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. |
