Hi This is a cleanup series to change functions in hw/vfio/ to return bool when the error is passed through errp parameter, also some cleanup with g_autofree.
See discussion at https://lists.gnu.org/archive/html/qemu-devel/2024-04/msg04782.html This series processed below files: hw/vfio/container.c hw/vfio/iommufd.c hw/vfio/cpr.c backends/iommufd.c So above files are clean now, there are still other files need processing in hw/vfio. Test done on x86 platform: vfio device hotplug/unplug with different backend reboot Thanks Zhenzhong Changelog: v2: - split out g_autofree code as a patch (Cédric) - add processing for more files Zhenzhong Duan (11): vfio/pci: Use g_autofree in vfio_realize vfio/pci: Use g_autofree in iommufd_cdev_get_info_iova_range() vfio: Make VFIOIOMMUClass::attach_device() and its wrapper return bool vfio: Make VFIOIOMMUClass::setup() return bool vfio: Make VFIOIOMMUClass::add_window() and its wrapper return bool vfio/container: Make vfio_connect_container() return bool vfio/container: Make vfio_set_iommu() return bool vfio/container: Make vfio_get_device() return bool vfio/iommufd: Make iommufd_cdev_*() return bool vfio/cpr: Make vfio_cpr_register_container() return bool backends/iommufd: Make iommufd_backend_*() return bool include/hw/vfio/vfio-common.h | 6 +- include/hw/vfio/vfio-container-base.h | 18 ++--- include/sysemu/iommufd.h | 6 +- backends/iommufd.c | 29 +++---- hw/vfio/ap.c | 6 +- hw/vfio/ccw.c | 6 +- hw/vfio/common.c | 6 +- hw/vfio/container-base.c | 8 +- hw/vfio/container.c | 81 +++++++++---------- hw/vfio/cpr.c | 4 +- hw/vfio/iommufd.c | 109 +++++++++++--------------- hw/vfio/pci.c | 12 ++- hw/vfio/platform.c | 7 +- hw/vfio/spapr.c | 28 +++---- backends/trace-events | 4 +- 15 files changed, 147 insertions(+), 183 deletions(-) -- 2.34.1
