This is only used by GRAPHICS_VER == 6 and GRAPHICS_VER == 7. All other recent platforms do not depend on this field, so it doesn't make much sense to keep it generic like that. Instead, just do a mapping from engine class to HW ID in the single place that is needed. v2: use macros with the direct register address instead of calculating from the legacy HW_ID (Matt Roper) Signed-off-by: Lucas De Marchi <lucas.demarchi@xxxxxxxxx> Reviewed-by: Matt Roper <matthew.d.roper@xxxxxxxxx> --- drivers/gpu/drm/i915/gt/intel_engine_cs.c | 6 ------ drivers/gpu/drm/i915/gt/intel_engine_types.h | 10 +--------- drivers/gpu/drm/i915/i915_reg.h | 11 ++++++++++- 3 files changed, 11 insertions(+), 16 deletions(-) diff --git a/drivers/gpu/drm/i915/gt/intel_engine_cs.c b/drivers/gpu/drm/i915/gt/intel_engine_cs.c index 9c8cba1c6cd1..876efa29b123 100644 --- a/drivers/gpu/drm/i915/gt/intel_engine_cs.c +++ b/drivers/gpu/drm/i915/gt/intel_engine_cs.c @@ -42,7 +42,6 @@ #define MAX_MMIO_BASES 3 struct engine_info { - u8 gen6_hw_id; u8 class; u8 instance; /* mmio bases table *must* be sorted in reverse graphics_ver order */ @@ -54,7 +53,6 @@ struct engine_info { static const struct engine_info intel_engines[] = { [RCS0] = { - .gen6_hw_id = RCS0_HW, .class = RENDER_CLASS, .instance = 0, .mmio_bases = { @@ -62,7 +60,6 @@ static const struct engine_info intel_engines[] = { }, }, [BCS0] = { - .gen6_hw_id = BCS0_HW, .class = COPY_ENGINE_CLASS, .instance = 0, .mmio_bases = { @@ -70,7 +67,6 @@ static const struct engine_info intel_engines[] = { }, }, [VCS0] = { - .gen6_hw_id = VCS0_HW, .class = VIDEO_DECODE_CLASS, .instance = 0, .mmio_bases = { @@ -102,7 +98,6 @@ static const struct engine_info intel_engines[] = { }, }, [VECS0] = { - .gen6_hw_id = VECS0_HW, .class = VIDEO_ENHANCEMENT_CLASS, .instance = 0, .mmio_bases = { @@ -290,7 +285,6 @@ static int intel_engine_setup(struct intel_gt *gt, enum intel_engine_id id) engine->i915 = i915; engine->gt = gt; engine->uncore = gt->uncore; - engine->gen6_hw_id = info->gen6_hw_id; guc_class = engine_class_to_guc_class(info->class); engine->guc_id = MAKE_GUC_ID(guc_class, info->instance); engine->mmio_base = __engine_mmio_base(i915, info->mmio_bases); diff --git a/drivers/gpu/drm/i915/gt/intel_engine_types.h b/drivers/gpu/drm/i915/gt/intel_engine_types.h index 266422d8d1b1..a4111813f993 100644 --- a/drivers/gpu/drm/i915/gt/intel_engine_types.h +++ b/drivers/gpu/drm/i915/gt/intel_engine_types.h @@ -28,14 +28,7 @@ #include "intel_wakeref.h" #include "intel_workarounds_types.h" -/* Legacy HW Engine ID */ - -#define RCS0_HW 0 -#define VCS0_HW 1 -#define BCS0_HW 2 -#define VECS0_HW 3 - -/* Gen11+ HW Engine class + instance */ +/* HW Engine class + instance */ #define RENDER_CLASS 0 #define VIDEO_DECODE_CLASS 1 #define VIDEO_ENHANCEMENT_CLASS 2 @@ -268,7 +261,6 @@ struct intel_engine_cs { intel_engine_mask_t mask; - u8 gen6_hw_id; u8 class; u8 instance; diff --git a/drivers/gpu/drm/i915/i915_reg.h b/drivers/gpu/drm/i915/i915_reg.h index 8e1392028184..3718da619d90 100644 --- a/drivers/gpu/drm/i915/i915_reg.h +++ b/drivers/gpu/drm/i915/i915_reg.h @@ -2572,7 +2572,16 @@ static inline bool i915_mmio_reg_valid(i915_reg_t reg) #define ARB_MODE_BWGTLB_DISABLE (1 << 9) #define ARB_MODE_SWIZZLE_BDW (1 << 1) #define RENDER_HWS_PGA_GEN7 _MMIO(0x04080) -#define RING_FAULT_REG(engine) _MMIO(0x4094 + 0x100 * (engine)->gen6_hw_id) + +#define _RING_FAULT_REG_RCS 0x4094 +#define _RING_FAULT_REG_VCS 0x4194 +#define _RING_FAULT_REG_BCS 0x4294 +#define _RING_FAULT_REG_VECS 0x4394 +#define RING_FAULT_REG(engine) _MMIO(_PICK((engine)->class, \ + _RING_FAULT_REG_RCS, \ + _RING_FAULT_REG_VCS, \ + _RING_FAULT_REG_VECS, \ + _RING_FAULT_REG_BCS)) #define GEN8_RING_FAULT_REG _MMIO(0x4094) #define GEN12_RING_FAULT_REG _MMIO(0xcec4) #define GEN8_RING_FAULT_ENGINE_ID(x) (((x) >> 12) & 0x7) -- 2.31.1
