From: Dominik Grzegorzek <dominik.grzegorzek@intel.com>
Introduce library which simplifies testing of eu debug capability.
The library provides event log helpers together with asynchronous
abstraction for client proccess and the debugger itself.
xe_eudebug_client creates its own proccess with user's work function,
and gives machanisms to synchronize beginning of execution and event
logging.
xe_eudebug_debugger allows to attach to the given proccess, provides
asynchronous thread for event reading and introduces triggers - a
callback mechanism triggered every time subscribed event was read.

> The library provides event log helpers together with asynchronous abstraction
> for client proccess and the debugger itself.
>
> xe_eudebug_client creates its own proccess with user's work function, and
> gives machanisms to synchronize beginning of execution and event logging.
>
> xe_eudebug_debugger allows to attach to the given proccess, provides
> asynchronous thread for event reading and introduces triggers - a callback
> mechanism triggered every time subscribed event was read.

From: Mika Kuoppala <mika.kuoppala@linux.intel.com>
In some tests, we need to pause the client into a certain
stage it has setup so that debugger can then examine that
setup and crosscheck.
Add a possibility to pause client and debugger to signal
continuation.
We need to take into account that the debugger might
disappear before signaling continuation so a timeout
mechanism for all pipe token reads needs to be added.

Support metadata events in debugger library by:
- Adding metadata events to log checking functions.
- Introducing eudebug vm_bind wrapper which allows to attach debug
metadata and cookie
- Implementing xe_eudebug_client_metadata_create|destroy wrappers.

If the debugee uses user fences for synchronization, the debugger will
recieve a 'UFENCE_EVENT' and the fence won't be released untill the
debugger acks it. Note that for the fence to release, both the job
completion and debugger ack are required. Add a library function
to ack user fences.

The debugger now uses a dedicated sysfs entry:
/sys/class/drm/card<N>/device/enable_eudebug
to toggle the debugger on/off. This change adds helper functons for
toggling the debugger.

Validate eu debug resource discovery in a pretty cruel way.
Add subtests:
1) discovery-race - spawns N client proccesses, which create
N+N*N resources each, then it creates M debugger
threads competing for an access to the client proccess. After
successful attach, with probability of 0.5 read and assert
discovered resources, immediately detach otherwise.
2) discovery-empty[|-clients] - same as 1#, but destroy
resources in flight (explicetly or by closing the client).
Expect the last discovery not sending any events.
Currently N = 4, M = 3.

Add tests which exercise setting debug metadata and correctness
of events received by currently attached debugger.
Extended the attach-debug-metadata so that it has multimple metadatas per
bind. (Maciej)

From now on the debugger is disabled by default so it is required
to enable the debugger before using it. This change addresses that

In some tests, we need to pause the debugger at a certain stage as
the point at which the client performs certain activities, determines
the executed code path in the driver.
Add a possibility to pause debugger and to signal continuation by
the client.

Extend vm-bind testing by adding variations of existing subtests,
that exercise the eu debugger's discovery mechanism, by attaching
after relevant vm-bind operations were performed by the client.

From: Maciej Patelczyk <maciej.patelczyk@intel.com>
Verify the connection:
* user to user
* user to root
* root to user
* user to other user
The test uses two known non-privileged users lp and mail to verify
the scenarios. Test drops root privileges to one of users if necessary.
ptrace cannot access process which is not dumpable. The default value
of this property is stored in '/proc/sys/fs/suid_dumpable'. If process
drops privileges then it gets the value from mentioned suid_dumpable.
In our case the value after switching userm, to non privileged one,
is 2 (SUID_DUMP_ROOT). Enforce it to be 1 (SUID_DUMP_USER).

exercises lseek support and also that pwrite successfully wrote the

From: Jonathan Cavitt <jonathan.cavitt@intel.com>
Extend the basic vm access tests to allow for specifying the target bo
size per bo in the bind list. The size still has to be at least the
minimum, but can be overwritten to be larger.
Make sure that the vm is unbound during bind list destroy, to avoid
overlapping vmas.

SIP is a System Instruction Pointer, which the hardware will
except/jump into when some defined event occurs, debug mode
is enabled and pipeline setup has included sip program.
Events like illegal instruction or breakpoint hit will jump
into SIP directly. Driver can also except into sip during hang
resolution and SIP can do, for example, eu thread state snapshot
before the hang resolution ends up in a hardware state reset.

From: Andrzej Hajda <andrzej.hajda@intel.com>
The tests depended on undefined behavior of GPU. Invalid instruction
provided by the test has 29th bit set, which on Xe2 causes SIP call without
providing any exception reason and AIP address, unless eudebug is enabled,
in such case breakpoint exception is signalled.
Xe2 and earlier gens are able to handle very limited set of invalid
instructions - only illegal and undefined opcodes, other errors in
instruction can cause undefined behavior.
Illegal/undefined opcode results in:
- setting illegal opcode status bit - cr0.1[28],
- calling SIP if illegal opcode bit is enabled - cr0.1[12].
cr0.1[12] can be enabled directly from the thread or by thread dispatcher
from Interface Descriptor Data provided to COMPUTE_WALKER instruction.
Re-worked tests works similar way to OOB tests:
- check if SIP is not called when exception is not enabled,
- check if SIP is called when exception is enabled from EU thread,
- check if SIP is called when exception is enabled from COMPUTE_WALKER.

Title and commit message is no longer valid here.
This commit introduces these tests. Anything that
references older version of the test should be stripped out.

From: Gwan-gyeong Mun <gwan-gyeong.mun@intel.com>
To execute in lr (long-running) mode, apart from setting
'DRM_XE_VM_CREATE_FLAG_LR_MODE' flag during vm creation, it is required
to use 'DRM_XE_SYNC_TYPE_USER_FENCE' syncs with vm_bind and xe_exec
ioctls.
Make it possible to execute batch buffers via intel_bb_exec() in lr mode
by setting the 'lr_mode' field with the supplied setter.

1# Sanity check for attention events
Introduce first online scenario (basic-attention-event)
in which we schedule EU workload with breakpoint bit set.
We expect to get eu attention and peacefully resume workload.
2# Basic coverage for eu thread control
Eu thread control is an ioctl which allows the debugger to
interfere with eu thread execution. Provide initial coverage for
that functionality Exercise interrupt-all, stopped,
and resume with bunch of different granularities.

From now on the debugger is disabled by default so it is required
to enable the debugger before using it. This change addresses that
fact by calling necessary library functions within test fixtures.

Add tdctl-parameters test that checks negative scenarios of EU_THREADS
ioctl usage.
This patch shortens the loop in run_online_client in order to avoid
hitting the timeout that caused the test to fail.

This new test performs a GPU GT forced reset on the attention event raised.
Then the test runs a new session with a workload to check if the GPU is usable.

closed and reopened on attention event. Check if the workload
is reset when there is no active debugger detected.

Add caching tests that write incrementing values to 2-page-long target
surface, poisoning the data one breakpoint before each write instruction
and restoring it when the poisoned instruction breakpoint is hit. Expect
to never see poison values in target surface.

Even though the commit is correct it probably would need to be removed in the future.
During upstream review of the Xe it was pointed out that we will need to limit
debugger functionality to only lr mode, as we depend on it.

Add subtests where we run many sessions, either on a single or
multiple tiles. Extract a macro that selects compute or render
engine from the same GT so it can be used in a helper.

Workloads could potentially be stopped on a breakpoint for a long time,
due to that eu debugger needs to disable preemption timeout to
prevent reset of such workload. Verify that.

May I ask to just divide series to library and tests part where
library changes is in few patches max, then tests in separate
patches? I've noticed through rough walk through the series
some code appears in some patches, whereas it disappears in
others. I mean I would like to review final state of the code
instead going through the history of the development eudebug
feature. Upstreaming Xe driver igts was also done in similar way
in few commits only. If you think some commit messages might
be interesting from the future perspective please keep them
during squashing.

Makes sense, I will try to squash patches for the next revision.
