The # current P9 driver works for P10, although does few extra # save-restores. P9 driver can provide the required power management # features like SMT thread folding and core level power savings on a P10 # platform. # # Until the P10 stop driver is available, revert the commit which allows # for only P9 systems to utilize cpuidle and blocks all idle stop states # for P10. CPU idle states are enabled and tested on the P10 platform # with this fix. # # This reverts commit 8747bf36f312356f8a295a0c39ff092d65ce75ae. # # Fixes: 8747bf36f312 ("powerpc/powernv/idle: Replace CPU feature check with PVR check") # Signed-off-by: Pratik Rajesh Sampat # Reviewed-by: Vaidyanathan Srinivasan # Signed-off-by: Michael Ellerman # Link: https://lore.kernel.org/r/20200826082918.89306-1-psampat@linux.ibm.com # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 16d83a540ca4e7f1ebb2b3756869b77451d31414 # < make -s -j 80 ARCH=powerpc O=/kisskb/build/powerpc-fixes_ppc6xx_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- ppc6xx_defconfig # < make -s -j 80 ARCH=powerpc O=/kisskb/build/powerpc-fixes_ppc6xx_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 80 ARCH=powerpc O=/kisskb/build/powerpc-fixes_ppc6xx_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig # make -s -j 80 ARCH=powerpc O=/kisskb/build/powerpc-fixes_ppc6xx_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- In file included from /kisskb/src/kernel/rcu/update.c:591:0: /kisskb/src/kernel/rcu/tasks.h:593:13: warning: 'show_rcu_tasks_classic_gp_kthread' defined but not used [-Wunused-function] static void show_rcu_tasks_classic_gp_kthread(void) { } ^ In file included from /kisskb/src/include/linux/skbuff.h:31:0, from /kisskb/src/include/linux/if_ether.h:19, from /kisskb/src/include/uapi/linux/ethtool.h:19, from /kisskb/src/include/linux/ethtool.h:18, from /kisskb/src/include/linux/netdevice.h:37, from /kisskb/src/drivers/net/ethernet/sfc/net_driver.h:13, from /kisskb/src/drivers/net/ethernet/sfc/ef100.c:12: /kisskb/src/drivers/net/ethernet/sfc/ef100.c: In function 'ef100_pci_parse_continue_entry': /kisskb/src/include/linux/dma-mapping.h:139:25: warning: large integer implicitly truncated to unsigned type [-Woverflow] #define DMA_BIT_MASK(n) (((n) == 64) ?
