We also rename the enc_queue_init() function (in rockchip_vpu_drv.c) queue_init() since it will be used to initialize both type of queues. The implementation itself will be patched to support the decoding case when decoder support is added.

Right now the order doesn't matter, but if we want to have a valid default width/height on the non-coded/raw format side (src in case of encoders, dst in case of decoders), we need to reset those formats in the right order: first the coded-format side, then the other, such that width and height on the raw format side can be taken from the coded format. Let's provide a helper that will reset both formats and make sure this is done in the right order.

Two v4l2 interfaces are exposed, one for encoding and one for decoding, but a single m2m device is shared by them, so jobs are properly serialized. Signed-off-by: Ezequiel Garcia Signed-off-by: Boris Brezillon --- Changes from v2: * Use the common vb2/v4l2 implementation * Use strscpy instead of strlcpy. * Abstract vidioc v4l2 api implementations into generic code, creating helpers that can be used by the encoder and the decoder. * Only prevent S_FMT on the coded format queue, if the peer queue has buffers allocated. * Refactor the code, adding a buf_finish callback to rockchip_vpu_ctx. With this change, is_enc field is not needed. * Separate OUTPUT and CAPTURE queue ops (vb2_ops), and create common helpers that can be used by both. * Pass a no kernel mapping attribute on both ends of the decoder. --- .../media/rockchip/vpu/rk3399_vpu_hw.c | 19 ++ .../staging/media/rockchip/vpu/rockchip_vpu.h | 52 +++++- .../media/rockchip/vpu/rockchip_vpu_common.h | 46 +++++ .../media/rockchip/vpu/rockchip_vpu_drv.c | 164 ++++++++++++++---- .../media/rockchip/vpu/rockchip_vpu_v4l2.c | 9 +- 5 files changed, 251 insertions(+), 39 deletions(-) create mode 100644 drivers/staging/media/rockchip/vpu/rockchip_vpu_common.h diff --git a/drivers/staging/media/rockchip/vpu/rk3399_vpu_hw.c b/drivers/staging/media/rockchip/vpu/rk3399_vpu_hw.c index f4effad00605..87460fe179f5 100644 --- a/drivers/staging/media/rockchip/vpu/rk3399_vpu_hw.c +++ b/drivers/staging/media/rockchip/vpu/rk3399_vpu_hw.c @@ -74,6 +74,24 @@ static irqreturn_t rk3399_vepu_irq(int irq, void *dev_id) return IRQ_HANDLED; } +static irqreturn_t rk3399_vdpu_irq(int irq, void *dev_id) +{ + struct rockchip_vpu_dev *vpu = dev_id; + enum vb2_buffer_state state; + u32 status; + + status = vdpu_read(vpu, VDPU_REG_INTERRUPT); + state = (status & VDPU_REG_INTERRUPT_DEC_IRQ) ? + VB2_BUF_STATE_DONE : VB2_BUF_STATE_ERROR; + + vdpu_write(vpu, 0, VDPU_REG_INTERRUPT); + vdpu_write(vpu, 0, VDPU_REG_AXI_CTRL); + + rockchip_vpu_irq_done(vpu, 0, state); + + return IRQ_HANDLED; +} + static int rk3399_vpu_hw_init(struct rockchip_vpu_dev *vpu) { /* Bump ACLK to max. possible freq. to improve performance. */ @@ -114,6 +132,7 @@ const struct rockchip_vpu_variant rk3399_vpu_variant = { .codec = RK_VPU_CODEC_JPEG, .codec_ops = rk3399_vpu_codec_ops, .vepu_irq = rk3399_vepu_irq, + .vdpu_irq = rk3399_vdpu_irq, .init = rk3399_vpu_hw_init, .clk_names = {"aclk", "hclk"}, .num_clocks = 2 diff --git a/drivers/staging/media/rockchip/vpu/rockchip_vpu.h b/drivers/staging/media/rockchip/vpu/rockchip_vpu.h index ce0fb185c5f8..17bcfd302283 100644 --- a/drivers/staging/media/rockchip/vpu/rockchip_vpu.h +++ b/drivers/staging/media/rockchip/vpu/rockchip_vpu.h @@ -40,23 +40,31 @@ struct rockchip_vpu_codec_ops; * struct rockchip_vpu_variant - information about VPU hardware variant * * @enc_offset: Offset from VPU base to encoder registers. + * @dec_offset: Offset from VPU base to decoder registers. * @enc_fmts: Encoder formats. * @num_enc_fmts: Number of encoder formats. + * @dec_fmts: Decoder formats. + * @num_dec_fmts: Number of decoder formats. * @codec: Supported codecs * @codec_ops: Codec ops. * @init: Initialize hardware. * @vepu_irq: encoder interrupt handler + * @vdpu_irq: decoder interrupt handler * @clk_names: array of clock names * @num_clocks: number of clocks in the array */ struct rockchip_vpu_variant { unsigned int enc_offset; + unsigned int dec_offset; const struct rockchip_vpu_fmt *enc_fmts; unsigned int num_enc_fmts; + const struct rockchip_vpu_fmt *dec_fmts; + unsigned int num_dec_fmts; unsigned int codec; const struct rockchip_vpu_codec_ops *codec_ops; int (*init)(struct rockchip_vpu_dev *vpu); irqreturn_t (*vepu_irq)(int irq, void *priv); + irqreturn_t (*vdpu_irq)(int irq, void *priv); const char *clk_names[ROCKCHIP_VPU_MAX_CLOCKS]; int num_clocks; }; @@ -71,6 +79,16 @@ enum rockchip_vpu_codec_mode { RK_VPU_MODE_JPEG_ENC, }; +/** + * enum rockchip_vpu_type - device type, encoder or decoder + * @RK_VPU_ENCODER: The device is an encoder. + * @RK_VPU_DECODER: The device is a decoder. + */ +enum rockchip_vpu_type { + RK_VPU_ENCODER, + RK_VPU_DECODER, +}; + /* * struct rockchip_vpu_mc - media controller data * @@ -99,6 +117,7 @@ struct rockchip_vpu_mc { * @m2m_dev: mem2mem device associated to this device. * @mdev: media device associated to this device. * @vfd_enc: Video device for encoder. + * @vfd_dec: Video device for decoder. * @pdev: Pointer to VPU platform device. * @mc: Array of media controller topology structs * for encoder and decoder. @@ -107,6 +126,7 @@ struct rockchip_vpu_mc { * @clocks: Array of clock handles. * @base: Mapped address of VPU registers. * @enc_base: Mapped address of VPU encoder register for convenience. + * @dec_base: Mapped address of VPU decoder register for convenience. * @vpu_mutex: Mutex to synchronize V4L2 calls. * @irqlock: Spinlock to synchronize access to data structures * shared with interrupt handlers. @@ -118,12 +138,14 @@ struct rockchip_vpu_dev { struct v4l2_m2m_dev *m2m_dev; struct media_device mdev; struct video_device *vfd_enc; + struct video_device *vfd_dec; struct platform_device *pdev; struct rockchip_vpu_mc mc[2]; struct device *dev; struct clk_bulk_data clocks[ROCKCHIP_VPU_MAX_CLOCKS]; void __iomem *base; void __iomem *enc_base; + void __iomem *dec_base; struct mutex vpu_mutex; /* video_device lock */ spinlock_t irqlock; @@ -148,6 +170,9 @@ struct rockchip_vpu_dev { * @ctrl_handler: Control handler used to register controls. * @jpeg_quality: User-specified JPEG compression quality. * + * @buf_finish: Buffer finish.
