Add two more parameters to set spm_addr_dev0 & spm_addr_dev1 addresses. These two parameters configure the start SP addresses for each device in test_hmm driver. Consequently, this configures zone device type as coherent. Signed-off-by: Alex Sierra <alex.sierra@amd.com> --- v2: Add more mknods for device coherent type. These are represented under /dev/hmm_mirror2 and /dev/hmm_mirror3, only in case they have created at probing the hmm-test driver. --- tools/testing/selftests/vm/test_hmm.sh | 24 +++++++++++++++++++++--- 1 file changed, 21 insertions(+), 3 deletions(-)
