* of: fdt: Honor CONFIG_CMDLINE* even without /chosen node, take 2Rob Herring2023-01-041-13/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I do not read a strict requirement on /chosen node in either ePAPR or in Documentation/devicetree. Help text for CONFIG_CMDLINE and CONFIG_CMDLINE_EXTEND doesn't make their behavior explicitly dependent on the presence of /chosen or the presense of /chosen/bootargs. However the early check for /chosen and bailing out in early_init_dt_scan_chosen() skips CONFIG_CMDLINE handling which is not really related to /chosen node or the particular method of passing cmdline from bootloader. This leads to counterintuitive combinations (assuming CONFIG_CMDLINE_EXTEND=y): a) bootargs="foo", CONFIG_CMDLINE="bar" => cmdline=="foo bar" b) /chosen missing, CONFIG_CMDLINE="bar" => cmdline=="" c) bootargs="", CONFIG_CMDLINE="bar" => cmdline==" bar" Rework early_init_dt_scan_chosen() so that the cmdline config options are always handled.

| | | | | | | | | | | | | | This reverts commit a7d550f82b445cf218b47a2c1a9c56e97ecb8c7a. Some arches (PPC at least) don't call early_init_dt_scan_nodes(), so moving the cmdline processing there breaks them.

* of/fdt: run soc memory setup when early_init_dt_scan_memory failsAndreas Rammhold2023-01-031-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | If memory has been found early_init_dt_scan_memory now returns 1. If it hasn't found any memory it will return 0, allowing other memory setup mechanisms to carry on. Previously early_init_dt_scan_memory always returned 0 without distinguishing between any kind of memory setup being done or not. Any code path after the early_init_dt_scan memory call in the ramips plat_mem_setup code wouldn't be executed anymore. Making early_init_dt_scan_memory the only way to initialize the memory. Some boards, including my mt7621 based Cudy X6 board, depend on memory initialization being done via the soc_info.mem_detect function pointer. Those wouldn't be able to obtain memory and panic the kernel during early bootup with the message "early_init_dt_alloc_memory_arch: Failed to allocate 12416 bytes align=0x40".

The "big" change in here is the addition of a new macro, container_of_const() that will preserve the "const-ness" of a pointer passed into it. The "problem" of the current container_of() macro is that if you pass in a "const *", out of it can comes a non-const pointer unless you specifically ask for it. For many usages, we want to preserve the "const" attribute by using the same call. For a specific example, this series changes the kobj_to_dev() macro to use it, allowing it to be used no matter what the const value is. This prevents every subsystem from having to declare 2 different individual macros (i.e. kobj_const_to_dev() and kobj_to_dev()) and having the compiler enforce the const value at build time, which having 2 macros would not do either. The driver for all of this have been discussions with the Rust kernel developers as to how to properly mark driver core, and kobject, objects as being "non-mutable". The changes to the kobject and driver core in this pull request are the result of that, as there are lots of paths where kobjects and device pointers are not modified at all, so marking them as "const" allows the compiler to enforce this. So, a nice side affect of the Rust development effort has been already to clean up the driver core code to be more obvious about object rules. All of this has been bike-shedded in quite a lot of detail on lkml with different names and implementations resulting in the tiny version we have in here, much better than my original proposal. Lots of subsystem maintainers have acked the changes as well. Other than this change, included in here are smaller stuff like: - kernfs fixes and updates to handle lock contention better - vmlinux.lds.h fixes and updates - sysfs and debugfs documentation updates - device property updates All of these have been in the linux-next tree for quite a while with no problems" * tag 'driver-core-6.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: (58 commits) device property: Fix documentation for fwnode_get_next_parent() firmware_loader: fix up to_fw_sysfs() to preserve const usb.h: take advantage of container_of_const() device.h: move kobj_to_dev() to use container_of_const() container_of: add container_of_const() that preserves const-ness of the pointer driver core: fix up missed drivers/s390/char/hmcdrv_dev.c class.devnode() conversion. driver core: fix up missed scsi/cxlflash class.devnode() conversion. driver core: fix up some missing class.devnode() conversions. driver core: make struct class.devnode() take a const * driver core: make struct class.dev_uevent() take a const * cacheinfo: Remove of_node_put() for fw_token device property: Add a blank line in Kconfig of tests device property: Rename goto label to be more precise device property: Move PROPERTY_ENTRY_BOOL() a bit down device property: Get rid of __PROPERTY_ENTRY_ARRAY_EL*SIZE*() kernfs: fix all kernel-doc warnings and multiple typos driver core: pass a const * into of_device_uevent() kobject: kset_uevent_ops: make name() callback take a const * kobject: kset_uevent_ops: make filter() callback take a const * kobject: make kobject_namespace take a const * ...

Ideally, the size should be based on '#address-cells', but that has never been enforced in the kernel's FDT boot parsing code (early_init_dt_check_for_initrd()). Bootloader behavior is known to vary. For example, kexec always writes these as 64-bit. The result of incorrectly reading 32-bit values is most likely the reserved memory for the original initrd will still be reserved for the new kernel. The original arm64 equivalent of this code failed to release the initrd reserved memory in *all* cases. Use of_read_number() to mirror the early_init_dt_check_for_initrd() code.

While we have occasionally merged support for non-arm SoCs in the past, this is now the normal path for riscv devicetree files. The most notable changes, by SoC platform, are: - The Apple T6000 (M1 Pro), T6001 (M1 Max) and T6002 (M1 Ultra) chips now have initial support. This is particularly nice as I am typing this on a T6002 Mac Studio with only a small number of driver patches. - Qualcomm MSM8996 Pro (Snapdragon 821), SM6115 (Snapdragon 662), SM4250 (Snapdragon 460), SM6375 (Snapdragon 695), SDM670 (Snapdragon 670), MSM8976 (Snapdragon 652) and MSM8956 (Snapdragon 650) are all mobile phone chips that are closely related to others we already support. Adding those helps support more phones and we add several models from Sony (Xperia 10 IV, 5 IV, X, and X compact), OnePlus (One, 3, 3T, and Nord N100), Xiaomi (Poco F1, Mi6), Huawei (Watch) and Google (Pixel 3a). There are also new variants of the Herobrine and Trogdor chromebook motherboards. SA8540P is an automotive SoC used in the Qdrive-3 development platform - Rockchips gains no new SoC variants, but a lot of new boards: three mobile gaming systems based on RK3326 Odroid-Go/rg351 family, two more Anbernic gaming systems based on RK3566 and a number of other RK356x based single-board computers. - Renesas RZ/G2UL (r9a07g043) was already supported for arm64, but as the newly added RZ/Five is based on the same design, this now gets reorganized in order to share most of the dts description between the two and add the RZ/Five SMARC EVK board support. Aside from that, there are the usual changes all over the tree: - New boards on other platforms contain two ASpeed BMC users, two Broadcom based Wifi routers, Zyxel NSA310S NAS, the i.MX6 based Kobo Aura2 ebook reader, two i.MX8 based development boards, two Uniphier Pro5 development boards, the STM32MP1 testbench board from DHCOR, the TI K3 based BeagleBone AI-64 board, and the Mediatek Helio X10 based Sony Xperia M5 phone. - The Starfive JH7100 source gets reorganized in order to support the VisionFive V1 board. - Minor updates and cleanups for Intel SoCFPGA, Marvell PXA168, TI, ST, NXP, Apple, Broadcom, Juno, Marvell MVEBU, at91, nuvoton, Tegra, Mediatek, Renesas, Hisilicon, Allwinner, Samsung, ux500, spear, ...

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 951d48855d86 ("of: Make of_dma_get_range() work on bus nodes") relaxed the handling of "dma-ranges" for any leaf node on the assumption that it would still represent a usage error for the property to be present on a non-bus leaf node. However there turns out to be a fiddly case where a bus also represents a DMA-capable device in its own right, such as a PCIe root complex with an integrated DMA engine on its platform side. In such cases, "dma-ranges" translation is entirely valid for devices discovered behind the bus, but should not be erroneously applied to the bus controller device itself which operates in its parent's address space. Fix this by restoring the previous behaviour for the specific case where a device is configured via its own OF node, since it is logical to assume that a device should never represent its own parent bus.

U-Boot, are so that start > end, then the phys_initrd_size calculated from end - start is negative that subsequently gets converted to a high positive value for being unsigned long long. Then, the memory region with the (invalid) size is added to the bootmem and attempted being paged in paging_init() that results in the kernel fault. For example, on the FVP ARM64 system I'm running, the U-Boot populates the 'linux,initrd-start' with 8800_0000 and 'linux,initrd-end' with 0. The phys_initrd_size calculated is then ffff_ffff_7800_0000 (= 0 - 8800_0000 = -8800_0000 + ULLONG_MAX + 1). paging_init() then attempts to map the address 8800_0000 + ffff_ffff_7800_0000 and oops'es as below. It should be stressed, it is generally a fault of the bootloader's with the kernel relying on it, however we should not allow the bootloader's misconfiguration to lead to the kernel oops. Not only the kernel should be bullet proof against it but also finding the root cause of the paging fault spanning over the bootloader, DT, and kernel may happen is not so easy.

This way driver authors are not tempted to assume that passing an error to the upper layer is a good idea. All drivers are adapted accordingly. There is no intended change of behaviour, all callbacks were prepared to return 0 before.

It implements using the cache-management instructions from the Zicbom- extension to handle cache flush, etc actions on platforms needing them. SoCs using cpu cores from T-Head like the Allwinne D1 implement a different set of cache instructions. But while they are different, instructions they provide the same functionality, so a variant can easly hook into the existing alternatives mechanism on those.

So modify the function to also check for dma-noncoherent and set a suitable default return value. If CONFIG_OF_DMA_DEFAULT_COHERENT is set the value starts with true and finding dma-noncoherent will set it to false and without CONFIG_OF_DMA_DEFAULT_COHERENT, the behaviour is reversed.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the earlycon parameter is given twice, the kernel will spit out a WARN() in register_console() because it was already registered. The non-dt variant setup_earlycon() already handles that gracefully. The dt variant of_setup_earlycon() doesn't. Add the check there and add the -EALREADY handling in early_init_dt_scan_chosen_stdout(). FWIW, this doesn't happen if CONFIG_ACPI_SPCR_TABLE is set.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We should use of_node_put() for the reference 'node' returned by of_parse_phandle() which will increase the refcount.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On the ->remove() stage the callback uses physical device node instead of one from GPIO chip and the variable name which is different to one used in unittest_gpio_probe(). Make these consistent with unittest_gpio_probe().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The OF node in the GPIO library is deprecated and soon will be removed. GPIO library now accepts fwnode as a firmware node, so switch the module to use it instead.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the allocation/reservation of reserved-memory fails, it is normally an error, so print it as an error so that it doesn't get hidden from the console due to the loglevel. Also make the allocation failure include the size just like the reservation failure.
