Overclocking crust
In order to allocate more VRAM for the GPU you can add <code>cma=256</code> to your kernel (or use kconfig with CONFIG_CMA_SIZE_MBYTES=256) cmdline in boot.scr which you will have to compile using mkimage. By default the kernel allocates only 64MB, and the maximum value is 256MB.
Overclocking cedrus is achieved by modifying the kernel source code: https://elixir.bootlin.com/linux/latest/source/drivers/staging/media/sunxi/cedrus/cedrus.c#L507
