Re: [Intel-gfx] [PATCH 4/4] drm/i915/dg1: WA GPU hang at RCC

Yes, that's the case. It has RCC related silicon issues in gen12-lp. Followings are two consecutive GPU hangs we found in SG1 and DG1 linux which have no media compressible render target. 1. HSD-1508524297 [SG1][DG1] GPU hang in PIPECONTROL in running 1

[Intel-gfx] [PATCH 4/4] drm/i915/dg1: WA GPU hang at RCC

From: Zhen Han GPU hangs at RCC. According to Wa_14012131227 we shouldn't have a hang due to RHWO, but that is what we are observing, even without media compressible render target. Feedback from HW engineers is to leave RHWO disabled. Cc: Jianjun Liu Cc: Chuansheng Liu Cc: Radhakrishna Sripada
