Hi all, I am working on grub-1.97.1. I wanted to know if there is any mechanism in grub2 that maps virtual addresses to physical addresses below 1 MB?
When I checked the code for grub-0.97, I found that there are function as below
#define phys_to_virt(x) (x)
#define virt_to_phys(x) (x)
Are there any similar functions in grub-1.97.1?
Also, when I allocated memory using grub_malloc() and printed the address returned from the function it was (0x7da6d810). This seems to be a 32-bit address. I wanted to know whether I can allocate some memory in the region below 1MB?
Regards,
Kiran Pawar.
