X-Git-Tag: v5.10.7~1443 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=cf1d2b44f6c701ffff58606b5b8a8996190d6e7d;p=platform%2Fkernel%2Flinux-rpi.git Merge tag 'acpi-5.10-rc1' of git://git./linux/kernel/git/rafael/linux-pm Pull ACPI updates from Rafael Wysocki: "These add support for generic initiator-only proximity domains to the ACPI NUMA code and the architectures using it, clean up some non-ACPICA code referring to debug facilities from ACPICA, reduce the overhead related to accessing GPE registers, add a new DPTF (Dynamic Power and Thermal Framework) participant driver, update the ACPICA code in the kernel to upstream revision 20200925, add a new ACPI backlight whitelist entry, fix a few assorted issues and clean up some code. Specifics: - Add support for generic initiator-only proximity domains to the ACPI NUMA code and the architectures using it (Jonathan Cameron) - Clean up some non-ACPICA code referring to debug facilities from ACPICA that are not actually used in there (Hanjun Guo) - Add new DPTF driver for the PCH FIVR participant (Srinivas Pandruvada) - Reduce overhead related to accessing GPE registers in ACPICA and the OS interface layer and make it possible to access GPE registers using logical addresses if they are memory-mapped (Rafael Wysocki) - Update the ACPICA code in the kernel to upstream revision 20200925 including changes as follows: + Add predefined names from the SMBus sepcification (Bob Moore) + Update acpi_help UUID list (Bob Moore) + Return exceptions for string-to-integer conversions in iASL (Bob Moore) + Add a new "ALL " debugger command (Bob Moore) + Add support for 64 bit risc-v compilation (Colin Ian King) + Do assorted cleanups (Bob Moore, Colin Ian King, Randy Dunlap) - Add new ACPI backlight whitelist entry for HP 635 Notebook (Alex Hung) - Move TPS68470 OpRegion driver to drivers/acpi/pmic/ and split out Kconfig and Makefile specific for ACPI PMIC (Andy Shevchenko) - Clean up the ACPI SoC driver for AMD SoCs (Hanjun Guo) - Add missing config_item_put() to fix refcount leak (Hanjun Guo) - Drop lefrover field from struct acpi_memory_device (Hanjun Guo) - Make the ACPI extlog driver check for RDMSR failures (Ben Hutchings) - Fix handling of lid state changes in the ACPI button driver when input device is closed (Dmitry Torokhov) - Fix several assorted build issues (Barnabás Pőcze, John Garry, Nathan Chancellor, Tian Tao) - Drop unused inline functions and reduce code duplication by using kobj_to_dev() in the NFIT parsing code (YueHaibing, Wang Qing) - Serialize tools/power/acpi Makefile (Thomas Renninger)" * tag 'acpi-5.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (64 commits) ACPICA: Update version to 20200925 Version 20200925 ACPICA: Remove unnecessary semicolon ACPICA: Debugger: Add a new command: "ALL " ACPICA: iASL: Return exceptions for string-to-integer conversions ACPICA: acpi_help: Update UUID list ACPICA: Add predefined names found in the SMBus sepcification ACPICA: Tree-wide: fix various typos and spelling mistakes ACPICA: Drop the repeated word "an" in a comment ACPICA: Add support for 64 bit risc-v compilation ACPI: button: fix handling lid state changes when input device closed tools/power/acpi: Serialize Makefile ACPI: scan: Replace ACPI_DEBUG_PRINT() with pr_debug() ACPI: memhotplug: Remove 'state' from struct acpi_memory_device ACPI / extlog: Check for RDMSR failure ACPI: Make acpi_evaluate_dsm() prototype consistent docs: mm: numaperf.rst Add brief description for access class 1. node: Add access1 class to represent CPU to memory characteristics ACPI: HMAT: Fix handling of changes from ACPI 6.2 to ACPI 6.3 ACPI: Let ACPI know we support Generic Initiator Affinity Structures x86: Support Generic Initiator only proximity domains ... --- cf1d2b44f6c701ffff58606b5b8a8996190d6e7d diff --cc drivers/acpi/numa/hmat.c index 134bcb4,6ea95b36..cb73a5d --- a/drivers/acpi/numa/hmat.c +++ b/drivers/acpi/numa/hmat.c @@@ -635,12 -678,72 +685,12 @@@ static void hmat_register_target_cache( node_add_cache(mem_nid, &tcache->cache_attrs);
