From 8bccc5b80678c69f7729ce4cd232c0aa98fa6277 Mon Sep 17 00:00:00 2001 From: Yishai Hadas Date: Tue, 19 Dec 2023 11:32:45 +0200 Subject: vfio/pci: Expose vfio_pci_core_setup_barmap() Expose vfio_pci_core_setup_barmap() to be used by drivers. This will let drivers to mmap a BAR and re-use it from both vfio and the driver when it's applicable. This API will be used in the next patches by the vfio/virtio coming driver.
