Thanks. It's a bug. We should load all memory addresses to local TCG temps

Do you think we should probe all the memory addresses for the store pair instructions? If
so, can we avoid the use of a helper function?
Depends on what the hardware does.

Sometimes, `ep` is not enforced to 0 when `pid` is `USB_TOKEN_SETUP`. I
trigger this through dwc2

This patch extends virtio-blk emulation to handle zoned device commands
by calling the new block layer APIs to perform zoned device I/O on
behalf of the guest. It supports Report Zone, four zone oparations (open,

Zoned Block Devices (ZBDs) devide the LBA space to block regions called zones
that are larger than the LBA size. It can only allow sequential writes, which
reduces write amplification in SSD, leading to higher throughput and increased
capacity. More details about ZBDs can be found at:
