Subject: [patch 5/7] x86/pci: Select CONFIG_PCI_LOCKLESS_CONFIG
Date: Thu, 16 Mar 2017 22:50:07 +0100 [thread overview]
Message-ID: <20170316215057.295079391@linutronix.de> (raw)
In-Reply-To: 20170316215002.726697858@linutronix.de
[-- Attachment #1: x86-pci--Select-CONFIG_PCI_LOCKLESS_CONFIG.patch --]
[-- Type: text/plain, Size: 583 bytes --]
All x86 PCI configuration space accessors have either their own
serialization or can operate completely lockless (ECAM).
Disable the global lock in the generic PCI configuration space accessors.
