2012-09-25ivshmem: add 64bit optionGerd Hoffmann
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. It also allows to have quite big shared memory regions, like this: [root@fedora ~]# lspci -vs1:1 01:01.0 RAM memory: Red Hat, Inc Device 1110 Subsystem: Red Hat, Inc Device 1100 Physical Slot: 1-1 Flags: fast devsel Memory at fd400000 (32-bit, non-prefetchable) [disabled] [size=256] Memory at 8040000000 (64-bit, prefetchable) [size=1G] [ v5: rebase, update compat property for post-1.2 merge ] [ v4: rebase & adapt to latest master again ] [ v3: rebase & adapt to latest master ] [ v2: default to on as suggested by avi, turn off for pc-$old using compat property ] Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Tested-by: Cam Macdonell <cam@cs.ualberta.ca> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

Report from smatch: lm4549.c:234 lm4549_write_samples(14) error: buffer overflow 's->buffer' 1024 <= 1024 There must be enough space to add two entries starting with index s->buffer_level, therefore the old check was wrong. [Peter Maydell <peter.maydell@linaro.org> clarifies the nature of the analyser warning: I don't object to making the change to placate the analyser, but I don't think this is actually a buffer overrun.

2012-09-21SCSI: Standard INQUIRY data should report HiSup flag as set.Ronnie Sahlberg
QEMU as far as I know only reports LUN numbers using the modes that are described in SAM4. As such, since all LUN numbers generated by the SCSI emulation in QEMU follow SAM4, we should set the HiSup bit in the standard INQUIRY data to indicate such. From SAM4: 4.6.3 LUNs overview All LUN formats described in this standard are hierarchical in structure even when only a single level in that hierarchy is used. The HISUP bit shall be set to one in the standard INQUIRY data (see SPC-4) when any LUN format described in this standard is used. Non-hierarchical formats are outside the scope of this standard.

2012-09-14eepro100: Fix network hang when rx buffers run outBo Yang
This is reported by QA. When installing os with pxe, after the initial kernel and initrd are loaded, the procedure tries to copy files from install server to local harddisk, the network becomes stall because of running out of receive descriptor. [Whitespace fixes and removed qemu_notify_event() because Paolo's earlier net patches have moved it into qemu_flush_queued_packets(). Additional info: I can reproduce the network hang with a tap device doing a iPXE HTTP boot as follows: $ qemu -enable-kvm -m 1024 \ -netdev tap,id=netdev0,script=no,downscript=no \ -device i82559er,netdev=netdev0,romfile=80861209.rom \ -drive if=virtio,cache=none,file=test.img iPXE> ifopen net0 iPXE> config # set static network configuration iPXE> kernel http://mirror.bytemark.co.uk/fedora/linux/releases/17/Fedora/x86_64/os/images/pxeboot/vmlinuz I needed a vanilla iPXE ROM to get to the iPXE prompt. I think the boot prompt has been disabled in the ROMs that ship with QEMU to reduce boot time. During the vmlinuz HTTP download there is a network hang. hw/eepro100.c has reached the end of the rx descriptor list. When the iPXE driver replenishes the rx descriptor list we don't kick the QEMU net subsystem and event loop, thereby leaving the tap netdev without its file descriptor in select(2).

2012-09-14net: notify iothread after flushing queuePaolo Bonzini
virtio-net has code to flush the queue and notify the iothread whenever new receive buffers are added by the guest. That is fine, and indeed we need to do the same in all other drivers. However, notifying the iothread should be work for the network subsystem. And since we are at it we can add a little smartness: if some of the queued packets already could not be delivered, there is no need to notify the iothread.

Commit 93bfef4c6e4b23caea9d51e1099d06433d8835a4 makes qemu-devices which report the qemu version string to the guest in some way use a qemu_get_version function which reports a machine-specific version string. However usb-redir does not expose the qemu version to the guest, only to the usbredir-host as part of the initial handshake. This can then be logged on the usbredir-host side for debugging purposes and is otherwise completely unused! For debugging purposes it is important to have the real qemu version in there, rather then the machine-specific version.
