*	epoch_test: Assign different priorities using offset 1	Olivier Certner	2025-06-18	1	-1/+1
\| \| \| \| \| \| \| \| \|	Replace the hardcoded 4 (old RQ_PPQ) by 1 (new RQ_PPQ), as all priority levels are now treated differently. MFC after: 1 month Event: Kitchener-Waterloo Hackathon 202506 Sponsored by: The FreeBSD Foundation
*	sys: Automated cleanup of cdefs and other formatting	Warner Losh	2023-11-27	1	-1/+0
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Apply the following automated changes to try to eliminate no-longer-needed sys/cdefs.h includes as well as now-empty blank lines in a row. Remove /^#if.\n#endif.\n#include\s+<sys/cdefs.h>.\n/ Remove /\n+#include\s+<sys/cdefs.h>.\n+#if.\n#endif.\n+/ Remove /\n+#if.\n#endif.\n+/ Remove /^#if.\n#endif.\n/ Remove /\n+#include\s+<sys/cdefs.h>\n#include\s+<sys/types.h>/ Remove /\n+#include\s+<sys/cdefs.h>\n#include\s+<sys/param.h>/ Remove /\n+#include\s+<sys/cdefs.h>\n#include\s+<sys/capsicum.h>/ Sponsored by: Netflix
*	sys: Remove $FreeBSD$: one-line .c pattern	Warner Losh	2023-08-16	1	-2/+0
\| \| \| \|	Remove /^[\s]__FBSDID$"\$FreeBSD\$"$;?\s*\n/
*	Fix build of epoch_test module.	Hans Petter Selasky	2020-09-02	1	-1/+2
\| \| \| \| \| \| \| \| \| \|	While at it add missing epoch_free() call. MFC after: 1 week Sponsored by: Mellanox Technologies // NVIDIA Networking Notes: svn path=/head/; revision=365235
*	Mark more nodes as CTLFLAG_MPSAFE or CTLFLAG_NEEDGIANT (17 of many)	Pawel Biernacki	2020-02-26	1	-3/+6
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	r357614 added CTLFLAG_NEEDGIANT to make it easier to find nodes that are still not MPSAFE (or already are but aren’t properly marked). Use it in preparation for a general review of all nodes. This is non-functional change that adds annotations to SYSCTL_NODE and SYSCTL_PROC nodes using one of the soon-to-be-required flags. Mark all obvious cases as MPSAFE. All entries that haven't been marked as MPSAFE before are by default marked as NEEDGIANT Approved by: kib (mentor, blanket) Commented by: kib, gallatin, melifaro Differential Revision: https://reviews.freebsd.org/D23718 Notes: svn path=/head/; revision=358333
*	epoch_test: fix compile	Matt Macy	2018-07-15	1	-4/+6
\| \| \| \| \| \| \| \| \|	- update to new interface Reported by: manu Notes: svn path=/head/; revision=336300
*	epoch(9): Make epochs non-preemptible by default	Matt Macy	2018-05-18	1	-7/+7
\| \| \| \| \| \| \| \| \| \| \|	There are risks associated with waiting on a preemptible epoch section. Change the name to make them not be the default and document the issue under CAVEATS. Reported by: markj Notes: svn path=/head/; revision=333802
*	epoch: add non-preemptible "critical" variant	Matt Macy	2018-05-18	1	-1/+2
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	adds: - epoch_enter_critical() - can be called inside a different epoch, starts a section that will acquire any MTX_DEF mutexes or do anything that might sleep. - epoch_exit_critical() - corresponding exit call - epoch_wait_critical() - wait variant that is guaranteed that any threads in a section are running. - epoch_global_critical - an epoch_wait_critical safe epoch instance Requested by: markj Approved by: sbruno Notes: svn path=/head/; revision=333775
*	Test priority handling in epoch test.	Matt Macy	2018-05-11	1	-2/+12
\| \| \| \| \| \| \| \|	- Double the number of test threads to mp_ncpu*2 - Give each thread a different scheduling priority Notes: svn path=/head/; revision=333479
*	Add simple preempt safe epoch API	Matt Macy	2018-05-10	1	-0/+211
	Read locking is over used in the kernel to guarantee liveness. This API makes it easy to provide livenes guarantees without atomics. Includes epoch_test kernel module to stress test the API. Documentation will follow initial use case. Test case and improvements to preemption handling in response to discussion with mjg@ Reviewed by: imp@, shurd@ Approved by: sbruno@ Notes: svn path=/head/; revision=333466
