I think it's fairly safe, and it's been upstream and enabled there for a while, but of course you never know... If this has to end up in the first point release after bullseye then that's fair enough.

This really starts to become late for the bullseye release, so we need to be careful enough. We will see what we can do. Regards, Salvatore

Source: linux Version: 5.10.26-1 Followup-For: Bug #985862 Testing 5.10.26-1 on a Compulab IOT-gateway board (https://www.compulab.com/products/iot-gateways/iot-gate-imx8-industrial-arm-iot-gateway/) revealed that a couple more config options are needed to support it: CONFIG_SERIAL_IMX_CONSOLE=y CONFIG_CLK_IMX8MM=y Without these it hangs early in the boot process. (Whilst they can be configured as modules this doesn't work well. CONFIG_SERIAL_IMX_CONSOLE=m misses quite alot of the boot messages and CONFIG_CLK_IMX8MM=m just makes it hang.) (Thanks to Vincent for the testing) Enabling these in the next upload, whenever that is, would be much appreciated. Addendum: There are almost certainly some other clocks needed for other hardware, but that needs to await testing/feedback from people with access to said hardware. Just for future reference: I believe the correspondance of config options to SOC variants is: IMX8MN == i.MX8M Nano IMX8MQ == i.MX8M Quad IMX8QXP == i.MX8 QuadXPlus IMX8MP == i.MX8M Plus -- Wookey

Source: linux Severity: normal The iMX8 SoC is used on various boards, widely available to debian users and well supported by free software, but the platform is not enabled in debian kernels, which is a rather major omission. I don't know why not (I guess no-one filed this bug?). These are all avilable today and should at least mostly work with mainline: Nitrogen 8M https://boundarydevices.com/product/nitrogen8m/ Solidrun Cubox M https://shop.solid-run.com/product/SRMP8QDWB1D04GE008X00CE/ Hummingboard Pulse https://shop.solid-run.com/product-category/embedded-computers/nxp-family/hummingboard-m/ Purism Librem 5 Phone https://en.wikipedia.org/wiki/Librem_5 Compulab SBC-iMX8X https://www.compulab.com/products/sbcs/sbc-imx8x-nxp-i-mx-8x-single-board-computer/ (supported since 5.4.24) Toradex Apalis iMX8 CoM https://www.toradex.com/computer-on-modules/apalis-arm-family/nxp-imx-8 I believe that all that is needed is adding CONFIG_ARCH_MXC=y in debian/config/arm64/config Which is set by default upstream. (There may be other drivers that should enabled too for some of these platforms?) I just built the kernel with the above config change and it builds fine on arm64, and installs and boots on softiron. I don't have an iMX8 here to test on, but we can find some, I'm sure. It seems like the timing was rather unfortunate here with some of this hardware only becoming widely available in Q4 2020 (shortly before the Bullseye freeze). Is there any chance of one more hardware enablement upload for bullseye, or does this feel like too big a change? If not, getting this into a point release would make debian stable useful on a lot more hardware. What testing would make the kernel team reasonably happy about doing that? -- Wookey
