There\n is single host link but if a PMP is attached to it, there can be\n multiple fan-out links. On SATA, there\u0027s usually a single device\n connected to a link but PATA and SATA controllers emulating TF based\n interface can have two - master and slave.\n\n However, there are a few controllers which don\u0027t fit into this\n abstraction too well - SATA controllers which emulate TF interface\n with both master and slave devices but also have separate SCR\n register sets for each device. These controllers need separate links\n for physical link handling (e.g. onlineness, link speed) but should\n be treated like a traditional M/S controller for everything else\n (e.g. command issue, softreset).\n\n slave_link is libata\u0027s way of handling this class of controllers\n without impacting core layer too much. For anything other than\n physical link handling, the default host link is used for both master\n and slave. For physical link handling, separate @ap-\u003eslave_link is\n used. All dirty details are implemented inside libata core layer.\n From LLD\u0027s POV, the only difference is that prereset, hardreset and\n postreset are called once more for the slave link, so the reset\n sequence looks like the following.\n\n prereset(M) -\u003e prereset(S) -\u003e hardreset(M) -\u003e hardreset(S) -\u003e\n softreset(M) -\u003e postreset(M) -\u003e postreset(S)\n\n Note that softreset is called only for the master. Softreset resets\n both M/S by definition, so SRST on master should handle both (the\n standard method will work just fine).\n\nAs slave_link excludes PMP support and only code paths which deal with\nthe attributes of physical link are affected, all the changes are\nlocalized to libata.h, libata-core.c and libata-eh.c.\n\n * ata_is_host_link() updated so that slave_link is considered as host\n link too.\n\n * iterator extended to iterate over the slave_link when using the\n underbarred version.\n\n * force param handling updated such that devno 16 is mapped to the\n slave link/device.\n\n * ata_link_on/offline() updated to return the combined result from\n master and slave link. ata_phys_link_on/offline() are the direct\n versions.\n\n * EH autopsy and report are performed separately for master slave\n links. Reset is udpated to implement the above described reset\n sequence.\n\nExcept for reset update, most changes are minor, many of them just\nmodifying dev-\u003elink to ata_dev_phys_link(dev) or using phys online\ntest instead.\n\nAfter this update, LLDs can take full advantage of per-dev SCR\nregisters by simply turning on slave link.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nSigned-off-by: Jeff Garzik \u003cjgarzik@redhat.com\u003e\n" }, { "commit": "b5b3fa386b8f96c7fa92e507e5deddc2637924b4", "tree": "2d203860958d43b430974bcf365f4d8d3aa36b24", "parents": [ "aadffb682cc5572f48cc24883681db65530bd284" ], "author": { "name": "Tejun Heo", "email": "tj@kernel.org", "time": "Thu Jul 31 17:02:42 2008 +0900" }, "committer": { "name": "Jeff Garzik", "email": "jgarzik@redhat.com", "time": "Mon Sep 29 00:22:32 2008 -0400" }, "message": "libata: misc updates to prepare for slave link\n\n* Add ATA_EH_ALL_ACTIONS.\n\n* Make sata_link_{on|off}_line() return bool instead of int.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nSigned-off-by: Jeff Garzik \u003cjgarzik@redhat.com\u003e\n" }, { "commit": "aadffb682cc5572f48cc24883681db65530bd284", "tree": "24ab92ec9b0cdd9e6f4c0bf7a8a4c04635be03db", "parents": [ "82ef04fb4c82542b3eda81cca461f0594ce9cd0b" ], "author": { "name": "Tejun Heo", "email": "tj@kernel.org", "time": "Thu Jul 31 17:02:41 2008 +0900" }, "committer": { "name": "Jeff Garzik", "email": "jgarzik@redhat.com", "time": "Mon Sep 29 00:22:30 2008 -0400" }, "message": "libata: reimplement link iterator\n\nImplement __ata_port_next_link() and reimplement\n__ata_port_for_each_link() and ata_port_for_each_link() using it.\nThis removes relatively large inlined code and makes iteration easier\nto extend.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nSigned-off-by: Jeff Garzik \u003cjgarzik@redhat.com\u003e\n" }, { "commit": "82ef04fb4c82542b3eda81cca461f0594ce9cd0b", "tree": "e513df5ad8dc9f7400830bfc8786afb6bec90fb6", "parents": [ "6ef190cc92e33565accff6a320f0e7d90480bfe7" ], "author": { "name": "Tejun Heo", "email": "tj@kernel.org", "time": "Thu Jul 31 17:02:40 2008 +0900" }, "committer": { "name": "Jeff Garzik", "email": "jgarzik@redhat.com", "time": "Mon Sep 29 00:22:28 2008 -0400" }, "message": "libata: make SCR access ops per-link\n\nLogically, SCR access ops should take @link; however, there was no\ncompelling reason to convert all SCR access ops when adding @link\nabstraction as there\u0027s one-to-one mapping between a port and a non-PMP\nlink.
