[okl4-developer] thread spaceid

[Harry Vennik]

I have run into the same thing recently. Not often a thread needs to  
know its own space-id, but when implementing some memory management  
server it would be very nice to be able to map the thread-id where  
the IPC request is coming from to a space-id to apply the memory  
mapping to. I think the microkernel simply has to keep track of the  
thread to space relations, so why require a memory manager server to  
do the same thing? I think it would be better to keep that info in  
the micro kernel only, and provide a way for the memory manager to  
request that information through a (privileged) syscall.

Regards,

Harry
