Version 1.7-1 of the Dolphin PCI-SCI (Scalable Coherent Interface)
drivers for Linux kernels 2.2 and 2.4 are have been released and

Numerous enhancements have been added to this release, including
enhanced support for X-Y dual fabric SCI rings.

Bug fixes and modifications contained in this release:

IRM 1.10.6 ( March 4th 2001 )

*Genif: Added implementation of SPEEP_OK for sci_create_segment()
*Solaris X86: Fixed build_IRM and added dummy function for hostbridge
manipulation. Thanks to Joachim Worringen.
*2d Torus topology support enhanced ( only for D33x family ) Requres
recompilation of the IRM driver with the ENABLE_MESH_TOPOLOGY_SUPPORT
flag seg. More info in IRM/drv/src/prolog.h.
*VxWorks: Fixed Interrupt registration problem that could cause loss of

IRM 1.10.7 ( April 26th 2001 )

*Added initial entry for Intel i960 support ( not completed ).

and verified on Solaris 7 / ServerWorks. Thanks to Joachim Worringen.
*Added support for 2D torus topology in scidiag.
*Solaris SPARC: Added support for hostbridge detecting D330 as "name=pci11c8,40"

IRM 1.10.8 ( 22th May 2001 )

*Added support for adapter D230 (PSB66 - LC3). A PCI reset will reset the LC3.

*PSB64 not properly supported. Full support from next release again.

IRM 1.10.9 ( 25th May 2001 )

*Code to support PSB64 again added
*VxWorks: Updated to support psb66 ( D33x family ) on PowerPC
*updated sciconfig to set and get link-frequency, prefetch and
no-prefetch space size for more than one adapter.
*Fixed problem for Solaris 2.5.1 in build_IRM, and added exit 1 status
for compilation faults.
*Solaris:Added option for skipping all_build variants in package create

IRM 1.10.10 ( 5th June 2001 )
*Added support for 2D torus up to 15x15 nodes
*Added support for ServerWorks HE idenitying with device id 0x00081166

IRM 1.10.11 ( 19th June 2001 )
*Disabled speculative hold as default for psb66
*Added extra check to make sure that a new DMA transfer (DMA kick) is not
done before the previous DMA transfer has completed.
*Bug fix for 2d-mesh topology using nodeId 200.
*Linux:Added property to reduce mapping of prefetchspace to less than
*Linux: Bigphysarea patch requirement disabled as default for linux 2.4

SISCI 1.10.7 ( 26th April 2001 )
*Added initial entry for Intel i960 support ( not completed ).
*Linux:Enabled MMX intructions support in sciMemCopy()
*Cleaned up and simplified common IOCTL and MMAP code.
*VxWorks: Added support for cache line manipulation for in sciMemcopy,
and added new map flag SCI_FLAG_WRITE_BACK_CACHE_MAP.
*sci ping pong benchmark updated. (SISCI/cmd/test/scipp) Tested on VxWorks/Linux.

SISCI 1.10.8 ( 22th May 2001 )
*Solaris: Optimalization in sciMemCopy().
*Linux: Added flag SLEEP_OK to call to sci_create_segment. Memory
allocaiton thread may now sleep while Linux is allocating memory.
*Linux: Removed erronous DIS/src/SISCI/src/LINUX/os/mmapcode.h
*Linux: Fixed bug in SISCI callback functionality and enabled by default.
*Added implementation of new SCIFlush() SISCI function. Please note that this
function and signature is subject to change.
