staging: brcm80211: revised README
Browse files Browse the repository at this point in the history
Removed duplicated text sections in README. Removed Bugs/problems that no longer
occur. One brcmsmac instability remains, (to be solved with new ucode), that has
been moved to the TODO file.

Broadcom Mac80211 driver
Broadcom brcmsmac (mac80211-based softmac PCIe) and brcmfmac (SDIO) drivers.

Firmware installation
======================
Firmware is available from the Linux firmware repository at:
Completely open source host drivers, no binary object files.

git://git.kernel.org/pub/scm/linux/kernel/git/dwmw2/linux-firmware.git
http://git.kernel.org/?p=linux/kernel/git/dwmw2/linux-firmware.git
https://git.kernel.org/?p=linux/kernel/git/dwmw2/linux-firmware.git
Support for the following chips:
===============================

For all chips, copy brcm/bcm43xx-0.fw and brcm/bcm43xx_hdr-0.fw to
/lib/firmware/brcm (or wherever firmware is normally installed on your system).
brcmsmac (PCIe)
Name Device ID
BCM4313 0x4727
BCM43224 0x4353
BCM43225 0x4357

Currently supported chips
==============
PCI
Name Device ID
BCM4313 0x4727
BCM43224 0x4353
BCM43225 0x4357
brcmfmac (SDIO)
Name
BCM4329

Both brcmsmac and brcmfmac drivers require firmware files that need to be
separately downloaded.

Bugs/Problems
==============
- Driver can get confused while scanning during high throughput, can cause
burping, hanging, and possible crashing.
- Occasional hangs & burps with BCM43224 on 2.4 GHz with dual stream rates.
- Occasional crashes with BCM43224 on multicore machines.

Firmware
======================
Firmware is available from the Linux firmware repository at:

Broadcom fullmac driver
git://git.kernel.org/pub/scm/linux/kernel/git/dwmw2/linux-firmware.git
http://git.kernel.org/?p=linux/kernel/git/dwmw2/linux-firmware.git
https://git.kernel.org/?p=linux/kernel/git/dwmw2/linux-firmware.git

This is production driver.

What's here
===========
- Completely open source host driver, no binary object files
- Features Broadcom's OneDriver architecture (single source base for
supported chips and architectures)
- On-chip firmware loaded using standard request_firmware()
- Support for BCM4329(SDIO)
===============================================================
Broadcom brcmsmac driver
===============================================================
- Support for both 32 and 64 bit Linux kernels

What's done
==========
- Integration with cfg80211 stack
- Most of Mac functionality is performed in dongle
- A-MPDU single stream rates
- BCM4329: Dualband, Single stream, 20MHz channels

Firmware installation
======================
Firmware is available from the Linux firmware repository at:
Copy brcm/bcm43xx-0.fw and brcm/bcm43xx_hdr-0.fw to
/lib/firmware/brcm (or wherever firmware is normally installed
on your system).


===============================================================
Broadcom brcmfmac driver
===============================================================
- Support for 32 bit Linux kernel, 64 bit untested

git://git.kernel.org/pub/scm/linux/kernel/git/dwmw2/linux-firmware.git
http://git.kernel.org/?p=linux/kernel/git/dwmw2/linux-firmware.git
https://git.kernel.org/?p=linux/kernel/git/dwmw2/linux-firmware.git

For 4329 chip, copy brcm/bcm4329-fullmac-4.bin and brcm/bcm4329-fullmac-4.txt
Firmware installation
======================
Copy brcm/bcm4329-fullmac-4.bin and brcm/bcm4329-fullmac-4.txt
to /lib/firmware/brcm (or wherever firmware is normally installed on your
system).
