Hello All,
I have mpc8313erdb evaluation board and currently I am writing GPIO
driver. Actually it is just simple test driver.
I did the irq_request in the driver init function, as request_irq
returns zero (0) if successful, otherwise -1 on error and errno
indicates the error. But when I load or

Thanks for your prompt reply ...
I am using kernel version 2.6.20 ...
May I know what raw IRQ means ? ? ? and what is the reason I cant map
raw_irq_number ???
Kindly please acknowledge ... thank you ...
Kind Regards,

OK, that kernel has the irq remapping stuff.

Sorry, that's not the best
Ok ... so that means if I am writing driver for any device I need to
take care of this mapping ? ? ? I mean I should use virq ? ? ?
I read in LDD book, they give directly irq no. they have given
parallel port example, here they have set or said irq no. defaults to
7 and they have not done any irq_

Folks,
Does somebody have RT patch for 2.6.11? I cannot find it anywhere.

Add a new member topology_ready to the powerpc machdep_calls
structure.
The NUMA hot plug memory routines require the NUMA node to have
been registered via register_one_node() prior to adding memory
to the node. The powerpc arch registers NUMA nodes during
startup in its topology_init() routine.
Switch the PS3 hotplug memory routine ps3_mm_add_memory() from
being a core_initcall routine to being called via the new
topology_ready powerpc machdep call.
core_initcall routines run before the powerpc topology_init()
startup routine, resulting in failure of ps3_mm_add_memory()

The TOCS used by modules are different than the one used by
the core kernel code. The function graph tracer must save and
restore the TOC whenever it traces a module call. But this
is an added overhead to burden the majority of core kernel
code being traced.
