drm/amd/display: fix dcc swath size calculations on dcn1

2020-03-25T07:26:58+00:00

[ Upstream commit a0275dfc82c9034eefbeffd556cca6dd239d7925 ] [Why] Swath sizes are being calculated incorrectly. The horizontal swath size should be the product of block height, viewport width, and bytes per element, but the calculation uses viewport height instead of width. The vertical swath size is similarly incorrectly calculated. The effect of this is that we report the wrong DCC caps. [How] Use viewport width in the horizontal swath size calculation and viewport height in the vertical swath size calculation.

drm/amd/display: Clear link settings on MST disable connector

amdgpu: Prevent build errors regarding soft/hard-float FP ABI tags

2020-03-05T15:45:08+00:00

[ Upstream commit 416611d9b6eebaeae58ed26cc7d23131c69126b1 ] On PowerPC, the compiler will tag object files with whether they use hard or soft float FP ABI and whether they use 64 or 128-bit long double ABI. On systems with 64-bit long double ABI, a tag will get emitted whenever a double is used, as on those systems a long double is the same as a double. This will prevent linkage as other files are being compiled with hard-float. On ppc64, this code will never actually get used for the time being, as the only currently existing hardware using it are the Renoir APUs. Therefore, until this is testable and can be fixed properly, at least make sure the build will not fail. Signed-off-by: Daniel Kolesa Signed-off-by: Alex Deucher Signed-off-by: Sasha Levin

drm/amd/display: Add initialitions for PLL2 clock source

[ Upstream commit c134c3cabae46a56ab2e1f5e5fa49405e1758838 ] [Why] Starting from 14nm, the PLL is built into the PHY and the PLL is mapped to PHY on 1 to 1 basis. In the code, the DP port is mapped to a PLL that was not initialized. This causes DP to HDMI dongle to not light up the display. [How] Initializations added for PLL2 when creating resources.
