Hello
Arm Compiler 5 is a very old version. To use this, you would need MDK Professional Edition, and from there, generate a legacy license. See the below:

asked a question in9 days agoVulkan memory type for immutable vertex/index buffers
Hi.
What is the recommended Vulkan memory type for immutable vertex/index buffers?
According to Arm Mali GPU Best Practices - the best memory type for that kind of usage (immutable resources) should have only HOST_VISIBLE | HOST_COHERENT bits.
Does that...
Thank you for the answer! One more thing I wanted to clarify - does that mean that there is no need at all to use DEVICE_LOCAL bit on ARM mobile systems?
Or would be there a benefit for having DEVICE_LOCAL | HOST_VISIBLE combination?
does that mean that there is no need at all to use DEVICE_LOCAL bit on ARM mobile systems?
There is no memory heap that is not DEVICE_LOCAL.
Does Mali-Immortalis-G715 MC11 support EGL_EXT_image_dma_buf_import?
Do newer Mali GPUs support the EGL_EXT_image_dma_buf_import extension?
I noticed that my Mali-Immortalis-G715 MC11 (used in the Oppo Find X6) does not support this extension.
Thanks.
Hi Peter, thanks for your reply.
I am just confused about the document I've read from here:
developer.arm.com/.../EGL-EXT-image-dma-buf-import
It mentions that: The DDK supports the EGL_EXT_image_dma_buf_import extension on all the Linux variants and also on Android.
The native driver supports it, but EGL implementation on Android is filtered by Android itself, so it's possible that the extension is getting stripped by the Android implementation before the application sees it.
Android really wants developers to use gralloc for managing surface allocation, rather than raw dmabuf, so where possible allocate an Android native image via gralloc and import it into EGL using eglCreateImageKHR(..., EGL_ANDROID_image_native_buffer, ...).

Can you help?
