Requesting specific memory adress

[Kristoffer E. <kri...@gm...>]

Greetings,

We are testing a new way of doing suspend on the hp6xx (&hp7xx) but in order for this to work I need to set aside a certain adress where suspend->return adress is stored. Now, is it possible to grab this memory specificly?

Set it up as a resource and flag it as IORESOURCE_MEM | IORESOURCE_BUSY.
This will prevent anything else from accidentally mapping over it.
