2011-07-29multiboot: Fix bss segment supportGöran Weinholt
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.

2011-07-29Fix last sector write on sd cardDr. David Alan Gilbert

2011-07-29showing a splash picture when startwayne
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: Wayne Xia <xiawenc@linux.vnet.ibm.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

Old version looks like this in info qtree (last four lines): dev: virtconsole, id "" dev-prop: is_console = 1 dev-prop: nr = 0 dev-prop: chardev = <null> dev-prop: name = <null> dev-prop-int: id: 0 dev-prop-int: guest_connected: 1 dev-prop-int: host_connected: 0 dev-prop-int: throttled: 0 Indentation is off, and "dev-prop-int" suggests these are properties you can configure with -device, which isn't the case. The other buses' print_dev() callbacks don't do that. For instance, PCI's output looks like this: class Ethernet controller, addr 00:03.0, pci id 1af4:1000 (sub 1af4:0001) bar 0: i/o at 0xffffffffffffffff [0x1e] bar 1: mem at 0xffffffffffffffff [0xffe] bar 6: mem at 0xffffffffffffffff [0xfffe] Change virtser_bus_dev_print() to that style.

2011-07-23report serial devices created with -device in the PIIX4 config spacePaolo Bonzini
Serial and parallel devices created with -device are not reported in the PIIX4 configuration space, and are hence not picked up by the DSDT. This upsets Windows, which hides them altogether from the guest. To avoid this, check at the end of machine initialization whether the corresponding I/O ports have been registered. The new function in ioport.c does this; this also requires a tweak to isa_unassign_ioport. I left the comment in piix4_pm_initfn since the registers I moved do seem to match the 82371AB datasheet. There are some quirks though. We are setting this bit: "Device 8 EIO Enable (EIO_EN_DEV8)—R/W. 1=Enable PCI access to the device 8 enabled I/O ranges to be claimed by PIIX4 and forwarded to the ISA/EIO bus. 0=Disable. The LPT_MON_EN must be set to enable the decode." but not LPT_MON_EN (bit 18 at 50h): LPT Port Enable (LPT_MON_EN)—R/W. 1=Enable accesses to parallel port address range (LPT_DEC_SEL) to generate a device 8 (parallel port) decode event. 0=Disable. We're also setting the LPT_DEC_SEL field (that's the 0x60 written to 63h) to 11, which means reserved, rather than to 01 (378h-37Fh). Likewise we're not setting SA_MON_EN, SB_MON_EN (respectively bit 14 and bit 16 at address 50h) for the serial ports. However, we're setting COMA_DEC_SEL and COMB_DEC_SEL correctly, unlike the corresponding register for the parallel port. All these fields are left as they are, since they are probably only meant to be used in the DSDT.

2011-07-23net: Consistently use qemu_macaddr_default_if_unsetJan Kiszka
Drop the open-coded MAC assignment from net_init_nic and replace it with standard qemu_macaddr_default_if_unset which is also used by qdev. That avoid creating colliding MACs when instantiating NICs via different mechanisms. This change requires to store the MAC as MACAddr in NICInfo, and the remaining nd_table users need to be updated.
