SBSA is EDK2 based, which is basically incredibly painful to patch.  The source files are windows-style CR/LF so your patch needs to have CR/LF, but if the whole patch has CR/LF then git “helpfully” transforms the patch to just unix-style LF, which doesn’t apply.


The “solution” (workaround) is to convert the patch to LF encoding, and manually add the CR characters to the end of each line in the patch body.


The good news is that EDK2 is moving to LF encoding, so this will be solved at some point.

I am seeing an error when I attempt to apply a patch, and could use some clarification or way to resolve…


Am doing something wrong in patch creation ?

What is meant by :  ”Patch console.patch does not apply (enforce with -f)” ?

How can I best resolve this issue ?


I edited a file in the recipe’s git repo in order to create the patch for the change:


git diff -u console.c


which I used as my patch:


diff --git a/lib/console.c b/lib/console.c

index 9c10560..b932a44 100644

I am getting the following error when the patch is applied:
