Subject: [PATCH] crypto: octeontx2 - Fix objects shared between several modules
Date: Mon, 6 Feb 2023 13:18:50 +0800	[thread overview]
Message-ID: <Y+CNuieL3rqgrfip@gondor.apana.org.au> (raw)
In-Reply-To: <20221119225650.1044591-14-alobakin@pm.me>

From: Alexander Lobakin <alobakin@pm.me>

cn10k_cpt.o, otx2_cptlf.o and otx2_cpt_mbox_common.o are linked
into both rvu_cptpf and rvu_cptvf modules:

> scripts/Makefile.build:252: ./drivers/crypto/marvell/octeontx2/Makefile:
> cn10k_cpt.o is added to multiple modules: rvu_cptpf rvu_cptvf
> scripts/Makefile.build:252: ./drivers/crypto/marvell/octeontx2/Makefile:
> otx2_cptlf.o is added to multiple modules: rvu_cptpf rvu_cptvf
> scripts/Makefile.build:252: ./drivers/crypto/marvell/octeontx2/Makefile:
> otx2_cpt_mbox_common.o is added to multiple modules: rvu_cptpf rvu_cptvf

Despite they're build under the same Kconfig option
(CONFIG_CRYPTO_DEV_OCTEONTX2_CPT), it's better do link the common
code into a standalone module and export the shared functions. Under
certain circumstances, this can lead to the same situation as fixed
by commit 637a642f5ca5 ("zstd: Fixing mixed module-builtin objects").
Plus, those three common object files are relatively big to duplicate
them several times.

Introduce the new module, rvu_cptcommon, to provide the common
functions to both modules.

Fixes: 19d8e8c7be15 ("crypto: octeontx2 - add virtual function driver support")
