* rtems: Relax mode checks in rtems_signal_catch()Sebastian Huber2021-03-191-2/+8
| | | | | | | | Check only for invalid modes if a valid handler is presented to rtems_signal_catch(). When NULL is used for the handler, ASR processing is disabled and the mode is not used. Update #4244.
* validation: Reduce source code/rodata sizeSebastian Huber2021-03-199-9795/+1271
| | | | | Use a common wording for the tests. Use the new templates for action requirements described in the RTEMS Software Engineering manual.

* rtems: Fix rtems_task_mode()Sebastian Huber2021-03-181-16/+22
| | | | | | Do the ASR and preemption mode change only if requested by the mode mask. The bug was introduced by 508f868237225a75e566d9fd304206363cfe441d.
* rtems: Improve semaphore create error checksSebastian Huber2021-03-161-6/+4
| | | | | | Do not mix checks for different error indicators (RTEMS_NOT_DEFINED and RTEMS_INVALID_NUMBER). This simplifies the specification of rtems_semaphore_create().
* rtems: Allow initially locked MrsP semaphoresSebastian Huber2021-03-163-13/+32
| | | | | | Rejecting initially locked MrsP semaphores was due to a limitiation of the early limitiation of the MrsP protocol. This limitation no longer exists.
* rtems: Require RTEMS_PRIORITY for MrsP semaphoresSebastian Huber2021-03-167-20/+28
| | | | | | | | | MrsP semaphores are a generalization of the priority ceiling semaphores for SMP configurations. Priority ceiling semaphores are required to use the priority task wait queue discipline. Require this discipline also for MrsP semaphores. Close #4347.
* sp14: Fix for SMP or robust thread dispatchSebastian Huber2021-03-161-0/+5
| | | | Close #4343.
* score: Add Thread_Configuration::cpu_time_budgetSebastian Huber2021-03-166-70/+49
| | | | | Move the CPU time budget to the thread configuration. This simplifies _Thread_Initialize().
* validation: Task create/constructSebastian Huber2021-03-163-0/+4
| | | | | Run the task create/construct tests also on validation test suite 1 which has exactly one processor configured.

* leon,tn-0018: work around GRLIB-TN-0018 errataDaniel Hellstrom2021-03-117-1/+106
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Overview ======== The errata is worked around in the kernel without requiring toolchain modifications. It is triggered the JMPL/RETT return from trap instruction sequence never generated by the compiler and. There are also other conditions that must must be true to trigger the errata, for example the instruction that the trap returns to has to be a JMPL instruction. The errata can only be triggered if certain data is corrected by ECC (inflicted by radiation), thus it can not be triggered under normal operation. For more information see: www.gaisler.com/notes Affected RTEMS target BSPs: * GR712RC * UT699 * UT700/699E The work around is enabled by defining __FIX_LEON3_TN0018 at build time. After applying the following GCC patch, GCC will set the define when compiling for an affected multilib: * GR712RC (-mcpu=leon3 -mfix-gr712rc) * UT700/UT699E (-mpcu=leon3 -mfix-ut700) * UT699 (-mcpu=leon -mfix-ut699) When building for another multilib and TN0018 is still required, it is possible to enable it on the RTEMS kernel configure line using the TARGET_CFLAGS (-D__FIX_LEON3FT_TN0018) or other by other means. The following GCC patch sets __FIX_LEON3FT_TN0018 for the affected RTEMS multilibs: --------- diff --git a/gcc/config/sparc/rtemself.h b/gcc/config/sparc/rtemself.h index 6570590..ddec98c 100644 --- a/gcc/config/sparc/rtemself.h +++ b/gcc/config/sparc/rtemself.h @@ -33,6 +33,8 @@ builtin_assert ("system=rtems"); \ if (sparc_fix_b2bst) \ builtin_define ("__FIX_LEON3FT_B2BST"); \ + if (sparc_fix_gr712rc || sparc_fix_ut700 || sparc_fix_ut699) \ + builtin_define ("__FIX_LEON3FT_TN0018"); \ } \ while (0) --------- Workaround Implementation ========================= In general there are two approaches that the workaround uses: A) avoid ECC restarting the RETT instruction B) avoid returning from trap to a JMPL instruction Where A) comes at a higher performance cost than B), so B) is used where posssible. B) can be achived for certain returns from trap handlers if trap entry is controlled by assembly, such as system calls. A) A special JMPL/RETT sequence where instruction cache is disabled temporarily to avoid RETT containing ECC errors, and reading of RETT source registers to "clean" them from incorrect ECC just before RETT is executed. B) The work around prevents JMPL after system calls (TA instruction) and modifies assembly code on return from traps jumping back to application code. Note that for some traps the trapped instruction is always re-executed and can therefore not trigger the errata, for example the SAVE instruction causing window overflow or an float instruction causing FPU disabled trap. RTEMS SPARC traps workaround implementation: NAME NOTE TRAP COMMENT * window overflow 1 - 0x05 always returns to a SAVE * window underflow 1 - 0x06 always returns to a RESTORE * interrupt traps 2 - 0x10..1f special rett sequence workaround * syscall 3 - 0x80 shutdown system - never returns * ABI flush windows 2 - 0x83 special rett sequence workaround * syscall_irqdis 4 - 0x89 * syscall_irqen 4 - 0x8A * syscall_irqdis_fp 1 - 0x8B always jumps back to FP instruction * syscall_lazy_fp_switch 5 - 0x04 A) jumps back to FP instruction, or to B) _Internal_error() starting with SAVE Notes: 1) no workaround needed because trap always returns to non-JMPL instruction 2) workaround implemented by special rett sequence 3) no workaround needed because system call never returns 4) workaround implemented by inserting NOP in system call generation. Thus fall into 1) when workaround is enabled and no trap handler fix needed. 5) trap handler branches into both 1) and returning to _Internal_error() which starts with a SAVE and besides since it shuts down the system that RETT should never be in cache (only executed once) so fix not necessary in this case. Any custom trap handlers may also have to be updated. To simplify that, helper work around assembly code in macros are available in a separate include file <libcpu/grlib-tn-0018.h>. Close #4155.

* leon: restart and load timer counter at initializationDaniel Hellstrom2021-03-111-1/+4
| | | | | | | | | | | | Without this smp05 and smpthreadlife01 tests may fail depending on how the boot loader initialized the GPTIMER. Before the time counter stopped counting when reaching zero, but tests could work since it could take 2^32 us before stopping. The timer driver will potentially overwrite this, but it happens later due to the initialization order having RTEMS_SYSINIT_CPU_COUNTER very early.

* leon3: avoid dependency on apbuart/timer driverDaniel Hellstrom2021-03-114-12/+30
| | | | | | | Moves drvmgr_drivers[] from amba.c to a separate file in order to avoid the dependecy on APBUART/GPTIMER drivers. This has an effect when user configured not to use timer or uart in their project.
* leon,greth: added support for variable sized descriptor table sizesDaniel Hellstrom2021-03-112-7/+16
| | | | | | | | | | The descriptor table size is equal to its alignment and set when configuring the HW IP through VHDL generics. This SW patch simply probes the HW how large the RX/TX descriptor tables are and adjusts accordingly. The number of descriptors actual used are controlled by other settings (rxDescs and txDescs) controlled by the user.

* leon,grcan: added support for GRCANFDDaniel Hellstrom2021-03-112-19/+692
| | | | | | | | | | | | | The new GRCAN_FD IP supports CAN FD standard and is mostly backwards compatible with GRCAN SW interface. The GRCAN driver have been extended to support the GRCANFD IP using the same driver. Additional functions have been added that uses a new CAN FD frame format and read/write/baud-rate functions that supports both GRCANFD and GRCAN. To keep the SW API fully backwards compatible with GRCAN, the old functions remain. Update #4324.

* leon,grspw: fix for SET_PACKET_SIZEDaniel Hellstrom2021-03-111-0/+7
| | | | | | | | | | When the DMA table has been allocated dynamically, the IOCTL_SET_PACKETSIZE will trigger an issue where pDev->rx and pDev->tx are not updated with the new DMA tables base address. Instead the old pointers are used. There is no point in reallocting the DMA tables because there is no configuration option to it. Therefore the DMA tables allocation is moved to a separate function never called from SET_PACKETSIZE.
