Hi all, I have completed reading the LLD3 and The Design of Unix Operating Sysem. I have just started writing my own version of LLD example drivers. My machine runs on FC8.
Theoritically, understand that the buffercache only avialable for Block driver not char devices. I wrote a scull type char driver. I do this from the APP: fwrite(buf, 1, 2, fd) rewind() fread(buf, 1, 1, fd) fwrite(buf, 1, 1, fd) During the fread operation, driver gets a read of 4096 bytes from the application whereas the application is trying ot read only 1 byte. This looks like file system buffer cache.???
