[1/2] include: linux: Import drm.h and drm_mode.h

26401 diff mbox series

We need DRM_FORMAT_ARGB8888 when doing eglCreateImageKHR. Copy the
drm.h and its dependent drm_mode.h so that we can use the local drm.h.

Take drm.h from kernel commit 08a99369f44e ("media: uapi: Add parameters
structs to mali-c55-config.h").

I manually exported the headers from v7.0-rc2 and verified that the
diff compared to 08a99369f44e ("media: uapi: Add parameters structs to
mali-c55-config.h") matches the changes that went in between those two
revisions. So the headers are good.

However I wonder why you used the above commit that seems unrelated to
a specific feature getting into drm.h/drm_mode.h and doesn't match a
release.

> + *
> + * This struct holds frame-buffer metadata. There are two ways to use it:
> + *
> + * - User-space can fill this struct and perform a &DRM_IOCTL_MODE_ADDFB2
> + *   ioctl to register a new frame-buffer. The new frame-buffer object ID will
> + *   be set by the kernel in @fb_id.
> + * - User-space can set @fb_id and perform a &DRM_IOCTL_MODE_GETFB2 ioctl to
> + *   fetch metadata about an existing frame-buffer.
> + *
> + * In case of planar formats, this struct allows up to 4 buffer objects with
> + * offsets and pitches per plane. The pitch and offset order are dictated by
> + * the format FourCC as defined by ``drm_fourcc.h``, e.g. NV12 is described as:
> + *
> + *     YUV 4:2:0 image with a plane of 8-bit Y samples followed by an
> + *     interleaved U/V plane containing 8-bit 2x2 subsampled colour difference
> + *     samples.
> + *
> + * So it would consist of a Y plane at ``offsets[0]`` and a UV plane at
> + * ``offsets[1]``.
> + *
> + * To accommodate tiled, compressed, etc formats, a modifier can be specified.
> + * For more information see the "Format Modifiers" section. Note that even
> + * though it looks like we have a modifier per-plane, we in fact do not. The

Please sort them.

I would have modified update-kernel-headers.sh in a separate commit
and then use it to import the two new headers from a known revision
like v6.19 and then commit them.

However, sorting of the above entries apart the resul would be the
same, so

Hi Bryan,

Thank you for the patch.

I'd like to try and keep kernel headers in sync (which, I notice now
from the git history, hasn't been done well recently). Could you please
split this in two, with one patch to add drm.h and drm_mode.h to the
script, and a second patch that updates all kernel headers to v6.19 ?

Alphabetical order please.

I took the 6.19 release.

Not sure what your preference is or your rules for syncing - not -rc6 
anyway - I guess stable releases.

So I might have missed why you mentioned
08a99369f44e ("media: uapi: Add parameters structs to
mali-c55-config.h")

as the revision at which the header was extracted from :)
