From bc6387a2e0c1562faa56ce2a98cef50cab809e08 Mon Sep 17 00:00:00 2001 From: Matt Roper Date: Thu, 5 Feb 2026 14:05:09 -0800 Subject: drm/xe/xe2_hpg: Fix handling of Wa_14019988906 & Wa_14019877138 The PSS_CHICKEN register has been part of the RCS engine's LRC since it was first introduced in Xe_LP. That means that any workarounds that adjust its value (such as Wa_14019988906 and Wa_14019877138) need to be implemented in the lrc_was[] table so that they become part of the default LRC from which all subsequent LRCs are copied. Although these workarounds were implemented correctly on most platforms, they were incorrectly placed on the engine_was[] table for Xe2_HPG. Move the workarounds to the proper lrc_was[] table and switch the 'xe_rtp_match_first_render_or_compute' rule to specifically match the RCS since that's the engine whose LRC manages the register.
