| H A D | megaraid_sas.h | 308ec459 Thu Jan 28 09:34:30 CST 2016 Sumit Saxena <sumit.saxena@avagotech.com> megaraid_sas: Dual queue depth support
1. For iMR controllers, firmware will report two queue depths:
- Controller-wide queue depth
- LDIO queue depth (240)
Controller-wide queue depth will be greater among the two. Using this
new feature, iMR can provide larger Queue depth(QD) for JBOD and limited
QD for Virtual Disk(VD).
2. megaraid_sas driver will throttle read/write LDIOs based on "LDIO
Queue Depth".
3. Dual queue depth can be enabled/disabled via module parameter. It is
enabled by default if the firmware supports it. Only specific firmware
builds will enable the feature.
4. Added sysfs parameter "ldio_outstanding" which permits querying the
number of outstanding LDIO requests at runtime.
