Subject: [PATCH v5 00/12] PCI endpoint 64-bit BAR fixes
Date:   Wed, 28 Mar 2018 13:50:05 +0200

PCI endpoint fixes to improve the way 64-bit BARs are handled.


There are still future improvements that could be made:

pci-epf-test.c always allocates space for
6 BARs, even when using 64-bit BARs (which
really only requires us to allocate 3 BARs).

pcitest.sh will print "NOT OKAY" for BAR1,
BAR3, and BAR5 when using 64-bit BARs.
This could probably be improved to say
something like "N/A (64-bit BAR)".

Niklas Cassel (12):
  PCI: endpoint: BAR width should not depend on sizeof dma_addr_t
  PCI: endpoint: Simplify epc->ops->set_bar()/pci_epc_set_bar()
  PCI: endpoint: Setting BAR_5 to 64-bits wide is invalid
  PCI: endpoint: Setting 64-bit/prefetch bit is invalid when IO is set
  PCI: endpoint: Setting a BAR size > 4 GB is invalid if 64-bit flag is
    not set
  PCI: designware-ep: Make dw_pcie_ep_set_bar() handle 64-bit BARs
    properly
  PCI: cadence: Set PCI_BASE_ADDRESS_MEM_TYPE_64 if a 64-bit BAR was
    set-up
  PCI: endpoint: Handle 64-bit BARs properly
  PCI: endpoint: Make epc->ops->clear_bar()/pci_epc_clear_bar() take
    struct *epf_bar
  PCI: endpoint: Make sure that BAR_5 does not have 64-bit flag set when
    clearing
  PCI: designware-ep: Make dw_pcie_ep_reset_bar() handle 64-bit BARs
    properly
  misc: pci_endpoint_test: Handle 64-bit BARs properly
