In message <200101131529.f0DFTps26367@aslan.scsiguy.com> "Justin T. Gibbs" writes: : RF_SHARABLE requests to share a resource with another device, not : within the same device. Further, RF_SHARABLE only applies to : IRQs, not BARs. Actaully, the underlying RF_SHARABLE is for any region of resource that can be multiplexed between different devices. However, in practice, only IRQs can be shared. And even then the device drive would only be working around bugs in the bridge drivers that don't enable sharing.
