transfer interrupt wait timeout on new DSI Panel #133

Open jwaani2 opened 6 years ago

jwaani2 commented 6 years ago

Hello Mr Eric, I've seen your blogs and project recently. It's very helpful to me, so I want to pay my tribute of praise for your works in first. ^^b And I really appreciate of it.

I am working on new MIPI-DSI Panel, Innolux's product which named P101DBZ-3Z1, to attach on rpi cm3 with VC4 & KMS.

As I mentioned on title, I'm stuck at transfer timeout of "vc4 dsi" I adapted raydium-rm68200 to innolux, p101dbz, change match table, reset timing, init sequences but without changing filename. I traced into source code and I found that IRQ(vc4_dsi_irq_defer_to_thread_handler & vc4_dsi_irq_handler on drivers/gpu/drm/vc4/vc4_dsi.c) is not called.

I've working on it for weeks but I can not find the reason, could you please give me a tip? Thanks for your efforts again.

Do you have ignore_lcd=1 in /boot/config.txt? If not, the firmware might steal interrupts before linux gets them.

jwaani2 commented 6 years ago

Thank you for your advice. Sadly I already using ignore_lcd=1 on config.txt, but IRQ does not came up. In fact I am not familiar device tree. So I'm suspecting it as a device tree problem.

I add this to bcm283x.dtsi vc4_dsi: vc4_dsi { compatible = "innolux,p101dbz-3z1", "innolux,p101dbz";

address-cells = <1>;

                    #size-cells = <0>;
                    panel@0 {
                            compatible = "vc4-dsi", "vc4_dsi", "vc4 dsi";
                            reg = <0>;
                            port {
                                    panel_dsi_port: endpoint {
                                            remote-endpoint = <&dsi_out_port>;
                                    };
                            };
                    };
            };

This to dsi1 section port { dsi_out_port: endpoint { remote-endpoint = <&panel_dsi_port>; }; };

And change vc4-kms-v3d-overlay.dts like this... fragment@15 { target = <&dsi1>; overlay {

address-cells = <1>;

                    #size-cells = <0>;
                    status = "okay";

                    pitouchscreen: panel@0 {
                            compatible = "innolux,p101dbz-3z1", "innolux,p101dbz", "raspberrypi, touchscreen";
                            reg = <0>;
                            reset-gpios = <&gpio 26 GPIO_ACTIVE_LOW>;
                            vc4_dsi = <&vc4_dsi>;

                    };
            };
    };

Please take a look these. I would be really happy if you give me some more advice. Thanks.

Hi jwaani2,

I am doing the same thing like you, and got identical error logs. It seems panel initial command can't be sent. Try to call drm_panel_prepare() after the clock is ready in the end of vc4_dsi_encoder_enable() it works for me, and you can get vc4_dsi_irq_handler() triggered.

give a try and good luck!

jwaani2 commented 6 years ago

Hi EricBHLin,

Thank you very very much for your help. You were right! Now I got a IRQ triggered, after I follow your advice.

But still! there are timeouts at sending initial command. And those timeout error's counts are changing from 1 to dozens when I reboot my board. So I am checking the setting in vc4_dsi_encoder_enable().

Does anyone have any data for BCM2835 DSI controller's register like DSI1_HS_CLT0 ... DSI1_PHYC? I could not find datasheet for them. The only one that I have found is this link. https://elinux.org/BCM2835_registers

Please somebody help me~ T.T

Hi jwaani2,

I can't send my initial sequence completely,too. In my case, if the parameters in the initial commands are over 16, it will easily got these timeout errors. But if I am lucky enough, sometime the mipi transferring can be done...(still wondering if there were hw issues)

Have you tried to read something back from the panel ? I think it's the easiest way to confirm DSI connection . Despite your initial commands are sent without timeout errors, it just means these data were correctly sent to the FIFO.

About the registers of DSI, it seems not exposed to the public Thank you.

Hi EricBHlin,

It's been a long time.

In my LCD panel, it works but there are time out errors and seems not normal. Some times the screen looks good, but others it's broken for so many kind of cases(stripes, blanking, swapped X or Y, inverted... and so on)

For your information, I think it's better to fix arm_freq on config.txt to using DSI settled. After I fixed the arm_freq to 600, that many error case are changed to predictable, so I could fix the problem to changing some of initial codes.

Then I finally got my LCD panel works good. Thank you so much~ :)

@jwaani2 Hi,I'm very excited and intresting about what you have done.I want to driver a 1 lane mipi-dsi display with pi.But i am really new at DT and linux driver.Can you give me some advice?Thanks!

Thank you for your advice. Sadly I already using ignore_lcd=1 on config.txt, but IRQ does not came up. In fact I am not familiar device tree. So I'm suspecting it as a device tree problem.

I add this to bcm283x.dtsi vc4_dsi: vc4_dsi { compatible = "innolux,p101dbz-3z1", "innolux,p101dbz";

address-cells = <1>;

size-cells = <0>;

panel@0 { compatible = "vc4-dsi", "vc4_dsi", "vc4 dsi"; reg = <0>; port { panel_dsi_port: endpoint { remote-endpoint = <&dsi_out_port>; }; }; }; };

This to dsi1 section port { dsi_out_port: endpoint { remote-endpoint = <&panel_dsi_port>; }; };

And change vc4-kms-v3d-overlay.dts like this... fragment@15 { target = <&dsi1>; overlay {

address-cells = <1>;

size-cells = <0>;

status = "okay";

                    pitouchscreen: panel@0 {
                            compatible = "innolux,p101dbz-3z1", "innolux,p101dbz", "raspberrypi, touchscreen";
                            reg = <0>;
                            reset-gpios = <&gpio 26 GPIO_ACTIVE_LOW>;
                            vc4_dsi = <&vc4_dsi>;

                    };
            };
    };

Please take a look these. I would be really happy if you give me some more advice. Thanks.

Hi jwaani2,

i am currently trying to enable this DSI interface in the CM3 as well, however, i am not sure how to change the 3 overlay file, bcm283x.dtsi, vc4-kms-v3d-overlay.dts, and the new innolux driver that you added (maybe call raydium_rm68200.dts). Can you share this 3 overlay files to help my understanding?

Hi,

Does anyone succeed with this?
