2013-06-04 Niibe Yutaka <gniibe@fsij.org>
* chopstx.c (AIRCR): New.
(chx_init): Setting for PRIGROUP 2-bit:2-bit.
(sched): Unlock cpu_sched_lock on return to thread.
(preempt, chx_timer_expired, chx_handle_intr): Those can be
considered holding cpu_sched_lock (by its equal exception
priorities), thus no acquiring lock required.
2013-06-03 Niibe Yutaka <gniibe@fsij.org>
* chopstx.c (chx_spin_lock, chx_spin_unlock): Rename.
(chx_cpu_sched_lock, chx_cpu_sched_unlock): New.
* chopstx.c (chx_exit): Use R8.
2013-05-29 Niibe Yutaka <gniibe@fsij.org>
* entry.c (entry): Initialize data section.
* chopstx.c (svc): Implement race avoidance between
chx_handle_intr.
(chx_handle_intr): Increment ->ready. Put to ready queue
only when it's not running.
(chx_sched): Add an argument for race avoidance.
(chopstx_intr_wait): Fix race condition.
(chopstx_cond_broadcast): Fix initial value.
(chopstx_join): Check RET.
(chx_init): Initialize q_exit and q_join.
(chopstx_release_irq, chopstx_release_irq_thread): Enable IRQ on
release (as system reset default).
* board/board-olimex-stm32-h103.h (NEUG_ADC_SETTING2_*): Add.
* chopstx.c (chx_mutex_unlock, chopstx_exit): New.
(chopstx_mutex_unlock): Use chx_mutex_unlock.
(chopstx_cond_wait): Fix race condition.
2013-05-28 Niibe Yutaka <gniibe@fsij.org>
* chopstx.c (chopstx_intr_wait): Rename from chopstx_wait_intr.
(chopstx_usec_wait): Rename from chosptx_usleep.
(chopstx_cancel, chopstx_testcancel): New.
(idle): Moved from entry.c and use WFI if USE_WFI_FOR_IDLE.
2013-05-27 Niibe Yutaka <gniibe@fsij.org>
* chopstx.c (chx_fatal, chopstx_exit, chopstx_join): New.
(struct chx_thread): Independent member of state. Use bit fields.
(chx_timer_expired, chx_handle_intr): Check priority before
calling chx_request_preemption.
(chx_disable_intr): Clear pending interrupt too.
(chopstx_claim_irq): Rename from chopstx_intr_register.
(chopstx_release_irq): New.
(chopstx_join): Promote priority of thread to be joined.
2013-05-24 Niibe Yutaka <gniibe@fsij.org>
* chopstx.c (chx_request_preemption): Rename from chx_preempt.
* entry.c: "sys.h" is only for to new sys 2.0, keeping
compatibility to 1.0, it is if-def out now.
2013-05-22 Niibe Yutaka <gniibe@fsij.org>
* chopstx.c (chx_enable_intr, chx_disable_intr): Implement.
(chx_set_intr_prio): New.
(chx_handle_intr): Use list to register interrupt threads.
(chx_init): Set PendSV priority (as minimum: bigger).
* entry.c (vector_table): set chx_handle_intr for all interrupts.
2013-05-21 Niibe Yutaka <gniibe@fsij.org>
* Initial commit.
