/src/master.c:62: error: section attribute not allowed for specific_pci_
probe
/src/master.c:62: warning: __cold__ attribute ignored
下面是出错的代码, __devinit 是 include/kernel/init.h里定义的
/* Static function prototypes */
static int m_pci_probe_valid (struct pci_dev *dev,
int __devinit (*specific_pci_probe)(struct pci_dev *dev)) __devinit;
去掉__devinit再编译就没问题，只是对linux不是很熟，不知这样去掉对不对？ |

Check what __devinit does. I *think* it just marks the code in init section
so it can be discarded to save memory, but maybe there is sth else.

section
是的，__devinit 只标识了section
这么说driver里去掉__devinit没问题了？
另外kernel和driver版本冲突会不会在编译后insmod时才会体现出来呢？谢谢
include/linux/init.h
/* Used for HOTPLUG */
#define __devinit __section(.devinit.text) __cold

发帖数: 4193 | 4 I think it's the "__cold" attribute that causes your problem. Maybe it's
something to do with your gcc/binutils version.
