2018-07-06drm/i915/selftests: Fixup missing MI_MEM_VIRTUAL for live_hangcheckChris Wilson
We always want to use a virtual address (i.e. use the GTT) for MI_STORE_DWORD_IMM, but forgot the ever so important flag in live_hangcheck for gen3.

2018-07-06drm/i915: Flush the WCB following a WC writeChris Wilson
If we have just completed a WC write, we must ensure that the WCB (Write Combining Buffer) is flushed out to main memory before we can expect to see the results. This is especially important when mixing WC with GTT as the physical paths are different and cachelines are not naturally flushed.

2018-07-06drm/i915/ddi: Simplify get_encoder_power_domains()Imre Deak
We can simplify the encoder's get_power_domains() hook by calling it only if the encoder is active. That way the hook can return its power domains unconditionally without checking the active state by calling encoder::get_hw_state(). This get_hw_state() query is in fact redundant since it's already done by intel_modeset_readout_hw_state() setting the encoder's crtc or leaving it NULL accordingly. Let's use this fact to decide if the encoder is active. While at it clarify the comment in intel_ddi_get_power_domains() about primary vs. fake MST encoders and make sure we never do an incorrect encoder->dig_port cast for fake MST encoders.

We test elsewhere our handling of populating large objects with a full set of VMA and checking we can retrieve them afterwards, but in this test we incur the cost of flushing all VMA after every GTT write, dramatically slowing down the test.

Avoid confusion with the functions to be added for the new ICL or gen 11 DSI implementation by renaming the current DSI functions. While at it, permutate the words in the function names to make them all start with "vlv_dsi" or "vlv_dsi_pll" etc. Reduce the platform abstractions in the PLL file while at it, moving the checks to vlv_dsi.c instead, where we typically already have the necessary if ladders.

2018-07-05drm/amd/display: add a check for display depth validityMikita Lipski
[why] HDMI 2.0 fails to validate 4K@60 timing with 10 bpc [how] Adding a helper function that would verify if the display depth assigned would pass a bandwidth validation. Drop the display depth by one level till calculated pixel clk is lower than maximum TMDS clk.

2018-07-05drm/amd/display: adding ycbcr420 pixel encoding for hdmiMikita Lipski
[why] HDMI EDID's VSDB contains spectial timings for specifically YCbCr 4:2:0 colour space. In those cases we need to verify if the mode provided is one of the special ones has to use YCbCr 4:2:0 pixel encoding for display info. [how] Verify if the mode is using specific ycbcr420 colour space with the help of DRM helper function and assign the mode to use ycbcr420 pixel encoding.

2018-07-05drm/amd/display/dc/dce: Fix multiple potential integer overflowsGustavo A. R. Silva
Add suffix ULL to constant 5 and cast variables target_pix_clk_khz and feedback_divider to uint64_t in order to avoid multiple potential integer overflows and give the compiler complete information about the proper arithmetic to use. Notice that such constant and variables are used in contexts that expect expressions of type uint64_t (64 bits, unsigned). The current casts to uint64_t effectively apply to each expression as a whole, but they do not prevent them from being evaluated using 32-bit arithmetic instead of 64-bit arithmetic. Also, once the expressions are properly evaluated using 64-bit arithmentic, there is no need for the parentheses that enclose them.
