Hi,
here is the third version of my patches to simplify the _OSC
negotiation of PCIe features between Linux and the firmware.
This version is a complete rewrite, so there is no changelog to the
previous version. Patches 1-3 are cleanups and small restructurings of
the code as a preparation for patch 4.
The last patch gets rid of the dedicated _OSC query to check for _OSC
support and merges that functionality into acpi_pci_osc_control_set().
This allows to simplify and/or remove other functions and consilidate
error handling in negotiate_os_control().
I have tested the patches with and without 'pcie_ports=compat' and
found no regressions on my test machine.
Please review.
Thanks,
Joerg
