[igt-dev] [PATCH i-g-t v8 00/17] Integrate intel-bb with Xe

[Zbigniew Kempczyński]

Series touches intel-bb + intel-buf which are rendercopy, gpgpu fill and
media fill facilities. Exercise both paths on CI (i915 and xe) to check
there's no regression in common part.

v2: fix allocator issue
v3: address review comments (Kamil)
v4: address review comments (Christoph)
v5: - address review comments (Kamil)
    - add region awareness in bufops (Zbigniew)
v6: alter igt_draw and kms_big_fb to be region aware (Zbigniew)
v7: - separate random->reloc docs fix patch (Kamil)
    - reorganize driver (i915/xe) blocks (Kamil)
    - fix xe_bound issue for single buffer (Zbigniew)
v8: separate change for RELOC in reset path (Christoph)

[Zbigniew Kempczyński]

For easier iterate over memory regions and produce dynamic subtests
add xe_region_name() helper.

As Xe requires buffer size alignment during creating bo add
xe_min_page_size() helper.

[igt-dev] [PATCH i-g-t v8 04/17] lib/intel_allocator: Add allocator support for Xe

[Zbigniew Kempczyński]

Start supporting va range configuration for xe allocator.

During opening allocator has to be aware of vm range (start and end).
i915 driver doesn't expose vm range information so those variables
have to be detected. In xe driver we get information of va size from
the kernel query so va end can be directly configured. At the moment
there's no autodetection of va start for xe what might need to be
address in the future if for some reason lower offsets might not be
in use.

[igt-dev] [PATCH i-g-t v8 05/17] lib/drmtest: Add driver enum for i915/xe

[Zbigniew Kempczyński]

Library code like intel-bb and intel-buf which requires adoption
to handle both drivers should store driver on which fd they are
working on instead of calling costful is_i915/xe_device() helper.

Introduce intel_driver enum which will be used on library code
adoption to Xe.

Extend bufops to support Xe:
 - change region to 64bit region mask,
 - add initialization helper (full) which allows passing handle,

 - mapping functions (read + write) selects driver specific mapping

[igt-dev] [PATCH i-g-t v8 07/17] lib/intel_batchbuffer: Rename i915 -> fd as preparation step for xe

[Zbigniew Kempczyński]

Until now intel-bb was designed to handle i915 (relocations and
softpinning). We want to reuse it also for xe as softpinning
which requires allocator also unblocks this for vm_bind used
in xe.

This is preparation step which stops using i915 as internal fd
to avoid confusion.

[igt-dev] [PATCH i-g-t v8 08/17] lib/intel_batchbuffer: Reacquire offset for reloc allocator in reset path

[Zbigniew Kempczyński]

On reset path we recreate bo for batch (to avoid stalls) so we should
reacquire the offset too. At the moment simple allocator will return
same offset (so unfortunately we'll stall), but for reloc allocator
we'll get new one (so we avoid stall).

I've noticed this is missing during xe_intel_bb test, where on reloc
I noticed unexpected result (direct consequence of using same offset
which pointed to old batch, not new one).

[igt-dev] [PATCH i-g-t v8 09/17] lib/intel_batchbuffer: Update intel-bb docs

[Zbigniew Kempczyński]

After RANDOM pseudo-allocator was removed and RELOC allocator becomed
stateful docs stays intact and documents old code. Fix this before
adding xe code.

Hi Zbigniew,

It just came to my mind that if you dedicate a patch for 
'__intel_bb_create' docs update, you may as well add missing description 
for 'start', 'end' and 'strategy' parameters. But it's optional, it can 
wait for another day.

Anyway:

[igt-dev] [PATCH i-g-t v8 10/17] lib/intel_batchbuffer: Add Xe support in intel-bb

[Zbigniew Kempczyński]

Intention of creating intel-bb was to replace libdrm for i915.
Due to many code relies on it (kms for example) most rational way
is to extend and add Xe path to it.

[igt-dev] [PATCH i-g-t v8 11/17] tests/xe_intel_bb: Check if intel-bb Xe support correctness

[Zbigniew Kempczyński]

As we're reusing intel-bb for Xe we need to check it behaves correctly
for buffer handling and submission.

Re: [igt-dev] [PATCH i-g-t v8 11/17] tests/xe_intel_bb: Check if intel-bb Xe support correctness

imho it will be more clear to state that you added new test here,
so instead of:

tests/xe_intel_bb: Check if intel-bb Xe support correctness

this will be better:

tests/xe_intel_bb: add new test for intel-bb on Xe platform

Then you describe rationale in message. It is up to you if you
would like to change this, so with or without it:

[igt-dev] [PATCH i-g-t v8 13/17] lib/gpgpu_fill: Use RENDER engine flag to work on Xe

[Zbigniew Kempczyński]

Using I915_EXEC_DEFAULT works fine for i915 selecting appropriate
command streamer. Unfortunately this cannot be used on Xe as it
requires explicit engine selection. Submitting gpgpu work on
render is fine so change to I915_EXEC_RENDER doesn't break i915
and allows run on valid engine on Xe.

[igt-dev] [PATCH i-g-t v8 15/17] lib/igt_fb: For xe assume vram is used on discrete

[Zbigniew Kempczyński]

Assume fb bo's were created on vram on discrete, otherwise use system
memory.

[igt-dev] [PATCH i-g-t v8 16/17] lib/igt_draw: Pass region while building intel_buf from flink

[Zbigniew Kempczyński]

For i915 region doesn't matter but for xe we need to be more strict and
region aware. This is related to size and alignment constraints. As we
don't have information about flink buffer origin let's assume region
is vram if possible, otherwise choose system region.

[Zbigniew Kempczyński]

For discrete framebuffer reside on vram/device memory and for
