Merge tag 'omapdss-for-3.7' of git://gitorious.org/linux-omap-dss2/linux into fbdev-next
Omapdss driver changes for the 3.7 merge window.
Notable changes:
* Basic writeback support for DISPC level. Writeback is not yet usable, though,
as we need higher level code to actually expose the writeback feature to
userspace.
* Rewriting the omapdss output drivers. We're trying to remove the hard links
between the omapdss and the panels, and this rewrite work moves us closer to
that goal.
* Cleanup and restructuring patches that have been made while working on device
tree support for omapdss. Device tree support is still some way ahead, but
these patches are good cleanups in themselves.
* Basic OMAP5 DSS support for DPI and DSI outputs.
* Workaround for the problem that GFX overlay's fifo is too small for high
resolution scenarios, causing underflows.
* Cleanups that remove dependencies to omap platform code.

Default value +for this is 2. + +slice_sync +---------- +When a queue is selected for execution, the queues IO requests are only +executed for a certain amount of time(time_slice) before switching to another +queue. This parameter is used to calculate the time slice of synchronous +queue. + +time_slice is computed using the below equation:- +time_slice = slice_sync + (slice_sync/5 * (4 - prio)). To increase the +time_slice of synchronous queue, increase the value of slice_sync. Default +value is 100ms. + +quantum +------- +This specifies the number of request dispatched to the device queue. In a +queue's time slice, a request will not be dispatched if the number of request +in the device exceeds this parameter. This parameter is used for synchronous +request. + +In case of storage with several disk, this setting can limit the parallel +processing of request.
