[dpdk-dev] [PATCH 00/10] enhance meson summary - list disabled components

[dpdk-dev] [PATCH 00/10] enhance meson summary - list disabled components

[Bruce Richardson]

After using meson to configure a build, we output a brief list of all
components that are enabled. However, of more use to most users is a
list of what is not being enabled, so that they can look for gaps and
see about fixing those gaps, e.g. by installing driver dependencies.

This patchset adds such a printout at the end, but to make things
easier, it also adds support for drivers adding a reason why they not
being built, e.g. unsupported platform, or missing software dependency.

Example output from a FreeBSD platform, for which many drivers do not
compile:

[dpdk-dev] [PATCH 01/10] build: print list of disabled components for meson build

[Bruce Richardson]

When configuring with meson we print out a list of enabled components, but
it is also useful to list out the disabled components and the reasons why.

[dpdk-dev] [PATCH 07/10] drivers/event: add reasons for components being disabled

[Bruce Richardson]

For each driver where we optionally disable it, add in the reason why it's
being disabled, so the user knows how to fix it.

[dpdk-dev] [PATCH 10/10] drivers/raw: add reasons for components being disabled

[Bruce Richardson]

For each driver where we optionally disable it, add in the reason why it's
being disabled, so the user knows how to fix it.
