Paging and Interrupt make crash

Post by maxmati »

I've initialize Paging by this code:

Code: Select all

unsigned long *page_directory = (unsigned long *) 0x720000;
unsigned long *page_table = (unsigned long *) 0x721000; // the page table comes right after the page directory


void init_paging()
{
    unsigned long address=0; // holds the physical address of where a page is

    // map the first 4MB of memory
    for (unsigned int i=0; i<2048; i++)
    {
        page_table[i] = address | 3; // attribute set to: supervisor level, read/write, present(011 in binary)
        address = address + 4096; // 4096 = 4kb
    }
    
#ifdef DEBUG
    kprint(address,WHITE_TXT,20,0);
    kprint(sizeof(unsigned long),WHITE_TXT,21,0);
#endif//DEBUG


    // fill the first entry of the page directory
    page_directory[0] = (unsigned long) page_table; // attribute set to: supervisor level, read/write, present(011 in binary)
    page_directory[0] = (unsigned long) page_directory[0] | 3;
    page_directory[1] = (unsigned long) page_table+1024; // attribute set to: supervisor level, read/write, present(011 in binary)
    page_directory[1] = (unsigned long) page_directory[1] | 3;
    
#ifdef DEBUG
    kprint((unsigned int) page_table,WHITE_TXT,22,0);
    kprint((unsigned int) (page_table+1024) ,WHITE_TXT,23,0);
#endif//DEBUG
    
    for(unsigned int i=1; i<1024; i++)
    {
	page_directory[i] = 0 | 2; // attribute set to: supervisor level, read/write, not present(010 in binary)
    };
    
    // write_cr3, read_cr3, write_cr0, and read_cr0 all come from the assembly functions
    write_cr3((unsigned long) page_directory); // put that page directory address into CR3
    write_cr0(read_cr0() | 0x80000000); // set the paging bit in CR0 to 1
}
and make any interrupt i've got crash.
I know that you need some more data but i don't know whats data so write if you need something else.

Have you tried looking at the standard responses? You could have known what we were likely to ask next: bochs and logs.


On another note: 2048 is not the number of entries in a page table.

To be fair to him he does set up two page tables with that loop (depsite the comment above it to the contrary) then insert them correctly into the page directory further down. His error though is the loop 'for(unsigned int i=1; i<1024; i++)' which overwrites the 2nd PD entry he has set up (hence the page fault with CR2 = 0x710041) . Hint to OP: 'for(unsigned int i = 2...'. One thing to note when reading the bochs log is not to look at the last register dump as when it enconunters a triple fault it will output first the register dump at the site of the problem, then reset itself and then when you close it it will dump the registers again - so you need to look further up for the line 'exception(): 3rd (14) exception with no resolution, shutdown status is 00h, resetting'

John.

00141683685e[CPU0 ] interrupt(): not accessible or not code segment cs=0x0008
This begs for "Do you know how to read?" as the answer.

You might want to get/build a copy of Bochs with debugger, from within there you can diagnose what the CPU sees from your key structures and if they actually correspond to what you think they should.
