Dear Martin,
Thank you very much for your thoughtful suggestions regarding the PyKdump extension and
its 'scsishow' and 'nvme' commands. I truly appreciate you taking the time
to share these references, which demonstrate your deep expertise in this domain.
Indeed, during our development process, we have found PyKdump to be a valuable resource,
specifically its field selection strategy, data layout logic, and visual presentation
approach for SCSI/NVMe information. The documentation and examples also have been quite
helpful in our work.
However, in certain specialized environments - particularly in completely isolated
internal networks without internet access - we've found that PyKdump can present
challenges for compilation and deployment. This is where we believe our sdinfo extension
offers a distinct advantage, as it can be packaged directly within the crash-utility RPM,
making distribution and deployment significantly simpler in these restricted
environments.
We remain very interested in having sdinfo listed on the Extension Modules page as it
provides a complementary solution that addresses specific deployment scenarios that other
tools might find challenging. The extension is designed with maintenance and compatibility
in mind, and we're committed to keeping it updated alongside crash-utility
developments.
Thank you again for your valuable input and expertise. We're open to further
discussion about how sdinfo might complement the existing ecosystem of crash extensions.
Best regards,
Yao Sang

Dear Crash Utility Maintainers,
I would like to submit a new extension module for inclusion in the Crash Extension Modules page. Below are the required details:
1.Extension Name: sdinfo
2.Command(s): sdinfo
3.Comments
- Functionality: Displays Linux kernel's SCSI disk information, including devices, hosts, targets, and associated I/O requests and SCSI commands. Support for NVMe devices is currently under development and will be added in upcoming releases.
- To build the module from the top-level `crash-<version>` directory, enter:
$ cp <path-to>/scsi.c scsi.mk extensions
$ make extensions
- Package Website: https://github.com/briston-dev/crash-diskutils
- Requires crash-utility version >= 7.2.8
- Author: Yao Sang <sangyao@kylinos.cn>
As specified in the extension guidelines, please add this module to the Crash Extension Modules page. This extension will be actively maintained with regular updates to ensure compatibility with new kernel versions and additional feature enhancements.
Let me know if additional information is needed. Thank you for your consideration!
Best regards,
Yao Sang
