You get the little dot mouse that you sometimes see in VNC (its the "show dot when no cursor" option in VNC) when it goes over the QEMU window, but it has no effect - either clicking or moving. This was on Linux host with Windows 2000 guest.

Uh, I tend to say that the overhead is bigger. If you run VNC on the guest installation, not only is the VNC layer *translated*, but you also have the downside of *translated* polling: remember that WinVNC has to look for changes on the screen itself. Xvnc gets told where the screen changes. Alternatively, you could patch QEmu with the rfb patch, which speaks VNC natively. The only problem with the rfb patch I can think of is the mouse. It is just not trivial to turn off mouse acceleration, which is a real pity. In the last weeks, I tried to find a way to emulate a graphics tablet. Unfortunately, I was highly unsuccessful. First, I was not able to find enough documentation for any PS/2 graphics tablet. So, I turned to serial tablets. I came so far as to add a virtual serial device which gets prompted by the driver for a response. But I could not figure out a satisfactory response. Evidently, the Win98 drivers always expect a certain firmware version as response, and refuse to activate graphics tablet support as a consequence. Does anybody on this list have a (working) serial tablet? I'd like to know the activating response, so I can finally finish up the rfb patch. Another possibility would be to write a virtual USB graphics tablet device. Note that this would help non-RFB QEmu, too. You could (finally) use the mouse without grabbing (for some applications, like flight simulators, and certain keyboard shortcuts, you still would need to grab). Ciao, Dscho P.S.: Unfortunately, I will not have much time to work on QEmu in the next weeks, so if you want to work on this, go wild. If you want my alpha code, I'll send it to you. ___ Qemu-devel mailing list Qemu-devel@nongnu.org http://lists.nongnu.org/mailman/listinfo/qemu-devel

Re: [Qemu-devel] Re: Timing problems
Hi, people have had this problem with SpeedStep machines, where it is related to qemu timing being based on CPU cycle count, which is thereby messed up. Since it seems to occur with frequency scaling disabled as well, could this be related to running on a HyperThreading CPU? Not sure what happens there with the cycle counts, but to verify, you could try to apply my previously posted patch that substituted the built-in mechanism with realtime clock calls (was for 0.7.1, though, I think).

[Qemu-devel] ACPI support
Hi there, I use qemu for development of embedded systems. Lately I had a need to check ACPI related kernel module, but I have seen that there isn't any support in the version 0.7.1 that I use. I have checked also 0.7.2 and found no support. A patch that I have found on www.h7.dion.ne.jp/~qemu-win/ for x86_64 by F.Navara seemed like close enough. I have applied it (after adaptation, since it didn't go smooth for 0.7.1 or 0.7.2). The system booted, but running dmesg | grep ACPI inside the embedded system on the qemu gave: ACPI: RSDP (v000 QEMU ) @ 0x000e ACPI: Invalid RSDT checksum ACPI: Subsystem revision 20050211 ACPI: Interpreter disabled. I use the i386 emulation, and the kernel running inside is 2.6.11 Has someone any experience with ACPI in qemu?

RE: [Qemu-devel] ACPI support
This is an interesting topic, however, not an easy task :) The patch is for APIC support, and only contains one ACPI MADT entry, which is far from full ACPI support. So you may like to call it an APIC patch rather than ACPI patch. If you want to test power management of embedded system with qemu, IMHO, there will be a lot of work to do: * Implement ACPI hardware in QEMU, which includes - General ACPI hardware in chipset - Specific ACPI hardware in every device * Add ACPI table in BIOS.

Yep, I was thinking about running RDP in the guest for day-to-day stuff (we do that now for our real Win2k server. The QEMU GUI has to go somewhere though, and short of installing the VNC patch, the easiest option looks like running a virtual X server like the VNC one. QEMU can connect to that and the display goes nowhere, until of course someone connects via VNC. I've started on this, with a Win2k server install and SQL 7 running on my desktop seemingly quite well. After some more testing (loading up some databases, testing apps running under Linux connecting to it through the virtual NIC) I'll start looking at running it on our test SMP server with the VNC X server.

Re: [Qemu-devel] ACPI support
Thanks! Actually, I don't need the whole ACPI mechanism working. On the real target, I want to use the power button to initiate a reboot. Such a thing can be done with something like: cat /proc/acpi/event | grep specific_event > /dev/null && reboot In the qemu, I never get to load the relevant kernel modules (like button.ko), since the ACPI is disabled due to the mentioned checksum failure. If it is only some small adaptation of the mentioned patch with checksum calculation for RSDT and updating acpi.S than I would gladly do it (do you have any hints?). Otherwise - I just give up on this now, and use the real hardware.
