Subject: [PATCH v7 00/11] Speedup mremap on ppc64
Date: Mon, 7 Jun 2021 11:21:20 +0530 [thread overview]
Message-ID: <20210607055131.156184-1-aneesh.kumar@linux.ibm.com> (raw)
This patchset enables MOVE_PMD/MOVE_PUD support on power. This requires
the platform to support updating higher-level page tables without
updating page table entries. This also needs to invalidate the Page Walk
Cache on architecture supporting the same.
Changes from v6:
* Update ppc64 flush_tlb_range to invalidate page walk cache.
* Add patches to fix race between mremap and page out
* Add patch to fix build error with page table levels 2
Changes from v5:
* Drop patch mm/mremap: Move TLB flush outside page table lock
* Add fixes for race between optimized mremap and page out
Changes from v4:
* Change function name and arguments based on review feedback.
Changes from v3:
* Fix build error reported by kernel test robot
* Address review feedback.
Changes from v2:
* switch from using mmu_gather to flush_pte_tlb_pwc_range()
Changes from v1:
* Rebase to recent upstream
* Fix build issues with tlb_gather_mmu changes
Aneesh Kumar K.V (11):
mm/mremap: Fix race between MOVE_PMD mremap and pageout
mm/mremap: Fix race between MOVE_PUD mremap and pageout
selftest/mremap_test: Update the test to handle pagesize other than 4K
selftest/mremap_test: Avoid crash with static build
mm/mremap: Convert huge PUD move to separate helper
mm/mremap: Don't enable optimized PUD move if page table levels is 2
mm/mremap: Use pmd/pud_poplulate to update page table entries
powerpc/mm/book3s64: Fix possible build error
mm/mremap: Allow arch runtime override
powerpc/book3s64/mm: Update flush_tlb_range to flush page walk cache
powerpc/mm: Enable HAVE_MOVE_PMD support
