Users have the option to allocate hugepage memory by # of
pages or percent of memory available.
Percent allocation is allocated on boot.
Story: 2006755
Task: 37245
CLI:
Allocating by percentage:
system host-memory-modify -2M 50% controller-0 0
Allocating by # of pages
system host-memory-modify -2M 50 controller-0 0
Testcases:
Allocating hugepage memory by percentage
Allocating hugepage memory by number of pages
Correct percentage is allocated if available memory
changes
100% of hugepage memory allocates correctly
Check error is raised if user attempts to allocate
percentage not in range of 0%-100%
Confirm that Horizon GUI can set as both percent and
integer
Confirm that hugepage changes are made before unlock
and after unlock
