你(们)好
我们已经检查 了 C66x、IVA-HD 等的存储器使用情况 当我在 remoteproc_core.c 中打印 iommu 时、它会打印2604MB。 它是否内存不足？
让您了解 linux-4.9.28+gitAUTOINC+e43d1050-geed43d1050\drivers\remoteproc\remoteproc_core.c 的 rproc_handle_devmem
静态 int rproc_handle_devmem (struct rproc * rproc、struct fw_RSC_devmem * RSC、
int 偏移、int 可用)

RET = iommu_map (rproc->domain、RSC->da、RSC->PA、RSC->len、RSC->flags)；

RSC->len 总数
| 2730573824. |
它几乎是2604MB。 但是、我们的系统具有2GB (DDR3)。
它是否会在内存不足时发生？ 它是否太危险？ 是否将我们的容量从2GB 增加到4GB？
我们在 rsc_table_vayu_dsp.h 上是否消除了任何(例如，DSP_tiler_mode_XX)无用信息？
我们的系统已按如下方式开发。
－三个显示屏
- 3D GPU、2D GPU -> GUI
->全高清视频解码
->摄像机编码
->使用 c66x 进行多音频处理。
非常感谢。
