While old platforms had 3 transcoders and 3 pipes (1:1), HSW has 4 transcoders and 3 pipes. These regs were being used only by HDMI code where pipe is always the same thing as cpu_transcoder. This patch allow us to use them for DP, specially for TRANSCODER_EDP. v2: Adding HSW_TVIDEO_DIP_VSC_DATA to transmit vsc to eDP.

Use the gen3 logic for handling page flip interrupts on gen4. Unfortuantely this kills the stall_check since that looks like it can easily trigger too early. With the current logic the stall check would kick in on the first vblank after the flip has been submitted to the ring. If the CS takes longer than that to process the commands in the ring, the stall check will cause the page flip to be complete too early. That doesn't sound like a very good idea. Something better should be deviced if we still need the stall check. For now, mark i915_pageflip_stall_check() as unused. v2: Fix irq enable_mask and add __always_unused (Chris Wilson) References: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1116587Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Tested-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>

If the interrupt handler were to process a previous vblank interrupt and the following flip pending interrupt at the same time, the page flip would be completed too soon.

Some (but not all) of the HDMI registers can be used to control sDVO, so those registers have two names. IMHO, when we're talking about HDMI, we really should call the HDMI control register "hdmi_reg" instead of "sdvox_reg", otherwise we'll just confuse people reading our code (we now have platforms with HDMI but without SDVO). So now "struct intel_hdmi" has a member called "hdmi_reg" instead of "sdvox_reg". Also, don't worry: "struct intel_sdvo" still has a member called "sdvo_reg". v2: Rebase (v1 was sent in May 2012).

GPU reset will drop all flips that are still in the ring. So after the reset, call update_plane() for all CRTCs to make sure the primary planes are scanning out from the correct buffer. Also finish all pending flips.

Since obj->pending_flips was never set, intel_pipe_set_base() never actually waited for pending page flips to complete. We really do want to wait for the pending flips, because otherwise the mmio surface base address update could overtake the flip, and you could end up with an old frame on the screen once the flip really completes. Just call intel_crtc_wait_pending_flips() prior to calling intel_pipe_set_base() instead of calling just intel_finish_fb() from intel_pipe_set_base(). Moving the call outside of intel_pipe_set_base() avoids calling it twice from the full modeset path. v2: Wait for pending flips w/o holding struct_mutex Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>

HSW no longer has the PIPECONF bit for limited range RGB output. Instead the pipe CSC unit must be used to perform that task. The CSC pre offset are set to 0, since the incoming data is full [0:255] range RGB, the coefficients are programmed to compress the data into [0:219] range, and then we use either the CSC_MODE black screen offset bit, or the CSC post offsets to shift the data to the correct [16:235] range. Also have to change the confiuration of all planes so that the data is sent through the pipe CSC unit. For simplicity send the plane data through the pipe CSC unit always, and in case full range output is requested, the pipe CSC unit is set up with an identity transform to pass the plane data through unchanged. I've been told by some hardware people that the use of the pipe CSC unit shouldn't result in any measurable increase in power consumption numbers.

The FDI link has supported link reversal to make the PCB layout engineer's life easier for quite a while and we have always presered this bit as we programmed FDI_RX_CTL with a read/modify/write sequence. We're trying to take a bit more control over what the BIOS leaves in various register and with the introduction of DDI, started to program FDI_RX_CTL fully. There's a fused bit to indicate DMI link reversal and FDI defaults to mirroring that configuration. We have a bit to override that behaviour that we need to preserve from the BIOS.
