/sys/devices/system/cpu/cpu<LCORE_NUM>/topology/physical_package_id

continue preparing map for other online lcores instead of returning with -1
for a first unavailable lcore.

Also, in SMT=off scenario for powerpc, lcore ids can not be always indexed from
0 upto 'number of cores present' (/sys/devices/system/cpu/present). For eg, for
an online lcore 32, core_id returned in sysfs is 112 where online lcores are
10 (as in one configuration), hence sysfs lcore id can not be checked with

contigmem: zero all pages during mmap

On Linux, all huge pages are zeroed by the kernel before
first access by the DPDK application.  But on FreeBSD,
the contigmem driver would only zero the contiguous
memory regions during initial driver load.

DPDK commit b78c91751 eliminated the explicit memset()
operation for rte_zmalloc(), which was OK on Linux
because the kernel zeroes the pages during app start,
but this broke FreeBSD when restarting app.
So this patch explicitly zeroes the pages before they are mmap'd,
to ensure equivalent behavior to Linux.

doc: announce vhost-cuse removal

Vhost-cuse was invented before vhost-user exist. The both are actually
doing the same thing: a vhost-net implementation in user space. But they
are not exactly the same thing.

Firstly, vhost-cuse is harder for use; no one seems to care it, either.
Furthermore, since v2.1, a large majority of development effort has gone
to vhost-user. For example, we extended the vhost-user spec to add the
multiple queue support. We also added the vhost-user live migration at
v16.04 and the latest one, vhost-user reconnect that allows vhost app
restart without restarting the guest. Both of them are very important
features for product usage and none of them works for vhost-cuse.

You now see that the difference between vhost-user and vhost-cuse is
big (and will be bigger and bigger as time moves forward), that you
should never use vhost-cuse, that we should drop it completely.

The remove would also result to a much cleaner code base, allowing us
to do all kinds of extending easier.

So here to mark vhost-cuse as deprecated in this release and will be
removed in the next release (v16.11).

8 years agodoc: announce ABI change for Tx preparation
Tomasz Kulasek [Thu, 21 Jul 2016 15:24:19 +0000 (17:24 +0200)]
doc: announce ABI change for Tx preparation

This is an ABI deprecation notice for DPDK 16.11 in librte_ether about
changes in rte_eth_dev and rte_eth_desc_lim structures.

As discussed in that thread:

http://dpdk.org/ml/archives/dev/2015-September/023603.html

Different NIC models depending on HW offload requested might impose
different requirements on packets to be TX-ed in terms of:

 - Max number of fragments per packet allowed
 - Max number of fragments per TSO segments
 - The way pseudo-header checksum should be pre-calculated
 - L3/L4 header fields filling
 - etc.

MOTIVATION:
-----------

1) Some work cannot (and didn't should) be done in rte_eth_tx_burst.
   However, this work is sometimes required, and now, it's an
   application issue.

2) Different hardware may have different requirements for TX offloads,
   other subset can be supported and so on.

3) Some parameters (eg. number of segments in ixgbe driver) may hung
   device. These parameters may be vary for different devices.

   For example i40e HW allows 8 fragments per packet, but that is after
   TSO segmentation. While ixgbe has a 38-fragment pre-TSO limit.

4) Fields in packet may require different initialization (like eg. will
   require pseudo-header checksum precalculation, sometimes in a
   different way depending on packet type, and so on). Now application
   needs to care about it.

5) Using additional API (rte_eth_tx_prep) before rte_eth_tx_burst let to
   prepare packet burst in acceptable form for specific device.

6) Some additional checks may be done in debug mode keeping tx_burst
   implementation clean.

PROPOSAL:
---------

To help user to deal with all these varieties we propose to:

1. Introduce rte_eth_tx_prep() function to do necessary preparations of
   packet burst to be safely transmitted on device for desired HW
   offloads (set/reset checksum field according to the hardware
   requirements) and check HW constraints (number of segments per
   packet, etc).

   While the limitations and requirements may differ for devices, it
   requires to extend rte_eth_dev structure with new function pointer
   "tx_pkt_prep" which can be implemented in the driver to prepare and
   verify packets, in devices specific way, before burst, what should to
   prevent application to send malformed packets.

2. Also new fields will be introduced in rte_eth_desc_lim:
   nb_seg_max and nb_mtu_seg_max, providing an information about max
   segments in TSO and non-TSO packets acceptable by device.

   This information is useful for application to not create/limit
   malicious packet.

APPLICATION (CASE OF USE):
--------------------------

1) Application should to initialize burst of packets to send, set
   required tx offload flags and required fields, like l2_len, l3_len,
   l4_len, and tso_segsz

2) Application passes burst to the rte_eth_tx_prep to check conditions
   required to send packets through the NIC.

3) The result of rte_eth_tx_prep can be used to send valid packets
   and/or restore invalid if function fails.

eg.

for (i = 0; i < nb_pkts; i++) {

/* initialize or process packet */

bufs[i]->tso_segsz = 800;
bufs[i]->ol_flags = PKT_TX_TCP_SEG | PKT_TX_IPV4
| PKT_TX_IP_CKSUM;
bufs[i]->l2_len = sizeof(struct ether_hdr);
bufs[i]->l3_len = sizeof(struct ipv4_hdr);
bufs[i]->l4_len = sizeof(struct tcp_hdr);
}

/* Prepare burst of TX packets */
nb_prep = rte_eth_tx_prep(port, 0, bufs, nb_pkts);

if (nb_prep < nb_pkts) {
printf("tx_prep failed\n");

/* drop or restore invalid packets */

}

/* Send burst of TX packets */
nb_tx = rte_eth_tx_burst(port, 0, bufs, nb_prep);

/* Free any unsent packets. */
