| * Merge tag 'omapdss-for-3.7' of git://gitorious.org/linux-omap-dss2/linux ↵Florian Tobias Schandinat2012-10-1016-123/+169
| |\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

However, as Ville Syrjala pointed out, we set the pending flip notification on the old framebuffer that is no longer attached to the CRTC by the time we come to flush the pending operations. Instead, we can simply wait on the pending unpin work to be finished on this CRTC, knowning that the hardware has therefore finished modifying the registers, before proceeding with our direct access. Fixes i-g-t/flip_test on non-pch platforms. pch platforms simply schedule the flip immediately when the pipe is disabled, leading to other funny issues.

However, the stated w/a for hardware contexts is that the TLBs must be invalidated prior to a MI_SET_CONTEXT, yet the w/a itself did not request the TLBs to be invalidated...

However, the BPC was clamped by VBT settings, making things work by coincidence, until that part was removed in commit 4344b813f105a19f793f1fd93ad775b784648b95 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Fri Aug 10 11:10:20 2012 +0200 Use adjusted_mode instead of mode when checking for INTEL_MODE_DP_FORCE_6BPC to make the flag have effect. v2: Don't forget to fix this in i9xx_crtc_mode_set() also, pointed out by Daniel both before and after sending the first patch.
