Here we put design features that everyone agree
 
* resources are:
 
** kernel memory
 
** total length of unreclaimable mappings
 
** physical pages
 
* each resource group is independent from each other
 
 
 
; unified interface for mem, cpu, disk I/O
 
: It is still not clear whether we need unified interface.
 
: Having one syscall for setting values for different resources seems OK if leaving alone the meaning of the "value" notion.
 
 
 
; memory reclamation
 
: Pending to be implemented on top of BC.
 
 
 
; moving tasks across beancounters
 
: Required changes:
 
# saving bc on vma instead of mm
 
# can two threads in a process be in different BC contexts?
 
# changing mm->bc in set_bc_id().
 
 
 
; what is implied by the term "guarantee"
 
# container will be able to touch that number of pages - I think this one (Hansendc)
 
# container will be able to map that number of pages
 
# container will not be killed unless it touches that number of pages
 
# anything else
 
 
 
; make it possible to charge full user page to its allocator and keep it charged till unmapped
 
 
 
; Consider creating resource groups via the use of aggregation (aggregated BC)
 
 
 
== Top Level Design - thoughts on how to accomplish the goal ==
 
# Create a BC per thread group
 
# Associate a group of BC's with an aggregated BC (we can call this a BC resource group)
 
# Enable migration of tasks by charging and un-charging aggregated BC when a BC moves across from one aggregated BC to another
 
# Change set_bcid() to create aggregated BC's instead of BC's
 
 
 
== Accounting information ==
 
# Is it possible to merge vm_acct_memory() with the accounting information in beancounters?
