At present, only HD() device types are supported (both GPT and
MBR). CdRom and floppy devices aren't supported. ZFS isn't supported
because there's no way in the UEFI standard to specify a ZFS datastore.
Network devices aren't supported either.
Three forms of Unix path are accepted: /path/to/file (for a mounted
filesystem), //path/to/file (uses the EFI partition on the same disk
as /), and dev:/path/to/file (for unmounted filesystem). Two forms are
produced (the first and last).

Currently, bwn(4) relies on the siba_bwn(4) bus driver to provide support
for the on-chip SSB interconnect found in Broadcom's older PCI(e) Wi-Fi
adapters. Non-PCI Wi-Fi adapters, as well as the newer BCMA interconnect
found in post-2009 Broadcom Wi-Fi hardware, are not supported by
siba_bwn(4).
The bhnd(4) bus driver (also used by the FreeBSD/MIPS Broadcom port)
provides a unified kernel interface to a superset of the hardware supported
by siba_bwn; by attaching bwn(4) via bhnd(4), we can support both modern
PCI(e) Wi-Fi devices based on the BCMA backplane interconnect, as well as
Broadcom MIPS WiSoCs that include a D11 MAC core directly attached to their
SSB or BCMA backplane.
This diff introduces opt-in bwn(4) support for bhnd(4) by providing:
- A small bwn(4) driver subclass, if_bwn_bhnd, that attaches via
bhnd(4) instead of siba_bwn(4).
- A bhndb(4)-based PCI host bridge driver, if_bwn_pci, that optionally
probes at a higher priority than the siba_bwn(4) PCI driver.
- A set of compatibility shims that perform translation of bwn(4)'s
siba_bwn function calls into their bhnd(9) API equivalents when bwn(4)
is attached via a bhnd(4) bus parent. When bwn(4) is attached via
siba_bwn(4), all siba_bwn function calls are simply passed through to
their original implementations.
To test bwn(4) with bhnd(4), place the following lines in loader.conf(5):
hw.bwn_pci.preferred="1"
if_bwn_pci_load="YES
bwn_v4_ucode_load="YES"
bwn_v4_lp_ucode_load="YES"
To verify that bwn(4) is using bhnd(4), you can check dmesg:
bwn0: <Broadcom 802.11 MAC/PHY/Radio, rev 15> ... on bhnd0
... or devinfo(8):
pcib2
pci2
bwn_pci0
bhndb0
bhnd0
bwn0
...
bwn(4)/bhnd(4) has been tested for regressions with most chipsets currently
supported by bwn(4), including:
- BCM4312
- BCM4318
- BCM4321
With minimal changes to the DMA code (not included in this commit), I was
also able to test support for newer BCMA devices by bringing up basic
working Wi-Fi on two previously unsupported, BCMA-based N-PHY chipsets:
- BCM43224
- BCM43225

The Display Interface Unit (DIU) uses main memory for the framebuffer, which
is already mapped as cache coherent physical memory. Prevent mmap() from
using its own attributes which may otherwise conflict.
- Add missing call to device_delete_children() in bhndb_detach(), without
which we're left with stale child devices on module unload.
- Pass the parent PCI device to pci_release_msi(), not the bhndb_pci(4)
child.

bhnd_chipc's children may hold strong provider references to their parent;
we must detach any children before attempting to deregister the bhnd_chipc
