The table of primary plane formats wasn't sorted at all, leading to applications picking our least desirable formats by defaults.
Sort the primary plane formats according to our order of preference.
This is good.
Fixes IGT's kms_atomic plane-invalid-params which assumes that the preferred format is a 32bpp format.
That sounds strange, why would IGT depend on preferred format being 32bpp?
That must be an oversight. IGT cannot dictate the format that hardware must prefer. XRGB8888 is strongly suggested to be supported in general, but why also preferred?
Thanks, pq
