There's basically only two cases: if we have a builtin flat tree, we
pass that and NULL in r5; if we don't, and we have OF, we pass NULL in
r3 and the OF entry point in r5. I think that could be handled in
main.c.
We also lost the "enforce minimum address only for 64-bit" thing in
the translation, too.
I believe that just patch 1/6 on its own won't give us a working
zImage, so we'll have to split up the changes differently when it
comes time to check this stuff in to git.

There is no support for any of this in the current PowerPC 32 bits
kernel. It's possible to add it, though, but it's not alrady there.
There are two main issues:
- One is to enable support for sparse memory maps and add the necessary
support to the low mm code. Not terribly hard (see how it's done for 64
bits)
- A more annoying one is support for DMA since a lot of devices cannot
DMA above 32 bits. A lot of 'sane' platforms that provide more memory
than can be DMA'ed in 32 bits also provide an IOMMU that does page
translation of incoming DMAs. This isn't your case however, thus you
would have to implement some of the alternate solutions used on x86_64
(Intel 64 bits platforms also lack an iommu). This essentially consist
of defining a ZONE_DMA32 and possibly also using swiotlb to do bounce
buffering for drivers that don't deal with ZONE_DMA32 yet.

* [PATCH 4/4]: PowerPC: EEH: support MMIO enable recovery step
From: Linas Vepstas @ 2006-09-15 23:58 UTC (permalink / raw)
To: Paul Mackerras; +Cc: linuxppc-dev, linux-kernel, anton
In-Reply-To: <20060915235025.GQ29167@austin.ibm.com>
Update to te PowerPC PCI error recovery code.
Add code to enable MMIO if a device driver reports
that it is capable of recovering on its own. One
anticipated use of this having a device driver
enable MMIO so that it can take a register dump,
which might then be followed by the device driver
requesting a full reset.

To: Paul Mackerras; +Cc: linuxppc-dev, linux-kernel, anton
Paul,
Please apply and submit upstream. These patches are not urgent,
and are mostly harmless.
The following set of patches add support for the MMIO-enabled
EEH recovery path, that is, for the path through te PCI error
recovery code where the device driver claims it can recover
on its own, and just wants MMIO enabled.
Actually, the first two patches are misc EEH cleanup,
the last two implement this function.

You probably want to enable the CONFIG_ARCH_SPARSEMEM_ENABLE option, which
is currently dependant on CONFIG_PPC64.
Look in the early_init_dt_scan_memory function (arch/powerpc/kernel/prom.c)
for how to layout the "memory" nodes in your device tree.

There is no set date or kernel release where this will be done. In

* Discontiguous Memory
From: jbahr @ 2006-09-15 20:22 UTC (permalink / raw)
To: linuxppc-dev
We have a client building a PPC8548-based product who insists that we
allocate DRAM real address space in two large chunks at 0-2GB and 4-6GB in
the 36-bit address space. It doesn't look like U-Boot's bd_info structure
allows for that, and it doesn't look like the Linux init routines (which
accesses the passed table) knows how to handle discontiguous memory either
(as opposed to X86 Linux, which can accept an E820 table).
It looks like Linux cleans out the TLB's pretty quickly, so it wouldn't know
the VA-to-RA mapping.
I've seen papers on some PPC Linuxes that handle large discontiguous real
DRAM memory spaces, but it doesn't look like the Linux in ELDK does. Is
that correct?
This is just the start of a headache between the architects and we poor
implementers. It's not clear to us that, even with ATMU support, how normal
drivers are going to know how to create real addresses for buffers and such
to use when programming DMA controllers or external PCI devices.
Are this really a problem or is there kernel provision for the PPC for
discontiguous real memory DRAM space?
Any comments would be VERY appreciated.
Regards,
J

We've used the Macraigor Wiggler on an 8548 board. It's MUCH slower than the
BDI, but it does work. We've also tried their Raven and USB products (about
$750) but they didn't work or were no faster than the Wriggler.

* Kernel module insertion issue with kernel 2.6.15
From: Prakash Jain @ 2006-09-15 19:56 UTC (permalink / raw)
To: Linux PPC List
Hi,
I am relatively new to this list/area, not sure if this is right forum
for my query (please point me to right list in that case).
I am porting my software from 2.4 kernel to 2.6.15 on a board similar to
ppc 82xx sandpoint architecture. I am able to make the board functional
except the following issue. One of my kernel module (inserted thru
insmod) takes almost 6-7 minutes to load with 2.6 kernel while it used
to take only few seconds with 2.4 kernel. Yet, after the long wait
module is inserted correctly with 2.6 kernel as board software works
fine after that. When I halt the processor (using BDI2000) during the
long wait, it always halts in function get_plt_size() in kernel's
arch/ppc/kernel/module.c. Single stepping does not take to any error or
suspicious place. Looks like it is going thru the long for() loop in the
function. Only suspicion I got is while compiling the module, it
generates tons of undefined symbols. I ignored them as it was a third
party software and module inserts correctly at the end.
Can someone give few pointers on what could be the reasons and where to
look to resolve this? Will appreciate your time,
Thanks,
Prakash

That does seem to be the case. The printer is back up, apparently after a
"cups-lpr" update. Sorry about the noise, although the strace thing still
bothers me. Not enough to pursue it any more, though ;)

* Kernel Blocked

To: linuxppc-embedded
Hi All,
First, if anyone wants to use linux 2.6.18-rc2-g73a589b5 with ppc, he
should patch inflate.c from linux 2.6.18-rc7 to fix Uncompressing
failure problem. But new problem is: when relocate and gunzip functions
are finished, and 'Now booting the kernel' is shown, the system is
halted. My bootloader is working fine with linux 2.6.13, could anyone
tell me what the next function executes and how to check this kind of
problem, thanks.

* [PATCH] PPC: Fix xmon stack frame address in backtrace
From: Josh Boyer @ 2006-09-15 19:53 UTC (permalink / raw)
To: paulus; +Cc: linuxppc-dev
The stack frame address was being printed incorrectly in the backtrace
option of XMON on PPC. This patch fixes it to print the actual stack
address instead of the address of the local variable that contains it.
Patch is against current powerpc.git tree.

Hi Keith,
I know that on the surface it seems like a simple thing. Some of our
parts are big, yet some are small. We are always getting pressure to
make our IP as small as possible.
Though, this may be something we can revisit again, for now this
information just isn't going to be available.
Perhaps the problem can be solved in a different way.

John,
I thinking in terms of something like a 32 bit register
(i.e. like a processor's PVR register) that has a hard-coded magic
number
which a driver can read and decode to determine driver compatibility.
That does not sound resource-intensive given the size FPGAs we are
talking
about. Probably don't even need 32 bits.

Yes, I do not get full code coverage, which would be the ideal.
However, I do run defconfig, allmodconfig, allyesconfig and allnoconfig
and have found issues doing this. There is value in running for a
few representative ppc architectures, which I do. That is why 'defconfig'
is (was) handy for me.
I additionally compile other architectures such as i386, ia64, x86_64,
arm, sparc64. People can submit their kernel patches to see how
their code compiles, and usually this is more platforms than they would
do at home.:)

Yes. Whether you pass the NULL or not hinges on whether its flat tree

* [PATCH 7/7] POWERPC: Bring the fs_no calculation to the relevant SoC enumeration
From: Vitaly Bordug @ 2006-09-15 17:39 UTC (permalink / raw)
To: Paul Mackerras; +Cc: linuxppc-dev
In-Reply-To: <20060915213751.128e85f3@localhost.localdomain>
The fs_no mean used to be fs_enet driver driven, hence it was an
enumeration across all the possible fs_enet "users" in the SoC. Now, with
QE on the pipeline, and to make DTS descriptions more clear, fs_no features
relevant SoC part number, with additional field to describe the SoC type.
Another reason for that is now not only fs_enet is going to utilize those
stuff. There might be UART, HLDC, and even USB, so to prevent confusion and
be ready for upcoming OF_device transfer, fs_enet and cpm_uart drivers were
updated in that concern, as well as the relevant DTS.

* [PATCH 5/7] POWERPC: Get rid of remapping the whole immr
From: Vitaly Bordug @ 2006-09-15 17:39 UTC (permalink / raw)
To: Paul Mackerras; +Cc: linuxppc-dev
In-Reply-To: <20060915213751.128e85f3@localhost.localdomain>
The stuff below cleans up the code attempting to remap the whole cpm2_immr
early, as well as places happily assuming that fact. This is more like the 2.4
legacy stuff, and is at least confusing and unclear now.
To keep the world comfortable, a new mechanism is introduced: before accessing
specific immr register/register set, one needs to map it, using cpm2_map(<reg>),
for instance, access to CPM command register will look like
volatile cpm_cpm2_t *cp = cpm2_map(im_cpm);
keeping the code clear, yet without "already defined somewhere" cpm2_immr.
So far, unmapping code is not implemented, but it's not a big deal to add it,
if the whole idea makes sense.

* [PATCH 4/7] POWERPC: Add support for the mpc8560 eval board
From: Vitaly Bordug @ 2006-09-15 17:39 UTC (permalink / raw)
To: Paul Mackerras; +Cc: linuxppc-dev
In-Reply-To: <20060915213751.128e85f3@localhost.localdomain>
This makes the 8560 evaluation board fully supported under arch/powerpc,
as the first board with CPM2 SoC peripherals. The brand new devicetree
nodes are introduced (intending to be a subset of the QuiccEngine-equipped
models, with dts sources placed into the kernel according to the new convention.
Assuming all the preceding stuff applied (PAL+fs_enet related+ CPM_UART
update), the both TSEC eth ,FCC Eths, and both SCC UARTs are
working. The relevant drivers are still capable to drive users in ppc,
which was verified with 8272ADS (SCC uart+FCC eth).
This is also verified on mpc8540 and actually make it work (PCI stuff
working as well)
