Need help to build custom kernel 6.1

[slaver666]

Hi. Would help me with build custom kernel with dma-buf device.
I have Orange 5 Pi+ with Ubuntu server 24.04 kernel 6.1.
I need to run Android docker container https://github.com/CNflysky/redroid-rk3588 but have no /dev/dma_heap/system-uncached device.
I need to install Emby Server inside Android container and nothing more.
I see next config options in my current running system

DMABUF options

CONFIG_DMABUF_CACHE=y

CONFIG_RK_DMABUF_DEBUG is not set

CONFIG_DMABUF_PARTIAL is not set

CONFIG_SYNC_FILE=y
CONFIG_SW_SYNC=y
CONFIG_SW_SYNC_DEBUG=y

CONFIG_UDMABUF is not set

CONFIG_DMABUF_MOVE_NOTIFY is not set

CONFIG_DMABUF_DEBUG is not set

CONFIG_DMABUF_SELFTESTS is not set

CONFIG_DMABUF_HEAPS=y
CONFIG_DMABUF_SYSFS_STATS=y
CONFIG_DMABUF_HEAPS_SYSTEM=y
CONFIG_DMABUF_HEAPS_CMA=y

CONFIG_DMABUF_HEAPS_SRAM is not set

CONFIG_DMABUF_HEAPS_ROCKCHIP is not set

end of DMABUF options

Thanks.
