Need to initialize the mask to 0 on init, otherwise it keeps increasing. bug: https://bugzilla.kernel.org/show_bug.cgi?id=82581 v2: also fix cu count v3: split count fix into separate patch Signed-off-by: Alex Deucher Reviewed-by: Michel Dänzer Signed-off-by: Greg Kroah-Hartman --- drivers/gpu/drm/radeon/cik.c | 1 + drivers/gpu/drm/radeon/si.c | 1 + 2 files changed, 2 insertions(+) diff --git a/drivers/gpu/drm/radeon/cik.c b/drivers/gpu/drm/radeon/cik.c index a5ce5e6b2974..78b4a277083c 100644 --- a/drivers/gpu/drm/radeon/cik.c +++ b/drivers/gpu/drm/radeon/cik.c @@ -3449,6 +3449,7 @@ static void cik_gpu_init(struct radeon_device *rdev) rdev->config.cik.max_sh_per_se, rdev->config.cik.max_backends_per_se); + rdev->config.cik.active_cus = 0; for (i = 0; i < rdev->config.cik.max_shader_engines; i++) { for (j = 0; j < rdev->config.cik.max_sh_per_se; j++) { rdev->config.cik.active_cus += diff --git a/drivers/gpu/drm/radeon/si.c b/drivers/gpu/drm/radeon/si.c index 238ff9343c4b..6c17d3b0be8b 100644 --- a/drivers/gpu/drm/radeon/si.c +++ b/drivers/gpu/drm/radeon/si.c @@ -3099,6 +3099,7 @@ static void si_gpu_init(struct radeon_device *rdev) rdev->config.si.max_sh_per_se, rdev->config.si.max_cu_per_sh); + rdev->config.si.active_cus = 0; for (i = 0; i < rdev->config.si.max_shader_engines; i++) { for (j = 0; j < rdev->config.si.max_sh_per_se; j++) { rdev->config.si.active_cus +=
