No, it actually does violate the spec. Feel free to read it yourself.
We are not supposed to do Native PCIe without first successfully executing
OSC. Period. If you do, you are violating the spec.
To be fair, we have violated the spec before in order to get crappy
hardware or to work around crappy ACPI implementations.
acpi_sleep=s3_bios for example violates the spec, but yet it is the
only way to get certain laptops to suspend/resume correctly.
The question to ask is whether violating the spec will lead to (a) a
potential system hang/crash, (b) data corruption, (c) physical harm to
the device/laptop.
And the answer is most definitely yes to at least a) and c) on specific
hardware I know about.
I'm hearing a lot of FUD here, with no details.
Please, tell us more..
Thanks.
