This introduces support for HEVC/H.265 to the Cedrus VPU driver, with
both uni-directional and bi-directional prediction modes supported.

Field-coded (interlaced) pictures, custom quantization matrices and
10-bit output are not supported at this point.

Having some information on where this is coming from would be useful.

Since the data pointer is pretty much an opaque structure, you should
have a void pointer here, that would avoid the type casting you're
doing when calling that function.

You can only pass the run and slice_params pointers to that function.

+
+	cedrus_write(dev, VE_DEC_H265_OUTPUT_FRAME_IDX, output_pic_list_index);
+
+	/* Reference picture list 0 (for P/B frames). */
+	if (slice_params->slice_type != V4L2_HEVC_SLICE_TYPE_I) {
+		cedrus_h265_ref_pic_list_write(dev, slice_params->ref_idx_l0,
+			slice_params->num_ref_idx_l0_active_minus1 + 1,
+			slice_params->dpb, slice_params->num_active_dpb_entries,
+			VE_DEC_H265_SRAM_OFFSET_REF_PIC_LIST0);
+

slice_params is enough.

+		if (pps->weighted_pred_flag || pps->weighted_bipred_flag)
+			cedrus_h265_pred_weight_write(dev,
+				pred_weight_table->delta_luma_weight_l0,
+				pred_weight_table->luma_offset_l0,
+				pred_weight_table->delta_chroma_weight_l0,
+				pred_weight_table->chroma_offset_l0,
+				slice_params->num_ref_idx_l0_active_minus1 + 1,
+				VE_DEC_H265_SRAM_OFFSET_PRED_WEIGHT_LUMA_L0,
+				VE_DEC_H265_SRAM_OFFSET_PRED_WEIGHT_CHROMA_L0);

Ditto, that function should only take the pred_weight_table and
slice_params pointers

+	}
+
+	/* Reference picture list 1 (for B frames). */
+	if (slice_params->slice_type == V4L2_HEVC_SLICE_TYPE_B) {
+		cedrus_h265_ref_pic_list_write(dev, slice_params->ref_idx_l1,
+			slice_params->num_ref_idx_l1_active_minus1 + 1,
+			slice_params->dpb,
+			slice_params->num_active_dpb_entries,
+			VE_DEC_H265_SRAM_OFFSET_REF_PIC_LIST1);
+
+		if (pps->weighted_bipred_flag)
+			cedrus_h265_pred_weight_write(dev,
+				pred_weight_table->delta_luma_weight_l1,
+				pred_weight_table->luma_offset_l1,
+				pred_weight_table->delta_chroma_weight_l1,
+				pred_weight_table->chroma_offset_l1,
+				slice_params->num_ref_idx_l1_active_minus1 + 1,
+				VE_DEC_H265_SRAM_OFFSET_PRED_WEIGHT_LUMA_L1,
+				VE_DEC_H265_SRAM_OFFSET_PRED_WEIGHT_CHROMA_L1);
+	}

Ditto

Looks good otherwise, thanks!
