the
device driver that uses it gets probed.
Cheers,
g.

Sorry, i have not had time to test, but there is a problem with the
userland serial console i want to investigate. At the latest i will test
this on monday.

* [patch 3/4] 4xx: Enable EMAC for PPC405 Walnut board
From: Josh Boyer @ 2007-10-19 14:53 UTC (permalink / raw)
To: linuxppc-dev
In-Reply-To: <20071019145307.978880000@linux.vnet.ibm.com>
This patch enables the ibm_newemac driver for the Walnut board. It fixes the
device tree for the walnut board to order the MAL interrupts correctly and
adds the local-mac-address property to the EMAC node. The bootwrapper is also
updated to extract the MAC address from the OpenBIOS offset where it is stored.

* [patch 4/4] 4xx: Enable EMAC on Bamboo board
From: Josh Boyer @ 2007-10-19 14:53 UTC (permalink / raw)
To: linuxppc-dev
In-Reply-To: <20071019145307.978880000@linux.vnet.ibm.com>
Fix some device tree omissions that prevented the new EMAC driver from
setting up ethernet on the Bamboo board correctly and update the Bamboo
defconfig.

* [patch 2/4] 4xx: Fix timebase clock selection on Walnut
From: Josh Boyer @ 2007-10-19 14:53 UTC (permalink / raw)
To: linuxppc-dev
In-Reply-To: <20071019145307.978880000@linux.vnet.ibm.com>
The current bootwrapper fails to set the timebase clock to the CPU clock
which causes the time to increment incorrectly. This fixes it by using the
correct #define for the CPC0_CR1 register.

* [patch 0/4] Small 4xx fixes for 2.6.24
From: Josh Boyer @ 2007-10-19 14:53 UTC (permalink / raw)
To: linuxppc-dev
This series of patches enables the EMAC driver for the Ebony, Walnut, and
Bamboo boards. There's also a timebase fix for Walnut.
I'll put these and a few other patches that have been sent to me into my git
tree later today and ask Paul to pull.

booting-without-of.txt has some information about describing the controller.
Scott Wood made an attempt at defining a device binding for I2C
devices, but it has not been merged into booting-without-of.txt yet.
I've copied what he wrote below. I would add to his definition the
following:
- If compatible is missing, driver should *not* fall back to the device name.
- 'compatible' list should include the exact device in the form "<mfg>,<part>"
Cheers,
g.
Here's the thread and an excerpt from Scott's original post:
http://patchwork.ozlabs.org/linuxppc/patch?id=11223
+ e2) I2C Devices
+
+ Required properties :
+
+ - reg : Unshifted 7-bit I2C address for the device
+
+ Recommended properties :
+
+ - compatible : The name of the Linux device driver that
+ handles this device. If unspecified, the name of the
+ node will be used.
+ - interrupts : <a b> where a is the interrupt number and b is a
+ field that represents an encoding of the sense and level
+ information for the interrupt. This should be encoded based on
+ the information in section 2) depending on the type of interrupt
+ controller you have.
+ - interrupt-parent : the phandle for the interrupt controller that
+ services interrupts for this device.
+
+ Example :
+
+ rtc@68 {
+ device_type = "rtc";
+ compatible = "ds1374";
+ reg = <68>;
+ interrupts = <13 8>;
+ interrupt-parent = <700>;
+ };

* re: Linux root file system with X window support for a powerpc board
From: Alan Bennett @ 2007-10-19 14:29 UTC (permalink / raw)
To: mahendravarman15, linuxppc-dev
debian:
(on x86/fedora development system) (used on 82xx)
1. debootstrap with the --foreign
i.e. debootstrap --arch powerpc etch http://mirrors.kernel.org/debian
mannually create an inittab, create/copy some default /dev entries
2. boot 74xx target with above root filesystem, run
/debootstrap/debootstrap --second-stage
Now add in packages using apt-get (or add them initially in step 1)

Hi all
Can anybody help me how to create a Linux root file system with X
window support for a powerpc 74xx based board ?
Any documents/links related to that is also welcome
Thanks in advance

If you are familiar with Gentoo based systems I would recommend [1].
