Review Comment:
I am not sure if this is a valid argument.
As an example, most of the Kconfig options from the ESP32 family of chips are similar to ESP-IDF's, which also use whitespaces for indentation instead of tabs. Yet, the Kconfig files follow the NuttX style.

Review Comment:
Taking it to an extreme scenario, suppose that for every third-party project to be included in `apps` that also uses Kconfig, each one follows a different formatting style.
Can you imagine the mess that the nuttx-apps repository would become?
So I am in favor of creating no exceptions to this.
Copying the options is already a huge benefit. Adapting to NuttX formatting is a small price to pay for consistency.

Hi @FASTSHIFT thanks for adding LVGL 8 support! I have a question: Should we insert `lv_tick_inc()` into the LVGL Task Loop, like this?
From [lvgldemo.c](https://github.com/apache/nuttx-apps/blob/master/examples/lvgldemo/lvgldemo.c#L213-L227):
```c
/* Handle LVGL tasks */
while (1)
{
uint32_t idle;
idle = lv_timer_handler();
/* Minimum sleep of 1ms */
idle = idle ? idle : 1;
usleep(idle * 1000);
// Inserted this: Increment LVGL Tick Count by 1 millisecond
lv_tick_inc(1);
}
```
__Before Adding `lv_tick_inc()`__: When we run `lvgldemo` on PINE64 PinePhone, the app doesn't read touch input from `/dev/input0`.
Also the LVGL Log shows: `It seems lv_tick_inc() is not called`
__After Adding `lv_tick_inc()`__: `lvgldemo` on PinePhone correctly handles the touch input. [(See this)](https://www.youtube.com/shorts/xE9U5IQPmlg)
I'm not sure if my parameter to `lv_tick_inc()` is correct. Maybe we need to compute the actual elapsed milliseconds using the System Timer? This might help to reduce the lag that we see in the [demo video](https://www.youtube.com/shorts/xE9U5IQPmlg).
Thanks for looking into this :-)

Prevent failure when executing `tools/configure.sh`. If the user needs to modify the lvgl version, keeping the original format is conducive to file comparison.

Review Comment:
Actually, the `ttgo_t_display_esp32:lvgl_fb` shows exactly this warning. I couldn't understand this implementation of the double buffer functionality. Do you check if there is a second "virtual" framebuffer device to use as a second buffer for the actual display? I don't recall any application that registers two framebuffers on such scheme... Could you please double-check this implementation?

Review Comment:
I'm still getting this warning using the `ttgo_t_display_esp32:lvgl_fb`. I couldn't figure out the implementation, but I'd say to double-check the examples that use framebuffer.
```

@FASTSHIFT thank you so much! LVGL on PinePhone works great now, it feels very responsive: [Demo on YouTube](https://www.youtube.com/shorts/APge9bTt-ho)
[(Compare with the previous laggy demo)](https://www.youtube.com/shorts/xE9U5IQPmlg)
I have documented the settings here: ["LVGL Calls Our Driver"](https://lupyuen.github.io/articles/touch2#lvgl-calls-our-driver)
Thanks again! :-)

I have lowered this LOG level to INFO level and can ignore this warning. lv_port_fbdev will continue to use the traditional single frame framebuffer logic.

Review Comment:
There are two ways to allocate double-frame framebuffers, one is traditional two-frame buffers next to consecutive addresses, relying on `pinfo.yoffset` to switch the buffer to be displayed. However, on embedded devices, the size of a single block of SRAM may be limited and cannot accommodate two frames of buffers with consecutive addresses. It is necessary to place the two buffers on two discontinuous addresses. Here we use the method of the `fbdev_try_init_fbmem2` function, which will Re-acquire the address of the second buffer from the driver, so that the logic of the switch buffer (by setting `pinfo.yoffset`) can be shared perfectly. (this solution comes from @xiaoxiang781216 )

Review Comment:

I have lowered this LOG level to INFO level and can ignore this warning. lvgl will continue to use the traditional single frame framebuffer logic.

I have lowered this LOG level to INFO level and can ignore this warning.
