[PATCH OLK-6.6 v2 0/3] arm64: entry: Support hardware xint and xcall
by Jinjie Ruan 24 Mar '25

24 Mar '25

Support hardware xint and xcall. Changes in v2: - Reuse irq_is_nmi(). - Reuse the xint set and check logic in xint 1.0. - Introduce fast_handle_xint(). - Rename enable_xint_xcall() to enable_xfunc() and rename test_has_xint_xcall() to test_has_xfunc(). - Fix a typo. - Add a blank line after declarations. - Remove an excess semicolon.
