[Why] Video Timing Extended Metadata packet (VTEM) is not specific to freesync. So move it out of freesync module [How] - Moved VTEM from freesync module to info_packet module - Created new structure for VTEM parameters that can be used for VRR and FVA Signed-off-by: Ahmad Othman Reviewed-by: Chris Park Acked-by: Ahmad Othman Acked-by: Bhawanpreet Lakha Signed-off-by: Alex Deucher

drm/amd/display: load iram for abm 2.3

2019-08-23T16:37:24Z

[Why] ABM 2.3 firmware expects information in iRAM that differs from previous versions of ABM, so a mechanism is required to provide it with that information. [How] Extend the existing iRAM definition to include parameters added by ABM 2.3, and load it if DMCU is running ABM 2.3.

drm/amd/display: Fix frames_to_insert math

2019-08-15T15:53:12Z

[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.

drm/amd/display: Optimize gamma calculations

2019-07-18T19:27:25Z

[Why&How] 1. Stack usage is pretty high as fixed31_32 struct is 8 bytes and we have functions with >30 vars on the stack. 2. Optimize gamma calculation by reducing number of calls to dc_fixpt_pow Our X points are divided into 32 regions wth 16 pts each. Each region is 2x the previous, meaning x[i] = 2*x[i-16] for i>=16. Using (2x)^gamma = 2^gamma * x^gamma, we can recursively compute powers of gamma, we just need first 16 pts to start it up. dc_fixpt_pow() is expensive, it computes x^y by doing exp(y*logx) Exp is done by Taylor series approximation, and log by Newton-like approximation that also uses exp internally. In short, it's significantly heavier than run-of-the-mill addition/subtraction/multiply.
