hi, All,

we don't have enough knowledge to understand fully the discussion for this
patch, we saw "NACK" but there were more discussions later.
so below report is just FYI what we observed in our tests. thanks

Thanks for the report. It was nack'ed because of the change to smaps/maps
files in proc.

Hello,

kernel test robot noticed a 858.5% improvement of vm-scalability.throughput on:

patch subject: [PATCH] /dev/zero: make private mapping full anonymous mapping

testcase: vm-scalability
config: x86_64-rhel-9.4
compiler: gcc-12
test machine: 224 threads 4 sockets Intel(R) Xeon(R) Platinum 8380H CPU @ 2.90GHz (Cooper Lake) with 192G memory
parameters:

runtime: 300s
test: small-allocs

It seems this benchmark allocates huge amount of small areas (each area is
as big as 40K) by mmap'ing /dev/zero.

This patch makes /dev/zero mapping a full anonymous mapping, so the later
vma_link_file() is actually skipped, which needs acquire file rmap lock then
insert the mapping into file rmap tree. The below profiling also showed
this.
Quoted here so that we don't have to scroll down:

95.60 -95.2 0.42 ±113% perf-profile.children.cycles-pp.__mmap
94.14 -93.6 0.54 ±106% perf-profile.children.cycles-pp.__mmap_new_vma
93.79 -93.6 0.21 ±171% perf-profile.children.cycles-pp.vma_link_file
93.40 -93.4 0.00 perf-profile.children.cycles-pp.rwsem_down_write_slowpath
93.33 -93.3 0.00 perf-profile.children.cycles-pp.rwsem_optimistic_spin
93.44 -93.2 0.24 ±178% perf-profile.children.cycles-pp.down_write
94.55 -93.1 1.40 ± 51% perf-profile.children.cycles-pp.ksys_mmap_pgoff
94.25 -93.0 1.30 ± 59% perf-profile.children.cycles-pp.__mmap_region
92.91 -92.9 0.00 perf-profile.children.cycles-pp.osq_lock
94.45 -92.7 1.72 ± 34% perf-profile.children.cycles-pp.do_mmap
94.46 -92.6 1.83 ± 31% perf-profile.children.cycles-pp.vm_mmap_pgoff

It significantly speed up mmap for this benchmark and the rmap lock
contention is reduced significantly for both multi-processes and
multi-threads.

The benchmark itself may exaggerate the improvement, but it may really speed
up some real life workloads. For example, multiple applications which may
allocate anonymous mapping by mmap'ing /dev/zero, then they may have
contention on /dev/zero's rmap lock.

It doesn't make too much sense to link /dev/zero anonymous vmas to the file
rmap tree. So the below patch should be able to speed up the benchmark too.

sorry for late and thanks a lot for information!

Oliver, can you please give this patch a try?

it seems this is an alternative patch?

Yes

since we applied your "/dev/zero: make private mapping full anonymous mapping"
patch upon a68d3cbfad like below:

* 7143ee2391f1e /dev/zero: make private mapping full anonymous mapping
* a68d3cbfade64 memstick: core: fix kernel-doc notation

so I applied below patch also upon a68d3cbfad.

we saw big improvement but not that big.

full comparison as below [1] just FYI.

Thanks for the update. I stared at the profiling report for a whole day, but I didn't figure out where that 400% lost. I just saw the number of page faults was fewer. And it seems like the reduction of page faults match the 400% loss. So I did more trace and profiling.

The test case did the below stuff in a tight loop:
mmap 40K memory from /dev/zero (read only)
read the area

So two major factors to the performance: mmap and page fault. The alternative patch did reduce the overhead of mmap to the same level as the original patch.

The further perf profiling showed the cost of page fault is higher than the original patch. But the profiling of page fault was interesting:

-   44.87%     0.01% usemem [kernel.kallsyms]                   [k] do_translation_fault
   - 44.86% do_translation_fault
      - 44.83% do_page_fault
         - 44.53% handle_mm_fault
              9.04% __handle_mm_fault

Page fault consumed 40% of cpu time in handle_mm_fault, but __handle_mm_fault just consumed 9%, I expected it should be the major consumer.

So I annotated handle_mm_fault, then found the most time was consumed by lru_gen_enter_fault() -> vma_has_recency() (my kernel has multi-gen LRU enabled):

      │     if (vma->vm_file && (vma->vm_file->f_mode & FMODE_NOREUSE))
       │     ↓ cbz     x1, b4
0.00 │       ldr     w0, [x1, #12]
99.59 │       eor     x0, x0, #0x800000
0.00 │       ubfx    w0, w0, #23, #1
       │     current->in_lru_fault = vma_has_recency(vma);
0.00 │ b4:   ldrh    w1, [x2, #1992]
0.01 │       bfi     w1, w0, #5, #1
0.00 │       strh    w1, [x2, #1992]

vma_has_recency() read vma->vm_file->f_mode if vma->vm_file is not NULL. But that load took a long time. So I inspected struct file and saw:

struct file {
    file_ref_t            f_ref;
    spinlock_t            f_lock;
    fmode_t                f_mode;
    const struct file_operations    *f_op;
    ...
}

The f_mode is in the same cache line with f_ref (my kernel does NOT have spin lock debug enabled). The test case mmap /dev/zero in a tight loop, so the refcount is modified (fget/fput) very frequently, this resulted in somehow false sharing.

So I tried the below patch on top of the alternative patch:

diff --git a/include/linux/mm_inline.h b/include/linux/mm_inline.h

+
        if (vma->vm_file && (vma->vm_file->f_mode & FMODE_NOREUSE))
                return false;

This made the profiling of page fault look normal:

                        - 1.90% do_translation_fault
                           - 1.87% do_page_fault

                                 - 1.36% __handle_mm_fault

Please try this in your test.

But AFAICT I have never seen performance issue reported due to the false sharing of refcount and other fields in struct file. This benchmark stressed this quite badly.

Because /dev/zero's private mapping is an anonymous mapping with valid
vm_file, so we need to bail out early if the vma is anonymous even though it
has vm_file. IMHO, making /dev/zero private mapping a full anonymous mapping
looks more clean.
