Last change on this file since 73092 was 72778, checked in by vboxsync, 7 years ago

VMM,SUPDrv,IPRT: Redirect ring-0 release logging on EMTs to VBox.log.

  • VMM: Added release ring-0 logging on EMTs that writes to VBox.log.
  • IPRT: Made 'msprog' and 'timeprog' work for ring-0 logging on EMTs.
  • IPRT: Removed RTLogSetCustomPrefixCallbackForR0.
  • VMM: Removed vmmR0LoggerPrefix that was assoicated with the above API.
  • IPRT Fixed missing log prefix on the first log line.
  • SUPDrv: Turns out we require actual code for SUPR0GetDefaultLogRelInstanceEx and SUPR0GetDefaultLogInstanceEx.

Note! Requires updating the support driver.

  • Property svn:eol-style set to native
  • Property svn:keywords set to Id Revision
