Make the new ctx based implementation behave just like the old one. This means _including_ the yend row and xend column. This fixes the G-Watch and DigiClk not looking as they should.

Use ctx to display the panic message. The implementation contains a few safeguards to hopefully deal with any breakage that happended before the panic.

With the PMIC task calling graphics code, it now needs a bit more stack space. Increase the allocation to ensure we won't get a stack overflow here.

Instead of duplicating the drawing code in the personal state menu, reuse the method from the parent class. This reduces code duplication but most importantly means the personal state app can benefit from fixes in the "upstream" code. Concretely, due to the changes related to ctx, this fixes visual artifacts produced by the "custom" rendering code (black areas to the right of the text).

Replace the gfx-based implementations of the Epicardium display API calls with ctx-based ones that try to mimick the old behavior as much as possible. In the long run, these functions are just meant for backwards compatibility while new code should interface with ctx directly (once this becomes possible). The implementations in this changeset are closely based on pippin's original Pycardium display API reimplementation. Co-developed-by:

Adds the most basic ctx integration, by just initializing the context and nothing more.

From upstream commit 35100785e2c4 ("ctx: rasterizer, micro optimizations in rasterizer_fill_rect"). The integration is mostly a copy of pippin's original integration with the biggest change being the use of a monospace default font. This font is autogenerated from lib/ctx/fira-mono.ttf at build-time so it can be easily replaced with a different one (just overwrite said file). git-url: https://ctx.graphics/.git Co-developed-by:

Move display initialization from hardware_early_init() into the display module to keep it closer to related functionality.

Move the display API code into the display/ subdirectory as well.

To not try and replace the entire gfx stack at once, start by "splicing in" the new driver for the two to work alongside each other. Primarily the new driver takes control now and we reconfigure the orientation on the fly whenever the old driver wants to update the screen.

Currently we're still working with the reference driver from Waveshare. This driver seems hacked together and also does not really fit for what we're doing with the display. Even less so because it configures the display upside down. As a first step towards dropping this vendor library, introduce a reimplementation which is purpose built to our usecase. This new library configures the screen right side up natively but still allows to change to the legacy orientation on the fly to support the old codebase.

The loop condition in the epic_sleep based sleep could underflow if an interrupt introduced too much delay at the end.
-
schneider authored
The clock source of epicardium is not very stable and can drift multiple percent. This has an effect on epic_sleep() and can lead to sleeps which are longer than anticipated. With this change we slowly move towards our sleep goal using multiple calls. This is less efficient but leads to precise results.

This can be used by the second core to signal that the system can go to a light sleep to recuce power consumption.

This reduces the power consumption of the system by around .1 mA when the personal state is not active.
