Hi,
As part of the ongoing rebase effort, the following configuration
options need to be reviewed.
As a reminder, the ARK configuration flow involves moving unreviewed
configuration options from the pending directory to the ark directory.
In the diff below, options are removed from the pending directory and
added to the ark hierarchy. The final options that need to be ACKed
are the files that are being added to the ark hierarchy.
If the value for a file that is added should be changed, please reply
with a better option.
CONFIG_ZSMALLOC_PGTABLE_MAPPING:
By default, zsmalloc uses a copy-based object mapping method to
access allocations that span two pages. However, if a particular
architecture (ex, ARM) performs VM mapping faster than copying,
then you should select this. This causes zsmalloc to use page table
mapping rather than copying for object mapping.
You can check speed with zsmalloc benchmark:
https://github.com/spartacus06/zsmapbench
Symbol: ZSMALLOC_PGTABLE_MAPPING [=n]
Type : bool
Defined at mm/Kconfig:708
Prompt: Use page table mapping to access object in zsmalloc
Depends on: ZSMALLOC [=y]=y
Location:
-> Memory Management options
-> Memory allocator for compressed pages (ZSMALLOC [=y])
