Stability improvements in microcode for stop4/stop5 are available in upstream hcode images. Stop4 and stop5 can be safely enabled by default. Use ~0xE0000000 to cut all but stop0,1,2 in case there are any issues with stop4/5. example: nvram -p ibm,skiboot --update-config opal-stop-state-disable-mask=0x1FFFFFFF Signed-off-by: Vaidyanathan Srinivasan <svaidy@linux.vnet.ibm.com> --- hw/slw.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
