Bahadir Balban	cada0f8f18	New UTCB implementation almost working. - KIP's pointer to UTCB seems to work with existing l4lib ipc functions. - Works up to clone() - In clone we mmap() the same UTCB on each new thread - excessive. - Generally during page fault handling, cloned threads may fault on the same page multiple times even though a single handling would be enough for all of them. Need to detect and handle this.	2009-05-01 10:11:47 +03:00
Bahadir Balban	7a81db8782	Ongoing work for adding per-thread UTCB structures. Added setting of utcb address to l4_thread_control. This is going to be moved to exchange_registers() since we need to pass both the utcb physical and virtual address and exregs fits such context modification better than thread_control.	2009-04-29 16:53:04 +03:00

- Works up to clone()
- In clone we mmap() the same UTCB on each new thread - excessive.
- Generally during page fault handling, cloned threads may fault on the same page
  multiple times even though a single handling would be enough for all of them.

Ongoing work for adding per-thread UTCB structures.

Added setting of utcb address to l4_thread_control.
This is going to be moved to exchange_registers() since we need to pass
both the utcb physical and virtual address and exregs fits such context
modification better than thread_control.
