The targets will, necessarily, need to vary a bit from platform to platform (due to hardware workarounds, etc.), and should exclude the panel/backlight on/off timings. With Chris's patch from earlier applied, as well as a patch for another issue I discovered yesterday, we're already very close to optimal; most time spent is caused by delays in hardware; ACPI/BIOS/hardware) suspend-timings on the platforms I've tested so far (with one bug that needs further investigation). An area to keep a watchful eye on, though, is if we end up with multiple panels/backlights(/segmented panel displays?) that need disabling, since this is currently done in a serial manner. Next up to resume, where Chris is already doing a lot of work.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> </ul> </body> </html>
