PXA-Camera Host Driver
======================
Constraints
-----------
a) Image size for YUV422P format
All YUV422P images are enforced to have width x height % 16 = 0.
This is due to DMA constraints, which transfers only planes of 8 byte
multiples.
Global video workflow
---------------------
a) QCI stopped
Initialy, the QCI interface is stopped.
When a buffer is queued (pxa_videobuf_ops->buf_queue), the QCI starts.
b) QCI started
More buffers can be queued while the QCI is started without halting the
capture. The new buffers are "appended" at the tail of the DMA chain, and
smoothly captured one frame after the other.
Once a buffer is filled in the QCI interface, it is marked as "DONE" and
removed from the active buffers list. It can be then requeud or dequeued by
userland application.
Once the last buffer is filled in, the QCI interface stops.
DMA usage
---------
a) DMA flow
- first buffer queued for capture
Once a first buffer is queued for capture, the QCI is started, but data
transfer is not started. On "End Of Frame" interrupt, the irq handler
starts the DMA chain.
- capture of one videobuffer
The DMA chain starts transfering data into videobuffer RAM pages.
When all pages are transfered, the DMA irq is raised on "ENDINTR" status
- finishing one videobuffer
The DMA irq handler marks the videobuffer as "done", and removes it from
the active running queue
Meanwhile, the next videobuffer (if there is one), is transfered by DMA
- finishing the last videobuffer
On the DMA irq of the last videobuffer, the QCI is stopped.
b) DMA prepared buffer will have this structure
+------------+-----+---------------+-----------------+
| desc-sg[0] | ... | desc-sg[last] | finisher/linker |
+------------+-----+---------------+-----------------+
This structure is pointed by dma->sg_cpu.
The descriptors are used as follows :
- desc-sg[i]: i-th descriptor, transfering the i-th sg
element to the video buffer scatter gather
- finisher: has ddadr=DADDR_STOP, dcmd=ENDIRQEN
- linker: has ddadr= desc-sg[0] of next video buffer, dcmd=0
For the next schema, let's assume d0=desc-sg[0] .. dN=desc-sg[N],
"f" stands for finisher and "l" for linker.
A typical running chain is :
Videobuffer 1 Videobuffer 2
+---------+----+---+ +----+----+----+---+
| d0 | .. | dN | l | | d0 | .. | dN | f |
+---------+----+-|-+ ^----+----+----+---+
| |
+----+
After the chaining is finished, the chain looks like :
Videobuffer 1 Videobuffer 2 Videobuffer 3
+---------+----+---+ +----+----+----+---+ +----+----+----+---+
| d0 | .. | dN | l | | d0 | .. | dN | l | | d0 | .. | dN | f |
+---------+----+-|-+ ^----+----+----+-|-+ ^----+----+----+---+
| | | |
+----+ +----+
new_link
c) DMA hot chaining timeslice issue
As DMA chaining is done while DMA _is_ running, the linking may be done
while the DMA jumps from one Videobuffer to another. On the schema, that
would be a problem if the following sequence is encountered :
- DMA chain is Videobuffer1 + Videobuffer2
- pxa_videobuf_queue() is called to queue Videobuffer3
- DMA controller finishes Videobuffer2, and DMA stops
=>
Videobuffer 1 Videobuffer 2
+---------+----+---+ +----+----+----+---+
| d0 | .. | dN | l | | d0 | .. | dN | f |
+---------+----+-|-+ ^----+----+----+-^-+
| | |
+----+ +-- DMA DDADR loads DDADR_STOP
- pxa_dma_add_tail_buf() is called, the Videobuffer2 "finisher" is
replaced by a "linker" to Videobuffer3 (creation of new_link)
- pxa_videobuf_queue() finishes
- the DMA irq handler is called, which terminates Videobuffer2
- Videobuffer3 capture is not scheduled on DMA chain (as it stopped !!!)
Videobuffer 1 Videobuffer 2 Videobuffer 3
+---------+----+---+ +----+----+----+---+ +----+----+----+---+
| d0 | .. | dN | l | | d0 | .. | dN | l | | d0 | .. | dN | f |
+---------+----+-|-+ ^----+----+----+-|-+ ^----+----+----+---+
| | | |
+----+ +----+
new_link
DMA DDADR still is DDADR_STOP
- pxa_camera_check_link_miss() is called
This checks if the DMA is finished and a buffer is still on the
pcdev->capture list. If that's the case, the capture will be restarted,
and Videobuffer3 is scheduled on DMA chain.
- the DMA irq handler finishes
Note: if DMA stops just after pxa_camera_check_link_miss() reads DDADR()
value, we have the guarantee that the DMA irq handler will be called back
when the DMA will finish the buffer, and pxa_camera_check_link_miss() will
be called again, to reschedule Videobuffer3.

@ -90,7 +90,7 @@ up before calling v4l2_device_register then it will be untouched. If dev is
NULL, then you *must* setup v4l2_dev->name before calling v4l2_device_register.
The first 'dev' argument is normally the struct device pointer of a pci_dev,
usb_device or platform_device. It is rare for dev to be NULL, but it happens
usb_interface or platform_device. It is rare for dev to be NULL, but it happens
with ISA devices or when one device creates multiple PCI devices, thus making
it impossible to associate v4l2_dev with a particular parent.
@ -351,17 +351,6 @@ And this to go from an i2c_client to a v4l2_subdev struct:
struct v4l2_subdev *sd = i2c_get_clientdata(client);
Finally you need to make a command function to make driver->command()
call the right subdev_ops functions:
static int subdev_command(struct i2c_client *client, unsigned cmd, void *arg)
{
return v4l2_subdev_command(i2c_get_clientdata(client), cmd, arg);
}
If driver->command is never used then you can leave this out. Eventually the
driver->command usage should be removed from v4l.
Make sure to call v4l2_device_unregister_subdev(sd) when the remove() callback
is called. This will unregister the sub-device from the bridge driver. It is
safe to call this even if the sub-device was never registered.
@ -375,14 +364,12 @@ from the remove() callback ensures that this is always done correctly.
The bridge driver also has some helper functions it can use:
struct v4l2_subdev *sd = v4l2_i2c_new_subdev(adapter, "module_foo", "chipid", 0x36);
struct v4l2_subdev *sd = v4l2_i2c_new_subdev(v4l2_dev, adapter,
"module_foo", "chipid", 0x36);
This loads the given module (can be NULL if no module needs to be loaded) and
calls i2c_new_device() with the given i2c_adapter and chip/address arguments.
If all goes well, then it registers the subdev with the v4l2_device. It gets
the v4l2_device by calling i2c_get_adapdata(adapter), so you should make sure
to call i2c_set_adapdata(adapter, v4l2_device) when you setup the i2c_adapter
in your driver.
If all goes well, then it registers the subdev with the v4l2_device.
You can also use v4l2_i2c_new_probed_subdev() which is very similar to
v4l2_i2c_new_subdev(), except that it has an array of possible I2C addresses
