[v2] ARM: remove name from machine_desc for DT platforms

Commit Message

From: Rob Herring <[e-mail]>

As part of the effort to ultimately remove struct machine_desc, the
machine name is not really needed. It is only used for /proc/cpuinfo
"Hardware" field. Get this information from the DT instead and remove
the name string in the machine descriptor for DT machine descriptors. The
model or machine compatible property from the DT is used instead.

This likely changes the name reported by /proc/cpuinfo. There could be
some userspace dependencies on the old name. Debian libdebian-installer
used to use this to determine kernel flavour, but now uses the DT
directly. It is not really a good idea for userspace to depend on this
anyway.

Kevin, Olof,

Here is updated patch based on arm-soc for-next and my DT for-next 
branches. I plan to get the DT changes in early in the merge window.

The patch is also available here:

I've obviously missed some discussions because I wasn't aware of the
plan to remove machine_desc. That's neither here not there, but for as
long as the structure still exists it is really useful to discover
which machine_desc the kernel chooses at boot time. If you're going to
remove this, then at the very least I would embed the filename or
something similar into the machine desc so it is available for
debugging. It can go away when the structure is removed.

It's a very long term goal to remove it completely, but it is now
optional for "simple" platforms with the default machine_desc and
default init ptrs. You might want to look at the patches and the WIP
branch I posted[1] which removes the machine_desc for highbank.
There's some core boilerplate I'd like your opinion on. Also, I'm sure
you are aware of the resistance to add a machine_desc to arm64, so I'm
looking at this from that perspective as well. I'm sure there will be
platforms which look very similar across arm and arm64.

On boot, the model or compatible string from the DTB is printed out
(that change is actually in my DT arch clean-up series, not this
patch). This has made what is printed out on boot consistent across
arches using DT. There is no good reason for this to be arch specific.
Presumably the compatible string is unique and just as easily grepped
for in the kernel source as the machine_desc name is. Adding a
filename string here seems like useless bloat to me.

So in the case of a DTS for a generic, get-started-here board with no
"external" features, you might see "fsl,imx53" as your board name?

Not necessarily. Most compatible strings in the root node have more
than one string (fsl,imx51-babbage, fsl,imx51) - which do you print?
First? Both/All? Without the model property it's not completely
deterministic (since it's externally provided data, no matter what)
and I don't see code that brings out more than one.

Essentially meaning for anything that never had or never will have a
true model property, something a little more relevant (and entirely
deterministic per-SoC) ends up in the device property.

I really like the idea of ditching machine_desc, but this is one place
where probably init code for the board is the place to parse (and
stuff in) the board name to some global structure.

BTW with the of matching patch, what REALLY guarantees ordering of
these calls, for instance how does it replace map_io, init_irq, etc.?
Highbank seems a special case where it basically didn't need or do any
of this so it's not affected by it going away. What I'm trying to
understand is what replaces those hooks, because I'd like to throw
this into i.MX and see what happens, but I'm not sure what the
eventual goal is. Nonetheless I like the theme;

I think I agree a bit with Grant's concern here.

The compatible string is unique, but the machine descriptors might not
be -- a given device tree might match two of them (one more generic,
one more specific) -- it would be useful to know which one was used. Or,
if you missed to enable the platform support for your board so it booted
with the generic descriptor, but you still needed your own.

Matching it back to which devicetree the kernel was booted with shouldn't be
hard, I agree -- but knowing which machine entry was picked at boot time
is still useful information.

Snip.. I actually reviewed what you're doing since I was
understandably curious as to what the "plan" is for removing
machine_desc and how you'd potentially avoid end up stashing global
variables all over the place for early init code..

This machine doesn't have a .dt_compat so...

In your case here, isn't this going to print "calxeda,highbank" for
you right now, with a broken tree, since it's the first in your
dt_compat list?

In the generic case, as noted above, the compatibility list usually comes out as

                         ID (hex)       NAME
                         :
                         0xffffffff        Highbank
                         0xffffffff        Generic DT based system

But you've made it say:

                         ID (hex)        NAME
                         :
                         0xffffffff         calxeda,highbank
                         0xffffffff

You didn't fix your customer issue there, at least, if they're messing
with their DT and break it ;)

Also you missed around line 242 of kernel/devtree.c which prints
mdesc_best->name;

        model = of_get_flat_dt_prop(dt_root, "model", NULL);
        if (!model)
                model = of_get_flat_dt_prop(dt_root, "compatible", NULL);
        if (!model)
                model = "<unknown>";
        pr_info("Machine: %s, model: %s\n", mdesc_best->name, model);

Which is now going to say "Machine: , model: Calxeda Foo Board", isn't it?

Should just use machine_name, if mdesc_best->name isn't set, shouldn't it?

I think there's a bunch of weirdness here.. I just checked the PAPR
and ePAPR specs, and the original IEEE1275 and ARM bindings and
finding board information like you want from the DT is an unholy
crapshoot.

In this case I think we need more information, and to only print it
once per boot if that's the goal here. Why not make machine_name an
argument to setup_machine_fdt (or just don't have it be static in
setup.c) and have that function fill in the right thing rather than
having a DT parsing function in setup_arch where before it was totally
boot-method agnostic?

This is not the issue I'm trying to fix as this is a debug early print.
It is what /proc/cpuinfo displays.

I don't think your example is even possible. If we have the default
descriptor enabled (i.e. all multi-platform builds), then we will always
match a machine descriptor and try to continue to boot never reaching
this code path.

You are looking at the wrong version. See the DT clean-up that I did
which is in mainline now. This patch is dependent on that.

Maybe in the past, but we require a root compatible string. If there is
no model property, then the compatible string is the machine name.

Well, that's an implementation detail. First we have to agree on which
string gets used and where.
