2017-07-25efi_loader: expose protocols via GUIDRob Clark
shim.efi (or rather gnu-efi's LibLocateProtocol() which shim.efi uses) resolves protocols via efi_locate_handle() so the console protocols need to be added to the efi object list. Signed-off-by: Rob Clark <robdclark@gmail.com> [agraf: whitespace fixes] Signed-off-by: Alexander Graf <agraf@suse.de>

2016-11-14efi_loader: console: Correctly report modesEmmanuel Vadot
Add support for EFI console modes. Mode 0 is always 80x25 and present by EFI specification. Mode 1 is always 80x50 and not mandatory. Mode 2 and above is freely usable. If the terminal can handle mode 1, we mark it as supported. If the terminal size is greater than mode 0 and different than mode 1, we install it as mode 2. Modes can be switch with cout_set_mode. Changes in V5: Correctly detect mode before enabling mode 2. Changes in V4: Reset cursor positon on mode switch Use local variables in console query code Changes in V3: Valid mode are 0 to EFIMode-1 Fix style Changes in V2: Add mode switch Report only the modes that we support Signed-off-by: Emmanuel Vadot <manu@bidouilliste.com> Signed-off-by: Alexander Graf <agraf@suse.de>
2016-03-15efi_loader: Add console interfaceAlexander Graf
One of the basic EFI interfaces is the console interface. Using it an EFI application can interface with the user. This patch implements an EFI console interface using getc() and putc(). Today, we only implement text based consoles. We also convert the EFI Unicode characters to UTF-8 on the fly, hoping that everyone managed to jump on the train by now.
