Report more CPU capabilities in ELF flags, and report them in bootup logs and /proc/cpuinfo. For example my /proc/cpuinfo now has a line that reads: cpucaps : flush,stbar,swap,muldiv,v9,blkinit,n2,mul32,div32,v8plus,popc,vis,vis2,ASIBlkInit,fmaf,vis3,hpc Don't use FPU for copies and clears of pages on Niagara T2, T2+, and T3. The Niagara T1 version is fast enough, and doesn't have the potential overhead of FPU state save/restore. Unroll the loops a little bit and use %asi register to decrease the overall cycle count. If available use 'popc' for hweight*(), ffs(), __ffs(), and ffz(). More recent hypervisors have a new way to record the "reboot-cmd" variable that is used to setup the boot command that will be used on soft resets. It's done purely via the hypervisor which allows parallel boot, and also allows the boot string to propagate properly into the next boot even if the service processor is down or in degraded mode. I intend to consolidate the code patching a little bit in the future. We don't need all these different patch blob structures. One with a cleverly encoded instruction count will do. Then we have one central patching routine that takes "start_pointer, end_pointer". -- To unsubscribe from this list: send the line "unsubscribe sparclinux" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
