Wind River Linux virtualization supports both virtualization styles, either in separated virtual nodes as illustrated in the figure, or inside a single. It allows you to create and run virtual machines on a Linux host system using hardware acceleration, providing high performance and low overhead. */ #include "qemu/osdep.h" #include "qapi/error.h" #include "qemu/log.h" #include "chardev/char.h" #include "chardev/char-fe.h" #include "hw/irq.h" #include "hw/char/sifive_uart.h" /* * Not yet implemented: * * Transmit FIFO using "qemu/fifo8.h" */ /* Returns the state of the IP (interrupt pending) register */ static uint64_t uart_ip ( SiFiveUARTState * s ) Kernel-based Virtual Machine (KVM) is an open-source virtualization solution built into the Linux kernel. * * You should have received a copy of the GNU General Public License along with * this program.
