[U-Boot-Users] watchdog reset in mpc824x timer interrupt.

[U-Boot-Users] watchdog reset in mpc824x timer interrupt.

[Gleb Natapov]

Hello,

 Attached patch makes timer_interrupt to perform watchdog reset on all
boards that support watchdog and not only for OXC.

CHANGELOG:
perform watchdog reset in mpc824x timer interrupt on all boards that have watchdog.

Thanks, added. Will show up on CVS "soon" :-(

[U-Boot-Users] watchdog reset in mpc824x timer interrupt.

[Gleb Natapov]

Hello Denk,

I've looked at timer_interrupt() on all Motorola CPUs and it seems it is
possible to move most of the code from cpu/$(CPU)/interrupt.c directory to 
one common place (ppc_lib/interrupt.c for instance). Unfortunately I have only
MPC8245 CPU for testing.

I can test on 8xx and 82xx.

[U-Boot-Users] watchdog reset in mpc824x timer interrupt.

[Gleb Natapov]

Hello Wolfgang,

 The attached patch moves most of the things related to timer interrupt to
ppc_lib/interrupts.c leaving only cpu specific code in cpu/$(CPU)/interrupts.c

I only checked it on MPC8245. It works for me.

Can you look at the patch please.

CHANGELOG:
Move most of the things related to timer interrupt to ppc_lib/interrupts.c

Best regards,

[U-Boot-Users] watchdog reset in mpc824x timer interrupt.

You do much more than just this. I appreciate most of  your  cleanup,
but I have a few requests:

* Please don't  create  a  new  (and  undocumented!!)  config  option
  CONFIG_ACTIVITY_MONITOR  -  we  already  have  CONFIG_SHOW_ACTIVITY
  which serves exactly this purpose. I see no need for a new option.

* Instead of just collecting common stuff in a common file you change
  interfaces here and there. Can you please describe  these  changes,
  and the reasons for them.

* Please keep existing Copyright notices in place.

Can you please rework your patch and resubmit it? Thanks.

Best regards,

Wolfgang Denk

If you fail to plan, plan to fail.

Yes CONFIG_SHOW_ACTIVITY is exactly what I need. I didn't find it first time. Thanks.

I don't quite understand what interfaces I changed. But I can explain how I see it working
now.

There are common interrupt_init() and timer_interrupt() for all PPC archs.
interrupt_init() calls interrupt_init_cpu() for cpu specific initialization.
interrupt_init_cpu() should set decrementer_count to appropriate value. If
cpu resets decrementer automatically after interrupt (ppc4xx) it should set
decrementer_count to zero.
timer_interrupt() calls timer_interrupt_cpu() for cpu specific handling.
If board has wahtchdog/status_led/other_activity_monitor it works automatically
from general timer_interrupt().

I hope new patch contains proper Copyright notices in place.

[U-Boot-Users] watchdog reset in mpc824x timer interrupt.

[Gleb Natapov]

Hello Wolfgang,

 What is the status of my patch that combines common functionality
of timer interrupt in one place for all PPC boards. Is it rejected, accepted
or needs more work?

 Thanks,

Let's say it's on hold. I think I will accept it, only not  for  this
but for the next release.

Hi

Did anyone try to add support for interrupts for the 74xx_7xx ???

Thanks Ronen
