New Features in this Release
The following list summarizes the new features in this release:
• New SVA script to achieve Framelock
This SVA release includes a new script, named svaframelock.sh, to achieve Framelock
in SVA. A new manpage, svaframelock(1) is included in this release. This script provides
improved framelock functionality compared to the existing svacontrolframelock. The
svacontrolframelock script can framelock only the first display output of each X server.
The svaframelock script must be used when the functionality provided by
svacontrolframelock is not sufficient.
A new parameter SVA_FRAMELOCK_PORTS was introduced in the sva.conf file for finer
control of framelock on a display surface.
