2019-08-15drm/amdgpu: Set VM_L2_CNTL.PDE_FAULT_CLASSIFICATION to 0 for GFX10Yong Zhao
We have done this for pre-GFX10 asics, but GFX10 did not pick up the new change. The below is the commit message for that change. This is recommended by HW designers. Previously when it was set to 1, the PDE walk error in VM fault will be treated as PERMISSION_OR_INVALID_PAGE_FAULT rather than usually expected OTHER_FAULT. As a result, the retry control in VM_CONTEXT*_CNTL will change accordingly. The above behavior is kind of abnormal. Furthermore, the PDE_FAULT_CLASSIFICATION == 1 feature was targeted for very old ASICs and it never made it way to production. Therefore, we should set it to 0.

2019-08-15drm/amd/display: Remove duplicate interface for programming FBJulian Parkin
[Why] There are currently two interfaces for exactly the same thing: hupb_update_dchub in hupb and update_dchub in hubbub. The hubbub version is currently unused past dcn10, largely because the call from the dcn10 hardware sequencer does not call through the interface, so the hupb interface was used instead. This is confusing because of the duplicate code, the unused functions, and the fact that more that one block currently owns this set of registers. [How] Remove the hubp interface entirely, as well as the register declarations that are not longer needed because of this. Change the call site to always call the hubbub version through the interface. Fix the update_dchub function in dcn20_hubbub.c to program the correct registers for dcn20.

[why] Resource mapping done in dcn20_validate_bandwidth has a flaw: When a full update is performed, the HWSS will only update the MPCC tree for the stream that is updated as opposed to all streams. This means that when mapping pipes in validation, care must be taken to not change any existing mapping, otherwise it leads to partial hw programming [how] it's not strictly necessary to track which stream/mpcc tree is being updated, but rather it's sufficient to compare current and new state and just keep pipes that were previously already mapped unchanged.

2019-08-15drm/amd/display: Set DSC before DIG front-end is connected to its back-endNikola Cornij
[why] At the time DIG FE is connected to its BE, the clocks in OTG are enabled and PHY will also be set up. When DSC has to be used to fit the stream into the available bandwidth, without DSC being set DIG could get exposed to the higer bandwidth it (or link) could handle. This causes the HW to "reject" video enable setup (the register shows that video enable was attempted, but the status bit shows it as disabled). [how] - Separate DSC setup into DSC register config and DSC PPS SDP setup - Move most of the DSC setup (register config) to before dcn10_link_encoder_connect_dig_be_to_fe() is called - Set up DSC PPS SDP after DIG FE is connected to its BE. This is because setting DSC PPS SDP before that has no effect.

2019-08-15drm/amd/display: fixup DPP programming sequenceJun Lei
[why] DC does not correct account for the fact that DPP DTO is double buffered while DPP ref is not. This means that when DPP ref clock is lowered when it's "safe to lower", the DPP blocks that need an increased divider will temporarily have actual DPP clock drop below minimum while DTO double buffering takes effect. This results in temporary underflow. [how] To fix this, DPP clock cannot be programmed atomically, but rather be broken up into the DTO and the ref. Each has a separate "safe to lower" logic. When doing "prepare" the ref and dividers may only increase. When doing "optimize", both may decrease. It is guaranteed that we won't exceed max DPP clock because we do not use dividers larger than 1.

[Why] The math on deciding on how many "frames to insert" sometimes sent us over the max refresh rate. Also integer overflow can occur if we have high refresh rates. [How] Instead of clipping the frame duration such that it doesn’t go below the min, just remove a frame from the number of frames to insert. + Use unsigned long long for intermediate calculations to prevent integer overflow.
