Hi all, I want to send the data to kernel space and wait till the interrupt finishes.(PCI dma transfer)
I could do it using a shared variable between user and kernel spaces. Then polling is done in the user space checking the shared variable. But this is not an effective way. I want to use wait/wakeup method for this. ( wait in the user space and wake up the user space process in the interrupt routine). It is possible to sychronize the kernel/user spaces in this way? Can anyone help me with this? Thanx in advance. Sumudu
