2021-11-09MIPS: fix *-pkg builds for loongson2ef platformMasahiro Yamada
Since commit 805b2e1d427a ("kbuild: include Makefile.compiler only when compiler is needed"), package builds for the loongson2f platform fail. $ make ARCH=mips CROSS_COMPILE=mips64-linux- lemote2f_defconfig bindeb-pkg [ snip ] sh ./scripts/package/builddeb arch/mips/loongson2ef//Platform:36: *** only binutils >= 2.20.2 have needed option -mfix-loongson2f-nop.

Stop. In general, adding $(error ...) in the parse stage is troublesome, and it is pointless to check toolchains even if we are not building anything. Do not include Kbuild.platform in such cases.

2021-11-09MIPS: VDSO: remove -nostdlib compiler flagMasahiro Yamada
The -nostdlib option requests the compiler to not use the standard system startup files or libraries when linking. It is effective only when $(CC) is used as a linker driver. Since commit 2ff906994b6c ("MIPS: VDSO: Use $(LD) instead of $(CC) to link VDSO"), $(LD) is directly used, hence -nostdlib is unneeded.

2021-11-09mips: BCM63XX: ensure that CPU_SUPPORTS_32BIT_KERNEL is setRandy Dunlap
Several header files need info on CONFIG_32BIT or CONFIG_64BIT, but kconfig symbol BCM63XX does not provide that info. This leads to many build errors, e.g.: arch/mips/include/asm/page.h:196:13: error: use of undeclared identifier 'CAC_BASE' return x - PAGE_OFFSET + PHYS_OFFSET; arch/mips/include/asm/mach-generic/spaces.h:91:23: note: expanded from macro 'PAGE_OFFSET' #define PAGE_OFFSET (CAC_BASE + PHYS_OFFSET) arch/mips/include/asm/io.h:134:28: error: use of undeclared identifier 'CAC_BASE' return (void *)(address + PAGE_OFFSET - PHYS_OFFSET); arch/mips/include/asm/mach-generic/spaces.h:91:23: note: expanded from macro 'PAGE_OFFSET' #define PAGE_OFFSET (CAC_BASE + PHYS_OFFSET) arch/mips/include/asm/uaccess.h:82:10: error: use of undeclared identifier '__UA_LIMIT' return (__UA_LIMIT & (addr | (addr + size) | __ua_size(size))) == 0; Selecting the SYS_HAS_CPU_BMIPS* symbols causes SYS_HAS_CPU_BMIPS to be set, which then selects CPU_SUPPORT_32BIT_KERNEL, which causes CONFIG_32BIT to be set.

2021-11-09MIPS: Allow modules to set board_be_handlerFlorian Fainelli
After making the brcmstb_gisb driver modular with 707a4cdf86e5 ("bus: brcmstb_gisb: Allow building as module") Guenter reported that mips allmodconfig failed to link because board_be_handler was referenced. Thomas indicated that if we were to continue making the brcmstb_gisb driver modular for MIPS we would need to introduce a function that allows setting the board_be_handler and export that function towards modules. This is what is being done here: board_be_handler is made static and is now settable with a mips_set_be_handler() function which is exported.

2021-11-02mips: cm: Convert to bitfield API to fix out-of-bounds accessGeert Uytterhoeven
mips_cm_error_report() extracts the cause and other cause from the error register using shifts. This works fine for the former, as it is stored in the top bits, and the shift will thus remove all non-related bits. However, the latter is stored in the bottom bits, hence thus needs masking to get rid of non-related bits. Without such masking, using it as an index into the cm2_causes[] array will lead to an out-of-bounds access, probably causing a crash. Fix this by using FIELD_GET() instead. Bite the bullet and convert all MIPS CM handling to the bitfield API, to improve readability and safety.

2021-10-24MIPS: Fix assembly error from MIPSr2 code used within MIPS_ISA_ARCH_LEVELMaciej W. Rozycki
Fix assembly errors like: {standard input}: Assembler messages: {standard input}:287: Error: opcode not supported on this processor: mips3 (mips3) `dins $10,$7,32,32' {standard input}:680: Error: opcode not supported on this processor: mips3 (mips3) `dins $10,$7,32,32' {standard input}:1274: Error: opcode not supported on this processor: mips3 (mips3) `dins $12,$9,32,32' {standard input}:2175: Error: opcode not supported on this processor: mips3 (mips3) `dins $10,$7,32,32' make[1]: *** [scripts/Makefile.build:277: mm/highmem.o] Error 1 with code produced from `__cmpxchg64' for MIPS64r2 CPU configurations using CONFIG_32BIT and CONFIG_PHYS_ADDR_T_64BIT. This is due to MIPS_ISA_ARCH_LEVEL downgrading the assembly architecture to `r4000' i.e. MIPS III for MIPS64r2 configurations, while there is a block of code containing a DINS MIPS64r2 instruction conditionalized on MIPS_ISA_REV >= 2 within the scope of the downgrade. The assembly architecture override code pattern has been put there for LL/SC instructions, so that code compiles for configurations that select a processor to build for that does not support these instructions while still providing run-time support for processors that do, dynamically switched by non-constant `cpu_has_llsc'. It went in with linux-mips.org commit aac8aa7717a2 ("Enable a suitable ISA for the assembler around ll/sc so that code builds even for processors that don't support the instructions. Plus minor formatting fixes.") back in 2005. Fix the problem by wrapping these instructions along with the adjacent SYNC instructions only, following the practice established with commit cfd54de3b0e4 ("MIPS: Avoid move psuedo-instruction whilst using MIPS_ISA_LEVEL") and commit 378ed6f0e3c5 ("MIPS: Avoid using .set mips0 to restore ISA"). Strictly speaking the SYNC instructions do not have to be wrapped as they are only used as a Loongson3 erratum workaround, so they will be enabled in the assembler by default, but do this so as to keep code consistent with other places.

2021-09-11perf tools: Allow build-id with trailing zerosNamhyung Kim
Currently perf saves a build-id with size but old versions assumes the size of 20. In case the build-id is less than 20 (like for MD5), it'd fill the rest with 0s. I saw a problem when old version of perf record saved a binary in the build-id cache and new version of perf reads the data. The symbols should be read from the build-id cache (as the path no longer has the same binary) but it failed due to mismatch in the build-id. symsrc__init: build id mismatch for /home/namhyung/.debug/.build-id/53/e4c2f42a4c61a2d632d92a72afa08f00000000/elf. The build-id event in the data has 20 byte build-ids, but it saw a different size (16) when it reads the build-id of the elf file in the build-id cache. $ readelf -n ~/.debug/.build-id/53/e4c2f42a4c61a2d632d92a72afa08f00000000/elf Displaying notes found in: .note.gnu.build-id Owner Data size Description GNU 0x00000010 NT_GNU_BUILD_ID (unique build ID bitstring) Build ID: 53e4c2f42a4c61a2d632d92a72afa08f Let's fix this by allowing trailing zeros if the size is different.

2021-09-11perf tools: Fix hybrid config terms list corruptionAdrian Hunter
