From df78f7f660cdd5974b68649a95dbb34da4d4dfa7 Mon Sep 17 00:00:00 2001 From: Lyude Paul Date: Wed, 17 Aug 2022 15:38:33 -0400 Subject: drm/display/dp_mst: Call them time slots, not VCPI slots MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit VCPI is only sort of the correct term here, originally the majority of this code simply referred to timeslots vaguely as "slots" - and since I started working on it and adding atomic functionality, the name "VCPI slots" has been used to represent time slots. Now that we actually have consistent access to the DisplayPort spec thanks to VESA, I now know this isn't actually the proper term - as the specification refers to these as time slots. Since we're trying to make this code as easy to figure out as possible, let's take this opportunity to correct this nomenclature and call them by their proper name - timeslots. Likewise, we rename various functions appropriately, along with replacing references in the kernel documentation and various debugging messages. It's important to note that this patch series leaves the legacy MST code untouched for the most part, which is fine since we'll be removing it soon anyhow. There should be no functional changes in this series. v2: * Add note that Wayne Lin from AMD suggested regarding slots being between the source DP Tx and the immediate downstream DP Rx Signed-off-by: Lyude Paul Cc: Wayne Lin Cc: Ville Syrjälä Cc: Fangzhi Zuo Cc: Jani Nikula Cc: Imre Deak Cc: Daniel Vetter Cc: Sean Paul Acked-by: Jani Nikula Link: https://patchwork.freedesktop.org/patch/msgid/20220817193847.557945-5-lyude@redhat.com --- drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c') diff --git a/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c b/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c index 85fdd6baf803..cd30b02af8ee 100644 --- a/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c +++ b/drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c @@ -6401,7 +6401,7 @@ static int dm_encoder_helper_atomic_check(struct drm_encoder *encoder, clock = adjusted_mode->clock; dm_new_connector_state->pbn = drm_dp_calc_pbn_mode(clock, bpp, false); } - dm_new_connector_state->vcpi_slots = drm_dp_atomic_find_vcpi_slots(state, + dm_new_connector_state->vcpi_slots = drm_dp_atomic_find_time_slots(state, mst_mgr, mst_port, dm_new_connector_state->pbn, -- cgit
