Subject: [PATCH v5 0/7] Fix PF/VF dependency issue
Date: Thu, 1 Aug 2019 17:05:57 -0700 [thread overview]
Message-ID: <cover.1564702313.git.sathyanarayanan.kuppuswamy@linux.intel.com> (raw)
From: Kuppuswamy Sathyanarayanan <sathyanarayanan.kuppuswamy@linux.intel.com>
Current implementation of ATS, PASID, PRI does not handle VF dependencies
correctly. Following patches addresses this issue.
Changes since v4:
* Defined empty functions for pci_pri_init() and pci_pasid_init() for cases
where CONFIG_PCI_PRI and CONFIG_PCI_PASID are not enabled.
Changes since v3:
* Fixed critical path (lock context) in pci_restore_*_state functions.
Changes since v2:
* Added locking mechanism to synchronize accessing PF registers in VF.
* Removed spec compliance checks in patches.
* Addressed comments from Bjorn Helgaas.
Changes since v1:
* Added more details about the patches in commit log.
* Removed bulk spec check patch.
* Addressed comments from Bjorn Helgaas.
