2019-06-22drm/amd/display: DCHUB requestors numbers for Navi.Yongqiang Sun
[Why] The DCHub arbiter has a mechanism to dynamically rate limit the DCHub request stream to the fabric. If the memory controller is fully utilized and the DCHub requestors are well ahead of their amortized schedule, then it is safe to prevent the next winner from being committed and sent to the fabric. The utilization of the memory controller is approximated by ensuring that the number of outstanding requests is greater than a threshold specified by the ARB_MIN_REQ_OUTSTANDING. To determine that the DCHub requestors are well ahead of the amortized schedule, the slack of the next winner is compared with the ARB_SAT_LEVEL in DLG RefClk cycles.

2019-06-22drm/amd/display: Properly guard display_mode_vba with DCN2Leo Li
[Why] display_mode_vba is for DCN2 and up. When building for upstream (DCN1 enabled only), there will be a build error, since display_mode_vba.c/h is stripped out. Note that building DCN1 only with internal dal-dev is still fine, since display_mode_vba.h is not stripped out internally - only in upstream. The make directives therefore stll work, and so will any #include's. [How] Since subsequent generations require DCN2 enabled anyways, guard the makefile directive for display_mode_vba.o with DCN2. Guard any includes with DCN2. In addition, guard the entire contents of display_mode_vba.h with DCN2, to simulate the file being stripped out in upstream. A forward declaration for 'struct display_mode_lib' also needs to be added in display_mode_lib.h. Previously, display_mode_vba.h contained the forward declaration, and display_mode_lib.h in turn included it. This won't work if mode_vba.h is stripped out, requring mode_lib.h to do so itself.
