* [RFC 08/10] um: dyn/uml.lds.S cleanup - use PAGE_SIZE macro
From: gorcunov @ 2008-02-27 20:58 UTC (permalink / raw)
To: rth, chris, jdike, linuxppc-dev, paulus, dhowells, zippel, geert,

Cc: gorcunov, sam
In-Reply-To: <20080227205831.150784453@gmail.com>
This patch includes page.h header into liker scripts that
allow us to use PAGE_SIZE macro instead of numeric constant.
To be able to include page.h into linker scripts page.h is
needed for some modification - i.e. we need to use __ASSEMBLY__
and _AC macro

Ok. Now it's fixed.
The major revision number of some ppc cores by Freescale is placed in
the configuration field instead of the major revision field. The patch
corrects the behaviour for those 74xx cores.

Downloading isn't changed at all by splitting it out to it's own repo.

It seems the real crux of your issue is that you want distros to
provide a libfdt package. That can be done by creating a subpackage
off of the dtc package. The harder part for certain distros will be
either convincing them to allow the static libfdt to exist, or creating
a shared library for it instead.

Works just fine with the Apple UniNorth controller in my powerbook in cursory
testing. Tested with multiple sbp2 hard disks, plugging and unplugging,
mounting and unmounting, etc.

Forgot to check that it survived bus resets. Will try to double-check that
tonight. I don't have any other ppc systems w/firewire controllers handy at
the moment to try other controllers, but can probably manage to get one set
up soon...

* [dtc] breaking out libfdt from dtc so other progs can use it
From: Jerone Young @ 2008-02-27 19:40 UTC (permalink / raw)
To: linuxppc-dev
Currently the dtc source code has libfdt integrated in it. This seems to
have become place for upstream libfdt changes. Now we all know everyone
(linux kernel, cuboot) also have their own versions over libfdt. But if
another userspace app wants to use libfdt , it has to copy it from the
dtc source and try to maintain it's own copy.
The question I have is can libfdt be split out from dtc source, and
become it's own thing. This way other userspace apps can easily download
it and link with it?
The reason I ask is I have added dynamic manipulation support of device
trees in memory into qemu for KVM. But the issue is keeping a copy of
libfdt in the KVM userspace repository, which is getting some opposition
(understandably). But this would be much easier if there was a libfdt
repo for the library so that we wouldn't need to keep our own copy.

* patchwork missing patches?
From: Josh Boyer @ 2008-02-27 15:39 UTC (permalink / raw)
To: jk; +Cc: linuxppc-dev
I'm trying to find some patches that went to the list recently in
patchwork and they seem to be missing. Here are a few:
http://ozlabs.org/pipermail/linuxppc-dev/2008-February/052196.html
http://ozlabs.org/pipermail/linuxppc-dev/2008-February/052164.html
http://ozlabs.org/pipermail/linuxppc-dev/2008-February/052129.html
http://ozlabs.org/pipermail/linuxppc-dev/2008-February/052050.html
There might be more. Maybe I'm just blind, but I can't find them at
all in patchwork.

Thanks, looks much better. I'll send this to Paul later today.
