So where does that leave the lockdep rcu debugs setting in the kernel. Is that going to remain enabled for the release and thus blocking the Broadcom STA driver from loading ? of course, nothing stops anyone from doing a backport and adding the open source driver in the community OBS Nope, nothing stopping anyone from doing that and that's great for developers. But that's not going to satisfy the many regular users out there the the Netbook UX was designed for. Those on netbooks that have a Broadcom wifi chip, such as the Dell Mini 9 which I won or the Lenovo ideapad that was given out at the Meegoconf in dublin. At least they can at present, with the 1.1 release, get a Broadcom driver built and running on their netbooks, even if it's a convoluted process for them. I'd hate to see us loose that of force a situation where we're forcing a Broadcom driver to claim its GPL when it's not.

Shane... [1] http://slaine.org/_slaine/Meego_1.1_Wifi.html Actually, now I remember why I didn't post the update for this last week. The kernel as it ships with the 1.1.90 builds is blocking the Broadcom driver from loading indirectly. In order to remove the init_MUTEX code from the driver you have to include the semaphore headers and use sema_init func in init_MUTEX's place. However, the kernel has lockdep rcu debugging enabled which is strictly GPL and by including the semaphore.h, including the inline code. When you try and load the Wl module, which doesn't specify a license type or if it does should be 'Mixed/Proprietary', it 'taints' the kernel which then unloads the module. I'm not sure if this is a recent addition to the kernels in the 1.1.90 builds as I think just patching the init_MUTEX function out of the driver worked ok on the 1.1.80 builds. A work around is to have the wl module report it's license as GPL, but I'm not prepared to ship a source rpm that makes those modifications as that's just not right. So, either the MeeGo trunk kernels turn off lockdep rcu debugs or we all spend time making the opensource BCM driver work on 2.6.37 Given the proliferation of BCM chipsets out there, this is something that should be addressed prior to the 1.2 release. -- Glen Gray sla...@slaine.org ___ MeeGo-dev mailing list MeeGo-dev@meego.com http://lists.meego.com/listinfo/meego-dev
