QCM6490 fairphone is special case where same SOC is used for mobile product and it uses sc7280 memory map. Current patch adds support for the same SOC marketed for IOT segment [1] and very active in the development and soon going to freeze its memory map, so we are deriving memory map from sc7280 and creating a new memory map for all IOT product with qcm6490.dtsi .

I agree, but we are not changing anything for product which are there in the market instead defining a new memory map what is going to come with qcm6490.dtsi for IOT. Sorry, the other qcm6490 soc with fairphone(for mobile) can get confuse with qcm6490.dtsi but that is special case and i hope, that should be fine but, let me know if there is concern. > > With that, this really seems more of a change that would belong > in the IDP dts than the 6490-common one..

Stop reinventing the wheel. I'm not going to accept patches that are supposed to define ABI for products that are still in development. Not unless Qualcomm changes their attitude towards unilaterally breaking things for no good reason. > > [1] > https://www.qualcomm.com/products/internet-of-things/industrial/building-enterprise/qcm6490 > >> >> This SoC family has been on the market for quite some time, >> breaking software expectations like that is not cool, especially >> on a product with a promised lifespan of 10 years or whatever! > > I agree, but we are not changing anything for product which are there > in the market instead defining a new memory map what is going to come > with qcm6490.dtsi for IOT. Why would the OS care about the market segment you're targeting? Why would the firmware you're building care about the market segment you're targeting? The LE vs LA vs LU vs WP vs whatever split is so unnecessary and arbitrary on the firmware/kernel side.. The firmware should either be fully relocatable (so that dynamic memory reservation can be used), unified so that there's no changes or better yet stored in separate memory so that q6 cores don't steal the RAM that the user paid for and you can do whatever ugly magic you please in there. This arbitrary segmentation makes it impossible to have a common base, or to explain what device should go where to a newcomer.

And then what if you decide that you need to re-release SC7280 for automotive and make changes again? Do we define qcm6490au.dtsi which will redefine everything again-again? Konrad

First of all, I vented off on you very heavily in response to seeing something I don't like, even though you didn't have anything to do with it. Please accept my apology. There are some difficulties with integrating certain things upstream to work out on a broader scale, but me screaming at engineers in public won't help much with that. > Forgive me, if i ask some very basic question, just trying to put my > thought, > > I agree, OS should not worry about the market segment, but through the > DT firmware, we can better optimize memory to either give more memory to > user or give more memory to certain DSP's to enable certain feature > through the firmware like some logging infra etc., and due to which > certain gaps can get created where certain memory region need to be > move up or down due to increase in the carve-out. This is totally fine from a generic standpoint, however Qualcomm has a history (and you can see that in most SoC DTSIs) of having a common (or almost common) memory map on the vast majority of devices based on a given family of SoCs. We've been steadily taking advantage of that for quite some time. Here, we have an established compute SoC (7280-Chrome) with a memory setup that roughly matches its mobile counterpart (6490-LA or 778G or whatever different derivatives). IIUC you're tweaking the software for the "new IoT BSP" and resizing some regions resulted in many differences (as PIL regions tend to be contiguous one-to-another). The real issue here is that if we express this changed memory map in qcm6490.dtsi, all devices that have already shipped with the older-than-"new IoT BSP" software will differ rather significantly. You mentioned that there are going to be multiple users of *this new* configuration, perhaps qcm6490-iot-common.dtsi (similar to sc7280-chrome-common.dtsi) could facilitate the new bsp changes instead, making it less ambiguous. > > Let's say X Soc released with some memory map, any derivative SoC Y > should follow X's memory map if it is including X dtsi ? and the reason > why Y want to include X is solely the work done for X and most of > peripheral memory addresses is matching. > > But 'Y' could be different product, right? and it could have different > firmware and it is not like 'X' firmware will run on 'Y' ? Right, historically that hasn't happened very often but it could be like that. > Now a days, most of our firmware are relocatable. And we should totally take advantage of that. Stephan Gerhold has submitted some improvements that made it possible to dynamically allocate memory regions on 8916, this should probably be reused and expanded for other SoCs. Would it be possible for you to try out dynamic PIL region allocation on this board? See [1] for example. And the last thing is, I would like for you to give us some sort of a stability promise for this. You mentioned this SoC spin is "very active in the development", which makes me worried for DT compatibility with future METAs. We have unfortunately historically had to deal with different firmware packages behaving in divergent ways, and not always consistently between devices (but the last point may be just vendor modifications). We are supposed to be able to boot any future version of Linux with this initial devicetree, unless there's some fatal flaw that needs retroactive fixing (like when we tried to express LLCC as a contiguous region instead of a set of slices up until 8550 release or so). Please have that in mind, we've tried so hard to keep this ABI-like. And the last-last (I promise..) question, is this the final SoC silicon revision? And is it any different from the QCM6490 that has landed in some Android devices physically? Or does it simply ship with a different sw stack?
