bwn(4): Fix outstanding bug in PHY-G tssi2dbm table generation caught by

-Wconstant-conversion, and remove now unnecessary warning suppression flags.

bwn(4): migrate bwn(4) to the native bhnd(9) interface, and drop siba_bwn.

2018-02-05T23:38:15Z

- Remove the shim interface that allowed bwn(4) to use either siba_bwn or bhnd(4), replacing all siba_bwn calls with their bhnd(4) bus equivalents. - Drop the legay, now-unused siba_bwn bus driver. - Clean up bhnd(4) board flag defines referenced by bwn(4).

Introduce bwn(4) support for the bhnd(4) bus.

2017-12-02T02:21:27Z

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: ... 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 Approved by: adrian (mentor, implicit) Sponsored by: The FreeBSD Foundation & Plausible Labs Differential Revision: https://reviews.freebsd.org/D13041

[bwn] add in bwn n-phy linking.

2016-05-17T07:15:25Z

* The default kernel and options won't build the GPL PHY bits; * bwn(4) defaults to building as a module anyway!; * If BWN_GPL_PHY is specified in the config file, and you uncomment the GPL PHY bits in the module Makefile, you'll get a working N-PHY. This is specifically designed to be obtuse for now, as I don't want to flip it on by default. It's easy enough for people to flip on and build, and it's a module so the default GENERIC kernel won't be GPL tainted. I'll have to add an actual HAL layer that allows the GPL PHY to be loaded before if_bwn so it can be "magic", but that'll come later. Tested: * BCM4321 11abg NIC, STA mode
