I tested it myself now with VT6306 on PPC32. > it should be triggered by replacing > &fw_high_memory_region > by > &fw_private_region > in drivers/firewire/fw-sbp2.c and testing with any SBP-2 device This indeed demonstrates the fix. Any IO to SBP-2 devices fails with timeouts. Just removing the posted write enable bit in fw-ohci wasn't sufficient to catch it though. Maybe the controller has write posting enabled by default. However, this endianess bug was low-profile because there are currently no kernelspace or userspace drivers for the firewire stack which need to respond in split transactions. -- Stefan Richter -=====-==--- --== ----= http://arcgraph.de/sr/ _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
