This patch supports the DFL drivers be written in userspace. This is

In v2, we use a new matching algorithem.

Allow user to set metric on default route learned via Router Advertisement.
Note: RFC 4191 does not say anything for metric for IPv6 default route.
Fix:
For IPv4, default route is learned via DHCPv4 and user is allowed to change

For IPv4, default route is learned via DHCPv4 and user is allowed to change
metric using config etc/network/interfaces. But for IPv6, default route can
be learned via RA, for which, currently a fixed metric value 1024 is used.
Ideally, user should be able to configure metric on default route for

As per DP-1.3, First check DP_EXTENDED_RECEIVER_CAP_FIELD_PRESENT.
If DP_EXTENDED_RECEIVER_CAP_FIELD_PRESENT is 1,read the DP_DP13_DPCD_REV to
get the faster capability.
If DP_EXTENDED_RECEIVER_CAP_FIELD_PRESENT is 0,read DP_DPCD_REV.

This patch supports chunk heap that allocates the buffers that
arranged into a list a fixed size chunks taken from CMA.
The chunk heap driver is bound directly to a reserved_memory
node by following Rob Herring's suggestion in [1].
[1]
Contiguous memory allocation can be stalled due to waiting
on page writeback and/or page lock which causes unpredictable
delay. It's a unavoidable cost for the requestor to get *big*
contiguous memory but it's expensive for *small* contiguous
memory(e.g., order-4) because caller could retry the
This patchset introduces a new dma heap, "chunk-heap" that makes it
easy to perform the bulk allocation of high order pages.
It has been created to help optimize the 4K/8K HDR video playback
with secure DRM HW to protect contents on memory. The HW needs
physically contiguous memory chunks(e.g,
The upcoming patch will introduce __GFP_NORETRY semantic
in alloc_contig_range which is a failfast mode of the API.
Instead of adding a additional parameter for gfp, replace
no_warn with gfp flag.
To keep old behaviors, it follows the rule below.

Modules with a large number of compilation units may be
exceeding AR and LD command argument list. Handle this gracefully by
writing the long argument list in a file. The command line options
read from file are inserted in place of the original @file option.
Fedora Rawhide has started including gcc 11,and the g++ compiler
throws a wobbly when it hits scripts/gcc-plugins:

Modules with a large number of compilation units can exceed execv
argument list resulting in E2BIG (Argument list too long) error.
Fix this by replacing shell 'echo > file' into a more native
$(file op filename[,text]) option.
