vmapi.h@ 38838

Last change on this file since 38838 was 38838, checked in by vboxsync, 13 years ago
VMM,++: Try fix the async reset, suspend and power-off problems in PDM wrt conflicting VMM requests. Split them into priority requests and normal requests. The priority requests can safely be processed when PDM is doing async state change waits, the normal ones cannot. (The problem I bumped into was a unmap-chunk request from PGM being processed during PDMR3Reset, causing a recursive VMMR3EmtRendezvous deadlock.)
