[Mesa-dev] [PATCH v14 00/36] EGL_EXT_image_dma_buf_import_modifiers with i915 CCS

[Varad Gautam]

Hi all,

Thanks for the reviews on v13, here's a new iteration of the egl modifiers
series.

The notable changes since v13 was sent by Daniel include:

* All dmabuf related functions in DRIimageExtension are now added under the
same version bump.

* Since modifier queries on a DRIimage can be handled via the winsys handle
on gallium, st/DRIimage no longer has a modifiers field, and
pscreen->resource_create_with_modifiers() does not need to return the
driver-selected modifier anymore. Thanks Lucas for suggesting this option.

* I have dropped the gallium multiplane import-refactor patch from this
series. Since not all gallium drivers would want to import a resource in the
same way (eg. etnaviv would rather sample a YUYV image as a single
pipe_resouce, while some other driver might consume it as multiple
overlapping resources with RG88/RGBA8888 samplers), it is incorrect to
assume that we can get away with this without taking the driver's vote into
account, and we can move this out of the modifiers series.

* Stricter error checks all over, style fixes etc.
