* score: Fix task stack initializationSebastian Huber2021-03-277-16/+41
| | | | | | | | | Do not adjust the stack area begin address since this may confuse the stack allocator and result in failed stack frees. Account for the alignment overhead in the stack space size estimate. Check that the stack size is in the expected interval.
* pwdgrp.c: Change to simply ignore return value from mkdir(/etc)Joel Sherrill2021-03-271-3/+1
| | | | | | | | | | | At this point in time, /etc can be created in multiple ways. There is a discussion (#4354) that would define a mechanism for instantiating a base file system with some flexibility for the set of directories included. For now, this particular mkdir() call can fail because /etc could already have been created by at least an initial filesystem image, the shell, or libbsd. closes #4382.
* dosfs: Use peek supportChristian Mauderer2021-03-263-5/+31
| | | | | | This speeds up reading fragmented files. Fix #3689
* libblock: Add rtems_bdbuf_peek()Christian Mauderer2021-03-267-60/+219
| | | | | | | | Adds a peek function that allows (for example) a file system to suggest the next blocks that should be used for read ahead. This can increase the read speed of fragmented files. Update #3689
* gen_uuid.c: Revert previous patch (597e4f476568a225d14dfaff02074cf269ad62ac)Joel Sherrill2021-03-241-8/+3
| | | | | | | | | | The patch was: gen_uuid.c: Fix two Unchecked return value from library errors CID 1049146: Unchecked return value from library in get_clock(). CID 1049147: Unchecked return value from library in get_random_fd(). Reopen #4280
* pwdgrp.c: Remove _Assert. /etc may already existRyan Long2021-03-231-1/+5
| | | | | | | | Removed the _Assert_unused_variable_equals macro due to /etc having already been created by the network stack initialization or an initial filesystem image. Closes #4282

* rtems-fdt/rtems-fdt.c: Fix bug in loop terminationG S Niteesh Babu2021-03-211-1/+1
| | | | | The while loop, loops infinitely in case of raw FDT data. The loop condition (size) is not modified during iterations.
* bsp/beagle: Ported Beagle pinmux driver to RTEMSG S Niteesh Babu2021-03-215-2/+163
| | | | | | | | | | The following files have been ported 1) ti_pinmux.c 2) ti_pinmux.h 3) am335x_scm_padconf.c 4) am335x_scm_padconf.h Update #3784
* bsps/beagle: Added SOC detection using FDTG S Niteesh Babu2021-03-215-6/+159
| | | | | Detects the SOC type using FDT and also replaces the ti_cpuid.h header in FreeBSD with custom one.
* bsp/beagle: Import Beagle pinmux from FreeBSDG S Niteesh Babu2021-03-214-0/+891
| | | | | | | | | | | | | | | | | | | This patch imports the beagle pinmux driver from FreeBSD into RTEMS. Previously this driver was placed in RTEMS-libBSD but this caused double initialization of few pins once during RTEMS initialization and second time during libBSD initialization. The following patches port the driver from FreeBSD to RTEMS and will remove the driver from RTEMS-libBSD. RTEMS Ticket Update: #3784 FreeBSD head: ca12b7e9534b10af022fed60c043984dbaf4003d The following files have been imported from FreeBSD: 1) freebsd/sys/arm/ti/am335x/am335x_scm_padconf.h 2) freebsd/sys/arm/ti/am335x/am335x_scm_padconf.c 3) freebsd/sys/arm/ti/ti_pinmux.h 4) freebsd/sys/arm/ti/ti_pinmux.c
* bsps/shared/ofw: Add rtems_ofw_is_node_compatibleG S Niteesh Babu2021-03-212-0/+29
| | | | | | | | This patch extends the RTEMS OFW API by adding rtems_ofw_find_device_by_compat This function checks if a node has the expected compatible property.
* bsps/arm/imxrt: Add FDT and FDT helper for QTMRChristian Mauderer2021-03-214-139/+293
| | | | | Makes it simpler to access the QTMR in an application via a FDT name or link in an application specific FDT entry.
* 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.
* build: Add test exclude for arm/lpc2362Sebastian Huber2021-03-191-0/+1

* 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().

* 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.
