Hi Leon,=20
=20
interrupt-map-mask is missing for pcie@ffe0a000 node. Please see my commen=
t there...=20
pcie@ffe0a000 node deals with mini-PCIe.=20
one more thing, can you please tell P1020Si version. It will be there on u-=
boot log.

* [PATCH] powerpc/e500mc: Remove CPU_FTR_MAYBE_CAN_NAP/CPU_FTR_MAYBE_CAN_DOZE
From: Kumar Gala @ 2011-04-08 9:40 UTC (permalink / raw)
To: linuxppc-dev; +Cc: Scott Wood
From: Scott Wood <scottwood@freescale.com>
e500mc does not support the HID0/MSR mechanism that is used by e500_idle
(and there are also issues with waking on certain types of interrupts).
Further, even if napping is never actually enabled, just having
CPU_FTR_CAN_NAP will cause machine_init() to overwrite the board's supplied
ppc_md.power_save().
We drop CPU_FTR_MAYBE_CAN_DOZE becuase we should use 'wait' instead on
e500mc.

* [PATCH v3] powerpc/book3e: Fix CPU feature handling on 64-bit e5500
From: Kumar Gala @ 2011-04-08 9:40 UTC (permalink / raw)
To: linuxppc-dev
The CPU_FTRS_POSSIBLE and CPU_FTRS_ALWAYS defines did not encompass
e5500 CPU features when built for 64-bit. This causes issues with
cpu_has_feature() as it utilizes the POSSIBLE & ALWAYS defines as part
of its check.
Create a unique CPU_FTRS_E5500 (as its different from CPU_FTRS_E500MC),
created a new group for 64-bit Book3e based CPUs and add CPU_FTRS_E5500
to that group.

* hotplug support on 85xx smp ?
From: Kumar Gala @ 2011-04-08 9:25 UTC (permalink / raw)
To: Benjamin Herrenschmidt; +Cc: Linuxppc-dev list
Ben,
If looks like SUSPEND support requires CPU hotplug (forces =
CONFIG_HOTPLUG_CPU). This is causing current 2.6.39-rc2 to break for =
85xx-smp. Are you willing to take patches that add cpu hotplug support =
for 85xx/e500 for 2.6.39 to fix this?

I compiled the new device tree binary, the dump is below(*) and booted
the P1020RDB from that.
I verified using an oscilloscope that IRQ0 indeed remains high.
However, no interrupt seems to come in from the sata_sil24 driver, see
boot log (**).

The above is incorrect modulo arithmetic.
It is probably intended to do:
s32 delta =3D val - prev;
return delta < 0 ? 0 : delta;
which will just ignore the fact that some counts are rolled back.
More accurate would be:
static u64 val64;
u32 val =3D read_perf_count();
s32 delta =3D val - val_64;
if (delta < 0)
return;
val64 +=3D delta;
Which will not double count for rolled back events.
(The low bits of val64 should always match the actual counter.)

Do you have these for P1020RDB as well? I found a P1020RDB board that

* [PATCH 3/3] powerpc: Use MSR_64BIT in sstep.c, fix kprobes on BOOK3E
From: Michael Ellerman @ 2011-04-08 7:56 UTC (permalink / raw)
To: linuxppc-dev; +Cc: Paul Mackerras
In-Reply-To: <ca7cc2a36bbf492c11cd98d3d1dea0835731c75f.1302249358.git.michael@ellerman.id.au>
We check MSR_SF a lot in sstep.c, to decide if we need to emulate the
truncation of values when running in 32-bit mode. Factor out that code
into a helper, and convert it and the other uses to use MSR_64BIT.
This fixes a bug on BOOK3E where kprobes would end up returning to a
32-bit address, because regs->nip was truncated, because (msr & MSR_SF)
was false.

* [PATCH 2/3] powerpc: Use MSR_64BIT in places
From: Michael Ellerman @ 2011-04-08 7:56 UTC (permalink / raw)
To: linuxppc-dev; +Cc: Paul Mackerras
In-Reply-To: <ca7cc2a36bbf492c11cd98d3d1dea0835731c75f.1302249358.git.michael@ellerman.id.au>
Use the new MSR_64BIT in a few places. Some of these are already ifdef'ed
for BOOKE vs BOOKS, but it's still clearer, MSR_SF does not immediately
parse as "MSR bit for 64bit".

From: Michael Ellerman @ 2011-04-08 7:56 UTC (permalink / raw)
To: linuxppc-dev; +Cc: Paul Mackerras
The MSR bit which indicates 64-bit-ness is different between server and
booke, so add a #define which gives you the right mask regardless.

From: Anton Blanchard @ 2011-04-08 7:44 UTC (permalink / raw)
To: benh, paulus; +Cc: linuxppc-dev
We currently enable interrupts before the dispatch log for the boot
cpu is setup. If a timer interrupt comes in early enough we oops in
scan_dispatch_log:
Unable to handle kernel paging request for data at address 0x00000010
...

.account_system_vtime+0xa0/0x220
.irq_enter+0x88/0xc0

The patch below adds a check to scan_dispatch_log to ensure the
dispatch log has been allocated.

In __access_remote_vm() we need to check that we have found the right
vma, not the following vma, before we try to access it. Otherwise we
might call the vma's access routine with an address which does not
fall inside the vma.

The calculation of the size for the exception save area of the TLB

Rework it to make it a bit clearer, and also correct. We want 3 save

Ah good point, if git hadn't done such a good job of merging it I would
have noticed :)
I'll send a new version with a corrected changelog.

The access implementations I've looked at check len, but I guess it
could be truncated on the way in. But maybe that's being paranoid, I
dunno.

Hello Leon,
Yes you are right, PCIe leagacy interrupt is shared with IRQ0. For Atheros=

For legacy interrupt to work IDSEL values are required.. please find the co=
rrect IDSEL values for pci0/1.
pci0: pcie@ffe09000 {

Thing what happens without the do { ... } while(0) if you have code
that looks like:
if (enable_debug)
MY_ASSERT(foo);

* [PATCH] lib: Consolidate DEBUG_PER_CPU_MAPS
From: Stephen Boyd @ 2011-04-07 19:20 UTC (permalink / raw)
To: Andrew Morton; +Cc: linux-arch, x86, linuxppc-dev, linux-kernel
DEBUG_PER_CPU_MAPS is used in lib/cpumask.c as well as in
inlcude/linux/cpumask.h and thus it has outgrown its use within x86
and powerpc alone. Any arch with SMP support may want to get some
more debugging, so make this option generic.

I don't know what tree to send this through, so I'm sending it to
