[PATCH 0/2] hw/loongarch: Harden boot param

Posted by Bibo Mao 1 month, 3 weeks ago

When booting the Linux kernel without UEFI BIOS, QEMU needs to set the boot param for
kernel. This patch adds memory boundary checking when adding boot param.

Also this patch set adds bootargs and initrd in the FDT table.

Bibo Mao (2):
  hw/loongarch/boot: Check memory boundary in init_boot_rom()
  hw/loongarch/virt: Add bootargs and initrd to device-tree
