2673	Introducing dynamic buffer queue scaling to minimize lag. Introducing dynamic buffer queue scaling to minimize lag. (LP: #1240909) Actually the size of the queue doesn't really change with this branch. What it does do is reliably detect when a client is staying ahead of the compositor and throttle it so that no more than one future frame is ever pre-rendered. Hence you get the same single-frame latency as double buffering. But the moment the client fails to keep up, it will get to use all three buffers again. Fixes: https://bugs.launchpad.net/bugs/1240909, https://bugs.launchpad.net/bugs/1274408. Approved by Cemil Azizoglu, Alexandros Frantzis, PS Jenkins bot.	Daniel van Vugt		8 years ago
2289	Fix dangerous underestimate of buffers_ready_for_compositor(... Fix dangerous underestimate of buffers_ready_for_compositor(). This is an immediate problem when you start experimenting with double buffers, and see occasional random freezes. (LP: #1395581) It could also possibly affect the current triple buffering used for multimonitor and bypass/overlays. Fixes: https://bugs.launchpad.net/bugs/1395581.

2218	mesa::DisplayBuffer: Schedule page flips in a double buffere... mesa::DisplayBuffer: Schedule page flips in a double buffered pattern instead of triple when it's safe to do so (not clone mode). This noticeably reduces visible lag. (LP: #1350725) Clone mode still needs triple buffering because you can't tell two or more separate monitors to vblank at the same time. You just have to accept that waiting for multiple vblanks will often take an extra frame's time. The more common cases of single or separate outputs however only need to deal with one vsync signal per frame so can be optimized into double buffering. And this feels significantly less laggy when dragging windows around. This is an improvement on the present behaviour introduced in r1380. Fixes: https://bugs.launchpad.net/bugs/1274408, https://bugs.launchpad.net/bugs/1350725. Approved by PS Jenkins bot, Robert Carr, Alexandros Frantzis, Alan Griffiths.	Daniel van Vugt		9 years ago

2118	Use popen() natively instead of pumping it through boost-ios... Use popen() natively instead of pumping it through boost-iostreams. This reduces build dependencies as well as binary sizes significantly: mir_performance_tests shrinks by 253KB (13%) libmir-test.a shrinks by 474KB (20%)	Daniel van Vugt		9 years ago
2117	Ensure frame dropping never drops the newest frame. Dropping... Ensure frame dropping never drops the newest frame. Dropping the newest frame causes stuttering at best (LP: #1379685) or in the case of an event-driven app could make it appear to freeze indefinitely (LP: #1396006).	Daniel van Vugt		9 years ago
2109	Remove dead code: Internal* classes Remove dead code: Internal* classes Only used in platform-api, but arguably shouldn't be. Approved by PS Jenkins bot, Alberto Aguirre, Alan Griffiths, Cemil Azizoglu, Gerry Boland, Alexandros Frantzis.	Daniel van Vugt		9 years ago

We have been needing to be a bit more honest about our library dependencies. And this will make our build/release process more robust.

1929	Introduce explicit driver ABI levels: Introduce explicit driver ABI levels: libmirplatformNdriver, libmirclientMdriver This should finally resolve parallel install/upgrade problems (LP: #1293944) which are now also starting to block CI, and will also block the release of Mir 0.8.0 if not 0.9.0. As our graphics drivers both link to and are loaded by libmirplatform.so.N, they are already tightly bound to mirplatform ABI level N, and nothing else. So that's why the same number N is being used in the driver file names: libmirplatformNdriver.so. The same goes for libmirclientMdriver and libmirclient.so.M. Fixes: https://bugs.launchpad.net/bugs/1293944. Approved by PS Jenkins bot, Cemil Azizoglu.	Daniel van Vugt		9 years ago

Rename include.private to src/include Scrub examples to remove some private header dependencies. . Approved by PS Jenkins bot, Kevin DuBois, Alexandros Frantzis, Daniel van Vugt.
