* libfdt: Fix handling of trailing / in fdt_path_offset()
From: David Gibson @ 2007-08-29 2:22 UTC (permalink / raw)
To: Jon Loeliger; +Cc: linuxppc-dev
Currently, fdt_path_offset() returns FDL_ERR_BADOFFSET if given a path
with a trailing '/'. In particular this means that
fdt_path_offset("/") returns FDT_ERR_BADOFFSET rather than 0 as one
would expect.
This patch fixes the function to accept and ignore trailing '/'
characters. As well as allowing fdt_path_offset("/") this means that
fdt_path_offset("/foo/") will return the same as
fdt_path_offset("/foo") which seems in keeping with the principle of
least surprise.
This also adds a testcase to ensure that fdt_path_offset("/") returns
0 as it should.

* dtc: Fix summary calculation in testsuite

To: Jon Loeliger; +Cc: linuxppc-dev
The bookkeeping for producing the testsuite summary (total number of
tests passed, failed and so forth) is broken. It uses $? across
several tests, but for checks after the first, the value of $? will no
longer contain the original return code, but just that from the
previous test. This patch fixes the problem.

This is why I think mmiowb() is not like a Linux memory barrier.
And I presume that the device would see IOs and regular stores from
a CPU in program order, given the correct wmb()s? (but maybe I'm
wrong... more below).

Hmm. So what if you had the following code executed by a single CPU:
writel(data, ioaddr);
wmb();
*mem = 10;
Will the device see the io write before the store to mem?

mmiowb needs to have the disclaimer that it's probably wrong if called
outside a lock, and it's probably wrong if called between two io writes
(need a regular wmb() in that case). I think some drivers are getting
this wrong.

Not at present, because the platforms *I'm* mostly targetting at the

use it for linkstation standby. This is version 2, taking into account
comments to the previous version and re-implementing MPC10x suspend in a

Fixed. The rest your comments are no longer relevant for this version,
since mpc10x_{suspend,resume} functions are not called directly from
linkstation.c, rather using late_suspend / early_resume (pci) hooks.

Well, I wasn't sure when PM can be used not meaning PM_SLEEP, so, I left
PM for now. Can certainly change, if it really matters.
A couple more thing:
1. the driver is called mpc10x.c, but the comment says it is for MPC8241.
I don't know what PCI IDs other fsl chips have and which of them are
compatible with 824[15].
2. the probe function, that just returns 0 seems to be redundant, but
without it device-driver linking is incomplete and suspend/resume are not
called.
3. the patch(es) from Scott Wood that are required for this one are still
not merged, and I cannot remember having seen any comments / objections...
Thanks

Yes there is, git commit e08e6c521355cd33e647b2f739885bc3050eead6.
On SN2 any user process performing memory-mapped IO directly to a
device needs something like mmiowb() to be performed at the node of
the CPU it last ran on when the task context switches onto a new CPU.
The current code performs this action for all inter-CPU context
switches, but we had discussed the possibility of targetting the
action only when the user process has actually mapped a device for
IO. I believe it was decided that this level of complexity wasn't
warranted unless this simple solution was found to cause a problem.
That reminds me. Are the people who are working on the user-level
driver effort including a capability similar to mmiowb()? If we
had that capability we could eventually do away with the change
mentioned above. But that would come after all user-level drivers
were coded to include the mmiowb()-like calls, and existing drivers
which provide mmap() capability directly to hardware go away.

I'm sure all of the following is already known to most readers, but
I thought the paragraph above might potentially cause confusion as
to the nature of the problem mmiowb() is solving on SN2. So for
the record...
SN2 does not reorder IOs issued from a single CPU (that would be
insane). Neither does it reorder IOs once they've reached the IO
fabric (equally insane). From an individual CPU's perspective, all
IOs that it issues to a device will arrive at that device in program
order.
(In this entire message, all IOs are assumed to be memory-mapped.)
The problem mmiowb() helps solve on SN2 is the ordering of IOs issued
from multiple CPUs to a single device. That ordering is undefined, as
IO transactions are not ordered across CPUs. That is, if CPU A issues
an IO at time T, and CPU B at time T+1, CPU B's IO may arrive at the
IO fabric before CPU A's IO, particularly if CPU B happens to be closer
than CPU B to the target IO bridge on the NUMA network.
The simplistic method to solve this is a lock around the section
issuing IOs, thereby ensuring serialization of access to the IO
device. However, as SN2 does not enforce an ordering between normal
memory transactions and memory-mapped IO transactions, you cannot
be sure that an IO transaction will arrive at the IO fabric "on the
correct side" of the unlock memory transaction using this scheme.
Enter mmiowb().
mmiowb() causes SN2 to drain the pending IOs from the current CPU's
node. Once the IOs are drained the CPU can safely unlock a normal
memory based lock without fear of the unlock's memory write passing
any outstanding IOs from that CPU.

No, the solution is to lock the interrupts onto one specific
processor and don't move it around. That's what's causing
all of the problems.
And you can enforce this policy now in the driver even if just
for testing by calling the set_affinity() interfaces on the
interrupts your driver has.
You can even walk over the cpu_online_map and choose a load
distribution of your liking.

* [PATCH 8/9] mpc82xx: Update mpc8272ads, and factor out PCI and reset.
From: Scott Wood @ 2007-08-28 20:19 UTC (permalink / raw)
To: galak; +Cc: linuxppc-dev
In-Reply-To: <20070828201127.GA24068@ld0162-tx32.am.freescale.net>
1. PCI and reset are factored out into pq2.c. I renamed them from m82xx
to pq2 because they won't work on the Integrated Host Processor line of
82xx chips (i.e. 8240, 8245, and such).
2. The PCI PIC, which is nominally board-specific, is used on multiple
boards, and thus is used into pq2ads-pci-pic.c.
3. The new CPM binding is used.
4. General cleanup.

* [PATCH 4/9] cpm2: Add cpm2_set_pin().
From: Scott Wood @ 2007-08-28 20:19 UTC (permalink / raw)
To: galak; +Cc: linuxppc-dev
In-Reply-To: <20070828201127.GA24068@ld0162-tx32.am.freescale.net>
This provides a generic way for board code to set up CPM pins, rather
than directly poking magic values into registers.

The hardware adds one to the BRG value to get the divider, so it must
be subtracted by software.

Mostly sparse fixes (__iomem annotations, etc); also, cpm2_immr
is used rather than creating many temporary mappings.

* [PATCH 7/9] 8xx: mpc885ads cleanup
From: Scott Wood @ 2007-08-28 20:19 UTC (permalink / raw)
To: galak; +Cc: linuxppc-dev
In-Reply-To: <20070828201127.GA24068@ld0162-tx32.am.freescale.net>
It now uses the new CPM binding and the generic pin/clock functions, and
has assorted fixes and cleanup.

* [PATCH 6/9] 8xx: Set initial memory limit.

The 8xx can only support a max of 8M during early boot (it seems a lot of
8xx boards only have 8M so the bug was never triggered), but the early
allocator isn't aware of this. The following change makes it able to run
with larger memory.

Why would RQ2's IRQ move over to CPU_1? That's stupid.
If you lock the IRQs to specific cpus, the load adjusts automatically.
Because packet work, in high load situations, will be processed via
ksoftirqd daemons even if the packet is not for a user application's
socket.
In such a case the scheduler will move the user applications that are
now not able to get their timeslices over to a less busy cpu.
If you keep moving the interrupts around, the scheduler cannot react
properly and it makes the situation worse.

* [PATCH 5/9] 8xx: Don't call non-existent Soft_emulate_8xx from SoftwareEmulation.
From: Scott Wood @ 2007-08-28 20:17 UTC (permalink / raw)
To: galak; +Cc: linuxppc-dev
In-Reply-To: <20070828201127.GA24068@ld0162-tx32.am.freescale.net>
On arch/ppc, Soft_emulate_8xx was used when full math emulation was
turned off to emulate a minimal subset of floating point load/store
instructions, to avoid needing a soft-float toolchain. This function
is called, but not present, on arch/powerpc, causing a build error
if floating point emulation is turned off.
As:
1. soft-float toolchains are now common,
2. partial emulation could mislead someone into thinking they have
a soft-float userspace because things usually work, only to have it
fail when actual FP gets executed under unusual circumstances, and
3. full emulation is still available for those who need to run
non-soft-float userspace,
I'm deleting the call rather than moving Soft_emulate_8xx over to
arch/powerpc.

* [PATCH 4/9] 8xx: Work around CPU15 erratum.
From: Scott Wood @ 2007-08-28 20:17 UTC (permalink / raw)
To: galak; +Cc: linuxppc-dev
In-Reply-To: <20070828201127.GA24068@ld0162-tx32.am.freescale.net>
The CPU15 erratum on MPC8xx chips can cause incorrect code execution
under certain circumstances, where there is a conditional or indirect
branch in the last word of a page, with a target in the last cache line
of the next page. This patch implements one of the suggested
workarounds, by forcing a TLB miss whenever execution crosses a page
boundary. This is done by invalidating the pages before and after the
one being loaded into the TLB in the ITLB miss handler.

+ This enables a workaround for erratum CPU15 on MPC8xx chips.
+ This bug can cause incorrect code execution under certain
+ circumstances. This workaround adds some overhead (a TLB miss
+ every time execution crosses a page boundary), and you may wish
+ to disable it if you have worked around the bug in the compiler
+ (by not placing conditional branches or branches to LR or CTR
+ in the last word of a page, with a target of the last cache
+ line in the next page), or if you have used some other
+ workaround.
