25fdd5933e4c0f Jeykumar Sankaran 2018-06-27 117 * encoders. Virtual encoder manages one "logical" display. Physical
25fdd5933e4c0f Jeykumar Sankaran 2018-06-27 118 * encoders manage one intf block, tied to a specific panel/sub-panel.
25fdd5933e4c0f Jeykumar Sankaran 2018-06-27 119 * Virtual encoder defers as much as possible to the physical encoders.
25fdd5933e4c0f Jeykumar Sankaran 2018-06-27 120 * Virtual encoder registers itself with the DRM Framework as the encoder.
25fdd5933e4c0f Jeykumar Sankaran 2018-06-27 121 * @base: drm_encoder base class for registration with DRM
585b3f9472eea8 Sean Paul 2018-11-16 122 * @enc_spinlock: Virtual-Encoder-Wide Spin Lock for IRQ purposes
fba7427eb59496 Sean Paul 2018-11-16 123 * @enabled: True if the encoder is active, protected by enc_lock
25fdd5933e4c0f Jeykumar Sankaran 2018-06-27 124 * @num_phys_encs: Actual number of physical encoders contained.
25fdd5933e4c0f Jeykumar Sankaran 2018-06-27 125 * @phys_encs: Container of physical encoders managed.
25fdd5933e4c0f Jeykumar Sankaran 2018-06-27 126 * @cur_master: Pointer to the current master in this mode. Optimization
25fdd5933e4c0f Jeykumar Sankaran 2018-06-27 127 * Only valid after enable. Cleared as disable.
cca5ff947c7c6e Lee Jones 2020-11-23 128 * @cur_slave: As above but for the slave encoder.
cca5ff947c7c6e Lee Jones 2020-11-23 129 * @hw_pp: Handle to the pingpong blocks used for the display. No.
25fdd5933e4c0f Jeykumar Sankaran 2018-06-27 130 * pingpong blocks can be different than num_phys_encs.
58dca981074948 Vinod Koul 2022-04-06 131 * @hw_dsc: Handle to the DSC blocks used for the display.
58dca981074948 Vinod Koul 2022-04-06 132 * @dsc_mask: Bitmask of used DSC blocks.
cca5ff947c7c6e Lee Jones 2020-11-23 133 * @intfs_swapped: Whether or not the phys_enc interfaces have been swapped
25fdd5933e4c0f Jeykumar Sankaran 2018-06-27 134 * for partial update right-only cases, such as pingpong
25fdd5933e4c0f Jeykumar Sankaran 2018-06-27 135 * split where virtual pingpong does not generate IRQs
e4914867ac99ca Sean Paul 2018-11-16 136 * @crtc: Pointer to the currently assigned crtc. Normally you
e4914867ac99ca Sean Paul 2018-11-16 137 * would use crtc->state->encoder_mask to determine the
e4914867ac99ca Sean Paul 2018-11-16 138 * link between encoder/crtc. However in this case we need
e4914867ac99ca Sean Paul 2018-11-16 139 * to track crtc in the disable() hook which is called
e4914867ac99ca Sean Paul 2018-11-16 140 * _after_ encoder_mask is cleared.
6b6921e5537d0f Dmitry Baryshkov 2022-02-17 141 * @connector: If a mode is set, cached pointer to the active connector
25fdd5933e4c0f Jeykumar Sankaran 2018-06-27 142 * @crtc_kickoff_cb: Callback into CRTC that will flush & start

25fdd5933e4c0f Jeykumar Sankaran 2018-06-27 148 * @frame_busy_mask: Bitmask tracking which phys_enc we are still
25fdd5933e4c0f Jeykumar Sankaran 2018-06-27 149 * busy processing current command.
25fdd5933e4c0f Jeykumar Sankaran 2018-06-27 150 * Bit0 = phys_encs[0] etc.
25fdd5933e4c0f Jeykumar Sankaran 2018-06-27 151 * @crtc_frame_event_cb: callback handler for frame event
