[dpdk-dev] [PATCH] eal: move compat includes to common meson file

[dpdk-dev] [PATCH] eal: move compat includes to common meson file

[Anatoly Burakov]

Currently, while EAL does depend on librte_compat as far as common
meson build is concerned, for some reason the headers for that
library are not added into the list of includes. This is fixed in
Linuxapp-specific meson file, but is absent from FreeBSD meson file.

This worked fine up until recently, when an rte_compat dependency
was added to rte_log, which is a common header. Fix this issue by
adding librte_compat includes to common EAL meson file.

Agreed.
One other point I'd make is that having compat as a separate library seems
a little like overkill to me - it's just one header file! Is there a reason
why we don't just move it into the EAL where everyone can use it without
having to specify another dependency?

+1 for moving compat into EAL.

Presumably the reason to keep it separate would be to enable depending 
on it for libraries that EAL itself depends on (i.e. kvargs).

I also forgot that. However, that does bring up the thought that for some
of our headers we may want them available for all libraries even before EAL
is compiled up. [I think this hits on the idea Thomas was discussing of
splitting EAL up into two, where we have a core part that is always
compiled first and has no dependencies followed by another which is built
later and can have dependencies.]

For this specific issue, my thought is that we should indeed move compat.h
into EAL, but also add the EAL common/include/ path to the global include
path for the project, so all EAL headers (e.g. including those with defines
for cacheline size, and other common macros) are just always available.
Libs like kvargs and others should be able to use RTE_DIM etc. for
consistency with the rest of DPDK.

You are describing a cheap split :)
It would bring some definitions but not some non-inline functions.

I still think we should split in 2 libraries:
	- EAL as "Environment Abstraction Layer", i.e. basic stuffs
	- Initialization + core features (bus/dev and mem)
We could even move bus/dev and mem in separate libraries.

I don't think it is that quick to do, so, for the time being, do we go with

While I'm not splitting EAL up, I have got a working patch for merging
compat into EAL, and it seems to build ok for meson and ninja. I'll send it

it doesn't appear that compat is used by kvargs, despite it being listed as
a dependency of it.
