Pull RISC-V updates from Palmer Dabbelt: "This contains a handful of new features: - Partial support for the Kendryte K210. There are still a few outstanding issues that I have patches for, but I don't actually have a board to test them so they're not included yet. - SBI v0.2 support. - Fixes to support for building with LLVM-based toolchains. The resulting images are known not to boot yet. I don't anticipate a part two, but I'll probably have something early in the RCs to finish up the K210 support" * tag 'riscv-for-linus-5.7' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux: (38 commits) riscv: create a loader.bin boot image for Kendryte SoC riscv: Kendryte K210 default config riscv: Add Kendryte K210 device tree riscv: Select required drivers for Kendryte SOC riscv: Add Kendryte K210 SoC support riscv: Add SOC early init support riscv: Unaligned load/store handling for M_MODE RISC-V: Support cpu hotplug RISC-V: Add supported for ordered booting method using HSM RISC-V: Add SBI HSM extension definitions RISC-V: Export SBI error to linux error mapping function RISC-V: Add cpu_ops and modify default booting method RISC-V: Move relocate and few other functions out of __init RISC-V: Implement new SBI v0.2 extensions RISC-V: Introduce a new config for SBI v0.1 RISC-V: Add SBI v0.2 extension definitions RISC-V: Add basic support for SBI v0.2 RISC-V: Mark existing SBI as 0.1 SBI. riscv: Use macro definition instead of magic number riscv: Add support to dump the kernel page tables ...

riscv: create a loader.bin boot image for Kendryte SoC

2020-04-03T17:50:17Z

Create the loader.bin bootable image file that can be loaded into Kendryte K210 based boards using the kflash.py tool with the command: kflash.py/kflash.py -t arch/riscv/boot/loader.bin Signed-off-by: Christoph Hellwig Signed-off-by: Damien Le Moal Reviewed-by: Anup Patel Reviewed-by: Palmer Dabbelt Signed-off-by: Palmer Dabbelt

riscv: Change code model of module to medany to improve data accessing

2020-03-03T18:27:46Z

All the loaded module locates in the region [＆_end-2G，VMALLOC_END] at runtime, so the distance from the module start to the end of the kernel image does not exceed 2GB. Hence, the code model of the kernel module can be changed to medany to improve the performance data access. Signed-off-by: Vincent Chen Signed-off-by: Palmer Dabbelt

riscv: provide a flat image loader

2019-11-17T23:17:39Z

This allows just loading the kernel at a pre-set address without qemu going bonkers trying to map the ELF file. Contains a contribution from Aurabindo Jayamohanan to reuse the PAGE_OFFSET definition.

Pull Kbuild updates from Masahiro Yamada: - add modpost warn exported symbols marked as 'static' because 'static' and EXPORT_SYMBOL is an odd combination - break the build early if gold linker is used - optimize the Bison rule to produce .c and .h files by a single pattern rule - handle PREEMPT_RT in the module vermagic and UTS_VERSION - warn CONFIG options leaked to the user-space except existing ones - make single targets work properly - rebuild modules when module linker scripts are updated - split the module final link stage into scripts/Makefile.modfinal - fix the missed error code in merge_config.sh - improve the error message displayed on the attempt of the O= build in unclean source tree - remove 'clean-dirs' syntax - disable -Wimplicit-fallthrough warning for Clang - add CONFIG_CC_OPTIMIZE_FOR_SIZE_O3 for ARC - remove ARCH_{CPP,A,C}FLAGS variables - add $(BASH) to run bash scripts - change *CFLAGS_.o to take the relative path to $(obj) instead of the basename - stop suppressing Clang's -Wunused-function warnings when W=1 - fix linux/export.h to avoid genksyms calculating CRC of trimmed exported symbols - misc cleanups * tag 'kbuild-v5.4' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild: (63 commits) genksyms: convert to SPDX License Identifier for lex.l and parse.y modpost: use __section in the output to *.mod.c modpost: use MODULE_INFO() for __module_depends export.h, genksyms: do not make genksyms calculate CRC of trimmed symbols export.h: remove defined(__KERNEL__), which is no longer needed kbuild: allow Clang to find unused static inline functions for W=1 build kbuild: rename KBUILD_ENABLE_EXTRA_GCC_CHECKS to KBUILD_EXTRA_WARN kbuild: refactor scripts/Makefile.extrawarn merge_config.sh: ignore unwanted grep errors kbuild: change *FLAGS_.o to take the path relative to $(obj) modpost: add NOFAIL to strndup modpost: add guid_t type definition kbuild: add $(BASH) to run scripts with bash-extension kbuild: remove ARCH_{CPP,A,C}FLAGS kbuild,arc: add CONFIG_CC_OPTIMIZE_FOR_PERFORMANCE_O3 for ARC kbuild: Do not enable -Wimplicit-fallthrough for clang for now kbuild: clean up subdir-ymn calculation in Makefile.clean kbuild: remove unneeded '+' marker from cmd_clean kbuild: remove clean-dirs syntax kbuild: check clean srctree even earlier ...

riscv: Add perf callchain support

This patch add support for perf callchain sampling on riscv platforms. The return address of leaf function is retrieved from pt_regs as it is not saved in the outmost frame.

Currently, the timestamp of module linker scripts are not checked. Add them to the dependency of modules so they are correctly rebuilt. Signed-off-by: Masahiro Yamada

riscv: drop unneeded -Wall addition

2019-07-17T01:25:10Z

The top level Makefile adds -Wall globally: KBUILD_CFLAGS := -Wall -Wundef -Werror=strict-prototypes -Wno-trigraphs \ For riscv, I see two "-Wall" added for compiling each object. Signed-off-by: Masahiro Yamada

kconfig: make arch/*/configs/defconfig the default of KBUILD_DEFCONFIG

2019-06-09T06:08:18Z

Until recently, if KBUILD_DEFCONFIG was not set by the arch Makefile, the default path arch/*/defconfig was used. The last users of the default are gone by the following commits: - Commit f3e20ad67b4c ("s390: move arch/s390/defconfig to arch/s390/configs/defconfig") - Commit 986a13769c4b ("alpha: move arch/alpha/defconfig to arch/alpha/configs/defconfig") Let's set arch/*/configs/defconfig as a new default. This saves KBUILD_DEFCONFIG for some architectures. Signed-off-by: Masahiro Yamada Acked-by: Catalin Marinas
