So I looked closer at the code now. The b43legacy 64bit DMA code certainly is dead, unused and broken code. One could remove it, if someone really cares (I don't). However, there is another issue. b43legacy calls ssb_dma_translation() (also on 30/32bit code) for every descriptor. As our ssb patch adds a SSB register read to ssb_dma_translation(), this adds an unacceptable amount of overhead. This needs to be addressed before merging the ssb patch. _______________________________________________ b43-dev mailing list [email protected] http://lists.infradead.org/mailman/listinfo/b43-dev
