* Support HB running in SMFDean Sanner2018-09-241-1/+3
| | | | | | | | | | | | | | | | | | | | | | Support SMF for P9N/P9C. Lots of minor tweaks to make this work, but the biggest is to run userspace in problem state This is needed because for SMF Hostboot will need to run in S=1, HV=0,PR=1 (and kernel in S=1, HV=1, PR=0) This commit makes P9 HB userpsace run in HV=0 PR=1 and kernel in HV=1, PR=0.

* Support task_wait / task_wait_tid syscalls:Patrick Williams2011-10-241-0/+53
| | | | | | | | | | | | | | | | | | | | | | | | | - Add task_end2 syscall to allow pthread_exit-like retval. - Add/maintain task states. - Create task parent/child tracking tree. - Add task_detach function. - Implement wait syscalls. Make task_exec caller the parent of spawned task: Previously the task_exec call caused a message to the VFS task, which called task_create and returned the tid in response to the message. This causes the parent of the spawned task to appear to be the VFS task. Modify task_exec / VFS handling to instead return the entry point address on the message and have task_exec call task_create directly itself.
