Hi,
as you've suggested, I've added a printout inside fsl_pcie_check_link()

enabled.
thank you,
Davide

Hi,
I am testing 3.6.0-rc7 with this v9 patchset plus more recent fixes [1],[2],[3]
Running in a guest (qemu+seabios from [4]).
CONFIG_SLAB=y
CONFIG_DEBUG_SLAB=y
After succesfull hot-add and online, I am doing a hot-remove with "echo 1 > /sys/bus/acpi/devices/PNP/eject"
When I do the OSPM-eject, I often get slab corruption in "acpi-state" cache, or in other caches

Is this a known issue? If yes, can you point me to any relevant patches?
When I do an SCI(hardware) eject, I have not seen corruptions. The acpi driver is
evaluating fewer objects in this path I think, but I don't see why corruption can't
happen here as well.
I have seen similar problems with CONFIG_SLUB (I did not have debug_options
there but I can also provide those if helpful)

* [PATCH] rapidio/rionet: fix multicast packet transmit logic
From: Alexandre Bounine @ 2012-09-26 19:14 UTC (permalink / raw)
To: Andrew Morton, linux-kernel, linuxppc-dev
Cc: Alexandre Bounine, David S. Miller, netdev
Fix multicast packet transmit logic to account for repetitive transmission
of single skb:
- correct check for available buffers (this bug may produce NULL pointer
crash dump in case of heavy traffic);
- update skb user count (incorrect user counter causes a warning dump from
net_tx_action routine during multicast transfers in systems with three or
more rionet participants).

It's a runtime detection thing, CONFIG is not useful.

Look at arch/powerpc/platforms/powermac/feature.c, fine the machine
table and add the flag to your entry: PMAC_MB_CAN_SLEEP
Makes sure you have no video driver loaded at all, nor AGP either.
Finally, it might not work ... hard to tell, there may be other things
needed.

This problem let me recall what I reported several months ago.
https://lkml.org/lkml/2012/6/27/631
At that time, I thought it is caused by uses_mmap field in record sub
command which
added by commit d1cb9f(perf target: Add uses_mmap field).
In that testcase, it's fine to use stat sub command, but failed with
record sub command.
As Namhyung metioned in that thread, [perf record xxx] use
per-task-per-cpu for fix
scalability issues.

So its odd that scanning of the second bus didn't report any devices. =
Do you have code that implements ppc_md.pci_exclude_device ?
If so, what does it do?
You might also want to put some code in the indirect PCI ops =
(indirect.c) to see what actual values you are getting from various =
indirect_read_config() calls.

I have already sent the log.
Do you have any comment on it?

I can't reproduce this problem. Can you provide the following information:
1. config file
2. qemu's command line
You said you did OSPM-eject. Do you mean write 1 to /sys/bus/acpi/devices/PNP0C80:XX/eject?
Thanks

* [PATCH 2/3] edac/85xx: PCI/PCIe error interrupt edac support
From: Chunhe Lan @ 2012-09-27 19:02 UTC (permalink / raw)
To: linuxppc-dev; +Cc: kumar.gala, Chunhe Lan
In-Reply-To: <1348772523-17587-1-git-send-email-Chunhe.Lan@freescale.com>
Adding pcie error interrupt edac support for mpc85xx and p4080.
mpc85xx uses the legacy interrupt report mechanism - the error
interrupts are reported directly to mpic. While, p4080 attaches
the most of error interrupts to interrupt 0. And report error
interrupts to mpic via interrupt 0. This patch can handle both
of them.

* [PATCH 3/3] edac/85xx: Enable the EDAC PCI err driver by device_initcall
From: Chunhe Lan @ 2012-09-27 19:02 UTC (permalink / raw)
To: linuxppc-dev; +Cc: kumar.gala, Chunhe Lan
In-Reply-To: <1348772523-17587-1-git-send-email-Chunhe.Lan@freescale.com>
Original process of call:
The mpc85xx_pci_err_probe function completes to been registered
and enabled of EDAC PCI err driver at the latter time stage of
kernel boot in the mpc85xx_edac.c.
Current process of call:
The mpc85xx_pci_err_probe function completes to been registered
and enabled of EDAC PCI err driver at the first time stage of
kernel boot in the fsl_pci.c.
So in this case the following error messages appear in the boot log:
PCI: Probing PCI hardware
pci 0000:00:00.0: ignoring class b20 (doesn't match header type 01)
PCIE error(s) detected
PCIE ERR_DR register: 0x00020000
PCIE ERR_CAP_STAT register: 0x80000001
PCIE ERR_CAP_R0 register: 0x00000800
PCIE ERR_CAP_R1 register: 0x00000000
PCIE ERR_CAP_R2 register: 0x00000000
PCIE ERR_CAP_R3 register: 0x00000000
Because the EDAC PCI err driver is registered and enabled earlier than
original point of call. But at this point of time, PCI hardware is not
probed and initialized, and it is in unknowable state.
So, move enable function into mpc85xx_pci_err_en which is called at the
middle time stage of kernel boot and after PCI hardware is probed and
initialized by device_initcall in the fsl_pci.c.

* [PATCH 1/3] edac: Use ccsr_pci structure instead of hardcoded define
From: Chunhe Lan @ 2012-09-27 19:02 UTC (permalink / raw)
To: linuxppc-dev; +Cc: kumar.gala, Chunhe Lan
There are some differences of register offset and definition between
pci and pcie error management registers. While, some other pci/pcie
error management registers are nearly the same.
To merge pci and pcie edac code into one, it is easier to use ccsr_pci
structure than the hardcoded define. So remove the hardcoded define and
add pci/pcie error management register in ccsr_pci structure.

yes.
example qemu command line with one dimm:
"/opt/qemu-kvm-memhp/bin/qemu-system-x86_64 -bios
/opt/extra/vliaskov/devel/seabios-upstream/out/bios.bin -enable-kvm -M pc -smp
4,maxcpus=8 -cpu host -m 2048 -drive file=/opt/extra/debian-template.raw,if=none,id=drive-virtio-disk0,format=raw
-device virtio-blk-pci,bus=pci.0,drive=drive-virtio-disk0,id=virtio-disk0,bootindex=1
-vga cirrus -netdev type=tap,id=guest0,vhost=on -device virtio-net-pci,netdev=guest0
-monitor unix:/tmp/qemu.monitor11,server,nowait -chardev stdio,id=seabios -device
isa-debugcon,iobase=0x402,chardev=seabios
-dimm id=n0,size=512M,node=0"
or last line with 2 numa nodes:
"-dimm id=n0,size=512M,node=0 -dimm id=n1,size=512M,node=1 -numa node,nodeid=0 -numa node,nodeid=1"

To make sure that ppc_md.pci_exclude_device is not implemented, I've=20
put some printouts inside indirect_read_config(): I print various paramete=

What do the values look like in both ATMU registers and io_resource if =

Can you see what bus_no actually gets set to in the case we scan 0001:03 =

If its set to 03, can you try hack it to 1.
