default n config ARMV7M_USEBASEPRI bool "Use BASEPRI Register" default n depends on ARCH_CORTEXM3 || ARCH_CORTEXM4 || ARCH_CORTEXM7 ---help--- Use the BASEPRI register to enable and disable interrupts. By default, the PRIMASK register is used for this purpose. This usually results in hardfaults when supervisor calls are made. Though, these hardfaults are properly handled by the RTOS, the hardfaults can confuse some debuggers. With the BASEPRI register, these hardfaults, will be avoided. For more details see http://www.nuttx.org/doku.php?id=wiki:nxinternal:svcall config ARCH_HAVE_CMNVECTOR bool config ARMV7M_CMNVECTOR bool "Use common ARMv7-M vectors" default n depends on ARCH_HAVE_CMNVECTOR ---help--- Some architectures use their own, built-in vector logic. Some use only the common vector logic. Some can use either their own built-in vector logic or the common vector logic. This applies only to ARMv7-M architectures. config ARMV7M_LAZYFPU bool "Lazy FPU storage" default n depends on ARCH_HAVE_CMNVECTOR ---help--- There are two forms of the common vector logic. There are pros and cons to each option: 1) The standard common vector logic exploits features of the ARMv7-M architecture to save the all of floating registers on entry into each interrupt and then to restore the floating registers when the interrupt returns. The primary advantage to this approach is that floating point operations are available in interrupt handling logic. Since the volatile registers are preserved, operations on the floating point registers by interrupt handling logic has no ill effect. The downside is, of course, that more stack operations are required on each interrupt to save and store the floating point registers. Because of the some special features of the ARMv-M, this is not as much overhead as you might expect, but overhead nonetheless. 2) The lazy FPU common vector logic does not save or restore floating point registers on entry and exit from the interrupt handler. Rather, the floating point registers are not restored until it is absolutely necessary to do so when a context switch occurs and the interrupt handler will be returning to a different floating point context. Since floating point registers are not protected, floating point operations must not be performed in interrupt handling logic. Better interrupt performance is be expected, however. By default, the "standard" common vector logic is build. This option selects the alternate lazy FPU common vector logic. config ARCH_HAVE_FPU bool default n config ARCH_HAVE_DPFPU bool default n config ARCH_FPU bool "FPU support" default y depends on ARCH_HAVE_FPU ---help--- Build in support for the ARM Cortex-M4 Floating Point Unit (FPU).
