6 years agomem: support mapping hugepages at runtime
Anatoly Burakov [Wed, 11 Apr 2018 12:30:26 +0000 (13:30 +0100)]
mem: support mapping hugepages at runtime

Nothing uses this code yet. The bulk of it is copied from old
memory allocation code (linuxapp eal_memory.c). We provide an
EAL-internal API to allocate either one page or multiple pages,
guaranteeing that we'll get contiguous VA for all of the pages
that we requested.

Not supported on FreeBSD.

Locking is done via fcntl() because that way, when it comes to
taking out write locks or unlocking on deallocation, we don't
have to keep original fd's around. Plus, using fcntl() gives us
ability to lock parts of a file, which is useful for single-file
segments, which are coming down the line.

memzone: replace memzone array with fbarray

Since we have to allocate an fbarray for memzones, we have to do
it before we initialize memory subsystem, because that, in
secondary processes, will (later) allocate more fbarrays than the

6 years agomem: replace memseg with memseg lists
Anatoly Burakov [Wed, 11 Apr 2018 12:30:24 +0000 (13:30 +0100)]
mem: replace memseg with memseg lists

Before, we were aggregating multiple pages into one memseg, so the
number of memsegs was small. Now, each page gets its own memseg,
so the list of memsegs is huge. To accommodate the new memseg list
size and to keep the under-the-hood workings sane, the memseg list
is now not just a single list, but multiple lists. To be precise,
each hugepage size available on the system gets one or more memseg
lists, per socket.

In order to support dynamic memory allocation, we reserve all
memory in advance (unless we're in 32-bit legacy mode, in which
case we do not preallocate memory). As in, we do an anonymous
mmap() of the entire maximum size of memory per hugepage size, per
socket (which is limited to either RTE_MAX_MEMSEG_PER_TYPE pages or
RTE_MAX_MEM_MB_PER_TYPE megabytes worth of memory, whichever is the
smaller one), split over multiple lists (which are limited to
either RTE_MAX_MEMSEG_PER_LIST memsegs or RTE_MAX_MEM_MB_PER_LIST
megabytes per list, whichever is the smaller one). There is also
a global limit of CONFIG_RTE_MAX_MEM_MB megabytes, which is mainly
used for 32-bit targets to limit amounts of preallocated memory,
but can be used to place an upper limit on total amount of VA
memory that can be allocated by DPDK application.

So, for each hugepage size, we get (by default) up to 128G worth
of memory, per socket, split into chunks of up to 32G in size.
The address space is claimed at the start, in eal_common_memory.c.
The actual page allocation code is in eal_memalloc.c (Linux-only),
and largely consists of copied EAL memory init code.

Pages in the list are also indexed by address. That is, in order
to figure out where the page belongs, one can simply look at base
address for a memseg list. Similarly, figuring out IOVA address
of a memzone is a matter of finding the right memseg list, getting
offset and dividing by page size to get the appropriate memseg.

This commit also removes rte_eal_dump_physmem_layout() call,
according to deprecation notice [1], and removes that deprecation
notice as well.

On 32-bit targets due to limited VA space, DPDK will no longer
spread memory to different sockets like before. Instead, it will
(by default) allocate all of the memory on socket where master
lcore is. To override this behavior, --socket-mem must be used.

The rest of the changes are really ripple effects from the memseg
change - heap changes, compile fixes, and rewrites to support
fbarray-backed memseg lists. Due to earlier switch to _walk()
functions, most of the changes are simple fixes, however some
of the _walk() calls were switched to memseg list walk, where
it made sense to do so.

Additionally, we are also switching locks from flock() to fcntl().
Down the line, we will be introducing single-file segments option,
and we cannot use flock() locks to lock parts of the file. Therefore,
we will use fcntl() locks for legacy mem as well, in case someone is
unfortunate enough to accidentally start legacy mem primary process
alongside an already working non-legacy mem-based primary process.

6 years agoeal: add shared indexed file-backed array
Anatoly Burakov [Wed, 11 Apr 2018 12:30:23 +0000 (13:30 +0100)]
eal: add shared indexed file-backed array

rte_fbarray is a simple indexed array stored in shared memory
via mapping files into memory. Rationale for its existence is the
following: since we are going to map memory page-by-page, there
could be quite a lot of memory segments to keep track of (for
smaller page sizes, page count can easily reach thousands). We
can't really make page lists truly dynamic and infinitely expandable,
because that involves reallocating memory (which is a big no-no in
multiprocess). What we can do instead is have a maximum capacity as
something really, really large, and decide at allocation time how
big the array is going to be. We map the entire file into memory,
which makes it possible to use fbarray as shared memory, provided
the structure itself is allocated in shared memory. Per-fbarray
locking is also used to avoid index data races (but not contents
data races - that is up to user application to synchronize).

In addition, in understanding that we will frequently need to scan
this array for free space and iterating over array linearly can
become slow, rte_fbarray provides facilities to index array's
usage. The following use cases are covered:
 - find next free/used slot (useful either for adding new elements
   to fbarray, or walking the list)
 - find starting index for next N free/used slots (useful for when
   we want to allocate chunk of VA-contiguous memory composed of
   several pages)
 - find how many contiguous free/used slots there are, starting
   from specified index (useful for when we want to figure out
   how many pages we have until next hole in allocated memory, to
   speed up some bulk operations where we would otherwise have to
   walk the array and add pages one by one)

This is accomplished by storing a usage mask in-memory, right
after the data section of the array, and using some bit-level
magic to figure out the info we need.

eal: add legacy memory option

This adds a "--legacy-mem" command-line switch. It will be used to

allocate/free memory (the downside), but one where the user can
get physically contiguous memory, like before (the upside).

For now, nothing but the legacy behavior exists, non-legacy
memory init sequence will be added later. For FreeBSD, non-legacy
memory init will never be enabled, while for Linux, it is
disabled in this patch to avoid breaking bisect, but will be
enabled once non-legacy mode will be fully operational.

mempool: support new allocation methods

If a user has specified that the zone should have contiguous memory,
add a memzone flag to request contiguous memory. Otherwise, account
for the fact that unless we're in IOVA_AS_VA mode, we cannot
guarantee that the pages would be physically contiguous, so we
calculate the memzone size and alignments as if we were getting
the smallest page size available.

However, for the non-IOVA contiguous case, existing mempool size
calculation function doesn't give us expected results, because it
will return memzone sizes aligned to page size (e.g. a 1MB mempool
may use an entire 1GB page), therefore in cases where we weren't
specifically asked to reserve non-contiguous memory, first try
reserving a memzone as IOVA-contiguous, and if that fails, then
try reserving with page-aligned size/alignment.
