2022-04-06Replace config-time define HOST_WORDS_BIGENDIANMarc-André Lureau1-1/+1
Replace a config-time define with a compile time condition define (compatible with clang and gcc) that must be declared prior to its usage. This avoids having a global configure time define, but also prevents from bad usage, if the config header wasn't included before. This can help to make some code independent from qemu too. gcc supports __BYTE_ORDER__ from about 4.6 and clang from 3.2.

2021-12-21ui/vdagent: add serial capability supportMarc-André Lureau1-1/+38
The Spice agent implements a simple serial mechanism to avoid clipboard races between client & guest.

2021-08-31ui/vdagent: add a migration blockerMarc-André Lureau1-0/+12
The current implementation lacks migration support. After migration, vdagent support will be broken (even after a restart of the daemons). Let's try to fix it in 6.2.

2021-05-21ui/vdagent: add clipboard supportGerd Hoffmann1-0/+293
This patch adds support for clipboard messages to the qemu vdagent implementation, which allows the guest exchange clipboard data with qemu. Clipboard support can be enabled/disabled using the new 'clipboard' parameter for the vdagent chardev. Default is off.

2021-05-21ui/vdagent: core infrastructureGerd Hoffmann1-0/+361
The vdagent protocol allows the guest agent (spice-vdagent) and the spice client exchange messages to implement features which require guest cooperation, for example clipboard support. This is a qemu implementation of the spice client side. This allows the spice guest agent talk to qemu directly when not using the spice protocol. usage: qemu \ -chardev qemu-vdagent,id=vdagent \ -device virtserialport,chardev=vdagent,name=com.redhat.spice.0 This patch adds just the protocol basics: initial handshake and capability negotiation. The following patches will add actual functionality and also add fields to the initially empty ChardevVDAgent qapi struct.
