函数名称：decode_uv_systab

函数原型：static int __init decode_uv_systab(void)

返回类型：int

参数：无

1308  如果is_uv_hubbed(0xfffffe)小于uv(4)且is_uv_hubless(0xfffffe)小于uv(4)则返回:0
1311  st等于uv_systab
1312  如果非st或distinguish different firmware revs 小于UV_SYSTAB_VERSION_UV4_LATEST则
1313  rev等于如果st则distinguish different firmware revs 否则0
1315  打印错误信息("UV: BIOS UVsystab version(%x) mismatch, expecting(%x)\n", rev, UV_SYSTAB_VERSION_UV4_LATEST)
1316  打印错误信息("UV: Cannot support UV operations, switching to generic PC\n")
1317  uv_system_type = UV_NONE
1319  返回:负EINVAL
1322  以 type of entry 不等于End of table (offset == 0) 循环
1323  ptr等于 byte offset from struct start to entry
1325  如果非ptr则继续下一循环
1328  ptr等于ptr加st
1331  当: type of entry 恒等于GAM PARAM conversions
1332  decode_gam_params(ptr)
1333  退出
1335  当: type of entry 恒等于GAM entry table
1336  decode_gam_rng_tbl(ptr)
1337  退出
1340  返回:0
