No, SRAM cannot be used on OMAP3s, as SRAM is too small to hold a framebuffer. And no, I don't think it's reserving it from RAM not managed by the kernel. What is actually failing there? Looking at Ameya's original post, the problem is in allocating the framebuffer. Your patch is doing something _after_ the allocation has failed, so I don't see Ameya's problem having anything to do with ioremap. Ameya, you could try turning on the debugs in drivers/video/omap2/vram.c, and checking what it says. Or see what is in debugfs/vram file Tomi -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
