There is a set of functions ending in ``_swap`` which, if the parameter
is true, returns the value in the endianness that is the reverse of
-the guest native endianness, as determined by ``TARGET_WORDS_BIGENDIAN``.
+the guest native endianness, as determined by ``TARGET_BIG_ENDIAN``.
Function names follow the pattern:
Note: hv-version-id-* are not enlightenments and thus don't enable Hyper-V
identification when specified without any other enlightenments.
+3.21. hv-syndbg
+===============
+Enables Hyper-V synthetic debugger interface, this is a special interface used
+by Windows Kernel debugger to send the packets through, rather than sending
+them via serial/network .
+When enabled, this enlightenment provides additional communication facilities
+to the guest: SynDbg messages.
+This new communication is used by Windows Kernel debugger rather than sending
+packets via serial/network, adding significant performance boost over the other
+comm channels.
+This enlightenment requires a VMBus device (-device vmbus-bridge,irq=15)
+and the follow enlightenments to work:
+hv-relaxed,hv_time,hv-vapic,hv-vpindex,hv-synic,hv-runtime,hv-stimer

+ * a stop in gdb that could be cleared by doing another step.
+ *
+ * Stepping over a POPF/LAHF instruction will let it overwrite the
+ * TF flags, ending the stepping mode.
+ *
+ * 2. Stepping over an instruction raising an exception (e.g. INT, DIV,
+ * or anything that could result in a page fault) will save the flags
+ * to the stack, clear the TF flag, and let the guest execute the
+ * handler. Normally, the guest will restore the original flags,
+ * that will continue single-stepping.
+ *
+ * 3. Debuggers running on the guest may wish to set TF to do instruction
+ * stepping. INT1 events generated by it would be intercepted by us,
+ * as long as the gdb is connected to QEMU.
+ *
+ * In practice this means that:
+ * 1. Stepping through flags-modifying instructions may cause gdb to
+ * continue or stop in unexpected places. This will be fully recoverable
+ * and will not crash the target.
+ *
+ * 2. Stepping over an instruction that triggers an exception will step
+ * over the exception handler, not into it.
+ *
+ * 3. Debugging the guest via gdb, while running debugger on the guest
+ * at the same time may lead to unexpected effects. Removing all
+ * breakpoints set via QEMU will prevent any further interference
+ * with the guest-level debuggers.
+ *
+ * The limitations can be addressed as shown below:
+ * 1. PUSHF/SAHF/POPF/LAHF/IRET instructions can be emulated instead of
+ * stepping through them. The exact semantics of the instructions is
+ * defined in the "Combined Volume Set of Intel 64 and IA-32
+ * Architectures Software Developer's Manuals", however it involves a
+ * fair amount of corner cases due to compatibility with real mode,
+ * virtual 8086 mode, and differences between 64-bit and 32-bit modes.
+ *
+ * 2. We could step into the guest's exception handlers using the following
+ * sequence:
+ * a. Temporarily enable catching of all exception types via
+ * whpx_set_exception_exit_bitmap().
+ * b. Once an exception is intercepted, read the IDT/GDT and locate
+ * the original handler.
+ * c. Patch the original handler, injecting an INT3 at the beginning.
+ * d. Update the exception exit bitmap to only catch the
+ * WHvX64ExceptionTypeBreakpointTrap exception.
+ * e. Let the affected CPU run in the exclusive mode.
+ * f. Restore the original handler and the exception exit bitmap.
+ * Note that handling all corner cases related to IDT/GDT is harder
+ * than it may seem. See x86_cpu_get_phys_page_attrs_debug() for a
+ * rough idea.
+ *
+ * 3. In order to properly support guest-level debugging in parallel with
+ * the QEMU-level debugging, we would need to be able to pass some INT1
+ * events to the guest. This could be done via the following methods:
+ * a. Using the WHvRegisterPendingEvent register. As of Windows 21H1,
+ * it seems to only work for interrupts and not software
+ * exceptions.
+ * b. Locating and patching the original handler by parsing IDT/GDT.
+ * This involves relatively complex logic outlined in the previous
+ * paragraph.
+ * c. Emulating the exception invocation (i.e. manually updating RIP,
+ * RFLAGS, and pushing the old values to stack). This is even more
+ * complicated than the previous option, since it involves checking
+ * CPL, gate attributes, and doing various adjustments depending
+ * on the current CPU mode, whether the CPL is changing, etc.
