Subject: [PATCH] parisc: fbdev/stifb: Align graphics memory size to 4MB
Date: Fri, 14 Oct 2022 20:53:26 +0200 [thread overview]
Message-ID: <Y0mwJrtT+XyXAjQS@p100> (raw)
Independend of the current graphics resolution, adjust the reported
graphics card memory size to the next 4MB boundary.
This fixes the fbtest program which expects a naturally aligned size.
