0204 Description:
0205 The optional "hw_counters" subdirectory can be under either the
0206 parent device or the port subdirectories or both. If present,
0207 there are a list of counters provided by the hardware. They may
0208 match some of the counters in the counters directory, but they
0209 often include many other counters. In addition to the various
0210 counters, there will be a file named "lifespan" that configures
0211 how frequently the core should update the counters when they are
0212 being accessed (counters are not updated if they are not being
0213 accessed). The lifespan is in milliseconds and defaults to 10
0214 unless set to something else by the driver. Users may echo a
0215 value between 0-10000 to the lifespan file to set the length
0216 of time between updates in milliseconds.

0335 Description:
0336 The sysfs iov directory is used to manage and examine the port
0337 P_Key and guid paravirtualization. This directory is added only
0338 for the master -- slaves do not have it.
0339
0340 Under iov/ports, the administrator may examine the gid and P_Key
0341 tables as they are present in the device (and as are seen in the
0342 "network view" presented to the SM).
0343
0344 The "pkeys" and "gids" subdirectories contain one file for each
0345 entry in the port's P_Key or GID table respectively. For
0346 example, ports/1/pkeys/10 contains the value at index 10 in port
0347 1's P_Key table.

0361 <m>/gid_idx/0: (RO) Display the GID mapping m = 1..2
0362
0363 <m>/pkey_idx/<n>: (RW) Writable except for RoCE pkeys.
0364 m = 1..2, n = 0..126
0365
0366 Under the iov/<pci slot number>
0367 directories, the admin may map the index
0368 numbers in the physical tables (as under
0369 iov/ports) to the paravirtualized index
0370 numbers that guests see.
0371
0372 For example, if the administrator, for
0373 port 1 on guest 2 maps physical pkey
0374 index 10 to virtual index 1, then that
0375 guest, whenever it uses its pkey index
0376 1, will actually be using the real pkey
0377 index 10.

0703 cpu_list: (RW) List of cpus for user-process to sdma
0704 engine assignment.
0705
0706 vl: (RO) Displays the virtual lane (vl) the sdma
0707 engine maps to.
0708 =============== ==============================================
0709
0710 This interface gives the user control on the affinity settings
0711 for the device. As an example, to set an sdma engine irq
0712 affinity and thread affinity of a user processes to use the
0713 sdma engine, which is "near" in terms of NUMA configuration, or
0714 physical cpu location, the user will do::
0715
0716 echo "3" > /proc/irq/<N>/smp_affinity_list
0717 echo "4-7" > /sys/devices/.../sdma3/cpu_list
0718 cat /sys/devices/.../sdma3/vl
0719 0
0720 echo "8" > /proc/irq/<M>/smp_affinity_list
0721 echo "9-12" > /sys/devices/.../sdma4/cpu_list
0722 cat /sys/devices/.../sdma4/vl
0723 1
0724
0725 to make sure that when a process runs on cpus 4,5,6, or 7, and
0726 uses vl=0, then sdma engine 3 is selected by the driver, and
0727 also the interrupt of the sdma engine 3 is steered to cpu 3.
0728 Similarly, when a process runs on cpus 9,10,11, or 12 and sets
0729 vl=1, then engine 4 will be selected and the irq of the sdma
0730 engine 4 is steered to cpu 8. This assumes that in the above N
0731 is the irq number of "sdma3", and M is irq number of "sdma4" in
0732 the /proc/interrupts file.
