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.

|
The requested enablement will occur at the next reset of the VF

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.
