内核编译图文教程，显卡篇
首先是我的显卡是什么显卡。
cheng@chpc:~$ lspci | grep VGA
00:01.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Wrestler [Radeon HD 6310]
cheng@chpc:~$
我的显卡是Radeon HD 6310，pci显卡，集成显卡。
CONFIG_AGP_AMD64该项仅适用于如下AMD处理器:(1)AMD K8微架构CPU[cpu family : 15]
(2)AMD K10微架构CPU[cpu family : 16]
(3)AMD 推土机微架构CPUk即是k15架构[cpu family : 21 并且 model: 小于15
我的是k14芯片组cpu family 是20
可以用cat /proc/cpuinfo得到cpu family
可以用lspci看看芯片组的情况，下面显示是amd k14芯片组
cheng@chpc:~$ lspci | grep -i host\ bridge
00:00.0 Host bridge: Advanced Micro Devices, Inc. [AMD] Family 14h Processor Root Complex
config_vesa 应该选上不然会出错
