Hi Eduardo, Zhang, > This patch provides auto disable/enable operation for boost. It uses > already present thermal infrastructure to provide boost hysteresis. > A special set of TMU data has been defined for Exynos4412, which is > only considered when BOOST is enabled. > > Signed-off-by: Lukasz Majewski <l.majewski@xxxxxxxxxxx> > Signed-off-by: Myungjoo Ham <myungjoo.ham@xxxxxxxxxxx> > > --- > 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 Eduardo, Zhang any comments on this patch? > > 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 | 47 > +++++++++++++++++++++++++++++ 1 file changed, 47 insertions(+) > > diff --git a/drivers/thermal/samsung/exynos_tmu_data.c > b/drivers/thermal/samsung/exynos_tmu_data.c index 073c292..9346926 > 100644 --- a/drivers/thermal/samsung/exynos_tmu_data.c > +++ b/drivers/thermal/samsung/exynos_tmu_data.c > @@ -167,13 +167,60 @@ static const struct exynos_tmu_registers > exynos4412_tmu_registers = { .features = (TMU_SUPPORT_EMULATION | > TMU_SUPPORT_TRIM_RELOAD | \ TMU_SUPPORT_FALLING_TRIP | > TMU_SUPPORT_READY_STATUS | \ TMU_SUPPORT_EMUL_TIME) > + > +#define EXYNOS4412_TMU_DATA_BOOST \ > + .threshold_falling = 10, \ > + .trigger_levels[0] = 70, \ > + .trigger_levels[1] = 85, \ > + .trigger_levels[2] = 103, \ > + .trigger_levels[3] = 110, \ > + .trigger_enable[0] = true, \ > + .trigger_enable[1] = true, \ > + .trigger_enable[2] = true, \ > + .trigger_enable[3] = true, \ > + .trigger_type[0] = THROTTLE_ACTIVE, \ > + .trigger_type[1] = THROTTLE_ACTIVE, \ > + .trigger_type[2] = THROTTLE_ACTIVE, \ > + .trigger_type[3] = SW_TRIP, \ > + .max_trigger_level = 4, \ > + .gain = 8, \ > + .reference_voltage = 16, \ > + .noise_cancel_mode = 4, \ > + .cal_type = TYPE_ONE_POINT_TRIMMING, \ > + .efuse_value = 55, \ > + .min_efuse_value = 40, \ > + .max_efuse_value = 100, \ > + .first_point_trim = 25, \ > + .second_point_trim = 85, \ > + .default_temp_offset = 50, \ > + .freq_tab[0] = { \ > + .freq_clip_max = 1400 * 1000, \ > + .temp_level = 70, \ > + }, \ > + .freq_tab[1] = { \ > + .freq_clip_max = 800 * 1000, \ > + .temp_level = 85, \ > + }, \ > + .freq_tab[2] = { \ > + .freq_clip_max = 200 * 1000, \ > + .temp_level = 103, \ > + }, \ > + .freq_tab_count = 3, \ > + .registers = &exynos4412_tmu_registers, \ > + .features = (TMU_SUPPORT_EMULATION | TMU_SUPPORT_TRIM_RELOAD > | \ > + TMU_SUPPORT_FALLING_TRIP | > TMU_SUPPORT_READY_STATUS | \ > + TMU_SUPPORT_EMUL_TIME) > #endif > > #if defined(CONFIG_SOC_EXYNOS4412) > struct exynos_tmu_init_data const exynos4412_default_tmu_data = { > .tmu_data = { > { > +#ifdef CONFIG_CPU_FREQ_BOOST_SW > + EXYNOS4412_TMU_DATA_BOOST, > +#else > EXYNOS4412_TMU_DATA, > +#endif > .type = SOC_ARCH_EXYNOS4412, > .test_mux = EXYNOS4412_MUX_ADDR_VALUE, > }, -- Best regards, Lukasz Majewski Samsung R&D Institute Poland (SRPOL) | Linux Platform Group -- To unsubscribe from this list: send the line "unsubscribe cpufreq" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
