2011-07-29showing a splash picture when startwayne5-4/+199
Added options to let qemu transfer two configuration files to bios: "bootsplash.bmp" and "etc/boot-menu-wait", which could be specified by command -boot splash=P,splash-time=T P is jpg/bmp file name or an absolute path, T have a max value of 0xffff, unit is ms. With these two options, if user invoke qemu with menu=on option, then a splash picture would be showed in a given time. For example: qemu -boot menu=on,splash=/root/boot.bmp,splash-time=5000 would make boot.bmp shown as a brand with 5 seconds in the booting up process. This feature need the new seabios's support, which could be got from git. Signed-off-by: Wayne Xia <xiawenc@linux.vnet.ibm.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2011-07-29memory: separate building the final memory map into two stepsAvi Kivity1-9/+29
Instead of adding and deleting regions in one pass, do a delete pass followed by an add pass. This fixes the following case: from: 0x0000-0x0fff ram (a1) 0x1000-0x1fff mmio (a2) 0x2000-0x2fff ram (a3) to: 0x0000-0x2fff ram (b1) The single pass algorithm removed a1, added b2, then removed a2 and a3, which caused the wrong memory map to be built. The two pass algorithm removes a1, a2, and a3, then adds b1. Signed-off-by: Avi Kivity <avi@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

For non-RAM memory regions, we cannot tell whether this is an I/O region or an MMIO region.

2011-07-29Hierarchical memory region APIAvi Kivity3-0/+1039
The memory API separates the attributes of a memory region (its size, how reads or writes are handled, dirty logging, and coalescing) from where it is mapped and whether it is enabled. This allows a device to configure a memory region once, then hand it off to its parent bus to map it according to the bus configuration. Hierarchical registration also allows a device to compose a region out of a number of sub-regions with different properties; for example some may be RAM while others may be MMIO.

2011-07-23Register Linux dyntick timer as per-thread signalJan Kiszka3-0/+20
Derived from kvm-tool patch http://thread.gmane.org/gmane.comp.emulators.kvm.devel/74309 Ingo Molnar pointed out that sending the timer signal to the whole process, just blocking it everywhere, is suboptimal with an increasing number of threads. QEMU is also using this pattern so far. Linux provides a (non-portable) way to restrict the signal to a single thread: We can use SIGEV_THREAD_ID unless we are forced to emulate signalfd via an additional thread. That case could theoretically be optimized as well, but it doesn't look worth bothering.

2011-07-23qemu-timer: Introduce clock reset notifierJan Kiszka2-1/+33
QEMU_CLOCK_HOST is based on the system time which may jump backward in case the admin or NTP adjusts it. RTC emulations and other device models can suffer in this case as timers will stall for the period the clock was tuned back. This adds a detection mechanism that checks on every host clock readout if the new time is before the last result. If that is the case a notifier list is informed. Device models interested in this event can register a notifier with the clock. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

Allow client connections for VNC and socket based character devices to be passed in over the monitor using SCM_RIGHTS. One intended usage scenario is to start QEMU with VNC on a UNIX domain socket. An unprivileged user which cannot access the UNIX domain socket, can then connect to QEMU's VNC server by passing an open FD to libvirt, which passes it onto QEMU. { "execute": "get_fd", "arguments": { "fdname": "myclient" } } { "return": {} } { "execute": "add_client", "arguments": { "protocol": "vnc", "fdname": "myclient", "skipauth": true } } { "return": {} } In this case 'protocol' can be 'vnc' or 'spice', or the name of a character device (eg from -chardev id=XXXX) The 'skipauth' parameter can be used to skip any configured VNC authentication scheme, which is useful if the mgmt layer talking to the monitor has already authenticated the client in another way. * console.h: Define 'vnc_display_add_client' method * monitor.c: Implement 'client_add' command * qemu-char.c, qemu-char.h: Add 'qemu_char_add_client' method * qerror.c, qerror.h: Add QERR_ADD_CLIENT_FAILED * qmp-commands.hx: Declare 'client_add' command * ui/vnc.c: Implement 'vnc_display_add_client' method Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
