A problem internal to GDB has been detected, Before diving into why this error appears, let's explore how things are expected to work in normal circumstances. When a process being debugged starts using the ROCm runtime, the following happens: - The runtime registers itself to the driver. - The driver creates a "runtime loaded" event and notifies the debugger that a new event is available by writing to a file descriptor which is registered in GDB's main event loop. - GDB core calls the callback associated with this file descriptor (dbgapi_notifier_handler). Because the amd-dbgapi-target is not pushed at this point, the handler pulls the "runtime loaded" event from the driver (this is the only event which can be available at this point) and eventually pushes the amd-dbgapi-target on the inferior's target stack. In a nutshell, this is the expected AMDGPU runtime activation process. From there, when new events are available regarding the GPU threads, the same file descriptor is written to. The callback sees that the amd-dbgapi-target is pushed so marks the amd_dbgapi_async_event_handler. This will later cause amd_dbgapi_target::wait to be called. The wait method pulls all the available events from the driver and handles them. The wait method returns the information conveyed by the first event, the other events are cached for later calls of the wait method. Note that because we are under the wait method, we know that the amd-dbgapi-target is pushed on the inferior target stack. This implies that the runtime activation event has been seen already. As a consequence, we cannot receive another event indicating that the runtime gets activated. This is what the failing assertion checks. In the case when we have multiple inferiors however, there is a flaw in what have been described above. If one inferior (let's call it inferior 1) already has the amd-dbgapi-target pushed to its target stack and another inferior (inferior 2) activates the ROCm runtime, here is what can happen: - The driver creates the runtime activation for inferior 2 and writes to the associated file descriptor. - GDB has inferior 1 selected and calls target_wait for some reason. - This prompts amd_dbgapi_target::wait to be called. The method pulls all events from the driver, including the runtime activation event for inferior 2, leading to the assertion failure. The fix for this problem is simple. To avoid such problem, we need to make sure that amd_dbgapi_target::wait only pulls events for the current inferior from the driver. This is what this patch implements. This patch also includes a testcase which could fail before this patch. This patch has been tested on a system with multiple GPUs which had more chances to reproduce the original bug. It has also been tested on top of the downstream ROCgdb port which has more AMDGPU related tests. The testcase has been tested with `make check check-read1 check-readmore`.

Lancelot Six	38797d2e73	gdb/testsuite/rocm: Add the hip_devices_support_debug_multi_process proc It is not possible to debug multiple processes simultaneously on all generations of AMDGPU devices. As some tests will need to debug multiple inferiors using AMDGPU devices, we need to ensure that all devices available have the required capability. Failing to do so would result in GDB not being able to debug all inferiors properly. Add the hip_devices_support_debug_multi_process helper function used to ensure that all devices available can debug multiple processes. Approved-By: Pedro Alves <pedro@palves.net>	3 years ago

Tom Tromey	30c01bb104	Restore previous sigmask in gdb.block_signals Tom de Vries found a bug where, sometimes, a SIGCHLD would be delivered to a non-main thread, wreaking havoc. The problem is that gdb.block_signals after first blocking a set of signals, then unblocked the same set rather than restoring the initial situation. This function being called from the DAP thread lead to SIGCHLD being unblocked there. This patch fixes the problem by restoring the previous set of signals instead.

Jose E. Marchesi	1e18ffc991	bpf: include, bfd, opcodes: add EF_BPF_CPUVER ELF header flags This patch adds support for EF_BPF_CPUVER bits in the ELF machine-dependent header flags. These bits encode the BPF CPU version for which the object file has been compiled for. The BPF assembler is updated so it annotates the object files it generates with these bits. The BPF disassembler is updated so it honors EF_BPF_CPUVER to use the appropriate ISA version if the user didn't specify an explicit ISA version in the command line. Note that a value of zero in EF_BPF_CPUVER is interpreted by the disassembler as "use the later supported version" (the BPF CPU versions start with v1.) The readelf utility is updated to pretty print EF_BPF_CPUVER when it prints out the ELF header: $ readelf -h a.out ELF Header: ...

Tom Tromey	0c8a0b88d1	Re-acquire GIL earlier in gdbpy_parse_and_eval Tom de Vries filed a bug about an intermittent gdb DAP failure -- and coincidentally, at the same time, Alexandra Hájková sent email about a somewhat similar failure. After looking into this for a while (with no results) using ASan and valgrind, I found that setting PYTHONMALLOC=malloc_debug found the bug instantly. The problem is that gdbpy_parse_and_eval releases the GIL while calling parse_and_eval, but fails to re-acquire it before calling value_to_value_object. This is easily fixed by introducing a new scope. I wonder whether the test suite should unconditionally set PYTHONMALLOC=malloc_debug.

YunQiang Su	29c108c961	MIPS: Support `-gnuabi64' target triplet suffix for 64-bit Linux targets Make the n64 ABI the default for 64-bit Linux targets specified with `-gnuabi64' suffix included in the target triplet, for configurations such as the Debian mips64el and mips64r6el ports. Adjust testsuite configuration accordingly. There are the following regressions with the new target triplet: mips64-linux-gnuabi64 +FAIL: readelf -S bintest mips64-linux-gnuabi64 +FAIL: MIPS reloc estimation 1 mips64el-linux-gnuabi64 +FAIL: readelf -S bintest mips64el-linux-gnuabi64 +FAIL: MIPS reloc estimation 1 The `readelf' issue comes from a difference in section headers produced that the `binutils/testsuite/binutils-all/readelf.s-64' pattern template does not match. While there has been a precedent it does not appear to me that there is a clear advantage from adding more and more variations to the template rather than forking the existing template into multiple ones for a more exact match. So this is best deferred to a separate discussion. The MIPS reloc estimation issue is an actual bug in `objdump', which discards a number of trailing entries from output here for n64 composed relocations: DYNAMIC RELOCATION RECORDS OFFSET TYPE VALUE 0000000000000000 R_MIPS_NONE ABS 0000000000000000 R_MIPS_NONE ABS and consequently `ld/testsuite/ld-mips-elf/reloc-estimate-1.d' does not match even though ELF output produced is correct according to `readelf': Relocation section '.rel.dyn' at offset 0x10400 contains 2 entries: Offset Info Type Sym.

However, since the empty line is in target-delegates.c (a generated file), there's nothing the author can do about it. To avoid this comment coming up again in the future, change make-target-delegates.py to avoid the trailing empty line. Do this by making it output empty lines before each entity, not after.
