+Date: May, 2016
+KernelVersion: 4.6
+Contact: linux-rdma@vger.kernel.org
+Description:
+ The optional "hw_counters" subdirectory can be under either the
+ parent device or the port subdirectories or both. If present,
+ there are a list of counters provided by the hardware. They may
+ match some of the counters in the counters directory, but they
+ often include many other counters. In addition to the various
+ counters, there will be a file named "lifespan" that configures
+ how frequently the core should update the counters when they are
+ being accessed (counters are not updated if they are not being
+ accessed). The lifespan is in milliseconds and defaults to 10
+ unless set to something else by the driver. Users may echo a
+ value between 0-10000 to the lifespan file to set the length
+ of time between updates in milliseconds.

+Description:
+ The sysfs iov directory is used to manage and examine the port
+ P_Key and guid paravirtualization. This directory is added only
+ for the master -- slaves do not have it.
+
+ Under iov/ports, the administrator may examine the gid and P_Key
+ tables as they are present in the device (and as are seen in the
+ "network view" presented to the SM).
+
+ The "pkeys" and "gids" subdirectories contain one file for each
+ entry in the port's P_Key or GID table respectively. For
+ example, ports/1/pkeys/10 contains the value at index 10 in port
+ 1's P_Key table.
+
+ gids/<n>: (RO) The physical port gids n = 0..127
+
+ admin_guids/<n>: (RW) Allows examining or changing the
+ administrative state of a given GUID
+ n = 0..127
+
+ pkeys/<n>: (RO) Displays the contents of the physical
+ key table n = 0..126
+
+ mcgs/: (RO) Muticast group table
+
+ <m>/gid_idx/0: (RO) Display the GID mapping m = 1..2
+
+ <m>/pkey_idx/<n>: (RW) Writable except for RoCE pkeys.
+ m = 1..2, n = 0..126
+
+ Under the iov/<pci slot number>
+ directories, the admin may map the index
+ numbers in the physical tables (as under
+ iov/ports) to the paravirtualized index
+ numbers that guests see.
+
+ For example, if the administrator, for
+ port 1 on guest 2 maps physical pkey
+ index 10 to virtual index 1, then that
+ guest, whenever it uses its pkey index
+ 1, will actually be using the real pkey
+ index 10.

+
+ smi_enabled: (RO) Indicates whether smi is currently enabled
+ for the indicated VF/port
+
+ enable_smi_admin:(RW) Used by the admin to request that smi
+ capability be enabled or disabled for the

+Description:
+ sdma<N>/ contains one directory per sdma engine (0 - 15)
+
+ cpu_list: (RW) List of cpus for user-process to sdma
+ engine assignment.
+
+ vl: (RO) Displays the virtual lane (vl) the sdma
+ engine maps to.
+
+ This interface gives the user control on the affinity settings
+ for the device. As an example, to set an sdma engine irq
+ affinity and thread affinity of a user processes to use the
+ sdma engine, which is "near" in terms of NUMA configuration, or
+ physical cpu location, the user will do:
+
+ echo "3" > /proc/irq/<N>/smp_affinity_list
+ echo "4-7" > /sys/devices/.../sdma3/cpu_list
+ cat /sys/devices/.../sdma3/vl
+ 0
+ echo "8" > /proc/irq/<M>/smp_affinity_list
+ echo "9-12" > /sys/devices/.../sdma4/cpu_list
+ cat /sys/devices/.../sdma4/vl
+ 1
+
+ to make sure that when a process runs on cpus 4,5,6, or 7, and
+ uses vl=0, then sdma engine 3 is selected by the driver, and
+ also the interrupt of the sdma engine 3 is steered to cpu 3.
+ Similarly, when a process runs on cpus 9,10,11, or 12 and sets
+ vl=1, then engine 4 will be selected and the irq of the sdma
+ engine 4 is steered to cpu 8. This assumes that in the above N
+ is the irq number of "sdma3", and M is irq number of "sdma4" in
+ the /proc/interrupts file.
