Hi Arun, This patch sets looks very good. Please check my comments below.
> From: Arun Kumar K [mailto:arun...@samsung.com] > > Firmware version v7 is mostly similar to v6 in terms of hardware > specific controls and commands. So the hardware specific opr_v6 and > cmd_v6 are re-used for v7 also. This patch updates the v6 files to > handle v7 version also. > > Signed-off-by: Arun Kumar K <arun...@samsung.com> > --- > drivers/media/platform/s5p-mfc/s5p_mfc_enc.c | 11 ++++- > drivers/media/platform/s5p-mfc/s5p_mfc_opr_v6.c | 53 > +++++++++++++++++++---- > 2 files changed, 53 insertions(+), 11 deletions(-) > > diff --git a/drivers/media/platform/s5p-mfc/s5p_mfc_enc.c > b/drivers/media/platform/s5p-mfc/s5p_mfc_enc.c > index f734ccc..dd57b06 100644 > --- a/drivers/media/platform/s5p-mfc/s5p_mfc_enc.c > +++ b/drivers/media/platform/s5p-mfc/s5p_mfc_enc.c > @@ -1663,8 +1663,15 @@ static int s5p_mfc_queue_setup(struct vb2_queue > *vq, > if (*buf_count > MFC_MAX_BUFFERS) > *buf_count = MFC_MAX_BUFFERS; > > - psize[0] = ctx->luma_size; > - psize[1] = ctx->chroma_size; > + if (IS_MFCV7(dev)) { > + /* MFCv7 needs pad bytes for input YUV */ > + psize[0] = ctx->luma_size + 256; > + psize[1] = ctx->chroma_size + 128; Here, I would add some define name to avoid magic number. Secondly, why wasn't this padding added in s5p_mfc_enc_calc_src_size_v6/v7? enc_calc_src_size is called in s_fmt, so it seems the best place to adjust buffer/plane sizes. > + } else { > + psize[0] = ctx->luma_size; > + psize[1] = ctx->chroma_size; > + } > + > if (IS_MFCV6_PLUS(dev)) { > allocators[0] = > ctx->dev->alloc_ctx[MFC_BANK1_ALLOC_CTX]; > diff --git a/drivers/media/platform/s5p-mfc/s5p_mfc_opr_v6.c > b/drivers/media/platform/s5p-mfc/s5p_mfc_opr_v6.c > index 7d4c5e1..7145ae5 100644 > --- a/drivers/media/platform/s5p-mfc/s5p_mfc_opr_v6.c > +++ b/drivers/media/platform/s5p-mfc/s5p_mfc_opr_v6.c > @@ -80,6 +80,7 @@ static int s5p_mfc_alloc_codec_buffers_v6(struct > s5p_mfc_ctx *ctx) > ctx->tmv_buffer_size = S5P_FIMV_NUM_TMV_BUFFERS_V6 * > ALIGN(S5P_FIMV_TMV_BUFFER_SIZE_V6(mb_width, > mb_height), > S5P_FIMV_TMV_BUFFER_ALIGN_V6); > + > ctx->luma_dpb_size = ALIGN((mb_width * mb_height) * > S5P_FIMV_LUMA_MB_TO_PIXEL_V6, > S5P_FIMV_LUMA_DPB_BUFFER_ALIGN_V6); > @@ -112,10 +113,18 @@ static int s5p_mfc_alloc_codec_buffers_v6(struct > s5p_mfc_ctx *ctx) > (ctx->mv_count * ctx->mv_size); > break; > case S5P_MFC_CODEC_MPEG4_DEC: > - ctx->scratch_buf_size = > - S5P_FIMV_SCRATCH_BUF_SIZE_MPEG4_DEC_V6( > - mb_width, > - mb_height); > + if (IS_MFCV7(dev)) { > + ctx->scratch_buf_size = > + S5P_FIMV_SCRATCH_BUF_SIZE_MPEG4_DEC_V7( > + mb_width, > + mb_height); > + } else { > + ctx->scratch_buf_size = > + S5P_FIMV_SCRATCH_BUF_SIZE_MPEG4_DEC_V6( > + mb_width, > + mb_height); > + } > + > ctx->scratch_buf_size = ALIGN(ctx->scratch_buf_size, > S5P_FIMV_SCRATCH_BUFFER_ALIGN_V6); > ctx->bank1.size = ctx->scratch_buf_size; @@ -453,8 +462,13 > @@ static void s5p_mfc_set_enc_frame_buffer_v6(struct s5p_mfc_ctx *ctx, > { > struct s5p_mfc_dev *dev = ctx->dev; > > - WRITEL(y_addr, S5P_FIMV_E_SOURCE_LUMA_ADDR_V6); /* 256B align */ > - WRITEL(c_addr, S5P_FIMV_E_SOURCE_CHROMA_ADDR_V6); > + if (IS_MFCV7(dev)) { > + WRITEL(y_addr, S5P_FIMV_E_SOURCE_FIRST_ADDR_V7); > + WRITEL(c_addr, S5P_FIMV_E_SOURCE_SECOND_ADDR_V7); > + } else { > + WRITEL(y_addr, S5P_FIMV_E_SOURCE_LUMA_ADDR_V6); > + WRITEL(c_addr, S5P_FIMV_E_SOURCE_CHROMA_ADDR_V6); > + } > > mfc_debug(2, "enc src y buf addr: 0x%08lx\n", y_addr); > mfc_debug(2, "enc src c buf addr: 0x%08lx\n", c_addr); @@ -466,8 > +480,13 @@ static void s5p_mfc_get_enc_frame_buffer_v6(struct > s5p_mfc_ctx *ctx, > struct s5p_mfc_dev *dev = ctx->dev; > unsigned long enc_recon_y_addr, enc_recon_c_addr; > > - *y_addr = READL(S5P_FIMV_E_ENCODED_SOURCE_LUMA_ADDR_V6); > - *c_addr = READL(S5P_FIMV_E_ENCODED_SOURCE_CHROMA_ADDR_V6); > + if (IS_MFCV7(dev)) { > + *y_addr = READL(S5P_FIMV_E_ENCODED_SOURCE_FIRST_ADDR_V7); > + *c_addr = READL(S5P_FIMV_E_ENCODED_SOURCE_SECOND_ADDR_V7); > + } else { > + *y_addr = READL(S5P_FIMV_E_ENCODED_SOURCE_LUMA_ADDR_V6); > + *c_addr = READL(S5P_FIMV_E_ENCODED_SOURCE_CHROMA_ADDR_V6); > + } > > enc_recon_y_addr = READL(S5P_FIMV_E_RECON_LUMA_DPB_ADDR_V6); > enc_recon_c_addr = READL(S5P_FIMV_E_RECON_CHROMA_DPB_ADDR_V6); > @@ -1166,6 +1185,12 @@ static int s5p_mfc_init_decode_v6(struct > s5p_mfc_ctx *ctx) > reg |= (0x1 << S5P_FIMV_D_OPT_DDELAY_EN_SHIFT_V6); > WRITEL(ctx->display_delay, S5P_FIMV_D_DISPLAY_DELAY_V6); > } > + > + if (IS_MFCV7(dev)) { > + WRITEL(reg, S5P_FIMV_D_DEC_OPTIONS_V6); > + reg = 0; > + } > + > /* Setup loop filter, for decoding this is only valid for MPEG4 > */ > if (ctx->codec_mode == S5P_MFC_CODEC_MPEG4_DEC) { > mfc_debug(2, "Set loop filter to: %d\n", @@ -1176,7 > +1201,10 @@ static int s5p_mfc_init_decode_v6(struct s5p_mfc_ctx *ctx) > if (ctx->dst_fmt->fourcc == V4L2_PIX_FMT_NV12MT_16X16) > reg |= (0x1 << S5P_FIMV_D_OPT_TILE_MODE_SHIFT_V6); > > - WRITEL(reg, S5P_FIMV_D_DEC_OPTIONS_V6); > + if (IS_MFCV7(dev)) > + WRITEL(reg, S5P_FIMV_D_INIT_BUFFER_OPTIONS_V7); > + else > + WRITEL(reg, S5P_FIMV_D_DEC_OPTIONS_V6); > > /* 0: NV12(CbCr), 1: NV21(CrCb) */ > if (ctx->dst_fmt->fourcc == V4L2_PIX_FMT_NV21M) @@ -1184,6 > +1212,7 @@ static int s5p_mfc_init_decode_v6(struct s5p_mfc_ctx *ctx) > else > WRITEL(0x0, S5P_FIMV_PIXEL_FORMAT_V6); > > + > /* sei parse */ > WRITEL(ctx->sei_fp_parse & 0x1, S5P_FIMV_D_SEI_ENABLE_V6); > > @@ -1254,6 +1283,12 @@ static int s5p_mfc_init_encode_v6(struct > s5p_mfc_ctx *ctx) > return -EINVAL; > } > > + /* Set stride lengths */ > + if (IS_MFCV7(dev)) { > + WRITEL(ctx->img_width, S5P_FIMV_E_SOURCE_FIRST_STRIDE_V7); > + WRITEL(ctx->img_width, S5P_FIMV_E_SOURCE_SECOND_STRIDE_V7); > + } > + > WRITEL(ctx->inst_no, S5P_FIMV_INSTANCE_ID_V6); > s5p_mfc_hw_call(dev->mfc_cmds, cmd_host2risc, dev, > S5P_FIMV_CH_SEQ_HEADER_V6, NULL); > -- > 1.7.9.5 Best wishes, -- Kamil Debski Linux Kernel Developer Samsung R&D Institute Poland -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
