Add simple IRQ or GPIO base event counter. This device is used to measure
rotation speed of some agricultural devices, so no high frequency on the
counter pin is expected.
The maximal measurement frequency depends on the CPU and system load. On

Hi everyone,
This is V2 for the MQPrio support in mvneta.
This small series adds basic support for mqprio offloading, by having
the rx queueing mirroring the TCs based on VLAN prio fields.
This was tested on Armada 3700, and proves useful to make sure
high-priority traffic has a better chance no
According to Errata #23 "The per-CPU GbE interrupt is limited to Core
0", we can't use the per-cpu interrupt mechanism on the Armada 3700
familly.
This is correctly checked for RSS configuration, but the initial queue
mapping is still done by having the queues spread across all the CPUs in
the sys
Implement a basic MQPrio support, inserting rules in RX that translate
the TC to prio mapping into vlan prio to queues.
The TX logic stays the same as when we don't offload the qdisc.

This new callback is used to get the size of the configuration space
of vDPA devices.

Hi Linus,
The following changes since commit 6ee1d745b7c9fd573fba142a2efdad76a9f1cb04:

Now we have the 'get_config_size()' callback available, so we can
check that 'offset' and 'len' parameters are valid.
When these exceed boundaries, we limit the reading to the available
configuration space in the device, and we return the amount of bytes
read.
We also move vdpa_get_config() imple
Following the discussion with Michael and Jason [1], I reworked a bit
get/set_config() in vdpa.
I changed vdpa_get_config() to check the boundaries and added vdpa_set_config().
When 'offset' or 'len' parameters exceed boundaries, we limit the reading to
the available configuration space in the dev
Let's add a function similar to vpda_get_config() to check the
'offset' and 'len' parameters, call the set_config() device callback,
and return the amount of bytes written.

Maybe we can skip this patch and leave the WARN_ONs in place.
What do you recommend?

Instead of calling the 'set_config' callback directly, we call the
new vdpa_set_config() helper which also checks the parameters.

Hi all,
After merging the nvdimm tree, today's linux-next build (htmldocs)
produced these warnings:

without end-string.

vdpa_get_config() and vdpa_set_config() now are able to read/write
only the bytes available in the device configuration space, also if
the buffer provided is bigger than that.
Let's use this feature to allow the user space application to pass any
buffer. We limit the size of the internal bounce bu
Let's use the new 'get_config_size()' callback available instead of
using the 'virtio_id' to get the size of the device config space.

vdpa_get_config() and vdpa_set_config() now return the amount
of bytes read and written, so let's return them to the user space.
We also modify vhost_vdpa_config_validate() to return 0 (bytes read
or written) instead of an error, when the buffer length is 0.
