From: Geert Uytterhoeven Date: Tue, 16 Oct 2007 08:29:51 +0000 (-0700) Subject: ps3fb: enhance horizontal panning on firmware 1.90 and up X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=61e0b28e5435ac3010746bcf24fe8a16425d0343;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git ps3fb: enhance horizontal panning on firmware 1.90 and up ps3fb: Enhance horizontal panning on firmware 1.90 and up: - On firmware 1.90 and up, L1GPU_CONTEXT_ATTRIBUTE_FB_BLIT supports copying rectangles from XDR to DDR memory with different source and destination line lengths. Hence larger horizontal virtual resolutions can be supported (up to 16368 pixels). - As the actual frame buffer memory layout no longer matches the entries in ps3fb_res[], create fake struct ps3fb_ioctl_res data for the PS3FB_IOCTL_SCREENINFO ioctl, so user space applications that depend on it keep on working.
