Avoid overriding those fields in this case. Signed-off-by: Boris Brezillon --- Hello Hans, The sizeimage/bytesperline check on !MPLANE formats is still not 100% sure, as custom bytesperline might induce bigger sizeimage than what we calculate. I tried implementing something smarter taking the per-component plane bpp + hdiv param as we discussed the other day but decided to step back after realizing the per-component plane macro block might also differ at least in theory (not sure that's true in practice) and that has an impact on bytesperline too. Let me know how you want to handle that case.

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 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 9a6fc1378242..f645c19f10d1 100644 --- a/drivers/staging/media/rockchip/vpu/Kconfig +++ b/drivers/staging/media/rockchip/vpu/Kconfig @@ -2,6 +2,7 @@ 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.
