Need some help for compiling the DRM / Panfrost subtree code of JSM on the RockPro64 / Khadas Edge-V / RK3399

[ZioMario]

Hello.

I'm trying to compile the drm-subtree of JSM because I want to enable the panfrost driver on the RockPro64 / KHADAS EDGE-V / RK3399. The code is here :

GitHub - jsm222/drm-subtree: WIP drm drivers for FreeBSD

WIP drm drivers for FreeBSD. Contribute to jsm222/drm-subtree development by creating an account on GitHub.

github.com

he improved the old code,adding the modules. It works for FreeBSD 15-CURRENT. So,I've booted FreeBSD 14.2-RELEASE on the KHADAS EDGE-V board and I did :

marietto# git clone https://git.freebsd.org/src.git /usr/src
marietto# git clone https://github.com/jsm222/drm-subtree.git /usr/src/sys/dev/drm
marietto# cd /usr/src/sys/dev/drm/modules
marietto# make

and I get this error :

I edited the Makefile in the subdir /usr/src/sys/dev/drm/modules/rockchip/rk_vop :

KMOD     = rk_vop
DRMROOT?=./../../..
RKROOT?=${DRMROOT}/rockchip
SRCTOP?=/usr/src
SYSDIR?=${SRCTOP}/sys
.include "${SYSDIR}/conf/kern.opts.mk"
CFLAGS= -I${RKROOT}  -I${DRMROOT}/drmkpi/include/  -I${DRMROOT}/core/include/ -include ${DRMROOT}/drmkpi/include/drm/drm_os_freebsd.h -I${DRMROOT}/core/include/uapi/ -Wno-error=gnu-pointer-arith -DFDT -Wno-error=format
rk_vop_if.h:
    awk -f /usr/src/sys/tools/makeobjops.awk ${RKROOT}/rk_vop_if.m -h

with this :

KMOD     = rk_vop
DRMROOT?=./../../..
RKROOT?=${DRMROOT}/rockchip
SRCTOP?=/usr/src
SYSDIR?=${SRCTOP}/sys
.include "${SYSDIR}/conf/kern.opts.mk"

rk_vop_if.h:

SRCS=device_if.h bus_if.h vnode_if.h pci_if.h opt_platform.h ofw_bus_if.h clknode_if.h rk_vop_if.h fb_if.h phynode_if.h ${SYSDIR}/dev/drm/rockchip/rk_vop.c dw_hdmi_if.h ${SYSDIR}/dev/drm/rockchip/rk_plane.c

but I've got this new error :

# make

make "/usr/src/share/mk/bsd.dep.mk" line 201: $OBJS inside $SRCTOP not allowed : /usr/src/sys/dev/drm/rockchip/rk_vop.o /usr/src/sys/dev/drm/rockchip/rk_plane.o

I think the code to alter is inside /usr/src/share/mk/bsd.dep.mk :

But I don't know how. I'm not a coder,please,help me. Thanks.

Update 1 :

Asked to ChatGPT and solved with this code :

marietto# mkdir /root/rk_vop_mod
marietto# cd /root/rk_vop_mod
marietto# nano Makefile

KMOD    = rk_vop

# Point to FreeBSD source
SYSDIR  ?= /usr/src/sys

# Point to your drm-subtree sources
DRMROOT ?= /usr/src/sys/dev/drm
RKROOT  ?= ${DRMROOT}/rockchip

# Tell make where to search for these source files
.PATH: ${RKROOT}

          -DFDT \
          -Wno-error=gnu-pointer-arith \
          -Wno-error=format

but then,I've got these errors :

Do you have any solution for memory fragment? A year ago I also got the Panfrost driver working on a rock-pi4. But the graphical interface died pretty quickly. I was using Freebsd 14.
