I'm adding suspend/resume support to echoaudio drivers. I was
reading /Documentation/power/pci.txt:
"
pci_set_power_state(PCI_D0);
pci_restore_state();
/* device's irq possibly is changed, driver should take care */
"
The card does not support D[0-3] states. The driver suspends the card by
turning the DSP off, without changing the PCI state. Can IRQ, memory mapped
regions, whatever, change on resume ?
Are pci_save_state() and pci_enable_wake() useful/required in this case ?
