2020-08-17drm/i915/ddi: Don't rewrite DDI_BUF_CTL reg during DP link trainingImre Deak
The value we program to DDI_BUF_CTL changes at the following places: - At enabling/disabling the output to configure the port width etc, and to enable/disable the DDI BUF function. - At the beginning/end of link re-training to disable/re-enable the DDI BUF function. - On HSW/BDW/SKL to change the voltage swing/pre-emph levels. Except of the above the value we program to the DDI_BUF_CTL register (intel_dp->DP) doesn't change, so no need to reprogram the register when changing the link training patterns (which is programmed via the DP_TP_CTL register on DDI platforms). v2: - Fix the commit message wrt. voltage/pre-emph level values in intel_dp->DP.

2020-08-17drm/i915/ddi: Don't frob the DP link scramble disabling flagImre Deak
According to BSpec this flag should not be changed while the DDI function is enabled. On BDW+ the DP_TP_CTL register spec also states it explicitly that the HW takes care of enabling/disabling the scrambling for training patterns (and it must stay enabled for normal pixel output). Assume that this HW automatic handling of scrambling is also true for HSW.

These if statements are supposed to be true if we ended the list_for_each_entry() loops without hitting a break statement but they don't work. In the first loop, we increment "i" after the "if (i == unit)" condition so we don't necessarily know that "i" is not equal to unit at the end of the loop. In the second loop we exit when mode is not pointing to a valid drm_display_mode struct so it doesn't make sense to check "mode->type".

2020-08-07drm/amdgpu: Fix bug where DPM is not enabled after hibernate and resumeSandeep Raghuraman
Reproducing bug report here: After hibernating and resuming, DPM is not enabled. This remains the case even if you test hibernate using the steps here: https://www.kernel.org/doc/html/latest/power/basic-pm-debugging.html I debugged the problem, and figured out that in the file hardwaremanager.c, in the function, phm_enable_dynamic_state_management(), the check 'if (!hwmgr->pp_one_vf && smum_is_dpm_running(hwmgr) && !amdgpu_passthrough(adev) && adev->in_suspend)' returns true for the hibernate case, and false for the suspend case. This means that for the hibernate case, the AMDGPU driver doesn't enable DPM (even though it should) and simply returns from that function. In the suspend case, it goes ahead and enables DPM, even though it doesn't need to. I debugged further, and found out that in the case of suspend, for the CIK/Hawaii GPUs, smum_is_dpm_running(hwmgr) returns false, while in the case of hibernate, smum_is_dpm_running(hwmgr) returns true. For CIK, the ci_is_dpm_running() function calls the ci_is_smc_ram_running() function, which is ultimately used to determine if DPM is currently enabled or not, and this seems to provide the wrong answer. I've changed the ci_is_dpm_running() function to instead use the same method that some other AMD GPU chips do (e.g Fiji), which seems to read the voltage controller. I've tested on my R9 390 and it seems to work correctly for both suspend and hibernate use cases, and has been stable so far.

2020-08-06drm/amd/display: dchubbub p-state warning during surface planes switchhersen wu
[Why] ramp_up_dispclk_with_dpp is to change dispclk, dppclk and dprefclk according to bandwidth requirement. call stack: rv1_update_clocks --> update_clocks --> dcn10_prepare_bandwidth / dcn10_optimize_bandwidth --> prepare_bandwidth / optimize_bandwidth. before change dcn hw, prepare_bandwidth will be called first to allow enough clock, watermark for change, after end of dcn hw change, optimize_bandwidth is executed to lower clock to save power for new dcn hw settings. below is sequence of commit_planes_for_stream: step 1: prepare_bandwidth - raise clock to have enough bandwidth step 2: lock_doublebuffer_enable step 3: pipe_control_lock(true) - make dchubp register change will not take effect right way step 4: apply_ctx_for_surface - program dchubp step 5: pipe_control_lock(false) - dchubp register change take effect step 6: optimize_bandwidth --> dc_post_update_surfaces_to_stream for full_date, optimize clock to save power at end of step 1, dcn clocks (dprefclk, dispclk, dppclk) may be changed for new dchubp configuration. but real dcn hub dchubps are still running with old configuration until end of step 5. this need clocks settings at step 1 should not less than that before step 1. this is checked by two conditions: 1. if (should_set_clock(safe_to_lower , new_clocks->dispclk_khz, clk_mgr_base->clks.dispclk_khz) || new_clocks->dispclk_khz == clk_mgr_base->clks.dispclk_khz) 2. request_dpp_div = new_clocks->dispclk_khz > new_clocks->dppclk_khz the second condition is based on new dchubp configuration. dppclk for new dchubp may be different from dppclk before step 1. for example, before step 1, dchubps are as below: pipe 0: recout=(0,40,1920,980) viewport=(0,0,1920,979) pipe 1: recout=(0,0,1920,1080) viewport=(0,0,1920,1080) for dppclk for pipe0 need dppclk = dispclk new dchubp pipe split configuration: pipe 0: recout=(0,0,960,1080) viewport=(0,0,960,1080) pipe 1: recout=(960,0,960,1080) viewport=(960,0,960,1080) dppclk only needs dppclk = dispclk /2. dispclk, dppclk are not lock by otg master lock. they take effect after step 1. during this transition, dispclk are the same, but dppclk is changed to half of previous clock for old dchubp configuration between step 1 and step 6. This may cause p-state warning intermittently. [How] for new_clocks->dispclk_khz == clk_mgr_base->clks.dispclk_khz, we need make sure dppclk are not changed to less between step 1 and 6. for new_clocks->dispclk_khz > clk_mgr_base->clks.dispclk_khz, new display clock is raised, but we do not know ratio of new_clocks->dispclk_khz and clk_mgr_base->clks.dispclk_khz, new_clocks->dispclk_khz /2 does not guarantee equal or higher than old dppclk. we could ignore power saving different between dppclk = displck and dppclk = dispclk / 2 between step 1 and step 6. as long as safe_to_lower = false, set dpclk = dispclk to simplify condition check.

2020-08-06drm/amd/display: Disable idle optimizations before programming DCNJun Lei
[Why] Programming DCN is explicitly forbidden during idle optimzations allowed state. Existing implemenation relies on OS/DM, which is not robust. Instead DC should sequence this. Note that DC will not re-enter idle optimized state on its own, it is only responsible for catching out of sequence calls. It is still DM responsibility to sequence appropriate for optimized power, but this change removes the requirement for DM to cover the .1% case.

2020-08-06drm/amd/display: Don't compare dppclk before updating DTOAlvin Lee
[Why] In dcn3_update_clocks there are situations where dppclk is not lowered (i.e. stays the same), but DTO still needs to be increased before we program pipe frontend (i.e. in prepare_bandwidth). If we don't program the new DTO value before we program the pipe, we will underflow as soon as the pipe lock is released until the next call to dcn3_update_clocks where the DTO is updated.
