Title: KVM CLX ACPI HMAT table support Status in linux package in Ubuntu: Expired Bug description: ACPI HMAT table support : HMAT is a new ACPI table that records the performance parameter of memory, so MCDRAM (or next gen HBM2) can be described well by this table. We need to support this table in kernel and qemu so that guest can get and parse this table then to find where the high-performance memory is. Heterogeneous Memory Attribute Table (HMAT) describes the memory attributes, such as memory side cache attributes and bandwidth and latency details, related to the System Physical Address (SPA) Memory Ranges. The software is expected to use this information as hint for optimization. HMAT is defined in ACPI 6.2: 5.2.27 Heterogeneous Memory Attribute Table (HMAT). http://www.uefi.org/sites/default/files/resources/ACPI_6_2.pdf patches: http://lists.nongnu.org/archive/html/qemu-devel/2018-06/msg05368.html To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1782212/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
