Splits functionality so that reading from the dtb file is distinct from
loading it into memory. This allows directly loading a dtb from memory
instead of from a file.
The number of external interrupts can be configured through the FDT.
Read it during PLIC initialization and use that to determine the max
valid vector number.
The previous addition of s-mode support avoided touching the PLIC
registers and only allowed limited use of software interrupts for SMP
IPIs. This enables the PLIC in s-mode mapping the registers with the MMU
and unifying some aspects of the m-mode and s-mode implementations.
Updates #3337
Update to tms570-sci.c (commit af77d28) puts a gate to check
requests for non 8-bit bytes and CREAD not set, we therefore
must expclitily set them now.
- Changed the interrupt attributes so extended vectors
report can_raise as false.
- Changed the bsp_interrupt_raise to return
RTEMS_UNSATISFIED for extended vectors 16-31.
- BSP-specific validation for gr712rc and gr740
were added to exercised the extended vectors, and
check that the right interrupt handler is called.
Updates #4846.
Adds invalidation of cache (using
rtems_cache_invalidate_multiple_instruction_lines which is
included in the wrapper function
rtems_cache_instruction_sync_after_code_change.
This is to ensure full syncing of the I-cache after copying
instructions (in .fast_text into RAM with
bsp_start_copy_sections_compact in bspstarthooks.c
The smpclock01 test relies on tight synchronization between cores and it
checks cross-core Watchdog.ticks. On some targets the cores can become
de-synchronized so that the tick counts are not reliable. Slowing the
tick rate down seems to help this problem.
Add post-2100 validation checks in spclock_err02
without increasing runtime and remove excessive prints.
The test verifies century and leap-year rules via RTEMS
clock APIs and gmtime()/mktime() for future years.
Fixes#5507
_BM(x) produces 64-bit values which are implicitly converted to int
in reloc_target_bitmask. For x = 32, this causes truncation from
4294967295 to -1 on 32-bit targets, triggering -Woverflow.
Used uint32_t and cast the result to avoid implicit narrowing.
Fixes#5557
Fix parity handling in zynq_uart_set_attributes() by clearing existing
parity bits before setting a new mode instead of always ORing PAR_NONE,
which caused incorrect or ignored parity; also fix inverted PARODD logic
and add ZYNQ_UART_MODE_PAR_MASK to manage the parity field correctly.
Fixes#5554
The rtems_test_spin_for_ticks( x ) executes one partial tick and the
remaining x - 1 as complete ticks. Some tests assumed it executed x
complete ticks. Fix those tests.
Fixes#5575.
Fix incorrect comparison between fdt_getprop() length (bytes)
and address cells count.
The check now uses ac * sizeof(uint32_t) to avoid
reading invalid data.
Also change FDT pointer type from const char * to const void *
to match libfdt API.
No functional changes.
CAN controllers need a running worker task to function. Check if
the task is actually started and return NULL (and free already allocated
resources) if it fails.
Also assert if cleanup functions fail.

- leon3 interrupt vector 15 is non-maskable and should
not be reported as disable-capable.
- added leon3_interrupt_is_maskable function, and
used it to set can_disable and maybe_disable in
bsp_interrupt_get_attributes().
- added verification for non-maskable vectors in
bsp_interrupt_vector_disable(), which is rejected
with error RTEMS_UNSATISFIED.
Updates #4830.
shared/vme/README.md had references to set_vector() for installing
isr during vme driver setup. They have been replaced by
rtems_interrupt_handler_install().
Updates #5215
This code was flagged as maybe-uninitialized when compiling at -Og.
The underlying problem was functional code in an assert(). If
compiled with asserts disabled, there would have been no mutex
lock/unlock. Changed the macros to obtain and release the mutex
independent of assert() being enabled or not and switched to using
the RTEMS assert _Assert() which lets this check follow the
RTEMS_DEBUG setting.
The variables start and size were used in the return statement
even if none of the if's set them. Defaulted them to zero which
results in returning NULL on error which was expected anyway.
Creates level-2 mappings for the configured RAM region and for the
MMIO device region. Each of these two regions is configured as a
level-1 table with 2 MiB superpages.
Updates #5540.
The comparison of a register to see if it holds a number less than
3 needs to be unsigned since the register is otherwise expected to
hold an address that could have the most significant bit set.
Fixes#5561
Include contrib/riscv-opcodes/encoding.h from riscv-utility.h and
remove outdated contents from riscv-utility.h
This will allow the include guards to work properly for users (or HAL code)
that also use the encoding.h file, while still allowing us to provide
additional customization or extension of encoding.h macros.
Disable PCI/PCIe and other buses I/O mapped access
because rtems/cpukit build is not allowed to access
BSP specific headers during build.
rtems/bsps/i386/include/i386_io.h
Cannot be used.
This is temporal workaround for
rtems/rtos/rtems#5563

Noticed TMS570_CRC_REGH1 was mislabeled as a low registers, and
decided to clean up the other out-of-date comments along the way.
No code changes - documentation only.
Issue: no issues opened for minor documentation change
This commit adds support for a stand alone SJA1000 CAN controller. This
is classical CAN only capable controller, so no FD support here. The
driver's implementation is similar to CTU CAN FD, thus interrupt handler
triggers a semaphore in main worker thread that takes care of handling
interrupts and receiving and sending messages.
The controller utilizes its one TX buffer for sending messages with
abort function available if higher priority message is present in
the software queue.
