Subject: [PATCH v3 09/10] acpi/numa/hmat: Register HMAT at device_initcall level
Date: Fri, 07 Jun 2019 12:28:01 -0700 [thread overview]
Message-ID: <155993568120.3036719.6635543389090509374.stgit@dwillia2-desk3.amr.corp.intel.com> (raw)
In-Reply-To: <155993563277.3036719.17400338098057706494.stgit@dwillia2-desk3.amr.corp.intel.com>
In preparation for registering device-dax instances for accessing EFI
specific-purpose memory, arrange for the HMAT registration to occur
later in the init process. Critically HMAT initialization needs to occur
after e820__reserve_resources_late() which is the point at which the
iomem resource tree is populated with "Application Reserved"
(IORES_DESC_APPLICATION_RESERVED). e820__reserve_resources_late()
happens at subsys_initcall time.
