10 The syscall is made with the sc instruction, and returns with execution
17 syscall calling sequence\ [1]_ matches the Power Architecture 64-bit ELF ABI
28 There is a maximum of 6 integer parameters to a syscall, passed in r3-r8.
34 clear, the syscall succeeded and r3 is the return value. When cr0.SO is set,
35 the syscall failed and r3 is the error value (that normally corresponds to
88 transaction state, and the syscall can affect the behavior of the transaction.
90 If the processor is in suspended state when a syscall is made, the syscall
91 will be performed as normal, and will return as normal. The syscall will be
