v1/v2: There is only the first patch: RISC-V: Enable cbo.clean/flush in usermode, which mainly removes the enabling of cbo.inval in user mode.
v3: Add the functionality of Expose Zicbom and selftests for Zicbom.
v4: Modify the order of macros, The test_no_cbo_inval function is added separately.
v5:
- Modify the order of RISCV_HWPROBE_KEY_ZICBOM_BLOCK_SIZE in hwprobe.rst
- "TEST_NO_ZICBOINVAL" -> "TEST_NO_CBO_INVAL"

So a v6 needs to be sent with:
- the fix for hwprobe_ext0_has() reported by kernel test robot
- a rebase on top of 6.14 since patch 2 will conflict with
RISCV_HWPROBE_KEY_VENDOR_EXT_THEAD_0
Thank you for the reminder. In fact, version 6 was sent out almost a month ago. Reference: https://lore.kernel.org/lkml/20250124035959.45499-1-cuiyunhui@bytedance.com/
Do you think you can do that soon so that it gets merged in 6.15? The patchset received a lot of RB so it would be too bad to miss this release.
Thanks,
Alex
Thanks, Yunhui
