Use of the malloc/free/realloc/calloc/valloc/memalign/posix_memalign
APIs is not allowed in the QEMU codebase. Instead of these routines,
use the GLib memory allocation routines g_malloc/g_malloc0/g_new/
-g_new0/g_realloc/g_free or QEMU's qemu_vmalloc/qemu_memalign/qemu_vfree
+g_new0/g_realloc/g_free or QEMU's qemu_memalign/qemu_blockalign/qemu_vfree
APIs.
Please note that g_malloc will exit on allocation failure, so there
is no need to test for failure (as you would have to with malloc).
Calling g_malloc with a zero size is valid and will return NULL.
-Memory allocated by qemu_vmalloc or qemu_memalign must be freed with
-qemu_vfree, since breaking this will cause problems on Win32 and user
-emulators.

-The root of the tree is memory as seen from the CPU's viewpoint (the system
-bus). Nodes in the tree represent other buses, memory controllers, and
-memory regions that have been rerouted. Leaves are RAM and MMIO regions.
+Memory is modelled as an acyclic graph of MemoryRegion objects. Sinks
+(leaves) are RAM and MMIO regions, while other nodes represent

+ * phase II (1bc39ac5d and later, but before e3e92a7be6) kernels

+ * work only for every fourth PCI card, and only if (like old
+ * QEMU) the PCI host device is at slot 0 rather than where
+ * the h/w actually puts it
+ * phase III (e3e92a7be6 and later) kernels still swizzle IRQs between
+ * slots wrongly, but add a fixed offset of 64 to everything
+ * they write to PCI_INTERRUPT_LINE.
+ *
+ * We live in hope of a mythical phase IV kernel which might
+ * actually behave in ways that work on the hardware. Such a
+ * kernel should probably start off by writing some value neither
+ * 27 nor 91 to slot zero's PCI_INTERRUPT_LINE register to
+ * disable the autodetection. After that it can do what it likes.

SMP is supported with up to 255 CPUs.
-Note that adlib, gus and cs4231a are only available when QEMU was

QEMU uses the PC BIOS from the Bochs project and the Plex86/Bochs LGPL
VGA BIOS.
