It has been tested on Trats2 board (using Exynos4412 SoC with secure firmware enabled) on which AFTR mode reduces power consumption by ~12% when EXYNOS cpuidle driver is enabled (in both cases the default exynos_defconfig config is used and CPU1-3 are offlined). Depends on: - next-20140804 branch of linux-next kernel tree - [PATCH v4][next-20140804] ARM: EXYNOS: Fix suspend/resume sequences (http://www.mail-archive.com/linux-samsung-soc@vger.kernel.org/msg35192.html) - [PATCH v2 0/2] Firmware-assisted suspend/resume of Exynos SoCs (http://www.mail-archive.com/linux-samsung-soc@vger.kernel.org/msg34282.html) Changes since v3: - rebased on top of next-20140804 + [PATCH v4][next-20140804] ARM: EXYNOS: Fix suspend/resume sequences (http://www.mail-archive.com/linux-samsung-soc@vger.kernel.org/msg35192.html) [PATCH v2 0/2] Firmware-assisted suspend/resume of Exynos SoCs (http://www.mail-archive.com/linux-samsung-soc@vger.kernel.org/msg34282.html) - (re-)added patch fixing S5P_CENTRAL_SEQ_OPTION register setup Changes since v2: - rebased on top of next-20140708 + [PATCH 5/6] ARM: EXYNOS: Fix suspend/resume sequencies (http://www.mail-archive.com/linux-samsung-soc@vger.kernel.org/msg32809.html) [with rejects fixed] [PATCH 6/6] ARM: EXYNOS: Register cpuidle device only on Exynos4210 and 5250 (http://www.mail-archive.com/linux-samsung-soc@vger.kernel.org/msg32808.html) [PATCH 0/2] Firmware-assisted suspend/resume of Exynos SoCs (http://www.mail-archive.com/linux-samsung-soc@vger.kernel.org/msg32991.html) [with rejects fixed in patch #2] - addressed review comments from Tomasz Figa and Daniel Lezcano Changes since v1: - synced against next-20140602 - added missing Acked-by-s Best regards, -- Bartlomiej Zolnierkiewicz Samsung R&D Institute Poland Samsung Electronics Bartlomiej Zolnierkiewicz (5): ARM: EXYNOS: PM: replace EXYNOS_BOOT_VECTOR_* macros by static inlines ARM: EXYNOS: add AFTR mode support to firmware do_idle method ARM: EXYNOS: cpuidle: add secure firmware support to AFTR mode code ARM: EXYNOS: PM: fix register setup for AFTR mode code ARM: EXYNOS: cpuidle: allow driver usage on Exynos4x12 SoCs arch/arm/include/asm/firmware.h | 2 +- arch/arm/mach-exynos/common.h | 5 ++++ arch/arm/mach-exynos/exynos.c | 4 ++- arch/arm/mach-exynos/firmware.c | 33 ++++++++++++++++------- arch/arm/mach-exynos/pm.c | 60 ++++++++++++++++++++++++----------------- 5 files changed, 69 insertions(+), 35 deletions(-) -- 1.8.2.3 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
