Title:
[Feature] Crystal Ridge-Restrict DAX to configurations with struct
page
Status in intel:
Triaged
Status in linux package in Ubuntu:
Triaged
Status in linux source package in Bionic:
Triaged
Bug description:
Description:
Several things break in surprising ways without the
"memorypageallocation" property. It's better to assume that DAX is
broken/unavailable in that configuration rather than try to explain
all the corner cases where operations with a DAX mapping will fail.
Disabling DAX support altogether if the pages are not allocated, DAX
is mostly unusable without pages.
