The data fabric is the main component which routes transactions 22 * between entities (e.g. CPUS, DRAM, PCIe, etc.) in the system. The data fabric 23 * itself is made up of up to 8 PCI functions. There can be multiple instances 24 * of the data fabric. There is one instance per die. In most AMD processors 25 * after Zen 1, there is only a single die per socket, for more background see 26 * the uts/i86pc/os/cpuid.c big theory statement. All data fabric instances 27 * appear on PCI bus 0. The first instance shows up on device 0x18. Subsequent 28 * instances simply increment that number by one. 29 * 30 * There are currently four major revisions of the data fabric that are 31 * supported here, which are v2 (Zen 1), v3 (Zen 2/3), v3.5 (Zen 2/3 with DDR5), 32 * and v4 (Zen 4). In many cases, while the same logical thing exists in 33 * different generations, they often have different shapes and sometimes things 34 * with the same shape show up in different locations. As DFv4 has been extended 35 * across several different lines, things haven't been quite as smooth as we'd 36 * like in terms of DF representation. Certain things end up moving around much 37 * more liberally while revving the minor version of the DF, though at least we 38 * can still identify it as such. 39 * 40 * The major (relevant to us) distinction that we have found so far is that 41 * starting in DF 4v2 and greater, the way that DRAM was structured and the 42 * corresponding DRAM channel remap settings were moved. Because the DRAM base 43 * address registers were moved to 0x200, we call this DF_REV_4D2. If this 44 * gets much more nuanced, we should likely figure out if we want to encode 45 * minor versions in these constants and offer function pointers to get common 46 * things rather than forcing it onto clients. Note that this is very much a 47 * rough approximation and not really great. There are many places where the 48 * width of fields has changed slightly between minor revs, but are eating up 49 * more reserved bits, or not using quite as many. 50 * 51 * To make things a little easier for clients, each register definition encodes 52 * enough information to also include which hardware generations it supports, 53 * the actual PCI function it appears upon, and the register offset. This is to 54 * make sure that consumers don't have to guess some of this information in the 55 * latter cases and we can try to guarantee we're not accessing an incorrect 56 * register for our platform (unfortunately at runtime). 57 * 58 * Register definitions have the following form: 59 * 60 * DF_<reg name>_<vers> 61 * 62 * Here <reg name> is something that describes the register. This may not be the 63 * exact same as the PPR (processor programming reference); however, the PPR 64 * name for the register will be included above it in a comment (though these 65 * have sometimes changed from time to time). For example, DF_DRAM_HOLE. If a 66 * given register is the same in all currently supported versions, then there is 67 * no version suffix appended. Otherwise, the first version it is supported in 68 * is appended. For example, DF_DRAM_BASE_V2, DF_DRAM_BASE_V3, DF_DRAM_BASE_V4, 69 * etc. or DF_FIDMASK0_V3P5, etc. If the register offset is the same in multiple 70 * versions, then there they share the earliest version. 71 * 72 * For fields there are currently macros to extract these or chain them together 73 * leveraging bitx32() and bitset32(). Fields have the forms: 74 * 75 * DF_<reg name>_<vers>_GET_<field> 76 * DF_<reg name>_<vers>_SET_<field> 77 * 78 * Like in the above, if there are cases where a single field is the same across 79 * all versions, then the <vers> portion will be elided. There are many cases 80 * where the register definition does not change, but the fields themselves do 81 * change with each version because each hardware rev opts to be slightly 82 * different. 83 * 84 * When adding support for a new chip, please look carefully through the 85 * requisite documentation to ensure that they match what we see here. There are 86 * often cases where there may be a subtle thing or you hit a case like V3P5 87 * that until you dig deeper just seem to be weird. 88 */ 89 90 #include <sys/bitext.h> 91 92 #ifdef __cplusplus 93 extern "C" { 94 #endif 95 96 typedef enum df_rev { 97 DF_REV_UNKNOWN = 0, 98 DF_REV_2 = 1 << 0, 99 DF_REV_3 = 1 << 1, 100 DF_REV_3P5 = 1 << 2, 101 DF_REV_4 = 1 << 3, 102 /* 103 * This is a synthetic revision we make up per the theory statement that 104 * covers devices that have an updated DRAM layout. 105 */ 106 DF_REV_4D2 = 1 << 4 107 } df_rev_t; 108 109 #define DF_REV_ALL_3 (DF_REV_3 | DF_REV_3P5) 110 #define DF_REV_ALL_23 (DF_REV_2 | DF_REV_ALL_3) 111 #define DF_REV_ALL_4 (DF_REV_4 | DF_REV_4D2) 112 #define DF_REV_ALL (DF_REV_ALL_23 | DF_REV_ALL_4) 113 114 typedef struct df_reg_def { 115 df_rev_t drd_gens; 116 uint8_t drd_func; 117 uint16_t drd_reg; 118 } df_reg_def_t; 119 120 /* 121 * This set of registers provides us access to the count of instances in the 122 * data fabric and then a number of different pieces of information about them 123 * like their type.
