Latest developements seem to allow for reserving a block of memory on boot to be used as a device dedicated dma coherent memory. This may be required for videobuf_config based video drivers avoid problems with allocating dma coherent memory after system memory gets fragmented.
This set extends the OMAP1 camera resource initialization code with a function that can be used for reserving a block of memory early, then declared as the camera device dedicated dma coherent memory. An example use case is provided for Amstrad Delta camera. arch/arm/mach-omap1/board-ams-delta.c | 12 +++++++++- arch/arm/mach-omap1/devices.c | 36 ++++++++++++++++++++++++++++++ arch/arm/mach-omap1/include/mach/camera.h | 1 3 files changed, 48 insertions(+), 1 deletion(-) Thanks, Janusz -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
