[kvm-unit-tests PATCH v4 0/3] riscv: sbi: Add support to test HSM extension

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This patch series adds support for testing all 4 functions of the HSM
extension as defined in the RISC-V SBI specification. The first 2
patches adds some helper routines to prepare for the HSM test, while
the third patch adds the actual test for the HSM extension.

v4:
- Addressed all of Andrew's comments.
- Included the 2 patches from Andrew's branch that refactored some
  functions.
- Added timers to all of the waiting activities in the HSM tests.

v3:
- Addressed all of Andrew's comments.
- Split the report_prefix_pop patch into its own series.
- Added a new environment variable to specify the maximum number of
  CPUs supported by the SBI implementation.

v2:
- Addressed all of Andrew's comments.
- Added a new patch to add helper routines to clear multiple prefixes.
- Reworked the approach to test the HSM extension by using cpumask and
  on-cpus.
