From 3157e1395674a930c74e2ef4cc4ce78dffea8569 Mon Sep 17 00:00:00 2001 From: Michael Sevakis Date: Wed, 24 Dec 2008 16:58:41 +0000 Subject: Simplify powermgmt thread loops so it calls functions turn (no more power_thread_sleep). Do other target-friendly simplifications, generic battery switch handling and split sim-specific code. Whoever can, please verify charging on the Archos Recorder (due to change in the charger duty cycle code). git-svn-id: svn://svn.rockbox.org/rockbox/trunk@19579 a1c6a512-1295-4272-9138-f99709370657 --- apps/debug_menu.c | 34 +- apps/menus/main_menu.c | 21 +- apps/screens.c | 8 +- firmware/export/config-c200.h | 5 + firmware/export/config-e200.h | 5 + firmware/export/config-h100.h | 9 +- firmware/export/config-h120.h | 8 +- firmware/export/config-h300.h | 7 + firmware/export/config-iaudiom3.h | 3 + firmware/export/config-iaudiom5.h | 3 + firmware/export/config-iaudiox5.h | 3 + firmware/export/config-ipod4g.h | 7 + firmware/export/config-ipodnano.h | 6 + firmware/export/config-ipodvideo.h | 7 + firmware/export/config-ondiofm.h | 5 + firmware/export/config-ondiosp.h | 5 + firmware/export/config-recorder.h | 2 +- firmware/export/config.h | 8 +- firmware/export/power.h | 11 +- firmware/export/powermgmt.h | 195 ++-- firmware/powermgmt.c | 1200 ++++++-------------- .../target/arm/imx31/gigabeat-s/powermgmt-imx31.c | 97 +- .../target/arm/imx31/gigabeat-s/powermgmt-target.h | 21 +- firmware/target/arm/iriver/h10/power-h10.c | 4 - .../target/arm/olympus/mrobe-100/power-mr100.c | 4 - .../target/arm/philips/hdd1630/power-hdd1630.c | 4 - .../arm/s3c2440/gigabeat-fx/powermgmt-meg-fx.c | 17 +- firmware/target/arm/tatung/tpj1022/power-tpj1022.c | 4 - .../target/sh/archos/recorder/power-recorder.c | 12 +- .../target/sh/archos/recorder/powermgmt-recorder.c | 437 ++++++- .../target/sh/archos/recorder/powermgmt-target.h | 101 ++ flash/bootbox/main.c | 3 +- uisimulator/common/SOURCES | 2 + uisimulator/common/powermgmt-sim.c | 159 +++ 34 files changed, 1315 insertions(+), 1102 deletions(-) create mode 100644 firmware/target/sh/archos/recorder/powermgmt-target.h create mode 100644 uisimulator/common/powermgmt-sim.c diff --git a/apps/debug_menu.c b/apps/debug_menu.c index beee39a09b..abb6018a10 100644 --- a/apps/debug_menu.c +++ b/apps/debug_menu.c @@ -1603,10 +1603,10 @@ static bool view_battery(void) lcd_puts(0, 2, buf); #endif #if CONFIG_CHARGING -#if CONFIG_CHARGING == CHARGING_CONTROL +#if defined ARCHOS_RECORDER snprintf(buf, 30, "Chgr: %s %s", charger_inserted() ?
