I'm facing some troubles with PCIe TLP re-ordering. Our device doesn't actually support TLP relaxed oerering even announcing the support in its configuration.
I've tried to disabled it through a call to BUS_INTERFACE_STANDARD::SetBusData() and even this was correctly set in the PCI_EXPRESS_CAPABILITY, this was not effective. It looks that the capabilities are only for information (read access).
Then I've tried to disable this feature at the chipset/BIOS level. But, until now I've found nothing to do this (PCI.SYS, Registry).
So, is it possible to disable it ?
Context : Windows 10-21H2, kernel mode driver.
Thanks in advance,
