Good point, thanks, I will update it for v4.
I'm finally noticing that these counters are not really from hvhdk.h, in
the windows code, but their own file. Since I'm still iterating on this,
what do you think about creating a file just for the counters?
e.g. drivers/hv/hvcounters.h, which combines hvcountersarm64 and amd64.
That would have a couple of advantages:
1. Not putting things in hvhdk.h which aren't actually there in the
Windows source
2. Less visibility of CamelCase naming outside our driver
3. I could define the enums using "X macro"s to generate the show() code
more cleanly in mshv_debugfs.c, which is something Michael suggested
here:
https://lore.kernel.org/linux-hyperv/SN6PR02MB4157938404BC0D12978ACD9BD4A2A@SN6PR02MB4157.namprd02.prod.outlook.com/
It would look something like this:
In hvcounters.h:
#if is_enabled(CONFIG_X86_64)
#define HV_COUNTER_VP_LIST(X) \
X(VpTotalRunTime, 1), \
X(VpHypervisorRunTime, 2), \
X(VpRemoteNodeRunTime, 3), \
/* <snip> */
#elif is_enabled(CONFIG_ARM64)
/* <snip> */
#endif
Just like now, it's a copy/paste from Windows + simple pattern
replacement. Note with this approach we need separate lists for arm64
and x86, but that matches how the enums are defined in Windows.
Then, in mshv_debugfs.c:
/*
* We need the strings paired with their enum values.
* This structure can be used for all the different stat types.
*/
struct hv_counter_entry {
char *name;
int idx;
};
/* Define an array entry (again, reusable) */
#define HV_COUNTER_LIST(name, idx) \
{ __stringify(name), idx },
/* Create our static array */
static struct hv_counter_entry hv_counter_vp_array[] = {
HV_ST_COUNTER_VP(HV_COUNTER_VP)
};
static int vp_stats_show(struct seq_file *m, void *v)
{
const struct hv_stats_page **pstats = m->private;
int i;
for (i = 0; i < ARRAY_SIZE(hv_counter_vp_array); ++i) {
struct hv_counter_entry entry = hv_counter_vp_array[i];
u64 parent_val = pstats[HV_STATS_AREA_PARENT]->vp_cntrs[entry.idx];
u64 self_val = pstats[HV_STATS_AREA_SELF]->vp_cntrs[entry.idx];
/* Prioritize the PARENT area value */
seq_printf(m, "%-30s: %llu\n", entry.name,
parent_val ? parent_val : self_val);
}
}
Any thoughts? I was originally going to just go with the pattern we had,
but since these definitions aren't from the hv*dk.h files, we can maybe
get more creative and make the resulting code look a bit better.
Thanks
Nuno
