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": "2486fa561a3192bbbec39c7feef87a1e07bd6342", "tree": "4241264273c63714e4c2021e7de69aee8bb2b20c", "parents": [ "bfce5e0179ad059035df28558724ff60af708e09" ], "author": { "name": "Tejun Heo", "email": "tj@kernel.org", "time": "Thu Jul 31 07:52:40 2008 +0900" }, "committer": { "name": "Jeff Garzik", "email": "jgarzik@redhat.com", "time": "Thu Jul 31 01:47:05 2008 -0400" }, "message": "libata: update atapi disable handling\n\nGlobal and per-LLD ATAPI disable checks were done in the command issue\npath probably because it was left out during EH conversion.

In an attempt to compensate libata\u0027s previous shortcoming,\nsome distros sync and spin down disks attached via libata in their\nshutdown(8). Some disks spin back up just to spin down again on\nSTANDBYNOW1 if the command is issued when the disk is spun down, so\nthis double spinning down causes problem.\n\nThis patch implements module parameter libata.spindown_compat which,\nwhen set to one (default value), prevents libata from spinning down\ndisks on shutdown thus avoiding double spinning down. Note that\nlibata spins down disks for suspend to mem and disk, so with\nlibata.spindown_compat set to one, disks should be properly spun down\nin all cases without modifying shutdown(8).\n\nshutdown(8) should be fixed eventually. Some drive do spin up on\nSYNCHRONZE_CACHE even when their cache is clean. Those disks\ncurrently spin up briefly when sd tries to shutdown the device and\nthen the machine powers off immediately, which can\u0027t be good for the\nhead. We can\u0027t skip SYNCHRONIZE_CACHE during shudown as it can be\ndangerous data integrity-wise.\n\nSo, this spindown_compat parameter is already scheduled for removal by\nthe end of the next year and here\u0027s what shutdown(8) should do.\n\n * Check whether /sys/modules/libata/parameters/spindown_compat\n exists. If it does, write 0 to it.\n\n * For each libata harddisk {\n\t* Check whether /sys/class/scsi_disk/h:c:i:l/manage_start_stop\n\t exists.
