Since they're all the same register, leave all the #defines at the same place, organized by Gen and also specify which bits are used by only a specific port or encoding. Also remove a few unused duplicates and adjust indentation. Signed-off-by:

Some HDMI registers can be used for SDVO, so saying "HDMIB" should be the same as saying "SDVOB" for a given HW generation. This was not true and led to confusions and even a regression. Previously we had: - SDVO{B,C} defined as the Gen3+ registers - HDMI{B,C,D} and PCH_SDVOB defined as the PCH registers But now: - SDVO{B,C} became GEN3_SDVO{B,C} on SDVO code - SDVO{B,C} became GEN4_HDMI{B,C} on HDMI code - HDMI{B,C,D} became PCH_HDMI{B,C,D} - PCH_SDVOB is still the same thing v2: Rebase (v1 was sent in May 2012).

Kill the HSW check from the single thread force wake code. HSW uses MT force wake exclusively these days. The commit that removed HSW single thread forcewake support: commit 36ec8f87 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Thu Oct 18 14:44:35 2012 +0200 drm/i915: unconditionally use mt forcewake on hsw/ivb Signed-off-by:

Use the number '1' instead of FORCEWAKE_KERNEL when requesting single thread force wake since there is only one bit in the register. Using the FORCEWAKE_KERNEL name might give someone the wrong impression. Signed-off-by:

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. Signed-off-by:

The indentation is getting way too deep. Pull the vblank interupt handling out to separate functions. v2: Keep flip_mask handling in the main irq handler and flatten {i8xx,i915}_handle_vblank() even further. Signed-off-by: -
Ville Syrjälä authored
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:

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. To eliminate this race, check the live pending flip status from the ISR register before finishing the page flip. v2: Added a comment explaining the logic (by Chris Wilson) v3: Fix a typo in the comment Reviewed-by:

We plan to treat GEN7_ERR_INT as an interrupt, so use this register for the checks inside I915_WRITE.

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. That means user space will get its page flip events and won't get stuck waiting for them. v2: Explicitly finish page flips instead of relying on FLIP_DONE interrupt being generated by the base address update. v3: Make two loops over crtcs to avoid deadlocks with the crtc mutex Signed-off-by: -
Ville Syrjälä authored
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:

KMS drivers can potentially restore the display configuration without userspace help. Such drivers can can call a new funciton, pm_vt_switch_required(false) if they support this feature. In that case, the PM layer won't VT switch to the suspend console at suspend time and then back to the original VT on resume, but rather leave things alone for a nicer looking suspend and resume sequence. v2: make a function so we can handle multiple drivers (Alan) v3: use a list to track device requests (Rafael) v4: Squash in build fix from Jesse for CONFIG_VT_CONSOLE_SLEEP=n v5: Squash in patch from Wu Fengguang to add a few missing static qualifiers. v6: Add missing EXPORT_SYMBOL.

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. Signed-off-by:
