It's already allowed by the example; there are about 1800 instances in the tree; and disallowing it would lead to if (a) { ... } else { if (b) { ... } else { if (c) { ... } else { if (d) { ... } else { ... } } } } instead of if (a) { ... } else if (b) { ... } else if (c) { ... } else if (d) { ... } else { ... } which is more readable.

Multiboot images can specify a bss segment. The boot loader must clear the memory of the bss and ensure that no modules or structures are allocated inside it. Several fields are provided in the Multiboot header that were previously not used properly. The header is now used to determine how much data should be read from the image and how much memory should be reserved to the bss segment.

Most definitions in softfloat.h are really target-independent, but the file is not because it includes definitions of the default NaN values. Change those to variables to allow including softfloat.h from files that are not compiled per-target. By making them const, the compiler is allowed to optimize them into softfloat functions that use them.

Added options to let qemu transfer two configuration files to bios: "bootsplash.bmp" and "etc/boot-menu-wait", which could be specified by command -boot splash=P,splash-time=T P is jpg/bmp file name or an absolute path, T have a max value of 0xffff, unit is ms. With these two options, if user invoke qemu with menu=on option, then a splash picture would be showed in a given time. For example: qemu -boot menu=on,splash=/root/boot.bmp,splash-time=5000 would make boot.bmp shown as a brand with 5 seconds in the booting up process. This feature need the new seabios's support, which could be got from git. Signed-off-by: NWayne Xia <xiawenc@linux.vnet.ibm.com> Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com>

Instead of adding and deleting regions in one pass, do a delete pass followed by an add pass. This fixes the following case: from: 0x0000-0x0fff ram (a1) 0x1000-0x1fff mmio (a2) 0x2000-0x2fff ram (a3) to: 0x0000-0x2fff ram (b1) The single pass algorithm removed a1, added b2, then removed a2 and a3, which caused the wrong memory map to be built. The two pass algorithm removes a1, a2, and a3, then adds b1. Signed-off-by: NAvi Kivity <avi@redhat.com> Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com>

For non-RAM memory regions, we cannot tell whether this is an I/O region or an MMIO region. Since the qemu backing registration is different for the two, we have to defer initialization until we know which address space we are in. These shenanigans will be removed once the backing registration is unified with the memory API. Signed-off-by: NAvi Kivity <avi@redhat.com> Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com>

get_system_memory() provides the root of the memory hierarchy. This interface is intended to be private between memory.c and exec.c. If this file is included elsewhere, it should be regarded as a bug (or TODO item). However, it will be temporarily needed for the conversion to hierarchical memory routing.

The memory API separates the attributes of a memory region (its size, how reads or writes are handled, dirty logging, and coalescing) from where it is mapped and whether it is enabled. This allows a device to configure a memory region once, then hand it off to its parent bus to map it according to the bus configuration. Hierarchical registration also allows a device to compose a region out of a number of sub-regions with different properties; for example some may be RAM while others may be MMIO.
