[PATCH AUTOSEL 6.0 36/39] drm/amd/display: Use viewport height for subvp mall allocation size

[PATCH AUTOSEL 6.0 36/39] drm/amd/display: Use viewport height for subvp mall allocation size

[Sasha Levin]

From: Dillon Varone <Dillon.Varone@amd.com>

[ Upstream commit dd2c028c1395d622df7ddd6837f8ab2dc94008ee ]

[WHY?]
MALL allocation size depends on the viewport height, not the addressable
vertical lines, which will not match when scaling.

[HOW?]
Base MALL allocation size calculations off viewport height.

[PATCH AUTOSEL 6.0 37/39] drm/amd/display: Avoid setting pixel rate divider to N/A

[Sasha Levin]

From: Taimur Hassan <Syed.Hassan@amd.com>

[ Upstream commit 2a5dd86a69ea5435f1a837bdb7fafcda609a7c91 ]

[Why]
Pixel rate divider values should never be set to N/A (0xF) as the K1/K2
field is only 1/2 bits wide.

[How]
Set valid divider values for virtual and FRL/DP2 cases.

[PATCH AUTOSEL 6.0 38/39] drm/amd/display: Use new num clk levels struct for max mclk index

[Sasha Levin]

From: Dillon Varone <Dillon.Varone@amd.com>

[ Upstream commit e667ee3b0c049bf0c69426879586a2572bb28d26 ]

[WHY?]
When calculating watermark and dlg values, the max mclk level index and
associated speed are needed to find the correlated dummy latency value.
Currently the incorrect index is given due to a clock manager refactor.

[HOW?]
Use num_memclk_level from num_entries_per_clk struct for getting the correct max
mem speed.
