2010-04-11Sparc: fix exceptions in delay slotBlue Swirl
Fix a case where an exception happens with the instruction in the delay slot. Recovery of branch condition in the exception handling code was not converted to TCG. Because the condition was bogus, wrong NPC could be selected from the two candidates. A nice bug report with a test case can be found in: https://bugs.launchpad.net/qemu/+bug/551814 Fix based on patch by Fabrice Bellard. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2010-04-10target-alpha: Use non-inverted arguments to gen_{f}cmov.Richard Henderson

2010-04-10boot: remove unused boot_devices_bitmap variableEduardo Habkost
In addition to removing the variable, this also renames the parse_bootdevices() function to validate_bootdevices(), as we don't need its return value anymore.

2010-04-10net: remove broken net_set_boot_mask() boot device validationEduardo Habkost
There are many problems with net_set_boot_mask(): 1) It is broken when using the device model instead of "-net nic". Example: $ qemu-system-x86_64 -device rtl8139,vlan=0,id=net0,mac=52:54:00:82:41:fd,bus=pci.0,addr=0x4 -net user,vlan=0,name=hostnet0 -vnc 0.0.0.0:0 -boot n Cannot boot from non-existent NIC $ 2) The mask was previously used to set which boot ROMs were supposed to be loaded, but this was changed long time ago. Now all ROM images are loaded, and SeaBIOS takes care of jumping to the right boot entry point depending on the boot settings. 3) Interpretation and validation of the boot parameter letters is done on the machine type code. Examples: PC accepts only a,b,c,d,n as valid boot device letters. mac99 accepts only a,b,c,d,e,f. As a side-effect of this change, qemu-kvm won't abort anymore if using "-boot n" on a machine with no network devices. Checking if the requested boot device is valid is now a task for the BIOS or the machine-type code.

2010-04-10net: remove NICInfo.bootable fieldEduardo Habkost

2010-04-10qcow2: Remove request from in-flight list after errorKevin Wolf
If we complete a request with a failure we need to remove it from the list of requests that are in flight. If we don't do it, the next time the same AIOCB is used for a cluster allocation it will create a loop in the list and qemu will hang in an endless loop.

2010-04-10block: Fix multiwrite memory leak in error caseKevin Wolf
Previously multiwrite_user_cb was never called if a request in the multiwrite batch failed right away because it did set mcb->error immediately. Make it look more like a normal callback to fix this.

2010-04-10block: Fix multiwrite error handlingKevin Wolf
When two requests of the same multiwrite batch fail, the callback of all requests in that batch were called twice.

2010-04-09Implement virtio resetAlexander Graf
The guest may issue a RESET command for virtio. So far we didn't bother to implement it, but with my new bootloader we actually need it for Linux to get back to a safe state. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2010-04-09Always notify consumers of char devices if they're openAlexander Graf
When using virtio-console on s390, the input doesn't work. The root of the problem is rather simple. What happens is the following: 1) create character device for stdio 2) char device is done creating, sends OPENED event 3) virtio-console adds handlers 4) no event comes because the char device is open already 5) virtio-console doesn't accept input because it didn't receive an OPENED event To make that sure virtio-console gets notified that the character device is open even when it's been open from the beginning, this patch introduces a variable that keeps track of the opened state. If the device is open when the event handlers get installed, we just notify the handler. This fixes input with virtio-console on s390.

2010-04-09Avoid page_set_flags() assert in qemu-user host page protection codeJuergen Lock
V2 that uses endaddr = end-of-guest-address-space if !h2g_valid(endaddr) after I found out that indeed works; and also disables the FreeBSD 6.x /compat/linux/proc/self/maps fallback because it can return partial lines if (at least I think that's the reason) the mappings change between subsequent read() calls.

2010-04-08Make virtio-pci building conditional againAlexander Graf
Commit b305b9d7d6990e492966ffb1fdf619482adeb7e2 made building of virtio-pci conditional and not enabled on S390x, because it collides with the S390 bus. Commit 087431d1d1bf4e785edfa89e8cd05fcdac558dc3 accidentially reverted that behavior, breaking S390x again. So here's a follow-up patch disabling building of virtio-pci on S390x again.

Add functions for synthetic operations: addi, mtctl, dep, shd, vshd, ori, andi, shifts, rotates, multiply, branches, setcond.
