Since ARM was not supported by ACPI before version 5.0, it makes sense to lift this restriction. This is not crucial for mach-virt, which is guaranteed to have some memory available below the 4 GB mark, but it is a nice to have for QEMU machines that do not have any 32-bit addressable memory, which is not uncommon for real world 64-bit ARM systems. Since we already emit a version of the RSDP root pointer that has a secondary 64-bit wide address field for the 64-bit root table (XSDT), all we need to do is replace the RSDT generation with the generation of an XSDT table, and use a different slot in the FADT table to refer to the DSDT.

(one queue pair works well). Because there exist some bugs in qemu code when introducing VHOST_USER_PROTOCOL_F_REPLY_ACK to qemu. When vhost_user_set_mem_table is invoked to deal with the vhost message VHOST_USER_SET_MEM_TABLE for the second time, qemu indeed doesn't send the messge (The message needs to be sent only once)but still will be waiting for dpdk's reply ack, then, qemu is always freezing, while DPDK is always waiting for next vhost message from qemu. The patch aims to fix the bug, MQ can work well. The same bug is found in function vhost_user_net_set_mtu, it is fixed at the same time. DPDK related patch is as following: http://www.dpdk.org/dev/patchwork/patch/23955/ Signed-off-by: Zhiyong Yang Cc: qemu-stable@nongnu.org Fixes: ca525ce5618b ("vhost-user: Introduce a new protocol feature REPLY_AC= K.")
