So when the time comes to XOR the stripe, only the\nbeginning and end of the array need be checked. We scan the array\nand any NULL spot will be field by pages-to-be-read.\n\nThe FS that wants to support RAID5 needs to supply an\noperations-vector that searches a given page in cache, and specifies\nif the page is uptodate or need reading. All these pages to be read\nare put on a slave ore_io_state and synchronously read. All the pages\nof a stripe are read in one IO, using the scatter gather mechanism.\n\nIn write we constrain our IO to only be incomplete on a single\nstripe. Meaning either the complete IO is within a single stripe so\nwe might have pages to read from both beginning or end of the\nstrip. Or we have some reading to do at beginning but end at strip\nboundary. The left over pages are pushed to the next IO by the API\nalready established by previous work, where an IO offset/length\ncombination presented to the ORE might get the length truncated and\nthe user must re-submit the leftover pages. (Both exofs and NFS\nsupport this)\n\nBut any ORE user should make it\u0027s best effort to align it\u0027s IO\nbefore hand and avoid complications.

The three-stage commands do not have a data transfer and\nare handled without hardware assistance in raw frame mode.\n\nstage1: transmit host-to-device fis to notify the device of an incoming\natapi cdb. Upon reception of the pio-setup-fis repost the task_context\nto perform the dma transfer of the cdb+data (go to stage3), or repost\nthe task_context to transmit the cdb as a raw frame (go to stage 2).\n\nstage2: wait for hardware notification of the cdb transmission and then\ngo to stage 3.\n\nstage3: wait for the arrival of the terminating device-to-host fis and\nterminate the command.\n\nTo keep the implementation simple we only support ATAPI packet-dma\nprotocol (for commands with data) to avoid needing to handle the data\ntransfer manually (like we do for SATA-PIO). This may affect\ncompatibility for a small number of devices (see\nATA_HORKAGE_ATAPI_MOD16_DMA).\n\nIf the data-transfer underruns, or encounters an error the\ndevice-to-host fis is expected to arrive in the unsolicited frame queue\nto pass to libata for disposition.
