[igt-dev] [PATCH i-g-t v3 0/7] Make gpgpu fill tests libdrm independent

[igt-dev] [PATCH i-g-t v3 0/7] Make gpgpu fill tests libdrm independent

[Zbigniew Kempczyński]

I've introduced intel_bb which is very simplified version of libdrm
powered intel_batchbuffer. Currently it supports simple relocation
but it is enough to cover all gpgpu fill needs. Other (fenced) 
relocation will be added when I will have to face with such pipelines /
batchbuffers.

As commands created in gpu_cmds.c are coupled more than I thought on 
the beginning (media fill also use them) "_v2" suffix was introduced.
When all tests will be rewritten to "_v2" old functions can be removed
and "_v2" can be deleted.

v2: changes according to the review:
    - make intel_bb api more consistent and universal
    - add intel_bb api documentation
    - add alignment field in buf_ops buffer initalization for linear
      buffers
v3: changes:
    - add all gens pipelines
    - fix compiling issues on non-x86 archs
    - add ctx (suggested by knr)

Zbigniew Kempczyński (7):
  lib/intel_bufops: Add bufops reference and relaxate stride requirement
  lib/rendercopy_bufmgr: Pass alignment during buffer initialization
  lib/intel_batchbuffer: Introduce intel_bb
  lib/gpu_cmds: Add gpgpu pipeline functions based on intel_bb
  lib/gpgpu_fill: libdrm-free gpgpu pipeline creation
  lib/intel_batchbuffer: Introduce temporary igt_fillfunc_v2_t
  tests/gem_gpgpu_fill: Remove libdrm dependency

[igt-dev] [PATCH i-g-t v3 1/7] lib/intel_bufops: Add bufops reference and relaxate stride requirement

[Zbigniew Kempczyński]

Add bufops reference to intel_buf to allow acquire drm fd against which
buffer was created.

Relax stride limitation for intel_buf for non-tiled buffers.

v2: add alignment and ensure it is dword sized for linear buffers

[igt-dev] [PATCH i-g-t v3 2/7] lib/rendercopy_bufmgr: Pass alignment during buffer initialization

[Zbigniew Kempczyński]

For linear buffer buf_ops currently was extended to align the stride
so we need to update the call.

[igt-dev] [PATCH i-g-t v3 4/7] lib/gpu_cmds: Add gpgpu pipeline functions based on intel_bb

[Zbigniew Kempczyński]

Add no-libdrm functions which will replace libdrm version in the
final version.

[igt-dev] [PATCH i-g-t v3 6/7] lib/intel_batchbuffer: Introduce temporary igt_fillfunc_v2_t

[Zbigniew Kempczyński]

gem_gpgpu_fill test is spread over different generations (gen >= 7)
so some transitional state is required until all gens will be
rewritten to new intel_bb code without libdrm dependency.

So, let's define new igt_fillfunc_v2_t to be new fill function.

[igt-dev] [PATCH i-g-t v3 7/7] tests/gem_gpgpu_fill: Remove libdrm dependency

[Zbigniew Kempczyński]

Gpgpu pipeline creation is a little bit coupled (some functions
are used in other gens) so providing "v2" version of the same
functions is necessary unless former will have full replacement
(media fill also uses same functions).

So gpgpu fill prefers now "newer" version of the same pipeline
creation which is libdrm-free.

128 is for y-tiling, 512 for x-tiling; and of course older gen varies.

if (tiling) {
	if (gen < 3)
		tile_width = 128;
	else if (IS_ALV || IS_GDG || tiling == X)
		tile_width = 512;
	else
		tile_width = 128;
}

So if you need a work anywhere value, 512.

free(NULL) is safe.

If you get into the CCS directory management (which we will for
rendercopy), we will need to take note of EXEC_OBJECT_PINNED. And you
may as well pass the EXEC_OBJECT_WRITE flag at this time. In short, you
might as well start off by passing flags.

The canonical source is execobj[].offset. The kernel always updates the
returned execobj[] with the correct information, but the reloc[] array
may be told a lie to force a relocation on the next pass.

The rule is address in batch matches that of reloc[].presumed_offset
that matches execobj[].offset. The latter being the linchpin.

So what we tend to end up doing is just adding the batch whenever it
makes sense then swapping it at the end. You could insist upon having
I915_EXEC_BATCH_FIRST so that you can put into the execobj[] at creation
time, but doing a swap() at submit is easy as well.

Really tempted to say insertion sort and bsearch. I wonder if we have
enough objects for that to be worthwhile. Brb, off to try that idea out
in iris....
