Name:Map the memory b/w percentage value to delay values* that can be written to QOS_MSRs.* There are currently no SKUs which support non linear delay values.
Proto:unsigned int delay_bw_map(unsigned long bw, struct rdt_resource *r)
Type:unsigned int
Parameter:
| Type | Parameter | Name |
|---|---|---|
| unsigned long | bw | |
| struct rdt_resource * | r |
| 378 | If delay_linear Then Return MAX_MBA_BW - bw |
| 381 | pr_warn_once("Non Linear delay-bw map not supported but queried\n") |
| 382 | Return default_ctrl |

| update_mba_bw | Feedback loop for MBA software controller (mba_sc)* mba_sc is a feedback loop where we periodically read MBM counters and* adjust the bandwidth percentage values via the IA32_MBA_THRTL_MSRs so* that:* current bandwdith(cur_bw) < user specified |
