| Date: January 2024 | ||
| KernelVersion: 6.7 | ||
| Contact: qat-linux@intel.com | ||
| Description: | ||
| (WO) This attribute is used to perform an operation on an SLA. | ||
| The supported operations are: add, update, rm, rm_all, and get. | ||
|
|
||
| Input values must be filled through the associated attribute in | ||
| this group before a write to this file. | ||
| If the operation completes successfully, the associated | ||
| attributes will be updated. | ||
| The associated attributes are: cir, pir, srv, rp, and id. | ||
|
|
||
| Supported operations: | ||
|
|
||
| * add: Creates a new SLA with the provided inputs from user. | ||
| * Inputs: cir, pir, srv, and rp | ||
| * Output: id | ||
|
|
||
| * get: Returns the configuration of the specified SLA in id attribute | ||
| * Inputs: id | ||
| * Outputs: cir, pir, srv, and rp | ||
|
|
||
| * update: Updates the SLA with new values set in the following attributes | ||
| * Inputs: id, cir, and pir | ||
|
|
||
| * rm: Removes the specified SLA in the id attribute. | ||
| * Inputs: id | ||
|
|
||
| * rm_all: Removes all the configured SLAs. | ||
| * Inputs: None | ||
|

| Description: | ||
| (RW) When read, reports the current assigned ring pairs for the | ||
| queried SLA. | ||
| When wrote to, configures the ring pairs associated to a new SLA. | ||
|
|
||
| The value is a 64-bit bit mask and is written/displayed in hex. | ||
| Each bit of this mask represents a single ring pair i.e., | ||
| bit 1 == ring pair id 0; bit 3 == ring pair id 2. | ||
|
|
||
| Selected ring pairs must to be assigned to a single service, | ||
| i.e. the one provided with the srv attribute. The service | ||
| assigned to a certain ring pair can be checked by querying | ||
| the attribute qat/rp2srv. | ||
|
|
||
| The maximum number of ring pairs is 4 per SLA. | ||
|
|
||
| Applicability in sla_op: | ||
|

| ## Read | ||
| # echo 4 > /sys/bus/pci/devices/<BDF>/qat_rl/id | ||

| Description: | ||
| (RW) If written to, the value is used to retrieve a particular | ||
| SLA and operate on it. | ||
| This is valid only for the following operations: update, rm, | ||
| and get. | ||
| A read of this attribute is only guaranteed to have correct data | ||

| permille scale, i.e. 1000 refers to the maximum device | ||
| throughput for a selected service. | ||
|
|
||
| After sending a "get" to sla_op, this will be populated with the | ||

|
|
||
| After sending a "get" to sla_op, this will be populated with the | ||
