[igt-dev] [PATCH i-g-t 0/8] Adjust IGT for upstream API clean-ups

[igt-dev] [PATCH i-g-t 0/8] Adjust IGT for upstream API clean-ups

[Jason Ekstrand]

I'm trying to remove some unused APIs from upstream i915.  This i-g-t
series updates tests in accordance with those removals.  For a few things,
it simply deletes tests which test explicitly for that feature.  For
cloning, we do actually use that for a bunch of stuff today so I just
implement the two clones we care about (engines and VMs) directly with
getparam and a create setparam.

Jason Ekstrand (8):
  tests/i915: Drop gem_ctx_ringsize
  tests/i915/gem_exec_balancer: Drop the ringsize subtest
  tests/i915/gem_exec_endless: Stop setting the ring size
  tests/i915/gem_ctx_param: Drop the zeromap subtests
  tests/i915: Drop gem_ctx_clone
  tests/i915/gem_ctx_create: Stop cloning engines
  tests/i915/gem_ctx_persistence: Drop the clone test
  lib/i915/gem_context: Implement VM and engine cloning manually

[igt-dev] [PATCH i-g-t 1/8] tests/i915: Drop gem_ctx_ringsize

[Jason Ekstrand]

I915_CONTEXT_PARAM_RINGSIZE is being removed from upstream i915 because
it's never been used by any userspace other than IGT.

Your forgot Makefile.sources. Yes we still have some autotools left for
test building. With that fixed and the sob line fixed.

Lots of MI_SEMAPHORE in this tests, looks a bit like something that is
probably not a valid usecase for legacy dma_fence execbuf with
end-of-batch dma_fence semantics. But didn't look too closely.

Up to this patch, with sob added:

I think a bit more history here would be nice: Userspace did exist once in
the form of patches for beignet, but never landed. This is probably one of
the features that originally have been driven by the geod stack, and as
soon as the kernel side landed, no one cared.

[igt-dev] [PATCH i-g-t 6/8] tests/i915/gem_ctx_create: Stop cloning engines

[Jason Ekstrand]

There's no reason to clone engines here, especially when context 0 is
just a default context so creating a new context will have the same
engines as context 0.

[igt-dev] [PATCH i-g-t 8/8] lib/i915/gem_context: Implement VM and engine cloning manually

[Jason Ekstrand]

We're going to be deleting the CONTEXT_CLONE API since IGT is the only
userspace to ever use it.  There are only two bits of this API that IGT
uses in interesting ways so implement them as create params instead of
cloning.

Re: [igt-dev] [PATCH i-g-t 8/8] lib/i915/gem_context: Implement VM and engine cloning manually

I think this works, only major concern I have: Do we have a userspace that
uses getparam with the engine param? vm_id I know we need to keep working
in some form, but engines I've not seen. And keeping the getparam working
just for igt isn't much better than keeping clone working.

Maybe we need to limit this to just VM sharing, and open code the other
users in the test directly.

Once that's sorted: For at least the functions you're touching, can you
pls add gtkdoc in the libraries and wire it up for the doc build? I know
in the past especially gem igt libarary code has been extremely lacking on
this, but we need to start somewhere with better test code. This is as
good a place as any. For that perhaps check with Petri and Zbyscek on irc
how to get the doc build going, it's a bit an adventure unfortunately.

Also I do wonder how much more fallout we'll see once we start to lock
down the contexts after the first execbuf.

Also needs sob.

At least in the kernel we tend to make these enums so you have a place to
put docs, but not sure about igt.

Not sure.  I kind-of doubt it.  Also, the getparam has some pretty
ugly corners.  If the client hasn't explicitly set any engines, it
doesn't return any so there's no "get me the default".  This makes me
suspect the answer is "no".

There are a few tests which use the engine clone for a useful purpose.
It could be plumbed through but it'd be semi-annoying.  That said,
it's only 1-2 tests so I could probably do that easily enough.

igt also uses sob/developer certificate, so need to add those. I wanted to
otherwise review this today but just didn't get around to it :-/

Hopefully tomorrow.

[igt-dev] [PATCH i-g-t 0/9] Adjust IGT for upstream API clean-ups (v2)

[Jason Ekstrand]

I'm trying to remove some unused APIs from upstream i915.  This i-g-t
series updates tests in accordance with those removals.  For a few things,
it simply deletes tests which test explicitly for that feature.  For
cloning, we do actually use that for a bunch of stuff today so I just
implement the two clones we care about (engines and VMs) directly with
getparam and a create setparam.

Jason Ekstrand (9):

  tests/i915/gem_exec_balancer: Drop the ringsize subtest
  tests/i915/gem_exec_endless: Stop setting the ring size

[igt-dev] [PATCH i-g-t 1/9] tests/i915: Drop gem_ctx_ringsize

[Jason Ekstrand]

I915_CONTEXT_PARAM_RINGSIZE is being removed from upstream i915 because
it's never been used by any userspace other than IGT.

[igt-dev] [PATCH i-g-t 4/9] tests/i915/gem_ctx_param: Drop the zeromap subtests

[Jason Ekstrand]

The idea behind this param is to support OpenCL drivers with relocations
because OpenCL reserves 0x0 for NULL and, if we placed memory there, it
would confuse CL kernels.  It was originally sent out as part of a patch
series including libdrm [1] and Beignet [2] support.  However, the
libdrm and Beignet patches never landed in their respective upstream
projects so this API has never been used.  It's never been used in Mesa
or any other driver, either.

This means that these IGT tests are the only userspace for NO_ZEROMAP
which has ever really existed.  Let's drop them and drop support from
i915 as well.

[igt-dev] [PATCH i-g-t 6/9] tests/i915/gem_ctx_create: Stop cloning engines

[Jason Ekstrand]

There's no reason to clone engines here, especially when context 0 is
just a default context so creating a new context will have the same
engines as context 0.

[igt-dev] [PATCH i-g-t 9/9] lib/i915/gem_context: Implement VM and engine cloning manually (v2)

[Jason Ekstrand]

We're going to be deleting the CONTEXT_CLONE API since IGT is the only
userspace to ever use it.  There are only two bits of this API that IGT
uses in interesting ways so implement them as create params instead of
cloning.

v2 (Jason Ekstrand):
 - Fix our usage of the param struct for VM cloning
 - Handle the case of zero user engines properly
 - Assert that all cloned engines are physical, not virtual

[igt-dev] [PATCH i-g-t 9/9] lib/i915/gem_context: Implement VM and engine cloning manually (v3)

[Jason Ekstrand]

We're going to be deleting the CONTEXT_CLONE API since IGT is the only
userspace to ever use it.  There are only two bits of this API that IGT
uses in interesting ways so implement them as create params instead of
cloning.

v2 (Jason Ekstrand):
 - Fix our usage of the param struct for VM cloning
 - Handle the case of zero user engines properly
 - Assert that all cloned engines are physical, not virtual

v3 (Jason Ekstrand):
 - Drop gem_has_context_clone()
 - Add docs for [__]gem_context_clone()

[igt-dev] [PATCH i-g-t 9/9] lib/i915/gem_context: Implement VM and engine cloning manually (v3)

[Jason Ekstrand]

We're going to be deleting the CONTEXT_CLONE API since IGT is the only
userspace to ever use it.  There are only two bits of this API that IGT
uses in interesting ways so implement them as create params instead of
cloning.

v2 (Jason Ekstrand):
 - Fix our usage of the param struct for VM cloning
 - Handle the case of zero user engines properly
 - Assert that all cloned engines are physical, not virtual

v3 (Jason Ekstrand):
 - Drop gem_has_context_clone()
 - Add docs for [__]gem_context_clone()

[igt-dev] [PATCH i-g-t 0/9] Adjust IGT for upstream API clean-ups (v2)

[Jason Ekstrand]

I'm trying to remove some unused APIs from upstream i915.  This i-g-t
series updates tests in accordance with those removals.  For a few things,
it simply deletes tests which test explicitly for that feature.  For
cloning, we do actually use that for a bunch of stuff today so I just
implement the two clones we care about (engines and VMs) directly with
getparam and a create setparam.

Jason Ekstrand (9):
  tests/i915: Drop gem_ctx_ringsize
  tests/i915/gem_exec_balancer: Drop the ringsize subtest
  tests/i915/gem_exec_endless: Stop setting the ring size
  tests/i915/gem_ctx_param: Drop the zeromap subtests
  tests/i915: Drop gem_ctx_clone
  tests/i915/gem_ctx_create: Stop cloning engines
  tests/i915/gem_ctx_persistence: Drop the clone test
  tests/i915/gem_exec_balancer: Stop cloning engines
  lib/i915/gem_context: Implement VM and engine cloning manually (v2)

[igt-dev] [PATCH i-g-t 4/9] tests/i915/gem_ctx_param: Drop the zeromap subtests

[Jason Ekstrand]

The idea behind this param is to support OpenCL drivers with relocations
because OpenCL reserves 0x0 for NULL and, if we placed memory there, it
would confuse CL kernels.  It was originally sent out as part of a patch
series including libdrm [1] and Beignet [2] support.  However, the
libdrm and Beignet patches never landed in their respective upstream
projects so this API has never been used.  It's never been used in Mesa
or any other driver, either.

This means that these IGT tests are the only userspace for NO_ZEROMAP
which has ever really existed.  Let's drop them and drop support from
i915 as well.

[igt-dev] [PATCH i-g-t 6/9] tests/i915/gem_ctx_create: Stop cloning engines

[Jason Ekstrand]

There's no reason to clone engines here, especially when context 0 is
just a default context so creating a new context will have the same
engines as context 0.

We're going to be deleting the CONTEXT_CLONE API since IGT is the only
userspace to ever use it.  Drop the tests for it.

[igt-dev] [PATCH i-g-t 9/9] lib/i915/gem_context: Implement VM and engine cloning manually (v3)

[Jason Ekstrand]

We're going to be deleting the CONTEXT_CLONE API since IGT is the only
userspace to ever use it.  There are only two bits of this API that IGT
uses in interesting ways so implement them as create params instead of
cloning.

v2 (Jason Ekstrand):
 - Fix our usage of the param struct for VM cloning
 - Handle the case of zero user engines properly
 - Assert that all cloned engines are physical, not virtual

v3 (Jason Ekstrand):
 - Drop gem_has_context_clone()
 - Add docs for [__]gem_context_clone()

[igt-dev] [PATCH i-g-t 0/9] Adjust IGT for upstream API clean-ups

[Jason Ekstrand]

I'm trying to remove some unused APIs from upstream i915.  This i-g-t
series updates tests in accordance with those removals.  For a few things,
it simply deletes tests which test explicitly for that feature.  For
cloning, we do actually use that for a bunch of stuff today so I just
implement the two clones we care about (engines and VMs) directly with
getparam and a create setparam.

Sorry about so many re-sends.  I'm still trying to figure out how to make
patchwork like my patches.  I think this one should finally do the trick.

Jason Ekstrand (9):
  tests/i915: Drop gem_ctx_ringsize
  tests/i915/gem_exec_balancer: Drop the ringsize subtest
  tests/i915/gem_exec_endless: Stop setting the ring size
  tests/i915/gem_ctx_param: Drop the zeromap subtests
  tests/i915: Drop gem_ctx_clone
  tests/i915/gem_ctx_create: Stop cloning engines
  tests/i915/gem_ctx_persistence: Drop the clone test
  tests/i915/gem_exec_balancer: Stop cloning engines
  lib/i915/gem_context: Implement VM and engine cloning manually (v3)

[igt-dev] [PATCH i-g-t 6/9] tests/i915/gem_ctx_create: Stop cloning engines

[Jason Ekstrand]

There's no reason to clone engines here, especially when context 0 is
just a default context so creating a new context will have the same
engines as context 0.
