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 v4: * Remove vpu_common.h inclusion * Set ->requires_requests from s_fmt() instead of fixing it at queue creation time (suggested by Hans) Changes from v3: * Update things according to changes done in the patch introducing custom media controller support (Boris) * Move the rk3399 vdpu irq definition in the commit introducing MPGEG2 support on rk3399 * Fix media controller deregistration code (Jonas) 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. --- drivers/staging/media/rockchip/vpu/Kconfig | 1 + .../staging/media/rockchip/vpu/rockchip_vpu.h | 42 ++++- .../media/rockchip/vpu/rockchip_vpu_drv.c | 169 ++++++++++++++---- .../media/rockchip/vpu/rockchip_vpu_v4l2.c | 29 ++- 4 files changed, 203 insertions(+), 38 deletions(-) diff --git a/drivers/staging/media/rockchip/vpu/Kconfig b/drivers/staging/media/rockchip/vpu/Kconfig index fc54bbf6753d..842b003e08b8 100644 --- a/drivers/staging/media/rockchip/vpu/Kconfig +++ b/drivers/staging/media/rockchip/vpu/Kconfig @@ -3,6 +3,7 @@ config VIDEO_ROCKCHIP_VPU tristate "Rockchip VPU driver" depends on ARCH_ROCKCHIP || COMPILE_TEST depends on VIDEO_DEV && VIDEO_V4L2 && MEDIA_CONTROLLER + depends on MEDIA_CONTROLLER_REQUEST_API select VIDEOBUF2_DMA_CONTIG select VIDEOBUF2_VMALLOC select V4L2_MEM2MEM_DEV diff --git a/drivers/staging/media/rockchip/vpu/rockchip_vpu.h b/drivers/staging/media/rockchip/vpu/rockchip_vpu.h index 0d24fd257a2b..3d64f3e95c9b 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; }; @@ -112,12 +120,14 @@ rockchip_vpu_vdev_to_func(struct video_device *vdev) * @m2m_dev: mem2mem device associated to this device. * @mdev: media device associated to this device. * @encoder: encoder functionality. + * @decoder: decoder functionality. * @pdev: Pointer to VPU platform device. * @dev: Pointer to device for convenient logging using * dev_ macros. * @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. @@ -129,11 +139,13 @@ struct rockchip_vpu_dev { struct v4l2_m2m_dev *m2m_dev; struct media_device mdev; struct rockchip_vpu_func *encoder; + struct rockchip_vpu_func *decoder; struct platform_device *pdev; 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; @@ -158,6 +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.
