2022-05-26drm/amd/display: add Coverage blend mode for overlay planeSung Joon Kim1-5/+12
According to the KMS man page, there is a "Coverage" alpha blend mode that assumes the pixel color values have NOT been pre-multiplied and will be done when the actual blending to the background color values happens. Previously, this mode hasn't been enabled in our driver and it was assumed that all normal overlay planes are pre-multiplied by default. When a 3rd party app is used to input a image in a specific format, e.g. PNG, as a source of a overlay plane to blend with the background primary plane, the pixel color values are not pre-multiplied. So by adding "Coverage" blend mode, our driver will support those cases. Issue fixed: Overlay plane alpha channel blending is incorrect Issue tracker: https://gitlab.freedesktop.org/drm/amd/-/issues/1769 Reference: https://dri.freedesktop.org/docs/drm/gpu/drm-kms.html#plane-composition-properties Adding Coverage support also enables IGT kms_plane_alpha_blend Coverage subtests: 1. coverage-7efc 2. coverage-vs-premult-vs-constant Changes 1. Add DRM_MODE_BLEND_COVERAGE blend mode capability 2. Add "pre_multiplied_alpha" flag for Coverage case 3. Read the correct flag and set the DCN MPCC pre_multiplied register bit (only on overlay plane) Bug: https://gitlab.freedesktop.org/drm/amd/-/issues/1769 Signed-off-by: Sung Joon Kim <Sungjoon.Kim@amd.com> Reviewed-by: Melissa Wen <mwen@igalia.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2022-05-23drm/amd/display: Move connector debugfs to drmBhanuprakash Modem3-31/+13
As drm_connector already have the display_info, instead of creating "output_bpc" debugfs in vendor specific driver, move the logic to the drm layer. This patch will also move "Current" bpc to the crtc debugfs from connector debugfs, since we are getting this info from crtc_state.

Move DRM's HMDI helpers into the display/ subdirectoy and add it to DRM's display helpers. Update all affected drivers. No functional changes. The HDMI helpers were implemented in the EDID and connector code, but are actually unrelated. With the move to the display-helper library, we can remove the dependency on drm_edid.{c,h} in some driver's HDMI source files. Several of the HDMI helpers remain in EDID code because both share parts of their implementation internally. With better refractoring of the EDID code, those HDMI helpers could be moved into the display-helper library as well. v3: * fix Kconfig dependencies (Javier) v2: * reduce HDMI helpers to avoid exporting functions (Jani) * fix include statements (Jani, Javier) * update Kconfig symbols Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Javier Martinez Canillas <javierm@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20220421073108.19226-8-tzimmermann@suse.de

2022-03-15drm/amdgpu: Use drm_mode_copy()Ville Syrjälä1-3/+3
struct drm_display_mode embeds a list head, so overwriting the full struct with another one will corrupt the list (if the destination mode is on a list). Use drm_mode_copy() instead which explicitly preserves the list head of the destination mode. Even if we know the destination mode is not on any list using drm_mode_copy() seems decent as it sets a good example. Bad examples of not using it might eventually get copied into code where preserving the list head actually matters. Obviously one case not covered here is when the mode itself is embedded in a larger structure and the whole structure is copied. But if we are careful when copying into modes embedded in structures I think we can be a little more reassured that bogus list heads haven't been propagated in. @is_mode_copy@ @@ drm_mode_copy(...) { ... } @depends on !is_mode_copy@ struct drm_display_mode *mode; expression E, S; @@ ( - *mode = E + drm_mode_copy(mode, &E) | - memcpy(mode, E, S) + drm_mode_copy(mode, E) ) @depends on !is_mode_copy@ struct drm_display_mode mode; expression E; @@ ( - mode = E + drm_mode_copy(&mode, &E) | - memcpy(&mode, E, S) + drm_mode_copy(&mode, E) ) @@ struct drm_display_mode *mode; @@ - &*mode + mode Cc: Alex Deucher <alexander.deucher@amd.com> Cc: Harry Wentland <harry.wentland@amd.com> Cc: Leo Li <sunpeng.li@amd.com> Cc: Rodrigo Siqueira <Rodrigo.Siqueira@amd.com> Cc: amd-gfx@lists.freedesktop.org Reviewed-by: Harry Wentland <harry.wentland@amd.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2022-03-15drm/amd/display: Fix double free during GPU reset on DC streamsNicholas Kazlauskas1-3/+6
[Why] The issue only occurs during the GPU reset code path. We first backup the current state prior to commiting 0 streams internally from DM to DC. This state backup contains valid link encoder assignments. DC will clear the link encoder assignments as part of current state (but not the backup, since it was a copied before the commit) and free the extra stream reference it held. DC requires that the link encoder assignments remain cleared/invalid prior to commiting. Since the backup still has valid assignments we call the interface post reset to clear them. This routine also releases the extra reference that the link encoder interface held - resulting in a double free (and eventually a NULL pointer dereference). [How] We'll have to do a full DC commit anyway after GPU reset because the stream count previously went to 0. We don't need to retain the assignment that we had backed up, so just copy off of the now clean current state assignment after the reset has occcurred with the new link_enc_cfg_copy() interface.

2022-02-23drm/amd/display: clear remote dc_sink when stop mstWayne Lin1-1/+19
[Why] Currently, we don't have code path to release remote dc_sink when unplug MST hub from the system. After few times hotplug, we hit the limition of maximum number of remote dc_sink and can't light up new connected monitor anymore. [How] Releasing all remote dc_sink at dm_helpers_dp_mst_stop_top_mgr() was removed by previous patch. Restore it.

[Why] When display topology changed on DSC hub we add all crtcs with dsc support to atomic state. Refer to patch:"drm/amd/display: Trigger modesets on MST DSC connectors" However the original implementation may skip crtc if the topology change caused by unplug. That potentially could lead to no-lightup or corruption on DSC hub after unplug event on one of the connectors.

2022-02-07drm/amd/display: Cap pflip irqs per max otg numberRoman Li1-1/+1
[Why] pflip interrupt order are mapped 1 to 1 to otg id. e.g. if irq_src=26 corresponds to otg0 then 27->otg1, 28->otg2... Linux DM registers pflip interrupts per number of crtcs. In fused pipe case crtc numbers can be less than otg id. e.g. if one pipe out of 3(otg#0-2) is fused adev->mode_info.num_crtc=2 so DM only registers irq_src 26,27. This is a bug since if pipe#2 remains unfused DM never gets otg2 pflip interrupt (irq_src=28) That may results in gfx failure due to pflip timeout.
