Hi,all I'm using FC5, our graphic card's framebuffer driver's ioctl function work abnormally.I mean our framebuffer driver provide extending ioctl command. But the ioctl cmd can't be transport correctly from user space to kernel space, ie,if I ioctl(fd,0x123456,&arg) in user space, the kernel space can not get the cmd 0x12345, but a totally different number. But if I use standard cmd such as FBIOGET_VSCREENINFO, it work normally. By the way, My framebuffer driver work on FC4 Any Suggestion is appreciate. |
