* [PATCH 2/2] mtd/nand : workaround for Freescale FCM to support large-page Nand chip
From: b35362 @ 2011-06-28 1:50 UTC (permalink / raw)
To: dwmw2; +Cc: Liu Shuo, linuxppc-dev, linux-mtd
In-Reply-To: <1309225852-1664-1-git-send-email-b35362@freescale.com>
From: Liu Shuo <b35362@freescale.com>
Freescale FCM controller has a 2K size limitation of buffer RAM. In order
to support the Nand flash chip whose page size is larger than 2K bytes,
we divide a page into multi-2K pages for MTD layer driver. In that case,
we force to set the page size to 2K bytes. We convert the page address of
MTD layer driver to a real page address in flash chips and a column index
in fsl_elbc driver. We can issue any column address by UA instruction of
elbc controller.

* [PATCH 1/2] mtd/nand : don't free the global data fsl_lbc_ctrl_dev->nand in fsl_elbc_chip_remove()

From: Liu Shuo <b35362@freescale.com>
The global data fsl_lbc_ctrl_dev->nand don't have to be freed in
fsl_elbc_chip_remove(). The right place to do that is in fsl_elbc_nand_remove()
if elbc_fcm_ctrl->counter is zero.

You are applying a bandage on a wooden leg here .... userspace (vDSO)
will see the time going backward if you aren't well synchronized as
well, so you're stuffed anyways.

To: benh; +Cc: linuxppc-dev
As is done in read_tsc() on x86, make sure that we don't return a timebase
value smaller than cycle_last, which can happen on SMP if the timebases are
not perfectly synchronized. It is less expensive than total enforcement of
monotonicity, since we don't need to add another variable and update it on
each read, but it will prevent core timekeeping functions from translating
a small timebase regression into a large jump forward.

* [PATCH 1/2] powerpc/85xx: Add P3041 SoC device tree include stub
From: Kumar Gala @ 2011-06-27 13:44 UTC (permalink / raw)
To: linuxppc-dev
Split out common (non-board specific) parts of the SoC related device
tree into a stub so multiple board dts files can include it and we can
reduce duplication and maintenance effort.

Yes, here is the output from a canyonlands (460ex) that exhibits
the same problem and in the same place. Of the two devices
I have that fail (sil24 and one other), both fail in exactly
the same place in lib/devres.c within the function
pcim_iomap_regions. In that function, there is the
following call -- it fails b/c len returns 0 and tha failure
bubbles up to "error -22".
len = pci_resource_len(pdev, i);

That was my initial thought as well, but I wasn't versed
enough in the pci magic in order to completely figure it
out.
Here is the output, it is dmesg, iomem, then ioports for the
passing and then the failing cases.
thanks

Can you send a dmesg & output of /proc/iomem & ioport with and without
the patch (same kernel otherwise) ?
Also can you try to figure out (printk's) where in the driver does it
fail ? (Which function fails)
It's possible that this changes something in the core resource
assignment code causing something else to fail elsewhere or exposing
another bug elsewhere with the consequence of leaving the SiL with badly
assigned resources.
Cheers,
Ben.

Catch up with Tony (CC), he's working on something similar for a new
variant of that PCIe controller used internally by some IBM stuff.

Well, briefly we build a custom processor board that has
a couple powerpcs on it and some pcie switches. We end up
plugging our devices into the switches which is unlike what
most people try. In any case, we use several different
drive controllers for SAS, SCSI, and SSDs. For testing
purposes (i.e. when things don't go the way they should) we
have an adapter to make "regular" pcie slots that we plug in
whatever. But our switches are on the board with the CPUs
so as far as the CPU goes, it will always see a gen-2 link
8 lane link, irrespective of what the endpoint actually is.
We let the switches handle the speed changes and the port
bifurcation.

Ok, so I am back from doing whatever it is that I do. Shall
I go ahead and take a stab at making a new functor to handle
the "link check"? -- which IIRC was the thought from last
month about how best to handle the 460SX and whatever some
people were using internally.

On powerpc, we emulate sstep whenever possible. Only recently support to
emulate loads and stores got added. I don't have access to a powerpc box
today... but will try to recreate the problem ASAP and see what could be
happening in the presence of mcount.

Gabriel, Michael, do you recognise this bug? Are there any fixes for
Pegasos that are missing from 3.0-rc3?
