[PATCH 00/19] riscv: Support vendor extensions and xtheadvector

by Charlie Jenkins

This patch series ended up much larger than expected, please bear with me! The goal here is to support vendor extensions, starting at probing the device tree and ending with reporting to userspace. The main design objective was to allow vendors to operate independently of each other. This has been achieved by delegating vendor extensions to a new struct "hart_isa_vendor" which is a counterpart to "hart_isa". Each vendor will have their own list of extensions they support. Each vendor will have a "namespace" to themselves which is set at the key values of 0x8000 - 0x8080. It is up to the vendor's disgression how they wish to allocate keys in the range for their vendor extensions. Reporting to userspace follows a similar story, leveraging the hwprobe syscall. There is a new hwprobe key RISCV_HWPROBE_KEY_VENDOR_EXT_0 that is used to request supported vendor extensions. The vendor extension keys are disambiguated by the vendor associated with the cpumask passed into hwprobe. The entire 64-bit key space is available to each vendor. On to the xtheadvector specific code. xtheadvector is a custom extension that is based upon riscv vector version 0.7.1 [1]. All of the vector routines have been modified to support this alternative vector version based upon whether xtheadvector was determined to be supported at boot. I have tested this with an Allwinner Nezha board. I ran into issues booting the board on 6.9-rc1 so I applied these patches to 6.8. There are a couple of minor merge conflicts that do arrise when doing that, so please let me know if you have been able to boot this board with a 6.9 kernel. I used SkiffOS [2] to manage building the image, but upgraded the U-Boot version to Samuel Holland's more up-to-date version [3] and changed out the device tree used by U-Boot with the device trees that are present in upstream linux and this series. Thank you Samuel for all of the work you did to make this task possible. To test the integration, I used the riscv vector kselftests. I modified the test cases to be able to more easily extend them, and then added a xtheadvector target that works by calling hwprobe and swapping out the vector asm if needed.

[PATCH] selftests/intel_pstate: Add validity check for cpu min/max frequency

If libcpupower is not properly installed somehow, the cpupower tool cannot work, and cpu min_freq and max_freq are not correctly assigned, but the code can still keep going and gives an "ok" result at last, which seems not to be the expected behavior of this test. tools/testing/selftests/intel_pstate# make run_tests TAP version 13 1..1 # selftests: intel_pstate: run.sh # cpupower: error while loading shared libraries: libcpupower.so.1: cannot open shared object file: No such file or directory # ./run.sh: line 90: / 1000: syntax error: operand expected (error token is "/ 1000") # cpupower: error while loading shared libraries: libcpupower.so.1: cannot open shared object file: No such file or directory # ./run.sh: line 92: / 1000: syntax error: operand expected (error token is "/ 1000") # ======================================================================== # The marketing frequency of the cpu is 3400 MHz # The maximum frequency of the cpu is MHz # The minimum frequency of the cpu is MHz # Target Actual Difference MSR(0x199) max_perf_pct ok 1 selftests: intel_pstate: run.sh Fix this by adding null checks as well as [ $var -eq $var ] checks to confirm that both min_freq and max_freq are valid integers.

[PATCH 0/4] A new selftests/ directory for arm compatibility testing

by Dev Jain

This series introduces the selftests/arm directory, which tests 32 and 64-bit kernel compatibility with 32-bit ELFs running on the Aarch platform. The need for this bucket of tests is that 32 bit applications built on legacy ARM architecture must not break on the new Aarch64 platforms and the 64-bit kernel. The kernel must emulate the data structures, system calls and the registers according to Aarch32, when running a 32-bit process; this directory fills that testing requirement. One may find similarity between this directory and selftests/arm64; it is advisable to refer to that since a lot has been copied from there itself. The mm directory includes a test for checking 4GB limit of the virtual address space of a process. The signal directory contains two tests, following a common theme: mangle with arm_cpsr, dumped by the kernel to user space while invoking the signal handler; kernel must spot this illegal attempt and terminate the program by SEGV. The elf directory includes a test for checking the 32-bit status of the ELF. The series has been tested on 6.9.0-rc2, on Aarch64 platform. Testing remains to be done on Aaarch32.
