[PATCH v5 0/8] huge vmalloc mappings

[PATCH v5 0/8] huge vmalloc mappings

[Nicholas Piggin]

I made this powerpc-only for the time being. It shouldn't be too hard to
add support for other archs that define HUGE_VMAP. I have booted x86
with it enabled, just may not have audited everything.

Hi Andrew, would you care to put this in your tree?

Thanks,
Nick

Since v4:
- Fixed an off-by-page-order bug in v4
- Several minor cleanups.
- Added page order to /proc/vmallocinfo
- Added hugepage to alloc_large_system_hage output.
- Made an architecture config option, powerpc only for now.

Since v3:
- Fixed an off-by-one bug in a loop
- Fix !CONFIG_HAVE_ARCH_HUGE_VMAP build fail
- Hopefully this time fix the arm64 vmap stack bug, thanks Jonathan
  Cameron for debugging the cause of this (hopefully).

Since v2:
- Rebased on vmalloc cleanups, split series into simpler pieces.
- Fixed several compile errors and warnings
- Keep the page array and accounting in small page units because
  struct vm_struct is an interface (this should fix x86 vmap stack debug
  assert). [Thanks Zefan]

[PATCH v5 1/8] mm/vmalloc: fix vmalloc_to_page for huge vmap mappings

[Nicholas Piggin]

vmalloc_to_page returns NULL for addresses mapped by larger pages[*].
Whether or not a vmap is huge depends on the architecture details,
alignments, boot options, etc., which the caller can not be expected
to know. Therefore HUGE_VMAP is a regression for vmalloc_to_page.

This change teaches vmalloc_to_page about larger pages, and returns
the struct page that corresponds to the offset within the large page.
This makes the API agnostic to mapping implementation details.

[*] As explained by commit 029c54b095995 ("mm/vmalloc.c: huge-vmap:
    fail gracefully on unexpected huge vmap mappings")

Hmm, I wonder if that's WARN_ON_ONCE(pmd_bad(*pmd))), which would be

be there.

I'll try to reproduce and work out what's going on.

Thanks,
Nick

[PATCH v5 3/8] mm/vmalloc: rename vmap_*_range vmap_pages_*_range

[Nicholas Piggin]

The vmalloc mapper operates on a struct page * array rather than a
linear physical address, re-name it to make this distinction clear.

[PATCH v5 4/8] lib/ioremap: rename ioremap_*_range to vmap_*_range

[Nicholas Piggin]

This will be moved to mm/ and used as a generic kernel virtual mapping
function, so re-name it in preparation.

Same here.

[PATCH v5 5/8] mm: HUGE_VMAP arch support cleanup

[Nicholas Piggin]

This changes the awkward approach where architectures provide init
functions to determine which levels they can provide large mappings for,
to one where the arch is queried for each call.

This removes code and indirection, and allows constant-folding of dead
code for unsupported levels.

This also adds a prot argument to the arch query. This is unused
currently but could help with some architectures (e.g., some powerpc
processors can't map uncacheable memory with large pages).

Re: [PATCH v5 5/8] mm: HUGE_VMAP arch support cleanup

[Christophe Leroy]

Le 21/08/2020 à 06:44, Nicholas Piggin a écrit :

I think that in order to allow constant-folding of dead code for 
unsupported levels, you must define arch_vmap_xxx_supported() as static 
inline in a .h

If you have them in .c files, you'll get calls to tiny functions that 
will always return false, but will still be called and dead code won't 
be eliminated. And performance wise, that's probably not optimal either.

rewrite the changelog or remove it. Although this does get a step closer
at least.

linux/vmalloc.h includes asm/vmalloc.h
Should it go there ?

Please avoid the pointlessly long line.  And don't add the pointless
extern.

extern keyword is useless on function prototypes and deprecated. Please 
don't add new function prototypes with that keyword.

[PATCH v5 7/8] mm/vmalloc: add vmap_range_noflush variant

[Nicholas Piggin]

As a side-effect, the order of flush_cache_vmap() and
arch_sync_kernel_mappings() calls are switched, but that now matches
the other callers in this file.

[PATCH v5 8/8] mm/vmalloc: Hugepage vmalloc mappings

[Nicholas Piggin]

On platforms that define HAVE_ARCH_HUGE_VMAP and support PMD vmaps,
vmalloc will attempt to allocate PMD-sized pages first, before falling
back to small pages.

Allocations which use something other than PAGE_KERNEL protections are
not permitted to use huge pages yet, not all callers expect this (e.g.,
module allocations vs strict module rwx).

This reduces TLB misses by nearly 30x on a `git diff` workload on a
2-node POWER9 (59,800 -> 2,100) and reduces CPU cycles by 0.54%.

This can result in more internal fragmentation and memory overhead for a
given allocation, an option nohugevmalloc is added to disable at boot.

I like this series, but if I understand correctly it enables huge 
vmalloc mappings only for hugepages sizes matching a page directory 
levels, ie on a PPC32 it would work only for 4M hugepages.

On the 8xx, we only have 8M and 512k hugepages. Any change that it can 
support these as well one day ?

Yeah it really just uses the HUGE_VMAP mapping which is already there.

The vmap_range interface can now handle that, then adding support is the
main work. Either make it weak and arch can override it, or add some
arch helpers to make the generic version create the huge pages if it's
not too ugly. Then you get those large pages for ioremap for free.

The vmalloc part to allocate and try to map a bigger page size and use 
it is quite trivial to change from PMD to an arch specific size.

Thanks,
Nick
