2014-07-17drm/radeon: Make classic pageflip completion path less racy.Mario Kleiner
Need to protect mmio flip programming by event lock as well. Need to also first enable pflip irq, then mmio program, otherwise a flip completion may get unnoticed in the vblank of actual completion if the flip is programmed, but radeon_flip_work_func gets preempted immediately after mmio programming and before vblank. In that case the vblank irq handler wouldn't run radeon_crtc_handle_vblank() with the completion check routine, miss the completed flip, and only notice one vblank after actual completion, causing a false/delayed report of flip completion.

2014-07-17drm/radeon: Prevent too early kms-pageflips triggered by vblank.Mario Kleiner
Since 3.16-rc1 we have this new failure: When the userspace XOrg ddx schedules vblank events to trigger deferred kms-pageflips, e.g., via the OML_sync_control extension call glXSwapBuffersMscOML(), or if a glXSwapBuffers() is called immediately after completion of a previous swapbuffers call, e.g., in a tight rendering loop with minimal rendering, it happens frequently that the pageflip ioctl() is executed within the same vblank in which a previous kms-pageflip completed, or - for deferred swaps - always one vblank earlier than requested by the client app. This causes premature pageflips and detection of failure by the ddx, e.g., XOrg log warnings like... "(WW) RADEON(1): radeon_dri2_flip_event_handler: Pageflip completion event has impossible msc 201025 < target_msc 201026" ... and error/invalid return values of glXWaitForSbcOML() and Intel_swap_events extension. Reason is the new way in which kms-pageflips are programmed since 3.16. This commit changes the time window in which the hw can execute pending programmed pageflips. Before, a pending flip would get executed anywhere within the vblank interval. Now a pending flip only gets executed at the leading edge of vblank (start of front porch), making sure that a invocation of the pageflip ioctl() within a given vblank interval will only lead to pageflip completion in the following vblank.

If qxl is initialized before A and A's irq was raised during this gap, returning IRQ_HANDLED in this case will cause this irq to be raised again after EOI since kernel think it was handled but in fact it was not.

2014-07-09drm/i915: Only unbind vgacon, not other console driversDaniel Vetter
The console subsystem only provides a function to switch to a given console, but we want to actually only switach away from vgacon. Unconditionally switching to the dummy console resulted in switching away from fbcon in multi-gpu setups when other gpu drivers are loaded before i915. Then either the reinitialization of fbcon when i915 registers its fbdev emulation or the teardown of the fbcon driver killed the machine. So only switch to the dummy console when it's required. Kudos to Chris for the original idea, I've only refined it a bit to still unregister vgacon even when it's currently unused.

2014-07-04drm/i915: provide interface for audio driver to query cdclkJani Nikula
For Haswell and Broadwell, if the display power well has been disabled, the display audio controller divider values EM4 M VALUE and EM5 N VALUE will have been lost. The CDCLK frequency is required for reprogramming them to generate 24MHz HD-A link BCLK. So provide a private interface for the audio driver to query CDCLK. This is a stopgap solution until a more generic interface between audio and display drivers has been implemented.

2014-07-03drm/vmwgfx: Fix incorrect write to read-only register v2:Thomas Hellstrom
Commit "drm/vmwgfx: correct fb_fix_screeninfo.line_length", while fixing a vmwgfx fbdev bug, also writes the pitch to a supposedly read-only register: SVGA_REG_BYTES_PER_LINE, while it should be (and also in fact is) written to SVGA_REG_PITCHLOCK. This patch is Cc'd stable because of the unknown effects writing to this register might have, particularly on older device versions. v2: Updated log message.
