| 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. |
