Example: Here, 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 (threads will share these caches by default. 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. Currently only three levels of caches are supported. Also, PPTT table revision has been increased to 3 even in scenarios where there are no caches. The patch does not allow partial declaration of caches. In another word, all caches must be defined or caches must be skipped. ./qemu-system-aarch64 \ -machine virt,smp-cache.0.cache=l1i,smp-cache.0.topology=core,smp-cache.1.cache=l1d,smp-cache.1.topology=core,smp-cache.2.cache=l2,smp-cache.2.topology=cluster,smp-cache.3.cache=l3,smp-cache.3.topology=socket \ -cpu max \ -m 2048 \ -smp sockets=2,clusters=2,cores=4,threads=2 \ -kernel ./Image.gz \ -append "console=ttyAMA0 root=/dev/ram rdinit=/init acpi=force" \ -initrd rootfs.cpio.gz \ -bios ./edk2-aarch64-code.fd \ -nographic Signed-off-by: Alireza Sanaee Co-developed-by: Jonathan Cameron Signed-off-by: Jonathan Cameron --- hw/acpi/aml-build.c | 310 +++++++++++++++++++++++++++++++++++- hw/arm/virt-acpi-build.c | 137 +++++++++++++++- hw/arm/virt.c | 5 + hw/loongarch/acpi-build.c | 3 +- include/hw/acpi/aml-build.h | 20 ++- 5 files changed, 467 insertions(+), 8 deletions(-) diff --git a/hw/acpi/aml-build.c b/hw/acpi/aml-build.c index 15a6bc644a..c1d3fa1700 100644 --- a/hw/acpi/aml-build.c +++ b/hw/acpi/aml-build.c @@ -1964,6 +1964,203 @@ void build_slit(GArray *table_data, BIOSLinker *linker, MachineState *ms, acpi_table_end(linker, &table); } +static bool cache_described_at(MachineState *ms, CpuTopologyLevel level) +{ + if (machine_get_cache_topo_level(ms, CACHE_LEVEL_AND_TYPE_L3) == level || + machine_get_cache_topo_level(ms, CACHE_LEVEL_AND_TYPE_L2) == level || + machine_get_cache_topo_level(ms, CACHE_LEVEL_AND_TYPE_L1I) == level || + machine_get_cache_topo_level(ms, CACHE_LEVEL_AND_TYPE_L1D) == level) { + return true; + } + + return false; +} + +static int partial_cache_description(MachineState *ms, ACPIPPTTCache* caches, + int num_caches) +{ + int level, c; + + for (level = 1; level < num_caches; level++) { + for (c = 0; c < num_caches; c++) { + if (caches[c].level != level) { + continue; + } + + switch (level) { + case 1: + /* + * L1 cache is assumed to have both L1I and L1D available. + * Technically both need to be checked. + */ + if (machine_get_cache_topo_level(ms, + CACHE_LEVEL_AND_TYPE_L1I) == + CPU_TOPOLOGY_LEVEL_DEFAULT) + { + assert(machine_get_cache_topo_level(ms, + CACHE_LEVEL_AND_TYPE_L1D) == + CPU_TOPOLOGY_LEVEL_DEFAULT); + return level; + } + break; + case 2: + if (machine_get_cache_topo_level(ms, CACHE_LEVEL_AND_TYPE_L2) == + CPU_TOPOLOGY_LEVEL_DEFAULT) { + return level; + } + break; + case 3: + if (machine_get_cache_topo_level(ms, CACHE_LEVEL_AND_TYPE_L3) == + CPU_TOPOLOGY_LEVEL_DEFAULT) { + return level; + } + break; + } + } + } + + return 0; +} + +/* + * This function assumes l3 and l2 have unified cache and l1 is split l1d + * and l1i, and further prepares the lowest cache level for a topology + * level.
