#Hikey970 linux kernel driver
I think some of this is coming about because the DRM Driver isn’t working in the kernel.
Kernel-SRC/linux/drivers/gpu/drm/hisilicon/kirin9xx/kirin_fbdev.cĪ lot of people are angry because there is no linux driver for the Mali GPU. Kernel-SRC/linux/drivers/gpu/drm/hisilicon/kirin9xx/kirin_drm_drv.h Kernel-SRC/linux/drivers/gpu/drm/hisilicon/kirin9xx/kirin_drm_drv.c Kirin-drm e8600000.dpe: assigned reserved memory node drm_dma_mem_region ERROR Called for atomic driver, this is not what you want. But it looks like Canonical has already promoted the Linux 6.2 HWE kernel to existing.

Here are the differences i think are causing the issue.ĬAUSES NOT TO BUILD /* reset all the states of crtc/plane/encoder/connector */ My backlight on the monitor comes on but the display remains black. show originalĪfter all the patches are applied looking at my dmesg logs it looks pretty close to working. I’ve been playing with the kernel and implemented several patches as noted here. I am almost positive that the CMA is the cause of the display not working. What kernel source tree should be used for debain support?Ĭan someone help fix the CMA_BUFFER in the kernel srces. #define CMA_BUFFER_USED is required for the display to work. a/arch/arm64/boot/dts/hisilicon/hi3670-hikey970.Looking over my Dmesg & Uart logs I can conclude that We'll keep the 3v3 fixed regulator, as this will be usedīy the DRM/KMS driver. Used by the SD I/O to use the proper LDO supplies.
