For render/compute engines, the part of the context images are nearly the same, although the layout had a very slight change --- one POSH register was removed and the placement of some LRI/noops adjusted slightly to compensate. v2: - Dg2, mtl xcs offsets slightly vary. Use a seperate offsets array(Bala) - Drop unused registers in mtl rcs offsets.(Bala) Bspec: 46261, 46260, 45585 Cc: Balasubramani Vivekanandan Signed-off-by: Matt Roper Signed-off-by: Radhakrishna Sripada --- drivers/gpu/drm/i915/gt/intel_lrc.c | 81 ++++++++++++++++++++++++++++- 1 file changed, 79 insertions(+), 2 deletions(-) diff --git a/drivers/gpu/drm/i915/gt/intel_lrc.c b/drivers/gpu/drm/i915/gt/intel_lrc.c index 070cec4ff8a4..ecb030ee39cd 100644 --- a/drivers/gpu/drm/i915/gt/intel_lrc.c +++ b/drivers/gpu/drm/i915/gt/intel_lrc.c @@ -264,6 +264,38 @@ static const u8 dg2_xcs_offsets[] = { END }; +static const u8 mtl_xcs_offsets[] = { + NOP(1), + LRI(13, POSTED), + REG16(0x244), + REG(0x034), + REG(0x030), + REG(0x038), + REG(0x03c), + REG(0x168), + REG(0x140), + REG(0x110), + REG(0x1c0), + REG(0x1c4), + REG(0x1c8), + REG(0x180), + REG16(0x2b4), + + NOP(1), + LRI(9, POSTED), + REG16(0x3a8), + REG16(0x28c), + REG16(0x288), + REG16(0x284), + REG16(0x280), + REG16(0x27c), + REG16(0x278), + REG16(0x274), + REG16(0x270), + + END +}; + static const u8 gen8_rcs_offsets[] = { NOP(1), LRI(14, POSTED), @@ -606,6 +638,47 @@ static const u8 dg2_rcs_offsets[] = { END }; +static const u8 mtl_rcs_offsets[] = { + NOP(1), + LRI(13, POSTED), + REG16(0x244), + REG(0x034), + REG(0x030), + REG(0x038), + REG(0x03c), + REG(0x168), + REG(0x140), + REG(0x110), + REG(0x1c0), + REG(0x1c4), + REG(0x1c8), + REG(0x180), + REG16(0x2b4), + + NOP(1), + LRI(9, POSTED), + REG16(0x3a8), + REG16(0x28c), + REG16(0x288), + REG16(0x284), + REG16(0x280), + REG16(0x27c), + REG16(0x278), + REG16(0x274), + REG16(0x270), + + NOP(2), + LRI(2, POSTED), + REG16(0x5a8), + REG16(0x5ac), + + NOP(6), + LRI(1, 0), + REG(0x0c8), + + END +}; + #undef END #undef REG16 #undef REG @@ -624,7 +697,9 @@ static const u8 *reg_offsets(const struct intel_engine_cs *engine) !intel_engine_has_relative_mmio(engine)); if (engine->flags & I915_ENGINE_HAS_RCS_REG_STATE) { - if (GRAPHICS_VER_FULL(engine->i915) >= IP_VER(12, 55)) + if (GRAPHICS_VER_FULL(engine->i915) >= IP_VER(12, 70)) + return mtl_rcs_offsets; + else if (GRAPHICS_VER_FULL(engine->i915) >= IP_VER(12, 55)) return dg2_rcs_offsets; else if (GRAPHICS_VER_FULL(engine->i915) >= IP_VER(12, 50)) return xehp_rcs_offsets; @@ -637,7 +712,9 @@ static const u8 *reg_offsets(const struct intel_engine_cs *engine) else return gen8_rcs_offsets; } else { - if (GRAPHICS_VER_FULL(engine->i915) >= IP_VER(12, 55)) + if (GRAPHICS_VER_FULL(engine->i915) >= IP_VER(12, 70)) + return mtl_xcs_offsets; + else if (GRAPHICS_VER_FULL(engine->i915) >= IP_VER(12, 55)) return dg2_xcs_offsets; else if (GRAPHICS_VER(engine->i915) >= 12) return gen12_xcs_offsets;
