Hello,
Is it possible to use the Mali user space drivers on the Nexus 10 available at http://malideveloper.arm.com/develop-for-mali/drivers/mali-t6xx-gpu-user-space-drivers/ with stock Google firmware for OpenCL development? I don't want to change/debug the OS itself, so I don't think I should follow the guide at http://community.arm.com/docs/DOC-10124
If so, which exact firmware version is required for the r5p0-06rel0 drivers? The device has 3 different flavors of Android 5.0 available by Google (here: https://developers.google.com/android/nexus/images#mantaray - 5.0, 5.0.1 and 5.0.2), none of them seem to work with this driver properly, I get errors when calling OpenCL functions (usually CL_OUT_OF_HOST_MEMORY when calling clGetDeviceID), a similar thing I encountered when using nonworking Linux kernel + user space driver combination on a Samsung Chromebook 2, so I think (hope) the same happens here, and just need the correct combination.
What about the older r4p1-00rel0 / r4p0-02rel0 drivers, what exact firmware version should they work with?
My program works on both a Qualcomm-based Samsung Galaxy S5, and on a Samsung Chromebook 2, so both Android and Mali work (separately..), I am just missing a proper driver on the Nexus.
Thank you for your help,Robert
Hi psharma,
The list of public drivers we release can be found here:
http://malideveloper.arm.com/resources/drivers/arm-mali-midgard-gpu-user-space-drivers/
All of these drivers do support OpenCL with the exception of Nexus 10 drivers, and Juno r6p0.
Specifically for Android, it looks like your options are: Juno r5p0, and gem5 r8p0 currently, until we release the newer Nexus 10 drivers with CL support. Note that neither gem5 nor Juno are 'actual mobile or tablet' devices.
Note that this is just the list provided by us. There are plenty of production devices with Mali that have CL enabled, for example the Honor 7 comes to mind as one.
Kind Regards,
Michael McGeagh
