| * [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 Brown2025-04-251-12/+10Star
| | | | | | | | | | | | | | | | | | | | | | | | 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.

| * [uaccess] Remove user_to_phys() and phys_to_user()Michael Brown2025-04-211-1/+1
| | | | | | | | | | | | | | | | Remove the intermediate concept of a user pointer from physical address conversions, leaving virt_to_phys() and phys_to_virt() as the directly implemented functions. Signed-off-by: Michael Brown <mcb30@ipxe.org>
| * [uaccess] Remove redundant memcpy_user() and related string functionsMichael Brown2025-04-211-2/+2
| | | | | | | | | | | | | | | | | | | | The memcpy_user(), memmove_user(), memcmp_user(), memset_user(), and strlen_user() functions are now just straightforward wrappers around the corresponding standard library functions. Remove these redundant wrappers. Signed-off-by: Michael Brown <mcb30@ipxe.org>

| * [efi] Support Unicode character output via framebuffer consoleMichael Brown2022-03-151-3/+48
| | | | | | | | | | | | | | Extend the glyph cache to include a number of dynamic entries that are populated on demand whenever a non-ASCII character needs to be drawn. Signed-off-by: Michael Brown <mcb30@ipxe.org>
| * [fbcon] Support Unicode character outputMichael Brown2022-03-151-70/+128
| | | | | | | | | | | | | | 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>

* [efi] Work around broken GetFontInfo() implementationsMichael Brown2016-03-101-16/+38
| | | | | | | | | | Several UEFI platforms are known to return EFI_NOT_FOUND when asked to retrieve the system default font information via GetFontInfo(). Work around these broken platforms by iterating over the glyphs to find the maximum height used by a printable character.
