Subject: [PATCH mm-unstable 0/9] continue hugetlb folio conversions
Date: Tue, 3 Jan 2023 13:13:32 -0600 [thread overview]
Message-ID: <20230103191340.116536-1-sidhartha.kumar@oracle.com> (raw)
============== OVERVIEW ===========================
This series continues the conversion of core hugetlb functions to use
folios. This series converts many helper funtions in the hugetlb fault
path. This is in preperation for another series to convert the hugetlb
fault code paths to operate on folios.
============== TESTING ===========================
LTP:
Ran 10 back to back rounds of the LTP hugetlb test suite.
Gigantic Huge Pages:
Test allocation and freeing via hugeadm commands:
hugeadm --pool-pages-min 1GB:10
hugeadm --pool-pages-min 1GB:0
Demote:
Demote 1 1GB hugepages to 512 2MB hugepages
echo 1 > /sys/kernel/mm/hugepages/hugepages-1048576kB/nr_hugepages
echo 1 > /sys/kernel/mm/hugepages/hugepages-1048576kB/demote
cat /sys/kernel/mm/hugepages/hugepages-2048kB/nr_hugepages
# 512
cat /sys/kernel/mm/hugepages/hugepages-1048576kB/nr_hugepages
# 0
