Currently, I am developing my Own Video Frame Buffer Driver with help of Linux PCIe and Virtual Frame Buffer Driver.
My Custom Driver works fine on 720X480P Video Resolution but getting some slow on 720P Video Resolution.
I have just directly mapped frame buffer memory with DDR2 Memory coming with PCIe Interface on FPGA System.
DMA Controller Stuffs are implemented in FPGA System.
How can I develop DMA Read/Write Operation in my own frame buffer driver to solve my slow frame rate issue?
Please let me know if anyone has idea about this.
