2019-08-16Include hw/hw.h exactly where neededMarkus Armbruster
In my "build everything" tree, changing hw/hw.h triggers a recompile of some 2600 out of 6600 objects (not counting tests and objects that don't depend on qemu/osdep.h). The previous commits have left only the declaration of hw_error() in hw/hw.h. This permits dropping most of its inclusions. Touching it now recompiles less than 200 objects.

2019-05-20pcie: Remove redundant test in pcie_mmcfg_data_{read,write}()David Gibson
These functions have an explicit test for accesses above the device's config size. But pci_host_config_{read,write}_common() which they're about to call already have checks against the config space limit and do the right thing. So, remove the redundant tests.

2017-10-15PCI: PCIe access should always be little endianMatt Redfearn
PCIe busses are always little endian, so set the endianness of the memory region to little endian rather than native such that operations work as expected on big endian targets.

2015-02-16pcie: remove mmconfig memory leak and wrap mmconfig update with transactionPaolo Bonzini
This memory leak was introduced inadvertently by omitting object_unparent. A better fix is to use the new memory_region_set_size instead of destroying and recreating the MMIO region on the fly. Also, ensure that unmapping and remapping the region is done atomically. Acked-by: Michael S. Tsirkin <mst@redhat.com> Reviewed-by: Michael S.

2015-01-26pci: Split pcie_host_mmcfg_map()Alexander Graf
The mmcfg space is a memory region that allows access to PCI config space in the PCIe world. To maintain abstraction layers, I would like to expose the mmcfg space as a sysbus mmio region rather than have it mapped straight into the system's memory address space though. So this patch splits the initialization of the mmcfg space from the actual mapping, allowing us to only have an mmfg memory region without the map.
