CPU frequency and voltage scaling code in the linux(TM) kernel L i n u x C P U F r e q Dominik Brodowski [email=linux@brodo.de]linux@brodo.de[/email] Clock scaling allows you to change the clock speed of the CPUs on the fly. This is a nice method to save battery power, because the lower the clock speed, the less power the CPU consumes. Documents in this direc...

本帖最后由 Hugo801122 于 2014-03-10 10:05 编辑 本文详细介绍了lcd的控制时序和原理，linux系统下的lcd驱动架构， 并结合S3C2410分析了一个实例，20页，值得参考。 附件： 也可以从网盘地址下载： http://url.cn/QdgrPe
各位好: 显卡 : intel 集成显卡 (GM45) 驱动 : IEGD 或 系统自带 i915 驱动 请问下, 如何 写程序 调整 LVDS 设备 的 对比度 亮度, 饱和度 等 ??? 谢谢
这一个多星期主要在搞linux lcd驱动，期间对内核源码中的drivers/video/s3c2410fb.c文件产生了一些疑惑如下： 首先请看如下的两张图片 接下来就是我的疑问了：modify_gpio(S3C2410_GPCUP, mach_info->gpcup, mach_info->gpcup_mask);中的S3C2410_GPCUP是物理地址啊？怎么能够直接访问呢？不是应该先向操作系统申请，然后再进行虚实地址映射后才可以使用吗？ 不知道我的分析错在哪里了，希望大家...
