Hi All
guys I am a bit new to this stuff. I want to call a method after user presses a
combination of keys lets say alt+s or whatever. How can I do it using which
event handler.

Since patch ed757e140c0ada220f213036e4497315d24ca8bct, virtio will
sometimes clear all status registers on bus master disable, which loses
information such as VIRTIO_CONFIG_S_FAILED bit. This is a result of
a patch being misapplied: code uses !

Hi.
We (Markus and I) are working on getting QMP forward compatibility
support,
supported. :)
We have a plan for it and I'd like to ask the CC'ed people to review it.
Add missing 32-bit double-word support opcodes.

The {div,divu}2 opcodes are intended for systems for which the
division instruction produces both quotient and remainder. Sparc
is not such a system. Indeed, the remainder must be computed as
quot = a / b
rem = a - (quot * b)
Split out a tcg_out_div32 function that properly initializes Y
The 32-bit right-shift instructions is defined to extend the shifted
output to 64-bits. A shift count of zero therefore is a simple
extension without actually shifting.

Currently the dmg image format driver simply opens the images as raw

of all other image formats which just return an error and let the

Also, bump up the value of the maximum allowed virtqueues to 64. This is

pci_get_byte, pci_get_word, pci_get_long and pci_get_quad
all take a const uint8_t pointer, because they only read
