Update vmeta to use the dma_buf handling now provided by libbmm v2.
This permits more flexible buffer management, as the buffers can now
be passed via a standardized mechanism to other subsystems (such as
DRM), and image data to be encoded can be accepted directly from
other subsystems without needing to be copied.

This removes all support for the uio-based interface from libvmeta,
replacing it with the new miscdevice interface code. This represents
a substantial cleanup of this code.
|
|
The kernel folk don't like the uio ioctl idea, so we can't use uio for
this driver. Instead, switch it to be a self-contained miscdevice.
This adds support to this library for the miscdevice interface.

Provide a common function to read the size and physical address from a
UIO map, and to mmap() the UIO map if desired. This avoids a lot of
repeated code in several functions.
|
|
This avoids a whole raft of completely unnecessary casts.

Unmap useless virtual memory in user space.
Code clean: replace all printf() with dbg_printf().
Add gst fix.

Under Android, we cannot use printf. So we write to a debug file instead.
It's useful under Android.
