Core dump support relies on debugger related KFD ioctl which have been
introduced in version 1.13 of the interface. However, the code checks
for KFD_IOCTL_MINOR_VERSION (currently 17), making it impossible to
produce core dumps when using some drivers that should support it.
Update the CHECK_KFD_MINOR_VERSION calls in the debugger related ioctl
wrappers and look for KFD 1.13 or above.

A recent patch introduced a build failure when building with Clang:
[ 65%] Building CXX object runtime/hsa-runtime/CMakeFiles/hsa-runtime64.dir/libamdhsacode/amd_core_dump.cpp.o
[…]/runtime/hsa-runtime/libamdhsacode/amd_core_dump.cpp:271:29: error: arithmetic on a pointer to void
271 | read = pread(fd_, buf + done, buf_size - done,

1 error generated.
This patch fixes this by making sure the "void *" pointer is converting
to "char *" before doing arithmetic on it.

The current trap handler has 2 limitations:
1) If it receives a HOST_TRAP, it clears the corresponding bit
and notifies the host, when it should not.
2) When it is entered because of a debug trap (s_trap 3) and the
debugger is not attached, it returns unconditionally. However,
if another exception is reported at the same time as the trap
handler is entered for the debug trap (a memory violation for
example), that other exception ends-up being ignored.
This patch addresses both of those issues. It makes it so host traps
and debug traps are ignored when necessary. If any other exception is
reported to the wave, we halt the wave and notify the host, and if no
other exception is reported (i.e. we entered the trap handler because of
host trap or debug trap), we return to shader code.
Other minor defects are also fixed during this refactor:
- Fixed SQ_WAVE_EXCP_FLAG_PRIV_XNACK_ERROR_SHIFT which had an incorrect
value
- Host traps can be sent at any time, including after we have halted a
wave. In such case, the old approach would have:
1) cleared the trap ID saved in ttmp6
2) clobbered ttmp10 where part of the actual wave's PC is saved.

This fixes an issue for missing HW events when out of HW events.
We cannot determine whether a HW event has occurred unless we call the
underlying drivers with hsaKmtWaitOnMultipleEvents_Ext. Previous logic
in Signal::WaitAny would switch to ACTIVE_WAIT state if we run out of
hardware events (signal->EopEvent() == NULL) and this would cause the
hsaKmtWaitOnMultipleEvents_Ext call to be skipped. But also, when we
have some signals without hardware events, calling
hsaKmtWaitOnMultipleEvents_Ext with a timeout of 0 so that we can poll
for remaining signals adds overhead with an IOCTL call and may cause
extra delay. Separating AsyncEventLoop into two separate threads so
that:
1. We can have a new Signal::WaitAnyExceptions to wait for HW events
This function can be simpler as it does not have to perform all the
timer calculations because it is expected to be always waiting on
hsaKmtWaitOnMultipleEvents_Ext through the lifetime of a process.
2. Signal::WaitAny does not need to have extra code to check for HW
exceptions as it only needs to handle HSA_EVENTTYPE_SIGNAL events. It
can also skip the calls to hsaKmtWaitOnMultipleEvents_Ext if needed.

If user application tries to free memory that is currently being used by
the underlying HW device, the hsaKmtFreeMemory function call will fail.
This would be caused by an incorrect call by the user application. A
system memory error is raised and the user application is expected to
abort when this happens.
Note: This leaves the allocation_map_ table in an inconsistent state as
this address entry is removed from it while the pointer is not actually
free'd. But re-organising the FreeMemory() function would require the
memory_lock_ to be held for much longer and may affect performance.
Since this is a very unlikely and invalid use case, we prefer to leave
the FreeMemory() function as is.

causes unnecessary error message because both places try to create a
coredump file with the same name.

It is possible for the runtime to receive an interrupt while trying to
access VRAM data using /proc/self/mem. In such case, pread(2) would
return -1 and set errno to -EINTR. This is not an error case, the
pread(2) call just need to be restarted, however current implementation
would tread it as an error.
This patch changes the the implementation to correctly retry on EINTR.
While at it, this patch also handles cases where pread(2) reads less
data than originally requested.
