I think that the idea here is that we only have possibly one master in
the system which offers indirectIO backend, so another one could not
possibly re-set this value.

The concern would be that some architecture which uses generic
higher-level ISA accessor ops, but have IO space, could be affected.

Right, given that it's never worked and the failure only seems to crop up
in synthetic testing, I think you can queue these for 4.10.

It's sad that we need to hardcode those indexes in the Device Tree
(which by no means are a description of the HW by the way), but that's
what the SPI framework expects I believe. Therefore:

Why is that assumption valid, and why does WRITE_ONCE help there? It's not
ONCE as in WARN_ONCE, more ONCE as in exactly-once-per-invocation.

You're already adding a Kconfig symbol for this stuff, so you can keep
that if you don't want it on other architectures. I'm just arguing that
plumbing drivers directly into arch code via arm64_set_extops is not
something I'm particularly fond of, especially when it looks like it

Right. Devices are enumerated by generic code beginning from '0' on
each bus (AP806, CP110-master, CP110-slave) independently and
I didn't see any nice solution for it either.

* [PATCH] arm: imx6qp: correct LDB clock inputs
From: Lucas Stach @ 2016-11-08 16:55 UTC (permalink / raw)
To: linux-arm-kernel
On i.MX6QP the LDB clock tree has changed to move the clk gate
before the divider, to prevent clock glitches propagating downstream.
A consequence of this change is that the clk divider is now the
parent of the LDB inputs. Reflect this change in the devicetree
to allow the LDB driver to properly configure the display clocks.

It's only valid based on the inherent assumption that all indirectIO is
redirected to one backend master, i.e. LPC driver.
Anyway, right, I don't think that WRITE_ONCE is correct. Zhichang was
looking for something which would only allow the pointer to be written
once ever.

Ok, so the use of those address spaces is an artifact of the ISA
controller being a device under the PCI host bridge.
Given we can have multiple domains, surely that implies we can have
multiple ISA controllers in general?

I'm worried that this might not be a safe assumption. Hardware these
days has a habit of pushing the boundaries of our expectations.
If we're going to assume that, I'd certainly want the kernel to verify
that it's true for all instanciated ISA/LPC devices. Otherwise, I can
imagine people relying on (or working around) that assumption in ACPI
tables and DTs, and that will be a nightmare (at best) to untangle in
future.
Thanks,
Mark.

I had a chance to discuss this patchset with SteveR and PeterZ at LPC
and both don't like the idea of introducing notifications on perf trace
event [un]registration.
Peter suggested using the PMU interface to expose this functionality. As
we want to monitor TLB instructions for for each VM, this will require
creating a PMU per-VM. The PMU events can be extended in the future if
monitoring of additional operations is supported and required.
I'll post the next version with the above changes - please chime-in if
you disagrees with this approach.

* [PATCH 0/10] ARM: sun5i: Convert sun5i SoCs to sunxi-ng
From: Maxime Ripard @ 2016-11-08 17:23 UTC (permalink / raw)

Hi,
This is yet another serie bringing more SoCs into the sunxi-ng world.
This is pretty common stuff. Dealing with more corner cases, and adding the
drivers for the SoCs. The A10 and A20 should be pretty close, and pretty
easy to support after that.
Let me know what you think,

* [PATCH 3/10] clk: sunxi-ng: Implement multiplier offsets
From: Maxime Ripard @ 2016-11-08 17:23 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <cover.326f50aecc25fbe292184527b52a1e3172aba9cf.1478625788.git-series.maxime.ripard@free-electrons.com>
The multipliers we've seen so far all had an offset of one. However, on the
earlier Allwinner SoCs, the multipliers could have no offset at all.
Implement an additional field for the multipliers to specify that offset.
Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com>

* [PATCH 4/10] clk: sunxi-ng: Add clocks and resets indices for sun5i
From: Maxime Ripard @ 2016-11-08 17:23 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <cover.326f50aecc25fbe292184527b52a1e3172aba9cf.1478625788.git-series.maxime.ripard@free-electrons.com>
The SoCs part of the sun5i family share the DTs, so we need consistant
indices in order to still share the DTs.

* [PATCH 9/10] ARM: sun5i: Convert to CCU
From: Maxime Ripard @ 2016-11-08 17:23 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <cover.326f50aecc25fbe292184527b52a1e3172aba9cf.1478625788.git-series.maxime.ripard@free-electrons.com>
Now that we have drivers for all of them, convert all the SoCs that share
the sun5i DTSI to the new CCU driver.
Signed-off-by: Maxime Ripard <maxime.ripard@free-electrons.com>

* [PATCH 10/10] ARM: gr8: Convert to CCU
From: Maxime Ripard @ 2016-11-08 17:23 UTC (permalink / raw)
To: linux-arm-kernel
In-Reply-To: <cover.326f50aecc25fbe292184527b52a1e3172aba9cf.1478625788.git-series.maxime.ripard@free-electrons.com>
Now that we have a driver for the GR8, we can convert our DT to it.

Shawn, is it okay if that patch goes through your ARM/iMX tree?

This again because of incompatibility of the configuration data saved in
NOR flash. The erase command I gave early is to erase that when you
switched between the UEFI binaries. It's really horrible mess UEFI
created in the initial days of Juno, and hopefully they have moved to
some standard format these days.

I completely agree. I had real bad times in past dealing with such
things in UEFI.

I think startup.nsh needs some edits. Just replace it with something like:
"norkern dtb=board.dtb console=ttyAMA0,115200n8 root=/dev/nfs rw
rootwait ip=dhcp systemd.log_target=null nfsroot=..." or something
alike. Currently it just echos and stops.
Regarding the new firmware stopping abruptly, I have no clue, except
asking you to erase the flash completely when switching between the
firmware versions. That has worked for me for all UEFI related issues in
the past. It's really annoying I understand.
