| /* |
| * GOYA security scheme: |
| * |
| * 1. Host is protected by: |
| * - Range registers (When MMU is enabled, DMA RR does NOT protect host) |
| * - MMU |
| * |
| * 2. DRAM is protected by: |
| * - Range registers (protect the first 512MB) |
| * - MMU (isolation between users) |
| * |
| * 3. Configuration is protected by: |
| * - Range registers |
| * - Protection bits |
| * |
| * When MMU is disabled: |
| * |
| * QMAN DMA: PQ, CQ, CP, DMA are secured. |
| * PQ, CB and the data are on the host. |
| * |
| * QMAN TPC/MME: |
| * PQ, CQ and CP are not secured. |
| * PQ, CB and the data are on the SRAM/DRAM. |
| * |
| * Since QMAN DMA is secured, KMD is parsing the DMA CB: |
| * - KMD checks DMA pointer |
| * - WREG, MSG_PROT are not allowed. |
| * - MSG_LONG/SHORT are allowed. |
| * |
| * A read/write transaction by the QMAN to a protected area will succeed if |
| * and only if the QMAN's CP is secured and MSG_PROT is used |
| * |
| * |
| * When MMU is enabled: |
| * |
| * QMAN DMA: PQ, CQ and CP are secured. |
| * MMU is set to bypass on the Secure props register of the QMAN. |
| * The reasons we don't enable MMU for PQ, CQ and CP are: |
| * - PQ entry is in kernel address space and KMD doesn't map it. |
| * - CP writes to MSIX register and to kernel address space (completion |
| * queue). |
| * |
| * DMA is not secured but because CP is secured, KMD still needs to parse the |
| * CB, but doesn't need to check the DMA addresses. |
| * |
| * For QMAN DMA 0, DMA is also secured because only KMD uses this DMA and KMD |
| * doesn't map memory in MMU. |
| * |
| * QMAN TPC/MME: PQ, CQ and CP aren't secured (no change from MMU disabled mode) |
| * |
| * DMA RR does NOT protect host because DMA is not secured |
