Add bdrv_find_overlay(), and bdrv_drop_intermediate(). bdrv_find_overlay(): given 'bs' and the active (topmost) BDS of an image chain, find the image that is the immediate top of 'bs' bdrv_drop_intermediate(): Given 3 BDS (active, top, base), drop images above base up to and including top, and set base to be the backing file of top's overlay node. E.g., this converts: bottom <- base <- intermediate <- top <- active to bottom <- base <- active Signed-off-by: NJeff Cody <jcody@redhat.com> Reviewed-by: NEric Blake <eblake@redhat.com> Signed-off-by: NKevin Wolf <kwolf@redhat.com>

This patch adds gluster as the new block backend in QEMU. This gives QEMU the ability to boot VM images from gluster volumes. Its already possible to boot from VM images on gluster volumes using FUSE mount, but this patchset provides the ability to boot VM images from gluster volumes by by-passing the FUSE layer in gluster. This is made possible by using libgfapi routines to perform IO on gluster volumes directly. VM Image on gluster volume is specified like this: file=gluster[+transport]://[server[:port]]/volname/image[?socket=...] 'gluster' is the protocol. 'transport' specifies the transport type used to connect to gluster management daemon (glusterd). Valid transport types are tcp, unix and rdma. If a transport type isn't specified, then tcp type is assumed. 'server' specifies the server where the volume file specification for the given volume resides. This can be either hostname, ipv4 address or ipv6 address. ipv6 address needs to be within square brackets [ ]. If transport type is 'unix', then 'server' field should not be specifed. The 'socket' field needs to be populated with the path to unix domain socket. 'port' is the port number on which glusterd is listening. This is optional and if not specified, QEMU will send 0 which will make gluster to use the default port. If the transport type is unix, then 'port' should not be specified. 'volname' is the name of the gluster volume which contains the VM image. 'image' is the path to the actual VM image that resides on gluster volume. Examples: file=gluster://1.2.3.4/testvol/a.img file=gluster+tcp://1.2.3.4/testvol/a.img file=gluster+tcp://1.2.3.4:24007/testvol/dir/a.img file=gluster+tcp://[1:2:3:4:5:6:7:8]/testvol/dir/a.img file=gluster+tcp://[1:2:3:4:5:6:7:8]:24007/testvol/dir/a.img file=gluster+tcp://server.domain.com:24007/testvol/dir/a.img file=gluster+unix:///testvol/dir/a.img?socket=/tmp/glusterd.socket file=gluster+rdma://1.2.3.4:24007/testvol/a.imgSigned-off-by: NBharata B Rao <bharata@linux.vnet.ibm.com> Signed-off-by: NKevin Wolf <kwolf@redhat.com>

Currently, after a live snapshot of a drive, the image that has been 'demoted' to be below the new active layer remains r/w. This patch reopens it read-only. Note that we do not check for error on the reopen(), because we will not abort the snapshots if the reopen fails. This patch depends on the bdrv_reopen() series.

In the A series memory map (implemented in the Cortex A15 CoreTile), the first NOR flash bank (flash 0) is mapped to address 0x08000000, while address 0x00000000 can be configured as alias to either the first or the second flash bank.

When setting up the NVIC memory regions the memory range 0x100..0xcff is aliased to an IO memory region that belongs to the ARM GIC. This aliased region should be added to the NVIC memory container, but the actual GIC IO memory region was being added instead. This mixup was causing the wrong IO memory access functions to be called when accessing parts of the NVIC memory.

Added an option to let qemu transfer a configuration file to bios, "etc/boot-fail-wait", which could be specified by command -boot reboot-timeout=T T have a max value of 0xffff, unit is ms. With this option, guest will wait for a given time if not find bootabled device, then reboot. If reboot-timeout is '-1', guest will not reboot, qemu passes '-1' to bios by default. This feature need the new seabios's support. Seabios pulls the value from the fwcfg "file" interface, this interface is used because SeaBIOS needs a reliable way of obtaining a name, value size, and value. It in no way requires that there be a real file on the user's host machine. Signed-off-by: NAmos Kong <akong@redhat.com> Signed-off-by: NAnthony Liguori <aliguori@us.ibm.com>

This is common on desktop setups that often have ipv6 configured but not actually working.

This patch adds a "use64" property which will make the ivshmem driver register a 64bit memory bar when set, so you have something to play with when testing 64bit pci bits.
