Hi @ldv-alt, I pushed a new HEAD with test for the new syscall and tested it with

  • x86_64 Alpine Linux
  • riscv64 Arch Linux, kernel 6.11.2 (riscv_hwprobe introduced)
  • riscv64 Arch Linux, kernel 6.1.80 (riscv_hwprobe not introduced)

Here's an example of tracing output:

$ ./strace --trace=riscv_hwprobe ~/hwprobe_dump/hwprobe >/dev/null
riscv_hwprobe([{key=RISCV_HWPROBE_KEY_IMA_EXT_0}], 1, 0, NULL, 0 <unfinished ...>
<... riscv_hwprobe resumed>[{key=RISCV_HWPROBE_KEY_IMA_EXT_0, value=RISCV_HWPROBE_IMA_FD|RISCV_HWPROBE_IMA_C|RISCV_HWPROBE_EXT_ZBA|RISCV_HWPROBE_EXT_ZBB|RISCV_HWPROBE_EXT_ZCA|RISCV_HWPROBE_EXT_ZCD}], 1, 0, NULL, 0) = 0
riscv_hwprobe([{key=RISCV_HWPROBE_KEY_HIGHEST_VIRT_ADDRESS}], 1, 0, NULL, 0 <unfinished ...>
<... riscv_hwprobe resumed>[{key=RISCV_HWPROBE_KEY_HIGHEST_VIRT_ADDRESS, value=0x4000000000}], 1, 0, NULL, 0) = 0
+++ exited with 0 +++

Thanks for your time and review.
