CMA installation help or previous version workaround

[nyagaka]

Hi,

Installed the latest image on my SD card 2 or so weeks ago and in doing so I think I lost the CMA module on the Linux.

I tried using this makefile code (attached below) that Pavel wrote on his github forum a year ago but was unsucessful in that regard.

Code: Select all

obj-m += cma.o
KDIR = /lib/modules/$(shell uname -r)/build
all:
	make -C $(KDIR) M=$(shell pwd) modules
clean:
	make -C $(KDIR) M=$(shell pwd) clean

Is it possible for any assistance with installing CMA or pointing me in the direction of the last OS that had the CMA preinstalled as I wanted to try out the adc_recorder project and related ones that Pavel had made available and I need the CMA as he uses the ACP instead of the HP port?

never mind. Just noticed that Pavel stated in a previous post that the CMA driver is available only on his image.

Should've searched here before posting. Sorry about that
