pci_cfgreg: Add a PCI domain argument to the low-level register API

2024-01-18T22:44:51Z

This commit changes the API of pci_cfgreg(read|write) to add a domain argument (referred to as a segment in ACPI parlance) (note that this is not the same as a NUMA domain, but something PCI-specific). This does not yet enable access to domains other than 0, but updates the API to support domains. Places that use hard-coded bus/slot/function addresses have been updated to hardcode a domain of 0. A few places that have the PCI domain (segment) available such as the acpi_pcib_acpi.c Host-PCI bridge driver pass the PCI domain. The hpt27xx(4) and hptnr(4) drivers fail to attach to a device not on domain 0 since they provide APIs to their binary blobs that only permit bus/slot/function addressing. The x86 non-ACPI PCI bus drivers all hardcode a domain of 0 as they do not support multiple domains.

Extract eventfilter declarations to sys/_eventfilter.h

2019-05-20T00:38:23Z

This allows replacing "sys/eventfilter.h" includes with "sys/_eventfilter.h" in other header files (e.g., sys/{bus,conf,cpu}.h) and reduces header pollution substantially. EVENTHANDLER_DECLARE and EVENTHANDLER_LIST_DECLAREs were moved out of .c files into appropriate headers (e.g., sys/proc.h, powernv/opal.h). As a side effect of reduced header pollution, many .c files and headers no longer contain needed definitions. The remainder of the patch addresses adding appropriate includes to fix those files. LOCK_DEBUG and LOCK_FILE_LINE_ARG are moved to sys/_lock.h, as required by sys/mutex.h since r326106 (but silently protected by header pollution prior to this change). No functional change (intended). Of course, any out of tree modules that relied on header pollution for sys/eventhandler.h, sys/lock.h, or sys/mutex.h inclusion need to be fixed. __FreeBSD_version has been bumped.

ichwd: add a few assertions about tco_version

2018-12-18T17:17:53Z

Those should ensure correctness of ichwd_find_ich_lpc_bridge() and ichwd_find_ich_lpc_bridge() as well as make it easier for both humans and static analyzers to see the relation between tco_version and ich and smb variables in ichwd_identify().
