Accessing 64-bit BARs

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello all,

For accessing memory-mapped 64bit-BAR regions of a PCI card, the
respective BAR regions has to be made accessible to the kernel using
ioremap() function.
Then readl()/writel() are working fine on the address returned by ioremap().
This is working in linux-2.6.9.

Now when i tried the latest kernel i.e. linux-2.6.22-8, things were not working.
Is there any change in the way of accessing 64-bit BAR?
OR
i am missing any step ?

Any link/help will be appreciated.
