[Why] We only allowed 1 overlay plane. But now some ASICS can support multiple overlay planes. [How] Use max_slave_planes as the number of overlays we can support. Also since we cannot draw cursor over a video plane, we need to make sure that we reject commits where the topmost plane is a video plane (overlay only). Reviewed-by:

[why] Link is a subcomponent in dc. DM should be aware of dc link structure as one of the abstracted objects maintained by dc. However it should have no idea of the existence of a link component in dc dedicated to maintain the states of dc link structure. As such we are moving link interfaces out of dc_link.h and directly added to dc.h. We are grandually fading out the explicit inclusion of dc_link header and eventually delete it. On dc side, since link is a subcomponent behind dc interfaces, it is not a good idea to implement dc interfaces in each individual subcomponent of link which is already a subcomponent of dc. So we are decoupling it by implementing a dc_link_exports in dc. This file will be a thin translation layer that breaks the dependency so link is able to make interface changes without breaking DM.

[why] HUBP_UNBOUNDED_REQ_MODE being enabled while the display is rotated (eg. going from Portrait mode to Landscape mode) appears to be causing a p-state hang, specifically during full screen mode on the Tiktok PC app. Unbounded request mode doesn't appear to be supported with rotation configs, hence disabling it. [how] Within DML, modified unbounded request mode to be configured only when the rotation angle of the plane is 0. Reviewed-by:

[Why] Regression of commit 72fef498 ("drm/amdgpu: Remove writing GRBM_GFX_CNTL in RLCG interface under SRIOV") on GFX9. According to GFX9 VF using different method to access GC registers including MMIO(direct) and RLCG(indirect), removing GRBM_GFX_* writing would make PIPE/ME/VM/QUEUE selection chaos leading to some OCL benchmark failure. For example, using RLCG interface to program GRBM_GFX_CNTL/INDEX for selecting MEC(actually the value is only in scratch2/3), then using MMIO directly program a MEC register in VF driver. The register programming are invalid due to GC switched to incorrect ME. [How] With checking RLCG accessing flag, keep writing GRBM_GFX_* as a legacy way. But it is still skipped on GFX10+ to avoid violation occurrence. Signed-off-by:

[why] Newer ASICs such as DCN314 needs to allow for both self refresh and mem clk switching rather than just self refresh only. Otherwise, we can see some p-state hangs on ASICs that do support mem clk switching. [how] Added an allow_self_refresh_only flag for dcn30_internal_validate_bw and created a validate_bw method for DCN314 with the allow_self_refresh_only flag set to false (to support mem clk switching).
