Write-combining


Is there an easy way to check weather PCI Write-Combining is enabled or not? I'm performing some measurements and from the numbers I got I've concluded that it can only be enabled. But I would like to be sure about it. Has anyone ever written a software that checks the PCI page flags? Does linux provide support for that (something like a macro I could use)?


Thanks in advance.

You can use "lspci -vv". Then to set it using setpci. Its very dangerous, if you do not know what you are doing.

Yep, I'm sure "lspci -vv" will give deep information about pci devices and their settings.

Another way is look into the /proc directory.

Did you try it?
