Public bug reported: SBI SRST extension is needed for handling sifive unmatched reboot and with the reset now merged into openSBI package, enabling SRST extension finally gives us the possibility to reset the board.
The patch to enable SRST extension can be found here: https://lore.kernel.org/all/20210609121322.3058-2-anup.pa...@wdc.com/ or use the attached patch. I tested it on top of 5.13.0-1006.6+22.04.1 on the unmatched board and it allows to successfully reboots the board. ** Affects: linux-riscv (Ubuntu) Importance: Undecided Status: New ** Attachment added: "0001-RISC-V-Use-SBI-SRST-extension-when-available.patch" https://bugs.launchpad.net/bugs/1955042/+attachment/5548032/+files/0001-RISC-V-Use-SBI-SRST-extension-when-available.patch -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1955042 Title: SBI SRST extension is missing To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-riscv/+bug/1955042/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
