Subject: [PATCH 0/6] arm64/mm: Enable memory hot remove and ZONE_DEVICE
Date: Wed, 3 Apr 2019 10:00:00 +0530 [thread overview]
Message-ID: <1554265806-11501-1-git-send-email-anshuman.khandual@arm.com> (raw)
This series enables memory hot remove on arm64, fixes a memblock removal
ordering problem in generic __remove_memory(), enables sysfs memory probe
interface on arm64. It also enables ZONE_DEVICE with struct vmem_altmap
support.
Testing:
Tested hot remove on arm64 for all 4K, 16K, 64K page config options with
all possible VA_BITS and PGTABLE_LEVELS combinations. Tested ZONE_DEVICE
with ARM64_4K_PAGES through a dummy driver.
Build tested on non arm64 platforms. I will appreciate if folks can test
arch_remove_memory() re-ordering in __remove_memory() on other platforms.
Dependency:
V5 series in the thread (https://lkml.org/lkml/2019/2/14/1096) will make
kernel linear mapping loose pgtable_page_ctor() init. When this happens
the proposed functions free_pte|pmd|pud_table() in [PATCH 2/6] will have
to stop calling pgtable_page_dtor().
