There are multiple sub-commands that 19 * vector into the same logic (e.g. 'save-cfgspace' and 'show-cfgspace'). In 20 * general, there are a few major goals with this bit of code: 21 * 22 * o Every field should strive to be parsable and therefore selectable for 23 * output. This drove the idea that every field has both a short name and a 24 * human name. The short name is a dot-delineated name. When in parsable 25 * mode, the name will always refer to a single field. However, for 26 * convenience for humans, when not trying to be parsable, we show the 27 * parents in the tree. That is if you specify something like 28 * 'pcie.linkcap.maxspeed', in parsable mode you'll only get that; however, 29 * in non-parsable mode, you'll get an indication of the capability and 30 * register that field was in. 31 * 32 * o Related to the above, parsable mode always outputs a raw, uninterpreted 33 * value. This was done on purpose. Some fields require interpreting multiple 34 * registers to have meaning and long strings aren't always the most useful. 35 * 36 * o Every field isn't always pretty printed. This was generally just a 37 * decision based upon the field itself and how much work it'd be to fit it 38 * into the framework we have. In general, the ones we're mostly guilty of 39 * doing this with are related to cases where there's a scaling value in a 40 * subsequent register. If you find yourself wanting this, feel free to add 41 * it. 42 * 43 * o Currently designated vendor-specific capabilities aren't included here (or 44 * any specific vendor-specific capabilities for that matter). If they are 45 * added, they should follow the same angle of using a name to represent a 46 * sub-capability as we did with HyperTransport. 47 */ 48 49 #include <err.h> 50 #include <strings.h> 51 #include <sys/sysmacros.h> 52 #include <sys/pci.h> 53 #include <sys/pcie.h> 54 #include <sys/debug.h> 55 #include <ofmt.h> 56 #include <sys/types.h> 57 #include <sys/stat.h> 58 #include <fcntl.h> 59 #include <unistd.h> 60 #include <sys/bitext.h> 61 62 #include "pcieadm.h" 63 64 typedef enum pcieadm_cfgspace_op { 65 PCIEADM_CFGSPACE_OP_PRINT, 66 PCIEADM_CFGSPACE_OP_WRITE 67 } pcieadm_cfgspace_op_t; 68 69 typedef enum piceadm_cfgspace_flag { 70 PCIEADM_CFGSPACE_F_PARSE = 1 << 0, 71 PCIEADM_CFGSPACE_F_SHORT = 1 << 1, 72 } pcieadm_cfgspace_flags_t; 73 74 typedef enum pcieadm_cfgspace_otype { 75 PCIEADM_CFGSPACE_OT_SHORT, 76 PCIEADM_CFGSPACE_OT_HUMAN, 77 PCIEADM_CFGSPACE_OT_VALUE 78 } pcieadm_cfgsapce_otype_t; 79 80 typedef struct pcieadm_cfgspace_ofmt { 81 const char *pco_base; 82 const char *pco_short; 83 const char *pco_human; 84 uint64_t pco_value; 85 const char *pco_strval; 86 } pcieadm_cfgspace_ofmt_t; 87 88 typedef enum pcieadm_regdef_val { 89 PRDV_STRVAL, 90 PRDV_BITFIELD, 91 PRDV_HEX 92 } pcieadm_regdef_val_t; 93 94 typedef struct pcieadm_regdef_addend { 95 uint8_t pra_shift; 96 int64_t pra_addend; 97 } pcieadm_regdef_addend_t; 98 99 typedef struct pcieadm_regdef { 100 uint8_t prd_lowbit; 101 uint8_t prd_hibit; 102 const char *prd_short; 103 const char *prd_human; 104 pcieadm_regdef_val_t prd_valtype; 105 union { 106 /* 107 * Enough space for up to an 8-bit fields worth of values 108 * (though we expect most to be sparse). 109 */ 110 const char *prdv_strval[128]; 111 pcieadm_regdef_addend_t prdv_hex; 112 } prd_val; 113 } pcieadm_regdef_t; 114 115 typedef struct pcieadm_unitdef { 116 const char *pcd_unit; 117 uint32_t pcd_mult; 118 } pcieadm_unitdef_t; 119 120 typedef struct pcieadm_strmap { 121 const char *psr_str; 122 uint64_t psr_val; 123 } pcieadm_strmap_t; 124 125 typedef struct pcieadm_cfgspace_filter { 126 const char *pcf_string; 127 size_t pcf_len; 128 boolean_t pcf_used; 129 } pcieadm_cfgspace_filter_t; 130 131 typedef struct pcieadm_strfilt { 132 struct pcieadm_strfilt *pstr_next; 133 const char *pstr_str; 134 char pstr_curgen[256]; 135 } pcieadm_strfilt_t; 136 137 /* 138 * Data is sized to be large enough that we can hold all of PCIe extended 139 * configuration space. 140 */ 141 typedef union pcieadm_cfgspace_data { 142 uint8_t pcb_u8[PCIE_CONF_HDR_SIZE]; 143 uint32_t pcb_u32[PCIE_CONF_HDR_SIZE / 4]; 144 } pcieadm_cfgspace_data_t; 145 146 typedef struct pcieadm_cfgspace_walk { 147 pcieadm_t *pcw_pcieadm; 148 pcieadm_cfgspace_op_t pcw_op; 149 uint32_t pcw_valid; 150 pcieadm_cfgspace_data_t *pcw_data; 151 uint16_t pcw_capoff; 152 uint32_t pcw_caplen; 153 int pcw_outfd; 154 uint_t pcw_dtype; 155 uint_t pcw_nlanes; 156 uint_t pcw_pcietype; 157 uint_t pcw_nfilters; 158 pcieadm_cfgspace_filter_t *pcw_filters; 159 pcieadm_cfgspace_flags_t pcw_flags; 160 ofmt_handle_t pcw_ofmt; 161 pcieadm_strfilt_t *pcw_filt; 162 } pcieadm_cfgspace_walk_t; 163 164 void 165 pcieadm_strfilt_pop(pcieadm_cfgspace_walk_t *walkp) 166 { 167 pcieadm_strfilt_t *filt; 168 169 VERIFY3P(walkp->pcw_filt, !=, NULL); 170 filt = walkp->pcw_filt; 171 walkp->pcw_filt = filt->pstr_next; 172 free(filt); 173 } 174 175 void 176 pcieadm_strfilt_push(pcieadm_cfgspace_walk_t *walkp, const char *str) 177 { 178 pcieadm_strfilt_t *filt; 179 size_t len; 180 181 filt = calloc(1, sizeof (*filt)); 182 if (filt == NULL) { 183 errx(EXIT_FAILURE, "failed to allocate memory for string " 184 "filter"); 185 } 186 187 filt->pstr_str = str; 188 if (walkp->pcw_filt == NULL) { 189 len = strlcat(filt->pstr_curgen, str, 190 sizeof (filt->pstr_curgen)); 191 } else { 192 len = snprintf(filt->pstr_curgen, sizeof (filt->pstr_curgen), 193 "%s.%s", walkp->pcw_filt->pstr_curgen, str); 194 filt->pstr_next = walkp->pcw_filt; 195 } 196 197 if (len >= sizeof (filt->pstr_curgen)) { 198 errx(EXIT_FAILURE, "overflowed internal string buffer " 199 "appending %s", str); 200 } 201 202 walkp->pcw_filt = filt; 203 } 204 205 static boolean_t 206 pcieadm_cfgspace_filter(pcieadm_cfgspace_walk_t *walkp, const char *str) 207 { 208 char buf[1024]; 209 size_t len; 210 211 if (walkp->pcw_nfilters == 0) { 212 return (B_TRUE); 213 } 214 215 if (str == NULL) { 216 return (B_FALSE); 217 } 218 219 if (walkp->pcw_filt != NULL) { 220 len = snprintf(buf, sizeof (buf), "%s.%s", 221 walkp->pcw_filt->pstr_curgen, str); 222 } else { 223 len = snprintf(buf, sizeof (buf), "%s", str); 224 } 225 226 if (len >= sizeof (buf)) { 227 abort(); 228 } 229 230 for (uint_t i = 0; i < walkp->pcw_nfilters; i++) { 231 if (strcmp(buf, walkp->pcw_filters[i].pcf_string) == 0) { 232 walkp->pcw_filters[i].pcf_used = B_TRUE; 233 return (B_TRUE); 234 } 235 236 /* 237 * If we're in non-parsable mode, we want to do a little bit 238 * more in a few cases.
