Subject: [PATCH 0/7] drm: Extend COMPILE_TEST support to some ARM drivers
Date: Wed, 28 Jul 2021 18:37:29 +0300	[thread overview]
Message-ID: <20210728153736.15240-1-laurent.pinchart+renesas@ideasonboard.com> (raw)

Hello,

This patch series stems from subsystem-wide changes I wanted to
compile-test with an ARM64 cross-compiler. My laziness to fire a 32-bit
ARM build probably resulted in more time being spent writing these
patches, but hopefully they'll turn out to be useful for more people :-)

Patches 1/7 and 2/7 are fixes for compilation warnings on 64-bit
platforms in the omapdrm and sti-drm drivers. They are a dependency for
the Kconfig changes that follow to avoid introducing build warnings, but
could also be merged before.

Patches 3/7 to 7/7 enable compilation of the imx-dcss, omapdrm, sti-drm,
tegra-drm and tilcdc drivers on ARM64 with COMPILE_TEST. The patches are
independent from each other, so they can be picked by their respective
maintainers.

We could also extend test compilation to more architecture, but I didn't
want to remove all dependencies on ARM or ARM64 at this point for fear
or triggering build warnings that I wouldn't be able to catch locally.
If there's a consensus that fully relaxing the platform requirement is
better, I can submit a new version that does so and rely on the 0day bot
to catch issues.
