Hi all,
I was wondering if it is possible to memory map buffer that has _not_
dynamically been allocated (e.g. via kmalloc or vmalloc) into user space?
Example:
Within my device driver code I have the following table ...
typedef struct foobar_entry {
char foo[1024];
char bar[1024];
uint32_t x;
uint32_t y;
} foobar_entry_t;
foobar_entry_t foobar_table[] =
{
{ "foo1", "bar1", 232, 0 },
{ "foo2", "bar2", 233, 1 },
{ "foo3", "bar3", 234, 0 },
{ "foo4", "bar4", 235, 1 },
};
EXPORT_SYMBOL(foobar_table);
... and I'd like this to be memory mappped as read-only into user space.
I tried things with 'remap_pfn_range', but without success. Do you have
any idea/code example how to manage this?
Best regards,
Daniel
