Extract eventfilter declarations to sys/_eventfilter.h

2019-05-20T00:38:23Z

This allows replacing "sys/eventfilter.h" includes with "sys/_eventfilter.h" in other header files (e.g., sys/{bus,conf,cpu}.h) and reduces header pollution substantially. EVENTHANDLER_DECLARE and EVENTHANDLER_LIST_DECLAREs were moved out of .c files into appropriate headers (e.g., sys/proc.h, powernv/opal.h). As a side effect of reduced header pollution, many .c files and headers no longer contain needed definitions. The remainder of the patch addresses adding appropriate includes to fix those files. LOCK_DEBUG and LOCK_FILE_LINE_ARG are moved to sys/_lock.h, as required by sys/mutex.h since r326106 (but silently protected by header pollution prior to this change). No functional change (intended). Of course, any out of tree modules that relied on header pollution for sys/eventhandler.h, sys/lock.h, or sys/mutex.h inclusion need to be fixed. __FreeBSD_version has been bumped.

[led] propagate error from set_led() to the caller

Do not lose error condition by always returning 0 from set_led. None of the calls to set_led checks for return value at the moment so none of API consumers in base is affected. PR: 231567 Submitted by: Bertrand Petit MFC after: 1 week

https://www.kernel.org/doc/Documentation/devicetree/bindings/leds/leds-gpio.txt Without this booting the VSATV102 causes the blue "working" led to turn off when the kernel starts up. With this the led (which is turned on by the firmware) stays on since that's the default state specified in the FDT. Expanded the meaning of the led_create_state state parameter in order to implement support for "keep". The original values were: == 0 Off != 0 On The new values are: == -1 don't change / keep current setting == 0 Off != -1 && != 0 On This should have no effect on acpi_asus_attach which only calls led_create_state with state set to 1. Updated acpi_ibm_attach in order to avoid surprises. Differential Revision: https://reviews.freebsd.org/D2615 Submitted by: John Wehle Reviewed by: gonzo, loos

Make led(4) fire callouts at 10Hz only when there is at least one LED that is requested to blink. Do not fire if all LEDs are static (usual case).

Remove unit2minor() use from kernel code.

2008-09-26T14:19:52Z

When I changed kern_conf.c three months ago I made device unit numbers equal to (unneeded) device minor numbers. We used to require bitshifting, because there were eight bits in the middle that were reserved for a device major number. Not very long after I turned dev2unit(), minor(), unit2minor() and minor2unit() into macro's. The unit2minor() and minor2unit() macro's were no-ops. We'd better not remove these four macro's from the kernel, because there is a lot of (external) code that may still depend on them. For now it's harmless to remove all invocations of unit2minor() and minor2unit(). Reviewed by: kib
