xenvirt was unbuildable as of commit
4c39baf297d10c217e7d3e7370f26a1fede58308..
That commit neglected to include the rte_vdev.h header, so several structs were
left undefined. This patch includes a fix for that as well.
Also, The linkage for xenvirt is broken in much the same way pmd_ring was, in
that the xenvirt pmd has a function that is called directly from applications
(the example being the testpmd application). The function is
rte_mempool_gntalloc_create, and should clearly be moved into the rte_mempool
library, with the supporting code in the function implementation moved to a new
xenvirt library separate from the pmd. This is a large undertaking that
detracts from the purpose of this series however, and so for now, I'm leaving
the linkage to the application in place, and will address this issue in a later
series

when building DSO's and must specify its use on the command line with the -d

Note that the ring driver was also written in such a way that it violated some
general layering principles, several functions were contained in the pmd which
were being called by example from the test application in the app/test
directory. Specifically it was calling eth_ring_pair_attach,
eth_ring_pair_create and rte_eth_ring_devinit, which should only be called
internally to the dpdk core library. To correct this I've removed those
functions, and instead allowed them to be called indirectly at initalization
time using the vdev command line argument key nodeaction=<name>:<node>:<action>
where action is one of ATTACH or CREATE. I've tested out the functionality of
the command line with the testpmd utility, with success, and have removed the
called functions from the test utility. This will affect how the test utility
is invoked (the -d and --vdev option will need to be specified on the command
line now), but honestly, given the way it was coded, I think the testing of the
ring pmd was not the best example of how to code with dpdk to begin with. I
have also left the two layer violating functions in place, so as not to break
existing applications, but added deprecation warnings to them so that apps can
migrate off them.

app/testpmd: add engine that replies to ARP and ICMP echo requests
Add a new specific packet processing engine in the "testpmd" application that
only replies to ARP requests and to ICMP echo requests.
For this purpose, a new "icmpecho" forwarding mode is provided that can be
dynamically selected with the following testpmd command:
set fwd icmpecho
before starting the receipt of packets on the selected ports.
Then, the "icmpecho" engine performs the following actions on all received
packets:
- replies to a received ARP request by sending back on the RX port a ARP
reply with a "sender hardware address" field containing the MAC address
of the RX port,
- replies to a ICMP echo request by sending back on the RX port a ICMP echo
reply, swapping the IP source and the IP destination address in the IP
header,
- otherwise, simply drops the received packet.
When replying to a received packet that was encapsulated into a VLAN tunnel,
the reply is sent back with the same VLAN identifier.
By default, the testpmd configures VLAN header stripping RX option on each
port.
This option is not managed by the icmpecho engine which won't detect
packets that were encapsulated into a VLAN.
To address this issue, the VLAN header stripping option must be previously
switched off with the following testpmd command:
vlan set strip off
When the "verbose" mode has been set with the testpmd command
"set verbose 1", the "icmpecho" engine displays informations about each
received packet.
The "icmpecho" forwarding engine can also be used to simply check port
connectivity at the hardware level (check that cables are well-plugged)
and at the software level (receipt of VLAN packets, for instance).

mem: remove redundant check in optimize_object_size
The second condition of this logical OR:
(get_gcd(new_obj_size, nrank * nchan) != 1 ||
get_gcd(nchan, new_obj_size) != 1)
is redundant with the first condition.
We can show that the first condition is equivalent to its disjunction
with the second condition using these two results:
- R1: For all conditions A and B, if B implies A, then (A || B) is
equivalent to A.
- R2: (get_gcd(nchan, new_obj_size) != 1) implies
(get_gcd(new_obj_size, nrank * nchan) != 1)
We can show R1 with the following truth table (0 is false, 1 is true):
+-----+-----++----------+-----+-------------+
| A | B || (A || B) | A | B implies A |
+-----+-----++----------+-----+-------------+
| 0 | 0 || 0 | 0 | 1 |
| 0 | 1 || 1 | 0 | 0 |
| 1 | 0 || 1 | 1 | 1 |
| 1 | 1 || 1 | 1 | 1 |
+-----+-----++----------+-----+-------------+
Truth table of (A || B) and A
We can show R2 by looking at the code of optimize_object_size and
get_gcd.
We see that:
- S1: (nchan >= 1) and (nrank >= 1).
- S2: get_gcd returns 0 only when both arguments are 0.
Let:
- X be get_gcd(new_obj_size, nrank * nchan).
- Y be get_gcd(nchan, new_obj_size).
Suppose:
- H1: get_gcd returns the greatest common divisor of its arguments.
- H2: (nrank * nchan) does not exceed UINT_MAX.
We prove (Y != 1) implies (X != 1) with the following steps:
- Suppose L0: (Y != 1). We have to show (X != 1).
- By H1, Y is the greatest common divisor of nchan and new_obj_size.
In particular, we have L1: Y divides nchan and new_obj_size.
- By H2, we have L2: nchan divides (nrank * nchan)
- By L1 and L2, we have L3: Y divides (nrank * nchan) and
new_obj_size.
- By H1 and L3, we have L4: (Y <= X).
- By S1 and S2, we have L5: (Y != 0).

mem: change default per socket memory allocation
Currently, if there is more memory in hugepages than the amount
requested by dpdk application, the memory is allocated by taking as much
memory as possible from each socket, starting from first one.
For example if a system is configured with 8 GB in 2 sockets (4 GB per
socket), and dpdk is requesting only 4GB of memory, all memory will be
taken in socket 0 (that have exactly 4GB of free hugepages) even if some
cores are configured on socket 1, and there are free hugepages on socket
1...
Change this behaviour to allocate memory on all sockets where some cores
are configured, spreading the memory amongst sockets using following
ratio per socket:
N° of cores configured on the socket / Total number of configured cores
* requested memory
If this new algorithm fails, it defaults to previous behaviour.
This algorithm is used when memory amount is specified globally using
-m option. Per socket memory allocation can always be done using
--socket-mem option.
It is implemented only for Linux as BSD part looks not to be ready for NUMA.

Instead of having a list of virtual device drivers in EAL code, add an
API to register drivers. Thanks to this new registration method, we can

This also enables the ability to register a virtual device driver as

The registration is done in an init function flaged with

devargs: use devargs for vdev and PCI whitelist/blacklist
Remove old whitelist code:
- remove references to rte_pmd_ring, rte_pmd_pcap and pmd_xenvirt in
is_valid_wl_entry() as we want to be able to register external virtual
drivers as a shared library. Moreover this code was duplicated with
dev_types[] from eal_common_pci.c
- eal_common_whitelist.c was badly named: it was able to process PCI
devices white list and the registration of virtual devices
- the parsing code was complex: all arguments were prepended in
one string dev_list_str[4096], then split again
Use the newly introduced rte_devargs to get:
- the PCI white list
- the PCI black list
- the list of virtual devices
Rework the tests:
- a part of the whitelist test can be removed as it is now tested
in app/test/test_devargs.c
- the other parts are just reworked to adapt them to the new API
This commit induce a small API modification: it is not possible to specify
several devices per "--use-device" option. This notation was anyway a bit
cryptic. Ex:
--use-device="eth_ring0,eth_pcap0;iface=ixgbe0"
now becomes:
--use-device="eth_ring0" --use-device="eth_pcap0;iface=ixgbe0"

instanciate virtual drivers, which was not possible before this patch.

timer: fix TSC frequency by not reading /proc/cpuinfo
This reverts commit
da6fd0759cbeb5fc14991a79e40105b9f6b99059.
"timer: get TSC frequency from /proc/cpuinfo"
The use of cpuinfo to determine the frequency of the TSC is not
advisable and leads to incorrect results when power management is
in use. This is because, while the TSC frequency does not change
in modern cpus with constant_tsc support, the frequency of the core,
and hence the frequency of the core reported by cpuinfo *does* change.
Depending on the current frequency of core 0 when an application is
started, the EAL can get a wildly incorrect value for the TSC freq.
Since frequency is scaled down for power saving, any incorrect value
is likely to be lower than the default, which means that any delay
loops inside the code which rely on the TSC will be shorter than
planned. This can cause issues (reported on the mailing list by a number
of people) where ports are not initialized correctly due to delays being
too short.
