[PATCH v2 0/9] drm: Extend COMPILE_TEST support to some ARM drivers

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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 definitely resulted in more time being spent writing these
patches, but hopefully they'll turn out to be useful for more people.

Patches 1/9 to 3/7 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 3/9 to 8/9 enable compilation of the imx-dcss, omapdrm, sti-drm
and tegra-drm drivers on all architectures with COMPILE_TEST. I have
tested compilation on arm64 and x86, with W=1. The patches are
independent from each other, so they can be picked by their respective
maintainers.

The last patch, 9/9, extends COMPILE_TEST support for the tilcdc driver
to ARM64. The driver doesn't compile on x86 due to a missing __iowmb(),
and I haven't taken the time to investigate how to solve this properly.

The main change since v1 is the extension of COMPILE_TEST to all
platforms instead of only ARM and ARM64.

Please feel free to pick patches individually for the driver(s) you
maintain.
