Android q: failed to import prime fd
Replace the hwcomposer.drm.so to hwcomposer.xx.so. The android q system can not work.dumpsys SurfaceFlinger have the only plane bootanimation. The logcat has:

int DrmGenericImporter::ImportBuffer(buffer_handle_t handle, hwc_drm_bo_t *bo) {
105 gralloc_handle_t *gr_handle = gralloc_handle(handle);
106 if (!gr_handle)
107 return -EINVAL;
108
109 uint32_t gem_handle;
110 int ret = drmPrimeFDToHandle(drm_->fd(), gr_handle->prime_fd, &gem_handle);
111 if (ret) {
112 ALOGE("failed to import prime fd %d ret=%d", gr_handle->prime_fd, ret);
113 return ret;
114 }I confuse that
gralloc_handle_t *gr_handle = gralloc_handle(handle);
how can buffer_handle_t translate to gralloc_handle_t. where the prime fd come from.
struct gralloc_handle_t {
37 native_handle_t base;
38
39 /* dma-buf file descriptor
40 * Must be located first since, native_handle_t is allocated
41 * using native_handle_create(), which allocates space for
42 * sizeof(native_handle_t) + sizeof(int) * (numFds + numInts)
43 * numFds = GRALLOC_HANDLE_NUM_FDS
44 * numInts = GRALLOC_HANDLE_NUM_INTS
45 * Where numFds represents the number of FDs and
46 * numInts represents the space needed for the
47 * remainder of this struct.
48 * And the FDs are expected to be found first following
49 * native_handle_t.
