The two stage atapi\ncommands are those that include a dma data transfer. The data transfer\nportion of these operations is handled by the hardware packet-dma\nacceleration. 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. However, in the DONE_UNEXP_FIS (data\nunderrun) case it appears we need to craft a response. In the\nDONE_REG_ERR case we do receive the UF and propagate it to libsas.\n\nSigned-off-by: Maciej Trela \u003cmaciej.trela@intel.com\u003e\nSigned-off-by: Dan Williams \u003cdan.j.williams@intel.com\u003e\nSigned-off-by: James Bottomley \u003cJBottomley@Parallels.com\u003e\n" }, { "commit": "bb041a0e9c31229071b6e56e1d0d8374af0d2038", "tree": "5dd6587870627a58b85c2e2f1aa8618ce3fffd75", "parents": [ "d962480e9a061505637bb16543d49e247349e25d" ], "author": { "name": "Jack Wang", "email": "jack_wang@usish.com", "time": "Fri Sep 23 14:32:32 2011 +0800" }, "committer": { "name": "James Bottomley", "email": "JBottomley@Parallels.com", "time": "Sun Oct 02 12:51:06 2011 -0500" }, "message": "[SCSI] libsas: set sas_address and device type of rphy\n\nLibsas forget to set the sas_address and device type of rphy lead to file\nunder /sys/class/sas_x show wrong value, fix that.\n\nSigned-off-by: Jack Wang \u003cjack_wang@usish.com\u003e\nTested-by: Crystal Yu \u003ccrystal_yu@usish.com\u003e\nCc: stable@kernel.org\nSigned-off-by: James Bottomley \u003cJBottomley@Parallels.com\u003e\n" }, { "commit": "97a1420d127ca1db2fd665707bf4e9501758147c", "tree": "4d89c37ee1e55ec98b733bc968a0896c0a1985e8", "parents": [ "f6e67035a9edd79b8b202c159d5bec560bb9c358" ], "author": { "name": "Dan Williams", "email": "dan.j.williams@intel.com", "time": "Tue Sep 20 15:10:46 2011 -0700" }, "committer": { "name": "James Bottomley", "email": "JBottomley@Parallels.com", "time": "Sun Oct 02 12:36:43 2011 -0500" }, "message": "[SCSI] libsas: dynamic queue depth\n\nThe queue-depth for libsas-attached devices initializes to 32 and can\nonly be increased manually via sysfs to a max of 64, while mpt2sas\nattached devices initialize to 254 and dynamically float via the\nmidlayer -\u003echange_queue_depth interface.\n\nNo performance regression was observed with this change on the isci\ndriver.\n\nTested-by: Dave Jiang \u003cdave.jiang@intel.com\u003e\nSigned-off-by: Dan Williams \u003cdan.j.williams@intel.com\u003e\nSigned-off-by: James Bottomley \u003cJBottomley@Parallels.com\u003e\n" }, { "commit": "f6e67035a9edd79b8b202c159d5bec560bb9c358", "tree": "ba884b5a2de7cb60bd1e6f67813b47fdb8ff509a", "parents": [ "2fc62e2ac350b8f574e0a09170b350a8f2fa4a02" ], "author": { "name": "Dan Williams", "email": "dan.j.williams@intel.com", "time": "Tue Sep 20 15:10:33 2011 -0700" }, "committer": { "name": "James Bottomley", "email": "JBottomley@Parallels.com", "time": "Sun Oct 02 12:30:30 2011 -0500" }, "message": "[SCSI] libsas,libata: fix -\u003echange_queue_{depth|type} for sata devices\n\nPass queue_depth change requests to libata, and prevent queue_type\nchanges for ATA devices.\n\nOtherwise:\n1/ we do not honor the libata specific restrictions on the queue depth\n2/ libsas drivers that do not set sdev-\u003etagged_supported are unable to\n change the queue_depth of ata devices via sysfs\n\nSigned-off-by: Dan Williams \u003cdan.j.williams@intel.com\u003e\nAcked-by: Jeff Garzik \u003cjgarzik@redhat.com\u003e\nSigned-off-by: James Bottomley \u003cJBottomley@Parallels.com\u003e\n" }, { "commit": "ffaac8f45bfb2dffb78179baa5740de34058eef8", "tree": "653f9eae24129d54ce4df0a67bc883ed16d93dac", "parents": [ "41e9a69641fb3fa86fa9277a179f3ad261d072f7" ], "author": { "name": "Luben Tuikov", "email": "ltuikov@yahoo.com", "time": "Thu Sep 22 09:41:36 2011 -0700" }, "committer": { "name": "James Bottomley", "email": "JBottomley@Parallels.com", "time": "Sun Oct 02 12:23:11 2011 -0500" }, "message": "[SCSI] libsas: Allow expander T-T attachments\n\nAllow expander table-to-table attachments for\nexpanders that support it.\n\nSigned-off-by: Luben Tuikov \u003cltuikov@yahoo.com\u003e\nSigned-off-by: James Bottomley \u003cJBottomley@Parallels.com\u003e\n" }, { "commit": "8ec6552f4a77d15f446b00aed364e3c12d38aa6c", "tree": "efaa0dfc6479d28a14e5e778e8eb246ff94c360f", "parents": [ "9c224ac21506d29f5a6ff4df0c4cc9f97484fa25" ], "author": { "name": "Dan Williams", "email": "dan.j.williams@intel.com", "time": "Thu Sep 01 21:18:20 2011 -0700" }, "committer": { "name": "James Bottomley", "email": "JBottomley@Parallels.com", "time": "Thu Sep 22 14:59:09 2011 +0400" }, "message": "[SCSI] libsas: sgpio write support\n\nAdd SFF-8485 v0.7 / SAS-1 smp-write-gpio register support to libsas.\nDefer SAS-2 support unless/until it defines an sgpio interface.\n\nMinimum implementation needed to get the lights blinking.\ntry_test_sas_gpio_gp_bit() provides a common method to parse the\nincoming write data (raw bitstream), and the to_sas_gpio_gp_bit() helper\nroutine can be used as a basis for the set/clear operations for the\n\u0027read\u0027 implementation.

No locking or other behavior should change\nwith this patch. All existing bugs and locking orders are preserved.\n\nAdditionally, add one parameter to queuecommand,\n\tstruct Scsi_Host *\nand remove one parameter from queuecommand,\n\tvoid (*done)(struct scsi_cmnd *)\n\nScsi_Host* is a convenient pointer that most host drivers need anyway,\nand \u0027done\u0027 is redundant to struct scsi_cmnd-\u003escsi_done.\n\nMinimal code disturbance was attempted with this change. Most drivers\nneeded only two one-line modifications for their host lock push-down.\n\nSigned-off-by: Jeff Garzik \u003cjgarzik@redhat.com\u003e\nAcked-by: James Bottomley \u003cJames.Bottomley@suse.de\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "c70b5296e775cde46cfcb2d860ba160108a5ec7a", "tree": "30419cb982acca44499236adcca65f2f87698c74", "parents": [ "80c226fbef56576946c9655fcb2ab62e63404d12", "58ff4bd042adf8013c8f70fd03c2c0f8d022e387" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Oct 22 17:34:15 2010 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Oct 22 17:34:15 2010 -0700" }, "message": "Merge git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi-misc-2.6\n\n* git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi-misc-2.6: (84 commits)\n [SCSI] be2iscsi: SGE Len \u003d\u003d 64K\n [SCSI] be2iscsi: Remove premature free of cid\n [SCSI] be2iscsi: More time for FW\n [SCSI] libsas: fix bug for vacant phy\n [SCSI] sd: Fix overflow with big physical blocks\n [SCSI] st: add MTWEOFI to write filemarks without flushing drive buffer\n [SCSI] libsas: Don\u0027t issue commands to devices that have been hot-removed\n [SCSI] megaraid_sas: Add Online Controller Reset to MegaRAID SAS drive\n [SCSI] lpfc 8.3.17: Update lpfc driver version to 8.3.17\n [SCSI] lpfc 8.3.17: Replace function reset methodology\n [SCSI] lpfc 8.3.17: SCSI fixes\n [SCSI] lpfc 8.3.17: BSG fixes\n [SCSI] lpfc 8.3.17: SLI Additions and Fixes\n [SCSI] lpfc 8.3.17: Code Cleanup and Locking fixes\n [SCSI] zfcp: Remove scsi_cmnd-\u003eserial_number from debug traces\n [SCSI] ipr: fix array error logging\n [SCSI] aha152x: enable PCMCIA on 64bit\n [SCSI] scsi_dh_alua: Handle all states correctly\n [SCSI] cxgb4i: connection and ddp setting update\n [SCSI] cxgb3i: fixed connection over vlan\n ...\n" }, { "commit": "2bc72c91ea7e104b0e40151543d135b933a12e93", "tree": "50e5d393a70882ed513dbc402b82c1f1d2216fcc", "parents": [ "526f7c7950bbf1271e59177d70d74438c2ef96de" ], "author": { "name": "Jack Wang", "email": "jack_wang@usish.com", "time": "Wed Oct 06 16:05:35 2010 +0800" }, "committer": { "name": "James Bottomley", "email": "James.Bottomley@suse.de", "time": "Mon Oct 11 17:40:00 2010 -0500" }, "message": "[SCSI] libsas: fix bug for vacant phy\n\nThis patch fix bug reported by Chuck.
