And at\nthis point it really does become very natural to start to peel off some of\nthe error labels and move them into the helper functions - now the\n\"truncated\" case is gone, and is handled inside that setup function\ninstead.\n\nSo maybe you don\u0027t like this approach, and it does make the variable\naccesses a bit longer, but I don\u0027t think unreadably so. And the patch\nreally does look big and scary, but there really should be absolutely no\nsemantic changes - most of it was a trivial and mindless rename.\n\nIn fact, it was so mindless that I on purpose kept the existing helper\nfunctions looking like this:\n\n- err \u003d check_modinfo(mod, sechdrs, infoindex, versindex);\n+ err \u003d check_modinfo(mod, info.sechdrs, info.index.info, info.index.vers);\n\nrather than changing them to just take the \"info\" pointer. IOW, a second\nphase (if you think the approach is ok) would change that calling\nconvention to just do\n\n\terr \u003d check_modinfo(mod, \u0026info);\n\n(and same for \"layout_sections()\", \"layout_symtabs()\" etc.) Similarly,\nwhile right now it makes things _look_ bigger, with things like this:\n\n\tversindex \u003d find_sec(hdr, sechdrs, secstrings, \"__versions\");\n\nbecoming\n\n\tinfo-\u003eindex.vers \u003d find_sec(info-\u003ehdr, info-\u003esechdrs, info-\u003esecstrings, \"__versions\");\n\nin the new \"setup_module_info()\" function, that\u0027s again just a result of\nit being a search-and-replace patch. By using the \u0027info\u0027 pointer, we could\njust change the \u0027find_sec()\u0027 interface so that it ends up being\n\n\tinfo-\u003eindex.vers \u003d find_sec(info, \"__versions\");\n\ninstead, and then we\u0027d actually have a shorter and more readable line.

Most callers of udelay are in device/\ndriver initialization code, which is serial...\n\n\tAs I see it, there is only benefit to sleeping over a delay; the\n\tnotion of \"refactoring\" areas that use udelay was presented, but\n\tI see usleep as the refactoring. Consider i2c, if the bus is busy,\n\tyou need to wait a bit (say 100us) before trying again, your\n\tcurrent options are:\n\n\t\t* udelay(100)\n\t\t* msleep(1) \u003c-- As noted above, actually as high as ~20ms\n\t\t\t\ton some platforms, so not really an option\n\t\t* Manually set up an hrtimer to try again in 100us (which\n\t\t is what usleep does anyway...)\n\n\tPeople choose the udelay route because it is EASY; we need to\n\tprovide a better easy route.\n\n\tDevice / driver / boot code is *currently* serial, but every few\n\tmonths someone makes noise about parallelizing boot, and IMHO, a\n\tlittle forward-thinking now is one less thing to worry about\n\tif/when that ever happens\n\nudelay\u0027s could be preempted\n\n\tSure, but if udelay plans on looping 1000 times, and it gets\n\tpreempted on loop 200, whenever it\u0027s scheduled again, it is\n\tgoing to do the next 800 loops.\n\nIs the interruptible case needed?\n\n\tProbably not, but I see usleep as a very logical parallel to msleep,\n\tso it made sense to include the \"full\" API. Processors are getting\n\tfaster (albeit not as quickly as they are becoming more parallel),\n\tso if someone wanted to be interruptible for a few usecs, why not\n\tlet them? If this is a contentious point, I\u0027m happy to remove it.\n\nOTHER THOUGHTS\n\nI believe there is also value in exposing the usleep_range option; it gives\nthe scheduler a lot more flexibility and allows the programmer to express\nhis intent much more clearly; it\u0027s something I would hope future driver\nwriters will take advantage of.\n\nTo get the results in the NUMBERS section below, I literally s/udelay/usleep\nthe kernel tree; I had to go in and undo the changes to the USB drivers, but\neverything else booted successfully; I find that extremely telling in and\nof itself -- many people are using a delay API where a sleep will suit them\njust fine.\n\nSOME ATTEMPTS AT NUMBERS\n\nIt turns out that calculating quantifiable benefit on this is challenging,\nso instead I will simply present the current state of things, and I hope\nthis to be sufficient:\n\nHow many udelay calls are there in 2.6.35-rc5?\n\n\tudealy(ARG) \u003e\u003d\t| COUNT\n\t1000\t\t| 319\n\t500\t\t| 414\n\t100\t\t| 1146\n\t20\t\t| 1832\n\nI am working on Android, so that is my focus for this. The following table\nis a modified usleep that simply printk\u0027s the amount of time requested to\nsleep; these tests were run on a kernel with udelay \u003e\u003d 20 --\u003e usleep\n\n\"boot\" is power-on to lock screen\n\"power collapse\" is when the power button is pushed and the device suspends\n\"resume\" is when the power button is pushed and the lock screen is displayed\n (no touchscreen events or anything, just turning on the display)\n\"use device\" is from the unlock swipe to clicking around a bit; there is no\n\tsd card in this phone, so fail loading music, video, camera\n\n\tACTION\t\t| TOTAL NUMBER OF USLEEP CALLS\t| NET TIME (us)\n\tboot\t\t| 22\t\t\t\t| 1250\n\tpower-collapse\t| 9\t\t\t\t| 1200\n\tresume\t\t| 5\t\t\t\t| 500\n\tuse device\t| 59\t\t\t\t| 7700\n\nThe most interesting category to me is the \"use device\" field; 7700us of\nbusy-wait time that could be put towards better responsiveness, or at the\nleast less power usage.\n\nSigned-off-by: Patrick Pannuto \u003cppannuto@codeaurora.org\u003e\nCc: apw@canonical.com\nCc: corbet@lwn.net\nCc: arjan@linux.intel.com\nCc: Randy Dunlap \u003crdunlap@xenotime.net\u003e\nCc: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\n" }, { "commit": "e1b004c3ef9c59db5f013528628b51c8653155ec", "tree": "2c60763d361df84131852c3351c7fc0cd754614d", "parents": [ "af5ab277ded04bd9bc6b048c5a2f0e7d70ef0867" ], "author": { "name": "Thomas Gleixner", "email": "tglx@linutronix.de", "time": "Wed Aug 04 10:53:00 2010 +0200" }, "committer": { "name": "Thomas Gleixner", "email": "tglx@linutronix.de", "time": "Wed Aug 04 10:53:00 2010 +0200" }, "message": "Revert \"timer: Added usleep[_range] timer\"\n\nThis reverts commit 22b8f15c2f7130bb0386f548428df2ffd4e81903 to merge\nan advanced version.\n\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\n" }, { "commit": "412a4ac5e9cf7fdeb6af562c25547a9b9da7674f", "tree": "a8ce13cbc9c47c99799e5e3e3ad26ba78274ee73", "parents": [ "e8e5c2155b0035b6e04f29be67f6444bc914005b", "0c2daaafcdec726e89cbccca61d576de8429c537" ], "author": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Wed Aug 04 10:26:03 2010 +1000" }, "committer": { "name": "Benjamin Herrenschmidt", "email": "benh@kernel.crashing.org", "time": "Wed Aug 04 10:26:03 2010 +1000" }, "message": "Merge commit \u0027gcl/next\u0027 into next\n" }, { "commit": "8cadd2831bf3abc94f4530e7fdbab7bb39b6b27d", "tree": "4027798914cc3213692a4865797898a5ae0a0b49", "parents": [ "81f61484f16decba0fb68400fe0036b337b4cdc7" ], "author": { "name": "Jesse Barnes", "email": "jbarnes@virtuousgeek.org", "time": "Mon May 10 14:26:20 2010 -0700" }, "committer": { "name": "Matthew Garrett", "email": "mjg@redhat.com", "time": "Tue Aug 03 09:48:45 2010 -0400" }, "message": "timer: add on-stack deferrable timer interfaces\n\nIn some cases (for instance with kernel threads) it may be desireable to\nuse on-stack deferrable timers to get their power saving benefits.

The\nassumption was that a cpu number should be below PAGE_OFFSET while a\npointer to cwq should be above it. However, on architectures which\nuse separate address spaces for user and kernel spaces, this doesn\u0027t\nhold as PAGE_OFFSET is zero.\n\nFix it by using an explicit flag, WORK_STRUCT_CWQ, to mark what the\ndata field contains.
