This pause will allow us to configure\n the FCoE Controller before enabling it.\n\n2) Makes the \u0027mode\u0027 attribute of a fcoe_ctlr_device\n writale.

Indeed, I don\u0027t know of any devices\nthat don\u0027t handle READ CAPACITY(10) properly.\n\nTherefore this patch (as1559) adds a new flag telling the sd driver\nto try READ CAPACITY(10) before READ CAPACITY(16), and sets this flag\nfor every USB mass-storage device.

These structures are transferred from\nmain memory to the controller using a set of register commands; these\ncommands include setting up the context (\"posting\"), removing the\ncontext (\"invalidating\"), and commands to control the scheduling of\ncommands and connections to that remote device (\"suspensions\" and\n\"resumptions\"). There is a similar path to control RNC scheduling from\nthe protocol engine, which interprets the results of command and data\ntransmission and reception.\n\nIn general, the controller chooses among non-suspended RNCs to find one\nthat has work requiring scheduling the transmission of command and data\nframes to a target. Likewise, when a target tries to return data back\nto the initiator, the state of the RNC is used by the controller to\ndetermine how to treat the incoming request. As an example, if the RNC\nis in the state \"TX/RX Suspended\", incoming SSP connection requests from\nthe target will be rejected by the controller hardware. When an RNC is\n\"TX Suspended\", it will not be selected by the controller hardware to\nstart outgoing command or data operations (with certain priority-based\nexceptions).\n\nAs mentioned above, there are two sources for management of the RNC\nstates: commands from driver software, and the result of transmission\nand reception conditions of commands and data signaled by the controller\nhardware. As an example of the latter, if an outgoing SSP command ends\nwith a OPEN_REJECT(BAD_DESTINATION) status, the RNC state will\ntransition to the \"TX Suspended\" state, and this is signaled by the\ncontroller hardware in the status to the completion of the pending\ncommand as well as signaled in a controller hardware event. Examples of\nthe former are included in the patch changelogs.\n\nDriver software is required to suspend the RNC in a \"TX/RX Suspended\"\ncondition before any outstanding commands can be terminated. Failure to\nguarantee this can lead to a complete hardware hang condition. Earlier\nversions of the driver software did not guarantee that an RNC was\ncorrectly managed before I/O termination, and so operated in an unsafe\nway.\n\nFurther, the driver performed unnecessary contortions to preserve the\nremote device command state and so was more complicated than it needed\nto be. A simplifying driver assumption is that once an I/O has entered\nthe error handler path without having completed in the target, the\nrequirement on the driver is that all use of the sas_task must end.\nBeyond that, recovery of operation is dependent on libsas and other\ncomponents to reset, rediscover and reconfigure the device before normal\noperation can restart. In the driver, this simplifying assumption meant\nthat the RNC management could be reduced to entry into the suspended\nstate, terminating the targeted I/O request, and resuming the RNC as\nneeded for device-specific management such as an SSP Abort Task or LUN\nReset Management request.\n" }, { "commit": "c79dd80d73017a88a2c2ae46e7d5303cba6a32e0", "tree": "4bf1f09df72921272e38bc0c9610374d4c1873e2", "parents": [ "11cc51835af0e6fbb2da9cb012bdaaa036497b7f" ], "author": { "name": "Dan Williams", "email": "dan.j.williams@intel.com", "time": "Wed Feb 01 00:44:14 2012 -0800" }, "committer": { "name": "Dan Williams", "email": "dan.j.williams@intel.com", "time": "Thu May 17 12:27:11 2012 -0700" }, "message": "isci: kill sci_phy_protocol and sci_request_protocol\n\nHoldovers from the initial driver cleanup, replace with enum sas_protocol.\n\nSigned-off-by: Dan Williams \u003cdan.j.williams@intel.com\u003e\n" }, { "commit": "2177199d5150cf61bf26badcb6901176cc13787b", "tree": "d6fc1da211354f6601959ecb6fc7d2a704b1b039", "parents": [ "605c6cd201714535e2723a60197228050f863a8f" ], "author": { "name": "John Soni Jose", "email": "sony.john-n@emulex.com", "time": "Tue Apr 03 23:41:49 2012 -0500" }, "committer": { "name": "James Bottomley", "email": "JBottomley@Parallels.com", "time": "Wed Apr 25 09:29:35 2012 +0100" }, "message": "[SCSI] be2iscsi: Get Initiator Name for the iSCSI_Host\n\nImplement the ISCSI_HOST_PARAM_INITIATOR_NAME for .get_host_param\n\nSigned-off-by: John Soni Jose \u003csony.john-n@emulex.com\u003e\nSigned-off-by: Jayamohan Kallickal \u003cjayamohan.kallickal@emulex.com\u003e\nSigned-off-by: Mike Christie \u003cmichaelc@cs.wisc.edu\u003e\nSigned-off-by: James Bottomley \u003cJBottomley@Parallels.com\u003e\n" }, { "commit": "b2024459252a9d2d312ee562f86f332a1498f412", "tree": "751987779eee44a601a68c766ba2ff258b77d25a", "parents": [ "0f3fce5cc77e1f35758ef0e46a989e76e5046a7b" ], "author": { "name": "Dan Williams", "email": "dan.j.williams@intel.com", "time": "Wed Mar 21 21:09:07 2012 -0700" }, "committer": { "name": "James Bottomley", "email": "JBottomley@Parallels.com", "time": "Mon Apr 23 12:11:47 2012 +0100" }, "message": "[SCSI] libsas, libata: fix start of life for a sas ata_port\n\nThis changes the ordering of initialization and probing events from:\n 1/ allocate rphy in PORTE_BYTES_DMAED, DISCE_REVALIDATE_DOMAIN\n 2/ allocate ata_port and schedule port probe in DISCE_PROBE\n...to:\n 1/ allocate ata_port in PORTE_BYTES_DMAED, DISCE_REVALIDATE_DOMAIN\n 2/ allocate rphy in PORTE_BYTES_DMAED, DISCE_REVALIDATE_DOMAIN\n 3/ schedule port probe in DISCE_PROBE\n\nThis ordering prevents PHYE_SIGNAL_LOSS_EVENTS from sneaking in to\ndestrory ata devices before they have been fully initialized:\n\n BUG: unable to handle kernel paging request at 0000000000003b10\n IP: [\u003cffffffffa0053d7e\u003e] sas_ata_end_eh+0x12/0x5e [libsas]\n ...\n [\u003cffffffffa004d1af\u003e] sas_unregister_common_dev+0x78/0xc9 [libsas]\n [\u003cffffffffa004d4d4\u003e] sas_unregister_dev+0x4f/0xad [libsas]\n [\u003cffffffffa004d5b1\u003e] sas_unregister_domain_devices+0x7f/0xbf [libsas]\n [\u003cffffffffa004c487\u003e] sas_deform_port+0x61/0x1b8 [libsas]\n [\u003cffffffffa004bed0\u003e] sas_phye_loss_of_signal+0x29/0x2b [libsas]\n\n...and kills the awkward \"sata domain_device briefly existing in the\ndomain without an ata_port\" state.\n\nReported-by: Michal Kosciowski \u003cmichal.kosciowski@intel.com\u003e\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": "22b9153faa2263aa89625de25e71c7d44c8dbd16", "tree": "1157d64a9c63c5b7b48b4a5b3610965d8d4c9624", "parents": [ "f8fc75dc576eac0c996e4a792a4701819d999260" ], "author": { "name": "Dan Williams", "email": "dan.j.williams@intel.com", "time": "Fri Mar 09 11:00:06 2012 -0800" }, "committer": { "name": "James Bottomley", "email": "JBottomley@Parallels.com", "time": "Mon Apr 23 12:03:39 2012 +0100" }, "message": "[SCSI] libsas: introduce sas_work to fix sas_drain_work vs sas_queue_work\n\nWhen requeuing work to a draining workqueue the last work instance may\nnot be idle, so sas_queue_work() must not touch work-\u003eentry.

As Tejun notes:\n\n \"For now, I think it would be best to add private wrapper in libsas to\n support deferring unchained work items while draining.\"\n\nSigned-off-by: Dan Williams \u003cdan.j.williams@intel.com\u003e\nSigned-off-by: James Bottomley \u003cJBottomley@Parallels.com\u003e\n" }, { "commit": "f8daa6e6d83f60a721752cb53433bfdc1503b45f", "tree": "66798b2d2763a53acada47040c86f7c094430f0a", "parents": [ "b15ebe0b5d0b95aeb1d84cae3649df1e0e065e9b" ], "author": { "name": "Dan Williams", "email": "dan.j.williams@intel.com", "time": "Mon Dec 19 17:02:25 2011 -0800" }, "committer": { "name": "James Bottomley", "email": "JBottomley@Parallels.com", "time": "Sun Feb 19 13:47:29 2012 -0600" }, "message": "[SCSI] libsas: convert ha-\u003estate to flags\n\nIn preparation for adding new states (SAS_HA_DRAINING, SAS_HA_FROZEN),\nconvert ha-\u003estate into a set of flags.\n\nSigned-off-by: Dan Williams \u003cdan.j.williams@intel.com\u003e\nSigned-off-by: James Bottomley \u003cJBottomley@Parallels.com\u003e\n" }, { "commit": "b15ebe0b5d0b95aeb1d84cae3649df1e0e065e9b", "tree": "ff93ad5f8be5fe91c7e6cf4963253491ddd058fb", "parents": [ "756f173fb5fa90ec15222e80fb579288be7794fd" ], "author": { "name": "Dan Williams", "email": "dan.j.williams@intel.com", "time": "Thu Nov 17 17:59:49 2011 -0800" }, "committer": { "name": "James Bottomley", "email": "JBottomley@Parallels.com", "time": "Sun Feb 19 13:41:04 2012 -0600" }, "message": "[SCSI] libsas: replace event locks with atomic bitops\n\nThe locks only served to make sure the pending event bitmask was updated\nconsistently.\n\nSigned-off-by: Dan Williams \u003cdan.j.williams@intel.com\u003e\nSigned-off-by: James Bottomley \u003cJBottomley@Parallels.com\u003e\n" } ], "next": "756f173fb5fa90ec15222e80fb579288be7794fd" }
