1. Add mechanism(s) to trigger syncpoint fence scan when syncpoint increment UMD called. Following methods are added. - METHOD-1: Check fence expire in user context when syncpoint increment UMD API is called. - METHOD-2: Add tasklet based mechanism that schedule tasklet to scan for syncpoint fence expiry. This also improve signaling latency. METHOD-1 is enabled by default, to enable METHOD-2 define MACRO "HOST1X_EMU_SYNC_INC_TASKLET". 2. Add interface "host1x_syncpt_fence_scan()" that can be called from client interrupt handler to initiate syncpoint fence scan.
