df2798bc - dax/hmem: Move HMAT and Soft reservation probe initcall level

Fri, 10 Feb 2023 09:06:51 +0000

dax/hmem: Move HMAT and Soft reservation probe initcall levelIn preparation for moving more filtering of "hmem" ranges into thedax_hmem.ko module, update the initcall levels. HMAT range registrationmoves to subsys_initcall() to be done before Soft Reservation probing,and Soft Reservation probing is moved to device_initcall() to be donebefore dax_hmem.ko initialization if it is built-in.Tested-by: Fan Ni Reviewed-by: Vishal Verma Reviewed-by: Dave Jiang Link: https://lore.kernel.org/r/167602001107.1924368.11562316181038595611.stgit@dwillia2-xfh.jf.intel.comSigned-off-by: Dan Williams List of files: /linux-6.15/drivers/dax/hmem/Makefile

5ccac54f - ACPI: HMAT: attach a device for each soft-reserved range

Tue, 13 Oct 2020 23:49:28 +0000

ACPI: HMAT: attach a device for each soft-reserved rangeThe hmem enabling in commit cf8741ac57ed ("ACPI: NUMA: HMAT: Register"soft reserved" memory as an "hmem" device") only registered ranges to thehmem driver for each soft-reservation that also appeared in the HMAT.While this is meant to encourage platform firmware to "do the right thing"and publish an HMAT, the corollary is that platforms that fail to publishan accurate HMAT will strand memory from Linux usage. Additionally, the"efi_fake_mem" kernel command line option enabling will strand memory bydefault without an HMAT.Arrange for "soft reserved" memory that goes unclaimed by HMAT entries tobe published as raw resource ranges for the hmem driver to consume.Include a module parameter to disable either this fallback behavior, orthe hmat enabling from creating hmem devices. The module parameterrequires the hmem device enabling to have unique name in the modulenamespace: "device_hmem".The driver depends on the architecture providing phys_to_target_node()which is only x86 via numa_meminfo() and arm64 via a generic memblockimplementation.[joao.m.martins@oracle.com: require NUMA_KEEP_MEMINFO for phys_to_target_node()] Link: https://lkml.kernel.org/r/aaae71a7-4846-f5cc-5acf-cf05fdb1f2dc@oracle.comSigned-off-by: Dan Williams Signed-off-by: Joao Martins Signed-off-by: Andrew Morton Reviewed-by: Joao Martins Cc: Jonathan Cameron Cc: Brice Goglin Cc: Jeff Moyer Cc: Catalin Marinas Cc: Will Deacon Cc: Andy Lutomirski Cc: Ard Biesheuvel Cc: Benjamin Herrenschmidt Cc: Ben Skeggs Cc: Borislav Petkov Cc: Daniel Vetter Cc: Dave Hansen Cc: Dave Jiang Cc: David Airlie Cc: David Hildenbrand Cc: Greg Kroah-Hartman Cc: "H.

c01044cc - ACPI: HMAT: refactor hmat_register_target_device to hmem_register_device

Tue, 13 Oct 2020 23:49:13 +0000

ACPI: HMAT: refactor hmat_register_target_device to hmem_register_deviceIn preparation for exposing "Soft Reserved" memory ranges without an HMAT,move the hmem device registration to its own compilation unit and make theimplementation generic.The generic implementation drops usage acpi_map_pxm_to_online_node() thatwas translating ACPI proximity domain values and instead relies onnuma_map_to_online_node() to determine the numa node for the device.[joao.m.martins@oracle.com: CONFIG_DEV_DAX_HMEM_DEVICES should depend on CONFIG_DAX=y] Link: https://lkml.kernel.org/r/8f34727f-ec2d-9395-cb18-969ec8a5d0d4@oracle.comSigned-off-by: Dan Williams Signed-off-by: Joao Martins Signed-off-by: Andrew Morton Cc: Andy Lutomirski Cc: Benjamin Herrenschmidt Cc: Ben Skeggs Cc: Borislav Petkov Cc: Brice Goglin Cc: Catalin Marinas Cc: Daniel Vetter Cc: Dave Hansen Cc: Dave Jiang Cc: David Airlie Cc: David Hildenbrand Cc: Greg Kroah-Hartman Cc: "H.
