Which seems different from upstream: 1. /* Update registers with correct frequency */ 2. iowrite32(freq, base + CNTFID0); 3. asm volatile("mcr p15, 0, %0, c14, c0, 0" : : "r" (freq)); 4. 5. /* make sure arch timer is started by setting bit 0 of CNTCR */ 6. iowrite32(1, base + CNTCR); Regards, -- Julien Grall _______________________________________________ Xen-devel mailing list Xen-devel@lists.xen.org http://lists.xen.org/xen-devel
