Subject: [PATCH v3 0/9] PCI: endpoint: Differentiate between disabled and reserved BARs
Date: Mon, 2 Mar 2026 10:59:12 +0100 [thread overview]
Message-ID: <20260302095913.48155-11-cassel@kernel.org> (raw)
Hello all,
This series was originally written in response to the patch series from
Manikanta Maddireddy that was posted here:
https://lore.kernel.org/linux-pci/291dab65-3fa6-4fc8-90a2-4ad608ca015c@nvidia.com/T/#t
Manikanta has reviewed V1 and will send a small series on top of this one.
Changes since v2:
-Picked up tags from Frank and Koichiro (thank you)
-Fixed a comment in pcie-dw-rockchip.c to no longer reflect the old
definition of BAR_RESERVED.
Link to v2:
https://lore.kernel.org/linux-pci/20260225170324.4033466-11-cassel@kernel.org/
Koichiro Den (2):
PCI: endpoint: Describe reserved subregions within BARs
PCI: dw-rockchip: Describe RK3588 BAR4 DMA ctrl window
Niklas Cassel (7):
PCI: endpoint: Introduce pci_epc_bar_type BAR_64BIT_UPPER
PCI: endpoint: Introduce pci_epc_bar_type BAR_DISABLED
PCI: dwc: Replace certain BAR_RESERVED with BAR_DISABLED in glue
drivers
PCI: dwc: Disable BARs in common code instead of in each glue driver
PCI: endpoint: pci-epf-test: Advertise reserved BARs
misc: pci_endpoint_test: Give reserved BARs a distinct error code
selftests: pci_endpoint: Skip reserved BARs
