Add the riscv64 page to the cluster management guide (UEFI + grub2 boot path, discovery through mknb's grub2 network configurations, stateful and stateless provisioning, the dependency picture for a management node on riscv64, limitations), list riscv64 in the node object attributes and in the support matrices, add the architecture to the cross-build page for stateless images, extend the grub2 install guide (and fix its swapped x86_64/aarch64 file names), the uninstall package lists, the DHCP backend validation matrix and the mknb/genimage man pages, and carry the riscv64 schema values into the generated nodetype, osimage, noderes, node and group references.

grub2 support for x86_64, aarch64 and riscv64
|
|
=============================================
|
|
|
|
xCAT 2.17 enables grub2 boot support for x86_64 and aarch64 but does not ship the necessary grub2 binaries for those architectures.
|
|
If you want to use grub2 for x86_64 or aarch64 you need to download the binaries from some EL OS repository.
|
|
|
|
riscv64 nodes can only boot through UEFI firmware and grub2, so they always need ``grub2.riscv64``. Recent ``grub2-xcat`` packages from xcat-dep install it; if the package on your management node does not (``ls /tftpboot/boot/grub2/grub2.riscv64``), copy the binary by hand as described below.

|
|
|
#. Download files from an BaseOS EL repository mirror
|
|
|
|
For EL these files are named ``grubx64.efi`` (x86_64), ``grubaa64.efi`` (aarch64) and ``grubriscv64.efi`` (riscv64) and usually in ``BaseOS/<arch>/os/EFI/BOOT``.
|
|
For very recent hardware you might need to use a newer grub version. Therefore, it's recommended to use a binary from the latest operationg system release available.
|
|
You can use Red Hat Enterprise Linux, AlmaLinux, Rocky Linux or even Fedora repositories to download the grub files.
|
|
|
|
#. Copy downloaded files to ``/tftpboot/boot/grub2``:
|
|
|
|
* x86_64: ``/tftpboot/boot/grub2/grub2.x86_64``
|
|
* aarch64: ``/tftpboot/boot/grub2/grub2.aarch64``
|
|
* riscv64: ``/tftpboot/boot/grub2/grub2.riscv64``
