[Qemu-ppc] [PATCH v3 08/12] target/ppc: Add new H-CALL shells for in memory table translation |
Date: |
Thu, 2 Mar 2017 16:39:03 +1100 |
From: Suraj Jitindar Singh <address@hidden>
The use of the new in memory tables introduced in ISAv3.00 for translation,
also referred to as process tables, requires the introduction of 3 new
H-CALLs; H_REGISTER_PROCESS_TABLE, H_CLEAN_SLB, and H_INVALIDATE_PID.
Add shells for each of these and register them as the hypercall handlers.
Currently they all log an unimplemented hypercall and return H_FUNCTION.

* Brought in from Suraj's work.
