(cherry picked from commit 55c262898a)
Whenever we use a BO in a batch, we need to find its corresponding exec
list entry, either to a) record that it's been used, b) update whether
it's being written, c) check for cross-batch implicit dependencies.
bo->index exists to accelerate these lookups. If a BO is used multiple
times by a batch, bo->index is its location in the list. Because the
field is global, and a BO can in theory be used concurrently by multiple
contexts, we need to double-check whether it's still there. If not, we
fall back to a linear search of all BOs in the list, looking to see if
our index was simply wrong (but presumably right for another context).
However, there's one glaringly obvious case that we missed here. If
bo->index is -1, then it's wrong for /all/ contexts, and in fact implies
that said BO has never been added to any exec list, ever. This is quite
common in fact: a new BO, never been used before, say from the BO cache,
or streaming uploaders, gets used for the first time.
In this case we can simply conclude that it's not in the list and skip
the linear walk through all buffers referenced by the batch.

(cherry picked from commit d55b5d4af5)
The initial logic was to remember the place were SPI_SHADER_PGM_LO_*
are written, then assume that we can get the register offset because
the sequence would always be:
PKT3_SET_SH_REG
SPI_SHADER_PGM_LO_* register offset
VA low 32 bits value <- reg_va_low_idx
The problem is that this sequence isn't guaranteed, for instance we
can get this instead:
0 c0067600 |
1 00000046 |
2 003ffffd | SPI_SHADER_PGM_RSRC3_VS
3 00000020 | SPI_SHADER_LATE_ALLOC_VS
4 * 00002080 | SPI_SHADER_PGM_LO_VS
5 00000080 | SPI_SHADER_PGM_HI_VS
So the assert in si_state_draw.cpp would fail as well as the VA
update logic.
So instead remember which the SPI_SHADER_PGM_LO_* offset, and the low
32 bits of the VA in si_update_shaders.

(cherry picked from commit 07ad6fd34a)
When `MESA_LOADER_DRIVER_OVERRIDE` is set to `zink` and the display
initialization fails, fallback to software rendering.
The error was reported in #10123 and it can be reproduced with:
$ MESA_LOADER_DRIVER_OVERRIDE=zink eglinfo
`eglinfo` would crash in `dri2_display_release()` because of
`assert(dri2_dpy->ref_count > 0)`.
After bisecting the error to commit 8cd44b8843 ("egl/glx: add
autoloading for zink"), I found out that, before this change, the
display was set to initialized even when `_eglDriver.Initialize(disp)`
failed:
disp->Options.Zink = env && !strcmp(env, "zink");
// disp->Options.Zink is true
if (!_eglDriver.Initialize(disp)) {
[...]
// Zink initialization has failed at this point
// However, success is set to true:
bool success = disp->Options.Zink;
if (!disp->Options.Zink && !getenv("GALLIUM_DRIVER")) {
[...]
}
// Software initialization is ignored because success is true
if (!success) {
[...]
}
}
// The display is set as initialized even though it shouldn't
disp->Initialized = EGL_TRUE;

(cherry picked from commit d913927fe9)
Chain stored modifiers point to the mapping of the current feedback
shmem of the surface. The surface tracked feedback mapping will be gone
and replaced with new mapping during surface_dmabuf_feedback_done. There
are two issues here:
1. One issue is that the existing mapping is closed before been used to
compare against new modifiers in sets_of_modifiers_are_the_same.
2. The other issue is that when the chain is still optimal, the chain
persists while the mapping is still replaced with the one from the
new format table shmem.
This change makes a deep copy of the modifiers to store in the chain to
ensure the modifiers used for the current chain are immutable through
the chain lifecycle.

Got a error state on DG2 with a jump to secondary. The secondary is
empty and padded with MI_NOOPs to workaround the CS prefetching.
According to the error state, the return jump address from the
secondary to the primary is 0x0. The ACTHD register value is 0x10, so
it seems that the command streamer indeed jumped to 0x0 and hanged on
a few dwords after that.
The return address should have been set edited by a previous
MI_STORE_DATA_IMM instruction. So it appears it did not complete in
time for the command stream to catch it. On Gfx12+ this can happend if
we do not set ForceWriteCompletionCheck.
This change also takes the opportunity to remove the padding MI_NOOPs
at the end of secondaries on Gfx12+ by using disabling the prefetching
just before jumping into secondaries and reenabling it at the
beginning of each secondary.
