From: Adrian McMenamin Date: Fri, 10 Aug 2007 20:00:48 +0000 (-0700) Subject: pvr2fb: Consolidated cleanup of pvr2fb.c X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=306c869c237a66fe85580f60558f105e3305d465;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git pvr2fb: Consolidated cleanup of pvr2fb.c - better handling of the pvr2 registers based on more up to date information. Testing shows that it seems to work pretty well at 16bpp, 24bpp and 32bpp - including proper rendering of the boot logo at all levels (previously this was a bit broken even at 16bpp) and giving white against black text. Really detailed testing (eg with X11) requires support for the maple bus - which isn't (currently - next project assuming this is okay) available, but I have no reason to think this is broken.
