Subject: [Nouveau] [PATCH v2 0/9] Improvements to pcie_bandwidth_available() for eGPUs
Date: Fri, 3 Nov 2023 14:07:49 -0500 [thread overview]
Message-ID: <20231103190758.82911-1-mario.limonciello@amd.com> (raw)
Downstream drivers are getting the wrong values from
pcie_bandwidth_available() which is causing problems for performance
of eGPUs.
This series overhauls Thunderbolt related device detection and uses
the changes to change the behavior of pcie_bandwidth_available().
NOTE: This series is currently based on top of v6.6 + this change that
will be merged for 6.7:
Link: https://patchwork.freedesktop.org/patch/564738/
v1->v2:
* Rename is_thunderbolt
* Look for _DSD instead of link
* Drop pci_is_thunderbolt_attached() from all drivers
* Adjust links
* Adjust commit messages
* Add quirk for Tiger Lake
Mario Limonciello (9):
drm/nouveau: Switch from pci_is_thunderbolt_attached() to
dev_is_removable()
drm/radeon: Switch from pci_is_thunderbolt_attached() to
dev_is_removable()
PCI: Drop pci_is_thunderbolt_attached()
PCI: Move the `PCI_CLASS_SERIAL_USB_USB4` definition to common header
PCI: pciehp: Move check for is_thunderbolt into a quirk
PCI: Rename is_thunderbolt to is_tunneled
PCI: ACPI: Detect PCIe root ports that are used for tunneling
PCI: Exclude PCIe ports used for tunneling in
pcie_bandwidth_available()
PCI: Add a quirk to mark 0x8086 : 0x9a23 as supporting PCIe tunneling
