Test code of embedded DMA design based on dwc controller.
Show the controller registered with dmatest, and you can assigned the
correspond test_dev for test:
echo show > ./sys/module/pcie_dw_dmatest/parameters/dmatest
Check the value of the current parameter:
grep -H . /sys/module/pcie_dw_dmatest/parameters/*

Before this commit the following scenario maybe disable win failed:
-> disable win and config done
-> vop fs coming, this time win state is disabled.
-> enable win and config done
-> disable win[the fs haven't come yes, so win state is disabled, this will
skip to disable win and lead to disable win failed]
->fs coming, this time win state is still enabled.
so we add judge win backup register state to avoid disable win failed.

CMA alloc may failure due to page busy caused by isolated failure,
it's helpful to dump page owner stack for debug.
To use this debug, there should enable PAGE_OWNER debug first by
- CONFIG_PAGE_OWNER=y
- add “page_owner=on” to boot cmdline
then it will shows as following:

The mst of yrgb/uv must start at a byte aligned address with a full
group of pixel.
For a pixel with NV15 format, the y channel has 10 bits and uv channel
has 5 bits. So limit the alignment to 8 pixel(10 bytes for Y, and 5 bytes
for UV) to meet this requirement.
For a pixel with NV12 format, we should limit the alignment to 2 pixel.

Show the CMA pages used by cma_alloc in meminfo node.
Tested on RV1126 EVB DDR3:
CmaTotal: 270336 kB
CmaAllocated: 44408 kB
CmaReleased: 225928 kB
CmaFree: 0 kB
The CmaTotal = CmaAllocated + CmaReleased, and the CmaFree is pages
under cma area unused by system.
The CmaAllocated can be calculated by CMA_DEBUGFS.
Tested on RV1126 EVB DDR3:
cat /sys/kernel/debug/cma/*/used
10756
346
The results from cma used is in page count, 1 page = 4kByte
CmaAllocated = 44408kB = 10756 + 346 pages
