.SH "DESCRIPTION"
.SS devlink sb show - display available shared buffers and their attributes
.PP
.I "DEV"
- specifies the devlink device to show shared buffers.
If this argument is omitted all shared buffers of all devices are listed.
.PP
.I "SB_INDEX"
- specifies the shared buffer.
If this argument is omitted shared buffer with index 0 is selected.
Behaviour of this argument it the same for every command.
.SS devlink sb pool show - display available pools and their attributes
.PP
.I "DEV"
- specifies the devlink device to show pools.
If this argument is omitted all pools of all devices are listed.
.SS devlink sb pool set - set attributes of pool
.PP
.I "DEV"
- specifies the devlink device to set pool.
.TP
.BI size " POOL_SIZE"
size of the pool in Bytes.
.TP
.BR thtype " { " static " | " dynamic " } "
pool threshold type.
.I static
- Threshold values for the pool will be passed in Bytes.
.I dynamic
- Threshold values ("to_alpha") for the pool will be used to compute alpha parameter according to formula:
.br
.in +16
alpha = 2 ^ (to_alpha - 10)
.in -16
.in +10
The range of the passed value is between 0 to 20. The computed alpha is used to determine the maximum usage of the flow:
.in -10
.br
.in +16
max_usage = alpha / (1 + alpha) * Free_Buffer
.in -16
.SS devlink sb port pool show - display port-pool combinations and threshold for each
.I "DEV/PORT_INDEX"
- specifies the devlink port.
.TP
.BI pool " POOL_INDEX"
pool index.
.SS devlink sb port pool set - set port-pool threshold
.I "DEV/PORT_INDEX"
- specifies the devlink port.
.TP
.BI pool " POOL_INDEX"
pool index.
.TP
.BI th " THRESHOLD"
threshold value. Type of the value is either Bytes or "to_alpha", depends on
.B thtype
set for the pool.
.SS devlink sb tc bind show - display port-TC to pool bindings and threshold for each
.I "DEV/PORT_INDEX"
- specifies the devlink port.
.TP
.BI tc " TC_INDEX"
index of either ingress or egress TC, usually in range 0 to 8 (depends on device).
.TP
.BR type " { " ingress " | " egress " } "
TC type.
.SS devlink sb tc bind set - set port-TC to pool binding with specified threshold
.I "DEV/PORT_INDEX"
- specifies the devlink port.
.TP
.BI tc " TC_INDEX"
index of either ingress or egress TC, usually in range 0 to 8 (depends on device).
.TP
.BR type " { " ingress " | " egress " } "
TC type.
.TP
.BI pool " POOL_INDEX"
index of pool to bind this to.
.TP
.BI th " THRESHOLD"
threshold value. Type of the value is either Bytes or "to_alpha", depends on
.B thtype
set for the pool.
.SS devlink sb occupancy show - display shared buffer occupancy values for device or port
.PP
This command is used to browse shared buffer occupancy values. Values are showed for every port-pool combination as well as for all port-TC combinations (with pool this port-TC is bound to). Format of value is:
.br
.in +16
current_value/max_value
.in -16
Note that before showing values, one has to issue
.b occupancy snapshot
command first.
.PP
.I "DEV"
- specifies the devlink device to show occupancy values for.
.I "DEV/PORT_INDEX"
- specifies the devlink port to show occupancy values for.
.SS devlink sb occupancy snapshot - take occupancy snapshot of shared buffer for device
This command is used to take a snapshot of shared buffer occupancy values. After that, the values can be showed using
.B occupancy show
command.
.PP
.I "DEV"
- specifies the devlink device to take occupancy snapshot on.
.SS devlink sb occupancy clearmax - clear occupancy watermarks of shared buffer for device
This command is used to reset maximal occupancy values reached for whole device. Note that before browsing reset values, one has to issue
.B occupancy snapshot
command.
.PP
.I "DEV"
- specifies the devlink device to clear occupancy watermarks on.
