Pull drm updates from Dave Airlie:
 "There are two external interactions of note, the msm tree pull in some
  opp tree, hopefully the opp tree arrives from the same git tree
  however it normally does.

  by drm, so is merging through my tree. This will hopefully help open
  up gpu cgroup usage a bit more and move us forward.

drm/xe: introduce xe_gt_reset and xe_gt_wait_for_reset

Add synchronous version gt reset as there are few places where it
is expected.
Also add a wait helper to wait until gt reset is done.

drm/xe: fix the ERR_PTR() returned on failure to allocate tiny pt

2024-12-12T15:57:28+00:00

Running coccinelle spatch gave the following warning:

./drivers/gpu/drm/xe/tests/xe_migrate.c:226:5-11: inconsistent IS_ERR
and PTR_ERR on line 228.

The code reports PTR_ERR(pt) when IS_ERR(tiny) is checked:

→ 211  pt = xe_bo_create_pin_map(xe, tile, m->q->vm, XE_PAGE_SIZE,
  212                            ttm_bo_type_kernel,
  213                            XE_BO_FLAG_VRAM_IF_DGFX(tile) |
  214                            XE_BO_FLAG_PINNED);
  215  if (IS_ERR(pt)) {
  216          KUNIT_FAIL(test, "Failed to allocate fake pt: %li\n",
  217                     PTR_ERR(pt));
  218          goto free_big;
  219  }
  220
  221  tiny = xe_bo_create_pin_map(xe, tile, m->q->vm,
→ 222                              2 * SZ_4K,
  223                              ttm_bo_type_kernel,
  224                              XE_BO_FLAG_VRAM_IF_DGFX(tile) |
  225                              XE_BO_FLAG_PINNED);
→ 226  if (IS_ERR(tiny)) {
→ 227          KUNIT_FAIL(test, "Failed to allocate fake pt: %li\n",
→ 228                     PTR_ERR(pt));
  229          goto free_pt;
  230  }

Now, the IS_ERR(tiny) and the corresponding PTR_ERR(pt) do not match.

Returning PTR_ERR(tiny), as the last failed function call, seems logical.

module: Convert symbol namespace to string literal

2024-12-02T19:34:44+00:00

Clean up the existing export namespace code along the same lines of
commit 33def8498fdd ("treewide: Convert macro and uses of __section(foo)
to __section("foo")") and for the same reason, it is not desired for the
namespace argument to be a macro expansion itself.
