[dpdk-dev] [PATCH] net/octeontx: meson build fix if octeontx drivers are disabled

[agupta3]

From: Amit Gupta <agupta3@marvell.com>

Add a condition to check if octeontx drivers are disabled.
octeontx drivers are built only if dependent drivers i.e.
ethdev, mempool and common/octeontx are enabled.

Interesting format, but we prefer consistency, you can see this in git history.
Bugzilla ID: xxx

This can be caught by running the devtools/check-git-log.sh script.

I am no meson expert, but I'd say you can put a subdir_done() if your
check is false and then you don't need to check the build variable
later.
Besides, you can most likely do this check at the top of this file
alongside "depends".

Unrelated change + whitespace damage after.

A better fix here might be possible using the fact that the get_variable()
call allows passing a fallback value in the case of failure. Therefore
something like the below might work cleaner:

foreach d: depends
	static_obj = [get_variable('static_rte_' + d, '']
	if static_obj == ''
		build = false
		reason = '....'
		subdir_done()
	endif
	static_objs += static_obj
...

Maybe a disabler object could be used also.

[dpdk-dev] [PATCH v2 1/1] net/octeontx: fix meson build for disabled octeontx drivers

Add a additional condition to check if all required internal 
dependencies are met before building octeontx drivers using meson.

very minor nit - you can use "test_dep_obj" here rather than calling
get_variable twice.

[Amit Gupta]

test_dep_obj is being formatted as string object, so can't be used as static obj..

Apologies, you are quite right, I missed that.

One final suggestion - the "is_variable" function is probably want you want

[dpdk-dev] [PATCH v3 1/1] net/octeontx: fix meson build for disabled octeontx drivers

[agupta3]

From: Amit Gupta <agupta3@marvell.com>

Add a condition to check if octeontx drivers are disabled.
octeontx drivers are built only if dependent drivers i.e.
ethdev, mempool and common/octeontx are enabled.

Bugzilla ID: 387

Fixes: 7f615033d64f ("drivers/net: build Cavium NIC PMDs with meson")
