Acked-by: Jerin Jacob <jerinj@marvell.com>
Currently there are some public headers that include 'sys/queue.h', which
is not POSIX, but usually provided by the Linux/BSD system library.
(Not in POSIX.1, POSIX.1-2001, or POSIX.1-2008. Present on the BSDs.)
The file is missing on Windows. During the Windows build, DPDK uses a
bundled copy, so building a DPDK library works fine. But when OVS or other
applications use DPDK as a library, because some DPDK public headers
include 'sys/queue.h', on Windows, it triggers an error due to no such
file.
One solution is to install the 'lib/eal/windows/include/sys/queue.h' into
Windows environment, such as [1]. However, this means DPDK exports the
functionalities of 'sys/queue.h' into the environment, which might cause
symbols, macros, headers clashing with other applications.
The patch fixes it by removing the "#include <sys/queue.h>" from
DPDK public headers, so programs including DPDK headers don't depend
on the system to provide 'sys/queue.h'. When these public headers use
macros such as TAILQ_xxx, we replace it by the ones with RTE_ prefix.
For Windows, we copy the definitions from <sys/queue.h> to rte_os.h
in Windows EAL. Note that these RTE_ macros are compatible with
<sys/queue.h>, both at the level of API (to use with <sys/queue.h>
macros in C files) and ABI (to avoid breaking it).
Additionally, the TAILQ_FOREACH_SAFE is not part of <sys/queue.h>,
the patch replaces it with RTE_TAILQ_FOREACH_SAFE.

If after a bus scan, there are no devices using a particular bus, then
that bus should not be taken into account when deciding whether DPDK
should be run in VA or PA addressing mode. This becomes an issue when
the DSA bus driver code is used on a system without an IOMMU. The PCI
bus correctly reports that it only works in PA mode, while the DSA bus -
also correctly - reports that it works only in VA mode. The difference
is that there will be no devices found in a scan for the DSA bus, since
the kernel driver can only present those to userspace in the presence of
an IOMMU.
While we could change DSA instance to always report that it does not
care about the addressing mode, this would imply that it could be used
with DPDK in PA mode which is not the case. Therefore, this patch
changes the driver to report DC (don't care) in the case where no
devices are present, and VA otherwise.
NOTE: this addressing mode use of VA-only applies only in the case of
using DSA through the idxd kernel driver. The use of DSA though vfio-pci
is unaffected and works as with other PCI devices.

The device name format used in ifpga_rawdev_create() was changed to
"IFPGA:%02x:%02x.%x", but the format used in ifpga_rawdev_destroy()
was left as "IFPGA:%x:%02x.%x", it should be changed synchronously.
To prevent further similar errors, macro "IFPGA_RAWDEV_NAME_FMT" is
defined to replace this format string.

Add improved error handling to rte_ioat_completed_ops(). This patch adds
new parameters to the function to enable the user to track the completion
status of each individual operation in a batch. With this addition, the
function can help the user to determine firstly, how many operations may
have failed or been skipped and then secondly, which specific operations
did not complete successfully.

Add a new API to query remaining descriptor ring capacity. This API is
useful, for example, when an application needs to enqueue a fragmented
packet and wants to ensure that all segments of the packet will be enqueued
together.

The ring management in the idxd part of the driver is more complex than
it needs to be, tracking individual batches in a ring and having null
descriptors as padding to avoid having single-operation batches. This can
be simplified by using a regular ring-based layout, with additional
overflow at the end to ensure that the one does not need to wrap within a
batch.

Split the rte_ioat_rawdev_fns.h file into two separate headers, so that
the data structures for the original ioat devices and the newer idxd
ones can be kept separate from each other. This makes code management
and rework easier.

Rather than using a vdev with args, DPDK can scan and initialize the
devices automatically using a bus-type driver. This bus does not need to
worry about registering device drivers, rather it can initialize the
devices directly on probe.
The device instances (queues) to use are detected from /dev with the
additional info about them got from /sys.

Add a "--name-prefix" parameter to the quick configuration script for
DSA. This allows the queues configured on a DSA instance to be made
available to only one DPDK process in a setup with multiple DPDK process
instances.

The dpdk_idxd_cfg.py script included with the driver for convenience did
not work properly where the number of queues to be configured was
less than the number of groups or engines. This was because there would
be configured groups/engines not assigned to queues. Fix this by
limiting the engine and group counts to be no bigger than the number of
queues.

Although it's unused by the driver, add the interrupt handle field in
the descriptor to the descriptor structure for completeness, and
explicitly add the reserved padding field on the end of the structure
too. This means that when a descriptor is defined on the stack, or
initialized by the compiler, the unused/reserved space will be zeroed
appropriately.

Ensure all lists of drivers are standardized:
* one driver per line
* lists double-indented with spaces (as they are line continuations)
* elements in alphabetical order
* opening and closing list brackets "[" & "]" on own lines
* last element has trailing comma
Any code snippets in the list files is adjusted to single-indent using
whitespace to correspond to the new style also.
The lists of standard library dependencies per class, and other short
lists are not formatted one-per-line as these lists are not expected to
grow beyond 2 or 3 entries.
