Why can't this can be a single device address space?

Is there any hardware limitations in PCI cause different address space? Please let me know. Thank you. Therefore you also can't access the configuration space to do whatever has to be done read IDs, set base address if you have a single device address space that includes the configuration space.

Also, at boot time it's unknow if the device will use IO mapped IO or memory mapped IO; so in which space should it be placed?

Also note that, although the configuration space is implemented on the PCI card, it's actually addressed based on slot. I think but I'm not sure it works slightly different from this, but it gives the basic idea. The following steps apply specifically to this IRP: Allocate a buffer from a paged pool and initialize it to zeros.

Initialize IoStatus. Deallocate the IRP and the buffer when they are no longer needed. Requirements Header Wdm. Yes No. Any additional feedback? Skip Submit.

Hi Mithlesh K. I need someone that is versed in nginx and reverse proxy config to troubleshoot a broken config that accepts web requests from a web app and forwards traffic to an API server. After an update on the origin server I am getting CORS errors so some mods are needed to the nginx proxy config.

Why do you want to do this? In Windows the kernel gives the driver the resource data, and reading the config space is rarely done. There is not much in the way of sample code to do this. Your initial question was on how to get the configuration data for one specific device, but rweverything.

The only way to do this is with a PCI Bus Filter, unfortunately bus filters are not well documented, and cannot be done with KMDF the preferred technology for drivers these days. I know of no sample bus drivers, that can be recommended. For debugging your device and understanding its config space, use windbg extension commands! This is an example of the hacks that should never be used in any commercial driver.
