      ssb: Fix usage of struct device used for DMAing · 4ac58469
      Michael Buesch authored
      
      
      This fixes DMA on architectures where DMA is nontrivial, like PPC64.
      We must use the host-device's (PCI) struct device for any DMA
      operation instead of the SSB device. For this we add a new
      struct device pointer to the SSB device structure that will always
      point to the right device for DMAing.
      
      Without this patch b43 and b44 drivers won't work on complex-DMA
      architectures, that for example need dev->archdata for DMA operations.

      b43: Add PIO support for PCMCIA devices · 5100d5ac
      Michael Buesch authored
      
      
      This adds PIO support back (D'oh!) for PCMCIA devices.
      This is a complete rewrite of the old PIO code. It does actually work
      and we get reasonable performance out of it on a modern machine.
      On a PowerBook G4 I get a few MBit for TX and a few more for RX.
      So it doesn't work as well as DMA (of course), but it's a _lot_ faster
      than the old PIO code (only got a few kBit with that).
      
      The limiting factor is the host CPU speed. So it will generate 100%
      CPU usage when the network interface is heavily loaded. A voluntary preemption
      point in the RX path makes sure Desktop Latency isn't hurt.
      
      PIO is needed for 16bit PCMCIA devices, as we really don't want to poke with
      the braindead DMA mechanisms on PCMCIA sockets. Additionally, not all
      PCMCIA sockets do actually support DMA in 16bit mode (mine doesn't).
