pci: pci-uclass: Add VF BAR map support for Enhanced Allocation

2020-08-25T06:01:16Z

Makes dm_pci_map_bar API available to map BAR for Virtual function PCI devices which support Enhanced Allocation. Signed-off-by: Suneel Garapati Cc: Simon Glass Cc: Bin Meng

pci: pci-uclass: Add support for Single-Root I/O Virtualization

2020-08-25T06:01:16Z

SR-IOV - Single Root I/O Virtualization PF - Physical Function VF - Virtual Function If SR-IOV capability is present, use it to initialize Virtual Function PCI device instances. pci_sriov_init function will read SR-IOV registers to create VF devices under the PF PCI device and also bind driver if available. This function needs to be invoked from Physical function device driver which expects VF device support, creating minimal impact on existing framework.

pci: pci-uclass: Dynamically allocate the PCI regions

2020-08-25T03:41:09Z

Instead of using a fixed length pre-allocated array of regions, this patch moves to dynamically allocating the regions based on the number of available regions plus the necessary regions for DRAM banks. Since MAX_PCI_REGIONS is not needed any more, its removed completely with this patch. Signed-off-by: Stefan Roese Reviewed-by: Simon Glass Cc: Bin Meng Cc: Thierry Reding Cc: Marek Vasut

pci: Move some PCIe register offset definitions to a common header

2020-07-09T13:46:12Z

Some PCI Express register offsets are currently defined in multiple drivers, move them to a common header to avoid re-definitions and as a pre-requisite for adding new PCIe driver. While at it replace some spaces with tabs. Signed-off-by: Sylwester Nawrocki Reviewed-by: Bin Meng Reviewed-by: Nicolas Saenz Julienne Signed-off-by: Matthias Brugger

pci: Add a macro to convert BDF from linux to U-Boot

2020-04-24T20:40:09Z

U-Boot's BDF format has its bits in the same position as the device tree PCI definition. Some x86 devices use linux format in their register format and it is useful to be able to convert to U-Boot format. Add a macro for this. Signed-off-by: Simon Glass

pci: definition of pci_addr_t and pci_size_t

2020-02-13T15:10:50Z

Currently the size of pci_addr_t and pci_size_t depends on CONFIG_SYS_PCI_64BIT. For qemu_arm64_defconfig with 4 GiB RAM this leads to an error pci_hose_phys_to_bus: invalid physical address which is due to the truncation of the bus address in _dm_pci_phys_to_bus. Defining CONFIG_SYS_PCI_64BIT is not a solution as this results in an error PCI: Failed autoconfig bar 10 So let's use unsigned long for pci_addr_t and pci_size_t if CONFIG_SYS_PCI_64BIT is not defined. Considering that 32bit U-Boot is used to launch some 64bit x86 systems we cannot do without CONFIG_SYS_PCI_64BIT requiring u64 as type. Signed-off-by: Heinrich Schuchardt Reviewed-by: Simon Glass
