users\n\nAn new optimization is making its way to ftrace. Its purpose is to\nmake trace_printk() consuming less memory and be faster.\n\nWritten by Lai Jiangshan, the approach is to delay the formatting\njob from tracing time to output time.\n\nCurrently, a call to trace_printk() will format the whole string and\ninsert it into the ring buffer. Then you can read it on /debug/tracing/trace\nfile.\n\nThe new implementation stores the address of the format string and\nthe binary parameters into the ring buffer, making the packet more compact\nand faster to insert.\nLater, when the user exports the traces, the format string is retrieved\nwith the binary parameters and the formatting job is eventually done.\n\nThe new implementation rewrites a lot of format decoding bits from\nvsnprintf() function, making now 3 differents functions to maintain\nin their duplicated parts of printf format decoding bits.\n\nSuggested by Ingo Molnar, this patch tries to factorize the most\npossible common bits from these functions.\nThe real common part between them is the format decoding. Although\nthey do somewhat similar jobs, their way to export or import the parameters\nis very different. Thus, only the decoding layer is extracted, unless you see\nother parts that could be worth factorized.\n\nChanges in V2:\n\n- Address a suggestion from Linus to group the format_decode() parameters inside\n a structure.\n\nChanges in v3:\n\n- Address other cleanups suggested by Ingo and Linus such as passing the\n printf_spec struct to the format helpers: pointer()/number()/string()\n Note that this struct is passed by copy and not by address. This is to\n avoid side effects because these functions often change these values and the\n changes shoudn\u0027t be persistant when a callee helper returns.\n It would be too risky.\n\n- Various cleanups (code alignement, switch/case instead of if/else fountains).\n\n- Fix a bug that printed the first format specifier following a %p\n\nChanges in v4:\n\n- drop unapropriate const qualifier loss while casting fmt to a char *\n (thanks to Vegard Nossum for having pointed this out).\n\nSigned-off-by: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\nAcked-by: Steven Rostedt \u003crostedt@goodmis.org\u003e\nLKML-Reference: \u003c1236356510-8381-6-git-send-email-fweisbec@gmail.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "4370aa4aa75391a5e2e06bccb0919109f725ed8e", "tree": "602a6ea4e404d17e610d4a9979d615ff2d0bfd98", "parents": [ "f036be96dd9ce442ffb9ab33e3c165f5178815c0" ], "author": { "name": "Lai Jiangshan", "email": "laijs@cn.fujitsu.com", "time": "Fri Mar 06 17:21:46 2009 +0100" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Fri Mar 06 17:39:04 2009 +0100" }, "message": "vsprintf: add binary printf\n\nImpact: add new APIs for binary trace printk infrastructure\n\nvbin_printf(): write args to binary buffer, string is copied\nwhen \"%s\" is occurred.\n\nbstr_printf(): read from binary buffer for args and format a string\n\n[fweisbec@gmail.com: rebase]\n\nSigned-off-by: Lai Jiangshan \u003claijs@cn.fujitsu.com\u003e\nSigned-off-by: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\nLKML-Reference: \u003c1236356510-8381-2-git-send-email-fweisbec@gmail.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "e899aa823ad74860a17b541b0ad38f513728923d", "tree": "019c4a1b7baafe9967aa50cc49e809c11d39f944", "parents": [ "ff083c8372f6312bb3a8c7f7b748920aeeb210c9" ], "author": { "name": "Pavel Machek", "email": "pavel@suse.cz", "time": "Tue Jan 06 14:40:53 2009 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Jan 06 15:59:12 2009 -0800" }, "message": "strict_strto* is not strict enough\n\nIt decodes \"\\n\" as 0, which is bad, because stray echo into backlight\nwill turn your backlight off, etc...\n\nSigned-off-by: Pavel Machek \u003cpavel@suse.cz\u003e\nCc: Yi Yang \u003cyi.y.yang@intel.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "d97106ab53f812910a62d18afb9dbe882819c1ba", "tree": "edd1a2c287b7d98ee7b62e7ea6457c8a10abe016", "parents": [ "3bfacef412b4bc993a8992217e50f1245f2fd3a6" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Jan 03 11:46:17 2009 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Jan 03 11:46:17 2009 -0800" }, "message": "Make %p print \u0027(null)\u0027 for NULL pointers\n\nBefore, when we only ever printed out the pointer value itself, a NULL\npointer would never cause issues and might as well be printed out as\njust its numeric value.\n\nHowever, with the extended %p formats, especially %pR, we might validly\nwant to print out resources for debugging.
