[PATCH 0/9] efi: add PCI controller driver

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This series adds support for reusing existing barebox PCI drivers under
EFI. This means implementation of the EFI_PCI_ROOT_BRIDGE_IO_PROTOCOL_GUID,
instead of EFI_PCI_IO_PROTOCOL_GUID, which abstracts the devices and
handles enumeration.

This was tested with the default QEMU x86_64 machine and OVMF (Tianocore)
as UEFI firmware and an emulated 8250_pci (driver included in this
series):

qemu-system-x86_64 -pflash OVMF.fd -device pci-serial,chardev=cdev0 \
	-chardev file,id=cdev0,path=COM -nographic /dev/sdb

Driver is written against UEFI Specification 2.1D. This is my first
dabble with PCI controllers, so please take a more thorough look.

Thanks!
Ahmad

  efi: add and use new efi_device_has_guid helper
  driver: add missing parentheses around macro argument
  efi: fix off-by-one in mem_malloc_init(..., end)
  x86: efi: lds: don't discard any relocation sections
  PCI: add driver_data member to struct pci_device_id
  PCI: copy over some Linux PCI helpers
  efi: turn set of defines into enumerations
  pci: add EFI PCI root bridge IO protocol driver
  serial: add support for PCI NS16550 UARTs
