Hi all, Today's linux-next merge of the drm tree got a conflict in: drivers/gpu/drm/i915/gt/intel_gt.c between commit: 04aa64375f48 ("drm/i915: fix TLB invalidation for Gen12 video and compute engines") from Linus' tree and commit: 46c507f03a46 ("drm/i915/gt: Always use MCR functions on multicast registers") from the drm tree. I fixed it up (see below) and can carry the fix as necessary. This is now fixed as far as linux-next is concerned, but any non trivial conflicts should be mentioned to your upstream maintainer when your tree is submitted for merging. You may also want to consider cooperating with the maintainer of the conflicting tree to minimise any particularly complex conflicts. -- Cheers, Stephen Rothwell diff --cc drivers/gpu/drm/i915/gt/intel_gt.c index 7caa3412a244,0325f071046c..000000000000 --- a/drivers/gpu/drm/i915/gt/intel_gt.c +++ b/drivers/gpu/drm/i915/gt/intel_gt.c @@@ -1018,16 -1103,17 +1108,22 @@@ static void mmio_invalidate_full(struc if (!intel_engine_pm_is_awake(engine)) continue; - rb = get_reg_and_bit(engine, regs == gen8_regs, regs, num); - if (!i915_mmio_reg_offset(rb.reg)) - continue; - - if (GRAPHICS_VER(i915) == 12 && (engine->class == VIDEO_DECODE_CLASS || - engine->class == VIDEO_ENHANCEMENT_CLASS || - engine->class == COMPUTE_CLASS)) - rb.bit = _MASKED_BIT_ENABLE(rb.bit); - - intel_uncore_write_fw(uncore, rb.reg, rb.bit); + if (GRAPHICS_VER_FULL(i915) >= IP_VER(12, 50)) { + intel_gt_mcr_multicast_write_fw(gt, + xehp_regs[engine->class], + BIT(engine->instance)); + } else { + rb = get_reg_and_bit(engine, regs == gen8_regs, regs, num); + if (!i915_mmio_reg_offset(rb.reg)) + continue; + ++ if (GRAPHICS_VER(i915) == 12 && (engine->class == VIDEO_DECODE_CLASS || ++ engine->class == VIDEO_ENHANCEMENT_CLASS || ++ engine->class == COMPUTE_CLASS)) ++ rb.bit = _MASKED_BIT_ENABLE(rb.bit); ++ + intel_uncore_write_fw(uncore, rb.reg, rb.bit); + } awake |= engine->mask; }
