RE: log in prompt out of screen
Thanks Mark for your reply. I will try to get the info. Yet the unit is now on a remote site so may take a while. Will come back once I have it.

log in prompt out of screen
Hello experts, I have currently installed SL6.4 on a machine with PCM-3362 PC104 Atom processor. Everything works apart from the login screen cannot be seen each time after booting to the splash. It seems like the log in prompt is out of the screen. The mouse cursor is there. After a while, I can move the cursor and hit the return key then I can see the log in prompt. I have tried all combination after googling on the web with the resolution, frequency settings etc with no luck. The machine can be used but very awkward each time I have to hit the return key to get the log in screen. Has anybody seen the same symptom? How can I fix it please? Many thanks, Jim
remap_page_range in SL kernel 2.6.9-5.0.5.EL-i686
Does anybody know the prototype and its arguments of remap_page_range
function in kernel 2.6.9-5.0.5.EL-i686 please? It looks like the
remap_pfn_range function doesn't exist in the version. I try to map the pci
device memory to the user space in the device driver but have no luck so
far.
The code is pretty simple in the driver.
static int my_mmap(struct file *filp, struct vm_area_struct *vma)
{
if (remap_page_range(vma, vma->vm_start, vm->vm_pgoff,
vma->vm_end - vma->vm_start,
vma->vm_page_prot))
return -EAGAIN;
return 0;
}
And the user space call looks like this:
char* data;
int fd = open("/dev/my_dev", O_RDWR);
data = mmap(0, 0x1000, PROT_READ | PROT_WRITE, MAP_SHARED, fd,
0xE2E0);
It always returns me the same data= 0x9c3de3 and accessing it gets nothing
meaningful.
Any ideas?
Best regards,
Jim Chen
