We rely on get_{idle,iowait}_time functions to retrieve\nproper data.\n\nThese functions, however, use usecs_to_cputime to translate micro\nseconds time to cputime64_t. This is just an alias to usecs_to_jiffies\nwhich reduces the data type from u64 to unsigned int and also checks\nwhether the given parameter overflows jiffies_to_usecs(MAX_JIFFY_OFFSET)\nand returns MAX_JIFFY_OFFSET in that case.\n\nWhen we overflow depends on CONFIG_HZ but especially for CONFIG_HZ_300\nit is quite low (1431649781) so we are getting MAX_JIFFY_OFFSET for\n\u003e3000s! until we overflow unsigned int. Just for reference\nCONFIG_HZ_100 has an overflow window around 20s, CONFIG_HZ_250 ~8s and\nCONFIG_HZ_1000 ~2s.\n\nThis results in a bug when people saw [h]top going mad reporting 100%\nCPU usage even though there was basically no CPU load. The reason was\nsimply that /proc/stat stopped reporting idle/io_wait changes (and\nreported MAX_JIFFY_OFFSET) and so the only change happening was for user\nsystem time.\n\nLet\u0027s use nsecs_to_jiffies64 instead which doesn\u0027t reduce the precision\nto 32b type and it is much more appropriate for cumulative time values\n(unlike usecs_to_jiffies which intended for timeout calculations).\n\nSigned-off-by: Michal Hocko \u003cmhocko@suse.cz\u003e\nTested-by: Artem S.

making it appear as a more\nserious problem (the presence of a stack trace and being multiline should\nattract more attention) so that applications still using the old interface\ncan get fixed.\n\nVery popular users of the old interface have been converted since the oom\nkiller rewrite has been introduced. udevd switched to the\n/proc/pid/oom_score_adj interface for v162, kde switched in 4.6.1, and\nopensshd switched in 5.7p1.\n\nAt the start of 2012, this should be changed into a WARN() to emit all\nsuch incidents and then finally remove the tunable in August 2012

Arnd suggested\nlooking at sysfs for that, so this change moves that information\nto a pair of sysfs attributes (chip_width and chip_height) in the\n/sys/devices/system/cpu directory. We also put the \"chip_serial\"\nand \"chip_revision\" information from our old /proc/tile/board file\nas attributes in /sys/devices/system/cpu.\n\nOther information collected via hypervisor APIs is now placed in\n/sys/hypervisor. We create a /sys/hypervisor/type file (holding the\nconstant string \"tilera\") to be parallel with the Xen use of\n/sys/hypervisor/type holding \"xen\". We create three top-level files,\n\"version\" (the hypervisor\u0027s own version), \"config_version\" (the\nversion of the configuration file), and \"hvconfig\" (the contents of\nthe configuration file). The remaining information from our old\n/proc/tile/board and /proc/tile/switch files becomes an attribute\ngroup appearing under /sys/hypervisor/board/.\n\nFinally, after some feedback from Arnd Bergmann for the previous\nversion of this patch, the /proc/tile/hardwall file is split up into\ntwo conceptual parts. First, a directory /proc/tile/hardwall/ which\ncontains one file per active hardwall, each file named after the\nhardwall\u0027s ID and holding a cpulist that says which cpus are enclosed by\nthe hardwall. Second, a /proc/PID file \"hardwall\" that is either\nempty (for non-hardwall-using processes) or contains the hardwall ID.\n\nFinally, this change pushes the /proc/sys/tile/unaligned_fixup/\ndirectory, with knobs controlling the kernel code for handling the\nfixup of unaligned exceptions.\n\nReviewed-by: Arnd Bergmann \u003carnd@arndb.de\u003e\nSigned-off-by: Chris Metcalf \u003ccmetcalf@tilera.com\u003e\n" }, { "commit": "997c136f518c5debd63847e78e2a8694f56dcf90", "tree": "ac2ff48901be3e6834757675dcc177732e034a9f", "parents": [ "98bc93e505c03403479c6669c4ff97301cee6199" ], "author": { "name": "Olaf Hering", "email": "olaf@aepfle.de", "time": "Thu May 26 16:25:54 2011 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu May 26 17:12:37 2011 -0700" }, "message": "fs/proc/vmcore.c: add hook to read_from_oldmem() to check for non-ram pages\n\nThe balloon driver in a Xen guest frees guest pages and marks them as\nmmio.

Since the\nreads come in as 8byte requests each ballooned page is tried 512 times.\n\nWith this change a hook can be registered which checks wether the given\npfn is really ram. The hook has to return a value \u003e 0 for ram pages, a\nvalue \u003c 0 on error (because the hypercall is not known) and 0 for non-ram\npages.\n\nThis will reduce the time to read /proc/vmcore.
