The driver is responsible for building a JPEG compliant bitstream and placing the entropy-encoded scan in it. Right now the driver uses a bounce buffer for the hardware to output the raw scan to. In commit e765dba11ec2 ("hantro: Move hantro_enc_buf_finish to JPEG codec_ops.done"), the code that copies the raw scan from the bounce buffer to the capture buffer was moved, but was only hooked up for the Hantro H1 (then RK3288) variant. The RK3399 variant was broken, producing a JPEG bitstream without the scan, and the capture buffer's .bytesused field unset. Fix this by duplicating the code that is executed when the JPEG encoder finishes encoding a frame. As the encoded length is read back from hardware, and the variants having different register layouts, the code is duplicated rather than shared.

This was then forward-ported to mainline (name and filename changes) and compile tested only. --- .../staging/media/hantro/hantro_h1_jpeg_enc.c | 2 +- drivers/staging/media/hantro/hantro_hw.h | 3 ++- .../media/hantro/rockchip_vpu2_hw_jpeg_enc.c | 17 +++++++++++++++++ drivers/staging/media/hantro/rockchip_vpu_hw.c | 5 +++-- 4 files changed, 23 insertions(+), 4 deletions(-) diff --git a/drivers/staging/media/hantro/hantro_h1_jpeg_enc.c b/drivers/staging/media/hantro/hantro_h1_jpeg_enc.c index 56cf261a8e95..9cd713c02a45 100644 --- a/drivers/staging/media/hantro/hantro_h1_jpeg_enc.c +++ b/drivers/staging/media/hantro/hantro_h1_jpeg_enc.c @@ -140,7 +140,7 @@ int hantro_h1_jpeg_enc_run(struct hantro_ctx *ctx) return 0; } -void hantro_jpeg_enc_done(struct hantro_ctx *ctx) +void hantro_h1_jpeg_enc_done(struct hantro_ctx *ctx) { struct hantro_dev *vpu = ctx->dev; u32 bytesused = vepu_read(vpu, H1_REG_STR_BUF_LIMIT) / 8; diff --git a/drivers/staging/media/hantro/hantro_hw.h b/drivers/staging/media/hantro/hantro_hw.h index 267a6d33a47b..60d4602d33ed 100644 --- a/drivers/staging/media/hantro/hantro_hw.h +++ b/drivers/staging/media/hantro/hantro_hw.h @@ -239,7 +239,8 @@ int hantro_h1_jpeg_enc_run(struct hantro_ctx *ctx); int rockchip_vpu2_jpeg_enc_run(struct hantro_ctx *ctx); int hantro_jpeg_enc_init(struct hantro_ctx *ctx); void hantro_jpeg_enc_exit(struct hantro_ctx *ctx); -void hantro_jpeg_enc_done(struct hantro_ctx *ctx); +void hantro_h1_jpeg_enc_done(struct hantro_ctx *ctx); +void rockchip_vpu2_jpeg_enc_done(struct hantro_ctx *ctx); dma_addr_t hantro_h264_get_ref_buf(struct hantro_ctx *ctx, unsigned int dpb_idx); diff --git a/drivers/staging/media/hantro/rockchip_vpu2_hw_jpeg_enc.c b/drivers/staging/media/hantro/rockchip_vpu2_hw_jpeg_enc.c index 991213ce1610..5d9ff420f0b5 100644 --- a/drivers/staging/media/hantro/rockchip_vpu2_hw_jpeg_enc.c +++ b/drivers/staging/media/hantro/rockchip_vpu2_hw_jpeg_enc.c @@ -171,3 +171,20 @@ int rockchip_vpu2_jpeg_enc_run(struct hantro_ctx *ctx) return 0; } + +void rockchip_vpu2_jpeg_enc_done(struct hantro_ctx *ctx) +{ + struct hantro_dev *vpu = ctx->dev; + u32 bytesused = vepu_read(vpu, VEPU_REG_STR_BUF_LIMIT) / 8; + struct vb2_v4l2_buffer *dst_buf = hantro_get_dst_buf(ctx); + + /* + * TODO: Rework the JPEG encoder to eliminate the need + * for a bounce buffer. + */ + memcpy(vb2_plane_vaddr(&dst_buf->vb2_buf, 0) + + ctx->vpu_dst_fmt->header_size, + ctx->jpeg_enc.bounce_buffer.cpu, bytesused); + vb2_set_plane_payload(&dst_buf->vb2_buf, 0, + ctx->vpu_dst_fmt->header_size + bytesused); +} diff --git a/drivers/staging/media/hantro/rockchip_vpu_hw.c b/drivers/staging/media/hantro/rockchip_vpu_hw.c index d4f52957cc53..0c22039162a0 100644 --- a/drivers/staging/media/hantro/rockchip_vpu_hw.c +++ b/drivers/staging/media/hantro/rockchip_vpu_hw.c @@ -343,7 +343,7 @@ static const struct hantro_codec_ops rk3066_vpu_codec_ops[] = { .run = hantro_h1_jpeg_enc_run, .reset = rockchip_vpu1_enc_reset, .init = hantro_jpeg_enc_init, - .done = hantro_jpeg_enc_done, + .done = hantro_h1_jpeg_enc_done, .exit = hantro_jpeg_enc_exit, }, [HANTRO_MODE_H264_DEC] = { @@ -371,7 +371,7 @@ static const struct hantro_codec_ops rk3288_vpu_codec_ops[] = { .run = hantro_h1_jpeg_enc_run, .reset = rockchip_vpu1_enc_reset, .init = hantro_jpeg_enc_init, - .done = hantro_jpeg_enc_done, + .done = hantro_h1_jpeg_enc_done, .exit = hantro_jpeg_enc_exit, }, [HANTRO_MODE_H264_DEC] = { @@ -399,6 +399,7 @@ static const struct hantro_codec_ops rk3399_vpu_codec_ops[] = { .run = rockchip_vpu2_jpeg_enc_run, .reset = rockchip_vpu2_enc_reset, .init = hantro_jpeg_enc_init, + .done = rockchip_vpu2_jpeg_enc_done, .exit = hantro_jpeg_enc_exit, }, [HANTRO_MODE_H264_DEC] = {
