Subject: [igt-dev] [PATCH i-g-t v2 09/12] lib/igt_fb: Add a helper to retreive the plane bpp for a given format
Date: Thu, 13 Dec 2018 16:55:30 +0100 [thread overview]
Message-ID: <20181213155533.18048-10-paul.kocialkowski@bootlin.com> (raw)
In-Reply-To: <20181213155533.18048-1-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.
