original implementation from Jiangbi Liu and Maciej Trela.\n\nATAPI transfers happen in two-to-three stages. 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.

Prepare for\nthis change by updating users of gfp and slab facilities include those\nheaders directly instead of assuming availability. As this conversion\nneeds to touch large number of source files, the following script is\nused as the basis of conversion.\n\n http://userweb.kernel.org/~tj/misc/slabh-sweep.py\n\nThe script does the followings.\n\n* Scan files for gfp and slab usages and update includes such that\n only the necessary includes are there. ie. if only gfp is used,\n gfp.h, if slab is used, slab.h.\n\n* When the script inserts a new include, it looks at the include\n blocks and try to put the new include such that its order conforms\n to its surrounding. It\u0027s put in the include block which contains\n core kernel includes, in the same order that the rest are ordered -\n alphabetical, Christmas tree, rev-Xmas-tree or at the end if there\n doesn\u0027t seem to be any matching order.\n\n* If the script can\u0027t find a place to put a new include (mostly\n because the file doesn\u0027t have fitting include block), it prints out\n an error message indicating which .h file needs to be added to the\n file.\n\nThe conversion was done in the following steps.\n\n1. The initial automatic conversion of all .c files updated slightly\n over 4000 files, deleting around 700 includes and adding ~480 gfp.h\n and ~3000 slab.h inclusions. The script emitted errors for ~400\n files.\n\n2. Each error was manually checked. Some didn\u0027t need the inclusion,\n some needed manual addition while adding it to implementation .h or\n embedding .c file was more appropriate for others. This step added\n inclusions to around 150 files.\n\n3. The script was run again and the output was compared to the edits\n from #2 to make sure no file was left behind.\n\n4. Several build tests were done and a couple of problems were fixed.\n e.g. lib/decompress_*.c used malloc/free() wrappers around slab\n APIs requiring slab.h to be added manually.\n\n5. The script was run on all .h files but without automatically\n editing them as sprinkling gfp.h and slab.h inclusions around .h\n files could easily lead to inclusion dependency hell. Most gfp.h\n inclusion directives were ignored as stuff from gfp.h was usually\n wildly available and often used in preprocessor macros. Each\n slab.h inclusion directive was examined and added manually as\n necessary.\n\n6. percpu.h was updated not to include slab.h.\n\n7. Build test were done on the following configurations and failures\n were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my\n distributed build env didn\u0027t work with gcov compiles) and a few\n more options had to be turned off depending on archs to make things\n build (like ipr on powerpc/64 which failed due to missing writeq).\n\n * x86 and x86_64 UP and SMP allmodconfig and a custom test config.\n * powerpc and powerpc64 SMP allmodconfig\n * sparc and sparc64 SMP allmodconfig\n * ia64 SMP allmodconfig\n * s390 SMP allmodconfig\n * alpha SMP allmodconfig\n * um on x86_64 SMP allmodconfig\n\n8. percpu.h modifications were reverted so that it could be applied as\n a separate patch and serve as bisection point.\n\nGiven the fact that I had only a couple of failures from tests on step\n6, I\u0027m fairly confident about the coverage of this conversion patch.\nIf there is a breakage, it\u0027s likely to be something in one of the arch\nheaders which should be easily discoverable easily on most builds of\nthe specific arch.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nGuess-its-ok-by: Christoph Lameter \u003ccl@linux-foundation.org\u003e\nCc: Ingo Molnar \u003cmingo@redhat.com\u003e\nCc: Lee Schermerhorn \u003cLee.Schermerhorn@hp.com\u003e\n" }, { "commit": "e881a172dac4d9ea3b2a1540041d872963c269bd", "tree": "9eb1f344b107806c0041c4e0a64192a055117289", "parents": [ "dbf9bfe615717d1145f263c0049fe2328e6ed395" ], "author": { "name": "Mike Christie", "email": "michaelc@cs.wisc.edu", "time": "Thu Oct 15 17:46:39 2009 -0700" }, "committer": { "name": "James Bottomley", "email": "James.Bottomley@suse.de", "time": "Fri Dec 04 12:00:41 2009 -0600" }, "message": "[SCSI] modify change_queue_depth to take in reason why it is being called\n\nThis patch modifies scsi_host_template-\u003echange_queue_depth so that\nit takes an argument indicating why it is being called.
