mocramis/x15.git - X15 microkernel perf module

Age	Commit message (Collapse)	Author
2018-02-24	New errno.h standard header	Richard Braun
	Use standard errno codes. This change also adds strerror to string.h.
2018-02-20	Rework the initialization operations of some kernel modules	Richard Braun
	In order to avoid workarounds that check whether a module is ready or not, break the initialization of some core modules into a bootstrap step for basic BSP initialization, and a setup step that completes initialization. Most users only need the bootstrap operation as a dependency, especially since scheduling isn't enabled yet.
2017-10-04	Fix some header inclusions	Richard Braun

2017-09-21	Merge branch 'xbuild'	Richard Braun

2017-09-21	New build system	Richard Braun
	The new build system, called xbuild, is a minimalistic kbuild-like make-based build system, also using kconfig for scalable configurations.
2017-09-20	kern/work: fix work_setup dependencies	Richard Braun

2017-09-06	Use new thread_check_intr_context function consistently	Richard Braun

2017-09-02	kern/thread: new preemption control macros	Richard Braun
	These new macros take care of disabling/restoring interrupts in the appropriate order.
2017-08-06	Fix dependencies on percpu_setup	Richard Braun

2017-07-13	Switch to initialization operations	Richard Braun

2017-06-25	Use the C11 alignas and noreturn macros	Richard Braun

2017-06-24	Move the CPU_L1_SIZE macro to x86/cpu module	Richard Braun

2017-06-10	Use log functions where appropriate	Richard Braun

2017-06-09	kern/work: fix manager wakeup	Richard Braun
	Commit 1b902346ce502870329bda19d92d317a21cab56e introduced a minor regression by also removing a check on the manager of a work pool, which is a pointer to a work_thread, and not directly a thread structure.
2017-06-03	kern/thread: improve thread_wakeup robustness	Richard Braun

2017-05-30	Move assert.h to the include directory	Richard Braun
	This turns assert.h into a standard header.
2017-04-29	New stdio.h standard header	Richard Braun
	Make kernel code obtain definitions for the printf family of functions through the inclusion of the standard stdio.h header.
2017-04-29	kern/printk: rename to printf	Richard Braun
	The printk functions are close enough to the printf ones to bear the same names.
2017-03-16	Update system counter names	Richard Braun
	Now that event counters have been replaced with system counters, drop the convention of naming the counter as the event it tracks.
2017-03-15	kern/work: move work_pool_init and work_setup to the .init section	Richard Braun

2017-03-15	kern/syscnt: replace the evcnt module	Richard Braun
	The syscnt module supports more generic counters, in addition to atomic access from any context on any architecture.
2017-03-14	Use the X15 namespace consistently for macros defined by autoconf	Richard Braun

2017-02-08	kern/thread: add wait channels	Richard Braun

2017-02-04	Clean up compilation	Richard Braun
	Instead of mixing standard headers and internal redefinitions of standard types, completely rely on the compiler for what is guaranteed for a free standing environment. This results in the removal of kern/stddef.h and kern/stdint.h. The kern/types.h header is reintroduced for the different (and saner) purpose of defining types not specified in standard C, namely ssize_t for now.
2017-01-29	kern/thread: rename "time-sharing" to "fair-scheduling"	Richard Braun

2017-01-24	kern/thread: add the THREAD_KERNEL_PREFIX macro	Richard Braun
	This macro is used to build kernel thread names.
2016-12-09	Force brackets around one-line conditional statements	Richard Braun
	This change was done using astyle, with a few manual editing here and there.
2014-12-10	kern/work: update call to kmem_cache_init	Richard Braun

2014-09-05	kern/work: use percpu variables	Richard Braun

2014-06-19	kern/work: synchronously destroy worker threads	Richard Braun

2014-06-18	Set threads as detached where applicable	Richard Braun

2014-06-18	kern/work: improve per-processor pools synchronization	Richard Braun
	Rely on disabling preemption only instead of a spin lock when accessing per-processor pools.
2014-06-17	kern/work: don't name work pools	Richard Braun

2014-06-17	kern/work: per-processor work pools	Richard Braun

2014-06-07	kern/work: add a comment back	Richard Braun
	That comment contains a TODO item that was removed by mistake.
2014-05-24	kern/work: rework worker id allocation	Richard Braun
	Replace the radix tree with a bitmap and adjust ID allocation. The use of a radix tree was overkill for this, and initially intended only as an example of how to use the data structure in the kernel.
2014-04-26	kern/work: use thread creation attributes accessors	Richard Braun

2014-01-02	Declare variables as read mostly where appropriate	Richard Braun

2013-07-05	kern/work: update rdxtree calls for 64-bit keys	Richard Braun

2013-06-10	kern/work: fix radix tree usage	Richard Braun
	Radix tree operations must be done with preemption enabled since they might allocate memory. Use a separate mutex to synchronize access to the tree.
2013-06-09	kern/work: use a radix tree for worker ID allocation	Richard Braun

2013-06-03	kern/work: new module	Richard Braun
	This module implements thread pools to concurrently process queues of deferred works.
