Can we avoid pointers to separate blob definitions ?
What about defining each fw in single line like below
#define INTEL_GUC_FIRMWARE_DEFS(fw_def) \
fw_def(ICELAKE, 0, 33, 0, 0, icl, GUC) \
fw_def(COFFEELAKE, 0, 33, 0, 0, kbl, GUC) \
fw_def(GEMINILAKE, 0, 33, 0, 0, glk, GUC) \
fw_def(KABYLAKE, 0, 33, 0, 0, kbl, GUC) \
fw_def(BROXTON, 0, 33, 0, 0, bxt, GUC) \
fw_def(SKYLAKE, 0, 33, 0, 0, skl, GUC) \
/* end */
with some extra common helpers
#define TO_MODULE_FIRMWARE(_platform, _rev, _major, _minor, _patch,
_prefix, _builder) \
MODULE_FIRMWARE(_builder##_FW_PATH_BUILDER(_prefix, _major, _minor,
_patch));
#define TO_BLOB_ENTRY(_platform, _rev, _major, _minor, _patch, _prefix,
_builder) \
{ \
.platform = INTEL_##_platform, \
.rev = (_rev), \
.major = (_major), \
.minor = (_minor), \
.patch = (_patch), \
.blob = _builder##_FW_PATH_BUILDER(_prefix, _major, _minor, _patch), \
},
then we can have immutable
static const struct intel_uc_blob guc_fw_blobs[] = {
INTEL_GUC_FIRMWARE_DEFS(TO_BLOB_ENTRY)
};
INTEL_GUC_FIRMWARE_DEFS(TO_MODULE_FIRMWARE)
(tested locally for feasibility)
