From d4c972bff3129a9dd4c22a3999fd8eba1a81531a Mon Sep 17 00:00:00 2001 From: Zack Rusin zack.rusin@broadcom.com Date: Thu, 11 Apr 2024 22:55:11 -0400 Subject: [PATCH] drm/vmwgfx: Sort primary plane formats by order of preference
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.
Nice side-effect of this change is that it makes IGT's kms_atomic plane-invalid-params pass because the test picks the first format which for vmwgfx was DRM_FORMAT_XRGB1555 and uses fb's with odd sizes which make Pixman, which IGT depends on assert due to the fact that our 16bpp formats aren't 32 bit aligned like Pixman requires all formats to be.
