2018-11-12devargs: do not replace already inserted deviceThomas Monjalon
The devargs of a device can be replaced by a newly allocated one when trying to probe again the same device (multi-process or multi-ports scenarios). This is breaking some pointer references. It can be avoided by copying the new content, freeing the new devargs, and returning the already inserted pointer.

2018-10-28bus/pci: use IOVA DMA mask check when setting IOVA modeAlejandro Lucero
Currently the code precludes IOVA mode if IOMMU hardware reports less addressing bits than necessary for full virtual memory range. Although VT-d emulation currently only supports 39 bits, it could be iovas for allocated memlory being within that supported range. This patch allows IOVA mode in such a case adding a call to rte_eal_check_dma_mask using the reported addressing bits by the IOMMU hardware. Indeed, memory initialization code has been modified for using lower virtual addresses than those used by the kernel for 64 bits processes by default, and therefore memsegs iovas can use 39 bits or less for most systems. And this is likely 100% true for VMs. Signed-off-by: Alejandro Lucero <alejandro.lucero@netronome.com> Acked-by: Anatoly Burakov <anatoly.burakov@intel.com>

2018-10-19devargs: fix freeing during device removalThomas Monjalon
After calling unplug function of a bus, the device is expected to be freed. It is too late for getting devargs to remove. Anyway, the buses which implement unplug are already freeing the devargs, except the PCI bus. So the call to rte_devargs_remove() is removed from EAL and added in PCI.

2018-10-18eal: allow probing a device againThomas Monjalon
In the devargs syntax for device representors, it is possible to add several devices at once: -w dbdf,representor=[0-3] It will become a more frequent case when introducing wildcards and ranges in the new devargs syntax. If a devargs string is provided for probing, and updated with a bigger range for a new probing, then we do not want it to fail because part of this range was already probed previously. There can be new ports to create from an existing rte_device. That's why the check for an already probed device is moved as bus responsibility. In the case of vdev, a global check is kept in insert_vdev(), assuming that a vdev will always have only one port. In the case of ifpga and vmbus, already probed devices are checked. In the case of NXP buses, the probing is done only once (no hotplug), though a check is added at bus level for consistency. In the case of PCI, a driver flag is added to allow PMD probing again. Only the PMD knows the ports attached to one rte_device. As another consequence of being able to probe in several steps, the field rte_device.devargs must not be considered as a full representation of the rte_device, but only the latest probing args. Anyway, the field rte_device.devargs is used only for probing.

2018-10-17drivers/bus: move driver assignment to end of probingThomas Monjalon
The PCI mapping requires to know the PCI driver to use, even before the probing is done. That's why the PCI driver is referenced early inside the PCI device structure. See commit 1d20a073fa5e ("bus/pci: reference driver structure before mapping") However the rte_driver does not need to be referenced in rte_device before the device probing is done. By moving back this assignment at the end of the device probing, it becomes possible to make clear the status of a rte_device.

Add support for triggering callbacks when adding, removing, attaching or detaching external memory. Some memory event callback handlers will need additional logic to handle external memory regions. For example, virtio callback has to completely ignore externally allocated memory, because there is no way to find file descriptors backing the memory address in a generic fashion.

When we allocate and use DPDK memory, we need to be able to differentiate between DPDK hugepage segments and segments that were made part of DPDK but are externally allocated. Add such a property to memseg lists. This breaks the ABI, so document the change in release notes. This also breaks a few internal assumptions about memory contiguousness, so adjust malloc code in a few places. All current calls for memseg walk functions were adjusted to ignore external segments where it made sense. Mempools is a special case, because we may be asked to allocate a mempool on a specific socket, and we need to ignore all page sizes on other heaps or other sockets. Previously, this assumption of knowing all page sizes was not a problem, but it will be now, so we have to match socket ID with page size when calculating minimum page size for a mempool.

Currently, DPDK will skip mapping some areas (or even an entire BAR) if MSI-X table happens to be in them but is smaller than page size. Kernels 4.16+ will allow mapping MSI-X BARs [1], and will report this as a capability flag. Capability flags themselves are also only supported since kernel 4.6 [2]. This commit will introduce support for checking VFIO capabilities, and will use it to check if we are allowed to map BARs with MSI-X tables in them, along with backwards compatibility for older kernels, including a workaround for a variable rename in VFIO region info structure [3].
