eal/windows: fix IOVA mode detection and handling

Windows EAL did not detect IOVA mode and worked incorrectly
if physical addresses could not be obtained
(if virt2phys driver was missing or inaccessible).
In this case, rte_mem_virt2iova() reported RTE_BAD_IOVA for any address.
Inability to obtain IOVA, be it PA or VA, should cause a failure
for the DPDK allocator, but it was hidden by the implementation,
so allocations did not fail when they should.
The mode when DPDK cannot obtain PA but can work is IOVA-as-VA mode.
However, rte_eal_iova_mode() always returned RTE_IOVA_DC
(while it should only ever return RTE_IOVA_PA or RTE_IOVA_VA),
because IOVA mode detection was not implemented.

Implement IOVA mode detection:
1. Always allow to force --iova-mode=va.
2. Allow to force --iova-mode=pa only if virt2phys is available.
3. If no mode is forced and virt2phys is available,
   select the mode according to bus requests, default to PA.
4. If no mode is forced but virt2phys is unavailable, default to VA.
Fix rte_mem_virt2iova() by returning VA when using IOVA-as-VA.
Fix rte_eal_iova_mode() by returning the selected mode.

The rte_lpm6 keeps routing information for control plane purpose

From the rte_jhash() documentation: If input key is not aligned to

the memory region just after may be read (but not used in the

rte_lpm6 uses 17 bytes keys consisting of IPv6 address (16 bytes) +
depth (1 byte).

This patch increases the size of the depth field up to uint32_t

In current DPDK framework, each Rx queue is pre-loaded with mbufs to
save incoming packets. For some PMDs, when number of representors scale
out in a switch domain, the memory consumption became significant.
Polling all ports also leads to high cache miss, high latency and low
throughput.

This patch introduces shared Rx queue. Ports in same Rx domain and
switch domain could share Rx queue set by specifying non-zero sharing
group in Rx queue configuration.

Shared Rx queue is identified by share_rxq field of Rx queue
configuration. Port A RxQ X can share RxQ with Port B RxQ Y by using
same shared Rx queue ID.

No special API is defined to receive packets from shared Rx queue.
Polling any member port of a shared Rx queue receives packets of that
queue for all member ports, port_id is identified by mbuf->port. PMD is
responsible to resolve shared Rx queue from device and queue data.

Shared Rx queue must be polled in same thread or core, polling a queue
ID of any member port is essentially same.

Multiple share groups are supported. PMD should support mixed
configuration by allowing multiple share groups and non-shared Rx queue
on one port.

Example grouping and polling model to reflect service priority:
 Group1, 2 shared Rx queues per port: PF, rep0, rep1
 Group2, 1 shared Rx queue per port: rep2, rep3, ... rep127
 Core0: poll PF queue0
 Core1: poll PF queue1
 Core2: poll rep2 queue0

PMD advertise shared Rx queue capability via RTE_ETH_DEV_CAPA_RXQ_SHARE.

2 years agovfio: allow partially unmapping adjacent memory
Xuan Ding [Mon, 11 Oct 2021 07:59:41 +0000 (07:59 +0000)]
vfio: allow partially unmapping adjacent memory

Currently, if we map a memory area A, then map a separate memory area B
that by coincidence happens to be adjacent to A, current implementation
will merge these two segments into one, and if partial unmapping is not
supported, these segments will then be only allowed to be unmapped in
one go. In other words, given segments A and B that are adjacent, it
is currently not possible to map A, then map B, then unmap A.

Fix this by adding a notion of "chunk size", which will allow
subdividing segments into equally sized segments whenever we are dealing
with an IOMMU that does not support partial unmapping. With this change,
we will still be able to merge adjacent segments, but only if they are
of the same size. If we keep with our above example, adjacent segments A
and B will be stored as separate segments if they are of different
sizes.
