Backport EFI_HTTP_ERROR status code

2025-01-15T21:03:55+00:00

The define can be dropped when gnu-efi is updated to include de6f9259e8476495c78babbc25250a59de7f3942. Signed-off-by: Dan Nicholson

Rename 'msecs' to 'usecs' to avoid potential confusion

2023-06-21T18:19:51+00:00

The function msleep uses gBS->Stall which waits for a specified number of microseconds. Reference: https://edk2-docs.gitbook.io/edk-ii-uefi-driver-writer-s-guide/5_uefi_services/51_services_that_uefi_drivers_commonly_use/517_stall This reference even mentions an example sleeping for 10 microseconds: // Wait 10 uS. Notice the letter 'u'. Therefore it's a good idea to call the function 'usleep' rather than 'msleep', so no one confuses it with milliseconds, and to change the argument name to match as well.

Skip testing msleep()

2023-06-21T18:18:25+00:00

In preparation for renaming msleep() to usleep(), in some cases tests were failing due to a mismatch between our declaration of the usleep() function and what is being provided by unistd.h. This change simply makes our function declared only when not in a unit test environment. Signed-off-by: Kamil Aronowski

shim: use SHIM_DEVEL_VERBOSE when built in devel mode

2022-05-17T22:16:07+00:00

This makes SHIM_VERBOSE / SHIM_DEVEL_VERBOSE work the same way as SHIM_DEBUG / SHIM_DEVEL_DEBUG when shim is built with ENABLE_SHIM_DEVEL set. Signed-off-by: Peter Jones

Use ASCII as fallback if Unicode Box Drawing characters fail

2022-05-17T21:47:21+00:00

Many ASRock boards will not render MokManager correctly if the Unicode Box Drawing characters are used. Signed-off-by: Tony Persson

MokManager: removed Locate graphic output protocol fail error message

2022-03-30T17:22:42+00:00

On some platform, like GCP or OVMF which does NOT provide EFI_GRAPHICS_OUTPUT_PROTOCOL when no display device (or the display device be disabled). It causes that the "Error: Locate graphic output protocol fail: (0xE) Not Found." always be showed on console when we enroll MOK through MokManager. The message box blocked the process of enrolling MOK and scared user. The error message is introduced by 55163bc82c517 since 15.2. This patch removed the error message. Signed-off-by: Lee, Chun-Yi

console: add a clear_screen() primitive

2021-10-12T14:40:13+00:00

Several places in e.g. MokManager and our console library use ST->ConOut->ClearScreen directly, without checking for the existence of a console output device. This patch adds function to our console library to do that correctly, instead of using the bug-prone ad hoc implementation everywhere. Signed-off-by: Peter Jones

console: check that ST->ConIn and ST->ConOut are non-NULL

2021-10-12T14:40:13+00:00

There's been some discussion on how to handle machines without console devices. The consensus so far has been that they should have dummy ConOut implementations, but that means the first vendor to build a machine without asking around is in for some surprises. This patch makes the places where our console library uses ST->ConIn or ST->ConOut check that they're present before doing so. Signed-off-by: Peter Jones

shim/mm/fb: move global state to its own source file

2021-09-07T21:05:04+00:00

This moves the globals from shim.c (and lib/console.c) into their own file, to make it so that unit tests can more easily link against code that uses that state. Signed-off-by: Peter Jones

cleanup: always use BS and RT, not gBS and gRT

2021-09-07T21:05:04+00:00

This just makes one less thing we have to make sure is the same between the test harnesses and the runtime code. Signed-off-by: Peter Jones
