Advanced Configuration and Power Interface Specification Status Code 0x90-0x9F 0xA0-0xFFFFFFFF Description Insertion failure – Resources Unavailable as described by the following bit encodings: Bit [3] Bus or Segment Numbers Bit [2] Interrupts Bit [1] I/O Bit [0] Memory Reserved It is possible for the platform to issue multiple notifications to OSPM and for OSPM to process the notifications asynchronously. As such, OSPM may invoke _OST for notifications independent of the order the notification are conveyed by the platform or by software to OSPM. The figure below provides and example event flow of device ejection on a platform employing the _OST object. 338 April, 2015 Version 6.0
Device Configuration User interacts with OSPM to request device ejection User Presses Hardware Eject Button Platform generates GPE/SCI OSPM evaluates _OST(0x103,84,””) Platform blinks Ejection Progress Light OSPM evaluation of GPE Status method generates Notify(device,3(eject)) OSPM Processes Ejection Request Application connections to device closed . OS Ejection Successful ? No OSPM evaluates _OST(0x103,81,””) or _OST(0x03,81,””) Platform turns off Ejection Progress Light and turns on Ejection Failure Light Done Yes Evaluate _EJx x = 0 in _EJx? No OSPM places system into sleep state Platform ejection occurs Platform wakeup occurs Yes Platform turns off Ejection Progress Light Done Figure 6-38 Device Ejection Flow Example Using _OST Version 6.0 339
