RPI 4 Model B only shows one DRM CRTC/Connector when two HDMI displays connected #919

Closed angusto closed 2 years ago

angusto commented 3 years ago

I am using gatesgarth branch meta-raspberrypi, and kernel is "Linux raspberrypi4-64 5.10.17-v8", when connecting two monitors(4k and 1080p) to the RPI 4 Model B two Micro HDMI ports, and the one HDMI port which near to USB Type-c power supply port can show the UI(GNOME-SHELL), the another one shows rainbow. after checking the DRM debug FS of kernel, find there is only one CRTC/Connector in DRM card0(vc4 Node), below is the details:

so want to confirm here: if Linux DRM vc4 driver(not sure why CPU is still bcm2835? should be bcm2711?) only support one HDMI port connected at the same time? i have no DSI display in hands now, not sure if is can support two CRTC/conntector when connecting one HDMI port and one DSI port at the same time? or any config can enable two HDMIs CRTC/Connector? thank you

Did some checks and found the num_displays from firmware is always 1:

rpi_firmware_property(vc4->firmware,
                                    RPI_FIRMWARE_FRAMEBUFFER_GET_NUM_DISPLAYS,
                                    &num_displays, sizeof(u32));

maybe caused by the wrong firmware, anyone met the similar issue?

Have you tried to reproduce on the current HEAD of master?
