Hi Scoot,
When I try to use a atomic varaible in my ISR I see a kernel crash . with
mesage BUG: scheduling while atomic:
Below is the code :
My ISR

{

Hi Scott,
I am able to register the IRQ now once I add the call irq_set_default_host in
cpm2_pic.
But when I call enable_irq the code throws the below warning and gives
exception in enable irq at
spin_unlock_irqrestore(&desc->lock, flags); in enable_irq.

This patch adds support for GXT4000P and GXT6500P cards found on some
IBM pSeries machines.
GXT4000P/6000P and GXT4500P/6500P couples are identical from
software's point of view and are based on the same Raster Engin
Hi Jorg,
you submitted the patch slightly modified by Acrux (from CruxPPC) [1]
Anyway this patch is widely used by any ibook/powerbook owners with
great satisfaction.
I also use this patch from Jan 2011 and i'd like to see it upstreamed.
Btw, guess you should add:

Smitha,
Do you have the entry of this device node in your DTS file?
if yes, then is the device is getting registered properly?
If you are writing platform driver then you can use 'platform_get_irq'
it returns the irq number,
which you can pass in the 'request_irq'. If it is a simple character

The RTAS firmware flash update is conducted using an RTAS call that is
serialized by lock_rtas() which uses spin_lock. While the flash is in
progress, rtasd performs scan for any RTAS events that are generated by
the system. rtasd keeps scanning for the RTAS events generated on the
machine. This is
Hi Scott,
Thank you. But I am not very clear where exactly I need to call the
irq_set_default_host().
And also for the second fix I did not understand or to make cpm2_pic_host
non-static (in which case you should pass that).
in th previous mail what exactlyy you mean.
Thanks & Regards,
Smitha
