d3d11:d3d11 - test_texture() fails in the TestBot VMs:

These failures don't happen on my box which has an Intel graphics card instead of QEmu's QXL graphics card. Note also that these failures still happen on my debian11 VM which has a single monitor instead of the TestBot VMs' multi-monitor setup.
So this seems to be related to the VMs QXL GPU.
Note that despite being systematic these failures could cause false positives (see bug 53212).

--- Comment #1 from François Gouget fgouget@codeweavers.com --- d3d10core:d3d10core gets a similar set of failures on the same set of test configurations:
d3d10core.c:7544: Test failed: Test 52: Got unexpected color 0xff0000ff at (0, 0). d3d10core.c:7544: Test failed: Test 52: Got unexpected color 0xff00ffff at (1, 0). d3d10core.c:7544: Test failed: Test 52: Got unexpected color 0xff00ff00 at (2, 0). d3d10core.c:7544: Test failed: Test 52: Got unexpected color 0xffffff00 at (3, 0). d3d10core.c:7544: Test failed: Test 52: Got unexpected color 0xffff0000 at (0, 1). d3d10core.c:7544: Test failed: Test 52: Got unexpected color 0xffff00ff at (1, 1). d3d10core.c:7544: Test failed: Test 52: Got unexpected color 0xff000000 at (2, 1). d3d10core.c:7544: Test failed: Test 52: Got unexpected color 0xff7f7f7f at (3, 1). d3d10core.c:7544: Test failed: Test 52: Got unexpected color 0xffffffff at (0, 2). d3d10core.c:7544: Test failed: Test 52: Got unexpected color 0xffffffff at (1, 2). d3d10core.c:7544: Test failed: Test 52: Got unexpected color 0xffffffff at (2, 2). d3d10core.c:7544: Test failed: Test 52: Got unexpected color 0xff000000 at (3, 2). d3d10core.c:7544: Test failed: Test 52: Got unexpected color 0xffffffff at (0, 3). d3d10core.c:7544: Test failed: Test 52: Got unexpected color 0xff000000 at (2, 3). d3d10core.c:7544: Test failed: Test 52: Got unexpected color 0xff000000 at (3, 3).

These failures: * Don't happen on Debian 11 + Intel / KDE * Happen on Debian 11 + QXL + single-monitor * Happen on Debian 11 + QXL + multi-monitor * Happen on Debian Testing + QXL + multi-monitor

--- Comment #2 from Zeb Figura z.figura12@gmail.com --- The given test uses a sample with a POINT mip filtering modes with explicit LOD, and specifies that LOD to be exactly 0.5. llvmpipe, when interpreting LOD, rounds to even (by default), yielding 0.0.
GL 3.2, if my reading is correct, specifies rounding to -∞ [it specifically says ceil(lod + 1/2)]. Somewhere between there and 4.6 allowance is made for a non-preferred "alternative" of rounding to +∞ (it specifically says floor(lod + 1/2)]. The latter wording is carried forward to Vulkan.
The Direct3D spec, unusually, actually gives a ruling on this: rounding towards +∞ [again, specified in terms of floor(lod + 1/2)].
radeonsi, at least, consistently rounds toward +∞. llvmpipe doesn't follow any spec consistently. That said, do we care?
