Using rtems_interrupt_entry_install() instead of
rtems_interrupt_handler_install() avoids a dependency on the dynamic memory
allocation.
Use Interrupt Manager directives instead of a BSP-specific API. Use inline
functions. In SMP configurations, set an affinity to all online processors and
raise the interrupt on the current processor.

The <leon.h> header file contains a lot of implementation details. Hide them
from <bsp.h>.

Fully support the interrupt extension API to set/get the interrupt affinity.
Remove LEON3_irq_to_cpu which defined the interrupt to processor mapping in a
BSP-specific way.

This function is not performance critical. There is no need to
implement it inline.

The fix to address CID 1399742 (NO_EFFECT) in commit
f8b6359415404540864f809cbcffb8c2200261e1 introduced a bug since
LEON3_IrqCtrl_EIrq == -1 in case no extended interrupts are supported by
the interrupt controller. Fix this by checking for
LEON3_IrqCtrl_EIrq > 0.
In addition, interrupt number 0 is reserved and should not be used.

Move _ISR_Handler() to a separate file since it is now only used if a handler
is installed by _CPU_ISR_install_raw_handler().
Statically initialize the traps for external interrupts to use the new
_SPARC_Interrupt_trap() which directly dispatches the interrupt handlers
installed by rtems_interrupt_handler_install() via the BSP-provided
_SPARC_Interrupt_dispatch().
Since the trap table is now fully statically initialized, there is no longer a
dependency on the Cache Manager in the default configuration.
Update #4458.

Avoid using set_vector() which depends on _ISR_Vector_table(). Prepare for a
statically initialized trap table.

Statically initialize the trap table in start.S to jump to _SPARC_Bad_trap()
for all unexpected traps. This enables a proper RTEMS fatal error handling
right from the start. Do not rely on the stack and register settings which
caused an unexpected trap. Use the ISR stack of the processor to do the fatal
error handling. Save the full context which caused the trap. Fatal error
handler may use it for error logging.
Unify the _CPU_Exception_frame_print() implementations and move it to cpukit.

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.

Replace the global variable ambapp_plb with a function to allow an automatic on
demand initialization.
|
|
|
|
|
|
|
| |
There is not need to check that vector >= BSP_INTERRUPT_VECTOR_MIN since
BSP_INTERRUPT_VECTOR_MIN is zero and vector is unsigned.
This fix relates to CID 1399742 (NO_EFFECT).

Provide RTEMS_NO_RETURN also in case RTEMS_DEBUG is defined to prevent errors
like this:
error: no return statement in function returning non-void [-Werror=return-type]
Use C11 and C++11 standard means to declare a no-return function.

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.

- 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.

In order to simplify the use of CPU counter values it is beneficial to
have monotonic increasing values within the range of the CPU counter
ticks data type, e.g. 32-bit unsigned integer. This eases the use of
CPU counter timestamps in external tools which do not know the details
of the CPU counter hardware. The CPU counter is the fastest way to get
a time on an RTEMS system.
Such a CPU counter may be also used as the timecounter. Use it on SPARC
for this purpose to simplify the clock drivers.
Update #3456.

A speciality of the RTEMS build system was the make preinstall step. It
copied header files from arbitrary locations into the build tree. The
header files were included via the -Bsome/build/tree/path GCC command
line option.
This has at least seven problems:
* The make preinstall step itself needs time and disk space.
* Errors in header files show up in the build tree copy. This makes it
hard for editors to open the right file to fix the error.
* There is no clear relationship between source and build tree header
files. This makes an audit of the build process difficult.
* The visibility of all header files in the build tree makes it
difficult to enforce API barriers. For example it is discouraged to
use BSP-specifics in the cpukit.
* An introduction of a new build system is difficult.
* Include paths specified by the -B option are system headers. This
may suppress warnings.
* The parallel build had sporadic failures on some hosts.
This patch removes the make preinstall step. All installed header
files are moved to dedicated include directories in the source tree.
Let @RTEMS_CPU@ be the target architecture, e.g. arm, powerpc, sparc,
etc. Let @RTEMS_BSP_FAMILIY@ be a BSP family base directory, e.g.
erc32, imx, qoriq, etc.
The new cpukit include directories are:
* cpukit/include
* cpukit/score/cpu/@RTEMS_CPU@/include
* cpukit/libnetworking
The new BSP include directories are:
* bsps/include
* bsps/@RTEMS_CPU@/include
* bsps/@RTEMS_CPU@/@RTEMS_BSP_FAMILIY@/include
There are build tree include directories for generated files.
The include directory order favours the most general header file, e.g.
it is not possible to override general header files via the include path
order.
The "bootstrap -p" option was removed. The new "bootstrap -H" option
should be used to regenerate the "headers.am" files.
Update #3254.
