This is not the correct config file. Can you send the .config ?

This fixes it for me. But we may have to look at the other arch details

Otherwise, we can call boot_init_stack_canary() from start_secondary()
before calling cpu_startup_entry() can't we ?

Thanks, Michael.
Kees, can you take the patches?
Apparently, neither signal.h nor compat.h have a dedicated maintainer:
$ scripts/get_maintainer.pl --nokeywords --nogit --nogit-fallback include/linux/signal.h
linux-kernel@vger.kernel.org (open list)
$ scripts/get_maintainer.pl --nokeywords --nogit --nogit-fallback include/linux/compat.h
linux-kernel@vger.kernel.org (open list)
Thanks

* [PATCH v5] powerpc/64s: reimplement book3s idle code in C
From: Nicholas Piggin @ 2018-10-12 11:22 UTC (permalink / raw)
To: linuxppc-dev
Cc: Gautham R . Shenoy, Mahesh Jagannath Salgaonkar, Nicholas Piggin,
kvm-ppc, Aneesh Kumar K.V, Akshay Adiga
Reimplement Book3S idle code in C, moving POWER7/8/9 implementation
speific HV idle code to the powernv platform code.
Book3S assembly stubs are kept in common code and used only to save
the stack frame and non-volatile GPRs before executing architected
idle instructions, and restoring the stack and reloading GPRs then
returning to C after waking from idle.
The complex logic dealing with threads and subcores, locking, SPRs,
HMIs, timebase resync, etc., is all done in C which makes it more
maintainable.
This is not a strict translation to C code, there are some
significant differences:
- Idle wakeup no longer uses the ->cpu_restore call to reinit SPRs,
but saves and restores them itself.
- The optimisation where EC=ESL=0 idle modes did not have to save GPRs
or change MSR is restored, because it's now simple to do. ESL=1
sleeps that do not lose GPRs can use this optimization too.
- KVM secondary entry and cede is now more of a call/return style
rather than branchy. nap_state_lost is not required because KVM
always returns via NVGPR restoring path.

Notes:
- P9 restores some of the PMU SPRs, but not others, and P8 only zeroes
them. There are improvmets to be made to SPR save restore policies and
documentation, but this first pass tries to keep things as they were.
Left to do:
- Test actual POWER7 hardware.
- KVM could use more review, it's pretty tricky. Not sure if what
I'm doing with the emergency stack is kosher. But it runs pretty fine
here with a POWER8 SMP+SMT guest. Possible to streamline
KVM cede code now that idle function saves nv gprs for us?
Since RFC v1:
- Now tested and working with POWER9 hash and radix.
- KVM support added. This took a bit of work to untangle and might
still have some issues, but POWER9 seems to work including hash on
radix with dependent threads mode.
- This snowballed a bit because of KVM and other details making it
not feasible to leave POWER7/8 code alone. That's only half done
at the moment.
- So far this trades about 800 lines of asm for 500 of C. With POWER7/8
support done it might be another hundred or so lines of C.
Since RFC v2:
- Fixed deep state SLB reloading
- Now tested and working with POWER8.
- Accounted for most feedback.
Since RFC v3:
- Rebased to powerpc merge + idle state bugfix
- Split SLB flush/restore code out and shared with MCE code (pseries
MCE patches can also use).
- More testing on POWER8 including KVM with secondaries.
- Performance testing looks good. EC=ESL=0 is about 5% faster, other
stop states look a little faster too.
- Adjusted SPR saving to handler POWER7, haven't tested it.
Since submission v1:
- More review comments from Gautham.
- Rename isa3_ to isa300_ prefix.
- Tinkered with some comments, copyright notice, changelog.
- Cede and regular idle do not go via KVM secondary wakeup code path,
so hwthread_state stores and barriers can be simplified, and some
KVM code paths simplified a little.
Since v2:
- Rebase, SLB reload patch has been merged.
- More testing. Tested machine check idle wakeup path with mambo stepping
through instructions.
Since v3:
- Build fixes caught by CI
Since v4:
- PSSCR test PLS rather than RL (Akshay)

That's no reason to make changes or drop the original author. You should
also indicate this is v9 and provide revision history.

I looked into the code more and noticed move_pte() helper called from
move_ptes(). It changes PTE entry to suite new address.
It is only defined in non-trivial way on Sparc. I don't know much about
Sparc and it's hard for me to say if the optimization will break anything
there.
I think it worth to disable the optimization if __HAVE_ARCH_MOVE_PTE is
defined. Or make architectures state explicitely that the optimization is
safe.

Hm. What guarantees that new_addr is PMD_SIZE-aligned?
It's not obvious to me.

I think calling again boot_init_stack_canary() will be an issue for all
arches using global canary.
As far as I can see, PPC and X86 are the only arches using non global.

What sparc is doing in move_pte() is flushing the data-cache
(synchronously) if the virtual address color of the mapping changes.
Hope this helps.

This is because all huge pages are larger than SHMLBA. So no cache flushing
necessary.

Sparc makes sure that shared mapping have consistent colors. Therefore
all that's left are private mappings and those will be initialized by
block stores to clear the page out or similar.
Also, when creating new mappings, we flush the D-cache when necessary
in update_mmu_cache().
We also maintain a bit in the page struct to track when a page which
was potentially written to on one cpu ends up mapped into another
address space and flush as necessary.
The cache is write-through, which simplifies the preconditions we have
to maintain.

Sparc's move_pte seems to be flushing the D-cache to prevent aliasing. It is
not modifying the PTE itself AFAICS:
#ifdef DCACHE_ALIASING_POSSIBLE
#define __HAVE_ARCH_MOVE_PTE
#define move_pte(pte, prot, old_addr, new_addr) \
({ \
pte_t newpte = (pte); \
if (tlb_type != hypervisor && pte_present(pte)) { \
unsigned long this_pfn = pte_pfn(pte); \
\
if (pfn_valid(this_pfn) && \
(((old_addr) ^ (new_addr)) & (1 << 13))) \
flush_dcache_page_all(current->mm, \
pfn_to_page(this_pfn)); \
} \
newpte; \
})
#endif
If its an issue, then how do transparent huge pages work on Sparc? I don't
see the huge page code (move_huge_pages) during mremap doing anything special
for Sparc architecture when moving PMDs..
Also, do we not flush the caches from any path when we munmap address space?
We do call do_munmap on the old mapping from mremap after moving to the new one.

Ah, true. Thanks. Couldn't test every arch obviously. The reason this was
missed is the script could not find matches with prototypes without named
parameters:
extern pgtable_t pte_alloc_one(struct mm_struct *, unsigned long);
I wrote something like this as below but it failed to compile, Julia any
suggestions on how to express this?
@pte_alloc_func_proto depends on patch exists@
type T1, T2, T3, T4;
identifier fn =~
"^(__pte_alloc|pte_alloc_one|pte_alloc|__pte_alloc_kernel|pte_alloc_one_kernel)$";
@@
(
- T3 fn(T1, T2);
+ T3 fn(T1);
|
- T3 fn(T1, T2, T4);
+ T3 fn(T1, T2);
)
thanks,

Ok, I can update the changelog with that information next time I send it.
This is the only thing I didn't mention in the changelog since it was a
trivial unused function deletion.. but I mentioned everything else..
And sir, you are one thorough reviewer! ;-)

Weird it seems working now. I could swear 5 minutes ago it wasn't and I did
give a unique rule name. Don't know what I missed.
Anyway, thank you for all the quick responses and the help!
