27 Console (HMC) - based system management.
30 on an appliance server named the Hardware Management Console (HMC),
32 Power Systems environment, a single HMC can manage multiple POWER
46 traditionally require an HMC can be implemented in the management
47 application using a combination of HMC to hypervisor interfaces and
49 functions implemented by the HMC and enables basic partition configuration.
50 The set of HMC to hypervisor messages supported by the management
84 communicate capabilities to their partner. HMC Interface messages are used
85 for the actual flow of HMC messages between the management partition and
86 the hypervisor. As most HMC messages far exceed the size of a CRQ buffer,
87 a virtual DMA (RMDA) of the HMC message data is done prior to each HMC
121 initial pool of VMC buffers, one buffer for each possible HMC connection,
137               ADD BUFFER (HMC IDX=0,1,..)         _
145 After the basic VMC channel has been initialized, an HMC session level
147 the VMC device and executes an ioctl() against it, indicating the HMC ID
150 new HMC session value (ranging from 1 to 255) and HMC index value (starting
151 at index 0 and ranging to 254) for this HMC ID. The driver then does an
152 RDMA of the HMC ID to the hypervisor, and then sends an Interface Open
155 management partition to seed an initial pool of buffers for the new HMC
163         	      RDMA HMC ID
178 exchange HMC messages via the Signal VMC message and RDMA operations. When
208 HMC session level connections are closed by the management partition when
212 storage allocated for buffers for this HMC connection.
