====================
aux-sysfs-irqs

Shay Says:
==========
Introduce auxiliary bus IRQs sysfs

Today, PCI PFs and VFs, which are anchored on the PCI bus, display their
IRQ information in the &lt;pci_device&gt;/msi_irqs/&lt;irq_num&gt; sysfs files.  PCI
subfunctions (SFs) are similar to PFs and VFs and these SFs are anchored
on the auxiliary bus. However, these PCI SFs lack such IRQ information
on the auxiliary bus, leaving users without visibility into which IRQs
are used by the SFs. This absence makes it impossible to debug
situations and to understand the source of interrupts/SFs for
performance tuning and debug.

Additionally, the SFs are multifunctional devices supporting RDMA,
network devices, clocks, and more, similar to their peer PCI PFs and
VFs. Therefore, it is desirable to have SFs' IRQ information available
at the bus/device level.

To overcome the above limitations, this short series extends the
auxiliary bus to display IRQ information in sysfs, similar to that of
PFs and VFs.

It adds an 'irqs' directory under the auxiliary device and includes an
&lt;irq_num&gt; sysfs file within it.

For example:
$ ls /sys/bus/auxiliary/devices/mlx5_core.sf.1/irqs/
50  51  52  53  54  55  56  57  58

Patch summary:
patch-1 adds auxiliary bus to support irqs used by auxiliary device
patch-2 mlx5 driver using exposing irqs for PCI SF devices via auxiliary
        bus

Add mana_get_primary_netdev_rcu helper to get a primary
netdevice for a given port. When mana is used with
netvsc, the VF netdev is controlled by an upper netvsc
device. In a baremetal case, the VF netdev is the
primary device.

Use the mana_get_primary_netdev_rcu() helper in the mana_ib

<content type='text'>
When map a device between servers with MLX and BCM RoCE nics, RTRS
server complain about unknown imm type, and can't map the device,

After more debug, it seems bnxt_re wrongly handle the
imm_data, this patch fixed the compat issue with MLX for us.

In off list discussion, Selvin confirmed HW is working in little endian format
and all data needs to be converted to LE while providing.

This patch fix the endianness for imm_data

When map a device between servers with MLX and BCM RoCE nics, RTRS
server complain about unknown imm type, and can't map the device,

After more debug, it seems bnxt_re wrongly handle the
imm_data, this patch fixed the compat issue with MLX for us.

In off list discussion, Selvin confirmed HW is working in little endian format
and all data needs to be converted to LE while providing.

This patch fix the endianness for imm_data

If a netdev has already been assigned, ib_device_set_netdev needs to
release the reference on the older netdev but it is mistakenly being
called for the new netdev. Fix it and in the process use netdev_put
to be symmetrical with the netdev_hold.

<title>RDMA/hns: Fix mbx timing out before CMD execution is completed</title>

When a large number of tasks are issued, the speed of HW processing
mbx will slow down. The standard for judging mbx timeout in the current
firmware is 30ms, and the current timeout standard for the driver is also
30ms.

Considering that firmware scheduling in multi-function scenarios takes a
certain amount of time, this will cause the driver to time out too early
and report a failure before mbx execution times out.

This patch introduces a new mechanism that can set different timeouts for
different cmds and extends the timeout of mbx to 35ms.

VFs and its PF will share the memory of the extend DB. Currently,
the number of extend DB allocated by driver is only enough for PF.
This leads to a probability of DB loss and some other problems in
scenarios where both PF and VFs use a large number of QPs.
