PA-RISC Linux supports all HP PA-RISC workstations. Not everything is
+
perfectly functional - but nearly all of it works. The unlettered 700-series
+
workstations (eg 712/715/735) and the B/C/J class machines (eg B132L, Tadpole B160L laptop, C180L,
+
C200, C3000, J5000) systems are supported. Fast-Wide Differential SCSI does
+
not work on 735 or 755 (but does on other machiines).
+
Most standard HP graphic cards work (Visualize-EG, Artist, HCRX, ...) in 8 and 24bpp modes.
+
Support for the Vis-FX series is still missing. A few issues remain with Frame Buffer (graphics support)
+
on some machines (eg C3000/J5000) with a 64bit Linux Kernel but are being worked on.
+
 
+
PA-RISC VME boards are based on workstation designs.
+
PA-RISC Linux does boot on a 743.
+
 
+
Please submit bugs (or patches!) for missing/broken functionality
+
to the parisc-linux [[mailing lists]].
+
 
+
== Servers ==
+
+
The earliest PA-RISC servers have proprietary HP devices attached to
+
proprietary HP bus architectures. Documentation on these busses and
+
devices will not become available soon since no one in HP is finding,
+
"scrubbing", and releasing the docs.
+
Machines in this category are the F, G, H, I class (aka Nova) and
+
T500 series (Emerald) machines as well as some earlier, unlettered servers.
+
 
+
The T600 is unlikely to ever be supported. Though T600 uses some of
+
the same GSC devices (eg card-mode Dino 100BT, Zalon FWD SCSI) as
+
K-class, T600 has the Java I/O MMU, instead of U2, which is NOT I/O
+
coherent. Linux PCI drivers require I/O coherency.
+
 
+
Support for the E class is being pursued. Similar to K class in some
+
ways, it requires the Mux driver for console and does not yet have SCSI
+
or Centronics support. Network support is the same as 712. GSC add-in
+
cards should work, HP-PB cards will not yet.
+
 
+
The D, K and R class machines are at least partially supported.
+
These machines are architecturally similar to the older B, C and J
+
class workstations and share most of the I/O devices, busses (GSC)
+
and processors. The console on K class and the optional console card on
+
D/R class are now supported. Most of the other HP-PB (aka NIO) devices
+
aren't supported due to lack of documentation -- the same documentation
+
which makes the Nova/Emerald machines unsupportable.
+
 
+
The A180, L1000/2000/3000, N4000, and A400/A500 servers are supported.
+
Support for Superdome will someday follow but requires some
+
additional VM work which is in progress.
+
 
+
People ask about V-class. V-class has a very different architecture
+
from other HP machines. See the
+
[[Server Architecture Reference]]
+
for details. One major known problem with supporting V-class is
+
the complexity of its PCI bus adapter (EPIC and SAGA).
+
Support for the V-class isn't going to happen until some really
+
masochistic person who has access to a V-class is, uh, challenged by this.
+
 
+
A list of currently supported hardware is maintained by the ESIEE Team, you
+
should take a look [[here]] for any precise material.
