A few days ago in contact with RTLinux, tossing a few genius finally put it installed, thanks to Prof. Chang-gun Lee installation suggestions, think that the document may be ready to try to install RTLinux friends have help, my English is very bad, but also lazy, fortunately, not a few pages, try to translate a bit, the need for a friend can see, English good can go to see the original. Overall feeling, RTLinux hardware compatibility is not flattering, the same kernel version, the same configuration on some platforms will not run up, anyway, I tried a intel845g motherboard desktop compatible machine and a SIS motherboard of the Shenzhou mobile PC, the compatibility of a loading RTLinux module on the crash, There is no problem with that country. The man who wrote the original name looks like a Chinese, maybe a Korean. Our normal application is not directly responsive to interrupts and access to hardware resources, it needs to be dispatched by the Linux kernel, but the Linux kernel is not a real-time kernel, the 2.4-core scheduling period is 10ms , the 2.6 kernel can be better, but the real-time is still very poor, the application may be 10ms after the response to a real-time task, so in order to achieve real-time application under Linux, you have to hit the Linux kernel idea, so rtlinux so dry, RTLinux is actually a patch to the kernel, like a trojan to the Linux kernel open the back door, before the Linux kernel to take over the system resources such as hardware interruption, and then according to their own will to allocate resources, can be distributed to the Linux kernel to deal with, can also be assigned to the RTLinux under the loading module, so that the module written under RTLinux may be higher than the priority of the Linux kernel, it can not be directly through the Linux kernel scheduling to respond to a timing or event interrupt, This improves real-time performance. I used the system is Debian, can run up that Hello module, the installation process I mainly refer to his third part of the content, the other parts have not been tested, not guaranteed to use, there are several individuals think some deviation. Okay, good, bad for yourself. Download (in 2007.1.26)
