One of the major feature goals for 3.0 is the transition to the new
CAM-inspired SCSI subsystem. This transition requires a hard cutover
date.
The proposed cutover date is the 28th of April. On or about this point
in time, the following steps will be taken:
- A CVS tag will be applied to mark the last checkout date prior to
the cutover.
- The CAM code will be committed to the -current branch.
- GENERIC and LINT will be translated to suit.
- MAKEDEV will be updated.
- Non-CAM SCSI code and drivers will be *disabled*.
There will be an announcement at least 24 hours preceeding the cutover.
It is important to note that the cutover to CAM will result in a number
of SCSI adapters and devices becoming *unsupported*. A number of these
are significant items, and developers are encouraged to take the time to
update drivers which they may have an interest in. FreeBSD Test Labs
will endeavour to provide loan equipment to developers undertaking such
updates.
The following SCSI adapters will become unsupported:
Driver Adapter Owner
------ ------- -----
aha Adaptec 1542 ? (*)(+)
aic Adaptec aic6x60 ? (*)(+)
amd NCR 53c974 ? (*)
dpt DPT RAID controllers Simon Shapiro (*)
nca NCR 53c400 ?
sea Seagate ST01/ST02 ?
uha Ultrastor 34F ? (*)(+)
vpo Iomega ppa3 (eg. Zip) Nicolas Souchu (*)(+)
wds Western Digital WD7000 ?
The following SCSI peripherals will become unsupported:
Driver Adapter
------ -------
od Optical-disk device (*)(+)
uk Unknown SCSI device
worm Write-once SCSI device
Drivers marked (*) are considered to be currently supported, and
desirable for 3.0.
FreeBSD Test Labs has development hardware available for loan to
developers for drivers marked (+). In some cases, documentation may
also be available.
If there are any significant issues (other than FUD) relating to the
proposed cutover, now is the time to raise them.
Followups should be directed as follows:
