Subject: [RFC PATCH 00/15] acrn: add the ACRN driver module
Date: Fri, 16 Aug 2019 10:25:41 +0800 [thread overview]
Message-ID: <1565922356-4488-1-git-send-email-yakui.zhao@intel.com> (raw)
ACRN is a flexible, lightweight reference hypervisor, built with real-time
and safety-criticality in mind, optimized to streamline embedded development
through an open source platform. It is built for embedded IOT with small
footprint and real-time features. More details can be found
in https://projectacrn.org/
This is the patch set that add the ACRN driver module on ACRN guest, which
acts as the router to communciate with ACRN hypervisor.
The user-space applications can use the provided ACRN ioctls to
interact with ACRN hypervisor through different hypercalls. After the ACRN
module is loaded, the device file of /dev/acrn_hsm can be accessed in
user-space. It includes the management of virtualized CPU/memory/
device/interrupt/MMIO emulation for other ACRN guest.
The first three patches are the changes under x86/acrn, which adds the
required APIs for the driver and reports the X2APIC caps.
The remaining patches add the ACRN driver module, which accepts the ioctl
from user-space and then communicate with the low-level ACRN hypervisor
by using hypercall.
Zhao Yakui (15):
x86/acrn: Report X2APIC for ACRN guest
x86/acrn: Add two APIs to add/remove driver-specific upcall ISR handler
x86/acrn: Add hypercall for ACRN guest
drivers/acrn: add the basic framework of acrn char device driver
drivers/acrn: add driver-specific hypercall for ACRN_HSM
drivers/acrn: add the support of querying ACRN api version
drivers/acrn: add acrn vm/vcpu management for ACRN_HSM char device
drivers/acrn: add VM memory management for ACRN char device
drivers/acrn: add passthrough device support
drivers/acrn: add interrupt injection support

drivers/acrn: add driver-specific IRQ handle to dispatch IO_REQ request
drivers/acrn: add service to obtain Power data transition
drivers/acrn: add the support of irqfd and eventfd
drivers/acrn: add the support of offline SOS cpu
