Subject: [PATCH 00/16] remove eight obsolete architectures

Here is the collection of patches I have applied to my 'asm-generic' tree
on top of the 'metag' removal. This does not include any of the device
drivers, I'll send those separately to a someone different list of people.

The removal came out of a discussion that is now documented at
https://lwn.net/Articles/748074/

Following up from the state described there, I ended up removing the
mn10300, tile, blackfin and cris architectures directly, rather than
waiting, after consulting with the respective maintainers.

However, the unicore32 architecture is no longer part of the removal,
after its maintainer Xuetao Guan said that the port is still actively
being used and that he intends to keep working on it, and that he will
try to provide updated toolchain sources.

In the end, it seems that while the eight architectures are extremely
different, they all suffered the same fate: There was one company in
charge of an SoC line, a CPU microarchitecture and a software ecosystem,
which was more costly than licensing newer off-the-shelf CPU cores from
a third party (typically ARM, MIPS, or RISC-V). It seems that all the
SoC product lines are still around, but have not used the custom CPU
architectures for several years at this point.

Subject: [PATCH 03/16] arch: remove m32r port

The Mitsubishi/Renesas m32r architecture has been around for many years,
but the Linux port has been obsolete for a very long time as well, with
the last significant updates done for linux-2.6.14.

While some m32r microcontrollers are still being marketed by Renesas,
those are apparently no longer possible to support, mainly due to the
lack of an external memory interface.

Hirokazu Takata was the maintainer until the architecture got marked
Orphaned in 2014.

Subject: [PATCH 04/16] arch: remove score port

The Sunplus S+core architecture was added in 2009 by Chen Liqin,
who has been co-maintaining it with Lennox Wu <[email protected]>
since then, but after they both left the company, nobody else has shown
any interest in the port and it has seen almost no activity other than
tree-wide changes.

The gcc port was removed a few years ago due to the inactivity.

While the sunplus website still advertises products with unspecified
RISC cores that might be S+core based, it's very clear that the Linux
port is completely abandoned at this point.

This removes all files related to the architecture.

Subject: [PATCH 02/16] arch: remove frv port

The Fujitsu FRV kernel port has been around for a long time, but has not
seen regular updates in several years and instead was marked 'Orphaned'
in 2016 by long-time maintainer David Howells.

The SoC product line apparently is apparently still around in the form
of the Socionext Milbeaut image processor, but this one no longer uses
the FRV CPU cores.

This removes all FRV specific files from the kernel.

Subject: [PATCH 05/16] arch: remove blackfin port

The Analog Devices Blackfin port was added in 2007 and was rather
active for a while, but all work on it has come to a standstill
over time, as Analog have changed their product line-up.

Aaron Wu confirmed that the architecture port is no longer relevant,
and multiple people suggested removing blackfin independently because
of some of its oddities like a non-working SMP port, and the amount of
duplication between the chip variants, which cause extra work when
doing cross-architecture changes.

Subject: [PATCH 06/16] arch: remove tile port

The Tile architecture port was added by Chris Metcalf in 2010, and
maintained until early 2018 when he orphaned it due to his departure
from Mellanox, and nobody else stepped up to maintain it. The product
line is still around in the form of the BlueField SoC, but no longer
uses the Tile architecture.

There are also still products for sale with Tile-GX SoCs, notably the
Mikrotik CCR router family. The products all use old (linux-3.3) kernels
with lots of patches and won't be upgraded by their manufacturers. There
have been efforts to port both OpenWRT and Debian to these, but both
projects have stalled and are very unlikely to be continued in the future.

Given that we are reasonably sure that nobody is still using the port
with an upstream kernel any more, it seems better to remove it now while
the port is in a good shape than to let it bitrot for a few years first.

Subject: [PATCH 07/16] CRIS: Drop support for the CRIS port

From: Jesper Nilsson <[email protected]>

The port was added back in 2000 so it's no longer even a good source
of inspiration for newer ports (if it ever was)

The last SoC (ARTPEC-3) with a CRIS main CPU was launched in 2008.

Coupled with time and working developer board hardware being
in low supply, it's time to drop the port from Linux.

So long and thanks for all the fish!

Subject: [PATCH 10/16] mm: remove obsolete alloc_remap()

Tile was the only remaining architecture to implement alloc_remap(),
and since that is being removed, there is no point in keeping this
function.

Removing all callers simplifies the mem_map handling.

Subject: [PATCH 11/16] treewide: simplify Kconfig dependencies for removed archs

A lot of Kconfig symbols have architecture specific dependencies.
In those cases that depend on architectures we have already removed,
they can be omitted.

Subject: Re: [PATCH 10/16] mm: remove obsolete alloc_remap()

Hi Arnd,

I like this cleanup, but arch/tile (which is afaik Orphaned but still in the gate) has:

HAVE_ARCH_ALLOC_REMAP set to yes:

arch/tile/Kconfig
config HAVE_ARCH_ALLOC_REMAP
def_bool y

Define in arch/tile/kernel/setup.c:
void *__init alloc_remap(int nid, unsigned long size)
{
int pages = node_end_pfn[nid] - node_start_pfn[nid];
void *map = pfn_to_kaddr(node_memmap_pfn[nid]);
BUG_ON(size != pages * sizeof(struct page));
memset(map, 0, size);
return map;
}

Thank you,
Pavel

Subject: [PATCH 13/16] Documentation: arch-support: remove obsolete architectures

A number of architecture ports are obsolete and getting dropped,
so we no longer want to track the respective features.

We already removed the lines for metag and mn10300, this does
the same edits for all the others.

For the remaining 21 architectures, this shows how many are known
to implement each given feature:

need to be added.

It was a bit tricky to juggle the Cc lists here, but tile is removed
in patch 06/10
now. As I explained in the cover letter, it was originally planned to be marked
deprecated for a while first, but after some more discussion, nobody could come
up with a reason to keep it any longer. Same thing for mn10300,
blackfin and cris.

AFAICS, score is the only architecture which still defines

__ARCH_WANT_SYSCALL_NO_FLAGS

Subject: [PATCH 14/16] asm-generic: clean up asm/unistd.h

The score architecture used a number of old system calls for compatibility
with a traditional libc port, all architectures that got added later
skip these. With score out of the way, we can finally clean up the
syscall list to no longer provide these.

Definitely. In fact, this was patch 14/16, but for some reason the mail never
made it out. I tried again and it should be there now.

Yes, plenty. I was wondering the same thing, but it seems that the architectures
we remove are almost completely representative of what we support overall,
except that they are all not licensed to 3rd parties, unlike many of the ones we
keep.

I've made an overview of the remaining architectures for my own reference[1].
The remaining NOMMU architectures are:

- arch/arm has ARMv7-M (Cortex-M microcontroller), which is actually
gaining traction
- arch/sh has an open-source J2 core that was added not that long ago,
it seems to
be the only SH compatible core that anyone is working on.
- arch/microblaze supports both MMU/NOMMU modes (most use an MMU)
- arch/m68k supports several NOMMU targets, both the coldfire SoCs and the
classic processors
- c6x has no MMU

If I am reading siginfo.h correctly after this cleanup patch
we can perform another cleanup and unconditionally define
all of the ia64 si_codes except for __SEGV_PSTKOVF which
aliases SEGV_PKUERR.

Which has the advantage that no one is tempted to define any further
aliased si_codes.

Is anyone producing a chip that includes enough of the Privileged ISA spec
to have things like system calls, but not the MMU parts?

I thought at least initially the kernel only supports hardware that has a rather
complete feature set.

Yes.

I just realized you can also remove the #ifdefs for BUS_MCEERR_AR,
BUS_MCEERR_AO, and SEGV_BNDERR. As those si_codes are now always
defined. That description I expect you can handle.

For a description of the above change how does this sound?

Unlike system call numbers the assignment of si_codes has never had a
reason to be made per architecture. Some architectures have had unique
conditions to report and reporting those conditions needed new si_codes.
Nothing has ever needed si_codes to have different values on different
architectures. The si_code space is vast so even with defining all
si_codes on all architectures there is no danger in running out of
si_code values.

The history of the si_codes BUS_MCEERR_AR, BUS_MCEER_AO, SEGV_BNDERR,
and SEGV_PKUERR show that a need of one architecture frequently becomes
a need of another architecture which makes sharing si_codes between
architectures a positive benefit and something to be encouraged.

Where there are no conflicts with the historical ia64 arch specific
si_codes and any other si_codes make them generic si_codes. We might
need them on another architecture someday.

This leaves only the good example of arch generic si_codes in the kernel
for future architectures and architecture enhancments to follow.
Without bad examples to follow it should be easy to avoid the mistakes
of the past.

My existing patch already does this, and I've added a note to the changelog
as well now.

Ok, done. I've listed you as 'Suggested-by' for that patch. Since the
changelog is way more work than the actual change, I would have
made you the author of that patch, but I don't have a Signed-off-by
from you for it.

Various SiFive SOCs seem to support M and U mode, but no S mode or
iommu. That should be enough for nommu Linux running in M mode if
someone cares enough to actually port it.

I have a patchset that creates a vsprintf extension for
print_vma_addr and removes all the uses similar to the
print_symbol() removal.

This now avoids any possible printk interleaving.

Unfortunately, without some #ifdef in vsprintf, which
I would like to avoid, it increases the nommu kernel
size by ~500 bytes.

Anyone think this is acceptable?

Here's the overall patch, but I have it as a series

This doesn't feel like a huge win since it's only called ~once per
architecture. I'd be more excited if it made the printing of the whole
thing standardised; eg we have a print_fault() function in mm/memory.c
which takes a suitable set of arguments.

Sure but perhaps that's not feasible as the surrounding output
is per-arch specific.

What could be a standardized fault message here?

I did not see the changes to kernel/signal.c and fs/signalfd.c that
remove the #ifdef BUS_MCERR_AR etc. Did I miss that patch.

For however much it helps.

Arnd, thanks for dealing with this.

There are a number of tile-specific driver files that are mostly called out
in the MAINTAINERS file. I would expect you should also delete those.

-F:    drivers/char/tile-srom.c
-F:    drivers/edac/tile_edac.c
-F:    drivers/net/ethernet/tile/
-F:    drivers/rtc/rtc-tile.c
-F:    drivers/tty/hvc/hvc_tile.c
-F:    drivers/tty/serial/tilegx.c
-F:    drivers/usb/host/*-tilegx.c

ARMv7-R as well, also seems ARM is coming up with more !MMU's - v8-M,
v8-R. In addition, though only of academic interest, ARM MMU capable
platform's can run !MMU Linux.

Right. I covered all of those in my follow-up driver series, see
https://lkml.org/lkml/2018/3/14/579

It's all in linux-next as of yesterday, but thanks for paying attention here.

We currently do not have a NOMMU port. As far as I know, everyone who's
currently producing RISC-V hardware with enough memory to run Linux has S mode
with paging support. The ISA allows for S mode without paging but there's no
hardware for that -- if you're going to put a DRAM controller on there then
paging seems pretty cheap. You could run a NOMMU port on a system with S-mode
and paging, but With all the superpage stuff I don't think you'll get an
appreciable performance win for any workload running without an MMU so there's
nothing to justify the work (and incompatibility) of a NOMMU port there.

While I think you could implement a NOMMU port on a machine with only M and U
modes (and therefor no address translation at all), I don't know of any MU-only
machines that have enough memory to run Linux (ours have less than 32KiB). A
SBI-free Linux would be a prerequisite for this, but there's some interest in
that outside of a NOMMU port so it might materialize anyway.

Of course, QEMU could probably be tricked into emulating one of these machines
with little to no effort :)... That said, I doubt we'll see a NOMMU port
materialize without some real hardware as it's a lot of work for a QEMU-only
target.
