Jordan Niethe	737ebd92f5	tests: Add tests for the PVR The PVR is a privileged read-only SPR. Test reading and writing in both supervisor and problem state. In supervisor state reading returns microwatt's assigned PVR number and writing is a noop. In problem state both reading and writing cause privileged instruction interrupts.

Shawn Anastasio	8b161c6dc6	Add a new misc test suite with addpcis tests The two tests obtain NIA with bl+mflr+addi and then compare it against addpcis with the minimum and maximum immediate operand values. They were also tested on a real POWER9 system (in userspace) for good measure. Signed-off-by: Shawn Anastasio <shawn@anastas.io>	5 years ago

tests: Add tests for the PVR

The PVR is a privileged read-only SPR. Test reading and writing in both
supervisor and problem state. In supervisor state reading returns
microwatt's assigned PVR number and writing is a noop. In problem state
both reading and writing cause privileged instruction interrupts.

Add a new misc test suite with addpcis tests

The two tests obtain NIA with bl+mflr+addi and then compare it
against addpcis with the minimum and maximum immediate operand values.

They were also tested on a real POWER9 system (in userspace) for good
measure.
