==============
Introduction
==============
The purpose of this series is to add the driver for video codec hw embedded in the Mediatek's MT8173 SoCs.
Mediatek Video Codec is able to handle video encoding of in a range of formats.
This patch series also include VPU driver. Mediatek Video Codec driver rely on VPU driver to load,
communicate with VPU.
Internally the driver uses videobuf2 framework and MTK IOMMU and MTK SMI both have been merged in v4.6-rc1.
==================
Device interface
==================
In principle the driver bases on v4l2 memory-to-memory framework:
it provides a single video node and each opened file handle gets its own private context with separate
buffer queues. Each context consist of 2 buffer queues: OUTPUT (for source buffers, i.e. raw video
frames) and CAPTURE (for destination buffers, i.e. encoded video frames).
==============================
VPU (Video Processor Unit)
==============================
The VPU driver for hw video codec embedded in Mediatek's MT8173 SOCs.
It is able to handle video decoding/encoding in a range of formats.
The driver provides with VPU firmware download, memory management and the communication interface between CPU and VPU.
For VPU initialization, it will create virtual memory for CPU access and physical address for VPU hw device access.
When a decode/encode instance opens a device node, vpu driver will download vpu firmware to the device.
A decode/encode instant will decode/encode a frame using VPU interface to interrupt vpu to handle decoding/encoding jobs.
Please have a look at the code and comments will be very much appreciated.
Change in v9:
1. Rename idx in mtk_vcodec_ctx to id and curr_max_idx in mtk_vcodec_dev to id_counter.
2. Refine fops_vcodec_open
VPU part
Merge Julia Lawall's fixes[1][2] to "[PATCH v9 2/8] [media] VPU: mediatek: support Mediatek VPU"
[1][PATCH] VPU: mediatek: fix simple_open.cocci warnings
[2][PATCH] VPU: mediatek: fix platform_no_drv_owner.cocci warnings
Change in v8:
1. Refine indentation
2. Refine colorspace information process vidioc_try_fmt_vid_out_mplane
3. Remove instance_mask in mtk_vcodec_dev, use curr_max_idx for instance index
4. Use kzalloc to allocate ctx
5. Refine fops_vcodec_open
VPU Part
1. Refine vpu_load_firmware
Change in v7:
1. Rebase against the master branch of git://linuxtv.org/media_tree.git
2. Add ycbcr_enc, quantization and xfer_func in try_fmt, g_fmt, s_fmt
3. Merge h264_enc and vp8_enc to venc directory
Change in v6:
1. Add synchronization access protect between irq handler and work thread
2. Add DMA_ATTR_ALLOC_SINGLE_PAGES support
3. S_FMT will return coded_width, coded_height, so user space could allocate correct size memory that HW required
4. merge h264/vp8 enc ap and md32 ipi msg
5. separate h264/vp8 enc gop_size and intra_period handle
6. remove sizeimage relative code in work buffer function
7. Refine makefile to build as an module
8. Code clean up
VPU Part
1. export symbols for building VPU as an module
2. change function from "wait_event_interruptible_timeout" to "wait_event_timeout" since
CPU needs to wait for ACK from VPU even if it was interrupted by a signal

Change in v3:
1.Refine code to pass v4l2-compliance test, now it still has 2 issues 2.Refine code according to latest MTK
IOMMU patches[1] 3.Remove MFC51 specific CIDs and add MTK specific CIDs for for keyframe and
skip I-frame
4.Refine code according to review comments
Below is the v1.6 version v4l2-compliance report for the mt8173 encoder driver.
Now there are still 2 test fail in v1.6.
For VIDIOC_REQBUFS/CREATE_BUFS/QUERYBUF, we directly use v4l2_m2m_ioctl_* functions, but it still
fail. It pass in kernel 3.18 but fail in kernel 4.4.
We will try v1.8 in next version.
VIDIOC_EXPBUF is becuase we support all three memory types VB2_DMABUF, VB2_MMAP and VB2_USERPTR.
VIDIOC_EXPBUF only allowed when only VB2_MMAP supported.

Introduction
==============
The purpose of this series is to add the driver for video codec hw embedded in the Mediatek's MT8173 SoCs.
Mediatek Video Codec is able to handle video encoding of in a range of formats.
This patch series also include VPU driver. Mediatek Video Codec driver rely on VPU driver to load,
communicate with VPU.
Internally the driver uses videobuf2 framework and MTK IOMMU and MTK SMI both have been merged in v4.6-rc1.
==================
Device interface
==================
In principle the driver bases on v4l2 memory-to-memory framework:
it provides a single video node and each opened file handle gets its own private context with separate
buffer queues. Each context consist of 2 buffer queues: OUTPUT (for source buffers, i.e. raw video
frames) and CAPTURE (for destination buffers, i.e. encoded video frames).
==============================
VPU (Video Processor Unit)
==============================
The VPU driver for hw video codec embedded in Mediatek's MT8173 SOCs.
It is able to handle video decoding/encoding in a range of formats.
The driver provides with VPU firmware download, memory management and the communication interface between CPU and VPU.
For VPU initialization, it will create virtual memory for CPU access and physical address for VPU hw device access.
When a decode/encode instance opens a device node, vpu driver will download vpu firmware to the device.
A decode/encode instant will decode/encode a frame using VPU interface to interrupt vpu to handle decoding/encoding jobs.
Please have a look at the code and comments will be very much appreciated.
Change in v9:
1. Rename idx in mtk_vcodec_ctx to id and curr_max_idx in mtk_vcodec_dev to id_counter.
2. Refine fops_vcodec_open
VPU part
Merge Julia Lawall's fixes[1][2] to "[PATCH v9 2/8] [media] VPU: mediatek: support Mediatek VPU"

Change in v7:
1. Rebase against the master branch of git://linuxtv.org/media_tree.git
2. Add ycbcr_enc, quantization and xfer_func in try_fmt, g_fmt, s_fmt
3. Merge h264_enc and vp8_enc to venc directory
Change in v6:
1. Add synchronization access protect between irq handler and work thread
2. Add DMA_ATTR_ALLOC_SINGLE_PAGES support
3. S_FMT will return coded_width, coded_height, so user space could allocate correct size memory that HW required

8. Code clean up
VPU Part
1. export symbols for building VPU as an module
2. change function from "wait_event_interruptible_timeout" to "wait_event_timeout" since
CPU needs to wait for ACK from VPU even if it was interrupted by a signal

Change in v3:
1.Refine code to pass v4l2-compliance test, now it still has 2 issues 2.Refine code according to latest MTK
IOMMU patches[1] 3.Remove MFC51 specific CIDs and add MTK specific CIDs for for keyframe and
skip I-frame
4.Refine code according to review comments
Below is the v1.6 version v4l2-compliance report for the mt8173 encoder driver.
Now there are still 2 test fail in v1.6.
For VIDIOC_REQBUFS/CREATE_BUFS/QUERYBUF, we directly use v4l2_m2m_ioctl_* functions, but it still
fail. It pass in kernel 3.18 but fail in kernel 4.4.
We will try v1.8 in next version.
VIDIOC_EXPBUF is becuase we support all three memory types VB2_DMABUF, VB2_MMAP and VB2_USERPTR.
VIDIOC_EXPBUF only allowed when only VB2_MMAP supported.

The purpose of this series is to add the driver for video codec hw embedded in the Mediatek's MT8173 SoCs.
Mediatek Video Codec is able to handle video encoding of in a range of formats.

In principle the driver bases on v4l2 memory-to-memory framework:
it provides a single video node and each opened file handle gets its own private context with separate

The VPU driver for hw video codec embedded in Mediatek's MT8173 SOCs.
It is able to handle video decoding/encoding in a range of formats.
The driver provides with VPU firmware download, memory management and the communication interface between CPU and VPU.
For VPU initialization, it will create virtual memory for CPU access and physical address for VPU hw device access.
When a decode/encode instance opens a device node, vpu driver will download vpu firmware to the device.
A decode/encode instant will decode/encode a frame using VPU interface to interrupt vpu to handle decoding/encoding jobs.
Please have a look at the code and comments will be very much appreciated.
Change in v9:
1. Rename idx in mtk_vcodec_ctx to id and curr_max_idx in mtk_vcodec_dev to id_counter.
2. Refine fops_vcodec_open
VPU part
Merge Julia Lawall's fixes[1][2] to "[PATCH v9 2/8] [media] VPU: mediatek: support Mediatek VPU"
[1][PATCH] VPU: mediatek: fix simple_open.cocci warnings
[2][PATCH] VPU: mediatek: fix platform_no_drv_owner.cocci warnings
Change in v8:
1. Refine indentation
2. Refine colorspace information process vidioc_try_fmt_vid_out_mplane
3. Remove instance_mask in mtk_vcodec_dev, use curr_max_idx for instance index
4. Use kzalloc to allocate ctx
5. Refine fops_vcodec_open
VPU Part
1. Refine vpu_load_firmware
Change in v7:
1. Rebase against the master branch of git://linuxtv.org/media_tree.git
2. Add ycbcr_enc, quantization and xfer_func in try_fmt, g_fmt, s_fmt
3. Merge h264_enc and vp8_enc to venc directory
Change in v6:
1. Add synchronization access protect between irq handler and work thread
2. Add DMA_ATTR_ALLOC_SINGLE_PAGES support
3. S_FMT will return coded_width, coded_height, so user space could allocate correct size memory that HW required
4. merge h264/vp8 enc ap and md32 ipi msg
5. separate h264/vp8 enc gop_size and intra_period handle
6. remove sizeimage relative code in work buffer function
7. Refine makefile to build as an module
8. Code clean up
VPU Part
1. export symbols for building VPU as an module
2. change function from "wait_event_interruptible_timeout" to "wait_event_timeout" since
CPU needs to wait for ACK from VPU even if it was interrupted by a signal

Change in v3:
1.Refine code to pass v4l2-compliance test, now it still has 2 issues 2.Refine code according to latest MTK
IOMMU patches[1] 3.Remove MFC51 specific CIDs and add MTK specific CIDs for for keyframe and
skip I-frame
4.Refine code according to review comments
Below is the v1.6 version v4l2-compliance report for the mt8173 encoder driver.
Now there are still 2 test fail in v1.6.
For VIDIOC_REQBUFS/CREATE_BUFS/QUERYBUF, we directly use v4l2_m2m_ioctl_* functions, but it still
fail. It pass in kernel 3.18 but fail in kernel 4.4.
We will try v1.8 in next version.
VIDIOC_EXPBUF is becuase we support all three memory types VB2_DMABUF, VB2_MMAP and VB2_USERPTR.
VIDIOC_EXPBUF only allowed when only VB2_MMAP supported.

The VPU driver for hw video codec embedded in Mediatek's MT8173 SOCs.
It is able to handle video decoding/encoding of in a range of formats.
The driver provides with VPU firmware download, memory management and
the communication interface between CPU and VPU.
For VPU initialization, it will create virtual memory for CPU access and
IOMMU address for vcodec hw device access. When a decode/encode instance
opens a device node, vpu driver will download vpu firmware to the device.
A decode/encode instant will decode/encode a frame using VPU
interface to interrupt vpu to handle decoding/encoding jobs.

From: Andrew-CT Chen <andrew-ct.chen-NuS5LvNUpcJWk0Htik3J/w@public.gmane.org>
The VPU driver for hw video codec embedded in Mediatek's MT8173 SOCs.
It is able to handle video decoding/encoding of in a range of formats.
The driver provides with VPU firmware download, memory management and
the communication interface between CPU and VPU.
For VPU initialization, it will create virtual memory for CPU access and
IOMMU address for vcodec hw device access. When a decode/encode instance
opens a device node, vpu driver will download vpu firmware to the device.
A decode/encode instant will decode/encode a frame using VPU
interface to interrupt vpu to handle decoding/encoding jobs.

@ 2016-04-26 8:58 ` Tiffany Lin
0 siblings, 0 replies; 33+ messages in thread
From: Tiffany Lin @ 2016-04-26 8:58 UTC (permalink / raw)
To: linux-arm-kernel
From: Andrew-CT Chen <andrew-ct.chen@mediatek.com>
The VPU driver for hw video codec embedded in Mediatek's MT8173 SOCs.
It is able to handle video decoding/encoding of in a range of formats.
The driver provides with VPU firmware download, memory management and
the communication interface between CPU and VPU.
For VPU initialization, it will create virtual memory for CPU access and
IOMMU address for vcodec hw device access. When a decode/encode instance
opens a device node, vpu driver will download vpu firmware to the device.
A decode/encode instant will decode/encode a frame using VPU
interface to interrupt vpu to handle decoding/encoding jobs.

I build this using my daily build setup and got a bunch of errors and warnings
from both the compiler (when this driver is compile-tested on a 32 bit arch)
and from sparse/smatch.
Can you fix these?

I build this using my daily build setup and got a bunch of errors and warnings
from both the compiler (when this driver is compile-tested on a 32 bit arch)
and from sparse/smatch.
Can you fix these?
