Subject: [PATCH 3/8] target/hexagon: kick vCPU when re-asserting interrupts
Date: Thu, 3 Sep 2026 11:56:17 -0700 [thread overview]
Message-ID: <20260903185622.3234171-4-brian.cain@oss.qualcomm.com> (raw)
In-Reply-To: <20260903185622.3234171-1-brian.cain@oss.qualcomm.com>
hex_interrupt_update() used cpu_resume() to make a halted vCPU notice a
newly pending interrupt. cpu_resume() is meant for a vCPU stopped by the
vm-state machinery: besides kicking the thread it clears cpu->stop and
cpu->stopped, and resets exception_index to -1. Clearing the stop flags
can undo a pause requested via the monitor or by migration, and resetting
exception_index discards an exception the vCPU had already latched.
Only the kick is wanted here, so call qemu_cpu_kick() directly.
