tqr.gz of the OE package source to compile the test-glamo-dma userspace program

This package compiles a program named test-glamo-dma.

It lets you blit pixmaps to the screen to test the DMA based pixmap copying
feature of Xglamo/kernel.

To use it, you need to start the Xglamo server first, so that the command
processor is initialised.

Then you can do test-glamo-dma --do-mosaic 16x16, for instance, to blit a lot
of small pixmaps of size 16x16 onto the screen, drawing a mosaic. The pixmaps
would be blitted using DMA.
