2019-01-08target/aarch64: add support for multi-architecture gdbAntonio Borneo1-0/+5
GDB can be built for multi-architecture through the command ./configure --enable-targets=all && make Such multi-architecture GDB requires the target's architecture to be selected either manually by the user through the GDB command "set architecture" or automatically by the target description sent by the remote target (i.e. OpenOCD). Commit e65acd889c61a424c7bd72fdee5d6a3aee1d8504 ("gdb_server: add support for architecture element") already provides the required infrastructure to support multi-architecture gdb. aarch64-linux-gnu-gdb 8.2 uses "aarch64" as default architecture, but also supports the value "aarch64:ilp32" and all the values supported by arm-none-eabi-gdb. These values can be displayed on arm gdb prompt by typing "set architecture " followed by a TAB for autocompletion. Set the gdb architecture value for aarch64 target to "aarch64".

2018-06-04Rework/update ARM semihostingLiviu Ionescu1-1/+5
In 2016, ARM released the second edition of the semihosting specs ("Semihosting for AArch32 and AArch64"), adding support for 64-bits. To ease the reuse of the semihosting logic for other platforms (like RISC-V), the semihosting code was isolated from the ARM target and updated to the latest specs. The new code is already in use since January (in GNU MCU Eclipse OpenOCD) and no problems were reported, neither for ARM nor for RISC-V targets, after more than 7K downloads. The 2 new files were formatted with uncrustify.

Add new AARCH64 target and ARMv8 support files. This is an instantiation from the cortex_a files but modified to support 64bit ARMv8. Not all features are complete, notably breakpts and single stepping are not yet implemented. Currently it lets you halt of the processors, resume, dump cpu registers, read/write memory and getting a stack trace with gdb. > halt invalid mode value encountered 5 target state: halted unrecognized psr mode: 0x5 target halted in ARM state due to debug-request, current mode: UNRECOGNIZED cpsr: 0x600001c5 pc: 0x00093528 MMU: disabled, D-Cache: disabled, I-Cache: disabled > targets TargetName Type Endian TapName State -- ------------------ ---------- ------ ------------------ ------------ 0* cpu0 aarch64 little cpu.dap halted > reg ===== arm v8 registers (0) r0 (/64): 0x00000000FFFFFFED (dirty) (1) r1 (/64): 0x00000000F76E4000 (2) r2 (/64): 0x0000000000000000 (3) r3 (/64): 0x0000000000010000 (4) r4 (/64): 0xFFFFFFC06E2939E1 (5) r5 (/64): 0x0000000000000018 (6) r6 (/64): 0x003A699CFB3C8480 (7) r7 (/64): 0x0000000053555555 (8) r8 (/64): 0x00FFFFFFFFFFFFFF (9) r9 (/64): 0x000000001FFEF992 (10) r10 (/64): 0x0000000000000001 (11) r11 (/64): 0x0000000000000000 (12) r12 (/64): 0x00000000000000F0 (13) r13 (/64): 0x00000000EFDFEAC8 (14) r14 (/64): 0x00000000F6DDA659 (15) r15 (/64): 0x0000000000000000 (16) r16 (/64): 0xFFFFFFC0000F9094 (17) r17 (/64): 0x0000000000000000 (18) r18 (/64): 0x0000000000000000 (19) r19 (/64): 0xFFFFFFC00087C000 (20) r20 (/64): 0x0000000000000002 (21) r21 (/64): 0xFFFFFFC000867C28 (22) r22 (/64): 0xFFFFFFC000916A52 (23) r23 (/64): 0xFFFFFFC00116D8B0 (24) r24 (/64): 0xFFFFFFC000774A0C (25) r25 (/64): 0x000000008007B000 (26) r26 (/64): 0x000000008007D000 (27) r27 (/64): 0xFFFFFFC000080450 (28) r28 (/64): 0x0000004080000000 (29) r29 (/64): 0xFFFFFFC00087FF20 (30) r30 (/64): 0xFFFFFFC000085114 (31) sp (/64): 0xFFFFFFC00087FF20 (32) pc (/64): 0xFFFFFFC000093528 (33) xPSR (/64): 0x00000000600001C5 And from gdb (gdb) bt #0 cpu_do_idle () at /mnt/host/source/src/third_party/kernel/3.14/arch/arm64/mm/proc.S:87 #1 0xffffffc000085114 in arch_cpu_idle () at /mnt/host/source/src/third_party/kernel/3.14/arch/arm64/kernel/process.c:107 #2 0x0000000000000000 in ??
