Never mind, if we do add pwr mgmt it looks like all we need to know is
what SerDes is associated with the device.

The latest u-boot supports the serdes initialization for 837x.
So, it can be dropped from kernel for now.

I'm ok for it to be taken care of in u-boot for now. However, if we
later plan to add power management support to this block. We probably
have to do it in kernel.

Upon further review of all this I don't think this belongs in the

* [PATCH] sys_indirect kernel implementation for PowerPC
From: Paul Mackerras @ 2007-11-21 3:08 UTC (permalink / raw)
To: Ulrich Drepper, linuxppc-dev
This implements sys_indirect for 32-bit and 64-bit powerpc machines,
including a 32-bit compatibility implementation for 64-bit powerpc.
I decided to use assembly language for call_syscall because on 64-bit
powerpc the system call table has the addresses of the function text
rather than pointers to function descriptors; hence the system call
functions can't be called from C via the system call table.
Signed-off-by: Paul Mackerras <paulus@samba.org>

This patch applies on top of Ulrich Drepper's series adding the
generic and x86-specific code for sys_indirect.

From: Linas Vepstas @ 2007-11-21 2:09 UTC (permalink / raw)
To: Paul Mackerras; +Cc: linuxppc-dev, strosake
The pseries hypervisor attempts to detect and prevent an
infinite loop of kernel crashes and auto-reboots. It does
so by refusing to auto-reboot unless we indicate that the
current boot was sucessful. So, indicate success late in
the boot sequence.

Sigh. This is a side-effect of the patch I sent yesterday.
Its supposed to simplify the management large numbers of

* dtc: Add valgrind support to testsuite
From: David Gibson @ 2007-11-21 0:56 UTC (permalink / raw)
To: Jon Loeliger; +Cc: linuxppc-dev
This patch adds some options to the run_tests.sh script allowing it to
run all the testcases under valgrind to check for pointer corruption
bugs and memory leaks. Invoking "make checkm" will run the testsuite
with valgrind.
It include a mechanism for specifying valgrind errors to be suppressed
on a per-testcase basis, and adds a couple of such suppression files
for the mangle-layout and open_pack testcases which dump for use by
other testcases a buffer which may contain uninitialized sections. We
use suppressions rather than initializing the buffer so that valgrind
will catch any internal access s to the uninitialized data, which
would be a bug.
The patch also fixes one genuine bug caught by valgrind -
_packblocks() in fdt_rw.c was using memcpy() where it should have been
using memmove().
At present the valgrinding won't do anything useful for testcases
invoked via a shell script - which includes all the dtc testcases. I
plan to fix that later.

* dtc: Remove some redundant testcases
From: David Gibson @ 2007-11-21 0:29 UTC (permalink / raw)
To: Jon Loeliger; +Cc: linuxppc-dev
This patch removes a number of testcases from the testsuite that are
extremely unlikely to find any bugs that won't be found by the other
tests. This speeds up the testsuite.
- Both loops across the various tree block layouts run the
tree1_tests on the basic mangled tree. This is completely redundant,
so remove the second copy. This removes 456 testcases.
- We currently run tree1_tests on various trees manipulated by
move_and_save. We replace those with just a dtbs_equal_ordered test
to check that the manipulated tree is equal to the original. What
we're testing here is that fdt_move() operates correctly - it's very
unlikely it would succeed well enough for the ordered_equal test to
succeed, but the tree1_tests would fail on the result. This removes
162 testcases.
- Currently we re-ordered with mangle-layout both the basic
test_tree1.dtb and sw_tree1.test.dtb. Since we've already checked
that these dtbs are equivalent with dtbs_ordered_equal, it's very
unlikely that the tests would fail on one but not the other.
Therefore reduce this to only using test_tree1.dtb. This removes 828
testcases.

BTW, you may want to send the patches to linuxppc-dev rather than

Generating patches with "git-format-patch -M" isn't the same as pushing
directly...

I am not asking you to stop sending patches.
I'm asking you to generate your patches with git.
Git's patch format, send through mail, handles
the execute permissions.

Right. I'm just asking for it to be used. :-)

* mmap on PPC removes file refcount?
From: Dave Jiang @ 2007-11-20 21:35 UTC (permalink / raw)
To: linuxppc-dev
It seems the mmap() userland call on PPC causes the kernel to lose the ref
count for the mount point. This is what I did on a prpmc2800 board (74xx) with
latest powerpc.git tree (but also seem to happen on 8548 as well).
I mounted an IDE partition. The userland test app opens a file on the mounted
partition and sits in a sleep loop while holding the file open. I call umount
on the partition and I get "device is busy" which is suppose to happen.
However, after the test app calls mmap on the file id for the opened file, I
can successfully umount even though it should still say "device is busy". This
does not happen on x86 so I'm assuming something is going on with just PPC.
So using lsof I can list the opened files on a particular partition. When the
file is opened, it lists 1 entry. When mmaped, on x86 it would list 2 entries,
but on ppc it lists nothing. Not only did the mmaped entry not show up, the
entry caused by open disappeared as well. Also, I put a printk in do_umount()
to see what the refcount is. On x86, it would be 3 and thus causes device busy.
On PPC it is 3 when the file is openend, however if mmap is called, the
refcount becomes 2 and thus umount proceeds. It's almost as if the mmap call
wiped out the opened file entry and decremented the mount count as well.

Well, yes. But, IMO, every time anyone other that you or I has
commented on one of these patches as it goes past counts as an
occasion when it's better that I've been using patches, rather than
pushing to you direct with git.

Actually, that should be possible with mails too, it's just that I
