and XMITS has to be basically done in the same manner as for the Sabres, i.e. only for devices behind PCI-PCI-bridges and after a PIO read on the far side of the farest PCI-PCI-bridge. Given that the Tomatillo documentation mentions no difference to the Schizo bridges in this regard and this is also still part of the procedure described Schizo documentation this seems about right so adjust accordingly (the unconditional CDMA flushing/syncing previously done was based on how Linux behaves). - Implement CDMA flushing/syncing for Schizo version >= 5, which requires the workaround described in Schizo Errata I-23. According to Schizo Errata I-13 it's just unusable with version < 5 though. [1] - Don't register the Schizo streaming buffer for now until it's usage is sorted out according to the erratas. - Register our interrupt filters with the revived INTR_FAST so they these interrupts can even interrupt filters of device drivers as necessary. - Remove the comment regarding lack of newbus'ified bus_dma(9) as being able to associate a DMA tag with a device would allow to implement CDMA flushing/syncing in bus_dmamap_sync(9) but that would totally kill performance. Given that for devices not behind a PCI-PCI bridge the host-to-PCI bridges also only do CDMA flushing/syncing based on interrupts there's no additional disadvantage for polling(4) callbacks in the case schizo(4) has to do the CDMA flushing/syncing but rather a general problem.
