2010-06-13hpet: Catch out-of-bounds timer accessJan Kiszka1-1/+5
Also prevent out-of-bounds write access to the timers but don't spam the host console if it triggers. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2010-06-10esp: lower IRQ on soft resetBlue Swirl1-5/+14
42f1ced228c9b616cfa2b69846025271618e4ef5 removed irq lowering during reset. However, for chip reset command and DMA reset signal, its actually the correct thing to do. Lower IRQ on soft reset only. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2010-06-07virtio-net: truncating packetMichael S. Tsirkin1-6/+9
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.

2010-06-02virtio-net: stop vhost backend on vmstopMichael S. Tsirkin1-6/+5
vhost net currently keeps running after vmstop, which causes trouble as qemy does not check for dirty pages anymore. The fix is to simply keep vm and vhost running/stopped status in sync. Tested-by: David L Stevens <dlstevens@us.ibm.com> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2010-06-01Monitor: Drop QMP documentation from codeLuiz Capitulino2-74/+0
Previous commit added QMP documentation to the qemu-monitor.hx file, it's is a copy of this information. While it's good to keep it near code, maintaining two copies of the same information is too hard and has little benefit as we don't expect client writers to consult the code to find how to use a QMP command.

2010-05-31arm: fix arm kernel boot for non zero start addrLars Munch8-29/+1
Booting an arm kernel has been broken a while when booting from non zero start address. This is due to the order of events: board init loads the kernel and sets register 15 to the start address and then qemu_system_reset reset the cpu making register 15 zero again. This patch fixes the usage of the register 15 start address trick in combination with arm_load_kernel. Signed-off-by: Lars Munch <lars@segv.dk> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

On the real hardware (SS-5, LX) the MMU is not padded, but aliased. Software shouldn't use aliased addresses, neither should it crash when it uses (on the real hardware it wouldn't).

2010-05-21arm_timer: fix oneshot modeRabin Vincent1-1/+1
In oneshot mode, the delta needs to come from the TimerLoad register, not the maximum limit. Signed-off-by: Rabin Vincent <rabin@rab.in> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2010-05-21arm_timer: reload timer when enabledRabin Vincent1-1/+1
Reload the timer when TimerControl is written, if the timer is to be enabled. Otherwise, if an earlier write to TimerLoad was done while periodic mode was not set, s->delta may incorrectly still have the value of the maximum limit instead of the value written to TimerLoad. This problem is evident on versatileap on current linux-next, which enables TIMER_CTRL_32BIT before writing to TimerLoad and then enabling periodic mode and starting the timer. This causes the first periodic tick to be scheduled to occur after 0xffffffff periods, leading to a perceived hang while the kernel waits for the first timer tick.

2010-05-21virtio-blk: Avoid zeroing every request structureStefan Hajnoczi1-1/+3
The VirtIOBlockRequest structure is about 40 KB in size. This patch avoids zeroing every request by only initializing fields that are read. The other fields are either written to or may not be used at all. Oprofile shows about 10% of CPU samples in memset called by virtio_blk_alloc_request(). The workload is dd if=/dev/vda of=/dev/null iflag=direct bs=8k running concurrently 4 times. This patch makes memset disappear to the bottom of the profile.
