Is there any plan for that merge? If yes, any timeline by which it will happen? If no, then can I use "imx_v8_defconfig" from linux-imx repo to build kernel using linux-fslc repo? * i.MX8 is supported in linux-imx_5.10.bb recipe https://github.com/Freescale/meta-freescale/blob/325ad529187fb1309b0a889c5196c8df039aeea9/recipes-ke...

It is providing v5.10.35 ( https://source.codeaurora.org/external/imx/linux-imx/log/?h=lf-5.10.y ) So ideally, just like v5.4 would like to use linux-fslc repo for v5.10 development as well.

Neither I can see any merge from NXP linux-imx branch "lf-5.10.y" into linux-fslc branch "5.10.x+fslc". When you say that i.MX8 is not supported - to which SoC you're referring to? Mainline kernel on the [master] branch of this layer does provide a descent support for all i.MX8M derivatives, but I'm not entirely sure of the state for i.MX8 family SoC support since I do not have that HW. Can you specify which derivative you're talking about? > Is there any plan for that merge? If yes, any timeline by which it will happen? I've looked into updating NXP branch [lf-5.10.y], and it is not trivial... I'm now short on time to have a full swing of merging the latest stable update on top of it, but probably would get to this eventually. If there are any volunteers here that are willing to undertake this task - this would be really appreciated. > If no, then can I use "imx_v8_defconfig" from linux-imx repo to build kernel using linux-fslc repo? You can use the `defconfig` file, which is present in the layer to build [linux-fslc] for i.MX8 machine. It resides in recipes-kernel/linux/linux-fslc/armv8a/defconfig and is synchronized with stable kernel release 5.14. If you however opt-in for [linux-fslc-lts] kernel package, then the kernel config file would be taken from recipes-kernel/linux/linux-fslc-lts/armv8a/defconfig, which is also synchronized with 5.10 from stable. Are there any specific configuration options you need from imx_v8_defconfig, which should be present in the defconfig for mainline recipes? > i.MX8 is supported in linux-imx_5.10.bb recipe https://github.com/Freescale/meta-freescale/blob/325ad529187fb1309b0a889c5196c8df039aeea9/recipes-ke... which is using kernel from branch "lf-5.10.y" provided by linux-imx repo but this repo is NXP internal and doesn't get updated with stable Linux kernel.

Andrey, By decent support for i.MX8M derivatives you mean no USB, no PCI, no DSI, no MIPI right? :) I haven't looked at the yocto kernel recipes but I spend a lot of time with the mainline kernel that I'm sure they are based on. While most of the power-domain stuff landed in 5.13 we are still waiting for blk-ctl which is needed to finish out the power-domain and reset control for all of those blocks unfortunately. > > Can you specify which derivative you're talking about? > > > Is there any plan for that merge?

Of course, there are few pieces that are missing in upstream kernel, which are present in the vendor one, but there are different opinion on the topic of "Vendor vs Vanilla" kernel, some tend to favor one for the other. My take on this is: if the functionality I need is present in upstream - I tend to use it, otherwise I take a vendor kernel (but would look for an option to have at least latest LTS patchset applied on it). This is strictly IMHO, and might not reflect the opinion of the others. :) > > I haven't looked at the yocto kernel recipes but I spend a lot of time > with the mainline kernel that I'm sure they are based on.

Correct, linux-fslc recipe on [master] branch does provide linux-5.14.y now with handful of patches on top. I'm not aware of those missing pieces you referred here, but your input here is pretty valuable! If you have any other constraints you're aware of - please share it here, or in the layer on GitHub. > > > > > Can you specify which derivative you're talking about? > > > > > Is there any plan for that merge?

I guess I would need to make a disclaimer here: I'm neither employed nor affiliated with NXP, so I cannot answer this. :) If there is a person from NXP on this list, then perhaps he/she can comment on this point. > > Best regards, > > Tim > > > > > > If no, then can I use "imx_v8_defconfig" from linux-imx repo to build kernel using linux-fslc repo? > > > > You can use the `defconfig` file, which is present in the layer to > > build [linux-fslc] for i.MX8 machine.

Someone else also mentioned to me that the NXP 'lf' releases are typically once every two years vs the 'imx' releases which are typically quarterly. Do you have any feedback on the prefix used in the commit messages used in both uboot-imx repos such as 'MLK', 'MA', 'LFU', 'LF', 'MMFMWK', 'MGS'? An understanding of those would make it easier for those of us who are working hard to mainline uboot/linux support. Best regards, Tim ^ permalink raw reply [flat|nested] 10+ messages in thread
