Pre-requisites[edit]
Kernel(Linux PSP) versions supported or used for validation[edit]
Only the following devices have been tested & details below -
- AM335x & AM43x -
- Tree: git://git.ti.com/ti-linux-kernel/ti-linux-kernel.git
- Branch: ti-linux-3.12.y
- commit - a4daf45088f752ed6b33239026518fc3d1bce2bc
NOTE- 1.Ensure the reset controller driver is enabled in kernel menuconfig if not enabled by default as below- CONFIG_ARCH_HAS_RESET_CONTROLLER=y CONFIG_RESET_CONTROLLER=y CONFIG_RESET_TI=y
Toolchain[edit]
- Linaro 4.7.3 hardfp toolchain(arm-linux-gnueabihf-) was used for creating this release package.
What is supported[edit]
Khronos API support[edit]
- OpenGL ES 1.1
- OpenGL ES 2.0
- EGL
- Limited 2D acceleration via PVR2D API
Window Systems[edit]
The following Window Systems are supported, on Linux:
- Null Window System
Buffer Swap modes[edit]
The following modes of buffer swapping are supported,
- Front (1 buffer), Flip (chained buffers)
Selection of these modes is done via entries in /etc/powervr.ini. Please refer to http://processors.wiki.ti.com/index.php/SGXDbg#WindowSystem
Extensions[edit]
- IMG propreitary Bufferclass texture streaming enabled by default.
What is not supported[edit]
- Power Management features are not validated on AM43xx(due to an issue with DSS/frame buffer display not functional on issuing suspend/resume) - This will be validated on recieving the kernel sources with the fix and then appropriately this section will be updated.
- Kernel (for OMAP35x/AM35x/37xx) configured without DSS2 framework support will not work with the current display class driver.
- Xorg driver build (SUPPORT_XORG=1) not supported.
- Debug build is meant for debug/testing purposes only & should not be used for measuring performance.
[edit]
