This extended frame is properly splited and rendered on the corresponding scanout surfaces but not in case of blob-resource (zero copy). This code change lets the qemu split this one large surface data into multiple in case of blob-resource as well so that each sub frame then can be blitted properly to each scanout. v2: resizing qemu console in virtio_gpu_update_dmabuf to scanout's width and height Signed-off-by: Dongwon Kim --- hw/display/virtio-gpu-udmabuf.c | 21 ++++++++++++++------- hw/display/virtio-gpu.c | 4 ++-- include/hw/virtio/virtio-gpu.h | 5 +++-- include/ui/console.h | 4 ++++ stubs/virtio-gpu-udmabuf.c | 3 ++- 5 files changed, 25 insertions(+), 12 deletions(-) diff --git a/hw/display/virtio-gpu-udmabuf.c b/hw/display/virtio-gpu-udmabuf.c index 3c01a415e7..aadf1221ef 100644 --- a/hw/display/virtio-gpu-udmabuf.c +++ b/hw/display/virtio-gpu-udmabuf.c @@ -171,7 +171,8 @@ static VGPUDMABuf *virtio_gpu_create_dmabuf(VirtIOGPU *g, uint32_t scanout_id, struct virtio_gpu_simple_resource *res, - struct virtio_gpu_framebuffer *fb) + struct virtio_gpu_framebuffer *fb, + struct virtio_gpu_rect *r) { VGPUDMABuf *dmabuf; @@ -183,6 +184,10 @@ static VGPUDMABuf dmabuf->buf.width = fb->width; dmabuf->buf.height = fb->height; dmabuf->buf.stride = fb->stride; + dmabuf->buf.x = r->x; + dmabuf->buf.y = r->y; + dmabuf->buf.scanout_width = r->width; + dmabuf->buf.scanout_height = r->height; dmabuf->buf.fourcc = qemu_pixman_to_drm_format(fb->format); dmabuf->buf.fd = res->dmabuf_fd; @@ -195,24 +200,26 @@ static VGPUDMABuf int virtio_gpu_update_dmabuf(VirtIOGPU *g, uint32_t scanout_id, struct virtio_gpu_simple_resource *res, - struct virtio_gpu_framebuffer *fb) + struct virtio_gpu_framebuffer *fb, + struct virtio_gpu_rect *r) { struct virtio_gpu_scanout *scanout = &g->parent_obj.scanout[scanout_id]; VGPUDMABuf *new_primary, *old_primary = NULL; - new_primary = virtio_gpu_create_dmabuf(g, scanout_id, res, fb); + new_primary = virtio_gpu_create_dmabuf(g, scanout_id, res, fb, r); if (!new_primary) { return -EINVAL; } if (g->dmabuf.primary) { - old_primary = g->dmabuf.primary; + old_primary = g->dmabuf.primary[scanout_id]; } - g->dmabuf.primary = new_primary; + g->dmabuf.primary[scanout_id] = new_primary; + qemu_console_resize(scanout->con, - new_primary->buf.width, - new_primary->buf.height); + new_primary->buf.scanout_width, + new_primary->buf.scanout_height); dpy_gl_scanout_dmabuf(scanout->con, &new_primary->buf); if (old_primary) { diff --git a/hw/display/virtio-gpu.c b/hw/display/virtio-gpu.c index e183f4ecda..60db480719 100644 --- a/hw/display/virtio-gpu.c +++ b/hw/display/virtio-gpu.c @@ -523,9 +523,9 @@ static void virtio_gpu_resource_flush(VirtIOGPU *g, console_has_gl(scanout->con)) { dpy_gl_update(scanout->con, 0, 0, scanout->width, scanout->height); - return; } } + return; } if (!res->blob && @@ -633,7 +633,7 @@ static void virtio_gpu_do_set_scanout(VirtIOGPU *g, if (res->blob) { if (console_has_gl(scanout->con)) { - if (!virtio_gpu_update_dmabuf(g, scanout_id, res, fb)) { + if (!virtio_gpu_update_dmabuf(g, scanout_id, res, fb, r)) { virtio_gpu_update_scanout(g, scanout_id, res, r); return; } diff --git a/include/hw/virtio/virtio-gpu.h b/include/hw/virtio/virtio-gpu.h index bcf54d970f..6372f4bbb5 100644 --- a/include/hw/virtio/virtio-gpu.h +++ b/include/hw/virtio/virtio-gpu.h @@ -187,7 +187,7 @@ struct VirtIOGPU { struct { QTAILQ_HEAD(, VGPUDMABuf) bufs; - VGPUDMABuf *primary; + VGPUDMABuf *primary[VIRTIO_GPU_MAX_SCANOUTS]; } dmabuf; }; @@ -273,7 +273,8 @@ void virtio_gpu_fini_udmabuf(struct virtio_gpu_simple_resource *res); int virtio_gpu_update_dmabuf(VirtIOGPU *g, uint32_t scanout_id, struct virtio_gpu_simple_resource *res, - struct virtio_gpu_framebuffer *fb); + struct virtio_gpu_framebuffer *fb, + struct virtio_gpu_rect *r); /* virtio-gpu-3d.c */ void virtio_gpu_virgl_process_cmd(VirtIOGPU *g, diff --git a/include/ui/console.h b/include/ui/console.h index b30b63976a..87316aef83 100644 --- a/include/ui/console.h +++ b/include/ui/console.h @@ -167,6 +167,10 @@ typedef struct QemuDmaBuf { uint32_t fourcc; uint64_t modifier; uint32_t texture; + uint32_t x; + uint32_t y; + uint32_t scanout_width; + uint32_t scanout_height; bool y0_top; } QemuDmaBuf; diff --git a/stubs/virtio-gpu-udmabuf.c b/stubs/virtio-gpu-udmabuf.c index 81f661441a..f692e13510 100644 --- a/stubs/virtio-gpu-udmabuf.c +++ b/stubs/virtio-gpu-udmabuf.c @@ -20,7 +20,8 @@ void virtio_gpu_fini_udmabuf(struct virtio_gpu_simple_resource *res) int virtio_gpu_update_dmabuf(VirtIOGPU *g, uint32_t scanout_id, struct virtio_gpu_simple_resource *res, - struct virtio_gpu_framebuffer *fb) + struct virtio_gpu_framebuffer *fb, + struct virtio_gpu_rect *r) { /* nothing (stub) */ return 0;
