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.
Update #3269.
Skip the data cache initialization if we are a secondary processor.
The bug was introduced by e164df5e33 and
did not show up in tests using Qemu since the data cache behaviour is
not emulated.
Calling the memory FLASH and EXTRAM instead of FLEXSPI and SDRAM makes
it simpler to support other types of external RAM. This patch also
removes some of the calculations and improves names and documentation to
avoid pitfalls. It removes a unnecessary memory definition.
Update #4180
This reverts commit 10041a4cfc.
This type of configuration does not belong in RTEMS and is better
constrained to libbsd where the defines are actually being used.
The fix to address CID 1399742 (NO_EFFECT) in commit
f8b6359415 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.
The GICv3 support is shared between AArch32 and AArch64. For AArch32,
the new AARCH64_IS_NONSECURE is never defined. Use ARM_MULTILIB_ARCH_V4
instead.
This issue was introduced by 76c6caad52.
There is still a change in bsp_interrupt_vector_enable() for AArch32
compared to the version before 76c6caad52.
The existing fix for the ZynqMP UART hardware bug only caught the vast
majority of instances where it could occur. To fully fix the data
corruption, this fix must be applied after every baud rate change. This
makes the logic reset and kick apply in any locations where the baud
rate could be changed.
The Cortex-R52 does not support cache coherency and the shareable memory
attribute. If a region is configured to be shareable, then it falls
back to use non-cacheable memory.
Update #4202.
Provide the options necessary to enable any combination of CGEM ethernet
interfaces in LibBSD. The default is still CGEM3, so this should
continue to operate as expected on typical Zynq Ultrascale+ MPSoC
development hardware.
This change allows for the migration of higher priority tasks on the
arrival of a lower priority task limited by affinity constraints.
Change license to BSD-2-Clause according to file history and
re-licensing agreement.
Update #3053.
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.
Add bsp_interrupt_handler_dispatch_unchecked() as an alternative to
bsp_interrupt_handler_dispatch(). It may be used if the caller can ensure that
the vector number is valid.
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.
Update #4459.
Move _CPU_ISR_install_raw_handler() and _CPU_ISR_install_vector() to separate
files. The goal is to make their use optional.
Update #4458.
Update #4459.
This makes it easier to review start.o and set break points to trap table
entries. This change was checked by inspecting the trap table in start.o with
objdump.
Update #4458.
The _ISR_Handler_initialization() does not touch the _ISR_Vector_table[]. Move
the definition of _ISR_Vector_table[] to a separate file.
Change license to BSD-2-Clause according to file history and re-licensing
agreement.
Update #3053.
This CPU port macro was not used. Since the _ISR_Vector_table[] is statically
allocated, CPU ports could initialize this table in _CPU_Initialize() if
necessary. Remove _CPU_Initialize_vectors() to simplify the CPU port
interface.
