Move _CPU_Fatal_halt() declaration to <rtems/score/cpuimpl.h> and make sure it
is a proper declaration of a function which does not return. Fix the type of
the error code. If necessary, add the implementation to cpu.c. Implementing
_CPU_Fatal_halt() as a function makes it possible to wrap this function for
example to fully test _Terminate().
Do not return a status code in bsp_interrupt_facility_initialize() since this
leads to unreachable code in bsp_interrupt_initialize(). Use RTEMS_DEBUG
assertions in bsp_interrupt_facility_initialize() if necessary.
Add rtems_interrupt_entry_remove(). Split up irq-generic.c into several files.
In particular, place all functions which use dynamic memory into their own
file.
Add optional macros to let the BSP customize the vector installation after
installing the first entry and the vector removal before removing the last
entry:
* bsp_interrupt_vector_install()
* bsp_interrupt_vector_remove()
Use these new customization options in the m68k/genmcf548x BSP so re-use the
generic interrupt controller support.
Update #3269.
Add rtems_interrupt_raise_on() and rtems_interrupt_clear().
Add a default implementation which just returns RTEMS_UNSATISFIED for
valid parameters.
Update #3269.
Assert BSP_INTERRUPT_VECTOR_MAX + 1 == BSP_INTERRUPT_VECTOR_COUNT.
After building all BSPs with this patch, BSP_INTERRUPT_VECTOR_MAX can be
removed and replaced by BSP_INTERRUPT_VECTOR_COUNT. The
BSP_INTERRUPT_VECTOR_COUNT allows a default implementation which supports no
interrupt vector at all. Using COUNT instead of MAX may avoid some
interpretation issues, for example is the maximum value a valid vector number
or not.
Update #3269.
Remove BSP_INTERRUPT_VECTOR_MIN and unconditionally let interrupt vector
numbers start with zero.
The BSP_INTERRUPT_VECTOR_MIN == 0 invariant was tested by the previous commit
and building all BSPs.
Update #3269.
- Fixes timeout for smpipi01 where:
+ Main thread sends perform jobs to worker cpu while it is already
performing jobs
+ Interrupt on worker cpu performs jobs, but with empty job list
+ Worker cpu continues to execut previous job and adds new job list
to itself, which is never performed, since the interrupt has already
been handled
+ Main thread blocks forever on barrier D
- Do not forward Clock_isr through Clock_driver_support_at_tick as this
will cause every processor to send IPIs with Clock_isr therby creating
an infinie loop
- Instead the processor handling the clock interrupt causes all other
processors to call rtems_timecounter_tick to update their tick count
Create a GS segment in the GDT for each processor for storing TLS.
This makes the GDT in startAP.S obsolete as all processors now share the
same GDT, which is passed to each AP at startup.
The correct segment for each processor is calculated in cpu_asm.S.
Update #3335
start16.S is now only used for SMP configurations to start the
application processors.
This commit removes all unnecessary parts for this job,
i.e. video conssole initalisation, A20 gate activation
and all non-AP related code.
Update #3335
Add a simplified path evaluation function IMFS_eval_path_devfs() for a
device only IMFS configuration.
The code size can be further reduced by the application if it disables
the support for legacy IO drivers via:
#define CONFIGURE_IMFS_DISABLE_MKNOD
#define CONFIGURE_IMFS_DISABLE_MKNOD_DEVICE
Obsolete CONFIGURE_MAXIMUM_DEVICES. Remove BSP_MAXIMUM_DEVICES.
Update #3894.
Update #3898.
The work area initialization was done by the BSP through
bsp_work_area_initialize(). This approach predated the system
initialization through the system initialization linker set. The
workspace and C program heap were unconditionally initialized. The aim
is to support RTEMS application configurations which do not need the
workspace and C program heap. In these configurations, the workspace
and C prgram heap should not get initialized.
Change all bsp_work_area_initialize() to implement _Memory_Get()
instead. Move the dirty memory, sbrk(), per-CPU data, workspace, and
malloc() heap initialization into separate system initialization steps.
This makes it also easier to test the individual initialization steps.
This change adds a dependency to _Heap_Extend() to all BSPs. This
dependency will be removed in a follow up change.
Update #3838.
- Use CamelCase as it is not used in our C code. Enables simple search and
replace.
- Prefix with "RTEMS" to aid deployment and integration. It aids
searching and sorting.
Update #3706.
Add and use <machine/rtems-bsd-kernel-space.h> and
<machine/rtems-bsd-user-space.h> similar to the libbsd to avoid command
line defines and defines scattered throught the code base.
Simplify cpukit/libnetworking/Makefile.am.
Update #3375.
