It covers flagging DCD support in the mailbox, reading the dynamic capacity configuration from the device, gathering DSMAS data for the DCD partitions, and configuring the dynamic capacity interrupts. It also adds a documentation update and a cleanup that enforces partition ordering. DCD is not enabled yet with these code changes. Patches are applied to reduce the whole set in order to relief the burden of very large patch set review. Zero sized HDM decoders are now allowed, along with cxl_test support for them. There is also a set of decoder hardening patches for switch decoder enumeration. Latency calculations now account for link width and use consistent units. The GPF timeout programming has been reworked. The pull also has a number of misc patches. A large number of bug fixes against pre-existing issues make up the rest of the pull. Many of these were flagged by review of patches posted to the mailing list by sashiko. Also adding Richard Cheng as a reviewer (R) to the CXL sub-system" * tag 'cxl-for-7.4' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl: (49 commits) cxl/events: Test CME counter expiry with equality, not bitwise AND Documentation/cxl: Document DPA partition layout and ordering rules cxl/core: Enforce partition order/simplify partition calls cxl/mem: Configure dynamic capacity interrupts cxl/pci: Factor out interrupt policy check cxl/events: Split event msgnum configuration from irq setup cxl/cdat: Gather DSMAS data for DCD partitions cxl/mem: Read dynamic capacity configuration from the device cxl/mbox: Flag support for Dynamic Capacity Devices (DCD) cxl/acpi: Convert QTG _DSM latencies to picoseconds cxl: Account for link width in latency calculation cxl/port: Convert PCIe link latency to nanoseconds cxl/pci: Update only the Port GPF timeout fields cxl/pci: Program the Port GPF timeouts before caching the DVSEC cxl/pci: Use the Device GPF DVSEC for restricted endpoints cxl/port: Attach endpoints to a dport under the lock that pins it cxl/core: Hold the dport host lock across dport lookup and use cxl/port: Clear cached dport pointers when a dport is removed cxl/region: Warn on user region position mismatch cxl/acpi: Check ACPI companion before use ... |
