Well, this code has been in Geoff's git tree for a while, and it's been several
weeks ago I got complaints (which have been adressed by adding displays to the
quirk database). The new kboot (from Distro Kit 1.4.1) also uses it.
The only 100% (sic) mode is 480p (actual usable resolution is 576x384), which
is quite limited due to the very low resolution. This is what the current
mainline kernel uses by default, causing complaints from people who don't like
their shiny expensive full-HD displays being driven by 480p by default.
Furthermore Geoff is working on a way to configure the video mode for
otheros.bld (cfr. the tool to change the default kernel command line on an
ia32 kernel image ages ago), and petitboot (which is intended to replace the
current kboot boot loader environment) allows to change the video mode using
a simple key press if you get a blank screen.

Ta.
In not too long, I expect to have a series of patches getting libfdt
ready for use in the kernel. A new patch with various makefile
cleanups including the lexer name patch will be part of that.

Ok, I have built my library from its source RPM as you have stated.
Specifically, I have followed the procedure in section "3.7.
Rebuilding ELDK Components". First I have installed source RPMs and
then rebuilt the binary target RPM. However, as I have followed the
compiler messages I recognized that host gcc is called instead of
cross gcc.
Considering that my PATH was set following the advice in section "3.7.
Rebuilding ELDK Components" as "<ELDK_root>/usr/ppc-linux/bin"
directory is before "/usr/bin" what could be the problem?
Thanks and regards...

Advantages as compared to what?
-- Debian on Intel?
+++ powerpc has better RAS features than Intel, for example,
my favorite, PCI error handling and recovery, or hotplug cpu,
dynamic LPAR configuration, etc.
-- SuSE/RedHat on PowerPC?
+++ SuSE/RedHat offer formal support, for $$$, which debian/ubuntu do not
-- AIX on pSeries?
+++ AIX has various "enterprise" features that Debian does not.
You might try talking to RedHat/SuSE product support, and also to IBM
pSeries sales.

The following properties changed semantics and no heuristics are
employed to check for the old vs new:
(1) tces changed from virtual to real
(2) cpus spin on physical (hw id) not logical (0-n)
Other changes in that series
(3) 0->klimit is not a memreserve in the tree (we now allow overlapping
reserves, but not at the time)
(4) rtas properties are in a different location (but both could exist)

So trying to boot 2.6.9 (2004-10-18 cutoff) kernel from a tree for
2.6.10 would fail, and vice versa. But a 2.6.10 kernel can boot a v1
tree with properties, memreserves, and cpu ids that it expects, getting
the boot-cpuid from the extra property in the tree.
Is that compatible? If you only are talking about parsing the tree it
is.

That's not what I meant... you have two mapping drivers enabled, and
the pq2fads driver might be doing something other that what you

Yep, I think I agree. Most pseries systems have a small two-line
LCD display. Right now, the code that talks to it is implemented in
rtas_progress(). It has this name because its used only for printing
out boot progress messages. This is great for debugging hangs, but
its not othrewise used.
I suppose it would be nice to have a "geeric" interface to the thing,
and, after a quickie skim of the code, the celleb display looks similar
enogh that this abstraction could be made.

It is not that bad. If a bootloader is configued to use autodetection
so that it is shown at best video mode, then it should have advertised
key sequences to default to known video modes, with at least a 480p 'safe'
mode.
Second stage kerenls can be booted with a videomode appended on the
command line, and all kboot.conf's should have a 480p 'safe' mode
entry.

There seem to be two choices:
1) enable CONFIG_PM in those arches that care about recovering from PCI
errors. (Yuck)
2) remove the ifdef CONFIG_PM from around pci_restore_msi_state() in
rivers/pci/msi.c
I'd go for choice 2, but I thought I'd ask first ...

* [PATCH v3] Make instruction dumping work in real mode.
From: Scott Wood @ 2007-09-27 18:00 UTC (permalink / raw)
To: paulus; +Cc: linuxppc-dev
On non-book-E-or-4xx, exceptions execute in real mode. If a fault happens
that leads to a register dump, the kernel currently prints XXXXXXXX because
it doesn't realize that PC is a physical address.
This patch checks the state of the IMMU, and if necessary converts PC into a
virtual address.

44x is Book-e :)
all you need is a ifndef CONFIG_BOOKE.

Doesn't CONFIG_44x select CONFIG_BOOKE? Maybe you meant CONFIG_40x?

The call to msleep() is inside a block protected with
:#define in_interrupt() (irq_count())
if (!in_interrupt)
The stack trace looks like it is in a timer interrupt so shouldn't
irq_count be non-zero?
Could there be some lack of coordination on irq_count and the timer
tick with the preempt patch applied? Or does irq_count() not count
soft irqs?
(!in_interrupt) may be the wrong way to protect this code.

Heeheehee! That was the *last* version of the patch. :-)
40x *does* have real mode, so CONFIG_40x is not appropriate here. As
Kumar mentioned, only CONFIG_BOOKE is needed.

* [PATCH v4] Make instruction dumping work in real mode.
From: Scott Wood @ 2007-09-27 18:38 UTC (permalink / raw)
To: paulus; +Cc: linuxppc-dev
On non-book-E-or-4xx, exceptions execute in real mode. If a fault happens
that leads to a register dump, the kernel currently prints XXXXXXXX because
it doesn't realize that PC is a physical address.
This patch checks the state of the IMMU, and if necessary converts PC into a
virtual address.

OK, just CONFIG_BOOKE this time. :-P

I think in_atomic() is what you want.

well, try to get rid of padding first.
are you sure about -e? please try
mkfs.jffs2 -e 128 -d ./myimage -b -o out.jffs2 instead.
