# Changelog for ROCgdb
|
|
|
|
Full documentation for ROCgdb is available at
|
|
[rocm.docs.amd.com/rocgdb](https://rocm.docs.amd.com/projects/ROCgdb/en/latest/index.html)
|
|
|
|
## ROCgdb-X for ROCm-next
|
|
|
|
### Added
|
|
|
|
- Dumping core of AMD GPU programs with the "gcore" command is now
|
|
significantly faster, particularly for kernels that use small
|
|
amounts of VRAM.
|
|
|
|
## ROCgdb-16-3 for ROCm-7.13
|
|
|
|
### Added
|
|
|
|
- Support for the `gfx1153` architecture.
|
|
|
|
## ROCgdb-16-3 for ROCm-7.11
|
|
|
|
### Added
|
|
|
|
- Support for the HIP language and its built-in variables:
|
|
- `threadIdx`
|
|
- `blockIdx`
|
|
- `blockDim`
|
|
- `gridDim`
|
|
- `warpSize`
|
|
|
|
## ROCgdb-16-3 for ROCm-7.2
|
|
|
|
### Added
|
|
|
|
- GDB now determines the name of AMD GPU threads based on the name of
|
|
their kernel function.
|
|
|
|
## ROCgdb-16-3 for ROCm-7.0
|
|
|
|
### Added
|
|
|
|
- Support for the following architectures:
|
|
- `gfx950`
|
|
- `gfx1150`
|
|
- `gfx1151`
|
|
- Support for FP4, FP6 and FP8 micro-scaling (MX) data types with the `gfx950`
|
|
architecture.
|
|
|
|
### Removed
|
|
|
|
- Support for the gfx940 and gfx941 architectures.
|
|
|
|
## ROCgdb-15.2 for ROCm-6.4
|
|
|
|
### Added
|
|
|
|
- Support for debugging shaders compiled for the following generic targets:
|
|
- `gfx9-generic`
|
|
- `gfx9-4-generic`
|
|
- `gfx10-1-generic`
|
|
- `gfx10-3-generic`
|
|
- `gfx11-generic`
|
|
- `gfx12-generic`
|
|
|
|
## ROCgdb-15.2 (for ROCm-6.3)
|
|
|
|
### Added
|
|
|
|
- Support for gfx1200 and gfx1201 architectures.
|
|
- Support for precise ALU exception reporting for supported architectures.
|
|
Precise ALU exceptions reporting is controlled with the following commands:
|
|
- set amdgpu precise-alu-exceptions
|
|
- show amdgpu precise-alu-exceptions
|
|
|
|
### Changed
|
|
|
|
- The `sysroot` or `solib-search-path` settings can now be used to locate files
|
|
containing GPU code objects when opening a core dump. This allows opening
|
|
GPU code objects on systems different from the one where the core dump was
|
|
generated.
|
|
|
|
### Resolved issues
|
|
|
|
- Fixed possible hangs when opening some AMDGPU core dumps in ROCgdb.
|
|
- Addressed cases where the `roccoremerge` utility improperly handled LOAD
|
|
segment copy from the host core dump to the combined core dump.
|
|
|
|
## ROCgdb-14.2 (for ROCm-6.2)
|
|
|
|
### Added
|
|
|
|
- 'info agents' now prints the agent location as "DDD:BB:DD.F", where "DDDD" is
|
|
the agent's PCI domain.
|
|
- 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.
|
|
|
|
## ROCgdb-13.2 (for ROCm-6.0)
|
|
|
|
### Added
|
|
|
|
- Add support for gfx1100, gfx1101, and gfx1102.
|
|
- Added support for gfx940, gfx941 and gfx942.
|
|
|
|
### Known Issues
|
|
|
|
- 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.
|
|
|
|
## ROCgdb-13.2 (for ROCm-5.7)
|
|
|
|
- Support for watchpoints on scratch memory addresses.
|
|
|
|
## ROCgdb-13.1 (for ROCm-5.6)
|
|
|
|
### 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.
