Control: retitle -1 Pls. consider raspi-related configs for 5.10 Control: tags -1 + patch Control: block 968181 by 977441
Dear Debian kernel maintainers, CC: the Debian ARM list, Could you consider enabling the following kernel compilation options for Raspberry Pi 3&4 series for kernel 5.10? The patch is against latest package source at salsa.debian.org. --- debian/config/arm64/config-orig 2020-12-16 09:46:18.645380333 +0900 +++ debian/config/arm64/config 2020-12-16 10:22:17.998897582 +0900 @@ -424,6 +424,11 @@ ## file: drivers/gpu/drm/vc4/Kconfig ## CONFIG_DRM_VC4=m +CONFIG_DRM_VC4_HDMI_CEC=y +CONFIG_DRM_V3D=m +CONFIG_BCM_VIDEOCORE=m +CONFIG_BCM2835_VCHIQ=m +CONFIG_BCM2835_VCHIQ_MMAL=m ## ## file: drivers/gpu/host1x/Kconfig @@ -443,6 +448,7 @@ CONFIG_SENSORS_PWM_FAN=m CONFIG_SENSORS_SL28CPLD=m CONFIG_SENSORS_XGENE=m +CONFIG_SENSORS_RASPBERRYPI_HWMON=m ## ## file: drivers/hwspinlock/Kconfig @@ -1006,6 +1012,7 @@ CONFIG_PINCTRL_AMD=y CONFIG_PINCTRL_SINGLE=y CONFIG_PINCTRL_MAX77620=y +CONFIG_PINCTRL_BCM2835=y ## ## file: drivers/pinctrl/qcom/Kconfig @@ -1093,6 +1100,7 @@ ## file: drivers/reset/Kconfig ## CONFIG_RESET_CONTROLLER=y +CONFIG_RESET_RASPBERRYPI=m ## ## file: drivers/rpmsg/Kconfig @@ -1136,6 +1144,7 @@ ## file: drivers/soc/bcm/Kconfig ## CONFIG_RASPBERRYPI_POWER=y +CONFIG_BCM2835_POWER=y ## ## file: drivers/soc/fsl/Kconfig I have already built a Debian package with the above options from the latest master branch source on salsa.debian.org, and observed the following on RPi4: (1) CONFIG_DRM_V3D has no effect, as https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=977441#18 (2) HDMI display resolution can become 4K and fixing an important bug https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=968188 (3) /dev/dri/render* does not appear unlike https://bugs.launchpad.net/ubuntu/+source/linux-raspi/+bug/1880125/comments/14 https://bugs.launchpad.net/ubuntu/+source/linux-raspi2/+bug/1850876/comments/33 GPU/DRM acceleration remains unusable on RPi4, and bug 968181 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=968181 remains open. 968181 seems blocked by 977441. (4) My built Debian kernel 5.10.1 can boot from my usb mass storage device ID 04bb:0168 I-O Data Device, Inc. I-O DATA HDPH-UT but cannot access the root filesystem... My USB MSD mergenally worked with Debian kernel 5.9.* and can compile the Debian kernel package. My USB MSD requires periodical reset by the Debian kernel 5.9.*, which suggests this MSD is buggy... I ordered a faster SSD-based USB MSD. (5) Raspberry Pi Wireless cannot be used by my built Debian kernel 5.10.1. The wirelss has worked perfectly with Debian kernel 5.7--5.9. I will see what will happen with a Debian kernel package 5.10* both with and without proposed patch, and report it back, when it arrives in experimental or unstable. Bes regards, Ryutaroh Matsumoto
