Hi Dave, Today's linux-next merge of the drm tree got a conflict in: drivers/gpu/drm/i915/gvt/cmd_parser.c between commit: 695fbc08d80f ("drm/i915/gvt: replace the gvt_err with gvt_vgpu_err") from the drm-intel-fixes tree and commit: 73dec95e6ba3 ("drm/i915: Emit to ringbuffer directly") 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/gvt/cmd_parser.c index 2b92cc8a7d1a,81076d8ec41a..000000000000 --- a/drivers/gpu/drm/i915/gvt/cmd_parser.c +++ b/drivers/gpu/drm/i915/gvt/cmd_parser.c @@@ -1673,8 -1644,8 +1673,8 @@@ static int perform_bb_shadow(struct par ret = copy_gma_to_hva(s->vgpu, s->vgpu->gtt.ggtt_mm, gma, gma + bb_size, dst); - if (ret) { + if (ret < 0) { - gvt_err("fail to copy guest ring buffer\n"); + gvt_vgpu_err("fail to copy guest ring buffer\n"); goto unmap_src; } @@@ -2668,26 -2633,23 +2665,24 @@@ static int shadow_workload_ring_buffer( /* head > tail --> copy head <-> top */ if (gma_head > gma_tail) { ret = copy_gma_to_hva(vgpu, vgpu->gtt.ggtt_mm, - gma_head, gma_top, - workload->shadow_ring_buffer_va); - if (ret) { + gma_head, gma_top, cs); + if (ret < 0) { + gvt_err("fail to copy guest ring buffer\n"); + gvt_vgpu_err("fail to copy guest ring buffer\n"); return ret; } - copy_len = gma_top - gma_head; + cs += ret / sizeof(u32); gma_head = workload->rb_start; } /* copy head or start <-> tail */ - ret = copy_gma_to_hva(vgpu, vgpu->gtt.ggtt_mm, - gma_head, gma_tail, - workload->shadow_ring_buffer_va + copy_len); - if (ret) { + ret = copy_gma_to_hva(vgpu, vgpu->gtt.ggtt_mm, gma_head, gma_tail, cs); + if (ret < 0) { - gvt_err("fail to copy guest ring buffer\n"); + gvt_vgpu_err("fail to copy guest ring buffer\n"); return ret; } - ring->tail += workload->rb_len; - intel_ring_advance(ring); + cs += ret / sizeof(u32); + intel_ring_advance(workload->req, cs); return 0; } @@@ -2743,8 -2703,8 +2738,8 @@@ static int shadow_indirect_ctx(struct i wa_ctx->workload->vgpu->gtt.ggtt_mm, guest_gma, guest_gma + ctx_size, map); - if (ret) { + if (ret < 0) { - gvt_err("fail to copy guest indirect ctx\n"); + gvt_vgpu_err("fail to copy guest indirect ctx\n"); goto unmap_src; } -- To unsubscribe from this list: send the line "unsubscribe linux-next" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
