2024-07-09cpufreq: Add Loongson-3 CPUFreq driver supportHuacai Chen4-0/+409
Some of LoongArch processors (Loongson-3 series) support DVFS, their IOCSR.FEATURES has IOCSRF_FREQSCALE set. And they has a micro-core in the package called SMC (System Management Controller), which can be used to detect temperature, control fans, scale frequency and voltage, etc. The Loongson-3 CPUFreq driver is very simple now, it communicate with SMC, get DVFS info, set target frequency from CPUFreq core, and so on. There is a command list to interact with SMC, widely-used commands in the CPUFreq driver include: CMD_GET_VERSION: Get SMC firmware version. CMD_GET_FEATURE: Get enabled SMC features. CMD_SET_FEATURE: Enable SMC features, such as basic DVFS, BOOST. CMD_GET_FREQ_LEVEL_NUM: Get the number of all frequency levels. CMD_GET_FREQ_BOOST_LEVEL: Get the first boost frequency level. CMD_GET_FREQ_LEVEL_INFO: Get the detail info of a frequency level. CMD_GET_FREQ_INFO: Get the current frequency. CMD_SET_FREQ_INFO: Set the target frequency.

Fix it and observe that it is not necessary to sort the lists in different orders.

2024-07-06selftests/powerpc: Fix build with USERCFLAGS setMichael Ellerman1-4/+1
Currently building the powerpc selftests with USERCFLAGS set to anything causes the build to break: $ make -C tools/testing/selftests/powerpc V=1 USERCFLAGS=-Wno-error ... gcc -Wno-error cache_shape.c ... cache_shape.c:18:10: fatal error: utils.h: No such file or directory 18 | #include "utils.h" | ^~~~~~~~~ compilation terminated. This happens because the USERCFLAGS are added to CFLAGS in lib.mk, which causes the check of CFLAGS in powerpc/flags.mk to skip setting CFLAGS at all, resulting in none of the usual CFLAGS being passed. That can be seen in the output above, the only flag passed to the compiler is -Wno-error. Fix it by dropping the conditional setting of CFLAGS in flags.mk. Instead always set CFLAGS, but also append USERCFLAGS if they are set. Note that appending to CFLAGS (with +=) wouldn't work, because flags.mk is included by multiple Makefiles (to support partial builds), causing CFLAGS to be appended to multiple times. Additionally that would place the USERCFLAGS prior to the standard CFLAGS, meaning the USERCFLAGS couldn't override the standard flags. Being able to override the standard flags is desirable, for example for adding -Wno-error. With the fix in place, the CFLAGS are set correctly, including the USERCFLAGS: $ make -C tools/testing/selftests/powerpc V=1 USERCFLAGS=-Wno-error ... gcc -std=gnu99 -O2 -Wall -Werror -DGIT_VERSION='"v6.10-rc2-7-gdea17e7e56c3"' -I/home/michael/linux/tools/testing/selftests/powerpc/include -Wno-error cache_shape.c ...

2024-07-05selftests/vDSO: remove duplicate compiler invocations from MakefileJohn Hubbard1-9/+5
The Makefile open-codes compiler invocations that ../lib.mk already provides. Avoid this by using a Make feature that allows setting per-target variables, which in this case are: CFLAGS and LDFLAGS. This approach generates the exact same compiler invocations as before, but removes all of the code duplication, along with the quirky mangled variable names. So now the Makefile is smaller, less unusual, and easier to read. The new dependencies are listed after including lib.mk, in order to let lib.mk provide the first target ("all:"), and are grouped together with their respective source file dependencies, for visual clarity.

2024-07-05selftests/vDSO: remove partially duplicated "all:" target in MakefileJohn Hubbard1-8/+7
There were a couple of errors here: 1. TEST_GEN_PROGS was incorrectly prepending $(OUTPUT) to each program to be built. However, lib.mk already does that because it assumes "bare" program names are passed in, so this ended up creating $(OUTPUT)/$(OUTPUT)/file.c, which of course won't work as intended. 2. lib.mk was included before TEST_GEN_PROGS was set, which led to lib.mk's "all:" target not seeing anything to rebuild. So nothing worked, which caused the author to force things by creating an "all:" target locally--while still including ../lib.mk. Fix all of this by including ../lib.mk at the right place, and removing the $(OUTPUT) prefix to the programs to be built, and removing the duplicate "all:" target.

2024-07-05selftests/vDSO: fix clang build errors and warningsJohn Hubbard2-7/+27
When building with clang, via: make LLVM=1 -C tools/testing/selftests ...there are several warnings, and an error. This fixes all of those and allows these tests to run and pass. 1. Fix linker error (undefined reference to memcpy) by providing a local version of memcpy. 2. clang complains about using this form: if (g = h & 0xf0000000) ...so factor out the assignment into a separate step. 3. The code is passing a signed const char* to elf_hash(), which expects a const unsigned char *. There are several callers, so fix this at the source by allowing the function to accept a signed argument, and then converting to unsigned operations, once inside the function. 4. clang doesn't have __attribute__((externally_visible)) and generates a warning to that effect. Fortunately, gcc 12 and gcc 13 do not seem to require that attribute in order to build, run and pass tests here, so remove it.
