[patch V2 00/10] x86/mm/cpa: Improve large page preservation handling

[patch V2 00/10] x86/mm/cpa: Improve large page preservation handling

[Thomas Gleixner]

Bin reported that try_preserve_large_page() in the page attribute code
consumes an large amount of CPU time. His initial attempts of addressing
this made me look deeper into the code.

The logic in this code is not really intelligent. It requires to check a
large page in 4k steps for conflicts. That's insane as most operations do
not conflict at all.

The code also lacks sanity checks which allow to detect whether the
existing mapping is incorrect vs. the static protections.

Any form of debugging or statistics is missing as well.

The following series addresses this:

  - Clean up the code so it becomes extensible

  - Provide the ability to check a full range for conflicts

  - Add debug output and statistics to quantify the changes and to allow
    observation of the mechanism in the future.

  - Add a sanity check for existing mappings with a fixup for the 2M case
    and a warning for the 1G case. The 2M case is trivial to address, the
    1G case requires larger changes and is just warned about for now.

  - Avoid conflict checks for operations which clear the PRESENT bit

  - Utilize the range checks to detect conflicts in one operation

  - Drop the 4k wise checking which turned out to provide no extra large
    page preservation in testing. There might be corner cases where a page
    would be preserved, but that's overkill for the common cases.

Before:
 1G pages checked:                    2
 1G pages sameprot:                   0
 1G pages preserved:                  0
 2M pages checked:                  540
 2M pages sameprot:                 466
 2M pages preserved:                 47
 4K pages checked:               800770
 4K pages set-checked:             7668

After:
 1G pages checked:                    2
 1G pages sameprot:                   0
 1G pages preserved:                  0
 2M pages checked:                  538
 2M pages sameprot:                 466
 2M pages preserved:                 47
 4K pages set-checked:             7668

This gets rid of ~800000 checks whether a particular address is with a
static protection region. Each check tests against 4 different regions,
which adds up to several million instructions.

Changes since V1: Fix patch 1/10 extra argument issue which breaks
	      	  bisectability.

Thanks,

	tglx

[patch V2 01/10] x86/mm/cpa: Split, rename and clean up try_preserve_large_page()

[Thomas Gleixner]

[-- Attachment #1: x86-mm-cpa--Split-try_preserve_large_page--.patch --]
[-- Type: text/plain, Size: 7653 bytes --]

Avoid the extra variable and gotos by splitting the function into the
actual algorithm and a callable function which contains the lock
protection.

Rename it to should_split_large_page() while at it so the return values make
actually sense.

Clean up the code flow, comments and general whitespace damage while at it. No
functional change.

[patch V2 02/10] x86/mm/cpa: Rework static_protections()

[Thomas Gleixner]

[-- Attachment #1: x86-mm-cpa--Rework-static_protections--.patch --]
[-- Type: text/plain, Size: 6924 bytes --]

static_protections() is pretty unreadable. Split it up into separate checks
for each protection area.

[patch V2 03/10] x86/mm/cpa: Allow range check for static protections

[Thomas Gleixner]

[-- Attachment #1: x86-mm-cpa--Allow-range-check-for-static-protections.patch --]
[-- Type: text/plain, Size: 6307 bytes --]

Checking static protections only page by page is slow especially for huge
pages. To allow quick checks over a complete range, add the ability to do
that.

Make the checks inclusive so the ranges can be directly used for debug output
later.

No functional change.

[patch V2 04/10] x86/mm/cpa: Add debug mechanism

[Thomas Gleixner]

[-- Attachment #1: x86-mm-cpa--Add-proper-debug-output.patch --]
[-- Type: text/plain, Size: 4135 bytes --]

The whole static protection magic is silently fixing up anything which is
handed in. That's just wrong. The offending call sites need to be fixed.

Add a debug mechanism which emits a warning if a requested mapping needs to be
fixed up. The DETECT debug mechanism is really not meant to be enabled except
for developers, so limit the output hard to the protection fixups.

[patch V2 05/10] x86/mm/cpa: Add large page preservation statistics

[Thomas Gleixner]

[-- Attachment #1: x86-mm-cpa--Add-large-page-preservation-statistics.patch --]
[-- Type: text/plain, Size: 5338 bytes --]

The large page preservation mechanism is just magic and provides no
information at all. Add optional statistic output in debugfs so the magic can
be evaluated. Defaults is off.

Output:

 1G pages checked:                    2
 1G pages sameprot:                   0
 1G pages preserved:                  0
 2M pages checked:                  540
 2M pages sameprot:                 466
 2M pages preserved:                 47

[patch V2 07/10] x86/mm/cpa: Add sanity check for existing mappings

[Thomas Gleixner]

[-- Attachment #1: x86-mm-cpa--Add-sanity-check-for-existing-mappings.patch --]
[-- Type: text/plain, Size: 5446 bytes --]

With the range check it is possible to do a quick verification that the
current mapping is correct vs. the static protection areas.

In case a incorrect mapping is detected a warning is emitted and the large
page is split up. If the large page is a 2M page, then the split code is
forced to check the static protections for the PTE entries to fix up the
incorrectness. For 1G pages this can't be done easily because that would
require to either find the offending 2M areas before the split or
afterwards. For now just warn about that case and revisit it when reported.

[patch V2 08/10] x86/mm/cpa: Optimize same protection check

[Thomas Gleixner]

[-- Type: text/plain, Size: 1959 bytes --]

When the existing mapping is correct and the new requested page protections
are the same as the existing ones, then further checks can be omitted and the
large page can be preserved. The slow path 4k wise check will not come up with
a different result.

Before:

 1G pages checked:                    2
 1G pages sameprot:                   0
 1G pages preserved:                  0
 2M pages checked:                  540

[patch V2 09/10] x86/mm/cpa: Do the range check early

[Thomas Gleixner]

[-- Attachment #1: x86-mm-cpa--Do-the-range-check-early.patch --]
[-- Type: text/plain, Size: 2931 bytes --]

To avoid excessive 4k wise checks in the common case do a quick check first
whether the requested new page protections conflict with a static
protection area in the large page. If there is no conflict then the
decision whether to preserve or to split the page can be made immediately.

If the requested range covers the full large page, preserve it. Otherwise
split it up. No point in doing a slow crawl in 4k steps.

Before:

 1G pages checked:                    2
 1G pages sameprot:                   0

[patch V2 10/10] x86/mm/cpa: Avoid the 4k pages check completely

[Thomas Gleixner]

[-- Attachment #1: x86-mm-cpa--Avoid-the-4k-pages-check-completely.patch --]
[-- Type: text/plain, Size: 5632 bytes --]

The extra loop which tries hard to preserve large pages in case of conflicts
with static protection regions turns out to be not preserving anything, at
least not in the experiments which have been conducted.

There might be corner cases in which the code would be able to preserve a
large page oaccsionally, but it's really not worth the extra code and the
cycles wasted in the common case.

[patch V3 04/10] x86/mm/cpa: Add debug mechanism

[Thomas Gleixner]

The whole static protection magic is silently fixing up anything which is
handed in. That's just wrong. The offending call sites need to be fixed.

Add a debug mechanism which emits a warning if a requested mapping needs to be
fixed up. The DETECT debug mechanism is really not meant to be enabled except
for developers, so limit the output hard to the protection fixups.

That's caused by 32bit mark_rodata_ro() doing:

       set_ro(kernel_text)
       kernel_set_to_readonly = 1;
       set_ro(rodata);

kernel_set_to_readonly enables the protection mechanism in CPA and
consequently triggers the WARN_ON() telling that the existing PTE/PMD is
incorrect vs. static protections.

64bit does not trigger this because it makes kernel text and rodata
readonly in one go. There is no real reasons not to do so on 32bit, so the
fix is obvious.

Thanks,

	tglx
