BROADCOM ha scritto:BUILD AND INSTALLATION INSTRUCTIONS
-----------------------------------
hybrid-portsrc-x86_32-v5_10_91_9.tar.gz
hybrid-portsrc-x86_64-v5_10_91_9.tar.gz
On the target machine, setup the source/hybrid/build directory
1. Create a new directory: mkdir hybrid_wl
2. Go to that directory: cd hybrid_wl
3. Untar the appropriate 32/64 bit file
to that directory
32 bit: tar -xzf <path>/hybrid-portsrc-x86_32-v5_10_91_9.tar.gz
64 bit: tar -xzf <path>/hybrid-portsrc-x86_64-v5_10_91_9.tar.gz
After untar'ing you should have a src and lib sub directory plus a Linux
2.6 "kbuild" external makefile (Makefile). The lib sub directory has the pre-built
binary, wlc_hybrid.o_shipped.
You use the standard Linux 2.6 kernel build system as follows to make a Linux loadable
kernel module (LKM):
On the target machine, and cd'ed to the directory that contains the Makefile (fragment)
4. Cleanup (optional): make -C /lib/modules/<2.6.xx.xx>/build M=`pwd` clean
5. Build the LKM, i.e. wl.ko: make -C /lib/modules/<2.6.xx.xx>/build M=`pwd`
You should now have a LKM, wl.ko inside this directory.
On this or a machine with the same kernel version, install the driver.
1. Validate you don't have loaded (or built into the kernel) the Linux community provided
driver for Broadcom hardware. This exists in two forms: either "bcm43xx" or a split form
of "b43" plus "b43legacy". If these modules were loaded you would either
a) rmmod bcm43xx or
b) rmmod b43; rmmod b43legacy
1a. Validate you don't have a older wl.ko driver loaded from previous install.
If the module exist, remove it and replace with new driver:
a) rmmod wl.ko
2. Replacing existing driver with wl.ko just build in step 5 above.
(most likely path to find wl.ko is: /lib/modules/<kernel_version>/kernel/driver/net/wireless
or /lib/modules/<kernel_version>/kernel.net/update/)
3. depmod
4. modprobe wl
Some kernels come with a pre-installed Broadcom driver that supports Broadcom's 43xx family of
PCIE cards. If the kernel supports one of those pre-installed driver, you must remove it in order
to install the new driver. Some of the existing drivers provided by the Linux community that support
Broadcom hardware are b43/b43legacy/bcm43xx. There is also a ssb driver that is loaded along with
b43. This ssb driver also must be removed.
If the kernel supports blacklist, you can add those drivers to the blacklist file so that it will
not be loaded on next reboot.
