994 * copy and automatically transfer them into the real register the next time
995 * the power well is woken up. Shadowing only applies to writes; forcewake
996 * must still be acquired when reading from registers in these ranges.

998 * The documentation for shadowed registers is somewhat spotty on older

1000 * means we'll wake up the hardware for some register accesses where we didn't
1001 * really need to.
1002 *
1003 * The ranges listed in these tables must be sorted by offset.
1004 *
1005 * When adding new tables here, please also add them to
1006 * intel_shadow_table_check() in selftests/intel_uncore.c so that they will be
1007 * scanned for obvious mistakes or typos by the selftests.

1217/*
1218 * All platforms' forcewake tables below must be sorted by offset ranges.
1219 * Furthermore, new forcewake tables added should be "watertight" and have
1220 * no gaps between ranges.
1221 *
1222 * When there are multiple consecutive ranges listed in the bspec with
1223 * the same forcewake domain, it is customary to combine them into a single
1224 * row in the tables below to keep the tables small and lookups fast.
1225 * Likewise, reserved/unused ranges may be combined with the preceding and/or
1226 * following ranges since the driver will never be making MMIO accesses in
1227 * those ranges.
1228 *
1229 * For example, if the bspec were to list:
1230 *
1231 * ...
1232 * 0x1000 - 0x1fff: GT
1233 * 0x2000 - 0x2cff: GT
1234 * 0x2d00 - 0x2fff: unused/reserved
1235 * 0x3000 - 0xffff: GT
1236 * ...
1237 *
1238 * these could all be represented by a single line in the code:
1239 *
1240 * GEN_FW_RANGE(0x1000, 0xffff, FORCEWAKE_GT)
1241 *
1242 * When adding new forcewake tables here, please also add them to
1243 * intel_uncore_mock_selftests in selftests/intel_uncore.c so that they will be
1244 * scanned for obvious mistakes or typos by the selftests.
