From 97e272928e62fad34396dd2e25158bacecb2b7eb Mon Sep 17 00:00:00 2001 From: Hawking Zhang Date: Fri, 12 Mar 2021 22:25:07 +0800 Subject: [PATCH] drm/amdgpu: update ecc query support for arcturus arcturus and sienna_cichlid share the same version of umc_info interface (umc_info v33). arcturus uses umc_config to indicate ECC capability, while sienna_cichlid uses umc_config1 to indicate ECC capability. driver needs to check either umc_config or umc_config1 to decide ECC capability for ASICs that use umc_info v33 interface.
