Subject: [igt-dev] [PATCH i-g-t v3 07/21] lib/igt_fb: Add a helper to retreive the plane bpp for a given format
Date: Fri, 11 Jan 2019 10:05:18 +0100	[thread overview]
Message-ID: <20190111090532.19235-8-paul.kocialkowski@bootlin.com> (raw)
In-Reply-To: <20190111090532.19235-1-paul.kocialkowski@bootlin.com>

The format bpp for a given plane is stored in the static format_desc
structure and is not accessible to tests, which is inconvenient to
get the minimum stride for a format when testing various strides.

Add a simple helper to expose the information.
