PCI memory alloc..!
Hi all, While I was trying to track to find out how a device alloc a new memory resource, I have been little confused on finding out how the new PCI device can deal with a case when the activation calls pmap_mapdev What I need to understand that what will happen if pmap_mapdev allocated a new space that dose not match what is expected by the device and determined by r_start and r_end ??

printf...! and BSD
Hi, First of all, Thanks to all of you for your help and support. I have tried to go deeper and deeper to find out how "printf" works. ((( Of course the aim of trying to understand the "printf", is to understand how the internals of the BSD kernel work))) till i've faced the following function: "fo_write" which was confusing for me =) Then, I've figured out that i need to understand two important things in the BSD to know how the "printf" works. The first thing is how dose the device driver works, and the second thing is the file system, and small knowledge about the process structure. I will try to do that, but which resources can help me. For Linux, there are two great book which can make my life easier "FOR LINUX ONLY" 1.UNDERSTANDING THE LINUX KERNEL. 2.LINUX DEVICE DRIVERS. Now what resources you can recommend for me! I prefer Internet resources.

printf....!
Hi all, I was trying to know how "printf" works in FreeBSD... I hvae reached to this point : #define _write(fd, s, n) \ __syscall(SYS_write, (int)(fd), (const void *)(s), (size_t)(n)) I'am not really familiar with the way FreeBSD handle interrupts. I like from any one of you to tell me what functions will be called next and in which files, till we get the string of the printf function argment displayed in the terminal.
