From: Bjorn Helgaas Date: Thu, 23 Jan 2025 19:04:52 +0000 (-0600) Subject: Merge branch 'pci/endpoint' X-Git-Tag: v6.14-rc1~90^2~14 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=74855f6697e9ed4f0281a42ffd20eff5b2f75b2c;p=thirdparty%2Fkernel%2Flinux.git Merge branch 'pci/endpoint' - Destroy the EPC device in devm_pci_epc_destroy(), which previously didn't call devres_release() (Zijun Hu) - Simplify pci_epc_get() with class_find_device_by_name() (Zijun Hu) - Finish virtual EP removal in pci_epf_remove_vepf(), which previously caused a subsequent pci_epf_add_vepf() to fail with -EBUSY (Zijun Hu) - Write BAR_MASK before iATU registers in pci_epc_set_bar() so we don't depend on the BAR_MASK reset value being larger than the requested BAR size (Niklas Cassel) - Prevent changing BAR size/flags in pci_epc_set_bar() to prevent reads from bypassing the iATU if we reduced the BAR size (Niklas Cassel) - Verify address alignment when programming iATU so we don't attempt to write bits that are read-only because of the BAR size, which could lead to directing accesses to the wrong address (Niklas Cassel) - Implement artpec6 pci_epc_features so we can rely on all drivers supporting it so we can use it in EPC core code (Niklas Cassel) - Check for BARs of fixed size to prevent endpoint drivers from trying to change their size (Niklas Cassel) - Verify that requested BAR size is a power of two when endpoint driver sets the BAR (Niklas Cassel) * pci/endpoint: PCI: endpoint: Verify that requested BAR size is a power of two PCI: endpoint: Add size check for fixed size BARs in pci_epc_set_bar() PCI: artpec6: Implement dw_pcie_ep operation get_features PCI: dwc: ep: Add 'address' alignment to 'size' check in dw_pcie_prog_ep_inbound_atu() PCI: dwc: ep: Prevent changing BAR size/flags in pci_epc_set_bar() PCI: dwc: ep: Write BAR_MASK before iATU registers in pci_epc_set_bar() PCI: endpoint: Finish virtual EP removal in pci_epf_remove_vepf() PCI: endpoint: Simplify pci_epc_get() PCI: endpoint: Destroy the EPC device in devm_pci_epc_destroy() PCI: endpoint: Replace magic number '6' by PCI_STD_NUM_BARS --- 74855f6697e9ed4f0281a42ffd20eff5b2f75b2c
