This I think is fine as ibm,uic. Unless AMCC actually changed the UIC
to have differences, it was found on the IBM boards first :)

You can probably just omit the child EBC nodes for now. Adding them

Why did you rename the fixup_memsize function? Could you add that to
the changelog, and perhaps a bit about adding the SDRAM0_{READ,WRITE}
macros.

You felt like duplicating this? It was added in the previous patch. :)

* dtc: Reinstate full old-style reference-to-path for v0 dts files
From: David Gibson @ 2007-12-07 3:38 UTC (permalink / raw)
To: Jon Loeliger; +Cc: linuxppc-dev
Commit 7c44c2f9cb1cc2df7aacd13decfc4e64b73d1730 broke backwards
compatibility more badly than I realised. Contrary to what I thought
there are in-kernel, in-use dts files which relied on
references-to-path with paths including a comma, which no longer
compile after that commit.
So, this patch reinstates full support for bare references-to-path in
dts-v0 input. This means there will be some rather surprising lexical
corner cases when using path-expanded references in v0 files. But,
since path-expanded references are new, v0 files shouldn't typically
be using them anyway. If the corner cases cause a problem, you can
always convert to dts-v1 which handles the lexical issues here more
nicely.

Even so, I don't think too safe :) It might technically work,
but it could break more easily.
So even if you find places where list_head is the first member of
a structure, it would be nice to explicitly use the list_head member
and avoid casts IMO.
Thanks,
Nick

I know, but I'd prefer that there was a broken range of dtc versions
than a broken range of kernel versions.

* dtc: Make dtc-checfails.sh script catch deaths-by-signal
From: David Gibson @ 2007-12-07 4:37 UTC (permalink / raw)
To: Jon Loeliger; +Cc: linuxppc-dev
Since commit 5ba0086bfd0fa6ab25f7ce1870417301a26c104f, the
dtc-checkfails.sh script does not check the return code from dtc.
That's reasonable, since depending on the checks we're testing, dtc
could either complete succesfully or return an error.
However, it's never right for dtc to SEGV or otherwise be killed by a
signal. So the script should catch that, and fail the testcase if it
happens. This patch implements this behaviour.

This is exactly what I think. Those patches actually fix no bugs, but
avoid this kind of technically and currently correct casting.

* [PATCH 3/3] [POWERPC] iSeries: merge vpdinfo.c intp pci.c
From: Stephen Rothwell @ 2007-12-07 5:10 UTC (permalink / raw)
To: ppc-dev
In-Reply-To: <20071206180045.0eb1db98.sfr@canb.auug.org.au>
There was only one global function in vpdinfo.c and it was only called
from pci.c, so merge them and make the function static.

* [RFC][POWERPC] Provide a way to protect 4k subpages when using 64k pages
From: Paul Mackerras @ 2007-12-07 6:09 UTC (permalink / raw)
To: linuxppc-dev, linux-kernel
Using 64k pages on 64-bit PowerPC systems makes life difficult for
emulators that are trying to emulate an ISA, such as x86, which use a
smaller page size, since the emulator can no longer use the MMU and
the normal system calls for controlling page protections. Of course,
the emulator can emulate the MMU by checking and possibly remapping
the address for each memory access in software, but that is pretty
slow.
This patch provides a facility for such programs to control the access
permissions on individual 4k sub-pages of a 64k page. The idea is
that the emulator supplies an array of protection masks to apply to a
specified range of virtual addresses. These masks are applied at the
level where hardware PTEs are inserted into the hardware page table
based on the Linux PTEs, so the Linux PTEs are not affected. Note
that this new mechanism does not allow any access that would otherwise
be prohibited; it can only prohibit accesses that would otherwise be
allowed. This new facility is only available on 64-bit PowerPC and
only when the kernel is configured for 64k pages.
The masks are supplied using a new subpage_prot system call, which
takes a starting virtual address and length, and a pointer to an array
of protection masks in memory. The array has a 32-bit word per 64k
page to be protected; each 32-bit word consists of 16 2-bit fields,
for which 0 allows any access (that is otherwise allowed), 1 prevents
write accesses, and 2 or 3 prevent any access.
Implicit in this is that the regions of the address space that are
protected are switched to use 4k hardware pages rather than 64k
hardware pages (on machines with hardware 64k page support). In fact
the whole process is switched to use 4k hardware pages when the
subpage_prot system call is used, but this could be improved in future
to switch only the affected segments.
I have re-purposed the ioperm system call for this. The old ioperm
system call never did anything (except return an ENOSYS error) and in
fact never could have actually been useful for anything on the PowerPC
architecture, so nothing ever used it.

How about this: We change the compatible node to "plb-pciex-440spe"
(without "A" and "B) and make a PVR runtime detection in the 4xx-pci driver.
What do you think? Should I prepare a patch for this?

Ok. Thanks.

* dtc: Allow gcc format warnings for check_msg()

check_msg() takes printf() like arguments, so tell gcc to produce
printf() like warnings for it.

I think it needs some more inspection. The msleep in there is only called
for hcalls that return H_IS_LONG_BUSY(). In theory, you can call
ehca_plpar_hcall_norets() from inside an interrupt handler if the
hcall in question never returns long busy.

No problems on Katmai (440SPe) and Kilauea (405EX) so far. Apart from DEBUG
still enabled in patch 8/10 as Olof already pointed out.
