From aa78801f0a6cfeaf3d16b4333239c0b862f73c10 Mon Sep 17 00:00:00 2001 From: Paulo Zanoni Date: Fri, 24 Jan 2020 14:41:25 -0800 Subject: [PATCH] intel/device: bdw_gt1 actually has 6 eus per subslice Found by inspection, I'm not aware of any bugs caused by this typo. According to Lionel, it seems we only use this to generate masks of available EUs for perfromance queries, and it's only used when we can't query the fused parts of the GPU through DRM_IOCTL_I915_QUERY. So this patch should help for the corner case where the Kernel is too old to support the query ioctl. v2: improve commit message, cc stable (Lionel).
