panvk-bifrost campaigns (r1..r4 Vulkan compositor + r5.video1 Vulkan
video decode) shipped before this repo existed; the deliverable
patches live in marfrit-packages, but the reasoning chain, phase docs,
and source-state evidence lived only in local working trees on the
development host.
This retrofit imports:
- mesa-panvk-bifrost/ — r1..r4 era phase docs (iter1..iter18)
(libmali stub blobs at iter18/blob/ excluded
— 109MB of RE artifacts replaced with a README
pointer)
- mesa-panvk-bifrost-video/ — sibling campaign phase docs + probe
- evidence/ — frozen .tgz source snapshots at each milestone
(basis for the 0005 patch diff generation)
Future iterations should branch off here from day one, so each iter is
a commit rather than a snapshot. See [[feedback-session-local-process-pins]]
for the process drift this retrofit closes.
Total: 1.9 MB across 124 files.

// iter3 gl_FragCoord-encoded fragment shader.

// For each pixel at integer position (x, y):
|
|
// R = x / 255 -> byte x (UNORM)
|
|
// G = y / 255 -> byte y (UNORM)
|
|
// B = 0x80 -> sentinel proving the frag shader executed
|
|
// A = 0xff -> opaque
|
|
// Readback: pixel at (col, row) should be 0xff80(row)(col) LE.
