To: amd-gfx; +Cc: alexander.deucher, ray.huang, nirmoy.das, christian.koenig
Generate HW IP's sched_list in amdgpu_ring_init() instead of
amdgpu_ctx.c. This makes amdgpu_ctx_init_compute_sched(),
ring.has_high_prio and amdgpu_ctx_init_sched() unnecessary.
This patch also stores sched_list for all HW IPs in one big
array in struct amdgpu_device which makes amdgpu_ctx_init_entity()
much more leaner.
v2:
fix a coding style issue
do not use drm hw_ip const to populate amdgpu_ring_type enum
v3:
remove ctx reference and move sched array and num_sched to a struct
use num_scheds to detect uninitialized scheduler list

That's a 2-dimensional array of "struct amdgpu_sched".
I think that the comment should be removed, or at least
not say "drm scheduler list". (I can see the structure
definition above.)
If this is the path you want to go, consider removing
"num_scheds" and creating a three dimensional array,
which would really essentialize the direction you want
to go:
struct drm_gpu_scheduler *gpu_sched[AMDGPU_HW_IP_NUM][AMDGPU_RING_PRIO_MAX][HWIP_MAX_INSTANCE];
Now that this architecture is stripped down to its essentials,
perhaps we can see some optimizations...?
Also consider that since you're creating an array of pointers,
you don't necessarily need to know their count. Your hot-path
algorithms should not need to know it. If you need to print
their count, say in sysfs, then you can count them up on
behalf of the user-space process cat-ing the sysfs entry.

The name of this function could be normalized from
the current pattern of "sched_prio_to_hw_prio" where "prio"
is repeated, to <domain>-<from>-<to> as follows:
amdgpu_ctx_prio_sched_to_hw(...)
Where the domain is "priority" and we're converting from "scheduler"
to "hw" priority.

Parenthesis are unnecessary--relational = has higher priority than
ternary operator.

That comment is a bit confusing--it talks about a list
not being NULL, while the conditional implicitly checks
against 0.
I'd much rather that integer comparison be performed against
integers, as opposed to using logical NOT operator (which is
implicit in comparing against 0), i.e.,
if (adev->gpu_sched[hw_ip][hw_prio].num_scheds == 0)
Also, architecturally, there seems to be informational
redundancy, in keeping an integer count and list of
objects at the same time, as the above if-conditional
exposes: the comment talks about a list and NULL but
the if-conditional implicitly checks for 0.
Perhaps, we don't need "num_scheds" and you can just
check if the index is NULL and assign PRIO_DEFAULT.

BTW: You need to be careful when indexing into this by an user specified
value, e.g. use array_index_nospec().

Please don't use a map for this, it is a 1 to 1 mapping as far as I can

Yes I should remove it.

If you mean whether we should see any performance improvement then imo
we may not see much
difference as we are using pretty much same number of memory access plus
now we have extra cost of array_index_nospec().
Also this is not hot code path. We do only 1
amdgpu_ctx_init_entity()/HW_IP/Context.

Yes, this is wrong, will remove it.

What do you mean by running pointer ?

Not sure why "git am" complained about DOS endings

No, this has nothing to do with "performance".
It's all about architecture and design.
You seem to have array-array-struct with array and int,
and it seems much cleaner to just have array-array-array.
I think you don't need to break the chain with
struct of int and array, just as I described
in my comment below which you snipped without addressing it.
If you're not going to address a comment, don't delete it, leave it
for others to see that it hasn't been addressed. Only
snip previously addressed and resolved comments and previously
seen patch info, like diffstat/etc.

I wish you hadn't snipped my comment here, but address it
one way or the other. It is:
I'd much rather that integer comparison be performed against
integers, as opposed to using logical NOT operator (which is
implicit in comparing against 0), i.e.,
if (adev->gpu_sched[hw_ip][hw_prio].num_scheds == 0)
Also, architecturally, there seems to be informational
redundancy, in keeping an integer count and list of
objects at the same time, as the above if-conditional
exposes: the comment talks about a list and NULL but
the if-conditional implicitly checks for 0.
Perhaps, we don't need "num_scheds" and you can just
check if the index is NULL and assign PRIO_DEFAULT.

A "running pointer" is a local pointer you're using temporarily
to traverse memory. If you remove the "num_scheds", as noted in my
previous comment, then you can use a running pointer to contain
the next entry you'd initialize.

I wanted to understand "running pointer" before I could comment in there.

Number of valid drm scheduler in adev->gpu_sched[hw_ip][hw_prio].sched
will vary depending on priority and hw_ip.
We need to pass that scheduler array and num_scheds to
drm_sched_entity_init(). I think we often use
array and integer count together when the number of valid items in the
array is dynamic.

Okay I understand now. As I said we need to know the valid number of
scheduler in a sched array so that we can pass that information to
drm_sched_entity_init() .
