hmm, GUC_CTL_MAX_DWORDS is 14, so it will be 56 bytes in total,
but hex_dump_to_buffer will dump only 32 bytes ... unless
we explicitly limit our dump to currently used just 5 entries
(20 bytes) but then this might be not future proof if new fw
will require/use more then 8 parameters
+ DRM_DEBUG_DRIVER("params[%s]\n", buf);
use of [%s] may make this less readable, so maybe:
DRM_DEBUG_DRIVER("GuC params %s\n", buf);
but I'm still not sure if we should go that partial way, Daniele ?
Michal
ps. we can aslo use two lines or two bufs for 0..7 and 8..13 params
