Merge tag 'cxl-for-6.8' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl
Pull CXL (Compute Express Link) updates from Dan Williams:
"The bulk of this update is support for enumerating the performance
capabilities of CXL memory targets and connecting that to a platform
CXL memory QoS class. Some follow-on work remains to hook up this data
into core-mm policy, but that is saved for v6.9.
The next significant update is unifying how CXL event records (things
like background scrub errors) are processed between so called
"firmware first" and native error record retrieval. The CXL driver
handler that processes the record retrieved from the device mailbox is
now the handler for that same record format coming from an EFI/ACPI
notification source.
This also contains miscellaneous feature updates, like Get Timestamp,
and other fixups.
Summary:
- Add support for parsing the Coherent Device Attribute Table (CDAT)
- Add support for calculating a platform CXL QoS class from CDAT data
- Unify the tracing of EFI CXL Events with native CXL Events.
- Add Get Timestamp support
- Miscellaneous cleanups and fixups"
