(screen resolution and refresh rate) The property is an array of a custom type to make the syntax slightly less awkward to use, for example: -device '{"driver":"apple-gfx-pci", "display-modes":["1920x1080@60", "3840x= 2160@60"]}' Signed-off-by: Phil Dennis-Jordan --- v4: * Switched to the native array property type, which recently gained command line support. * The property has also been added to the -mmio variant. * Tidied up the code a little. v5: * Better error handling and buffer management in property parsing and output. v6: * Switched to using NSMutableArray for the mode list to avoid need for allocating a temporary array - previously done with alloca. hw/display/apple-gfx-mmio.m | 8 +++ hw/display/apple-gfx-pci.m | 9 ++- hw/display/apple-gfx.h | 12 ++++ hw/display/apple-gfx.m | 137 +++++++++++++++++++++++++++++++----- hw/display/trace-events | 2 + 5 files changed, 148 insertions(+), 20 deletions(-) diff --git a/hw/display/apple-gfx-mmio.m b/hw/display/apple-gfx-mmio.m index 66d81d38326..ddc8a2fc4f3 100644 --- a/hw/display/apple-gfx-mmio.m +++ b/hw/display/apple-gfx-mmio.m @@ -258,6 +258,12 @@ static void apple_gfx_mmio_reset(Object *obj, ResetTyp= e type) [s->common.pgdev reset];
