| * | ARM: add multi_v7_lpae_defconfigNicolas Saenz Julienne2023-01-241-0/+6
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The only missing configuration option preventing us from using multi_v7_defconfig with the Raspberry Pi 4 is ARM_LPAE. It's needed as the PCIe controller found on the SoC depends on 64bit addressing, yet can't be included as not all v7 boards support LPAE. Introduce multi_v7_lpae_defconfig, built off multi_v7_defconfig, which will avoid us having to duplicate and maintain multiple similar configurations. Needless to say the Raspberry Pi 4 is not the only platform that can benefit from this new configuration.

|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 1d2e9b67b001 ("ARM: 9265/1: pass -march= only to compiler") added a __thumb2__ define to ASFLAGS to avoid build errors in the crypto code, which relies on __thumb2__ for preprocessing. Commit 59e2cf8d21e0 ("ARM: 9275/1: Drop '-mthumb' from AFLAGS_ISA") followed up on this by removing -mthumb from AFLAGS so that __thumb2__ would not be defined when the default target was ARMv7 or newer. Unfortunately, the second commit's fix assumes that the toolchain defaults to -mno-thumb / -marm, which is not the case for Debian's arm-linux-gnueabihf target, which defaults to -mthumb: $ echo | arm-linux-gnueabihf-gcc -dM -E - | grep __thumb #define __thumb2__ 1 #define __thumb__ 1 This target is used by several CI systems, which will still see redefined macro warnings, despite '-mthumb' not being present in the flags: <command-line>: warning: "__thumb2__" redefined <built-in>: note: this is the location of the previous definition Remove the global AFLAGS __thumb2__ define and move it to the crypto folder where it is required by the imported OpenSSL algorithms; the rest of the kernel should use the internal CONFIG_THUMB2_KERNEL symbol to know whether or not Thumb2 is being used or not. Be sure that __thumb2__ is undefined first so that there are no macro redefinition warnings.

Debian carries a downstream patch that changes the default CPU of the arm-linux-gnueabihf target from 'arm1176jzf-s' (v6) to 'cortex-a7' (v7). As a result, '-mthumb' defines both '__thumb__' and '__thumb2__'. The define of '__thumb2__' via the command line was purposefully added to catch a situation like this. In a similar vein as commit 26b12e084bce ("ARM: 9264/1: only use -mtp=cp15 for the compiler"), do not add '-mthumb' to AFLAGS_ISA, as it is already passed to the assembler via '-Wa,-mthumb' and '__thumb2__' is already defined for preprocessing.

Split the arch-y make variable into two, so that -march= flags only get passed to the compiler, not the assembler. -D flags are added to KBUILD_CPPFLAGS which is used for both C and assembler-with-cpp sources. Clang is trying to warn that it doesn't support different values for -march= and -Wa,-march= (like GCC does, but the kernel doesn't need this) though the value of the preprocessor define __thumb2__ is based on -march=. Make sure to re-set __thumb2__ via -D flag for assembler sources now that we're no longer passing -march= to the assembler. Set it to a different value than the preprocessor would for -march= in case -march= gets accidentally re-added to KBUILD_AFLAGS in the future. Thanks to Ard and Nathan for this suggestion.

Conventionally, we do this for head*.S, which contains the kernel entry point. A counter approach is to control the section order by the linker script. Actually, the code marked as __HEAD goes into the ".head.text" section, which is placed before the normal ".text" section. I do not know if both of them are needed. From the build system perspective, head-y is not mandatory. If you can achieve the proper code placement by the linker script only, it would be cleaner. I collected the current head-y objects into head-object-list.txt. It is a whitelist. My hope is it will be reduced in the long run.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are a number of old Makefile.boot files that remain from the multiplatform conversion, and three that are still in use. These provide the "ZRELADDR", "PARAMS_PHYS" and "INITRD_PHYS" values that are platform specific. It turns out that we can generally just derive this from information that is available elsewhere: - ZRELADDR is normally detected at runtime with the CONFIG_AUTO_ZRELADDR flag, but also needed to be passed to for 'make uImage'. In a multiplatform kernel, one always has to pass this as the $(LOADADDR) variable, but in the StrongARM kernels we can derive it from the sum of $(CONFIG_PHYS_OFFSET) and $(TEXT_OFFSET) that are already known. - PARAMS_PHYS and INITRD_PHYS are only used for bootpImage, which in turn is only used for the pre-ATAGS 'param_struct' based boot interface on StrongARM based machines with old boot loaders. They can both be derived from CONFIG_PHYS_OFFSET and a machine specific offset for the initrd, so all of the logic for these can be part of arch/arm/boot/bootp/Makefile.

However, work is underway to get this implemented in the compiler, which means we will be able to deprecate the GCC plugin at some point.

The best way forward that I see is to just remove all the checks, which also has the nice side-effect of slightly improving the startup time for 'make'. The -mtune=marvell-f option was apparently never supported by any mainline compiler, and the custom Codesourcery gcc build that did support is now too old to build kernels, so just use -mtune=xscale unconditionally for those. This should be safe to apply on all stable kernels, and will be required in order to keep building them with gcc-11 and higher.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that the user space TLS register is assigned on every return to user space, we can use it to keep the 'current' pointer while running in the kernel. This removes the need to access it via thread_info, which is located at the base of the stack, but will be moved out of there in a subsequent patch. Use the __builtin_thread_pointer() helper when available - this will help GCC understand that reloading the value within the same function is not necessary, even when using the per-task stack protector (which also generates accesses via the TLS register). For example, the generated code below loads TPIDRURO only once, and uses it to access both the stack canary and the preempt_count fields. <do_one_initcall>: e92d 41f0 stmdb sp!, {r4, r5, r6, r7, r8, lr} ee1d 4f70 mrc 15, 0, r4, cr13, cr0, {3} 4606 mov r6, r0 b094 sub sp, #80 ; 0x50 f8d4 34e8 ldr.w r3, [r4, #1256] ; 0x4e8 <- stack canary 9313 str r3, [sp, #76] ; 0x4c f8d4 8004 ldr.w r8, [r4, #4] <- preempt count Co-developed-by: Keith Packard <keithpac@amazon.com> Signed-off-by: Keith Packard <keithpac@amazon.com> Signed-off-by: Ard Biesheuvel <ardb@kernel.org> Reviewed-by: Linus Walleij <linus.walleij@linaro.org> Tested-by: Amit Daniel Kachhap <amit.kachhap@arm.com>
* | gcc-plugins: arm-ssp: Prepare for THREAD_INFO_IN_TASK supportArd Biesheuvel2021-09-271-4/+1
|/ | | | | | | | | | | | | | | | | | | We will be enabling THREAD_INFO_IN_TASK support for ARM, which means that we can no longer load the stack canary value by masking the stack pointer and taking the copy that lives in thread_info. Instead, we will be able to load it from the task_struct directly, by using the TPIDRURO register which will hold the current task pointer when THREAD_INFO_IN_TASK is in effect. This is much more straight-forward, and allows us to declutter this code a bit while at it. Note that this means that ARMv6 (non-v6K) SMP systems can no longer use this feature, but those are quite rare to begin with, so this is a reasonable trade off.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Ericsson U300 platform was one of two ARM929 based SoC platforms for mobile phones in ST-Ericsson after the merger of Ericsson with ST-NXP into ST-Ericsson, the other one being the ST Nomadik. The platform was not widely adopted in Linux based systems and was replaced with the far superior ST-Ericsson U8500 in 2011, but Linus Walleij kept maintaining the code for the whole time. Linus continues to use the Nomadik machine, but decided to drop u300 from the kernel as part of this year's spring cleaning. Thanks for having maintained it all these years.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The smp8758 (tango4) SoC was the last generation of set-top-box chips to come out of Sigma Designs, and support was added by Marc Gonzalez and Måns Rullgård between 2015 and 2017, before the company went out of business and the products were abandoned. The chip is used in some set-top-boxes such as the Popcorn Hour A-500, which could have seen some adoption by hobbyists. This has not happened in the past four years, and support for the more widely used MIPS based SoCs was never merged at all. Thanks to Marc and Måns for maintaining for the past years even after the death of the platform.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ZTE ZX set-top-box SoC platform was added in 2015 by Jun Nie, with Baoyou Xie and Shawn Guo subsequently becoming maintainers after the addition of the 64-bit variant. However, the only machines that were ever supported upstream are the reference designs, not actual set-top-box devices that would benefit from this support. All ZTE set-top-boxes from the past few years seem to be based on third-party SoCs. While there is very little information about zx296702 and zx296718 on the web, I found some references to other chips from the same family, such as zx296716 and zx296719, which were never submitted for upstream support. Finally, there is no support for the GPU on either of them, with the lima and panfrost device drivers having been added after work on the zx platform had stopped. Shawn confirmed that he has not seen any interest in this platform for the past four years, and that it can be removed. Thanks to Jun and Shawn for maintaining this platform over the past five years.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The SiRF Prima2 and Atlas platform code was contributed by Cambridge Silicon Radio (CSR) after aquiring the original SiRF company, and maintained by Barry Song. CSR was subsequently acquired by Qualcomm, who no longer have an interest in maintaining the SoC platform but instead have released more recent SoCs for the same market in the Snapdragon family. As Barry is no longer working for the company, nobody else there wants to maintain it, and there are no third-party users, the best way forward seems to be to completely remove it. Thanks to Barry for maintaining the platform for the past ten years.
