[libvirt] [PULL v2 27/43] memory-device: drop get_region_size()

From: David Hildenbrand <david(a)redhat.com&gt; There are no remaining users of get_region_size() except memory_device_get_region_size() itself. We can make memory_device_get_region_size() work directly on get_memory_region() instead and drop get_region_size(). In addition, we can now use memory_device_get_region_size() in pc-dimm code to implement get_plugged_size()" Reviewed-by: David Gibson <david(a)gibson.dropbear.id.au&gt; Reviewed-by: Igor Mammedov <imammedo(a)redhat.com&gt; Signed-off-by: David Hildenbrand <david(a)redhat.com&gt; Message-Id: <20181005092024.14344-12-david(a)redhat.com&gt; Signed-off-by: Eduardo Habkost <ehabkost(a)redhat.com&gt; --- include/hw/mem/memory-device.h | 1 - hw/mem/memory-device.c | 11 +++++++++-- hw/mem/pc-dimm.c | 18 +----------------- 3 files changed, 10 insertions(+), 20 deletions(-) diff --git a/include/hw/mem/memory-device.h b/include/hw/mem/memory-device.h index 659f38385c..9c3398bc4a 100644 --- a/include/hw/mem/memory-device.h +++ b/include/hw/mem/memory-device.h @@ -71,7 +71,6 @@ typedef struct MemoryDeviceClass { * most devices, this corresponds to the size of the memory region. */ uint64_t (*get_plugged_size)(const MemoryDeviceState *md, Error **errp); - uint64_t (*get_region_size)(const MemoryDeviceState *md, Error **errp); /* * Return the memory region of the memory device. diff --git a/hw/mem/memory-device.c b/hw/mem/memory-device.c index 425830c65c..07749bab69 100644 --- a/hw/mem/memory-device.c +++ b/hw/mem/memory-device.c @@ -268,9 +268,16 @@ void memory_device_unplug_region(MachineState *ms, MemoryRegion *mr) uint64_t memory_device_get_region_size(const MemoryDeviceState *md, Error **errp) { - MemoryDeviceClass *mdc = MEMORY_DEVICE_GET_CLASS(md); + const MemoryDeviceClass *mdc = MEMORY_DEVICE_GET_CLASS(md); + MemoryRegion *mr; - return mdc->get_region_size(md, errp); + /* dropping const here is fine as we don't touch the memory region */ + mr = mdc->get_memory_region((MemoryDeviceState *)md, errp); + if (!mr) { + return 0; + } + + return memory_region_size(mr); } static const TypeInfo memory_device_info = { diff --git a/hw/mem/pc-dimm.c b/hw/mem/pc-dimm.c index c9f6ad589e..47b2e83389 100644 --- a/hw/mem/pc-dimm.c +++ b/hw/mem/pc-dimm.c @@ -236,21 +236,6 @@ static uint64_t pc_dimm_md_get_addr(const MemoryDeviceState *md) return dimm->addr; } -static uint64_t pc_dimm_md_get_region_size(const MemoryDeviceState *md, - Error **errp) -{ - MemoryDeviceClass *mdc = MEMORY_DEVICE_GET_CLASS(md); - MemoryRegion *mr; - - /* dropping const here is fine as we don't touch the memory region */ - mr = mdc->get_memory_region((MemoryDeviceState *)md, errp); - if (!mr) { - return 0; - } - - return memory_region_size(mr); -} - static MemoryRegion *pc_dimm_md_get_memory_region(MemoryDeviceState *md, Error **errp) { @@ -302,8 +287,7 @@ static void pc_dimm_class_init(ObjectClass *oc, void *data) mdc->get_addr = pc_dimm_md_get_addr; /* for a dimm plugged_size == region_size */ - mdc->get_plugged_size = pc_dimm_md_get_region_size; - mdc->get_region_size = pc_dimm_md_get_region_size; + mdc->get_plugged_size = memory_device_get_region_size; mdc->get_memory_region = pc_dimm_md_get_memory_region; mdc->fill_device_info = pc_dimm_md_fill_device_info; } -- 2.18.0.rc1.1.g3f1ff2140
