hello,
Thanks rolf & roland.
pci_iomap() is not doing something extra. only it is some kind of
abstraction for IO-mapped OR memory mapped.
I know that my BARs are MMIO, so using ioremap() & readl()/writel()
combination should be fine.
But for the problem as explained in my first mail, any
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() can be used on the address
returned by ioremap().
I am doing the similar steps to access the BARs of a card.

Hi all,
I am running a user application which will just open/close my driver
(simple one, empty functions with only printks) infinitely.
A massive use of printk can slow down the system noticeably OR it can
affect some time calculations.
Apart from this, it was increasing top mem usage also.
