The HAL is provided in a binary-only form in order to -comply with local regulatory agency rules. In the United States -the FCC requires that a radio transmitter only be operated at power -levels and on frequency channels for which it is approved. The FCC -requires that a software-defined radio cannot be configured by a -user to operate outside the approved power levels and frequency -channels. This makes it difficult to open-source code that enforces -limits on the power levels, frequency channels and other parameters -of the radio transmitter. See - -http://ftp.fcc.gov/Bureaus/Engineering_Technology/Orders/2001/fcc01264.pdf - -for the specific FCC regulation. Because the module is provided -in a binary-only form it is marked "Proprietary" on Linux; this -means when you load it you will see messages that your system is -now "tainted". - -If you wish to use this driver on a platform for which an ath_hal -module is not already provided please contact the author. Note that -this is only necessary for new _architectures_; the HAL is not tied to -any specific version of your operating system. - - -Atheros Hardware -================ -There are many generations of Atheros 802.11 wireless devices that -are typically referred to by their programming model: - -5210 supports 11a only -5211 supports both 11a and 11b -5212 supports 11a, 11b, and 11g - -These parts have been incorporated in a variety of retail products -including cardbus cards and mini-pci cards. In addition many laptop -vendors use Atheros mini-pci cards for their builtin wireless -support. - -The Atheors PCI vendor id is 0x168c. The file ah_devid.h lists most -known PCI device id's but is not exhaustive. Some vendors program -their own vendor and/or device id's to aid in BIOS-locking mini-pci -cards in laptops. - -Atheros SoC Hardware -==================== -In addition to the cardbus/pci devices Atheros makes System on Chip -(SoC) parts that integrate a MIPS cpu core and one or more MAC and -radio parts. Binary support for these parts is necessarily built -for the embedded MIPS processor where the code is to be run. - -Caveats -======= -The binary hal builds provided here include no floating point and -are operating system-independent. However due to toolchain -peculiarities the .o files may be wrongly rejected by development -tools. If that happens it may be possible to patch the file header -so that the native toolchain will accept the files. In particular -this has been observed for various Linux MIPS installations for the -SoC parts. If you have issues consult the associated .inc file in -the public directory; it explains exactly how the binary file was -created (e.g. toolchain and compilation options). |
