5e046832f1 ethdev: rename memzones allocated for DMA
The helper rte_eth_dma_zone_reserve() is called by PMDs
when probing a new port.
It creates a new memzone with an unique name.
The name of this memzone was using the name of the driver
doing the probe.

In order to avoid assigning the driver before the end of the probing,
the driver name is removed from these memzone names.
The ethdev name (data->name) is not used because it may be too long
and may be not set at this stage of probing.

Syntax of old name: <driver>_<ring>_<port>_<queue>
Syntax of new name: eth_p<port>_q<queue>_<ring>

ac9e4a1737 eal: support attach/detach shared device from secondary
This patch cover the multi-process hotplug case when a device
attach/detach request be issued from a secondary process

device attach on secondary:
a) secondary send sync request to the primary.
b) primary receive the request and attach the new device if
   failed goto i).
c) primary forward attach sync request to all secondary.
d) secondary receive the request and attach the device and send a reply.
e) primary check the reply if all success goes to j).
f) primary send attach rollback sync request to all secondary.
g) secondary receive the request and detach the device and send a reply.
h) primary receive the reply and detach device as rollback action.
i) send attach fail to secondary as a reply of step a), goto k).
j) send attach success to secondary as a reply of step a).
k) secondary receive reply and return.

device detach on secondary:
a) secondary send sync request to the primary.
b) primary send detach sync request to all secondary.
c) secondary detach the device and send a reply.
d) primary check the reply if all success goes to g).
e) primary send detach rollback sync request to all secondary.
f) secondary receive the request and attach back device. goto h).
g) primary detach the device if success goto i), else goto e).
h) primary send detach fail to secondary as a reply of step a), goto j).
i) primary send detach success to secondary as a reply of step a).
j) secondary receive reply and return.

244d513071 eal: enable hotplug on multi-process
We are going to introduce the solution to handle hotplug in
multi-process, it includes the below scenario:

1. Attach a device from the primary
2. Detach a device from the primary
3. Attach a device from a secondary
4. Detach a device from a secondary

In the primary-secondary process model, we assume devices are shared
by default. that means attaches or detaches a device on any process
will broadcast to all other processes through mp channel then device
information will be synchronized on all processes.

Any failure during attaching/detaching process will cause inconsistent
status between processes, so proper rollback action should be considered.

This patch covers the implementation of case 1,2.
Case 3,4 will be implemented on a separate patch.

IPC scenario for Case 1, 2:

attach a device
a) primary attach the new device if failed goto h).
b) primary send attach sync request to all secondary.
c) secondary receive request and attach the device and send a reply.
d) primary check the reply if all success goes to i).
e) primary send attach rollback sync request to all secondary.
f) secondary receive the request and detach the device and send a reply.
g) primary receive the reply and detach device as rollback action.
h) attach fail
i) attach success

detach a device
a) primary send detach sync request to all secondary
b) secondary detach the device and send reply
c) primary check the reply if all success goes to f).
d) primary send detach rollback sync request to all secondary.
e) secondary receive the request and attach back device. goto g)
f) primary detach the device if success goto g), else goto d)
g) detach fail.
h) detach success.

0fc54536b1 eal: add failure handling for hot-unplug
The mechanism can initially register the sigbus handler after the device
event monitor is enabled. When a sigbus event is captured, it will check
the failure address and accordingly handle the memory failure of the
corresponding device by invoke the hot-unplug handler. It could prevent
the application from crashing when a device is hot-unplugged.

By this patch, users could call below new added APIs to enable/disable
the device hotplug handle mechanism. Note that it just implement the
hot-unplug handler in these functions, the other handler of hotplug, such
as handler for hotplug binding, could be add in the future if need:
  - rte_dev_hotplug_handle_enable
  - rte_dev_hotplug_handle_disable

This patch adds them and reorders others to match rte_flow.h. It doesn't

rte_flow_conv() would have to be backported as well: this function is
the only sane approach to handle VXLAN and NVGRE encap definitions.

(attributes, pattern and list of actions, all at once), however
applications sometimes need more flexibility, for instance the ability
to duplicate only one of the underlying objects (a single pattern item

Instead of adding dedicated functions to handle each possible use case,
this patch introduces rte_flow_conv(), which supports any number of

This patch re-implements rte_flow_copy() as a wrapper to
rte_flow_conv().

911462eb4a eal: simplify parameters of hotplug functions
All information about a device to probe can be grouped
in a common string, which is what we usually call devargs.
An application should not have to parse this string before
calling the EAL probe function.
And the syntax could evolve to be more complex and support
matching multiple devices in one string.
That's why the bus name and device name should be removed from
rte_eal_hotplug_add().
Instead of changing this function, a simpler one is added
and used in the old one, which may be deprecated later.

When removing a device, we already know its rte_device handle
which can be directly passed as parameter of rte_eal_hotplug_remove().
If the rte_device is not known, it can be retrieved with the devargs,
by iterating in the device list (future RTE_DEV_FOREACH()).
Similarly to the probing case, a new function is added
and used in the old one, which may be deprecated later.
The new function is used in failsafe, because the replacement is easy.

It will make possible to remove a rte_device,
using the function pointer from its bus.

The function rte_bus_find_by_device() becomes useless,
and may be removed later.

2effa126fb devargs: simplify parameters of removal function
The function rte_devargs_remove(), which is intended to be internal,
can take a devargs structure as argument.
The matching is still using string comparison of bus name and
device name.
It is simpler and may allow a different devargs matching in future.

e7ec4d2fc8 devargs: remove deprecated functions
rte_eal_parse_devargs_str() does not support parsing the bus name
at the start of devargs. So it was renamed and deprecated.

rte_eal_devargs_add(), rte_eal_devargs_type_count() and
rte_eal_devargs_dump() were declared deprecated and had their
implementation body renamed.

All these functions were deprecated in release 18.05.

3f7a40c670 devargs: rename enum items with singular form
The enum names are *_params (plural form).
And the items are also using the plural form: *_PARAMS_*.
It looks more natural to use the singular form *_PARAM_* for items.

8e1fdcaa3d mem: fix --huge-unlink option
The final_va field is set during remap_segment() but this information is
not propagated to temporal copy of huge page memory configuration so the
unlink_hugepage_files() function wrongly assume that there is nothing to
unlink. Fix this issue by checking orig_va instead of final_va.

f32c7c9de9 malloc: enable event callbacks for external memory
When adding or removing external memory from the memory map, there
may be actions that need to be taken on account of this memory (e.g.
DMA mapping). 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. All other callbacks have also been adjusted to
handle RTE_BAD_IOVA as IOVA address, as this is one of the expected
use cases for external memory support.

ff3619d624 malloc: allow attaching to external memory chunks
In order to use external memory in multiple processes, we need to
attach to primary process's memseg lists, so add a new API to do
that. It is the responsibility of the user to ensure that memory
is accessible and that it has been previously added to the malloc
heap by another process.

Add an API to remove memory from specified heaps. This will first
check if all elements within the region are free, and that the
region is the original region that was added to the heap (by
comparing its length to length of memory addressed by the
underlying memseg list).
