Is printing broke on sparc ?

Is printing broke on sparc ?

[Mr. James W. Laferriere]

	Hello All , On Linux-Sparc I can send data to the /dev/par0 &
	/dev/lp0 but the data appears to be garbled .

	Sending the below printcap to either of the above ports ...
<begin printcap>
# /etc/printcap
#
# Please don't edit this file directly unless you know what you are doing!
# Be warned that the control-panel printtool requires a very strict format!
# Look at the printcap(5) man page for more info.
#
# This file can be edited with the printtool in the control-panel.

##PRINTTOOL3## LOCAL POSTSCRIPT 300x300 letter {} PostScript Default {}
lp:\
	:sd=/var/spool/lpd/lp:\
	:mx#0:\
	:sh:\
	:lp=/dev/lp0:\
	:if=/var/spool/lpd/lp/filter:
<end printcap>

	.. ie:  cat /etc/printcap > /dev/lp0    (or /dev/par0)
	gets me :

/c#eodiecnyotai rhernili s to rpaemn
                                    s eehpo o-.ROLPR0 roif{\=sl:x
                                                                 	/p:ao/lr
	which is where it rolls off the paper .
	printer is a DECLaser 2200  .  I have the PostScript option card
	for it , but when it is installed -notthing- gets output so I
	tried the above experiment without it installed .  With the option
	installed the display shows 'PS Waiting' Then shortly 'PS
	Processing' then 'PS Ready' .  This happens whether I cat .ps
	files or not .  I beleive that something is garbling the data
	being sent .

	I did have this running quite well off of a i386 running linux
	not to long ago .  So I have to be doing something wrong .

	ANy help appreciated .  Tia ,  JimL

This looks like characters are getting missed out, rather than
anything getting garbled.  The above characters all appear in
/etc/printcap in the order shown.  Obviously there isn't enough
redundancy in /etc/printcap for the print-out to be useful despite
that. :-)

Please try adjusting the 'udelay (1)' lines in
drivers/parport/ieee1284_ops.c:parport_ieee1284_write_compat to be
larger delays (for example, try replacing the 1s with 2s, or 5s, and
see if that makes things better).

Let me know what you need to change to get it working.

Thanks,
Tim.

	I am going to look and see if there might be a ioctl for that
	function .  Failing that I shall recompile the kernel with each
	of those values & test until successful or it seems futile .

	Ok , There isn't a sysctl available to do that .  I am also a
	little worried about the 'none' in ths below .

root@udragon:~# sysctl -A | grep -i parp
dev.parport.parport0.devices.active = none
dev.parport.parport0.modes =
dev.parport.parport0.dma = -1
dev.parport.parport0.irq = 6814784
dev.parport.parport0.base-addr = 2198696099840	0
dev.parport.parport0.spintime = 500
dev.parport.default.spintime = 500
dev.parport.default.timeslice = 200

	But I do see timeslices in the 'lp' of /proc/...
dir /proc/sys/dev/parport/parport0/devices/lp
total 0
   0 dr-xr-xr-x    2 root     root            0 Apr 17 17:26 ./
   0 dr-xr-xr-x    3 root     root            0 Apr 17 17:26 ../
   0 -rw-r--r--    1 root     root            0 Apr 17 17:26 timeslice

	Off to build 3 kernels on this old tub .  Twyl ,  JimL

Don't be: unless the printer driver is actually using the port at the
instant that you look at the sysctl, it'll say none.  It's normal.
If you are printing at the time you look, keep checking sysctl and you
will see 'lp' there sometimes.

	Tries both 2's & 5's , Both did the leaving things out .  Although
	in a differant pattern with each .  Am going to try 10's next just
	for grins .   Twyl ,  JimL

kernel2.2.x to kernel2.4.x

[jalaja devi]

I tried porting a network driver from kernel2.2.x to
2.4. When i tried loading the driver, it shows the
unresolved symbols for
copy_to_user_ret
outs
__bad_udelay

Could anyone please tell me the corresponding fxns in
2.4.

Thanks in advance
Jalaja

	Has not gone away, your includes are wrong

	You are using too large a udelay use mdelay

Re: kernel2.2.x to kernel2.4.x

[jalaja devi]

How can I handle this from kernel2.2 to kernel2.4

Can I replace like this??

if (test_and_set_bit (0, (void *)&dev->tbusy)){ return
EBUSY;} ========== with  netif_stop_queue (dev);

clear_bit ((void *)&dev->tbusy); ===== with
netif_start_queue(dev);

Thanks
Jalaja

You need to "unroll" copy_to_user_ret().  There is no
corresponding macro.  Just test the condition and return
-EFAULT (?; not looking at the source code) if it's invalid.

Don't know about "outs".

__bad_udelay means that some module used a too-large-parameter-value
to udelay().  Linker should be telling you which module.
