It uses already present thermal infrastructure to provide boost hysteresis. The TMU data has been modified to work properly with or without boost. Signed-off-by: Lukasz Majewski Signed-off-by: Myungjoo Ham --- Changes for v11: - Use only one thermal data set - Adjust Exynos4412 thermal data to work with or without BOOST Changes for v10: - Remove boost related code from thermal_core.c - Use already present thermal infrastructure to provide thermal hysteresis - Introduce special set of TMU data for BOOST Changes for v9: - None Changes for v8: - Move cpufreq_boost_* stub functions definition (needed when cpufreq is not compiled in) to cpufreq.h at cpufreq core support commit Changes for v7: - None Changes for v6: - Disable boost only when supported and enabled - Protect boost related thermal_zone_device struct fields with mutex - Evaluate temperature trend during boost enable decision - Create separate methods to handle boost enable/disable (thermal_boost_{enable|disable}) operations - Boost is disabled at any trip point passage (not only the non critical one) - Add stub definitions for cpufreq boost functions used when CONFIG_CPU_FREQ is NOT defined. Changes for v5: - Move boost disable code from cpu_cooling.c to thermal_core.c (to handle_non_critical_trips) - Extent struct thermal_zone_device by adding overheated bool flag - Implement auto enable of boost after device cools down - Introduce boost_polling flag, which indicates if thermal uses it's predefined pool delay or has woken up thermal workqueue only to wait until device cools down. Changes for v4: - New patch drivers/thermal/samsung/exynos_tmu_data.c | 12 ++++++------ 1 file changed, 6 insertions(+), 6 deletions(-) diff --git a/drivers/thermal/samsung/exynos_tmu_data.c b/drivers/thermal/samsung/exynos_tmu_data.c index 073c292..476b768 100644 --- a/drivers/thermal/samsung/exynos_tmu_data.c +++ b/drivers/thermal/samsung/exynos_tmu_data.c @@ -131,8 +131,8 @@ static const struct exynos_tmu_registers exynos4412_tmu_registers = { #define EXYNOS4412_TMU_DATA \ .threshold_falling = 10, \ - .trigger_levels[0] = 85, \ - .trigger_levels[1] = 103, \ + .trigger_levels[0] = 70, \ + .trigger_levels[1] = 95, \ .trigger_levels[2] = 110, \ .trigger_levels[3] = 120, \ .trigger_enable[0] = true, \ @@ -155,12 +155,12 @@ static const struct exynos_tmu_registers exynos4412_tmu_registers = { .second_point_trim = 85, \ .default_temp_offset = 50, \ .freq_tab[0] = { \ - .freq_clip_max = 800 * 1000, \ - .temp_level = 85, \ + .freq_clip_max = 1400 * 1000, \ + .temp_level = 70, \ }, \ .freq_tab[1] = { \ - .freq_clip_max = 200 * 1000, \ - .temp_level = 103, \ + .freq_clip_max = 400 * 1000, \ + .temp_level = 95, \ }, \ .freq_tab_count = 2, \ .registers = &exynos4412_tmu_registers, \ -- 1.7.10.4
