As computers have gotten faster and can now\nsplit microseconds easily, a new kernel interface using nanosecond units was\ndefined (\"the nanokernel\", confusing as that name is to OS hackers), and\nthere\u0027s an STA_NANO bit in the adjtimex() status field to tell the application\nwhich units it\u0027s using.\n\nThe current ntpd supports both, but Linux loses some possible timing\nresolution because of quantization effects, and the ntpd hackers would really\nlike to be able to drop the backwards compatibility code.\n\nUlrich Windl has been maintaining a patch set to do the conversion for years,\nbut it\u0027s hard to keep in sync.\n\nSigned-off-by: Roman Zippel \u003czippel@linux-m68k.org\u003e\nCc: john stultz \u003cjohnstul@us.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "04b617e71e363e640e88be1e43f53fa6a3afef9f", "tree": "b59e8e75e4671bc5e10f4fcaace85d4658d4d0f0", "parents": [ "97eebe138caaf78354b1fad233e63bafdcc4fd54" ], "author": { "name": "Roman Zippel", "email": "zippel@linux-m68k.org", "time": "Sat Sep 30 23:28:27 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Sun Oct 01 00:39:27 2006 -0700" }, "message": "[PATCH] ntp: convert time_freq to nsec value\n\nThis converts time_freq to a scaled nsec value and adds around 6bit of extra\nresolution.
