[PATCH v2 00/22] Exynos DRM: new life of IPP (Image Post Processing) subsystem

[Marek Szyprowski]

Dear All,

This patch series introduces a new life into Exynos IPP (Image Post
Processing) subsystem by integrating it (transparently for userspace
applications) with Exynos DRM core plane management. This means that all
CRTC drivers transparently get support for standard features of IPP
subsystem like rotation, scaling and color space conversion.

Support for features not supported natively by CRTC drivers is
implemented with a help of temporary framebuffers, where image data is
processed by IPP subsystem before performing the scanout by a CRTC driver.

This is second version of this patchset. The initial version is available
here:
http://thread.gmane.org/gmane.linux.kernel.samsung-soc/49743

The main change since v1 is support for color space conversion and minor
fixes in the preparation patches (added support for native scaling in
Exynos Video Processor module).

This feature is 'experimental'. From the initial discussion I see that
there is no consensus if this feature should be integrated seamplessly
in Exynos DRM core or provided by a separate API. This will be further
discussed.

However, I would like to ask for merging patches 1-15, which are pure
bugfixes and code cleanups. The patches are based on top of current
exynos-drm-next branch.
