165c89b845 mem: use DMA mask check for legacy memory
If a device reports addressing limitations through a dma mask,
the IOVAs for mapped memory needs to be checked out for ensuring
correct functionality.

Previous patches introduced this DMA check for main memory code
currently being used but other options like legacy memory and the
no hugepages option need to be also considered.

This patch adds the DMA check for those cases.

4374ebc24b malloc: modify error message for DMA mask check
If DMA mask checks shows mapped memory out of the supported range
specified by the DMA mask, nothing can be done but return an error
an report the error. This can imply the app not being executed at
all or precluding dynamic memory allocation once the app is running.
In any case, we can advice the user to force IOVA as PA if currently
IOVA being VA and user being root.

ec20068713 bus/pci: avoid call to DMA mask check
Calling rte_mem_check_dma_mask when memory has not been initialized
yet is wrong. This patch use rte_mem_set_dma_mask instead.

Once memory initialization is done, the dma mask set will be used
for checking memory mapped is within the specified mask.

9d15773606 mem: add function for setting DMA mask
This patch adds the possibility of setting a dma mask to be used
once the memory initialization is done.

This is currently needed when IOVA mode is set by PCI related
code and an x86 IOMMU hardware unit is present. Current code calls
rte_mem_check_dma_mask but it is wrong to do so at that point
because the memory has not been initialized yet.

11b57c6980 eal: fix error string function
errno_autotest testcase were failed since
commit 5d7b673d5fd6 ("mk: build with _GNU_SOURCE defined by default")
RTE>>errno_autotest
rte_strerror: 'Unknown error 11',
strerror: 'Resource temporarily unavailable'
Test Failed

There are two different version of strerror_t() based on
_GNU_SOURCE definition.

/* XSI-compliant */
int strerror_r(int errnum, char *buf, size_t buflen);

/* GNU-specific */
char *strerror_r(int errnum, char *buf, size_t buflen);

Since the GNU-specific version returns char* the exiting "if"
condition around the strerror_r fails.

Switching back to XSI-compliant version to allow

a) Portable strerror_r() usage as musl c library uses
non GNU speficic version
https://git.musl-libc.org/cgit/musl/tree/src/string/strerror_r.c

b) Based on strerror_r(3) man page, it is possible that GNU-specific
version need not use char *buf to fill error message instead it
can use the immutable static string from the library and return it.

note from strerror_r(3) man page:

The GNU-specific strerror_r() returns a pointer to a string containing
the error message.  This may be either a pointer to a string that the
function stores in buf, or a pointer to some (immutable)
static string (in which case buf is unused).

8d07c82b23 mk: disable gcc AVX512F support
This is a workaround to prevent a crash, which might be caused by
optimization of newer gcc (7.3.0) on Intel Skylake.

This disables AVX512F support of gcc by adding -mno-avx512f if it is
disabled in DPDK (CONFIG_RTE_ENABLE_AVX512=n).

This does not apply to the meson build as that doesn't have such an option
but always enable AVX512F whenever supported.

c12ade20c2 examples/vm_power: respect maximum CPUs
The vm_power_manager app was not respecting the POWER_MGR_MAX_CPUS
during initialisation, so if there were more CPUs than this value (64),
it would lead to buffer overruns of there were more then 64 cores in
the system.

Added in a check during init and un-init to only initialise up to
lcore_id 63.

This raises the question as to why not simply increase the value of
POWER_MGR_MAX_CPUS. Well, it's not that simple, as many of the APIs take
a uint64_t as a parameter for the core mask, and this will not work for
cores greater than 63. So some work needs to be done in the future to
remove this limitation. For now we'll fix the memory corruption.

Also, the patch that this fixes says "allow greater than 64 cores" but
that's not across the entire application, it's only for the out-of-band
monitoring. I'll add a notice for an API change in the next release to
clean this up, i.e. depricate any API calls that use masks.

349ac52bbc eal/linux: handle UIO read failure in interrupt handler
If a device is unplugged while an interrupt is pending, the
read call to the uio device to remove it from the poll wait list
can fail resulting in it being continually polled forever. This
change checks for the read failing and if so, unregisters the device
as an interrupt source and causes the wait list to be rebuilt.

6c99085d97 net/vmxnet3: fix hot-unplug
The vmxnet3 driver can't call back into dev_close(), and possibly
dev_stop(), in dev_uninit().  When dev_uninit() is called, anything
that those routines would want to clean up has already been released.
Further, for complete cleanup, it is necessary to release any of the
queue resources during dev_close().
This allows a vmxnet3 device to be hot-unplugged without leaking
queues.
Also set RTE_ETH_DEV_CLOSE_REMOVE on close so that the port resources
can be deallocated.
Return EBUSY if remove is called before stop.

6bcb7c95fe vfio: share default container in multi-process
So far each process in MP used to have a separate container
and relied on the primary process to register all memsegs.

Mapping external memory via rte_vfio_container_dma_map()
in secondary processes was broken, because the default
(process-local) container had no groups bound. There was
even no way to bind any groups to it, because the container
fd was deeply encapsulated within EAL.

This patch introduces a new SOCKET_REQ_DEFAULT_CONTAINER
message type for MP synchronization, makes all processes
within a MP party use a single default container, and hence
fixes rte_vfio_container_dma_map() for secondary processes.

From what I checked this behavior was always the same, but
started to be invalid/insufficient once mapping external
memory was allowed.

While here, fix up the comment on rte_vfio_get_container_fd().
This function always opens a new container, never reuses
an old one.

630deed612 bus/pci: compare kernel driver instead of interrupt handler
Invoking the right pci read/write functions is based on interrupt
handler type. However, this is not configured for secondary processes
precluding to use those functions.

This patch fixes the issue using the driver name the device is bound
to instead.

49bb1f7a0a net/virtio: fix PCI config error handling
In virtio_read_caps and vtpci_msix_detect, rte_pci_read_config returns
the number of bytes read from PCI config or < 0 on error.
If less than the expected number of bytes are read then log the
failure and return rather than carrying on with garbage.

e8d435f1f3 bus/pci: harmonize return value of config read
On Linux, rte_pci_read_config on success returns the number of read
bytes, but on BSD it returns 0.
Document the return values, and have BSD behave as Linux does.

At least one case (bnx2x PMD) treats 0 as an error, so the change
makes sense also for that.

075b182b54 eal: force IOVA to a particular mode
This patch uses EAL option "--iova-mode" to force the IOVA mode to a
particular value. There exists virtual devices that are not directly
attached to the PCI bus, and therefore the auto detection of the IOVA
mode based on probing the PCI bus and IOMMU configuration may not
report the required addressing mode. Using the EAL option permits the
mode to be explicitly configured in this scenario.

783667c9f9 eal: add --iova-mode option
In the case of user don't want to use bus iova scheme and want
to override.

For that, adding EAL option --iova-mode=<string> where valid input
string is 'pa' or 'va'.

998c89f148 vfio: fix sPAPR IOMMU mapping
Commit 73a639085938 ("vfio: allow to map other memory regions")
introduced a bug in sPAPR IOMMU mapping. The commit removed necessary
ioctl with VFIO_IOMMU_SPAPR_REGISTER_MEMORY. Also, vfio_spapr_map_walk
should call vfio_spapr_dma_do_map instead of vfio_spapr_dma_mem_map.
