2010-06-09target-mips: add microMIPS exception handler supportNathan Froyd
Unlike MIPS16, microMIPS lets you choose the ISA mode for your exception handlers. The ISA mode is selectable via a user-writable CP0.Config3 flag. Signed-off-by: Nathan Froyd <froydnj@codesourcery.com> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2010-06-09target-mips: microMIPS ASE supportNathan Froyd
Add instruction decoding for the microMIPS ASE. All we do is decode and then forward to the existing gen_* routines. Signed-off-by: Nathan Froyd <froydnj@codesourcery.com> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2010-06-09target-mips: mips16 cleanupsNathan Froyd
Change code handling mips16-specific branches to use ISA-neutral special opcodes. Since there are several places where the delay slot requirements for microMIPS branches differ from mips16 branches, using opcodes is easier than checking hflags, then checking mips16 vs. microMIPS.

2010-06-09target-mips: define constants for magic numbersNathan Froyd
Add FMT_* constants for the floating-point format field in opcodes and tweak a few places to use them. Add enums for various invocations of FOP and tweak gen_farith and its lone caller accordingly.

2010-06-09Fix multiboot compilationAlexander Graf
Commit dd4239d6574ca41c94fc0d0f77ddc728510ffc57 broke multiboot. It replaced the instruction "rep insb (%dx), %es:(%edi)" by the binary output of "addr32 rep insb (%dx), %es:(%di)". Linuxboot calls the respective helper function in a code16 section. So the original instruction was automatically translated to its "addr32" equivalent. For multiboot, we're running in code32 so gcc didn't add the "addr32" which breaks the instruction. This patch splits that helper function in one which uses addr32 and one which does not, so everyone's happy. The good news is that nobody probably cared so far. The bundled multiboot.bin binary was built before the change and is thus correct. Please also put this patch into -stable.

2010-06-09net: Fix hotplug with pci_addAmit Shah
The correct model type wasn't getting added when hotplugging nics with pci_add. Testcase: start VM with default nic type. In the qemu_monitor: (qemu) pci_add auto nic model=virtio This results in a nic hot-plug of the same nic type as the default. This was broken in 5294e2c774f120e10b44652ac143abda356f44eb Also changes the behaviour where no .init is defined for a net_client_type. Previously, 0 was returned, which indicated the init was successful and that 0 was the index into the nd_tables[] array. Return -1, indicating unsuccessful init, in such a case.

2010-06-09tcg: Add TYPE parameter to tcg_out_mov.Richard Henderson
Mirror tcg_out_movi in having a TYPE parameter. This allows x86_64 to perform the move at the proper width, which may elide a REX prefix. Introduce a TCG_TYPE_REG enumerator to represent the "native width" of the host register, and to distinguish the usage from "pointer data" as represented by the existing TCG_TYPE_PTR. Update all targets to match. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

virtio net attempts to peek into virtio queue to determine that we have enough space for the complete packet to fit. However, it fails to account for space consumed by virtio net header when it does this, under stress this results in a failure with the message 'truncating packet'. redhat bz 591494.

2010-06-04block: Fix serial number assignmentLuiz Capitulino
We should use 'dinfo->serial' length, 'serial' is a pointer, so the serial number length is currently limited to the pointer size.

2010-06-04block: call the snapshot handlers of the protocol driversMORITA Kazutaka
When snapshot handlers are not defined in the format driver, it is better to call the ones of the protocol driver. This enables us to implement snapshot support in the protocol driver. We need to call bdrv_close() and bdrv_open() handlers of the format driver before and after bdrv_snapshot_goto() call of the protocol. It is because the contents of the block driver state may need to be changed after loading vmstate.

2010-06-04close all the block drivers before the qemu process exitsMORITA Kazutaka
This patch calls the close handler of the block driver before the qemu process exits. This is necessary because the sheepdog block driver releases the lock of VM images in the close handler. Signed-off-by: MORITA Kazutaka <morita.kazutaka@lab.ntt.co.jp> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2010-06-04block: Assume raw for drives without mediaKevin Wolf
qemu -cdrom /dev/cdrom with an empty CD-ROM drive doesn't work any more because we try to guess the format and when this fails (because there is no medium) we exit with an error message. This patch should restore the old behaviour by assuming raw format for such drives. Signed-off-by: Kevin Wolf <kwolf@redhat.com>

2010-06-04qdev: Don't leak string property value on hot unplugMarkus Armbruster
parse_string() qemu_strdup()s the property value. It is never freed. It needs to be freed along with the device. Otherwise, the value of scsi-disk property "ver" gets leaked when hot-unplugging the disk, for instance. Call new PropertyInfo method free() from qdev_free(). Implement it for qdev_prop_string.

2010-06-04ide: Remove redundant IDEState member confMarkus Armbruster
Commit 428c149b added IDEState member conf to let commit 0009baf1 find the BlockConf from there. It exists only for qdev drives, created via ide_drive_initfn(), not for drives created via ide_init2(). But for a qdev drive, we can just as well reach its IDEDevice, which contains the BlockConf. Do that, and revert the parts of commit 428c149b that add IDEState member conf. Signed-off-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
