Thanks # to PeterZ for setting me straight on the current capabilities of the # lockdep API, and Greg acked it as well. # # On the CXL ACPI side this update adds support for CXL _OSC so that # platform firmware knows that it is safe to still grant Linux native # control of PCIe hotplug and error handling in the presence of CXL # devices. A circular dependency problem was discovered between suspend # and CXL memory for cases where the suspend image might be stored in # CXL memory where that image also contains the PCI register state to # restore to re-enable the device. Disable suspend for now until an # architecture is defined to clarify that conflict. # # Lastly a collection of reworks, fixes, and cleanups to the CXL # subsystem where support for snooping mailbox commands and properly # handling the "mem_enable" flow are the highlights. # # Summary: # # - Add driver-core infrastructure for lockdep validation of # device_lock(), and fixup a deadlock report that was previously # hidden behind the 'lockdep no validate' policy. # # - Add CXL _OSC support for claiming native control of CXL hotplug and # error handling. # # - Disable suspend in the presence of CXL memory unless and until a # protocol is identified for restoring PCI device context from memory # hosted on CXL PCI devices. # # - Add support for snooping CXL mailbox commands to protect against # inopportune changes, like set-partition with the 'immediate' flag # set. # # - Rework how the driver detects legacy CXL 1.1 configurations (CXL # DVSEC / 'mem_enable') before enabling new CXL 2.0 decode # configurations (CXL HDM Capability). # # - Miscellaneous cleanups and fixes from -next exposure" # # * tag 'cxl-for-5.19' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl: (47 commits) #
