Take a look at the linuxppc_2.4_devel or some other BK ppc kernels. Start at penguinppc.org for kernel access information. Yes, I know, it shouldn't be in this state, but it is. Find the various kernel sources and peruse for what fits your requirements. Thanks. -- Dan

Thanks for your reply. The PMC card is an SBS palomar II card which I think is a 5v card. No LED's on the card. I have started looking around for a 3pin RS232 cable.

Trying to understand alloc_skb()

You were right about it being trivial. Didnt take me to too long to find the line and saw what was going on. Initially I started reading on how to put the line in process context, but soon I realised its not something you want to spend your afternoon on :P (Currently I dont have too many afternoons for this) Anyway, thanks for the pointer. Actual problem came from rtnetlink.c file where it called rtmsg_ifinfo(). This in turn, called alloc_skb with GFP_KERNEL, rather an GFP_ATOMIC. I guess GFP_KERNEL is right, but what's the difference ? -- Daniel

I'm aware of this problem for quite some time, but chose to keep the current code. This IOCTL implementation has been here for many years in all revisions of the driver, so I think we should keep it as is, because some software could rely on it, and your change will break it. And all new code should use ethtool anyway :). -- Eugene

This should be fixed before attempting to run your system again. I suggest you to seek all smc_scc_num references inside both the console routines and the #ifdef SCC_CONSOLE ... #endif code snippets. They should be subtracted by SCC_NUM_BASE whenever they're used to access SCC-related stuff, AFAIK.

Does this mean the card is fried? Maybe fried, or maybe it's just incompatible with your PCI/PMC adapter. What I/O voltage is the PMC card 5v or 3.3v?

The read/write method is a heavy weight method, while the pointer returned by mmap is light and very efficient way in user-space, and It just works(tm).

Hello Jean-Christophe, That's right, I verify all the useful parameters in my driver and everything seems OK. But, the real question is : if you use the /dev/mem (with open() and mmap ()), could you use, in the user space, the pointer returned by the mmap function to access the physical memory or do you have to use read/write (on the file descriptor) to access physical memory because i haven't the same results according to the used method.

Well, encounter one puzzle on bd_info:-) I use 2.6.11 release package on my custom Sandpoint board with u-boot. In 2.6.11 ppcboot.h, I noticed that there were no CONFIG_8260 but CONFIG_CPM2, which had a conflict with bd_info of u-boot. Does CONFIG_CPM2 means CONFIG_8260 in 2.6.x?

The console code has always been sensitive to configurations.

Hi,
on my target (MPC8270, 2.4.25) SCC1, SCC2 and SCC3 will work fine as ttyS0 ..
ttyS2 with console at ttyS0.
It works with this code in arch/ppc/8260_io/uart.c
#define CONFIG_SERIAL_CONSOLE_PORT 0
#define SCC_NUM_BASE0 /* SCC base tty "number" */
#define SCC_IDX_BASE0 /* table index */
static struct serial_state rs_table[] = {
/* UART CLK PORT IRQ FLAGS NUM */
{ 0, 0, PROFF_SCC1, SIU_INT_SCC1, 0, SCC_NUM_BASE}, /*
SCC1 ttyS0 */
{ 0, 0, PROFF_SCC2, SIU_INT_SCC2, 0, SCC_NUM_BASE + 1},/*
SCC2 ttyS1 */
{ 0, 0, PROFF_SCC3, SIU_INT_SCC3, 0, SCC_NUM_BASE +2}, /*
SCC3 ttyS2 */
Now i need the two SMC's.
I changed the source to:
#define CONFIG_SERIAL_CONSOLE_PORT 2
#define SCC_NUM_BASE2 /* SCC base tty "number" */
#define SCC_IDX_BASE2 /* table index */
static struct serial_state rs_table[] = {
/* UART CLK PORT IRQ FLAGS NUM */
{ 0, 0, PROFF_SMC1, SIU_INT_SMC1, 0, 0},/* SMC1 ttyS0 */
{ 0, 0, PROFF_SMC2, SIU_INT_SMC2, 0, 1},/* SMC2 ttyS1 */
{ 0, 0, PROFF_SCC1, SIU_INT_SCC1, 0, SCC_NUM_BASE},/* SCC1
ttyS2 */
{ 0, 0, PROFF_SCC2, SIU_INT_SCC2, 0, SCC_NUM_BASE + 1},/*
SCC2 ttyS3 */
{ 0, 0, PROFF_SCC3, SIU_INT_SCC3, 0, SCC_NUM_BASE + 2},/*
SCC3 ttyS4 */
and passed the bootloader the correct console=ttyS2.
During booting kernel hangs on initializing ttyS2 forever.
What could be wrong ? I only changed the io port configuration in the init
function.
Thanks in advance

I bought an old powerpc PMC card and a PCI adapter to fit this into the PC PCI slot. However a 'lspci -v' at the command doesn't show any difference with/without the card. Does this mean the card is fried? thanks - venky

That is the console port, so take a look at the code for its initialization for something affected by this configuration. What kernel are you using?

Heh :-) There are lots of permutations of serial ports that probably haven't been tested. You probably found one of them. Thanks. -- Dan

From the Desk of Mr. Paul Kadiri
>From the Desk of Mr. Paul Kadiri
Dear Sir/Madam,
My name is Paul Kadiri, I am a banker with one of the banks
in Lagos in Nigeria. I have urgent and very confidential
business proposition for you. On June 6 2002, a Zimbabwean
farmer/businessman made a numbered time(Fixed) deposited
for twelve calendar months, valued at $15,320,000.00
(Fifteen million,three hundred and twenty thousand united
states dollars-five) in my branch. Upon maturity, I sent a
routine notification to his forwarding address but got no
reply. After a month,i sent a reminder and finally we
discovered from his co-farmer who previously had a joint
account with him in my bank that he died in the land
crisis in Zimbabwe.
On further investigation, I found out that he did not
leave a WILL and all attempts to trace his next of kin
were fruitless. I therefore made further investigation and
discovered that he did not declare any next of kin in all
his official documents, including his Bank Deposit
paperwork.
This sum of US$15,320,000.00 is still sitting in the Bank
and the interest is being rolled over with the principal
sum at the end of each year. No one will come forward to
claim it. According to the Nigerian Law, at the expiration
of 5 (five) years, the money will revert to the ownership
of the Nigerian Government{STATE} if nobody applies to
claim the funds. Consequently, my proposal is that I will
like you as a foreigner to stand in as his next of kin so
that the fruits of this old man's labor will not get into
the hands of some corrupt officials. I will intimate you
with the requirements that the attorney will need to
prepare the necessary documents and affidavits, which will
put you in place as the next of kin upon your positive
response.
We shall employ the services of two attorneys for drafting
and notarization of the WILL and obtain the necessary
documents and letter of probate/administration in your
favor for the transfer. A bank Account in any part of the
world, which you provide, will then facilitate the
transfer of this money to you as the beneficiary/next of
kin. The money will be paid into your account for us to
share in the ratio of 70% for me and 30% for you, There is
no risk at all as all the paperwork for this transaction
will be done by the attorney and my position as the
Regional manager guarantees the successful execution of
this transaction. Upon your positive response,i shall let
you know who i am,the name of my bank and the name of the
deceased.I will also provide you with more details and
relevant documents that will put you in a clearer picture
of this pending transaction.
Please observe utmost confidentiality, and be rest assured
that this transaction would be most profitable for both of
us because I shall require your assistance to invest my
share in your country.
You can email me via this email
address:pakadi13 at yahoo.com
Awaiting your urgent reply
Yours faithfully.
Mr. Paul Kadiri
