MontaVista 2.6 Kernel support for Xilinx ML40x

MontaVista 2.6 Kernel support for Xilinx ML40x

[Frank D Lombardo]

I noticed that MontaVista now has their Pro 4.0 version (2.6 Kernel) 
available for the Xilinx ML40x series of boards.  I would assume that 
means driver support for at least most of the hardware on the boards.  
Is this code that should be freely available?  How would one get a copy 
of these drivers?  I am interested in drivers for the ML403.

Thanks,
Frank

Frank,

due to my understanding of the GPL (and i have already invested some =
time
in understanding the various flavours of open source licences), you =
should
contact Montavista, and ask them for the sources.

This board adaption is derivative work of the GPL Kernel, so the result =
of
this work also falls under the GPL, and has to be made freely available=20
under the terms of the GPL.

I too had high hopes when I heard an LSP for the ML40x was imminent, I
nabbed it and was disappointed to find that their drivers still only
support relatively old versions of the Xilinx IP.  It would seem that
they are still creating the design they ported to with EDK/ISE v7.2
rather than the newer 8.1 or 8.2 with updated IP libraries.  This is
from the xparameters_ml40x.h file they distribute.

  I've got the LSP, and have booted it on the ML40X.

  In my opinion it is currently unstable, but that is my opinion.  I've not
been able to keep it powered up for 24 hours without it locking up on the
RS232 serial terminal.  Also, running updatedb over nfs causes it to abort
with a kernel panic, although that might be an interraction with the nfs
server.  (Although even if the nfs server dies (which it did not), I don't
expect a kernel panic).

   I have had it run over 6 hours without issue, so I expect subtle memory
leaks, not serious problems.

RE: MontaVista 2.6 Kernel support for Xilinx ML40x

[Rick Moleres]

Note that Xilinx plans to update the MV drivers to support the latest IP
in EDK 8.2.2 (due out around October), and these drivers would be part
of the BSP generation process of Platform Studio.  Sorry, the timing of
the MV ML40x work and our EDK 8.1.x release was such that MV had no
choice but to use older IP and drivers.

Wade,

are you sure that you did not build your hardware with evaluation cores 
of the licenses? If you are using the evaluation licenses the hardware 
(FPGA design) will stop working after a certain amount of time and you 
will see a lock-up.

Good question.  How long before lockup?  The only core that should be
licensed is the ethernet, and I know it was sysgened on a system with a
license.  This is the Xilinx reference design for the ml403 board.

Re: MontaVista 2.6 Kernel support for Xilinx ML40x

[Frank D Lombardo]

The ml403 reference design has several evaluation cores: opb_uart16550, 
opb_iic and opb_ethernet.  They seem to time-out after about eight hours.

When we were using the eval version of Xilinx's 10/100 EMAC it would time-
out after 8 hours (and the kernel would panic since our root fs was NFS-
mounted).

If your only [to-be-]licensed core is Ethernet, then I take it you're using
the UARTLite, or a non-Xilinx UART?  We used Xilinx's 16550-compatible UART,
which is licensed, but I never ran with the eval version of that IP block
and so have no idea how long it will function before shutting down.
