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

2024-01-18T23:27:22+00:00

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.

vm_object: Modify various drivers to allocate OBJT_SWAP objects

2022-07-27T13:50:51+00:00

This is in preparation for removal of OBJT_DEFAULT.  In particular, it
is now cheap to check whether an OBJT_SWAP object has any swap blocks
allocated, so the benefit of having a separate OBJT_DEFAULT type is
quite marginal, and the OBJT_DEFAULT->SWAP transition is a source of
bugs.

Adjust agp_find_device() definition in agp.c to avoid clang 15 warning

2022-07-19T18:02:06+00:00

With clang 15, the following -Werror warning is produced:

    sys/dev/agp/agp.c:910:16: error: a function declaration without a prototype is deprecated in all versions of C [-Werror,-Wstrict-prototypes]
    agp_find_device()
                   ^
                    void

This is because agp_find_device() is declared with a (void) argument
list, and defined with an empty argument list. Make the definition match
the declaration.
