Subject: [PATCH] pm2fb: accelerated imageblit
Date: Thu, 21 Jun 2007 17:21:34 +0200 [thread overview]
Message-ID: <467A977E.5070105@wp.pl> (raw)
[-- Attachment #1: Type: text/plain, Size: 6844 bytes --]
From: Krzysztof Helt <krzysztof.h1@wp.pl>
This patch adds accelerated imageblit function.
Signed-off-by: Krzysztof Helt <krzysztof.h1@wp.pl>
---
This patch requires all previous pm2fb patches I sent to the list (and one from the current mm tree).
Tony, please do not knock down my pm3fb patches because they do not apply cleanly. They do apply correctly (I have checked it). The mistake is due to the Adrian Bunk's patch which I forgot to use.
Regards,
Krzysztof
