For example, if RPTUN_IVSHMEM_CPUNAME = "0:cpu1:m;1:cpu2:s" and pass two ivshmem devices to the qemu, we will get two rptun ivshmem drivers with ivshmem device match id: [0, 1], remote cpu names: ["cpu1", "cpu2"] and roles: ["master", "slave"'] config RPTUN_IVSHMEM_BUFFSIZE int "rptun ivshmem rpmsg buffer size" default 2048 ---help--- The rpmsg buffer size in resource table, the RX and TX buffer size are same for now. config RPTUN_IVSHMEM_BUFFNUM int "rptun ivshmem rpmsg buffer number" default 8 ---help--- The rpmsg buffer number in resource table, the RX and TX buffer number are same for now. endif config RPTUN_PRIORITY int "rptun thread priority" default 224 config RPTUN_STACKSIZE int "rptun stack size" default 4096 config RPTUN_LOADER bool "rptun loader support" default n config RPTUN_PM bool "rptun power management" depends on PM default n ---help--- If TX/RX buffer is supplied and powered by each CPU. And when one CPU in DEEP sleep, then it's buffer will goto RAM-retention mode, can't access from another CPU. So, we provide this method to resolve this. endif # RPTUN
