[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [PATCH v4 2/2] docs: fusa: Add the requirements for some of the commands of XEN_VERSION
We have written the requirements for some of the commands of the XEN_VERSION hypercall. Signed-off-by: Ayan Kumar Halder <ayan.kumar.halder@xxxxxxx> --- Changes from - v1 - 1. Reworded the requirement so as to avoid mentioining variable names or hardcoded strings. Otherwise, one would need to change the requirement each time the code changes. v2 - 1. Moved few changes to previous patch. v3 - 1. Removed the internal implementation details from the design requirements so that they can be verified by black box tests. .../fusa/reqs/design-reqs/arm64/hypercall.rst | 15 ++++ .../design-reqs/arm64/version_hypercall.rst | 32 +++++++ .../reqs/design-reqs/version_hypercall.rst | 63 ++++++++++++++ docs/fusa/reqs/index.rst | 3 + docs/fusa/reqs/product-reqs/hypercall.rst | 20 +++++ .../reqs/product-reqs/version_hypercall.rst | 85 +++++++++++++++++++ 6 files changed, 218 insertions(+) create mode 100644 docs/fusa/reqs/design-reqs/arm64/version_hypercall.rst create mode 100644 docs/fusa/reqs/design-reqs/version_hypercall.rst create mode 100644 docs/fusa/reqs/product-reqs/hypercall.rst diff --git a/docs/fusa/reqs/design-reqs/arm64/hypercall.rst b/docs/fusa/reqs/design-reqs/arm64/hypercall.rst index 82ecf690a3..3b4af18323 100644 --- a/docs/fusa/reqs/design-reqs/arm64/hypercall.rst +++ b/docs/fusa/reqs/design-reqs/arm64/hypercall.rst @@ -58,3 +58,18 @@ Comments: Covers: - `XenProd~version_hyp_first_param~1` - `XenProd~version_hyp_second_param~1` + +Return value +------------ + +`XenSwdgn~arm64_ret_val~1` + +Description: +Xen shall store the return value in x0. + +Rationale: + +Comments: + +Covers: + - `XenProd~hyp_err_ret_val~1` diff --git a/docs/fusa/reqs/design-reqs/arm64/version_hypercall.rst b/docs/fusa/reqs/design-reqs/arm64/version_hypercall.rst new file mode 100644 index 0000000000..ccfcb35a7a --- /dev/null +++ b/docs/fusa/reqs/design-reqs/arm64/version_hypercall.rst @@ -0,0 +1,32 @@ +..
