Constants

DRAWING_QUANT_BIT

xochitl tends to draw with these but there are many more

DRAWING_QUANT_BIT_2

DRAWING_QUANT_BIT_3

EPDC_FLAG_ENABLE_INVERSION

If no processing required, skip update processing No processing means:

EPDC_FLAG_FORCE_MONOCHROME

Enables PXP_LUT_BLACK_WHITE transform on the buffer

EPDC_FLAG_GROUP_UPDATE

EPDC_FLAG_TEST_COLLISION

An update won’t be merged upon a conflict in case of a collusion if either update has this flag set, unless they are identical regions (same y,x,h,w)

EPDC_FLAG_USE_ALT_BUFFER

This is basically double buffering. We give it the bitmap we want to update, it swaps them. However the bitmap needs to fall within the smem.

EPDC_FLAG_USE_CMAP

Enables PXP_USE_CMAP transform on the buffer

FBIOGET_FSCREENINFO

FBIOGET_VSCREENINFO

FBIOPAN_DISPLAY

FBIOPUT_VSCREENINFO

MXCFB_DISABLE_EPDC_ACCESS

MXCFB_ENABLE_EPDC_ACCESS

MXCFB_SEND_UPDATE

Should be 0x4048462e. This is not the ordinary value which is used in most software. Even the official toolchain(s). See: https://github.com/canselcik/libremarkable/wiki/Framebuffer-Overview

MXCFB_SET_AUTO_UPDATE_MODE

MXCFB_SET_UPDATE_SCHEME

MXCFB_WAIT_FOR_UPDATE_COMPLETE

Type Definitions

NativeWidthType

This is to allow tests to run on systems with 64bit pointer types. It doesn’t make a difference since we will be mocking the ioctl calls.
