Subject: [PATCH v3 15/37] KVM: s390: protvirt: Implement interrupt injection
Date: Thu, 20 Feb 2020 05:39:58 -0500 [thread overview]
Message-ID: <20200220104020.5343-16-borntraeger@de.ibm.com> (raw)
In-Reply-To: <20200220104020.5343-1-borntraeger@de.ibm.com>
From: Michael Mueller <mimu@linux.ibm.com>
This defines the necessary data structures in the SIE control block to
inject machine checks,external and I/O interrupts. We first define the
the interrupt injection control, which defines the next interrupt to
inject. Then we define the fields that contain the payload for machine
checks,external and I/O interrupts.
This is then used to implement 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.
