Each implemented feature will have one of such section\nheader that provides the offset and the size of the data\nmanipulated by the feature.\n\nThe trace informations have moved after the data and are\nrecorded on exit time.\n\nThe new layout is as follows:\n\n -----------------------\n ___\n [ magic ] |\n [ header size ] |\n [ attr size ] |\n [ attr content offset ] |\n [ attr content size ] |\n [ data offset ] File Headers\n [ data size ] |\n [ event_types offset ] |\n [ event_types size ] |\n [ feature bitmap ] v\n\n [ attr section ]\n [ events section ]\n\n ___\n [ X ] |\n [ X ] |\n [ X ] Datas\n [ X ] |\n [ X ] v\n\n ___\n [ Feature 1 offset ] |\n [ Feature 1 size ] Features headers\n [ Feature 2 offset ] |\n [ Feature 2 size ] v\n\n [ Feature 1 content ]\n [ Feature 2 content ]\n -----------------------\n\nWe have as many feature\u0027s section headers as we have features in\nuse for the current file.\n\nSay Feat 1 and Feat 3 are used by the file, but not Feat 2. Then\nthe feature headers will be like follows:\n\n[ Feature 1 offset ] |\n[ Feature 1 size ] Features headers\n[ Feature 3 offset ] |\n[ Feature 3 size ] v\n\nThere is no hole to cover Feature 2 that is not in use here. We\nonly need to cover the needed headers in order, from the lowest\nfeature bit to the highest.\n\nCurrently we have two features: HEADER_TRACE_INFO and\nHEADER_BUILD_ID. Both have their contents that follow the\nfeature headers. Putting the contents right after the feature\nheaders is not mandatory though. While we keep the feature\nheaders right after the data and in order, their offsets can\npoint everywhere. We have just put the two above feature\ncontents in the end of the file for convenience.\n\nThe purpose of this layout change is to have a file format that\nscales while keeping it simple: having such linear feature\nheaders is less error prone wrt forward/backward compatibility\nas the content of a feature can be put anywhere, its location\ncan even change by the time, it\u0027s fine because its headers will\ntell where it is. And we know how to find these headers,\nfollowing the above rules.\n\nSigned-off-by: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nCc: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\nCc: Mike Galbraith \u003cefault@gmx.de\u003e\nCc: Paul Mackerras \u003cpaulus@samba.org\u003e\nCc: Hitoshi Mitake \u003cmitake@dcl.info.waseda.ac.jp\u003e\nLKML-Reference: \u003c1257911467-28276-6-git-send-email-fweisbec@gmail.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "3e13ab2d83b6867a20663c73c184f29c2fde1558", "tree": "d0c67b84db78934e5a8c634261d0df017f0038fb", "parents": [ "4778d2e4f410c6eea32f594cb2be9590bcb28b84" ], "author": { "name": "Frederic Weisbecker", "email": "fweisbec@gmail.com", "time": "Wed Nov 11 04:51:06 2009 +0100" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Wed Nov 11 07:30:19 2009 +0100" }, "message": "perf tools: Use perf_header__set/has_feat whenever possible\n\nAnd drop the alternate checks/sets using set_bit or other kind\nof helpers.\n\nSigned-off-by: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nCc: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\nCc: Mike Galbraith \u003cefault@gmx.de\u003e\nCc: Paul Mackerras \u003cpaulus@samba.org\u003e\nCc: Hitoshi Mitake \u003cmitake@dcl.info.waseda.ac.jp\u003e\nLKML-Reference: \u003c1257911467-28276-5-git-send-email-fweisbec@gmail.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "4778d2e4f410c6eea32f594cb2be9590bcb28b84", "tree": "99625c6a532d83606e0d6c8ec7c812d5d5047e50", "parents": [ "57f395a7eabb913d3605d7392be5bdb0837c9f3d" ], "author": { "name": "Frederic Weisbecker", "email": "fweisbec@gmail.com", "time": "Wed Nov 11 04:51:05 2009 +0100" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Wed Nov 11 07:30:18 2009 +0100" }, "message": "perf tools: Read the build-ids from the header layer\n\nKeep the build-ids reading implementation in the data mapping\nbut move its call to the headers so that we have a better\ncontrol on it (offset seeking, size passing, etc..).\n\nSigned-off-by: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nCc: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\nCc: Mike Galbraith \u003cefault@gmx.de\u003e\nCc: Paul Mackerras \u003cpaulus@samba.org\u003e\nCc: Hitoshi Mitake \u003cmitake@dcl.info.waseda.ac.jp\u003e\nLKML-Reference: \u003c1257911467-28276-4-git-send-email-fweisbec@gmail.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "57f395a7eabb913d3605d7392be5bdb0837c9f3d", "tree": "141135524cbdb9fa27b48f361443a91b10726f7d", "parents": [ "8671dab9d5b2f0b444b8d09792384dccbfd43d14" ], "author": { "name": "Frederic Weisbecker", "email": "fweisbec@gmail.com", "time": "Wed Nov 11 04:51:04 2009 +0100" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Wed Nov 11 07:30:18 2009 +0100" }, "message": "perf tools: Split up build id saving into fetch and write\n\nWe are saving the build id once we stop the profiling.
