From: John Harrison <John.C.Harrison@xxxxxxxxx> The above two workaronuds regarding context isolation are implemented by GuC. The KMD just needs to enable them. v2: Use dg2 stepping for ctx isolation WA (Umesh) v3: Rebase (Umesh) v4: Fix WA comments (Daniele) v5: Drop Wa_22012727685 for G10 as it is n/a v6: Undo v5 change since the G10 condition is needed Signed-off-by: John Harrison <John.C.Harrison@xxxxxxxxx> --- drivers/gpu/drm/i915/gt/uc/intel_guc.c | 8 ++++++++ drivers/gpu/drm/i915/gt/uc/intel_guc_fwif.h | 1 + 2 files changed, 9 insertions(+) diff --git a/drivers/gpu/drm/i915/gt/uc/intel_guc.c b/drivers/gpu/drm/i915/gt/uc/intel_guc.c index 228070e31ef0..2c4ad4a65089 100644 --- a/drivers/gpu/drm/i915/gt/uc/intel_guc.c +++ b/drivers/gpu/drm/i915/gt/uc/intel_guc.c @@ -319,6 +319,14 @@ static u32 guc_ctl_wa_flags(struct intel_guc *guc) IS_DG2_GRAPHICS_STEP(gt->i915, G11, STEP_A0, STEP_B0)) flags |= GUC_WA_RCS_RESET_BEFORE_RC6; + /* + * Wa_22012727170:dg2_g10[a0-c0), dg2_g11[a0..) + * Wa_22012727685:dg2_g11[a0..) + */ + if (IS_DG2_GRAPHICS_STEP(gt->i915, G10, STEP_A0, STEP_C0) || + IS_DG2_GRAPHICS_STEP(gt->i915, G11, STEP_A0, STEP_FOREVER)) + flags |= GUC_WA_CONTEXT_ISOLATION; + return flags; } diff --git a/drivers/gpu/drm/i915/gt/uc/intel_guc_fwif.h b/drivers/gpu/drm/i915/gt/uc/intel_guc_fwif.h index e389a3a041a2..42cb7a9a6199 100644 --- a/drivers/gpu/drm/i915/gt/uc/intel_guc_fwif.h +++ b/drivers/gpu/drm/i915/gt/uc/intel_guc_fwif.h @@ -101,6 +101,7 @@ #define GUC_WA_GAM_CREDITS BIT(10) #define GUC_WA_DUAL_QUEUE BIT(11) #define GUC_WA_RCS_RESET_BEFORE_RC6 BIT(13) +#define GUC_WA_CONTEXT_ISOLATION BIT(15) #define GUC_WA_PRE_PARSER BIT(14) #define GUC_WA_HOLD_CCS_SWITCHOUT BIT(17) #define GUC_WA_POLLCS BIT(18) -- 2.35.1
