Fair point. Perhaps this should be documented in the Documentation, if

I am ok with that. We can revisit the problem if IPI noise becomes
noticable. However, if Nathan or Michael feel that this problem is
better solved now, than leaving it for the future, we will have to
take a call on what the interface is going to be.

Crash paths should not take that RTAS lock, it's a massive pain. I'm
fixing it for machine check, for other crashes I think it can be removed
too, it just needs to be unpicked. The good thing with crashing is that
you can reasonably *know* that you're single threaded, so you can
usually reason through situations like above.

Yes. It's been a bit painful, but in the long term it means that a CPU
which hangs with interrupts off can be debugged, and it means we can
take it offline to crash without risking that it will be clobbering what
we're doing.
Arguably what I should have done is try a regular IPI first, wait a few
seconds, then NMI IPI.
A couple of problems with that. Firstly it probably avoids this issue
you hit almost all the time, so it won't get fixed. So when we really
need the NMI IPI in the field, it'll still be riddled with deadlocks.
Secondly, sending the IPI first in theory can be more intrusive to the
state that we want to debug. It uses the currently running stack, paca
save areas, ec. NMI IPI uses its own stack and save regions so it's a
little more isolated. Maybe this is only a small advantage but I'd like
to have it if we can.
Thanks,
Nick

while PPC_PSERIES is not set, gcc build fails:
arch/powerpc/mm/ptdump/hashpagetable.c: In function ‘pseries_find’:
arch/powerpc/mm/ptdump/hashpagetable.c:262:18: error: ‘H_SUCCESS’ undeclared (first use in this function); did you mean ‘FL_ACCESS’?
if (lpar_rc != H_SUCCESS)
^~~~~~~~~
FL_ACCESS
If PPC_PSERIES is not set, <asm/plpar_wrappers.h> does not
include <asm/hvcall.h>, which leads to this failure.
Add missing include file <asm/hvcall.h> in hashpagetable.c to fix this.

I think we would like to replace CONFIG_NODES_SPAN_OTHER_NODES with
CONFIG_NUMA, and just let UMA return 0 as node id, as Michal replied in
another mail. Anyway, your patch 2~5 are still needed to sit on top of
the change of this new plan.

Sorry for the late reply, busy trying to fix bugs in the C rewrite
series. I don't think it is the right place, it should be in the
ppc32 implementation detail. ppc64 has an equivalent comment at the
top of its read_user_stack functions.

It's fine in this case, that warning is about not introducing
runtime bugs, but this wouldn't be.
But... I actually don't like adding read_user_stack_slow on 32-bit
and especially not just to make IS_ENABLED work.
IMO this would be better if you really want to consolidate it

Agh, I'm hopeless.
I don't think it really resolves this issue. But probably don't have time
to look at generated asm, and might never because it won't really hit
LE unless we add a 32-bit ABI. It's pretty minor though either way.
Sorry for being difficult, I really do like your patches :)

* [PATCH v2 1/5] uaccess: Add user_read_access_begin/end and user_write_access_begin/end
From: Christophe Leroy @ 2020-04-03 7:20 UTC (permalink / raw)
To: Benjamin Herrenschmidt, Paul Mackerras, Michael Ellerman, airlied,
daniel, torvalds, viro, akpm, keescook, hpa
Cc: linux-arch, linux-mm, intel-gfx, linuxppc-dev, linux-kernel
Some architectures like powerpc64 have the capability to separate
read access and write access protection.
For get_user() and copy_from_user(), powerpc64 only open read access.
For put_user() and copy_to_user(), powerpc64 only open write access.
But when using unsafe_get_user() or unsafe_put_user(),
user_access_begin open both read and write.
Other architectures like powerpc book3s 32 bits only allow write
access protection. And on this architecture protection is an heavy
operation as it requires locking/unlocking per segment of 256Mbytes.
On those architecture it is therefore desirable to do the unlocking
only for write access. (Note that book3s/32 ranges from very old
powermac from the 90's with powerpc 601 processor, till modern
ADSL boxes with PowerQuicc II processors for instance so it
is still worth considering.)
In order to avoid any risk based of hacking some variable parameters
passed to user_access_begin/end that would allow hacking and
leaving user access open or opening too much, it is preferable to
use dedicated static functions that can't be overridden.
Add a user_read_access_begin and user_read_access_end to only open
read access.
Add a user_write_access_begin and user_write_access_end to only open
write access.
By default, when undefined, those new access helpers default on the
existing user_access_begin and user_access_end.

This series is based on the discussion we had in January, see
https://patchwork.ozlabs.org/patch/1227926/ . I tried to
take into account all remarks, especially @hpa 's remark to use
a fixed API on not base the relocking on a magic id returned at
unlocking.
This series is awaited for implementing selective lkdtm test to
test powerpc64 independant read and write protection, see

Now we have user_read_access_begin() and user_write_access_begin()
in addition to user_access_begin().
Make it explicit that user_access_begin() provides both read and
write by renaming it user_full_access_begin(). And the same for
user_access_end() which becomes user_full_access_end().
Done with following command, then hand splitted two too long lines.

These all look good to me. I had some minor comment about one patch but
not really a big deal and there were more cleanups on top of it, so I
don't mind if it's merged as is.
Actually I think we have a bit of stack reading fixes for 64s radix now
(not a bug fix as such, but we don't need the hash fault logic in radix),
so if I get around to that I can propose the changes in that series.
Thanks,
Nick

Oh great, nice work. We should be able to make some simple helpers or
move some things a bit to reduce the amount of ifdefs in the C code.
It doesn't look too bad though.

What's the performance difference between current asm code just with
always saving NVGPRS vs C?

OK I think I've fixed it, KPROBES_SANITY_TEST passes too. I'd

Hi Wen,
Can you please try this? It contains 3 patches from Christoph Hellwig
plus my patch on top, this should improve performance when DMA-ing not
to/from persistent memory:
https://github.com/aik/linux/commits/dma-bypass.3
I am looking for any benchmarks not related to persistent memory. Thanks,

How complex would it be to provide a QEMU PowerNV model for the NX and
VAS units ? We can stage the different level of support. First would be
a simple HW init. I am interested for the XIVE modeling of course.

I am trying now this approach on top of yours "dma-bypass.3" (it is
"wip", needs an upper boundary check):
https://github.com/aik/linux/commit/49d73c7771e3f6054804f6cfa80b4e320111662d
Do you see any serious problem with this approach? Thanks!
