Add acpi_rsdp_addr in boot_params to allow crosvm to pass a physicall address of RSDP to the Linux guest kernel, so that the linux guest kernel can parse the constructed ACPI tables and enable the ACPI. Although there is ACPI tables but as we still have "acpi=off" in command line parameter, there is still no ACPI in guest kernel. The ACPI construction refers to the implementation of the Cloud-hypervisor commit: - arch: x86_64: Generate basic ACPI tables BUG=chromium:1018674 TEST=None Change-Id: Ibcb2ae98c43da8ef8c07a07eda9213f61570d14c Signed-off-by: Chuanxiao Dong <chuanxiao.dong@intel.corp-partner.google.com> Reviewed-on: https://chromium-review.googlesource.com/c/chromiumos/platform/crosvm/+/2035351 Reviewed-by: Tomasz Jeznach <tjeznach@chromium.org> Tested-by: kokoro <noreply+kokoro@google.com> Commit-Queue: Tomasz Jeznach <tjeznach@chromium.org> |
