Subject: [kvm-unit-tests PATCH] riscv: sbi: Prepare for assembly entry points
Date: Wed,  6 Nov 2024 10:40:16 +0100	[thread overview]
Message-ID: <20241106094015.21204-2-andrew.jones@linux.dev> (raw)

From: James Raphael Tiovalen <jamestiotio@gmail.com>

The HSM tests will need to test HSM start and resumption from HSM
suspend. Prepare for these tests, as well other tests, such as the
SUSP resume tests, by providing an assembly file for SBI tests.
