Subject: [PATCH 1/7] fbdev: remove unnecessary banshee_wait_idle from tdfxfb
Date: Fri, 10 Sep 2004 05:34:29 +0800 [thread overview]
Message-ID: <200409100534.29454.adaplas@hotpop.com> (raw)
- This patch removes the unnecessary call to banshee_wait_idle() from
tdfxfb_copyarea, imageblit and fillrect. Removal of the sync will garner
an additional ~20% in scrolling speed.
- Removes "inverse" which generates a compile warning if modular.
