Subject: [PATCH v2 16/42] KVM: s390: protvirt: Implement interruption injection
Date: Fri, 14 Feb 2020 17:26:32 -0500 [thread overview]
Message-ID: <20200214222658.12946-17-borntraeger@de.ibm.com> (raw)
In-Reply-To: <20200214222658.12946-1-borntraeger@de.ibm.com>
From: Michael Mueller <mimu@linux.ibm.com>
The patch implements interruption injection for the following
list of interruption types:
- I/O (uses inject io interruption)
__deliver_io
- External (uses inject external interruption)
__deliver_cpu_timer
__deliver_ckc
__deliver_emergency_signal
__deliver_external_call
- cpu restart (uses inject restart interruption)
__deliver_restart
- machine checks (uses mcic, failing address and external damage)
__write_machine_check
Please note that posted interrupts (GISA) are not used for protected
guests as of today.
The service interrupt is handled in a followup patch.
