1) sgiwd93 used to switch off asynchronous mode on the wd33c93, discarding any "nosync"-requests from the commandline. But we need to allow "nosync"-requests for selected devices, for example the Pioneer DVD305S. (For the curious: this device accepts the SDTR from wd33c93 and success- fully sends inquiry data in sync mode, but after the data phase in the inquiry command does an unexpected disconnect, seemingly sending no "status" or "command complete". Forcing async transfers makes it work together flawlessly with the wd33c93. Of course, preferable would be, to implement wd33c93's "resume command" stuff, but that probably will not come soon.) 2) Maximize benefit from the preceding Fast SCSI patch for wd33c93 by passing the higher input-clock frequency explicitely. To be applied after the mentioned wd33c93 patch. with kind regards Signed-off-by: peter fuerst <post@xxxxxxxx> ======================================================================== --- dc7bdc97927ea1c519f0d8bd3133739600c841d4/drivers/scsi/sgiwd93.c Sat Oct 7 00:00:00 2006 +++ new/drivers/scsi/sgiwd93.c Sun Feb 11 22:10:06 2007 @@ -250,3 +250,3 @@ - hdata->wh.no_sync = 0; + if (0xff == hdata->wh.no_sync) hdata->wh.no_sync = 0; ======================================================================== ======================================================================== --- dc7bdc97927ea1c519f0d8bd3133739600c841d4/drivers/scsi/sgiwd93.c Sat Oct 7 00:00:00 2006 +++ stage2/drivers/scsi/sgiwd93.c Sun Feb 11 22:10:06 2007 @@ -248,3 +248,3 @@ - wd33c93_init(host, regs, dma_setup, dma_stop, WD33C93_FS_16_20); + wd33c93_init(host, regs, dma_setup, dma_stop, WD33C93_FS_MHZ(20)); ======================================================================== - To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
