====================================␊
- Integrate Prasys current work on options and quick shortcut modified version of 18seven␊
␊
- Add autodetection of efistring algorythm to enabke graphics enabler to beanbled by default while not conflicting whith other efi string overriden content␊
- Add autodetection of efistring algorithm to enable graphics enabler to be enabled by default while not conflicting with other efi string overriden content␊
(original idea of Galaxy)␊
␊
- Add a more sophisticated acpi loading mechanism to enable loading custom acpi tables when dsdtdrop=y␊
Now for each acpi file found, we should compare the name with an existing acpi table found in the system that␊
we would normally load and replace this usual injection by the content of the file.␊
␊
Once DropDSDT=y is set, no other acpi table than dsdt is loaded, then it is the responsability of user␊
Once DropDSDT=y is set, no other acpi table than dsdt is loaded, then it is the responsibility of user␊
to provide any other acpi table.␊
␊
- Add a new module capable of writing proprietary Chameleon data to ioreg:␊
Using the DT__xxx() API, we will creat e a set of functions to write␊
Using the DT__xxx() API, we will create a set of functions to write␊
to log info, chameleon boot info to be retrieved by helper applications...␊
the only public function for log info purpose of this module would be:␊
logMessageToIOREG(...); // var args printf style format␊
