[Qemu-devel] Qemu atags passing in register.

2012-02-06 Thread d...@ucore.info
Hi, I'm doing some tricks with Linux kernel and I'm dependent on bootloader atags passing. On PandaBoard the u-boot is always passing DTF/Atags pointer in r2 register, and I'm kind of depending on it. I need to emulate this behavior by -initrd qemu's argument. However it seems that qemu-system-ar

Hi, I'm trying to get the tablet emulation for Qemu's VNC server to handle the mouse better. I'm using `qemu-system-arm` and everything is OK except for the mouse movement. After I add `-usb -usbdevie table` argument to `qemu-system-arm` invocation I get: qemu: hardware error: Failed to create U
