Changelog for ROCgdb

Full documentation for ROCgdb is available at docs.amd.com

ROCgdb-16

Added

When opening a core dump, GDB can use the "sysroot" or "solib-search-path" settings to locate files containing GPU code objects. This improves opening GPU code objects on systems different from the one where the core dump was generated.

(Unreleased) ROCgdb-15

Added

'info agents' now prints the agent location as "DDD:BB:DD.F", where "DDDD" is the agent's PCI domain.
Add support for precise ALU exception reporting for architectures that support it. Precise ALU exceptions reporting is controlled with the following commands:
- set amdgpu precise-alu-exceptions
- show amdgpu precise-alu-exceptions

(Unreleased) ROCgdb-14

Added

Introduce the coremerge utility to merge a host core dump and a GPU-only AMDGPU core dump into a unified AMDGPU corefile.
Support for generating and opening core files for heterogeneous processes.

(Unreleased) ROCgdb-13

Added

Support for watchpoints on scratch memory addresses.
Add support for gfx1100, gfx1101, and gfx1102.
Added support for gfx940, gfx941 and gfx942.

Optimized

Improved performances when handling the end of a process with a large number of threads.

Known Issues

On certain configurations, ROCgdb can show the following warning message:

warning: Probes-based dynamic linker interface failed. Reverting to original interface.

This does not affect ROCgdb's functionalities.
ROCgdb cannot debug a program on an AMDGPU device past a s_sendmsg sendmsg(MSG_DEALLOC_VGPRS) instruction. If an exception is reported after this instruction has been executed (including asynchronous exceptions), the wave is killed and the exceptions are only reported by the ROCm runtime.
