X-Received-From: 192.55.52.136 Subject: [Qemu-devel] [PATCH v10 00/11] Build ACPI Heterogeneous Memory Attribute Table (HMAT) X-BeenThere: qemu-devel@nongnu.org X-Mailman-Version: 2.1.23 Precedence: list List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Cc: jingqi.liu@intel.com, tao3.xu@intel.com, fan.du@intel.com, qemu-devel@nongnu.org, daniel@linux.ibm.com, jonathan.cameron@huawei.com, dan.j.williams@intel.com Errors-To: qemu-devel-bounces+patchwork-qemu-devel=patchwork.kernel.org@nongnu.org Sender: "Qemu-devel" This series of patches will build Heterogeneous Memory Attribute Table (HMAT) according to the command line. The ACPI HMAT describes the memory attributes, such as memory side cache attributes and bandwidth and latency details, related to the Memory Proximity Domain. The software is expected to use HMAT information as hint for optimization. In the linux kernel, the codes in drivers/acpi/hmat/hmat.c parse and report the platform's HMAT tables. These patches depend on: https://patchwork.kernel.org/project/qemu-devel/list/?series=166701 The V9 patches link: https://patchwork.kernel.org/cover/11085475/ Changelog: v10: - Add qemu_strtotime_ps() to convert strings with time suffixes to numbers, and add some tests for it. - Add qapi buildin type time, and add some tests for it. - Add machine oprion properties "-machine hmat=on|off" for enabling or disabling HMAT in QEMU. v9: - change the CLI input way, make it more user firendly (Daniel Black) use latency=NUM[p|n|u]s and bandwidth=NUM[M|G|P](B/s) as input and drop the base-lat and base-bw input. v8: - rebase to upstream - Add check if numa->numa_state is NULL in pxb_dev_realize_common - Use nb_nodes in spapr_populate_memory() (RESEND to fix) (Igor) Liu Jingqi (5): hmat acpi: Build Memory Proximity Domain Attributes Structure(s) hmat acpi: Build System Locality Latency and Bandwidth Information Structure(s) hmat acpi: Build Memory Side Cache Information Structure(s) numa: Extend CLI to provide memory latency and bandwidth information numa: Extend CLI to provide memory side cache information Tao Xu (6): util/cutils: Add qemu_strtotime_ps() tests/cutils: Add test for qemu_strtotime_ps() qapi: Add builtin type time tests: Add test for QAPI builtin type time numa: Extend CLI to provide initiator information for numa nodes tests/bios-tables-test: add test cases for ACPI HMAT hw/acpi/Kconfig | 5 + hw/acpi/Makefile.objs | 1 + hw/acpi/hmat.c | 256 +++++++++++++++++++++++++++++ hw/acpi/hmat.h | 103 ++++++++++++ hw/core/machine.c | 72 ++++++++ hw/core/numa.c | 242 +++++++++++++++++++++++++++ hw/i386/acpi-build.c | 3 + include/qapi/visitor-impl.h | 4 + include/qapi/visitor.h | 9 + include/qemu/cutils.h | 1 + include/qemu/typedefs.h | 2 + include/sysemu/numa.h | 39 +++++ qapi/machine.json | 182 +++++++++++++++++++- qapi/opts-visitor.c | 22 +++ qapi/qapi-visit-core.c | 12 ++ qapi/qobject-input-visitor.c | 18 ++ qapi/trace-events | 1 + qemu-options.hx | 96 ++++++++++- scripts/qapi/common.py | 2 + tests/bios-tables-test.c | 44 +++++ tests/test-cutils.c | 199 ++++++++++++++++++++++ tests/test-keyval.c | 125 ++++++++++++++ tests/test-qobject-input-visitor.c | 29 ++++ util/cutils.c | 82 +++++++++ 24 files changed, 1540 insertions(+), 9 deletions(-) create mode 100644 hw/acpi/hmat.c create mode 100644 hw/acpi/hmat.h
