* [PPC64] Fix GDB sigtramp detectionLeandro Lupori2019-11-011-2/+8
| | | | | | | | | | | | | | Current implementation of ppcfbsd_pc_in_sigtramp() seems to take only 32-bit PowerPC in account, as on 64-bit PowerPC most kernel instruction addresses will be wrongly reported as in sigtramp. This change adds proper sigtramp detection for PPC64. Reviewed by: jhibbits Differential Revision: https://reviews.freebsd.org/D22199 Notes: svn path=/head/; revision=354239

* Fix KGDB backtrace on ARMWojciech Macek2016-04-203-1/+9
| | | | | | | | | | | | | | | | | | | | Modify trapframe decoding to properly analyze trapframe. Provide method for fixup_pc. It happens, that in some kernel functions, the GDB stack frame decoder cannot determine both func name and frame size. This is because these functions either contain invalid instruction, or their format does not match standard schema. Detect that scenarios and move PC accordingly to jump into known function schema, which GDB is able to parse.

* Workaround KGDB issues on ARM by ignoring ARM EABI version higher than 5Zbigniew Bodek2015-10-301-0/+15
| | | | | | | | | | | | | | | | | | | To make KGDB working, it needs to understand kernel ELF image. By default it is compiled using EABI_5, which is not supported on the gdb-6. As a workaround, treat these images as EABI_2 because they share a lot of things in common. This workaround does not guarantee ALL funtionalities to work.

This fixes unwinding over the signal frame after trampoline was moved to the shared page. The code would be more correct if using sysctl for the target process instead of inspecting gdb' own trampoline, but the current change is least intrusive and currently, we always initialize the native ABI sysvec first, which means that trampoline location for FreeBSD/amd64 ABI is relatively stable.

Right now it is just popluated with a thread name. GDB, then, retrieves the correct informations from the corefile via the BFD interface, as it groks the ELF notes and create appropriate pseudo-sections.
