[parisc-linux] palo, update to README.INSTALL

[parisc-linux] palo, update to README.INSTALL

[Paul Bame]

palo's command line has changed since README.INSTALL was written, so
if you have a newer palo (for example
ftp://puffin.external.hp.com/pub/parisc/binaries/userspace/palo-20010118.tgz)
please note this change.

Where README.INSTALL uses 'palo -I -k ... /dev/sda' please change it
to 'palo -k ... -I /dev/sda' -- the -I option now requires an argument.

And need to add "console=ttyS0" parameter too!

I'm using CONFIG_SERIAL_CONSOLE on c3k:
    palo -I /dev/sda -k /boot/vmlinux -b /boot/iplboot \
         -c '3/boot/vmlinux console=ttyS0 TERM=linux HOME=/ root=/dev/sda3'

A little update for STI users

If you want to use the STI-console this parameter become              
"console=tty"                                                         
And do not forget to update the /dev/console too!

[parisc-linux] C100 and newest CVS bits

[Greg Ingram]

I checked out the newest CVS bits and built a new kernel that dies on my
C100.  Serial console seems to be working better though.  It's dying in or
right after the SCSI setup.  The tail of the boot messages is below.  Both
of my disks were working with an earlier kernel.  Any suggestions?

Bogus ASSERT. Ryan committed the fixes last night. Please try again.

I pulled ccio-dma.c again and it still has the ASSERT at line 738.  If I
remove it, the kernel dies at line 385:
	
	ASSERT(pages_needed);

If I remove it, death occurs are line 460:

	ASERT(pages_mapped);

I've appended messages again.  Is the message from sim700 important?  Or
is it just telling me that I don't have that hardware?  The very last line
is different too.

My bad. My brain thought that was a different ASSERT.

Ok.  Is this a SCSI problem or a ccio-dma problem?  Like I mentioned
earlier, both disks worked with the kernel sources I downloaded last
week.  I've got all of SCSI disabled and the current kernel is running
fine.

That lot was from sim700, and is ok.

We are now entering the zalon (ncr53c8xx.c/zalon.c) driver.

Now we are probing the sim700 scsi bus

Now we are probing the FWD (zalon) scsi bus

Now the system will try to access these disks looking for partition
tables.

Your original message (assert size > 0) implies that one of the scsi
drivers has passed down a request to map a zero length buffer.  That
is quite possible - a Test Unit Ready will likely have a zero length
buffer as there is no data phase, and a driver might just try and map
it anyway.  I'll have a look at the drivers shortly.  I cant explain
why it used to work though, unless previous versions of ccio-dma.c
handled zero length requests differently.

cvs log of ccio-dma.c explains:
revision 1.21
date: 2001/01/16 03:19:50;  author: rbrad;  state: Exp;  lines: +857 -457

- Added support so the ASSERTS actually work.

That was indeed the case.  Something asks sim700.c to do a bidirectional
trasfer of length 0.  Fixed sim700.c to not pci_map_single() on such
requests.  Should be ok now.

[parisc-linux] [PATCH] typo fix

That patch I sent last week has a letter O instead of a zero in the 'C100'
string in the comment.  Only one.  What were my fingers doing?

Greg,

I can apply this patch if it really bothers you :)

Otherwise I am hoping to have the hack removed out of the ccio driver
with in a week.  I have already taken it out of my local tree, and just need
to finish up one small part of the I/O tree before committing it.
