6251d380 - ACPI: ARM Performance Monitoring Unit Table (APMT) initial support

Thu, 29 Sep 2022 00:28:34 +0000

ACPI: ARM Performance Monitoring Unit Table (APMT) initial supportARM Performance Monitoring Unit Table describes the properties of PMUsupport in ARM-based system. The APMT table contains a list of nodes,each represents a PMU in the system that conforms to ARM CoreSight PMUarchitecture. The properties of each node include information requiredto access the PMU (e.g. MMIO base address, interrupt number) and alsoidentification. For more detailed information, please refer to thespecification below: * APMT: https://developer.arm.com/documentation/den0117/latest * ARM Coresight PMU: https://developer.arm.com/documentation/ihi0091/latestThe initial support adds the detection of APMT table and genericinfrastructure to create platform devices for ARM CoreSight PMUs.Similar to IORT the root pointer of APMT is preserved during runtimeand each PMU platform device is given a pointer to the correspondingAPMT node.Signed-off-by: Besar Wicaksono Acked-by: Rafael J.

5f1ae4eb - acpi/arm64: Add GTDT table parse driver

Fri, 31 Mar 2017 17:51:01 +0000

acpi/arm64: Add GTDT table parse driverThis patch adds support for parsing arch timer info in GTDT,provides some kernel APIs to parse all the PPIs andalways-on info in GTDT and export them.By this driver, we can simplify arm_arch_timer drivers, andseparate the ACPI GTDT knowledge from it.Signed-off-by: Fu Wei Signed-off-by: Hanjun Guo Acked-by: Rafael J.

88ef16d8 - ACPI: I/O Remapping Table (IORT) initial support

Mon, 12 Sep 2016 18:54:20 +0000

ACPI: I/O Remapping Table (IORT) initial supportIORT shows representation of IO topology for ARM based systems.It describes how various components are connected together onparent-child basis e.g. PCI RC -> SMMU -> ITS. Also see IORT spec.http://infocenter.arm.com/help/topic/com.arm.doc.den0049b/DEN0049B_IO_Remapping_Table.pdfInitial support allows to detect IORT table presence and save itsroot pointer obtained through acpi_get_table(). The pointer validitydepends on acpi_gbl_permanent_mmap because if acpi_gbl_permanent_mmapis not set while using IORT nodes we would dereference unmapped pointers.For the aforementioned reason call acpi_iort_init() from acpi_init()which guarantees acpi_gbl_permanent_mmap to be set at that point.Add generic helpers which are helpful for scanning and retrievinginformation from IORT table content. List of the most important helpers:- iort_find_dev_node() finds IORT node for a given device- iort_node_map_rid() maps device RID and returns IORT node which provides final translationIORT support is placed under drivers/acpi/arm64/ new directory due to itsARM64 specific nature. The code there is considered only for ARM64.The long term plan is to keep all ARM64 specific tables supportin this place e.g. GTDT table.Signed-off-by: Tomasz Nowicki Acked-by: Rafael J.
