- UMA Carveout
- ============
- Some versions of Atom ROM expose available options for the VRAM carveout sizes,
- and allow changes to the carveout size via the ATCS function code 0xA on supported
- BIOS implementations.
- For those platforms, users can use the following files under uma/ to set the
- carveout size, in a way similar to what Windows users can do in the "Tuning"
- tab in AMD Adrenalin.
- Note that for BIOS implementations that don't support this, these files will not
- be created at all.
