I can see that vb2-vmalloc would call vmalloc_user() which does zero the allocated memory: https://elixir.bootlin.com/linux/v5.10.9/source/mm/vmalloc.c#L2661 Best regards, Tomasz > > Signed-off-by: Heiko Stuebner <heiko.stuebner@theobroma-systems.com> > Signed-off-by: Dafna Hirschfeld <dafna.hirschfeld@collabora.com> > Reviewed-by: Ezequiel Garcia <ezequiel@collabora.com> > Acked-by: Helen Koike <helen.koike@collabora.com> > --- > .../platform/rockchip/rkisp1/rkisp1-params.c | 2 +- > .../platform/rockchip/rkisp1/rkisp1-stats.c | 12 +++- > include/uapi/linux/rkisp1-config.h | 66 ++++++++++++++++--- > 3 files changed, 67 insertions(+), 13 deletions(-) > > diff --git a/drivers/media/platform/rockchip/rkisp1/rkisp1-params.c b/drivers/media/platform/rockchip/rkisp1/rkisp1-params.c > index 021939466b24..aa5f45749543 100644 > --- a/drivers/media/platform/rockchip/rkisp1/rkisp1-params.c > +++ b/drivers/media/platform/rockchip/rkisp1/rkisp1-params.c > @@ -391,7 +391,7 @@ static void rkisp1_goc_config(struct rkisp1_params *params, > RKISP1_CIF_ISP_CTRL_ISP_GAMMA_OUT_ENA);
