Are these bits? Perhaps BIT() ?
isn't it just better to use fixed size as u suggest in the next
comment?
If the are bits, use BIT() macro.
+struct llcc_slice_desc *llcc_slice_getd(u32 uid)

+ struct llcc_slice_desc *desc;
+ u32 sz, count = 0;

+ break;
+ cfg++;
+ count++;

+ return ERR_PTR(-ENODEV);
if (!cfg)
return ERR_PTR(-ENODEV);
while (cfg->... != uid) {
cfg++;
count++;
}
if (count == sz)
return ...
Though I would rather put it to for () loop.
In each while loop iteration the cfg pointer needs to be checked for
NULL. What if the usecase id never matches the uid passed by client
and we keep iterating. At some point it will crash.
do {
if (!cfg || count == sz)
return ...(-ENODEV);
...
} while (...);
Though, as I said for-loop will look slightly better I think.
Is this fine?
for (count = 0; count < sz; count++) {
if (!cfg)
return ERR_PTR(-ENODEV);
if (cfg->usecase_id == uid)
break;
cfg++;
}
if (count == sz)
return ERR_PTR(-ENODEV);
+ ret = llcc_update_act_ctrl(desc->slice_id, act_ctrl_val,
+ DEACTIVATE);
Perhaps one line (~83 characters here is OK) ?
The checkpatch script complains about such lines.
So what if it just 3 characters out?
Other reviewers sometimes are not okay if the checkpatch complains.
Because I have gotten many reviews previously concerning about line
length. Not sure how to proceed here.
+ ret = llcc_update_act_ctrl(desc->slice_id, act_ctrl_val,
+ ACTIVATE);
Ditto.
+ attr1_cfg = bcast_off +
+
LLCC_TRP_ATTR1_CFGn(llcc_table[i].slice_id);
+ attr0_cfg = bcast_off +
+
LLCC_TRP_ATTR0_CFGn(llcc_table[i].slice_id);
Ditto.
+ attr1_val |= llcc_table[i].probe_target_ways <<
+ ATTR1_PROBE_TARGET_WAYS_SHIFT;
+ attr1_val |= llcc_table[i].fixed_size <<
+ ATTR1_FIXED_SIZE_SHIFT;
+ attr1_val |= llcc_table[i].priority <<
ATTR1_PRIORITY_SHIFT;
foo |=
bar << SHIFT;
would look slightly better.
Did you consider this option ?
Yes, forgot to mention.
