Subject: [PATCH V2 4/4] selftests/mm: skip virtual_address_range tests on riscv
Date: Tue, 8 Oct 2024 17:41:41 +0800 [thread overview]
Message-ID: <20241008094141.549248-5-zhangchunyan@iscas.ac.cn> (raw)
In-Reply-To: <20241008094141.549248-1-zhangchunyan@iscas.ac.cn>
RISC-V doesn't currently have the behavior of restricting the virtual
address space which virtual_address_range tests check, this will
cause the tests fail. So lets disable the whole test suite for riscv64
for now, not build it and run_vmtests.sh will skip it if it is not present.
