* hwclock: add --delay <seconds>Karel Zak2018-07-181-0/+2
| | | | | | | | | | | * add command line option --delay <seconds> * read RTC type from /sys/class/rtc/rtc<N>/name * default to 0.5 (500ms) for rtc_cmos or when RTC type is impossible determine; otherwise delay is 0. Signed-off-by: Karel Zak <kzak@redhat.com>
* hwclock: add --ul-debug implementing debug.hJ William Piggott2018-01-221-2/+12
| | | | | | | | | | | | | | | | | Undocumented at this time, because it is a skeleton implementation. More debugging points are to be added after refactoring is complete, or ad hoc in the mean time. When fully implemented, enough time may have passed that the deprecated --debug could be used to replace --ul-debug.

* hwclock: remove bool type definitionSami Kerola2017-08-301-2/+0Star
| | | | | | | | | Use plain int instead of type defining it to a boolean, and use numbers to signify true or false as we do everywhere else in this source tree. And in hwclock-cmos.c file booleans weren't even needed, to the related code is removed. Signed-off-by: Sami Kerola <kerolasa@iki.fi>
* hwclock: remove busywait tristate return statusJ William Piggott2017-08-041-6/+0Star
| | | | | | | | | The select() synchronization branch only returns success or fail. There is no reason for the busywait branch to do more. If synchronization fails for any reason then it must exit, otherwise all drift correction operation will be invalid. Signed-off-by: J William Piggott <elseifthen@gmx.com>
* hwclock: remove custom errno stringJ William Piggott2017-07-311-1/+0Star
| | | | | | | | | | | | | | | | | | | | | | Custom errno messages are unnecessary and problematic for translators. hwclock --directisa hwclock: iopl() port access failed: Operation not permitted hwclock: root privileges may be required The custom errno message is misleading. We do not know what the system permissions are set to. The default errno string is correct, and enough.

* hwclock: --epoch presence test failsJ William Piggott2017-07-161-1/+1
| | | | | | | | | | | | | | hwclock --setepoch --epoch 0 Will warn that the epoch option is required. The --epoch presence test is made on its argument after it is converted to an integer. This means any value it can be tested for, can also be given as an input. So make the conversion after the presence test, like the --date option does.

* hwclock: improve audit controlJ William Piggott2017-04-191-2/+0Star
| | | | | | | | | | | Move audit control to option parsing. This fixes non-alpha build error and cleans up an unruly 'if' statement. Having audit control in option parsing may also draw awareness to the audit system when adding new functions, which could easily be overlooked otherwise.

* hwclock: make epoch functions alpha onlyJ William Piggott2017-04-191-2/+6
| | | | | | | | | | | | | | | | | | | | | | It's been 19.1315 years since the comment below was written and the kernel has actually gone further away from allowing an RTC epoch on ISA machines. /* * Maintenance note: This should work on non-Alpha machines, but the * evidence today (98.03.04) indicates that the kernel only keeps the epoch * value on Alphas. If that is ever fixed, this function should be changed. */ The current behavior is to accept the epoch options on ISA machines only to print a lengthy message explaining that you cannot use them. This patch removes that behavior, making the epoch functions truly Alpha only, as the man-page states that they are. * sys-utils/hwclock.c: make epoch function alpha only. * sys-utils/hwclock.h: same.

* hwclock: remove unused 'silent' argJ William Piggott2017-03-311-1/+1
| | | | | | | | | | | | | | The 'silent' argument for get_epoch_rtc() was used to silence error messages when querying the rtc driver for an alpha epoch while using cmos direct access.

* hwclock: remove --compare optionSami Kerola2017-02-051-1/+0Star
| | | | | | | | | | | Compare functionality was printing nonsense values. There is no knowledge of anyone using this broken functionality. Instead of deprecating the code for months, and removing it after few release, it is removed immediately. Needless to say this is unusual removal.

* hwclock: move command-line options to control structureSami Kerola2017-02-051-10/+50
| | | | | | | | | | | | | | | The control structure is read-only everywhere else but in main(). Almost all changes are about how variables are referred, with one exception. Calls to read_adjtime() from manipulate_clock() and compare_clock() are moved to main(). This way it is possible to keep variable that tells if hwclock is using UTC-0 be part of control structure. Changes within #ifdef __alpha__ segments were tested by flipping the preprocessor directivive otherway around and getting good compilaton all the way to the point where linking on none-alpha system failed.
