c049304a95 env: add spdk_pci_device_unclaim()
spdk_pci_device_claim() could create a file on the
filesystem that couldn't be deleted programatically.
It could only be overwritten - e.g. by another spdk
instance - but this didn't really work if that
another instance had less privileges and hence no
access to the previous file.

This is exactly the case we're seeing on our CI when
running SPDK as non-root. In general it's a good idea
not to leave any leftover files, so now we'll delete
the pci claim file when the spdk process exits.

spdk_pci_device_claim() used to return a file descriptor
that could be simply closed to "un-claim" the device.
It'll now return only a return code. The fd will be
stored inside spdk_pci_device and will be closed either
when user calls the newly introduced spdk_pci_device_unclaim(),
or when the device is detached.

We'll still need to clean up those files somewhere in
our test scripts (probably ./setup.sh cleanup) to
clean up after crashed processes or so - but we don't
necessarily want to run such scripts inside the autotest
whenever a non-root spdk is about to be started.

1897943987 env: define minimum alignment for dma-able memory
DPDK defines the minimum alignment as "suitable for any
kind of variable (in the same manner as malloc())", but
internally the alignment is always rounded up to the
cache line size, even if the requested alignment is 0.

We would like to start relying on this behavior in FTL,
where lba maps are allocated using DMA-able memory and
are constantly looked up or modified by different threads.
By having the lba maps unaligned, we risk having those
threads pollute each other's cache lines.

Rather than enforcing this memory alignment in FTL, we
do it in spdk_*malloc directly. In general it makes
sense to have DMA-able memory always cache-line-size
aligned for the same reason as above.

81523d9dd2 env/dpdk: register VFIO hotremove callback
This is an attempt to fix device hotremove with VFIO.

A soft device hotremove request through sysfs [1] would
currently just block until the SPDK process manually
releases that device - e.g. upon an RPC request.

VFIO won't get unbound from the device untill userspace
releases all its resources. VFIO can signal a pending
hotremove request by kicking any file descriptor provided
by the userspace - and DPDK does provide such descriptor -
but SPDK does not listen on it.

DPDK does offer handy API to listen and in this patch
we make use of it inside our env/pci layer. Within
a DPDK callback we set an internal per-device hotremove
flag, which upper-layer SPDK drivers can poll with a new
env API - spdk_pci_device_is_removed().

The VFIO hotremove event will be sent to primary
processes only, so that's where we listen.

We make use of this new API in the NVMe hotplug poller,
which will process it just like any other supported
hotremove event.

Fixes #595
Fixes #690

[1] # echo 1 > /sys/bus/pci/devices/<bdf>/remove

55656fb19f env: deprecate phys_addr param in spdk_*malloc()
Historically, all memory returned from spdk_*malloc()
used to be physically contiguous, hence it could be
addressed by offsetting just a single physical address.

Since DPDK dynamic memory management came along, the
above is no longer true. Memory returned from spdk_*malloc()
doesn't have to be physically contiguous anymore. The
phys_addr returned from spdk_*malloc() only applies to
the beginning of the allocated buffer and user can't
possibly know how big that "beginning" is.

The phys_addr parameter in spdk_*malloc() is useless on
its own in most cases and only suggests that the returned
buffer is physically contiguous, which is wrong.

This information can be returned from spdk_vtophys(),
which is the only safe way to retrieve physical addresses.
That's why phys_addr param in spdk_*malloc() is now
deprecated.

8c4ed83b49 vtophys: add length parameter to the vtophys function

Currently, most of the spdk_vtophys() callers manually
detect physically noncontiguous buffers to split them

is a first step towards encapsulating most of that logic
in a single place - in spdk_vtophys() itself.

This patch doesn't change any functionality on its own,
it only extends the API.

2f36777194 pci: introduce pci hooks
Devices behind a VMD aren't visible directly on the PCI
bus. In order to support them, we'll need an additional
VMD driver that's going to enumerate the devices behind
it and hook those into the SPDK PCI layer.

We want those devices to be accessible with the same APIs
that are used to access physical PCI devices.

The physical devices are still created and managed by
DPDK, but additional devices can be now hooked externally.

The hook API slightly departs from how env layer worked
so far. Instead of keeping the generic hook functions
internal-only and adding per-driver (NVMe, I/OAT, Virtio)
public functions, this patch makes the generic hook API
public from the start. It accepts the device driver as
a parameter, which needs to be exposed now. That's why
spdk_pci_nvme_get_driver() is introduced. It's only the
NVMe driver that's exposed so far, but other drivers and
their attach APIs should eventually follow the same path.
The previous model really didn't scale well and there's
no need to stretch it further.

5d57386885 env_dpdk: spdk_mem_map_translate informs user of translation size.
This function will now check for whether or not a memory region is
contiguous accross 2MB map entries and return the total length of that
contiguous buffer up to the size specified by the user.

Also includes unittests
This series of changes is aimed at enabling spdk_mem_map_translate to
report back to the user the length of the valid mem_map up to the
function that requested the translation.
This will be useful when retrieving memory regions associated with I/O
buffers in NVMe-oF. For large I/O it will be possible that the buffer is
split over multiple MRs and the I/O will have to be split into multiple
SGLs.

d288c41242 env_dpdk: change behavior of spdk_mem_map_translate
The function now takes a pointer as it's last argument, and copies the
size of the memory region for which the translation is validinto that
pointer.
For now, that will always be 2MB. However that behavior can change in
the future.
