Since OA sseu config depends on engine class:instance, validate OA sseu config outside the switch. v2: (Ashutosh) - Clarify commit message - Use drm_dbg instead of DRM_DEBUG - Reorder stack variables Signed-off-by: Umesh Nerlige Ramappa Reviewed-by: Ashutosh Dixit --- drivers/gpu/drm/i915/i915_perf.c | 23 +++++++++++++---------- 1 file changed, 13 insertions(+), 10 deletions(-) diff --git a/drivers/gpu/drm/i915/i915_perf.c b/drivers/gpu/drm/i915/i915_perf.c index 283a4a3c6862..ebd76b5c9712 100644 --- a/drivers/gpu/drm/i915/i915_perf.c +++ b/drivers/gpu/drm/i915/i915_perf.c @@ -3940,7 +3940,9 @@ static int read_properties_unlocked(struct i915_perf *perf, u32 n_props, struct perf_open_properties *props) { + struct drm_i915_gem_context_param_sseu user_sseu; u64 __user *uprop = uprops; + bool config_sseu = false; u32 i; int ret; @@ -4069,8 +4071,6 @@ static int read_properties_unlocked(struct i915_perf *perf, props->hold_preemption = !!value; break; case DRM_I915_PERF_PROP_GLOBAL_SSEU: { - struct drm_i915_gem_context_param_sseu user_sseu; - if (GRAPHICS_VER_FULL(perf->i915) >= IP_VER(12, 50)) { drm_dbg(&perf->i915->drm, "SSEU config not supported on gfx %x\n", @@ -4085,14 +4085,7 @@ static int read_properties_unlocked(struct i915_perf *perf, "Unable to copy global sseu parameter\n"); return -EFAULT; } - - ret = get_sseu_config(&props->sseu, props->engine, &user_sseu); - if (ret) { - drm_dbg(&perf->i915->drm, - "Invalid SSEU configuration\n"); - return ret; - } - props->has_sseu = true; + config_sseu = true; break; } case DRM_I915_PERF_PROP_POLL_OA_PERIOD: @@ -4112,6 +4105,16 @@ static int read_properties_unlocked(struct i915_perf *perf, uprop += 2; } + if (config_sseu) { + ret = get_sseu_config(&props->sseu, props->engine, &user_sseu); + if (ret) { + drm_dbg(&perf->i915->drm, + "Invalid SSEU configuration\n"); + return ret; + } + props->has_sseu = true; + } + return 0; }
