Re: [Xen-devel] [PATCH] qemu sdl blitting

Hi all,
right now qemu takes care of converting pixels between the guest pixel format and the sdl pixel format, after that qemu also memcpy the converted pixels to the sdl buffer in video ram. This process can be improved using the SDL blit capabilities: the patch I am attaching creates an SDL Surface from the Cirrus VGA framebuffer and uses SDL blitting functions to convert and write pixels to video ram. SDL blitting functions are optimized and can even be hardware accelerated on some platforms.
