From 8e6e054da6c72210966c82f7d3e7a3d014bd0b39 Mon Sep 17 00:00:00 2001 From: Hawking Zhang Date: Mon, 7 Jun 2021 11:02:13 +0800 Subject: [PATCH] drm/amdgpu: cache psp runtime boot_cfg_bitmask in sw_int PSP runtime boot_cfg_bitmask carries various psp bl feature bit mask that can be used by driver. Cache it in sw_init for further usage.
