spec: Test CPU performance Measure the runtime of 1000 no-operation instructions. This may help to investigate runtime measurement variations which do not result from code generation or source code changes. The runtime measurement of a function which does nothing and just returns gives an estimate of the measurement overhead.

bsps/xil: Adjust Xilinx support code for Cortex-R5 This fixes some issues in the Xilinx support code that are critical to support the Cortex-R5F cores present in my Xilinx SoCs?. The imported Cortex-R5 xil_cache.c matches the existing information in bsps/shared/xil/VERSION.

cpukit/aarch64: Resolve warnings with ILP32 ABI Casts from uint64_t to void* must go through a uintptr_t cast to avoid warnings when building with the ILP32 ABI since this is otherwise an implicit truncation to 32bits for a pointer.

arm: Use a valid signed integer constant Enumerators are restricted to signed integers in some C standards.

psx13: Fix use of uninitialized variable warning
12:14 Changeset in rtems [ee63681a] by Sebastian Huber <sebastian.huber@…>
tests: Add header for RTEMS test printer The <rtems/test-info.h> header file is required for every RTEMS test program. Move the RTEMS test printer support to a dedicated header file <rtems/test-printer.h>. This removes an unnecessary dependency to the RTEMS printer support in <rtems/test-info.h>. Tests using the RTEMS Testing Framework no longer depend on the <rtems/printer.h>.

18:16 Changeset in rtems [99c637f] by Kinsey Moore <kinsey.moore@…>
cpukit/jffs2: Avoid use of off-chain semantics This reworks the JFFS2 delayed work queue to avoid use of on-chain/off-chain semantics since they vary in behavior under RTEMS_DEBUG and are not guaranteed to be safe to use in SMP systems. This adds all delayed work structs to the chain on FS init and does not remove them until umount. Updates #4956
16:58 Ticket #4956 (Deadlock caused by locking inversion in JFFS2) created by Kinsey Moore

07:21 Changeset in rtems [1c36971d] by Sebastian Huber <sebastian.huber@…>
sparc: Fix stack corruption Fix a potential stack corruption in uniprocessor configurations during start multitasking. The system initialization uses the interrupt stack. A first level interrupt shall never interrupt a context which uses the interrupt stack. Such a use would lead to stack corruption and undefined system behaviour. Unfortunately, in uniprocessor configurations this was the case. Multiprocessing is started using _CPU_Context_restore(). The caller of this function (_Thread_Start_multitasking()) uses the interrupt stack. Later we have in cpukit/score/cpu/sparc/cpu_asm.S: mov %g1, %psr ! restore status register and ! ENABLE TRAPS ld [%o1 + G5_OFFSET], %g5 ! restore the global registers ld [%o1 + G7_OFFSET], %g7 ! Load thread specific ISR dispatch prevention flag ld [%o1 + ISR_DISPATCH_DISABLE_STACK_OFFSET], %o2 ! Store it to memory later to use the cycles ldd [%o1 + L0_OFFSET], %l0 ! restore the local registers ldd [%o1 + L2_OFFSET], %l2 ldd [%o1 + L4_OFFSET], %l4 ldd [%o1 + L6_OFFSET], %l6 ! Now restore thread specific ISR dispatch prevention flag st %o2, [%g6 + PER_CPU_ISR_DISPATCH_DISABLE] ldd [%o1 + I0_OFFSET], %i0 ! restore the input registers ldd [%o1 + I2_OFFSET], %i2 ldd [%o1 + I4_OFFSET], %i4 ldd [%o1 + I6_FP_OFFSET], %i6 ldd [%o1 + O6_SP_OFFSET], %o6 ! restore the output registers Between the ENABLE TRAPS and the restore of the output registers, we still use the stack of the caller and interrupts may be enabled. If an interrupt happens in this code block, the interrupt stack is concurrently used which may lead to a crash. Fix this by adding a new function _SPARC_Start_multiprocessing() for uniprocessor configurations. This function first sets the stack pointer to use the stack of the heir thread. Close #4955.

21:02 Changeset in rtems-libbsd [f0fe043]6-freebsd-12 by Kinsey Moore <kinsey.moore@…>
rtemsbsd/libio: Handle invalid descriptors The documentation for this function suggests that it can handle invalid descriptors safely. This change allows negative descriptors to be handled without a crash.
19:28 Changeset in rtems [41d43ce] by Kinsey Moore <kinsey.moore@…>
bsps/xnandpsu: Ensure buffer cache sync When a buffer is modified by both hardware components such as DMA and by software components, the buffer cache state must be kept in sync so that data is not accidentally thrown away during future invalidations.
19:23 Changeset in rtems [2b5526aa] by Kinsey Moore <kinsey.moore@…>
bsps/xnandpsu: Don't rely on usleep for polling When polling hardware registers in high performance situations, don't rely on usleep or other standard sleep functions since they will necessarily rely on kernel ticks to be woken up. This can easily cause an immense reduction in throughput.

build: Remove enabled-by special case Doing the enabled-by processing just for the ldflags and just for the link custom commands is confusing. Use an option instead which is intended to be used for such use cases.
