545cfada38 This commit removes CONFIG_ARCH_INT_DISABLEALL. In the normal course of things, interrupts must occasionally be disabled using the up_irq_save() inline function to prevent contention in use of resources that may be shared between interrupt level and non-interrupt level logic. Now the question arises, if we are using BASEPRI to disable interrupts and have high priority interrupts enabled (CONFIG_ARCH_HIPRI_INTERRUPT=y), do we disable all interrupts except SVCall (we cannot disable SVCall interrupts). Or do we only disable the "normal" interrupts? 
If we are using the BASEPRI register to disable interrupts, then the answer is that we must disable ONLY the "normal interrupts".  That is because we cannot disable SVCALL interrupts and we cannot permit SVCAll interrupts running at a higher priority than the high priority interrupts (otherwise, they will introduce jitter in the high priority interrupt response time.)

Hence, if you need to disable the high priority interrupt, you will have to disable the interrupt either at the peripheral that generates the interrupt or at the NVIC.  Disabling global interrupts via the BASEPRI register cannot effect high priority interrupts.

5fe6981c9a Squashed commit of the following: 
libs/libc/pthread/pthread_spinlock.c:  Resolve several TODO issues by accessing up_testset() via the boardctl() interface rather than attempting to call it directly.

    configs/boardctl.c, include/sys/boardctl.h:  Add access to architecture-specific up_testset() via boardctl().

    arch/Kconfig's, sched/Kconfig, and include/nuttx/spinlock.h:  Spinlocks are not available unless the architecture supports the up_testset() operation.

81bef6cccf arch/Kconfig and arm/src/armv7-m/Kconfig: ARCH_HIPRI_INTERRUPT shouldn't select ARMV7M_USEBASEPRI. First because that is a violation of the layered nature of the Kconfig architecture, but also because then Kconfig will generated errors when high priority interrupts are used with other architectures. 2019-01-26 07:21:18 -06:00

    arch/, include/nuttx, sched/sched:  Add the garbage collection hook so each architecture can do custom memory cleanup if necesary.

92b925ba02 arch/Kconfig: Bring-up features should also depend on CONFIG_DEBUG_FEATURES. I missed a bring-up feature that is specific to the ESP32. I hope that the ESP32 ports still work as intended! It depended on some of these bring-up settings in the header file. I moved the definitions to the ESP32 defconfig files. 2018-08-19 15:38:06 -06:00

201a32cf8c Add support for the RISC-V architecture and configs/nr5m100-nexys4 board. I will be making the FPGA code for this available soon (within a week I would say). The board support on this is pretty thin, but it seems like maybe a good idea to get the base RISC-V stuff in since there are people interested in it. 2016-10-16 09:47:07 -06:00
