The highlight is initial support for CXL memory hotplug. The static NUMA node (ACPI SRAT Physical Address to Proximity Domain) information known to platform firmware is extended to support the potential performance-class / memory-target nodes dynamically created from available CXL memory device capacity. New unit test infrastructure is added for validating health information payloads. Fixes to module reload stress and stack usage from exposure in -next are included. A symbol rename and some other miscellaneous fixups are included as well. This has been in -next for several weeks with no reported issues / conflicts. --- The following changes since commit fa55b7dcdc43c1aa1ba12bca9d2dd4318c2a0dbf: Linux 5.16-rc1 (2021-11-14 13:56:52 -0800) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl tags/cxl-for-5.17 for you to fetch changes up to be185c2988b48db65348d94168c793bdbc8d23c3: cxl/core: Remove cxld_const_init in cxl_decoder_alloc() (2022-01-04 17:29:31 -0800) ---------------------------------------------------------------- cxl for 5.17 - Rework ACPI sub-table infrastructure to optionally be used outside of __init scenarios and use it for CEDT.CFMWS sub-table parsing. - Add support for extending num_possible_nodes by the potential hotplug CXL memory ranges - Extend tools/testing/cxl with mock memory device health information - Fix a module-reload workqueue race - Fix excessive stack-frame usage - Rename the driver context data structure from "cxl_mem" since that name collides with a proposed driver name - Use EXPORT_SYMBOL_NS_GPL instead of -DDEFAULT_SYMBOL_NAMESPACE at build time ---------------------------------------------------------------- Alison Schofield (1): ACPI: NUMA: Add a node and memblk for each CFMWS not in SRAT Dan Williams (8): cxl/pmem: Fix reference counting for delayed work cxl/core: Convert to EXPORT_SYMBOL_NS_GPL ACPI: Keep sub-table parsing infrastructure available for modules ACPI: Teach ACPI table parsing about the CEDT header format ACPI: Add a context argument for table parsing handlers cxl/acpi: Convert CFMWS parsing to ACPI sub-table helpers cxl/test: Mock acpi_table_parse_cedt() cxl/pmem: Fix module reload vs workqueue state Ira Weiny (3): cxl/mbox: Remove bad comment cxl/memdev: Change cxl_mem to a more descriptive name cxl/memdev: Remove unused cxlmd field Nathan Chancellor (1): cxl/core: Remove cxld_const_init in cxl_decoder_alloc() Vishal Verma (1): tools/testing/cxl: add mock output for the GET_HEALTH_INFO command drivers/acpi/Kconfig | 3 + drivers/acpi/numa/srat.c | 59 ++++++++++- drivers/acpi/tables.c | 87 ++++++++++++---- drivers/cxl/Kconfig | 1 + drivers/cxl/acpi.c | 237 ++++++++++++++++-------------------------- drivers/cxl/core/Makefile | 2 +- drivers/cxl/core/bus.c | 26 +++-- drivers/cxl/core/mbox.c | 186 ++++++++++++++++----------------- drivers/cxl/core/memdev.c | 55 +++++----- drivers/cxl/core/pmem.c | 20 ++-- drivers/cxl/core/regs.c | 8 +- drivers/cxl/cxl.h | 10 +- drivers/cxl/cxlmem.h | 37 ++++--- drivers/cxl/pci.c | 120 ++++++++++----------- drivers/cxl/pmem.c | 85 ++++++++++----- include/linux/acpi.h | 34 ++++-- tools/testing/cxl/Kbuild | 3 +- tools/testing/cxl/test/cxl.c | 68 ++++++++---- tools/testing/cxl/test/mem.c | 99 +++++++++++++----- tools/testing/cxl/test/mock.c | 30 ++---- tools/testing/cxl/test/mock.h | 6 +- 21 files changed, 675 insertions(+), 501 deletions(-)
