Hi,

It looks like discontiguous memory support is not available in 2.6.17 for Jornada 690 architecture. Code such as following (include/asm-sh/page.h from 2.6.11) has disappeared:

#ifdef CONFIG_DISCONTIGMEM
/* Just for HP690, for now.. */
#define __MEMORY_START_2ND (__MEMORY_START+0x02000000)
#define __MEMORY_SIZE_2ND 0x001000000 /* 16MB */
#endif

Any idea? solution?

Thx by advance
regards

Pierre

We are using a ghost area where the memory on 690 looks linear, adding support for non-linear isnt a problem.

Hum, could you explain? I'm not very familiar with the subject, what do you mean with "is not a problem ?" what's the way to use such a beast?

Thx by advance

Well, the usual way is to set a virtal memory range and then map all physical areas there so it appears linear while its physically not. You can look at various arm handheld platforms for examples.

Think of the virtual memory as only a pointer to the real adress.

Of course its abit more complicated but you should get the idea.

Could you give me your email? kristoffer@jlime.com does not work.
