Subject: [PATCH 01/26] config/arm: check SVE CPU flag
|
|
|
|
If compiled with SVE feature (e.g. "-march=armv8.2-a+sve'), the binary
|
|
could not run on non-SVE platform else it will encounter illegal
|
|
instruction [1].
|
|
|
|
This patch fixes it by adding 'RTE_CPUFLAG_SVE' to compile_time_cpuflags,
|
|
so that rte_cpu_is_supported() will print meaningful log under above
|
|
situation.
