Subject: [PATCH v3 0/4] PCI/ACPI: Simplify PCIe _OSC feature negotiation
Date: Tue, 24 Aug 2021 14:20:50 +0200	[thread overview]
Message-ID: <20210824122054.29481-1-joro@8bytes.org> (raw)

From: Joerg Roedel <jroedel@suse.de>

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
