+ testing for Hexagon
+From: Nathan Chancellor <nathan@kernel.org>

+
+Building rkvdec-vdpu383-h264.c can take a few hours to finish building
+with Clang 20.1.0 or newer when compile testing for Hexagon. While this
+is further investigated and understood on the LLVM side [1], disable
+CONFIG_VIDEO_ROCKCHIP_VDEC when compile testing for Hexagon.
