charset="utf-8" Specify which level (core/cluster/socket) caches found at in the CPU topology. Updating cache topology to device tree (spec v0.4). Example: For example, 2 sockets (packages), and 2 clusters, 4 cores and 2 threads created, in aggregate 2*2*4*2 logical cores. In the smp-cache object, cores will have L1d and L1i. However, extending this is not difficult. The clusters will share a unified L2 level cache, and finally sockets will share L3. In this patch, threads will share L1 caches by default, but this can be adjusted if case required. Only three levels of caches are supported. The patch does not allow partial declaration of caches. In other words, the topology level of every cache must be specified if that of any level is. ./qemu-system-aarch64 \ -machine virt,\ smp-cache.0.cache=3Dl1i,smp-cache.0.topology=3Dcore,\ smp-cache.1.cache=3Dl1d,smp-cache.1.topology=3Dcore,\ smp-cache.2.cache=3Dl2,smp-cache.2.topology=3Dcluster,\ smp-cache.3.cache=3Dl3,smp-cache.3.topology=3Dsocket\ -cpu max \ -m 2048 \ -smp sockets=3D2,clusters=3D2,cores=3D4,threads=3D1 \ -kernel ./Image.gz \ -append "console=3DttyAMA0 root=3D/dev/ram rdinit=3D/init acpi=3Dforce"= \ -initrd rootfs.cpio.gz \ -bios ./edk2-aarch64-code.fd \ -nographic For instance, following device tree will be generated for a scenario where we have 2 sockets, 2 clusters, 2 cores and 2 threads, in total 16 PEs. L1i and L1d are private to each thread, and L2 and L3 are shared at socket level as an example. Limitation: SMT cores cannot share L1 cache for now. This problem does not exist in PPTT tables.
