Subject: [PATCH v4 5/6] target/ppc: Add ISA v3.1 LEV indication in SRR1 for system call interrupts
Date: Tue, 30 May 2023 23:25:42 +1000 [thread overview]
Message-ID: <20230530132543.385138-6-npiggin@gmail.com> (raw)
In-Reply-To: <20230530132543.385138-1-npiggin@gmail.com>
System call interrupts in ISA v3.1 CPUs add a LEV indication in SRR1
that corresponds with the LEV field of the instruction that caused the
interrupt.
