These patches contain the following linux kernel features:
Summary:
New device driver: CTCMPC
Description:
The CTCMPC driver implements CommServer SNA MPC connectivity.
Summary:
Dasd new function: Added 2107 and 1750 CU-types.
Description:
The DASD driver now tolerates the new Control-Unit-types (CUs)
introduced by the DS6000 and DS8000 storage server family.
The new CU-types 2107/1750 are handled the same way as
CU-type 2105 and there is no additional feature / ERP handling
related to these CUs.
Summary:
Dasd new function: fixed I/O buffers.
Description:
This feature limits the number of pages referred by channel
programs. It can be enabled by using a new keyword 'fixedbuffers'
on the 'dasd=...' parameter.
Example: dasd=0.0.7000-0.0.7002,fixedbuffers
When the new feature is enabled it applies to all ECKD and FBA
disks, but not to disks that are accessed using the DIAG
discipline.
To check whether the parameter was recognized correctly you can
check the boot messages. When the fixed I/O buffers were
enabled successfully you will find the following line in the log:
dasd_devmap: turning on fixed buffer mode.
