+
+ dri2: don't schedule a flip prematurely at ScheduleSwap time
+
+ If divisor is 0 but the current MSC is behind the target, we shouldn't
+ schedule a flip (which will occur at the next vblank) or we'll end up
+ displaying it early and returning the wrong timestamp.
+
+ Preserve the optimization though by allowing us to schedule a flip if
+ both the divisor is 0 and the current MSC is equal to or ahead of the
+ target; this avoids a round trip through the kernel.

+
+ If we submit a batch early (for example if the GPU is idle), then submit

+ between the clear at the start of the cycle and then the overdraw later.

+
+ sna: Only flush before adding fresh surfaces to the batch
+
+ Previously, before every operation we would look to see if the GPU was
+ idle and we were running under a DRI compositor. If the GPU was idle, we
+ would flush the batch in the hope that we reduce the cost of the context
+ switch and copy from the compositor (by completing the work earlier).
+ However, we would complete the work far too earlier and as a result
+ would need to flush the batch before every single operation resulting in
+ extra overhead and reduced performance. For example, the gtkperf
+ circles benchmark under gnome-shell/compiz would be 2x slower on
+ Ivybridge.

+Release 2.20.16 (2012-12-15)
+============================
+Rejoice! We have found a trick to make 830gm/845g stable at long last.
+Ever since the switch to GEM and dynamic video memory, those early
+second generation chipsets have been plagued by instability. The lack of
+flushing cachelines from the CPU to GMCH was eventually solved by using
+an undocmented bit, but 830/845 were still hanging under memory pressure.
+These deaths were all due to garbage finding its way into the command
+streamer, and they go away if we take a leaf out of the original driver
+and never reuse those pages for anything else. So for the first time
+ever, I have been able to complete running the test suite on an 845g,
+even whilst thrashing the page and buffer caches!
+
+ * Run the SF stage as single-threaded on gen4 to workaround a few issues
+ https://bugs.freedesktop.org/show_bug.cgi?id=57410
+
+ * Keep the scanout SURFACE_STATE separate to avoid overriding its
+ memory access control on gen6/7 (i.e. writes to the scanout need to
+ be kept out of the render cache)
+
+ * Tune batch flushing after an operation to an exported surface under a
+ compositor.
+
+ * Make sure the source is on the CPU for inplace composition of trapezoids
+ using the CPU
+ https://bugs.freedesktop.org/show_bug.cgi?id=56825
+
+ * Immediately flush in the block hander after a split batch to reduce
+ latency between the two halves of an operation.
+ https://bugs.freedesktop.org/show_bug.cgi?id=51718
+
+ * Install a fallback config if we fail to install the desired config
+ at VT switch (i.e. booting, after resume with 3 incompatible pipes on
+ Ivybridge)
+
+ * Pin batches to avoid CS incoherence on 830/845
+ https://bugs.freedesktop.org/show_bug.cgi?id=26345
+
+
Release 2.20.15 (2012-12-03)
============================
And lo, enabling more of the common acceleration paths for gen4 revealed
