* [build] Mark known reviewed files as permitted for UEFI Secure BootMichael Brown2026-01-141-0/+1
| | | | | | | | | Some past security reviews carried out for UEFI Secure Boot signing submissions have covered specific drivers or functional areas of iPXE. Mark all of the files comprising these areas as permitted for UEFI Secure Boot. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [fbcon] Remove userptr_t from framebuffer console driversMichael Brown2025-04-251-7/+6Star
| | | | | | | | | | | | Simplify the framebuffer console drivers by assuming that the raw framebuffer, character cell array, background picture, and glyph data are all directly accessible via pointer dereferences. In particular, this avoids the need to copy each glyph during drawing: the VESA framebuffer driver can simply return a pointer to the glyph data stored in the video ROM.

* [fbcon] Support Unicode character outputMichael Brown2022-03-151-2/+5
| | | | | | | Accumulate UTF-8 characters in fbcon_putchar(), and require the frame buffer console's .glyph() method to accept Unicode character values. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [fbcon] Centre background picture on consoleMichael Brown2014-01-221-8/+0Star
| | | | | | | | | | | | | | | | | | | | | | | Centre the background picture on the console, to give a more consistent result when the aspect ratio does not match the requested width and height. Once drawn for the first time, nothing should ever overwrite the margins of the display. We can therefore eliminate the logic used to redraw only the margin areas, and use much simpler code to draw the complete initial background image. Simplify the redrawing logic further by making the background picture buffer equal in size to the frame buffer. In the common case of a background picture which is designed to fill the screen, this wastes no extra memory, and the combined code simplifications reduce the size of fbcon.o by approximately 15%. Redefine the concept of "margin" to match the intuitive definition (i.e. the size of the gap, rather than the position of the boundary line). Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [fbcon] Add generic concept of a frame buffer consoleMichael Brown2013-11-281-0/+160
Add support for a simple frame buffer console, using single buffering and a fixed-width bitmap font. Signed-off-by: Michael Brown <mcb30@ipxe.org>
