we use SGX544-MP2 core in Android P ,but we get crash on our app，it seem like something wrong in GPU。Can we get some suggestions to solve this question? this is our logcat when crash: 01-11 14:06:18.754 921 983 E IMGSRV : :0: PVRPMapKMem: mmap(2) failed: Mapping handle=0x2e6: Operation not permitted 01-11 14:06:18.754 921 983 E IMGSRV : :0: PVRSRVMapDeviceMem: PVRPMapKMem failed for buffer 01-11 14:06:18.754 921 983 E IMGSRV : :0: Failed to acquire CPU mapping for texture device memory 01-11 14:06:18.754 921 983 E IMGSRV : :0: PVRPMapKMem: mmap(2) failed: Mapping handle=0x2e6: Operation not permitted 01-11 14:06:18.754 921 983 E IMGSRV : :0: PVRSRVMapDeviceMem: PVRPMapKMem failed for buffer 01-11 14:06:18.754 921 983 E IMGSRV : :0: Failed to acquire CPU mapping for texture device memory --------- beginning of crash 01-11 14:06:18.755 921 983 F libc : Fatal signal 11 (SIGSEGV), code 1 (SEGV\_MAPERR), fault addr 0x0 in tid 983 (RenderThread), pid 921 (testdemo) 01-11 14:06:18.924 921 1773 W testdemo: Large object allocation failed: Failed anonymous mmap(0x0, 188416, 0x3, 0x2, 166, 0): Operation not permitted.

Hi, Ximeng. Welcome to our forum! The problem you describe looks like a out-of-memory situation. Are you able to run simpler OpenGL ES applications on your system? Are you handling returned errors when handling texture upload? Thanks. Carlos. ---

Hi,Carlos Thank you for reply. it seem works fine in a simpler OpenGL ES applications. We use Ti AM5728 cpu, our app also works fine on Android 5.1.1 SDK, but we need to upgrade Android system to Andoid P and those crash comes. and these crash on Android P in my app not happen everytime but high probabilty. so where can i get new version for .so like (libEGL\_POWERVR\_SGX544\_116.so\libGLESv2\_POWERVR\_SGX544\_116.so\libGLESv1\_CM\_POWERVR\_SGX544\_116.so)? by the way , i have asked ti for help ,but them had not supported Android SDK any more. ---

Hi, Ximeng. The drivers are built and distributed by our customers for their own platforms so, if TI have already said the do not support these drivers any longer, there is not much we can do. The issue above seems to be a problem with memory. I remember that the old Android puts a very stringent limit to the amount of memory an application can allocate. Maybe reducing the total memory allocated (e.g. smaller textures) could ease this problem. Regards. Carlos.
