Right after a "msr basepri_max, %[basepri]" instruction an interrupt
service may still take place (observed at least on Cortex-M7). However,
pendable service calls that are activated during this interrupt service
may be delayed until interrupts are enable again. The
_ARMV7M_Pendable_service_call() did not check that a thread dispatch is
allowed. Move this test from _ARMV7M_Interrupt_service_leave() to
_ARMV7M_Pendable_service_call().
Update #3060.
Change bsp_interrupt_vector_enable() and bsp_interrupt_vector_disable()
to not return a status code. Add bsp_interrupt_assert() and use it to
validate the vector number in the vector enable/disable implementations.
Display the scheduler name instead of the current CPU in the "task"
shell command. The current CPU could be misleading in case locking
protocols are involved. The "cpuuse" command can be used to obtain the
current CPU.
Update ticket #2891 and my GSOC project
add c/src/lib/libbsp/arm/beagle/i2c/bbb-i2c.c
modify c/src/lib/libbsp/arm/beagle/include/i2c.h
modify c/src/lib/libbsp/arm/beagle/include/bbb-gpio.h
modify c/src/lib/libcpu/arm/shared/include/am335x.h
modify c/src/lib/libbsp/arm/beagle/Makefile.am
Now can read the EEPROM by i2c, the test application link is: https://github.com/hahchenchen/GSOC-test-application
According to manual, the used operations (Clean Line by PA, Clean and
Invalidate Line by PA, Cache Sync) are atomic and do not require
locking.
Update #3007.
For whatever reason FreeBSD renames several functions provided by
<arpa/inet.h> and uses weak references to provide the standard function
names. This causes problems on targets lacking proper support for weak
references. We do not need this function renaming on RTEMS.lk:x
Update #2833.
There is no need to save the thread pointer in _CPU_Context_switch()
since it is a thread invariant. It is initialized once in
_CPU_Context_Initialize().
Enable/disable vector routines now check for a valid vector. Without
these guards, the enable/disable vector routines will not work with the
interrupt server.
The original CPU_COPY() support of Newlib <sys/cpuset.h> had the
parameters in the wrong order. This is fixed in Newlib since
2017-05-22.
Update #3023.
