Hi, This series add support for guests writting to PCI BARs. Edk2 does this and is not aware of the "linux,pci-probe-only" property in the chosen node. - Patches 1 to 3 do miscelaneous fixes - Patch 4 fixes the way we deal with BAR sizing - Patches 5 to 8 fixes the allocation/assignment of PCI IO BARs - Patches 9 to 12 make it possible to remap ioport and mmio regions from vcpu threads, without pausing the entire VM - Patches 13 to 16 adds the support for writting to BARs Cheers, Julien --> Julien Thierry (15): Makefile: Only compile vesa for archs that need it brlock: Always pass argument to br_read_lock/unlock brlock: fix build with KVM_BRLOCK_DEBUG ioport: pci: Move port allocations to PCI devices pci: Fix ioport allocation size arm/pci: Fix PCI IO region arm/pci: Do not use first PCI IO space bytes for devices brlock: Use rwlock instead of pause ref_cnt: Add simple ref counting API mmio: Allow mmio callbacks to be called without locking ioport: Allow ioport callbacks to be called without locking vfio: Add support for BAR configuration virtio/pci: Make memory and IO BARs independent virtio/pci: update virtio mapping when PCI BARs are reconfigured arm/fdt: Remove PCI probe only property Sami Mujawar (1): pci: Fix BAR resource sizing arbitration Makefile | 3 +- arm/fdt.c | 1 - arm/include/arm-common/pci.h | 1 + arm/kvm.c | 3 + arm/pci.c | 24 ++++- hw/pci-shmem.c | 3 +- hw/vesa.c | 4 +- include/kvm/brlock.h | 21 +--- include/kvm/ioport.h | 5 - include/kvm/kvm.h | 2 + include/kvm/pci.h | 2 + include/kvm/ref_cnt.h | 53 ++++++++++ include/kvm/virtio-pci.h | 1 + ioport.c | 80 ++++++++-------- kvm.c | 4 + mmio.c | 30 ++++-- pci.c | 59 +++++++++++- vfio/core.c | 6 +- vfio/pci.c | 82 +++++++++++++++- virtio/pci.c | 223 ++++++++++++++++++++++++++++++++++++------- 20 files changed, 491 insertions(+), 116 deletions(-) create mode 100644 include/kvm/ref_cnt.h -- 1.9.1
