outputting the results in either a human readable or raw, script parseable
format
Note that, in the case of dynamically linked applications, pmdinfo.py will
scan for implicitly linked PMDs by searching the specified binaries
.dynamic section for DT_NEEDED entries that contain the substring
librte_pmd. The DT_RUNPATH, LD_LIBRARY_PATH, /usr/lib and /lib are
searched for these libraries, in that order
If a file is specified with no path, it is assumed to be a PMD DSO, and the
LD_LIBRARY_PATH, /usr/lib[64]/ and /lib[64] is searched for it
Currently the tool can output data in 3 formats:
a) raw, suitable for scripting, where the raw JSON strings are dumped out
b) table format (default) where hex pci ids are dumped in a table format
c) pretty, where a user supplied pci.ids file is used to print out vendor

Modify the PMD_REGISTER_DRIVER macro, adding a name argument to it. The
addition of a name argument creates a token that can be used for subsequent
macros in the creation of unique symbol names to export additional bits of
information for use by the pmdinfogen tool. For example:
PMD_REGISTER_DRIVER(ena_driver, ena);
registers the ena_driver struct as it always did, and creates a symbol
const char this_pmd_name0[] __attribute__((used)) = "ena";
which pmdinfogen can search for and extract. The subsequent macro
DRIVER_REGISTER_PCI_TABLE(ena, ena_pci_id_map);
creates a symbol const char ena_pci_tbl_export[] __attribute__((used)) =
"ena_pci_id_map";
Which allows pmdinfogen to find the pci table of this driver
Using this pattern, we can export arbitrary bits of information.
pmdinfo uses this information to extract hardware support from an object
file and create a json string to make hardware support info discoverable

pmdinfogen is a tool used to parse object files and build json strings for
use in later determining hardware support in a dso or application binary.
pmdinfo looks for the non-exported symbol names this_pmd_name<n> and
this_pmd_tbl<n> (where n is a integer counter). It records the name of
each of these tuples, using the later to find the symbolic name of the
pci_table for physical devices that the object supports. With this
information, it outputs a C file with a single line of the form:
static char *<pmd_name>_driver_info[] __attribute__((used)) = " \
PMD_DRIVER_INFO=<json string>";
Where <pmd_name> is the arbitrary name of the pmd, and <json_string> is the
json encoded string that hold relevant pmd information, including the pmd
name, type and optional array of pci device/vendor ids that the driver
supports.
This c file is suitable for compiling to object code, then relocatably
linking into the parent file from which the C was generated. This creates
an entry in the string table of the object that can inform a later tool
about hardware support.

In such a case, the mempool ring simply cycles through all the mbufs,
resulting in a LLC miss on every mbuf allocated when the number of
mbufs is large. A stack (LIFO) recycles buffers more effectively in
this case.

This reverts commit 593a084afc.
Since recently [1], it is not possible to run the dpdk with
non-root privileges and the --no-huge option. This is because the eal
layer tries to lock the memory. Using locked memory is mandatory for
physical devices because they reference physical addresses.
But a user may want to start the dpdk without locked memory, because he
does not have the permission to do so, and/or does not have this need,
for instance because he uses virtual drivers.
So this commit reverts the use of MAP_LOCKED in mmap() flags.

Reported-by: Panu Matilainen <pmatilai@redhat.com>
Signed-off-by: Olivier Matz <olivier.matz@6wind.com>
EAL memory init allocates all free hugepages of the whole system,
which seen from sysfs, even when applications do not ask so many.
When there is a limitation on how many hugepages an application can
use (such as cgroup.hugetlb), or hugetlbfs is specified with an
option of size (exceeding the quota of the fs), it just fails to
start even there are enough hugepages allocated.
To fix above issue, this patch:
- Changes the logic to continue memory init to see if hugetlb
requirement of application can be addressed by already allocated
hugepages.
- To make sure each hugepage is allocated successfully, we add a
recover mechanism, which relies on a mem access to fault-in
hugepages, and if it fails with SIGBUS, recover to previously
saved stack environment with siglongjmp().
For the case of CONFIG_RTE_EAL_SINGLE_FILE_SEGMENTS (enabled by
default when compiling IVSHMEM target), it's indispensable to
mapp all free hugepages in the system. Under this case, it fails
to start when allocating fails.
Test example:
a. cgcreate -g hugetlb:/test-subgroup
b. cgset -r hugetlb.1GB.limit_in_bytes=2147483648 test-subgroup
c. cgexec -g hugetlb:test-subgroup \
