* linux @ xup

Hi
I already succeded in setting up a Linux for the ml310. I'm trying to do it for the XUP Board now. The Problem I have is, that
in every HowTo I read I should set at the EDK's software settings under Library/OS Parameters:
Set PLB_CLOCK_FREQ_HZ to the PLB speed (usually 100000000)
But I can't find where to set it. With the ml310 there was this option. I'm using the EDK Board Definition File (.xbd), Pcores & Drivers from Xilinx:
http://www.xilinx.com/univ/xupv2p.html
EDK Version 9.1 SP2
If I ignore it and build the BSP there comes out an xparameters_ml300.h file which I copy to my Kernel sources.
When I try to compile, I get errors that the PLB_CLOCK_FREQ_HZ isn't defined.
Can I just add it to the xparameters_ml300.h file file (which I rename "xparameters_xupv2p.h") by Hand?
Greez and thx
Joachim

Ups, good catch. I've put a spin_unlock() / spin_lock() around it and
moved the _irqrestore down below now.

It can be null in c67x00_check_td_list, so it's actually the comment
that's wrong. I've fixed that.

Ahh, so should I just unconditionally do the unlink_urb_from_ep and

Hmm, I don't actually remember anymore. It's was written back in
Spring 2006 by Jan. I'll try moving it out of the tasklet and see what
it gives.

Ahh, ofcause.

* PCI configuration with multiple PCI controllers
From: Laurent Lagrange @ 2008-01-30 8:37 UTC (permalink / raw)
To: linuxppc-embedded
Hello,
I have a MPC8641 based board. I try to use the two PCIe controllers. My
firmware configures (physically) the PCI buses as follow:
------------------+
MPC8641 PCIe 1 | bus 1 +--------------+
| --------------> | PCI device 0 |
BUS 0 | +--------------+
- - - - - - - - - +
MPC8641 PCIe 2 | bus 3 +--------------+
| --------------> | PCI device 1 |
BUS 2 | +--------------+
------------------+
I launch the Linux image (2.6.23.9). During the Kernel PCI configuration,
buses behind the 2nd MPC8641 PCIe are skipped because its primary bus don't
start at bus number 0. The kernel reconfigure the primary bus number of the
MPC8641 PCIe 2 controller from 2 to 0.
I can patch the kernel to work with my firmware but I don't know if my PCI
configuration is the good one.
What is the common way to configure the PCI for Linux when a new controller
is found: start the bus number to 0 or to the last bus number + 1?
Regards
Laurent

Seems OK to me, but I feel I don't have enough knowledge to ACK or NAK.
Please pass through an arch tree, thanks.

How about this patch? Ben, if you think this is ok then we should make sure
that it goes in in this merge-window, since the other dts patch relies on it.

Hi Jeff,
The patch set I posted on Dec 13 2007 (except v2 of #6) have been
reviewed on the ML and seems to have no more outstanding
comments/requests.
http://marc.info/?l=linux-netdev&m=119754603814092
Is it OK to apply for 2.6.25? If OK, I'll ask Paul to merge this set
into the powerpc tree with my wireless patch because the dependent patch
set will go into the tree.
best regards

The reason that we check for !p after assigning node id is that, in
case we create fake NUMA nodes, we want nid to be the fake numa node
id and not the real node id or in the non NUMA case, node id 0.
The if (!p) checks to see if we do have more arguments to parse.

* 83xx HDLC Driver Dev - Multiple PHYs?
From: Russell McGuire @ 2008-01-30 5:10 UTC (permalink / raw)
To: 'Andy Fleming'; +Cc: linuxppc-embedded
In-Reply-To: <D71D9F25-4724-487E-AD07-E848B4608B97@freescale.com>
All,
I have gotten my HDLC driver up to the point where it can register itself
with the Linux kernel. However now I am faced with a dilemma and style
question, that is probably best answered by you driver developers that have
more experience.
I am putting support for multiple PHY's into the HDLC driver, but after
converting it to use the of_device tree, and inserting a UCC@5000 for a
single UCC HDLC driver, it occurred to me that if I insert more devices
(UCC@6000, UCC@7000, UCC@8000) that the driver will attempt to load multiple
times.
So here is the question.
Solution 1:
Should I develop the system to have a single ucc@xxxx entry in the
platform.dts file and have a field(s) like phy-count=<4>, to support
multiple devices? And have each instance of the module contain private data
for one UCC, interrupt handling, etc...
OR
Solution 2:
Is there a way to have a module know if it has already been loaded, so it
doesn't insert multiple times and then play the rest like Solution 3?
OR
Solution 3:
Have phy-count=4; defined in the driver header, or a module parameter, and
have a single module instance of the driver itself responsible for creating
a single private data structure and setting up multiple UCC's and PHY's?
This also feeds into a question on SET_NETDEV_DEV. How does it react to
multiple net devices attached to a single base driver?

[-- Attachment #1: Type: text/plain, Size: 756 bytes --]
Hi,
I have to port one customised layer 2 protocol stack and read, write system
call to access devices in linux-2.4.
At the moment this is ported in UNIX SVR2/4 operating system.this protocol
uses some common data structure,
i.e "user" in unix srv2/4, which keeps information such as
u_error = return errorn code
u_base = base address for I/O
u_count = bytes remaining for I/O
u_arg = argument to current system call etc.
so i need to store these information in linux-2.4 implementation for
implementing read/write system calls.so what is/are
corresponding structure in linux-2.4.i went through task_struct, fs_struct,
files_struct etc., but couldn't relate it properly.
Please help me on this .
thanks and regards,

Right.
Currently, our machine doesn't have real physical remove feature yet.
(only add).
So, I think testing is not enough around physical removing.
Probably, your box will be first one which can remove physical memory
with Linux. It is good for testing.
If you notice anything, please let me know. :-)

For addresses going from the CPU to the bus, RAM is occupying everything
from zero to SIZE_OF_RAM, while PCI MMIO starts at LARGE_NUMBER+2GB.
As seen from the PCI bus, DMA addresses for RAM range from zero to 2GB,
while the MMIO space is between 2GB and 4GB. The 64 bit space for
the linear mapping is between EVEN_LARGER_NUMBER and
EVEN_LARGER_NUMBER+SIZE_OF_RAM.
The bridge chip remaps EVEN_LARGER_NUMBER to zero when going into the IOMMU,
so that the IOMMU can fit both SIZE_OF_RAM and the dynamic DMA window
into the 32GB bus address range.
I don't see how it should be possible here to reuse the 2-4GB range
for anything else.
