We pessimistically allocate 1MB per IB when overriding cs. There could
be lots of small IBs, so we should allocate as much space as possible
for overriding.

It's useful to clear buffers at the start of sequences to view the
delta, this adds that functionality to wrbufs with a fixed clear
value of 0xDEADBEEF.

It's possible for large allocations to hit the maximum address
space size especially with a fake AS, these failures are silent
and can cause a hard to debug segfault later down the line.

We should be careful to not read past the end of any buffers when
dumping wrbufs, this clamps the size to the size of the buffer with
a warning.

d3dkmthk.h contains only non driver specific structs, private
data structs are not defined anywhere public but contain
important information for memory allocation and submissions.
Luckily only small parts of these structs are relevant for what
we want to do and most of them are not changed between calls.

While running tests, it is be useful to have non-sequenced dumps of
certain buffers to see their contents from changes in the decompiled
CS. This introduces a function gpu_read_into_file(...) for specifying
a file to read a specific GPU buffer into after replaying the CS.

Could be used in shader assembly from rddecompiler when overriding
the cmdstream.
Usage:
print r1.x, r3.z
First arguments is three consecutive registers used for internal print
needs.
Second arg is register to print.

KGSL doesn't support IOVAs being set form userspace, so as a workaround
we pre-allocate a single buffer and hope that it always starts from the
same address.

gpu_id is not decodable from chip_id in general case,
so we should use chip_id to search for fd_dev_info and get
GPU generation from that.

This adds an option to override a single cmdstream while replaying
.rd capture. Cmdstream for override is stored in the same .rd format,
where there is only one RD_CMDSTREAM_ADDR section and any amount
of buffers.
Instead of using provided .rd file, 'replay' calls external program
to generate it first, in order to be able to pass the range of
GPU addresses available for the new buffers.
Usage example:
./replay --override=13 --generator=~/cmdstream_gen

Replay command stream obtained from:
- /sys/kernel/debug/dri/0/rd
- /sys/kernel/debug/dri/0/hangrd
!!! Command stream capture should be done with ALL buffers:
- echo 1 > /sys/module/msm/parameters/rd_full
Requires kernel with MSM_INFO_SET_IOVA support.
This tool is intended for reproduction of various GPU issues:
- GPU hangs, note that command stream obtained from hangrd
may not reproduce (rarely) the hang, since the buffers are
snapshotted at the moment of the hang and not at the start
of the hanging command stream.
- TODO: Misrendering, would require marking framebuffer images
at each renderpass in order to fetch and decode them.
Code from Freedreno/Turnip is not re-used here since the relevant
pieces may introduce additional allocations which cannot be allowed
during the replay.
