[PATCH v1 0/6] Support booting bios and kernel for LoongArch

Posted by Xiaojuan Yang 3 years, 7 months ago

This series add some new funcitons for LoongArch virt machine.
Support loading uefi bios and linux kernel to boot system, and 
add fw_cfg table, smbios table, acpi table, fdt table to transmit
information for the system.

We could get the uefi bios and linux kernel file by this address:
The kernel file:
   * https://github.com/loongson/linux/tree/loongarch-next
The bios file:
   * https://github.com/loongson/edk2
   * https://github.com/loongson/edk2-platforms

Xiaojuan Yang (6):
  hw/loongarch: Add fw_cfg table support
  hw/loongarch: Add uefi bios loading support
  hw/loongarch: Add linux kernel booting support
  hw/loongarch: Add smbios support
  hw/loongarch: Add acpi ged support
  hw/loongarch: Add fdt support

Queued.

If there are bugs in the smbios or acpi patches, they can be fixed before hard freeze, but 
we do want the feature committed before soft freeze.

Patch 3 has a 32-bit error wrt %lx and uint64_t.

Patch 5 misses setting TARGET_NEED_FDT in configs/targets/loongarch64-softmmu.mak.
