Subject: [PATCH V2 0/2] OMAPDSS: DISPC: Peformance improvement of DISPC Scaling
Date: Mon, 19 Dec 2011 08:45:22 +0000 [thread overview]
Message-ID: <1324283602-6383-1-git-send-email-cmahapatra@ti.com> (raw)
Hi everyone,
the following patch set directs to improve the scaling performance of DISPC
module which consists of two pacthes.
The first patch is based on code of Lajos Molnar <lajos@ti.com> from Android
Kernel, which updates the code with new set of coefficients to improve the
scaling performance.
The second patch is based on some very valuable suggestions by
Sebastien Fagard <s-fagard@ti.com> and directs to modify the clock
requirements for scaling to support OMAP4 and avoid clock failure issues.
I have tested these patches on OMAP2, OMAP3 AND OMAP4. To test on 2430SDP
board I have created a patch to enable the display which will follow later.
All your comments and suggestions are welcome.
Regards,
Chandrabhanu
