Kernel installation
------------------------------

<kernver> = version of mainline Linux kernel
<ckrmver> = version of CKRM

Note: It is expected that CKRM versions will change fairly rapidly. Hence once
a CKRM version has been released for some <kernver>, it will only be made
available for future <kernver>'s until the next CKRM version is released. 

1. Patch 

    Apply ckrm/kernel/<kernver>/ckrm-<ckrmversion>.patch to a mainline kernel
    tree with version <kernver>. 

    If CRBCE will be used, additionally apply the following patches, in order: 
       delayacctg-<ckrmversion>.patch 
       relayfs-<ckrmversion>.patch
    
 
2. Configure

Select appropriate configuration options:

a. for taskclasses 

   General Setup-->Class Based Kernel Resource Management

   [*] Class Based Kernel Resource Management
   <M> Resource Class File System (User API)
   [*]   Class Manager for Task Groups  
   <M>     Number of Tasks Resource Manager

b. To test socket_classes and multiple accept queue controller 

   General Setup-->Class Based Kernel Resource Management
   [*] Class Based Kernel Resource Management
   <M> Resource Class File System (User API)
   [*]   Class Manager for socket groups
   <M>     Multiple Accept Queues Resource Manager    
   
   Device Drivers-->Networking Support-->Networking options-->
   [*] Network packet filtering (replaces ipchains)  
   [*] IP: TCP Multiple accept queues support

c. To test CRBCE later (requires 2a.)

   File Systems-->Pseudo filesystems-->
   <M> Relayfs filesystem support 
   (enable all sub fields)
   
   General Setup-->
   [*] Enable delay accounting
   

3. Build, boot into kernel

4. Enable rcfs

    # insmod <patchedtree>/fs/rcfs/rcfs.ko
    # mount -t rcfs rcfs /rcfs
 
    This will create the directories /rcfs/taskclass and
    /rcfs/socketclass which are the "roots" of subtrees for creating
    taskclasses and socketclasses respectively.
  	
5. Load numtasks and listenaq controllers

    # insmod <patchedtree>/kernel/ckrm/ckrm_tasks.ko
    # insmod <patchedtree>/kernel/ckrm/ckrm_listenaq.ko
