-/**
- * QTest Protocol
- *
- * Line based protocol, request/response based. Server can send async messages
- * so clients should always handle many async messages before the response
- * comes in.
- *
- * Valid requests
- *
- * Clock management:
- *
- * The qtest client is completely in charge of the QEMU_CLOCK_VIRTUAL. qtest commands
- * let you adjust the value of the clock (monotonically). All the commands
- * return the current value of the clock in nanoseconds.
- *
- * > clock_step
- * < OK VALUE
- *
- * Advance the clock to the next deadline. Useful when waiting for
- * asynchronous events.
- *
- * > clock_step NS
- * < OK VALUE
- *
- * Advance the clock by NS nanoseconds.
- *
- * > clock_set NS
- * < OK VALUE
- *
- * Advance the clock to NS nanoseconds (do nothing if it's already past).
- *
- * PIO and memory access:
- *
- * > outb ADDR VALUE
- * < OK
- *
- * > outw ADDR VALUE
- * < OK
- *
- * > outl ADDR VALUE
- * < OK
- *
- * > inb ADDR
- * < OK VALUE
- *
- * > inw ADDR
- * < OK VALUE
- *
- * > inl ADDR
- * < OK VALUE
- *
- * > writeb ADDR VALUE
- * < OK
- *
- * > writew ADDR VALUE
- * < OK
- *
- * > writel ADDR VALUE
- * < OK
- *
- * > writeq ADDR VALUE
- * < OK
- *
- * > readb ADDR
- * < OK VALUE
- *
- * > readw ADDR
- * < OK VALUE
- *
- * > readl ADDR
- * < OK VALUE
- *
- * > readq ADDR
- * < OK VALUE
- *
- * > read ADDR SIZE
- * < OK DATA
- *
- * > write ADDR SIZE DATA
- * < OK
- *
- * > b64read ADDR SIZE
- * < OK B64_DATA
- *
- * > b64write ADDR SIZE B64_DATA
- * < OK
- *
- * > memset ADDR SIZE VALUE
- * < OK
- *
- * ADDR, SIZE, VALUE are all integers parsed with strtoul() with a base of 0.
- * For 'memset' a zero size is permitted and does nothing.
- *
- * DATA is an arbitrarily long hex number prefixed with '0x'. If it's smaller
- * than the expected size, the value will be zero filled at the end of the data
- * sequence.
- *
- * B64_DATA is an arbitrarily long base64 encoded string.
- * If the sizes do not match, the data will be truncated.
- *
- * IRQ management:
- *
- * > irq_intercept_in QOM-PATH
- * < OK
- *
- * > irq_intercept_out QOM-PATH
- * < OK
- *
- * Attach to the gpio-in (resp. gpio-out) pins exported by the device at
- * QOM-PATH. When the pin is triggered, one of the following async messages
- * will be printed to the qtest stream:
- *
- * IRQ raise NUM
- * IRQ lower NUM
- *
- * where NUM is an IRQ number. For the PC, interrupts can be intercepted
- * simply with "irq_intercept_in ioapic" (note that IRQ0 comes out with
- * NUM=0 even though it is remapped to GSI 2).
- *
- * Setting interrupt level:
- *
- * > set_irq_in QOM-PATH NAME NUM LEVEL
- * < OK
- *
- * where NAME is the name of the irq/gpio list, NUM is an IRQ number and
- * LEVEL is an signed integer IRQ level.
- *
- * Forcibly set the given interrupt pin to the given level.
- *
