Angel Pons | fb6606b | 2020-05-01 22:41:13 +0200 | [diff] [blame] | 9 | * IOSAV brings batch processing to memory training algorithms. |

Angel Pons | fb6606b | 2020-05-01 22:41:13 +0200 | [diff] [blame] | 11 | * The hardware is capable of executing a sequence of DRAM commands, |
| 12 | * which can be composed of up to four sub-sequences. |
Angel Pons | 7c49cb8 | 2020-03-16 23:17:32 +0100 | [diff] [blame] | 13 | * |
Angel Pons | fb6606b | 2020-05-01 22:41:13 +0200 | [diff] [blame] | 14 | * A sub-sequence (from now on, subseq) consists of executing the same |
| 15 | * DRAM command for a configurable number of times, with adjustable |
| 16 | * delay between the commands, as well as an address auto-increment |
| 17 | * value, which is added after a given number of command executions. |
| 18 | * |
| 19 | * There are four groups of registers in MCHBAR, one for each subseq. |
| 20 | * When firing up IOSAV, one needs to specify the number of subseqs it |
| 21 | * should use. |
| 22 | * |
| 23 | * The macros for these registers can take some integer parameters. |
| 24 | * Valid values are: |
| 25 | * channel: 0..1 or 3 to broadcast to all channels. |
| 26 | * index: 0..3 |
| 27 | * lane: 0..8 |
| 28 | * |
| 29 | * These ranges are inclusive: both upper and lower bounds are valid. |

Angel Pons | fb6606b | 2020-05-01 22:41:13 +0200 | [diff] [blame] | 36 | * Configures the row/column, bank and rank addresses. When a subseq |
| 37 | * begins to execute, the address fields define the address of the |
| 38 | * first command in the subseq. The address is updated after each |
| 39 | * command as configured in the "IOSAV_n_ADDR_UPDATE" registers, |
| 40 | * and the updated address is then written back into this register. |
