2.6.32-git5+, CONFIG_WEXT_PRIV and Broadcom's driver for BCM4322 Wireless chips

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi all,

 I use Broadcom's out-of-tree driver which is the only one that works with
 my Dell E6400's onboard BCM4322 wireless chip - driver here

 http://www.broadcom.com/support/802.11/linux_sta.php

 and the driver stopped building somewhere between 2.6.32-git1 and -git5,
 as CONFIG_WIRELESS_EXT is now replaced by CONFIG_CFG80211_WEXT,
 but also as struct iw_handler_def (in <net/iw_handler.h>) has a few fields
 referenced by the driver that are now conditioned by CONFIG_WEXT_PRIV.

CONFIG_WEXT_PRIV isn't directly selectable during kernel config, but is
 rather picked up by wireless drivers via SELECT keywords in the Kconfig
 files - and this is my issue.

At the moment, after replacing all CONFIG_WIRELESS_EXT occurrences
 with CONFIG_CFG80211_WEXT in the Broadcom driver sources, I worked
 around the CONFIG_WEXT_PRIV issue by picking ipw2200 as a module
 in my kernel config - and ipw2200 is select'ing CONFIG_WEXT_PRIV; not
 an optimal solution, but this way my kernel has now support for a feature
 I do need later on when building the out-of-tree Broadcom module.

After rebooting into 2.6.32-git9 I successfully built the patched driver which
 loads fine and connects to my AP as usual - so the workaround seems ok.


But: what is the best option here to make CONFIG_WEXT_PRIV visible at
 kernel build time if only an external module should select it - but selection
 is not actually happening at kernel build time ?
Could CONFIG_WEXT_PRIV be made a separate user-selectable option ?


Thanks,
