Subject: [PATCH v18 0/2] Add quirk for PCIe root port on AMD systems
Date: Tue, 12 Sep 2023 23:08:30 -0500 [thread overview]
Message-ID: <20230913040832.114610-1-mario.limonciello@amd.com> (raw)
Iain reports that USB devices can't be used to wake a Lenovo Z13
from suspend. This is because the PCIe root port has been put
into D3hot and AMD's platform can't handle USB devices waking the
platform from a hardware sleep state in this case.
The firmware doesn't express this limitation in a way that Linux
recognizes so this series introduces a quirk for this problem.
Previous submissions:
* v17
https://lore.kernel.org/platform-driver-x86/20230906184354.45846-1-mario.limonciello@amd.com/
This version implemented constraints for the amd-pmc driver and introduced
a veto/optin system for the PCI core as suggested by Hans.
Rafael suggested not to use the veto/optin system and instead use a quirk.
* v16
https://lore.kernel.org/platform-driver-x86/20230829171212.156688-1-mario.limonciello@amd.com/
This version implemented constraints for the amd-pmc driver.
* v15
https://lore.kernel.org/platform-driver-x86/20230828042819.47013-1-mario.limonciello@amd.com/#t
This version hardcoded the quirk into amd-pmc driver as part of suspend
callback.
* v14
https://lore.kernel.org/linux-pci/20230818193932.27187-1-mario.limonciello@amd.com/
https://lore.kernel.org/linux-pci/20230818194007.27410-1-mario.limonciello@amd.com/
https://lore.kernel.org/linux-pci/20230818194027.27559-1-mario.limonciello@amd.com/
This version implemented constraints exporting and limited the policy for
>= 2015 to Intel only. It also added support for constraints optin.
V13 was split into multiple parts to make it easier to land. 14.b was
merged.
