ir3: Add gen4 new subgroup instructions
* getlast.w8 #4 - Perform jump for the first (CLUSTER_SIZE-1) fibers in a subgroup * brcst.active.w8 - necessary to implement arithmetic subgroup operations with prefix sum. * quad_shuffle.brcst - subgroupQuadBroadcast * quad_shuffle.horiz - subgroupQuadSwapHorizontal * quad_shuffle.vert - subgroupQuadSwapVertical * quad_shuffle.diag - subgroupQuadSwapDiagonal * getfiberid - gl_SubgroupID Signed-off-by: Danylo Piliaiev <dpiliaiev@igalia.com> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/13817>

The subgroup is divided into (subgroup_size / CLUSTER_SIZE)
|
||||
clusters. For each cluster brcst.active.w does:
|
||||
|
||||
Given a cluster of fibers f_0, f_1, ..., f_{CLUSTER_SIZE-1} brcst
|
||||
broadcasts the SRC value from the fiber f_{CLUSTER_SIZE/2-1}
|
||||
to fibers f_{CLUSTER_SIZE/2}, ..., f_{CLUSTER_SIZE-1}. The DST reg
|
||||
in other fibers is unaffected. If fiber f_{CLUSTER_SIZE/2-1} is
|
||||
inactive the value to broadcast is taken from lower fibers
|
||||
f_{CLUSTER_SIZE/2-2}, f_{CLUSTER_SIZE/2-3}, ...
|
||||
If all fibers f_0, f_1, ..., f_{CLUSTER_SIZE/2-1} are inactive
|
||||
the DST reg remains unchanged for all fibers.
|
||||
|
||||
It is necessary in order to implement arithmetic subgroup
|
||||
operations with prefix sum (https://en.wikipedia.org/wiki/Prefix_sum).
|
||||
|
||||
For brcst.active.w8 without inactive fibers:
|
||||
Fiber | 0 1 2 3 4 5 6 7 | 8 9 10 11 12 13 14 15
|
||||
SRC | s0 s1 s2 s3 ... s7 | s8 ... s11 ... s15
|
||||
DST_before | d0 d1 ... d7 | d8 ... d15
|
||||
DST_after | d0 d1 d2 d3 s3 s3 s3 s3 | d8 ... d11 s11 s11 s11 s11
|
||||
|
||||
If fibers 2 and 3 are inactive:
|
||||
Fiber | 0 1 X X 4 5 6 7 | ...
|
||||
SRC | s0 s1 X X ... s7 | ...
|
||||
DST_before | d0 d1 ... d7 | ...
|
||||
DST_after | d0 d1 X X s1 s1 s1 s1 | ...
