* [PATCH] powerpc: Add xmon function to dump 44x TLB
From: Benjamin Herrenschmidt @ 2007-11-16 7:23 UTC (permalink / raw)
To: Josh Boyer; +Cc: linuxppc-dev
This adds a function to xmon to dump the content of the 44x processor
TLB with a little bit of decoding (but not much).
Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

Did that to track down some machine checks I was having while working
on PCI support due to 32/64 bits resource screwage.
Useful to see where a given MMIO virtual address really maps to.

* [RFC/PATCH] powerpc: Fix powerpc 32 bits resource fixup for 64 bits resources
From: Benjamin Herrenschmidt @ 2007-11-16 7:28 UTC (permalink / raw)
To: linuxppc-dev
The 32bits powerpc resource fixup code uses unsigned longs to do the
offseting of resources which overflows on platforms such as 4xx where
resources can be 64 bits.
This fixes it by using resource_size_t instead.
However, the IO stuff does rely on some 32 bits arithmetic, so we hack
by cropping the result of the fixups for IO resources with a 32 bits
mask.
This isn't the prettiest but should work for now until we change the
32 bits PCI code to do IO mappings like 64 bits does, within a reserved
are of the kernel address space.
Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

DO NOT MERGE YET ! This has only been tested with some preliminary PCI
support code I have for Ebony, I haven't yet verified that the masking
stuff works fine on 32 bits machines with multiple busses and negative
offsets.

* [PATCH] e1000: Fix for 32 bits platforms with 64 bits resources
From: Benjamin Herrenschmidt @ 2007-11-16 7:37 UTC (permalink / raw)
To: auke-jan.h.kok; +Cc: netdev, jgarzik, linuxppc-dev
The e1000 driver stores the content of the PCI resources into
unsigned long's before ioremapping. This breaks on 32 bits
platforms that support 64 bits MMIO resources such as ppc 44x.
This fixes it by removing those temporary variables and passing
directly the result of pci_resource_start/len to ioremap.
The side effect is that I removed the assignments to the netdev
fields mem_start, mem_end and base_addr, which are totally useless
for PCI devices.

I'm not sure I like this. It introduces another cpu feature flag,
that we'll soon run out of if it's used to signify version info per
implementation like this.
1) The SET_IVOR could be done from the cpu_setups for 440A instead
(i.e. introduce one).
2) Please just move the machine check handlers out to individual ones
instead of using the generic one. That way you don't need runtime checks
between the two (they don't seem to share much of it as-is anyway).
With the above two changes, you shouldn't need the feature bit any more.

pcibios_free_controller() is now available for both 32 and 64 bits
but the header only declares it for 64 bits. This moves the

Note that first, I'd like to figure out if there are other relevant
differences with 440A ... arch/ppc didn't list any and diff'ing PDFs is
not fun but if people around here know, please speak up

Ok, here's what I came up with:
/*
* The exception table consists 3 32-bit words, the encoding takes
* advantage of the fact that all kernel text addresses on sparc64 are
* in the low 4GB of the 64-bit address space so any location can be
* encoded in 32-bits.
*
* The first word is the address of an instruction that is allowed to
* fault. This is the search key used by search_exception_tables().
*
* The second word is a continuation address in the kernel text.
*
* The third word is an instruction to execute before transferring
* control to the location specified by the second word. Most of
* these instructions are of the form:
*
* mov -EFAULT, %reg
*
* Effectively the trap return TPC is set to the address of the third
* word, and the trap return TNPC is set to the value contained in the
* second word.
*/
struct exception_table_entry {
unsigned int insn, fixup_addr, fixup_insn;
};
And then __put_user_asm() now looks like:
#define __put_user_asm(x,size,addr,ret) \
__asm__ __volatile__( \
"/* Put user asm, inline. */\n" \
"1:\t" "st"#size "a %1, [%2] %%asi\n\t" \
"clr %0\n" \
"2:\n\n\t" \
".section __ex_table\n\t" \
".word 1b, 2b; mov %3, %0\n\t" \
".previous\n\n\t" \
: "=r" (ret) : "r" (x), "r" (__m(addr)), \
"i" (-EFAULT))
The .fixup section is completely eliminated, and the exception
dispatch goes:
regs->tpc = (unsigned long) &entry->fixup_insn;
regs->tnpc = entry->fixup_addr;
I have a full patch implementing this and it passes a
allyesconfig build and link.

Yes, this is a familiar problem, at least for me. :-)

On my machine it hangs after returning from kernel_execve()/do_execve(),
which is called by run_init_process("/sbin/init"). So the problem can be
almost anywhere. The problem appeared first on kernel 2.6.17. 2.6.16
worked fine on my machine.
I'm going to try out git-bisect on these two kernel revisions, now that I
figured out what people mean when they talk about bisecting. :-) I just
have to figure out how to merge my patches with every branch that is
checked out by git-bisect.

Hey, I can understand that customer, I like pinging as well.
And it works for me. Our design is based on ML403.

Yeah, that might work. I'm wondering if either method needs to take
arch/ppc into account, as the cputable is shared.

Anton pinged me about cleaning that up a couple months ago. I have a
half-baked patch for it somewhere, but I agree having 4xx set a ppc_md
specific handler would be a good idea.

* 85xx software reset problems from paulus.git
From: robert lazarski @ 2007-11-16 15:00 UTC (permalink / raw)
To: linuxppc-embedded
Hi all, on my custom 85xx board I can't do a soft reset. I'm using
u-boot 1.3rc3 that has the latest cpu/mpc85xx/cpu.c patch to fix some
type of reset problem. When I press the software reset button on my
board after my nfs kernel panic, I get this:
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(2,0)

Please define "software reset button" in your case. :-)
I consider a "button" clearly as hardware.
In my case (my button) asserts the HRESET# CPU pin low.
As far as I understood the details (not verified again):
To trigger a hard reset via software, the CPU (8540 at least)
should assert the HRESET_REQ# (Pin AG20) low (which needs
to be triggered in software, somehow).
Some external glue logic should then issue the HRESET#
(pin AH16) low to reset the CPU (hard, Power On Reset).
The SRESET# (pin AF20) is the soft reset input, causes
an mcp assertion to the core.... (RTFM)
So, the detailed explanation seems to be implementation
specific (if HRESET_REQ# can get triggered and if HRESET_REQ#
assertion is glued to assert HRESET# from the HW guys).

Not really. I just can confirm that the a $shutdown -r now doesn't
reboot my board anymore whereas 2.6.21-rc4 did.
IIRC, I've seen a patch which changed some instructions in some reboot()
function some time ago.
(Please note, I'm using the mpc8540_ads which might be slightly different
from the *_cds.)

Clemens Koller

Hello folks,
The following patch sequence is intended to add support for the Emerson
Katana Qp ATCA board based on MPC7448 CPU and Marvell 64460 chipset.
The patches are incremental to minor mv64x60 code fixups sent by
Mark A. Greer on 11/08/07.
Thanks,
Andrei.

Erm actually, that last one would give you a compiler warning ("function
defined but not used"), unless you convert the point where it is used to
a plain "if" too -- probably not worth it until we have 32-bit
multiplatform
support :-)

* [PATCH 2/5] PowerPC 74xx: Minor updates to MV64x60 boot code
From: Andrei Dolnikov @ 2007-11-16 16:18 UTC (permalink / raw)
To: linuxppc-dev
This patch adds new functionality to MV64x60 boot code. The changes are required
to access DevCS windows registers and set PCI bus and devfn numbers for MV644x60
PCI/PCI-X interfaces.

* [POWERPC] [RFC] Fix 8xx tlbie definition
From: Josh Boyer @ 2007-11-16 17:28 UTC (permalink / raw)
To: vitb, benh; +Cc: linuxppc-dev
Git commit e701d269aa28996f3502780951fe1b12d5d66b49 introduced an incorrect
definition for _tlbie on PowerPC 8xx platforms. Only the address should be
passed to the function. This patch corrects the definition of _tlbie and the
related tlb flushing functions for 8xx.
