Marvell 88W8686 chipset (connected over SDIO)
Information about a Linux Kernel module
modinfo sd8xxx
filename: /lib/modules/2.6.24-palm-joplin-3430/kernel/net/wifi/sd8xxx.ko license: GPL author: Marvell International Ltd. description: M-WLAN Driver srcversion: 533BB7E5866E52F63B9ACCB depends: vermagic: 2.6.24-palm-joplin-3430 mod_unload ARMv7 parm: param_sd_slot_selector:int parm: param_sdio_bus_width:int parm: param_use_sdio_irq:int parm: helper_name:charp parm: fw_name:charp parm: mfgmode:int
The sd8xxx driver is open source (although it requires proprietary firmware) and available under the GPL. But why is it not on palm's open source packages site? Where is the source? Didn't find it under http://opensource.palm.com/1.1.3/index.html
The original Marvell GPL sources are published in this download: http://www.marvell.com/drivers/driverDisplay.do?driverId=203 however the palm modifications to these sources do not appear to be published (morphis: wrote an email to Palm to get their modifications if they have some)
Exploring the /proc/net/wlan
cat /proc/net/wlan/info
driver_name = "wlan" driver_version = sd8686-9.15.14-26409.p62-(FP4) InterfaceName="eth0" ...
Exploring Kernel configuration
cat /boot/config-2.6.24-palm-joplin-3430

CONFIG_LIBERTAS is not set ???
