Subject: [PATCH v9 02/21] target/s390x: Rework s390 cpacf implementations
Date: Wed, 1 Jul 2026 18:46:25 +0200 [thread overview]
Message-ID: <20260701164650.95760-3-freude@linux.ibm.com> (raw)
In-Reply-To: <20260701164650.95760-1-freude@linux.ibm.com>
Fix missing parts for MSA 9 kdsa and rework the cpacf handling code
so that further extensions can be made in a clean and structured way.
Introduce a new header file to hold defines, structs and function
prototypes around s390 cpacf. Use the cpcaf function defines in the
existing code.
