2021-03-11leon,tn-0018: work around GRLIB-TN-0018 errataDaniel Hellstrom1-0/+1
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.
2021-03-11leon3: avoid dependency on apbuart/timer driverDaniel Hellstrom1-0/+1
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.

2021-03-09build: Fix broken linkSebastian Huber1-1/+1
2021-03-08spec/aarch64: Enable previously disabled testsAlex White2-18/+2
This enables several testsuites that were initially disabled during development.
2021-03-05spec/aarch64: Rename ZynqMP QEMU BSPsKinsey Moore3-3/+3
The current ZynqMP BSPs don't have _qemu in their name as do all other RTEMS BSPs that are specifically made to run on QEMU. This fixes the naming for those ZynqMP BSP variants for easier identification.
2021-03-05spec: Move hypervisor start for use by AArch64Kinsey Moore2-1/+1
AArch64 on hardware is often started at EL2 instead of EL1 from either u-boot or a first stage bootloader. This allows RTEMS to drop from EL2 execution to EL1 to operate as normal.

2021-03-05bsps/aarch64: Resolve usage of SUBALIGN()Kinsey Moore2-2/+0
Remove usage of SUBALIGN() in aarch64 linkcmds which works around a difference in behavior on AArch64 platforms. This is no longer necessary since alignment is now enforced explicitly. Closes #4178.

2021-02-13Update motorola_power to irq-generic interrupt managementChris Johns2-2/+3
- Add support to the BSP to enable irq-generic management - Update the powerpc shared irq code to support irq-generic. This is an opt in option for existing powerpc bsps. This change should be simpler now - Fix a number of issues in ISA IRQ controller handling by porting fixes from the i386 (PC) BSP Closes #4238 Closes #4239

Rename _Nios2_ISR_Dispatch_with_shadow_non_preemptive() in _Nios2_ISR_Dispatch_with_shadow_register_set(). Remove _Nios2_ISR_Dispatch_with_shadow_preemptive().

GCC 11 uses DWARF 5 by default.
2021-01-22bsps/shared: Build fsl-edma only for certain BSPChristian Mauderer3-5/+20
Move the Freescale EDMA driver to it's own object and build it only for the BSP that is currently using it.
2021-01-21bsps/imxrt: Add ioctl to LPSPI to get registersChristian Mauderer1-0/+1
This allows an application to get the registers of the LPSPI. That is usefull for applications that want to use DMA for a very specialized and highly optimized communication. Update #4180
2021-01-21bsps/shared: Adapt fsl-edma driver for imxrtChristian Mauderer3-0/+23
Note: The changes have been done with portability in mind. The driver should (in theory) be able to replace the original one in the MPC BSPs too. For full compatibility an adaption layer and especially a test would be necessary. Because both are missing, don't integrate it into the MPC BSP now. Update #4180
2021-01-04bsp/stm32h7: Split console configurationSebastian Huber1-0/+10
This allows applications to individually provide configuration structures. Update #4209.
2021-01-04bsp/stm32h7: Split start configurationSebastian Huber1-1/+5
