[Intel-gfx] [PATCH v2 0/8] Prep work for next GuC release

[Intel-gfx] [PATCH v2 0/8] Prep work for next GuC release

[John.C.Harrison]

From: John Harrison <John.C.Harrison@Intel.com>

The next GuC firmware release includes some significant backwards
breaking API changes. One such is that there is no longer an LRC
descriptor pool. A bunch of prep work for that change can be done in
advance - the descriptor pool was being used for things it shouldn't
really have been used for anyway.

v2: Extend commit message on 'better name' patch. Improve 'split
apart' patch to include some necessary re-arrangement that was in a
later patch and which introduced an unnecessary conditional in said
patch too. (review feedback from Daniele)

[Intel-gfx] [PATCH v2 1/8] drm/i915/guc: Do not conflate lrc_desc with GuC id for registration

[John.C.Harrison]

From: John Harrison <John.C.Harrison@Intel.com>

The LRC descriptor pool is going away. So, stop using it as a check for
context registration, use the GuC id instead (being the thing that
actually gets registered with the GuC).

Also, rename the set/clear/query helper functions for context id
mappings to better reflect their purpose and to differentiate from
other registration related helper functions.

There are a plethora of static inlines in the guc .c files, and this
adds more. How about just letting the compiler decide what's the best
course of action, inline or not? I think hand rolling the inline is a
micro optimization that you'd need to justify i.e. show that you're
doing a better job than the compiler.

The main downsides to using inlines are that you'll miss compiler
warnings for unused functions, and it sets an example for people to
start using inline more, while they should be an exception.

BR,
Jani.


PS. I also don't much like the likely/unlikely annotations, but that's
another can of worms.

Technically, this patch isn't adding any new ones. It is just reworking 
existing functions in their existing style. So it basically comes under 
your last point of people just following the prevailing style because 
it's already there.

I can add a task to the clean-up backlog to remove all mention of 
inline. Not sure why you think the (un)likely tags are bad? Again, I 
have no particular view either way.

John.

The (un)likely annotations are similar to static inlines in that they're
often unjustified micro optimizations. Having plenty of them gives
people the false impression using them should be the rule rather than
the exception. And getting them wrong could have a high performance
penalty. They're certainly not meant for regular error handling.

Similar to static inlines, (un)likely have their uses, but they need to
be used sparingly and the use needs to be justified. For static inlines,
especially within .c files, just let the compiler do its job. For
(un)likely, just let the CPU branch predictor do its job.

The link's pretty old, but see also: https://lwn.net/Articles/420019/


BR,
Jani.

[Intel-gfx] [PATCH v2 2/8] drm/i915/guc: Add an explicit 'submission_initialized' flag

[John.C.Harrison]

From: John Harrison <John.C.Harrison@Intel.com>

The LRC descriptor pool is going away. So, stop using it as a check
for whether submission has been initialised or not.

[Intel-gfx] [PATCH v2 3/8] drm/i915/guc: Better name for context id limit

[John.C.Harrison]

From: John Harrison <John.C.Harrison@Intel.com>

The LRC descriptor pool is going away. So, stop using it as the limit
for how many context ids are available. Instead, size the pool
according to the number of contexts allowed. Note that this is just a
naming change, the actual limit is identical in value.

While at it, also update a kzalloc(sizeof()*count) to be a
kcalloc(count,size).

[John.C.Harrison]

From: John Harrison <John.C.Harrison@Intel.com>

The LRC descriptor pool is going away. Further, the function that was
populating it was also doing a bunch of logic about the context
registration sequence. So, split that code apart into separate state
setup and try to register functions. Note that some of those 'try to
register' code paths actually undo the state setup and leave it to be
redone again later (with potentially different values). This is
inefficient. The next patch will correct this.

Also, move a comment about ignoring return values to the place where
the return values are actually ignored.

v2: Move some more splitting from a later patch (and do it correctly).

[Intel-gfx] [PATCH v2 5/8] drm/i915/guc: Move lrc desc setup to where it is needed

[John.C.Harrison]

From: John Harrison <John.C.Harrison@Intel.com>

The LRC descriptor was being initialised early on in the context
registration sequence. It could then be determined that the actual
registration needs to be delayed and the descriptor would be wiped
out. This is inefficient, so move the setup to later in the process
after the point of no return.

v2: Move some split changes into the split patch (and do them
correctly).

[Intel-gfx] [PATCH v2 6/8] drm/i915/guc: Rename desc_idx to ctx_id

[John.C.Harrison]

From: John Harrison <John.C.Harrison@Intel.com>

The LRC descriptor pool is going away. So, stop naming context ids as
descriptor pool indecies.

While at it, add a bunch of missing line feeds to some error messages.

[Intel-gfx] [PATCH v2 7/8] drm/i915/guc: Drop obsolete H2G definitions

[John.C.Harrison]

From: John Harrison <John.C.Harrison@Intel.com>

The CTB registration process changed significantly a while back using
a single KLV based H2G. So drop the original and now obsolete H2G
definitions.
