![]() - Add support for the the Platform Firmware Runtime Update and Telemetry (PFRUT) interface based on ACPI to allow certain pieces of the platform firmware to be updated without restarting the system and to provide a mechanism for collecting platform firmware telemetry data (Chen Yu, Dan Carpenter, Yang Yingliang). - Ignore E820 reservations covering PCI host bridge windows on sufficiently recent x86 systems to avoid issues with allocating PCI BARs on systems where the E820 reservations cover the entire PCI host bridge memory window returned by the _CRS object in the system's ACPI tables (Hans de Goede). - Fix and clean up acpi_scan_init() (Rafael Wysocki). - Add more sanity checking to ACPI SPCR tables parsing (Mark Langsdorf). - Fix up ACPI APD (AMD Soc) driver initialization (Jiasheng Jiang). - Drop unnecessary "static" from the ACPI PCC address space handling driver added recently (kernel test robot). -----BEGIN PGP SIGNATURE----- iQJGBAABCAAwFiEE4fcc61cGeeHD/fCwgsRv/nhiVHEFAmHlrTwSHHJqd0Byand5 c29ja2kubmV0AAoJEILEb/54YlRxQ00QAI3CYIyM+TtgxOkun/DQdHEtLOXxVsQG V9p9zNa0xFjQY2fE3wwa4r03fg/AfM+qqOdgZDg2QnUlHVx+ZqzNlxMVnYz2QK3P lhZUJ2sX0ziAYC5AJFP44mcU4yAFgqGgUgv6VUGdoG2khngKA5ds1qYPqdNMigGr lfAoro2tVpKL66czvglBM6Af0RIrZvmh5dpwtja1tfquAy2qLOLfwBIafdFjrTS8 nVckdBNTgd12BxMaTlEIr8ZKX9Qe/YI0s+avzLc/lMI8gBlG0ZkGczDHxjLE48iE ZHwttNJm6PKR6Sj5AwXjswkW0n0aqVz1BbeDgdeL9zB6WbH9+EQaQFqYIc1pNyGG f67c8YwGFPMGx3BKdTksFESKb6DZifc1zbye3OKLxQquaWmufmhmQDVuXZzcfRO3 dkhIngX/sieEWwj1P1WdaDO4vC2zG2devJhxu3WGV8HCAHsZUoBduUwk+YZUVyp3 y+imobCCGEKZnHxtqJg7+VnQnH8ZTHFgOyqGa0boI5M8Dkae+qCcPCRDxHNa7L+7 Hb1eCH5RbB4MKQj/dmf01vpy/Q3gZOMHOoOHyMWp+IveculjcCxOIVZN0YQizj+3 Nw+1dcJLM6iR21f63zOQkoOhoFchp88IDc1PJtJnZOvI49Q9YB/2HKQdBGn292ZL +e3TWGpsfaZW =I4UB -----END PGP SIGNATURE----- Merge tag 'acpi-5.17-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull more ACPI updates from Rafael Wysocki: "The most significant item here is the Platform Firmware Runtime Update and Telemetry (PFRUT) support designed to allow certain pieces of the platform firmware to be updated on the fly, among other things. Also important is the e820 handling change on x86 that should work around PCI BAR allocation issues on some systems shipping since 2019. The rest is just a handful of assorted fixes and cleanups on top of the ACPI material merged previously. Specifics: - Add support for the the Platform Firmware Runtime Update and Telemetry (PFRUT) interface based on ACPI to allow certain pieces of the platform firmware to be updated without restarting the system and to provide a mechanism for collecting platform firmware telemetry data (Chen Yu, Dan Carpenter, Yang Yingliang). - Ignore E820 reservations covering PCI host bridge windows on sufficiently recent x86 systems to avoid issues with allocating PCI BARs on systems where the E820 reservations cover the entire PCI host bridge memory window returned by the _CRS object in the system's ACPI tables (Hans de Goede). - Fix and clean up acpi_scan_init() (Rafael Wysocki). - Add more sanity checking to ACPI SPCR tables parsing (Mark Langsdorf). - Fix up ACPI APD (AMD Soc) driver initialization (Jiasheng Jiang). - Drop unnecessary "static" from the ACPI PCC address space handling driver added recently (kernel test robot)" * tag 'acpi-5.17-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: ACPI: PCC: pcc_ctx can be static ACPI: scan: Rename label in acpi_scan_init() ACPI: scan: Simplify initialization of power and sleep buttons ACPI: scan: Change acpi_scan_init() return value type to void ACPI: SPCR: check if table->serial_port.access_width is too wide ACPI: APD: Check for NULL pointer after calling devm_ioremap() x86/PCI: Ignore E820 reservations for bridge windows on newer systems ACPI: pfr_telemetry: Fix info leak in pfrt_log_ioctl() ACPI: pfr_update: Fix return value check in pfru_write() ACPI: tools: Introduce utility for firmware updates/telemetry ACPI: Introduce Platform Firmware Runtime Telemetry driver ACPI: Introduce Platform Firmware Runtime Update device driver efi: Introduce EFI_FIRMWARE_MANAGEMENT_CAPSULE_HEADER and corresponding structures |
