If you are available, could you kindly take some time to review the patch? If you would like to test the patch set using a RISC-V vmcore on a Linux machine (x86-based), there is another useful option. You can refer to the RISC-V-based vmcore and vmlinux files that I extracted. They are available at the following Google Drive link: Google Drive link: https://drive.google.com/drive/u/1/folders/1iM3la4hQdvSsd-LeOyVZCyoPOnrXvpgo BR, Austin Kim -- Crash-utility mailing list -- [email protected] To unsubscribe send an email to [email protected] https://${domain_name}/admin/lists/devel.lists.crash-utility.osci.io/ Contribution Guidelines: https://github.com/crash-utility/crash/wiki
