Data\nis added to the buffers from in interrupt context. The data\nis periodically pushed to the kernel buffer via a new Oprofile\nfunction oprofile_put_buff(). The oprofile_put_buff() function\nis called via a work queue enabling the funtion to acquire the\nmutex lock.\n\nThe existing user controls for adjusting the per CPU buffer\nsize is used to control the size of the per SPU buffers.\nSimilarly, overflows of the SPU buffers are reported by\nincrementing the per CPU buffer stats. This eliminates the\nneed to have architecture specific controls for the per SPU\nbuffers which is not acceptable to the OProfile user tool\nmaintainer.\n\nThe export of the oprofile add_event_entry() is removed as it\nis no longer needed given this patch.\n\nNote, this patch has not addressed the issue of indexing arrays\nby the spu number. This still needs to be fixed as the spu\nnumbering is not guarenteed to be 0 to max_num_spus-1.\n\nSigned-off-by: Carl Love \u003ccarll@us.ibm.com\u003e\nSigned-off-by: Maynard Johnson \u003cmaynardj@us.ibm.com\u003e\nSigned-off-by: Arnd Bergmann \u003carnd@arndb.de\u003e\nAcked-by: Acked-by: Robert Richter \u003crobert.richter@amd.com\u003e\nSigned-off-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\n" }, { "commit": "9b1f261166f56d4b2c33fdf5aad64edd5e30b46f", "tree": "748011b45dc178a218df9146921ca027fa99b2cc", "parents": [ "4bd9b9dc97e344670e9e5762399a07dcd5f15311" ], "author": { "name": "Barry Kasindorf", "email": "barry.kasindorf@amd.com", "time": "Tue Jul 15 00:10:36 2008 +0200" }, "committer": { "name": "Robert Richter", "email": "robert.richter@amd.com", "time": "Mon Oct 20 13:44:21 2008 +0200" }, "message": "OProfile: Fix buffer synchronization for IBS\n\nThe patch is needed since there is some IBS code in add_ibs_begin()\nthat handles more than one sample per iteration.

For most filesystems, this should be done with simple_set_mnt()\nwhich will set the superblock pointer and then set the root dentry to the\nsuperblock\u0027s s_root (as per the old default behaviour).\n\nThe get_sb() op now returns an integer as there\u0027s now no need to return the\nsuperblock pointer.\n\nThis patch permits a superblock to be implicitly shared amongst several mount\npoints, such as can be done with NFS to avoid potential inode aliasing. In\nsuch a case, simple_set_mnt() would not be called, and instead the mnt_root\nand mnt_sb would be set directly.\n\nThe patch also makes the following changes:\n\n (*) the get_sb_*() convenience functions in the core kernel now take a vfsmount\n pointer argument and return an integer, so most filesystems have to change\n very little.\n\n (*) If one of the convenience function is not used, then get_sb() should\n normally call simple_set_mnt() to instantiate the vfsmount. This will\n always return 0, and so can be tail-called from get_sb().\n\n (*) generic_shutdown_super() now calls shrink_dcache_sb() to clean up the\n dcache upon superblock destruction rather than shrink_dcache_anon().\n\n This is required because the superblock may now have multiple trees that\n aren\u0027t actually bound to s_root, but that still need to be cleaned up. The\n currently called functions assume that the whole tree is rooted at s_root,\n and that anonymous dentries are not the roots of trees which results in\n dentries being left unculled.\n\n However, with the way NFS superblock sharing are currently set to be\n implemented, these assumptions are violated: the root of the filesystem is\n simply a dummy dentry and inode (the real inode for \u0027/\u0027 may well be\n inaccessible), and all the vfsmounts are rooted on anonymous[*] dentries\n with child trees.\n\n [*] Anonymous until discovered from another tree.\n\n (*) The documentation has been adjusted, including the additional bit of\n changing ext2_* into foo_* in the documentation.\n\n[akpm@osdl.org: convert ipath_fs, do other stuff]\nSigned-off-by: David Howells \u003cdhowells@redhat.com\u003e\nAcked-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\nCc: Nathan Scott \u003cnathans@sgi.com\u003e\nCc: Roland Dreier \u003crolandd@cisco.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "99ac48f54a91d02140c497edc31dc57d4bc5c85d", "tree": "68719391694a6914191bdf73d2071875f7653f6f", "parents": [ "ec1b9466cb4f6ae6d950bd67055d9410d1056d2a" ], "author": { "name": "Arjan van de Ven", "email": "arjan@infradead.org", "time": "Tue Mar 28 01:56:41 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Tue Mar 28 09:16:05 2006 -0800" }, "message": "[PATCH] mark f_ops const in the inode\n\nMark the f_ops members of inodes as const, as well as fix the\nripple-through this causes by places that copy this f_ops and then \"do\nstuff\" with it.\n\nSigned-off-by: Arjan van de Ven \u003carjan@infradead.org\u003e\nSigned-off-by: Alexey Dobriyan \u003cadobriyan@gmail.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "fe449f48368623eb47715061b4977ce982d8e03b", "tree": "46536755b6b56d4e990f651c08e7ac01fa14d4af", "parents": [ "0fed48463fb20c6bcabc5cf70e2de47b30507ee1" ], "author": { "name": "KAMEZAWA Hiroyuki", "email": "kamezawa.hiroyu@jp.fujitsu.com", "time": "Tue Mar 28 01:56:38 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Tue Mar 28 09:16:05 2006 -0800" }, "message": "[PATCH] for_each_possible_cpu: oprofile.\n\nThis patch replaces for_each_cpu with for_each_possible_cpu.\n\nSigned-off-by: KAMEZAWA Hiroyuki \u003ckamezawa.hiroyu@jp.fujitsu.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "273577165cd206d2d6689ee4b18aa13de1ec4bde", "tree": "f5dfaed2e193bb65a00ef551f02ace8726cc461c", "parents": [ "f83ca9fe3ee390755f18b4a7780c25ce593b484a" ], "author": { "name": "Brian Rogan", "email": "bcr6@cornell.edu", "time": "Tue Mar 28 01:56:20 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Tue Mar 28 09:16:02 2006 -0800" }, "message": "[PATCH] Add oprofile_add_ext_sample\n\nOn ppc64 we look at a profiling register to work out the sample address and\nif it was in userspace or kernel.\n\nThe backtrace interface oprofile_add_sample does not allow this.
