Using that value as the original minimum prevents the later min_freq write from enabling the GuC ignore_efficient_freq parameter, so min_freq can keep moving toward RPe. Since RPe varies dynamically with thermal conditions, use RPn as the fixed minimum baseline instead. This ensures that writing to min_freq enables the ignore_efficient_freq GuC parameter. v2: Fix commit message (Vinay) v3: Cosmetic changes (Kamil) Closes:https://gitlab.freedesktop.org/drm/xe/kernel/issues/8344 Signed-off-by: Sk Anirban Reviewed-by: Vinay Belgaumkar --- tests/intel/xe_pmu.c | 8 ++------ 1 file changed, 2 insertions(+), 6 deletions(-) diff --git a/tests/intel/xe_pmu.c b/tests/intel/xe_pmu.c index fb4b871e7..4bbc801a1 100644 --- a/tests/intel/xe_pmu.c +++ b/tests/intel/xe_pmu.c @@ -903,10 +903,8 @@ static void test_gt_frequency(int fd, struct drm_xe_engine_class_instance *eci) unsigned long config_rq_freq, config_act_freq; double min[2], max[2]; uint32_t gt = eci->gt_id; - uint32_t orig_min = xe_gt_get_freq(fd, eci->gt_id, "min"); + uint32_t orig_min = xe_gt_get_freq(fd, eci->gt_id, "rpn"); uint32_t orig_max = xe_gt_get_freq(fd, eci->gt_id, "max"); - uint32_t current_min; - uint32_t orig_rpe; uint32_t vm; int pmu_fd[2]; @@ -956,9 +954,7 @@ static void test_gt_frequency(int fd, struct drm_xe_engine_class_instance *eci) * Restore min/max. */ igt_assert(xe_gt_set_freq(fd, gt, "min", orig_min) > 0); - orig_rpe = xe_gt_get_freq(fd, gt, "rpe"); - current_min = xe_gt_get_freq(fd, gt, "min"); - igt_assert(current_min == orig_min || current_min == orig_rpe); + igt_assert(xe_gt_get_freq(fd, gt, "min") == orig_min); igt_info("Minimum frequency: requested %.1f, actual %.1f\n", min[0], min[1]); -- 2.43.0
