X-BeenThere: intel-gfx@lists.freedesktop.org X-Mailman-Version: 2.1.29 Precedence: list List-Id: Intel graphics driver community testing & development List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Errors-To: intel-gfx-bounces@lists.freedesktop.org Sender: "Intel-gfx" From: Maarten Lankhorst Make vdsc work when no output is enabled. The big joiner needs VDSC on the slave, so enable it and set the appropriate bits. Also update timestamping constants, because slave crtc's are not updated in drm_atomic_helper_update_legacy_modeset_state(). This should be enough to bring up CRTC's in a big joiner configuration, without any plane configuration on the second pipe yet. HOWEVER, we still bring up the crtc's in the wrong order. We need to make sure that the master crtc is brought up after the slave crtc. This is done correctly later in this series. The next steps are to enable planes correctly, and make sure we enable and update both master and slave in the correct order. v2: * Manual rebase (Manasi) v3: * Rebase (Manasi) v4: * Rebase (Manasi) v5: * Get dsc power domain in ddi_init (Manasi) v6: * Remove dsc power put from dsc_disable (Maarten) v7: * Rebase (Manasi) v8: * Rebase (Manasi) v9: * Rebase (Manasi) Signed-off-by: Maarten Lankhorst Signed-off-by: Manasi Navare --- drivers/gpu/drm/i915/display/icl_dsi.c | 2 - drivers/gpu/drm/i915/display/intel_ddi.c | 68 ++- drivers/gpu/drm/i915/display/intel_display.c | 392 ++++++++++++------ .../drm/i915/display/intel_display_types.h | 1 + drivers/gpu/drm/i915/display/intel_dp.c | 6 +- drivers/gpu/drm/i915/display/intel_vdsc.c | 201 ++++----- drivers/gpu/drm/i915/display/intel_vdsc.h | 7 +- 7 files changed, 421 insertions(+), 256 deletions(-) diff --git a/drivers/gpu/drm/i915/display/icl_dsi.c b/drivers/gpu/drm/i915/display/icl_dsi.c index 4400e83f783f..be8756816650 100644 --- a/drivers/gpu/drm/i915/display/icl_dsi.c +++ b/drivers/gpu/drm/i915/display/icl_dsi.c @@ -1492,8 +1492,6 @@ static void gen11_dsi_get_config(struct intel_encoder *encoder, struct intel_crtc *crtc = to_intel_crtc(pipe_config->uapi.crtc);
