| | | | | | | | | | | | | | | | | | | | Add clock arbiter skeleton with support of clock sessions, notifications on clock changes, request numbering, and asynchronous handling of clock requests. Provides minimum behaviour to allow unit tests implementation. Actual arbitration and clock settings will be done separately. For now, dummy arbiter keeps last requested target mhz. Actual arbiter may move to a lockless implementation.

| | | | | | | | | | | | | | | | | | | | | | | | | | | We can trigger CILP only if SM debug mode is on. So in fecs interrupt handler, we could have graphics context running for which SM debug mode is disabled. And in that case we skip posting of cilp completion events to UMD.

| | | | | | | | | | | | | | | | | | | | | | | | In gp10b_ce_nonstall_isr(), we trigger a semaphore wakeup. Currently, we clear the interrupt status register after the wakeup is complete. There is potential for an interrupt to come in while the wake-up operation is in progress, and it is possible that: 1) We miss processing the interrupt in that ISR iteration AND 2) We clear the interrupt status register anyways This change clears the status register before triggering wakeup, so the interrupt will properly re-fire.
