[GIT PULL] Compute Express Link for 5.17

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi Linus, please pull from:

  git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl tags/cxl-for-5.17

...to receive the CXL update for v5.17. 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.

  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

      cxl/test: Mock acpi_table_parse_cedt()
      cxl/pmem: Fix module reload vs workqueue state

Ira Weiny (3):
