|
sets the NUMA memory policy,

|

which consists of a policy mode and zero or more nodes,
|
2006-02-08 03:20:44 +00:00
|
|
|
for the memory range starting with

|
2007-08-27 10:48:50 +00:00

The memory policy defines from which node memory is allocated.

flag, pages will be allocated only according to the specified
|
2016-10-13 07:38:59 +00:00
|
|
|
policy when the application writes (stores) to the page.
|
2007-08-27 10:48:50 +00:00
|
|
|
For anonymous regions, an initial read access will use a shared
|
|
|
|
page in the kernel containing all zeros.
|
|
|
|
For a file mapped with
|
|
|
|
.BR MAP_PRIVATE ,
|
|
|
|
an initial read access will allocate pages according to the
|
2016-10-13 08:19:27 +00:00
|
|
|
memory policy of the thread that causes the page to be allocated.
|
|
|
|
This may not be the thread that called
|
2007-08-27 10:48:50 +00:00
|
|
|
.BR mbind ().
|
|
|
|
|
|
|
|
The specified policy will be ignored for any
|
|
|
|
.B MAP_SHARED
|
|
|
|
mappings in the specified memory range.
|
2016-10-13 08:19:27 +00:00
|
|
|
Rather the pages will be allocated according to the memory policy
|
|
|
|
of the thread that caused the page to be allocated.
|
|
|
|
Again, this may not be the thread that called
|
2007-08-27 10:48:50 +00:00
|
|
|
.BR mbind ().
|
|
|
|
|
|
|
|
If the specified memory range includes a shared memory region
|
|
|
|
created using the
|
|
|
|
.BR shmget (2)
|
|
|
|
system call and attached using the
|
|
|
|
.BR shmat (2)
|
|
|
|
system call,
|
|
|
|
pages allocated for the anonymous or shared memory region will
|
2016-10-13 06:45:15 +00:00
|
|
|
be allocated according to the policy specified, regardless of which
|
2007-08-27 10:48:50 +00:00
|
|
|
process attached to the shared memory segment causes the allocation.
|
|
|
|
If, however, the shared memory region was created with the
|
|
|
|
.B SHM_HUGETLB
|
|
|
|
flag,
|
|
|
|
the huge pages will be allocated according to the policy specified
|
2008-08-11 09:00:23 +00:00
|
|
|
only if the page allocation is caused by the process that calls
|
