2019-05-20Extract eventfilter declarations to sys/_eventfilter.hConrad Meyer
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.

2015-05-24This implements default-state support as described in:Ganbold Tsagaankhuu
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 Notes: svn path=/head/; revision=283360

2008-09-26Remove unit2minor() use from kernel code.Ed Schouten
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 Notes: svn path=/head/; revision=183381

2008-05-29Remove the distinction between device minor and unit numbers.Ed Schouten
Even though we got rid of device major numbers some time ago, device drivers still need to provide unique device minor numbers to make_dev(). These numbers are only used inside the kernel. They are not related to device major and minor numbers which are visible in devfs. These are actually based on the inode number of the device. It would eventually be nice to remove minor numbers entirely, but we don't want to be too agressive here. Because the 8-15 bits of the device number field (si_drv0) are still reserved for the major number, there is no 1:1 mapping of the device minor and unit numbers. Because this is now unused, remove the restrictions on these numbers. The MAXMAJOR definition was actually used for two purposes. It was used to convert both the userspace and kernelspace device numbers to their major/minor pair, which is why it is now named UMINORMASK. minor2unit() and unit2minor() have now become useless. Both minor() and dev2unit() now serve the same purpose. We should eventually remove some of them, at least turning them into macro's. If devfs would become completely minor number unaware, we could consider using si_drv0 directly, just like si_drv1 and si_drv2. Approved by: philip (mentor) Notes: svn path=/head/; revision=179413
