Subject: [PATCH v4 00/10] PCI: endpoint: Differentiate between disabled and reserved BARs
Date: Thu, 12 Mar 2026 14:02:28 +0100 [thread overview]
Message-ID: <20260312130229.2282001-12-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 this series and will send a small series on top of
this one.
Changes since v3:
-Modified patch 1 to simply drop BAR_RESERVED for a BAR following an
only_64bit BAR (Manivannan).
-Added a patch from Manikanta, to make his follow-up series smaller,
since this series touches the same lines anyway.
Link to v3:
https://lore.kernel.org/linux-pci/20260302095913.48155-11-cassel@kernel.org/
Koichiro Den (2):
PCI: endpoint: Describe reserved subregions within BARs
PCI: dw-rockchip: Describe RK3588 BAR4 DMA ctrl window
Manikanta Maddireddy (1):
PCI: endpoint: Allow only_64bit on BAR_RESERVED
Niklas Cassel (7):
PCI: endpoint: Do not mark the BAR succeeding a 64-bit BAR as
BAR_RESERVED
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
