24 ### Version 1.1 of the Universe Driver now supports Kernel Versions 2.4...
25
26 Check www.vmelinux.org for examples of Interrupts and DMA transfers.
27
28 We are eagerly waiting to see how well the 2.6 Kernel handles interrupts from
29 user processes. This may well change everything. Stay tuned.
30
31 What you find here are files that will allow the Linux Kernel access to the
32 VMEbus in computers that use the Tundra Universe CA91C042 PCI-VME bridge chip.
33 Used by many processor manufacturers, the Universe is a proven performer
34 in VME bus access.
35
36 This version of the VMELinux Utilites will only work with the 2.2.x and 2.4.x
37 Linux kernels due to the many changes in kernel structure since 2.0.x. Also,
38 you must have the GNU 2.8.x or newer compiler.
39
40 Please keep in mind that GCC 3.0 is a major change from GCC 2.95 compilers.
41 There maybe problems with using GCC 3.0 but it does seem to work on our
42 systems.
43
44 Yes, we do interrupts. The Universe driver installs as a kernel module making
45 its functions available to other kernel modules. User mode interrupts are not
46 supported. Very soon an example program will be available to show all of you
47 how to deal with VME interrupts using the Universe ca91c042 driver. Please
48 visit the VMELinux Project web site www.vmelinux.org and join the email list
49 to keep up with the latest developments.

51 The VMELinux Project works on:
52
53 Dynatem DPC1,
54 SBS Or-Computer VP7,
55 XyCom
56
57 and other processors. As we test more boards we will list compatible models
58 on the web site.
