Shenoy <ego@linux.vnet.ibm.com> # Date: Thu May 31 17:45:09 2018 +0530 # # cpuidle: powernv: Fix promotion from snooze if next state disabled # # The commit 78eaa10f027c ("cpuidle: powernv/pseries: Auto-promotion of # snooze to deeper idle state") introduced a timeout for the snooze idle # state so that it could be eventually be promoted to a deeper idle # state. The snooze timeout value is static and set to the target # residency of the next idle state, which would train the cpuidle # governor to pick the next idle state eventually. # # The unfortunate side-effect of this is that if the next idle state(s) # is disabled, the CPU will forever remain in snooze, despite the fact # that the system is completely idle, and other deeper idle states are # available. # # This patch fixes the issue by dynamically setting the snooze timeout # to the target residency of the next enabled state on the device. # # Before Patch: # POWER8 : Only nap disabled. # $ cpupower monitor sleep 30 # sleep took 30.01297 seconds and exited with status 0 # \|Idle_Stats # PKG \|CORE\|CPU \| snoo \| Nap \| Fast # 0\| 8\| 0\| 96.41\| 0.00\| 0.00 # 0\| 8\| 1\| 96.43\| 0.00\| 0.00 # 0\| 8\| 2\| 96.47\| 0.00\| 0.00 # 0\| 8\| 3\| 96.35\| 0.00\| 0.00 # 0\| 8\| 4\| 96.37\| 0.00\| 0.00 # 0\| 8\| 5\| 96.37\| 0.00\| 0.00 # 0\| 8\| 6\| 96.47\| 0.00\| 0.00 # 0\| 8\| 7\| 96.47\| 0.00\| 0.00 # # POWER9: Shallow states (stop0lite, stop1lite, stop2lite, stop0, stop1, # stop2) disabled: # $ cpupower monitor sleep 30 # sleep took 30.05033 seconds and exited with status 0 # \|Idle_Stats # PKG \|CORE\|CPU \| snoo \| stop \| stop \| stop \| stop \| stop \| stop \| stop \| stop # 0\| 16\| 0\| 89.79\| 0.00\| 0.00\| 0.00\| 0.00\| 0.00\| 0.00\| 0.00\| 0.00 # 0\| 16\| 1\| 90.12\| 0.00\| 0.00\| 0.00\| 0.00\| 0.00\| 0.00\| 0.00\| 0.00 # 0\| 16\| 2\| 90.21\| 0.00\| 0.00\| 0.00\| 0.00\| 0.00\| 0.00\| 0.00\| 0.00 # 0\| 16\| 3\| 90.29\| 0.00\| 0.00\| 0.00\| 0.00\| 0.00\| 0.00\| 0.00\| 0.00 # # After Patch: # POWER8 : Only nap disabled. # $ cpupower monitor sleep 30 # sleep took 30.01200 seconds and exited with status 0 # \|Idle_Stats # PKG \|CORE\|CPU \| snoo \| Nap \| Fast # 0\| 8\| 0\| 16.58\| 0.00\| 77.21 # 0\| 8\| 1\| 18.42\| 0.00\| 75.38 # 0\| 8\| 2\| 4.70\| 0.00\| 94.09 # 0\| 8\| 3\| 17.06\| 0.00\| 81.73 # 0\| 8\| 4\| 3.06\| 0.00\| 95.73 # 0\| 8\| 5\| 7.00\| 0.00\| 96.80 # 0\| 8\| 6\| 1.00\| 0.00\| 98.79 # 0\| 8\| 7\| 5.62\| 0.00\| 94.17 # # POWER9: Shallow states (stop0lite, stop1lite, stop2lite, stop0, stop1, # stop2) disabled: # # $ cpupower monitor sleep 30 # sleep took 30.02110 seconds and exited with status 0 # \|Idle_Stats # PKG \|CORE\|CPU \| snoo \| stop \| stop \| stop \| stop \| stop \| stop \| stop \| stop # 0\| 0\| 0\| 0.69\| 0.00\| 0.00\| 0.00\| 0.00\| 0.00\| 0.00\| 9.39\| 89.70 # 0\| 0\| 1\| 0.00\| 0.00\| 0.00\| 0.00\| 0.00\| 0.00\| 0.00\| 0.05\| 93.21 # 0\| 0\| 2\| 0.00\| 0.00\| 0.00\| 0.00\| 0.00\| 0.00\| 0.00\| 0.00\| 89.93 # 0\| 0\| 3\| 0.00\| 0.00\| 0.00\| 0.00\| 0.00\| 0.00\| 0.00\| 0.00\| 93.26 # # Fixes: 78eaa10f027c ("cpuidle: powernv/pseries: Auto-promotion of snooze to deeper idle state") # Cc: stable@vger.kernel.org # v4.2+ # Signed-off-by: Gautham R.
