From: Jouni Högander Date: Mon, 30 Jan 2023 08:06:51 +0000 (+0200) Subject: drm/i915/psr: Split sel fetch plane configuration into arm and noarm X-Git-Tag: Ubuntu-6.5.0-9.9~2862^2~24^2~143 X-Git-Url: https://git.proxmox.com/?a=commitdiff_plain;h=c22cf04c6ab1d9ad5be2ec36e9822bc45526e8ca;p=mirror_ubuntu-kernels.git drm/i915/psr: Split sel fetch plane configuration into arm and noarm SEL_FETCH_CTL registers are armed immediately when plane is disabled. SEL_FETCH_* instances of plane configuration are used when doing selective update and normal plane register instances for full updates. Currently all SEL_FETCH_* registers are written as a part of noarm plane configuration. If noarm and arm plane configuration are not happening within same vblank we may end up having plane as a part of selective update before it's PLANE_SURF register is written. Fix this by splitting plane selective fetch configuration into arm and noarm versions and call them accordingly. Write SEL_FETCH_CTL in arm version. v3: - add arm suffix into intel_psr2_disable_plane_sel_fetch v2: - drop color_plane parameter from arm part - dev_priv -> i915 in arm part Cc: Ville Syrjälä Cc: José Roberto de Souza Cc: Mika Kahola Cc: Vinod Govindapillai Cc: Stanislav Lisovskiy Cc: Luca Coelho Signed-off-by: Jouni Högander Reviewed-by: José Roberto de Souza Reviewed-by: Luca Coelho Link: https://patchwork.freedesktop.org/patch/msgid/20230130080651.3796929-1-jouni.hogander@intel.com --- diff --git a/drivers/gpu/drm/i915/display/intel_cursor.c b/drivers/gpu/drm/i915/display/intel_cursor.c index d190fa0d393b..c3173c0c2068 100644 --- a/drivers/gpu/drm/i915/display/intel_cursor.c +++ b/drivers/gpu/drm/i915/display/intel_cursor.c @@ -532,9 +532,10 @@ static void i9xx_cursor_update_arm(struct intel_plane *plane, skl_write_cursor_wm(plane, crtc_state);
