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

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.
