|
||||
Detail
|
||||
======
|
||||
|
||||
With the patch, McKernel does the followings for the test:
|
||||
(1) Align heap with the value passed via mcexec -h option
|
||||
(2) Map stack and .data with the page with the size of the value
|
||||
passed via mcexec -s option
|
||||
(3) Enable THP via shmget
|
||||
(5) Report large page allocations
|
||||
|
||||
Alignment of symbols in .data, .bss is done by using the modified
|
||||
linker scripts.
