| 8 | * ### IOSAV command queue notes ### |
| 9 | * |
| 10 | * Intel provides a command queue of depth four. |
| 11 | * Every command is configured by using multiple MCHBAR registers. |
| 12 | * On executing the command queue, you have to specify its depth (number of commands). |
| 13 | * |
| 14 | * The macros for these registers can take some integer parameters, within these bounds: |
| 15 | * channel: [0..1] |
| 16 | * index: [0..3] |
| 17 | * lane: [0..8] |
| 18 | * |
| 19 | * Note that these ranges are 'closed': both endpoints are included. |
| 20 | * |
| 21 | * |
| 22 | * |
| 23 | * ### Register description ### |
| 24 | * |
| 25 | * IOSAV_n_SP_CMD_ADDR_ch(channel, index) |
| 26 | * Sub-sequence command addresses. Controls the address, bank address and slotrank signals. |
| 27 | * |
| 28 | * Bitfields: |
| 29 | * [0..15] Row / Column Address. |
| 30 | * [16..18] The result of (10 + [16..18]) is the number of valid row bits. |
| 31 | * Note: Value 1 is not implemented. Not that it really matters, though. |
| 32 | * Value 7 is reserved, as the hardware does not support it. |
| 33 | * [20..22] Bank Address. |
| 34 | * [24..25] Rank select. Let's call it "ranksel", as it is mentioned later. |
| 35 | * |
| 36 | * IOSAV_n_ADDR_UPDATE_ch(channel, index) |
| 37 | * How the address shall be updated after executing the sub-sequence command. |
| 38 | * |
| 39 | * Bitfields: |
| 40 | * [0] Increment CAS/RAS by 1. |
| 41 | * [1] Increment CAS/RAS by 8. |
| 42 | * [2] Increment bank select by 1. |
| 43 | * [3..4] Increment rank select by 1, 2 or 3. |
| 44 | * [5..9] Known as "addr_wrap". Address bits will wrap around the [addr_wrap..0] range. |
| 45 | * [10..11] LFSR update: |
| 46 | * 00: Do not use the LFSR function. |
| 47 | * 01: Undefined, treat as Reserved. |
| 48 | * 10: Apply LFSR on the [addr_wrap..0] bit range. |
| 49 | * 11: Apply LFSR on the [addr_wrap..3] bit range. |
| 50 | * |
| 51 | * [12..15] Update rate. The number of command runs between address updates. For example: |
| 52 | * 0: Update every command run. |
| 53 | * 1: Update every second command run. That is, half of the command rate. |
| 54 | * N: Update after N command runs without updates. |
| 55 | * |
| 56 | * [16..17] LFSR behavior on the deselect cycles (when no sub-seq command is issued): |
| 57 | * 0: No change w.r.t. the last issued command. |
| 58 | * 1: LFSR XORs with address & command (excluding CS), but does not update. |
| 59 | * 2: LFSR XORs with address & command (excluding CS), and updates. |
| 60 | * |
| 61 | * IOSAV_n_SP_CMD_CTRL_ch(channel, index) |
| 62 | * Special command control register. Controls the DRAM command signals. |
| 63 | * |
| 64 | * Bitfields: |
| 65 | * [0] !RAS signal. |
| 66 | * [1] !CAS signal. |
| 67 | * [2] !WE signal. |
| 68 | * [4..7] CKE, per rank and channel. |
| 69 | * [8..11] ODT, per rank and channel. |
| 70 | * [12] Chip Select mode control. |
| 71 | * [13..16] Chip select, per rank and channel. It works as follows: |
| 72 | * |
| 73 | * entity CS_BLOCK is |
| 74 | * port ( |
| 75 | * MODE : in std_logic; -- Mode select at [12] |
| 76 | * RANKSEL : in std_logic_vector(0 to 3); -- Decoded "ranksel" value |
| 77 | * CS_CTL : in std_logic_vector(0 to 3); -- Chip select control at [13..16] |
| 78 | * CS_Q : out std_logic_vector(0 to 3) -- CS signals |
| 79 | * ); |
| 80 | * end entity CS_BLOCK; |
| 81 | * |
| 82 | * architecture RTL of CS_BLOCK is |
| 83 | * begin |
| 84 | * if MODE = '1' then |
| 85 | * CS_Q <= not RANKSEL and CS_CTL; |
| 86 | * else |
| 87 | * CS_Q <= CS_CTL; |
| 88 | * end if; |
| 89 | * end architecture RTL; |
| 90 | * |
| 91 | * [17] Auto Precharge. Only valid when using 10 row bits! |
| 92 | * |
| 93 | * IOSAV_n_SUBSEQ_CTRL_ch(channel, index) |
| 94 | * Sub-sequence parameters. Controls repetititons, delays and data orientation. |
| 95 | * |
| 96 | * Bitfields: |
| 97 | * [0..8] Number of repetitions of the sub-sequence command. |
| 98 | * [10..14] Gap, number of clock-cycles to wait before sending the next command. |
| 99 | * [16..24] Number of clock-cycles to idle between sub-sequence commands. |
| 100 | * [26..27] The direction of the data. |
| 101 | * 00: None, does not handle data |
| 102 | * 01: Read |
| 103 | * 10: Write |
| 104 | * 11: Read & Write |
| 105 | * |
| 106 | * IOSAV_n_ADDRESS_LFSR_ch(channel, index) |
| 107 | * 23-bit LFSR state register. It is written into the LFSR when the sub-sequence is loaded, |
| 108 | * and then read back from the LFSR when the sub-sequence is done. |
| 109 | * |
| 110 | * Bitfields: |
| 111 | * [0..22] LFSR state. |
| 112 | * |
| 113 | * IOSAV_SEQ_CTL_ch(channel) |
| 114 | * Control the sequence level in IOSAV: number of sub-sequences, iterations, maintenance... |
| 115 | * |
| 116 | * Bitfields: |
| 117 | * [0..7] Number of full sequence executions. When this field becomes non-zero, then the |
| 118 | * sequence starts running immediately. This value is decremented after completing |
| 119 | * a full sequence iteration. When it is zero, the sequence is done. No decrement |
| 120 | * is done if this field is set to 0xff. This is the "infinite repeat" mode, and |
| 121 | * it is manually aborted by clearing this field. |
| 122 | * |
| 123 | * [8..16] Number of wait cycles after each sequence iteration. This wait's purpose is to |
| 124 | * allow performing maintenance in infinite loops. When non-zero, RCOMP, refresh |
| 125 | * and ZQXS operations can take place. |
| 126 | * |
| 127 | * [17] Stop-on-error mode: Whether to stop sequence execution when an error occurs. |
| 128 | * [18..19] Number of sub-sequences. The programmed value is the index of the last sub-seq. |
| 129 | * [20] If set, keep refresh disabled until the next sequence execution. |
| 130 | * DANGER: Refresh must be re-enabled within the (9 * tREFI) period! |
| 131 | * |
| 132 | * [22] If set, sequence execution will not prevent refresh. This cannot be set when |
| 133 | * bit [20] is also set, or was set on the previous sequence. This bit exists so |
| 134 | * that the sequence machine can be used as a timer without affecting the memory. |
| 135 | * |
| 136 | * [23] If set, a output pin is asserted on the first detected error. This output can |
| 137 | * be used as a trigger for an oscilloscope or a logic analyzer, which is handy. |
| 138 | * |
| 139 | * IOSAV_DATA_CTL_ch(channel) |
| 140 | * Data-related controls in IOSAV mode. |
| 141 | * |
| 142 | * Bitfields: |
| 143 | * [0..7] WDB (Write Data Buffer) pattern length: [0..7] = (length / 8) - 1; |
| 144 | * [8..15] WDB read pointer. Points at the data used for IOSAV write transactions. |
| 145 | * [16..23] Comparison pointer. Used to compare data from IOSAV read transactions. |
| 146 | * [24] If set, increment pointers only when micro-breakpoint is active. |
| 147 | * |
| 148 | * IOSAV_STATUS_ch(channel) |
| 149 | * State of the IOSAV sequence machine. Should be polled after sending an IOSAV sequence. |
| 150 | * |
| 151 | * Bitfields: |
| 152 | * [0] IDLE: IOSAV is sleeping. |
| 153 | * [1] BUSY: IOSAV is running a sequence. |
| 154 | * [2] DONE: IOSAV has completed a sequence. |
| 155 | * [3] ERROR: IOSAV detected an error and stopped on it, when using Stop-on-error. |
| 156 | * [4] PANIC: The refresh machine issued a Panic Refresh, and IOSAV was aborted. |
| 157 | * [5] RCOMP: RComp failure. Unused, consider Reserved. |
| 158 | * [6] Cleared with a new sequence, and set when done and refresh counter is drained. |
