2012-10-30hw/sd.c: Fix erase for high capacity cardsIgor Mitsyanko2-4/+14
Standard capacity cards SDSC use byte unit address while SDHC and SDXC cards use block unit address (512 bytes) when setting ERASE_START and ERASE_END with CMD32 and CMD33, we have to account for this.

Implement byte/halfword read and write for the NVIC SCB_SHPRx (System Handler Priority Registers). Do this by removing SHPR word access from nvic_readl/writel and adding common code to hande all access sizes in nvic_sysreg_read/write. Because the "nvic_state *s" variable now needs to be declared in nvic_sysreg_read/write, the "void *opaque" parameter of nvic_readl/writel is changed to "nvic_state *s".

2012-10-29s390: sclp ascii console supportHeinz Graalfs2-1/+307
This code adds console support by implementing SCLP's ASCII Console Data event. This is the same console as LPARs ASCII console or z/VMs sysascii. The console can be specified manually with something like -chardev stdio,id=charconsole0 -device sclpconsole,chardev=charconsole0,id=console0 Newer kernels will autodetect that console and prefer that over virtio console. When data is received from the character layer it creates a service interrupt to trigger a Read Event Data command from the guest that will pick up the received character byte-stream. When characters are echo'ed by the linux guest a Write Event Data occurs which is forwarded by the Event Facility to the console that supports a corresponding mask value. Console resizing is not supported. The character layer byte-stream is buffered using a fixed size iov buffer.

2012-10-29s390: sclp signal quiesce supportHeinz Graalfs3-0/+131
This implements the sclp signal quiesce event via the SCLP Event Facility. This allows to gracefully shutdown a guest by using system_powerdown notifiers. It creates a service interrupt that will trigger a Read Event Data command from the guest. This code will then add an event that is interpreted by linux guests as ctrl-alt-del.

2012-10-29s390: sclp event supportHeinz Graalfs6-2/+579
Several SCLP features are considered to be events. Those events don't provide SCLP commands on their own, instead they are all based on Read Event Data, Write Event Data, Write Event Mask and the service interrupt. Follow-on patches will provide SCLP's Signal Quiesce (via system_powerdown) and the ASCII console. Further down the road the sclp line mode console and configuration change events (e.g. cpu hotplug) can be implemented.

2012-10-29s390: sclp base supportHeinz Graalfs6-60/+198
This adds a more generic infrastructure for handling Service-Call requests on s390. Currently we only support a small subset of Read SCP Info directly in target-s390x. This patch provides the base infrastructure for supporting more commands and moves Read SCP Info. In the future we could add additional commands for hotplug, call home and event handling.

2012-10-29s390: use sync regs for register transferChristian Borntraeger1-20/+92
Newer kernels provide the guest registers in kvm_run. Lets use those if available (i.e. the capability is set). This avoids ioctls on cpu_synchronize_state making intercepts faster. In addition, we have now the prefix register, the access registers the control registers up to date. This helps in certain cases, e.g. for resolving kernel module addresses with gdb on a guest. On return, we update the registers according to the level statement, i.e. we put all registers for KVM_PUT_FULL_STATE and _RESET_STATE.

2012-10-29s390/kvm_stat: correct sys_perf_event_open syscall numberHeinz Graalfs1-2/+9
Correct sys_perf_event_open syscall number for s390 architecture - the hardcoded syscall number 298 is for x86 but should be different for other architectures. In case we figure out via /proc/cpuinfo that we are running on s390 the appropriate syscall number is used from map syscall_numbers; other architectures can extend this.

2012-10-29virtio-net: enable mrg buf header in tap on linuxMichael S. Tsirkin2-21/+18
