I'd like to bring up this thread and discuss the option of not introducing another ARCH_* config: https://lore.kernel.org/all/20200306103652.GA3634389@kroah.com/ I especially don't like the "depends on ARCH_EXYNOS" because that forces one to include all the other Exynos drivers that ARCH_EXYNOS selects that Google Tensor SoCs don't need. Can we consider using SOC_GOOGLE instead and for all drivers that actually depend on the SoC hardware, we can just add "depends on SOC_GOOGLE"? The idea is that drivers should be tied to hardware -- not a specific vendor. By making drivers depend on ARCH_*, you are introducing an arbitrary vendor dependency and not a hardware dependency.

Can we consider using SOC_GOOGLE instead and for all SOC_GOOGLE will work exactly the same and depend on ARCH_EXYNOS or appear everywhere as ARCH_EXYNOS.

There is no arbitrary dependency. We call it all Exynos hardware, because this is Exynos. I remember what you were pushing for removal of ARCH_EXYNOS and there waas clear feedback, not only from me: this is against communities goals. > > Thanks, > Will Please trim the replies from unrelated context.

It helps all the people and distros who do not want to build/package drivers or modules for unrelated hardware or architectures. Let's take Samsung Exynos UART driver. It will never, 100% never, work on x86, x86_64. There is no single need to package it for kernels build for these products. It will not work on nVidia Tegra ARM64, Qualcomm ARM64 SoC, so if you do not want to run on Exynos, then you do no select ARCH_EXYNOS and have significantly smaller image. Now, there is no problem to have one kernel for nVidia Tegra + Qualcomm + Samsung Exynos with everything you need. The ARCH_EXYNOS or SOC_EXYNOS or SOC_GOOGLE serves only the purpose to allow distros and people customize build for specific hardware.

For the same reason above, because if I want to build kernel for Qualcomm, I want to drop easily anything not related. If I want to build kernel without I2C, I disable I2C bus which effectively disables all drivers which work on I2C. If I want to build kernel without Exynos, I disable ARCH_EXYNOS which effectively disables entire Exynos hardware. Think of SoC as a bus or interface. Best regards, Krzysztof

I'm glad you brought up Exynos UART because this is where one of the limitations is introduced. For example, if you want to modularize out all the vendor specific drivers from the core kernel to create a common arm64 kernel binary that works on all ARM64 devices, you will not be able to build in the early console UART drivers without enabling the respective ARCH_* configs. Being able to include SERIAL_SAMSUNG and SERIAL_MSM without all the vendor specific drivers that ARCH_EXYNOS and ARCH_QCOM select is very valuable for debugging early boot issues. I understand that ARCH_* configs are used to selectively pick which device tree blobs are built, but forcing developers to pick all or nothing is where I have a problem.

When you build single kernel there is never need to NOT ENABLE respective ARCH configs. Please describe me upstream case for such need to NOT ENABLE. > Being able to include SERIAL_SAMSUNG and SERIAL_MSM without all the vendor> specific drivers that ARCH_EXYNOS and ARCH_QCOM select is very valuable for > debugging early boot issues. Really? How related? The drivers are independent. You describe some out-of-tree development process which we never needed for upstream work. And we did here quite a lot of upstream, specially if you look at ARCH_QCOM. > > I understand that ARCH_* configs are used to selectively pick which device tree > blobs are built, but forcing developers to pick all or nothing is where I have > a problem. No one forces you to pick up everything or nothing. You select ARCH_EXYNOS and still can drop all optional drivers. It's true you cannot drop mandatory drivers, but you are upstreaming Exynos platform, right? We do not talk about your out-of-tree Google work because it does not matter. Best regards, Krzysztof

Right: in general, all drivers are independent of the platform besides the typical 'depends on ARCH_FOO || COMPILE_TEST' dependency, but I think it's worth mentioning the known exceptions, so Greg and Will can take that fight to the respective places rather than discussing it in the platform submission: - Some subsystems are considered 'special' and the maintainers prefer the drivers to be automatically selected based on the ARCH_* settings instead of having user-visible options. This is traditionally true for large chunks of drivers/irqchip, drivers/clocksource and drivers/pinctrl, though it has gotten better over time on all of them. - Some older 32-bit platforms are still not as modular as we'd like them to be, especially the StrongARM (ARMv4) platforms that require a custom kernel build, and some of ARMv4T and ARMv5 boards that are still missing DT support. These tend to require drivers they directly link to from board code, so disabling the drivers would cause a link failure until this gets cleaned up. - A couple of drivers are force-enabled based on the ARCH_* options because booting without these drivers would risk permanent damage to hardware, e.g. in overtemp or overcurrent scenarios. - ACPI based platforms require the PCI host bridge driver to be built-in rather than a loadable module because ACPI needs to probe PCI devices during early boot. - Some subsystems (notably drivers/gpu/, but others as well) have an excessive number of 'select' statements, so you end up surprise-enabling a number of additional drivers and subsystems by enabling certain less important platform specific drivers.

My last question then is -- why do we need a new ARCH_GOOGLE_TENSOR config in the platform Kconfig? For example, I don't really like this: diff --git a/drivers/clk/samsung/Kconfig b/drivers/clk/samsung/Kconfig index 76a494e95027..4c8f173c4dec 100644 --- a/drivers/clk/samsung/Kconfig +++ b/drivers/clk/samsung/Kconfig @@ -13,6 +13,7 @@ config COMMON_CLK_SAMSUNG select EXYNOS_5420_COMMON_CLK if ARM && SOC_EXYNOS5420 select EXYNOS_ARM64_COMMON_CLK if ARM64 && ARCH_EXYNOS select TESLA_FSD_COMMON_CLK if ARM64 && ARCH_TESLA_FSD + select GOOGLE_GS101_COMMON_CLK if ARM64 && ARCH_GOOGLE_TENSOR What happens when we have GOOGLE_GS101_COMMON_CLK, GOOGLE_GS201_COMMON_CLK, and so on? How are we going to pick the right driver when we have a generic ARCH_GOOGLE_TENSOR config? Ideally, we should have one Exynos clock driver that can detect what hardware is running (using the DT) to determine what it needs to do. If you really want to compile out the other vendor's clock drivers using some configs, then we should do that with SOC_GS101, SOC_GS201, SOC_TESLA_FSD configs (not ideal though). With that approach, we could drop the platform ARCH_GOOGLE_TENSOR config and create an SOC_GS101 config that can be used for things like the COMMON_CLK_SAMSUNG driver (for now) and building the GS101 dtb. Let me know your thoughts. Thanks, Will

Google gs101 SoC is ARMv8 mobile SoC found in the Pixel 6, (oriole) Pixel 6a (bluejay) and Pixel 6 pro (raven) mobile phones. It features: * 4xA55 little cluster * 2xA76 Mid cluster * 2xX1 Big cluster This commit adds the basic device tree for gs101 (SoC) and oriole (pixel 6). Further platform support will be added over time. It has been tested with a minimal busybox initramfs and boots to a shell.
