So I tried to launch it with latest kernel and success with simple trick. however it's same, hanging. Why it goes hang even though it doesn't use PM mode. :) Anyway you can achieve it with followings. First, copy required files from android kernel to latest one. drivers/android/* drivers/misc/lowmemorykilller/* include/linux/android* include/linux/binder* include/linux/logger.h Second, it can't compile android_power since the APIs are changed. So you register fake alarm to logger [2]. Finally launches it. I hope it's helpful you. Thank you, Kyungmin Park 1. android.patch diff --git a/arch/arm/Kconfig b/arch/arm/Kconfig index eeda0cd..b277768 100644 --- a/arch/arm/Kconfig +++ b/arch/arm/Kconfig @@ -1173,6 +1173,8 @@ source "drivers/dma/Kconfig" source "drivers/dca/Kconfig" +source "drivers/android/Kconfig" + if ARCH_OMAP source "drivers/cbus/Kconfig" source "drivers/dsp/dspgateway/Kconfig" diff --git a/drivers/Makefile b/drivers/Makefile index ea7baa4..a3425be 100644 --- a/drivers/Makefile +++ b/drivers/Makefile @@ -98,3 +98,4 @@ obj-$(CONFIG_PPC_PS3) += ps3/ obj-$(CONFIG_OF) += of/ obj-$(CONFIG_SSB) += ssb/ obj-$(CONFIG_VIRTIO) += virtio/ +obj-y += android/ diff --git a/drivers/misc/Kconfig b/drivers/misc/Kconfig index 982e27b..06ade5a 100644 --- a/drivers/misc/Kconfig +++ b/drivers/misc/Kconfig @@ -326,4 +326,10 @@ config ENCLOSURE_SERVICES driver (SCSI/ATA) which supports enclosures or a SCSI enclosure device (SES) to use these services. +config LOW_MEMORY_KILLER + tristate "Low Memory Killer" + ---help--- + Register processes to be killed when memory is low. + + endif # MISC_DEVICES diff --git a/drivers/misc/Makefile b/drivers/misc/Makefile index 3b12f5d..d10a556 100644 --- a/drivers/misc/Makefile +++ b/drivers/misc/Makefile @@ -22,3 +22,5 @@ obj-$(CONFIG_FUJITSU_LAPTOP) += fujitsu-laptop.o obj-$(CONFIG_EEPROM_93CX6) += eeprom_93cx6.o obj-$(CONFIG_INTEL_MENLOW) += intel_menlow.o obj-$(CONFIG_ENCLOSURE_SERVICES) += enclosure.o +obj-$(CONFIG_LOW_MEMORY_KILLER) += lowmemorykiller/ + diff --git a/drivers/video/omap/omapfb_main.c b/drivers/video/omap/omapfb_main.c index f66b81a..c206098 100644 --- a/drivers/video/omap/omapfb_main.c +++ b/drivers/video/omap/omapfb_main.c @@ -169,7 +169,7 @@ static int ctrl_init(struct omapfb_device *fbdev) /* 12 bpp is packed in 16 bits */ if (bpp == 12) bpp = 16; - def_size = def_vxres * def_vyres * bpp / 8; + def_size = def_vxres * def_vyres * 2 * bpp / 8; fbdev->mem_desc.region_cnt = 1; fbdev->mem_desc.region[0].size = PAGE_ALIGN(def_size); } @@ -423,6 +423,7 @@ static void set_fb_fix(struct fb_info *fbi) } fix->accel = FB_ACCEL_OMAP1610; fix->line_length = var->xres_virtual * bpp / 8; + fix->ypanstep = 1; } static int set_color_mode(struct omapfb_plane_struct *plane, @@ -1493,7 +1494,7 @@ static int fbinfo_init(struct omapfb_device *fbdev, struct fb_info *info) var->xres = def_vxres; var->yres = def_vyres; var->xres_virtual = def_vxres; - var->yres_virtual = def_vyres; + var->yres_virtual = def_vyres * 2; var->rotate = def_rotate; var->bits_per_pixel = fbdev->panel->bpp; 2. fack-alarm.patch --- kernel/drivers/android/logger.c 2008-02-12 11:46:56.000000000 +0900 +++ linux-omap-2.6/drivers/android/logger.c 2008-03-05 16:37:40.000000000 +0900 @@ -25,6 +25,10 @@ #include <asm/ioctls.h> +#ifndef CONFIG_ANDROID_POWER +#include <linux/android_alarm.h> +#endif + /* * struct logger_log - represents a specific log, such as 'main' or 'radio' * @@ -512,6 +516,12 @@ static long logger_ioctl(struct file *fi break; } + switch (ANDROID_ALARM_BASE_CMD(cmd)) { + printk("%s[%d] dummy alarm ioctl 0x%x\n", __func__, __LINE__, ANDROID_ALARM_BASE_CMD(cmd)); + default: + ret = 0; + } + mutex_unlock(&log->mutex); return ret; @@ -554,6 +564,9 @@ static struct logger_log VAR = { \ DEFINE_LOGGER_DEVICE(log_main, LOGGER_LOG_MAIN, 64*1024) DEFINE_LOGGER_DEVICE(log_events, LOGGER_LOG_EVENTS, 64*1024) DEFINE_LOGGER_DEVICE(log_radio, LOGGER_LOG_RADIO, 64*1024) +#ifndef CONFIG_ANDROID_POWER +DEFINE_LOGGER_DEVICE(alarm, LOGGER_LOG_ALARM, 64*1024) +#endif static struct logger_log * get_log_from_minor(int minor) { @@ -599,6 +612,12 @@ static int __init logger_init(void) if (unlikely(ret)) goto out; +#ifndef CONFIG_ANDROID_POWER + ret = init_log(&alarm); + if (unlikely(ret)) + goto out; +#endif + out: return ret; } -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
