For ASICs like renoir/arct, driver doesn't need to load mec2 jt. when mec1 jt is loaded, mec2 jt will be loaded automatically since the write is actaully broadcasted to both. We need to more time to test other gfx9 asic. but for now we should be able to draw conclusion that mec2 jt is not needed for renoir and arct. Signed-off-by:

Laptops with AMD APU doesn't restore display backlight brightness after system resume. This issue started when DC was introduced. Let's use BL_CORE_SUSPENDRESUME so the backlight core calls update_status callback after system resume to restore the backlight level. Tested on Dell Inspiron 3180 (Stoney Ridge) and Dell Latitude 5495 (Raven Ridge). Signed-off-by:

[Why] We need to manage the content protection property changes for different usecase, once cp is DESIRED we need to maintain the ENABLED/DESIRED status for different cases. [How] 1. Attach the content_protection property 2. HDCP enable (UNDESIRED -> DESIRED) call into the module with the correct parameters to start hdcp. Set cp to ENABLED 3. HDCP disable (ENABLED -> UNDESIRED) Call the module to disable hdcp. 3. Handle Special cases (Hotplug, S3, headless S3, DPMS) If already ENABLED: set to DESIRED on unplug/suspend/dpms, and disable hdcp Then on plugin/resume/dpms: enable HDCP Signed-off-by:

[Why] When more than 2 displays are connected to the graphics card, only the minimum memory clock is needed. However, when more displays are connected, the minimum memory clock is not sufficient enough to support the overwhelming bandwidth. System will hang under this circumstance. Also, the old code didn't address HBM cards, which has 2 pseudo channels. We need to add the HBM part here. [How] When graphics card connects to 2 or more displays, switch to high memory clock. Also, choose memory multiplier based on whether its regular DRAM or HBM. Signed-off-by:

Previously 8k30 worked with dsc and odm combine due to a workaround that ran the formula a second time with dsc support enable should dsc validation fail. This worked when clocks were low enough for formula to enable odm to lower voltage, however now broke due to increased clocks. This change updates the ODM combine policy within the formula to properly reflect our current policy within DC, only enabling ODM when we have to, as well as adding a check for viewport width when dsc is enabled. As a side effect the redundant call to dml when odm is required is now unnecessary. Signed-off-by:

[WHY] Presently, there is no way for clocks to be lowered, only raised. [HOW] Compare clock status against previous known clock status, and optimize if different. This requires re-ordering the layout of the dc_clocks structure, as the current ordering allows identical clock states to appear different. Signed-off-by:

[why] Some ODM-related register settings are inconsistently updated by VBIOS, causing the state in DC to be invalid, which would then end up crashing in certain use-cases (such as disable/enable device). [how] Check the enabled status of the second pipe when determining the number of OPTC sources. If the second pipe is disabled, set the number of sources to 1 regardless of other settings (that may not be updated correctly). Signed-off-by:

[Why] A lot of the time, the backlight characteristic curve maps min backlight to a non-zero value. But there are cases where we want the curve to intersect at 0. In this scenario even if OS never asks to set 0% backlight, the ABM reduction can result in backlight being lowered close to 0. This particularly can cause problems in some LED drivers, and in general just looks like backlight is completely off. [How] Add default cap to disallow backlight from dropping below 1% even after ABM reduction is applied. Signed-off-by:

[WHY] When changing DPP global ref clock, DTO adjustments must take effect immediately, or else underflow may occur. It appears the original decision to double-buffer DTO adjustments was made to prevent underflows that occur when raising DPP ref clock (which is not double-buffered), but that same decision causes similar issues when lowering DPP global ref clock. The better solution is to order the adjustments according to whether clocks are being raised or lowered. Signed-off-by:
