The vfp_init() code should check for its presence and set the hwcap accordingly. Ideally, we should fix the VFP handling code to cope with dynamic detection. > HAS_TLS reg is only on ARM11 starting with r1p0: > > http://infocenter.arm.com/help/topic/com.arm.doc.ddi0211k/Babeihid.html > > So that explains why it won't work on omap2420 as it's r0p2. Same here, would it work with dynamic detection? I would like to get v6+v7 support working fine together on RealView boards as well (though not much spare time) but without disabling the features that are present on v7 if they can be detected at run-time. -- Catalin -- 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
