* bwn(4): migrate bwn(4) to the native bhnd(9) interface, and drop siba_bwn.Landon J. Fuller2018-02-051-1/+6
| | | | | | | | | | | | | - 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.Landon J. Fuller2017-12-021-1/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Approved by: adrian (mentor, implicit) Sponsored by: The FreeBSD Foundation & Plausible Labs Differential Revision: https://reviews.freebsd.org/D13041 Notes: svn path=/head/; revision=326454

* [bwn] add in bwn n-phy linking.Adrian Chadd2016-05-171-0/+13
| | | | | | | | | | | | | | | | | | | | | | | * 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.

* [bwn] break out the 'g' phy code into a separate source file.Adrian Chadd2016-05-021-1/+3
| | | | | | | | | | | | | * Break out the 'g' phy code; * Break out the debugging bits into a separate source file, since some debugging prints are done in the phy code; * Make some more chip methods in if_bwn.c public. This brings the size of if_bwn.c down to 6,805 lines which is now approaching managable. Notes: svn path=/head/; revision=298948
* [bwn] break out the LP PHY code into a separate file.Adrian Chadd2016-05-021-0/+1
| | | | | | | | | | | | This (and eventually migrating the other PHY code out) is in preparation for adding the 11n PHY. No, the 11ac PHY (for the BCM4260 softmac part) isn't yet open source, so we can't grow that. Yet. This trims ~3,700 lines of code from if_bwn.c, bringing it down to a slightly less crazy sounding 10,446 lines of code. Notes: svn path=/head/; revision=298944

Also, always use -Wno-unknown-pragma to (hopefully temporarily) work around #pragma ident in debug.h in the opensolaris code. Remove some stale warning suppression that's no longer necessary.

* adds bwn(4) driver for supporting Broadcom BCM43xx chipsets.Weongyo Jeong2010-02-161-0/+9
o uses v4 firmware instead of v3. A port will be committed to create the bwn firmware module. o supports B/G and LP(low power) PHYs. o supports 32 / 64 bits DMA operations. o tested on big / little endian machines so should work on all architectures. It'd not connected to the build until the firmware port is committed. Notes: svn path=/head/; revision=203945
