This change updates grub to the 2.04 release. The new release changed how grub is built, so the bootstrap and bootstrap.conf files have to be added to the dist-git. Also, the gitignore file changed so it has to be updated. Since the patches have been forward ported to 2.04, there's no need for a logic to maintain a patch with the delta between the release and the grub master branch. So the release-to-master.patch is dropped and no longer is updated by the do-rebase script. Also since gnulib isn't part of the grub repository anymore and cloned by the boostrap tool, a gnulib tarball is included as other source file and copied before calling the bootstrap tool. That way grub can be built even in builders that only have access to the sources lookaside cache. Resolves: rhbz#1727279 Signed-off-by: Javier Martinez Canillas <javierm@redhat.com>

Subject: [PATCH] EFI: console: Add grub_console_read_key_stroke() helper
|
|
function
|
|
|
|
This is a preparation patch for adding getkeystatus() support to the
|
|
EFI console terminal input driver.
|
|
|
|
We can get modifier status through the simple_text_input read_key_stroke
|
|
method, but if a non-modifier key is (also) pressed the read_key_stroke
|
|
call will consume that key from the firmware's queue.
|
|
|
|
The new grub_console_read_key_stroke() helper buffers upto 1 key-stroke.
|
|
If it has a non-modifier key buffered, it will return that one, if its
|
|
buffer is empty, it will fills its buffer by getting a new key-stroke.
|
|
|
|
If called with consume=1 it will empty its buffer after copying the
|
|
key-data to the callers buffer, this is how getkey() will use it.
|
|
|
|
If called with consume=0 it will keep the last key-stroke buffered, this
|
|
is how getkeystatus() will call it. This means that if a non-modifier
|
|
key gets pressed, repeated getkeystatus() calls will return the modifiers
|
|
of that key-press until it is consumed by a getkey() call.
