Introduce variables which can decrease number of getpid()/gettid()
calls, especially for allocator which must be aware of method
acquiring addresses.
When child is spawned using igt_fork() we can control its initialization
and prepare child_pid implicitly. Tracking child_tid requires our
intervention in the code and do something like this:
if (child_tid == -1)
child_tid = gettid()
Variable was created for using in TLS so each thread is created
with variable set to -1. This will give each thread it's own "copy"
and there's no risk to use other thread tid. For each forked child
we reassign -1 to child_tid to avoid using already set variable.

Simple allocator borrowed from Mesa adopted for IGT use.
From default we prefer an allocation from the top of vm address space
(we can catch addressing issues pro-actively). When function
intel_allocator_simple_create() is used we exclude last page as HW
tends to hang on the render engine when full 3D pipeline is executed from
the last page. For more control of vm range user can specify range using
intel_allocator_simple_create_full() (with the respect of the gtt size).

Sometimes we want to experiment with addresses so randomizing can help
us a little.

To: igt-dev
For discrete gens we have to cease of using relocations when batch
buffers are submitted to GPU. Cards which have ppgtt can use softpin
and establish addresses on our own.
We added simple allocator (taken from Mesa; works on lists) and added
random allocator to exercise batches with different addresses. All
of that works for single VM (context) so we have to add additional
layer (intel_allocator) to support multiprocessing / multithreading.
For main IGT process (also for threads created in it) intel_allocator
resolves addresses "locally", just by mutexing access to global
allocator data (allocators map). When fork() is in use children cannot
establish addresses on they own and have to contact to the thread
spawned within main IGT process. Currently SysV IPC message queue was
chosen as a communication channel between children and allocator thread.
Child calls same functions as main IGT process, only communication path
will be chosen instead of acquiring addresses locally.
v2:
Add intel_allocator_open_full() to allow user pass vm range.
Add strategy: NONE, LOW_TO_HIGH, HIGH_TO_LOW passed to allocator backend.

+ * # Intel allocator
+ *
+ * Since GPU devices driver has abandoned relocations for newer generations,
+ * we are facing the need to manage addresses in userspace. Intel allocator
+ * supply out of the box mechanisms providing correct virtual addresses.
+ * Specifically, intel_allocator is a multi-threading infrastructure wrapping
+ * a proper single-thread allocator, that can be the one of the following:
+ *
+ * * INTEL_ALLOCATOR_SIMPLE - ported from Mesa, list-based, simple allocator
+ * * INTEL_ALLOCATOR_RANDOM - stateless allocator, that provides random addresses
+ * (sometime in the future the list can grow)
+ *
+ * Usage example:
+ *
+ * |[<!-- language="c" -->
+ * struct object {
+ * uint32_t handle;
+ * uint64_t offset;
+ * uint64_t size;
+ * };
+ *
+ * struct object obj1, obj2;
+ * uint64_t ahnd, startp, endp;
+ * int fd = -1;
+ *
+ * fd = drm_open_driver(DRIVER_INTEL);
+ * ahnd = intel_allocator_open(fd, 0, INTEL_ALLOCATOR_SIMPLE);
+ *
+ * obj1.handle = gem_create(4096);
+ * obj2.handle = gem_create(4096);
+ *
+ * // Reserve hole for an object in given address.
+ * // In this example the first possible address.
+ * intel_allocator_get_address_range(ahnd, &startp, &endp);
+ * obj1.offset = startp;
+ * igt_assert(intel_allocator_reserve(ahnd, obj1.handle, 4096, startp));
+ *
+ * // Get the most suitable offset for the object. Prefered way.
+ * obj2.offset = intel_allocator_alloc(ahnd, obj2.handle, 4096, 1 << 13);
+ *
+ * ...
+ *
+ * // Reserved addresses can be only freed by unreserve.
+ * intel_allocator_unreserve(ahnd, obj1.handle, 4096, obj1.offset);
+ * intel_allocator_free(ahnd, obj2.handle);
+ *
+ * gem_close(obj1.handle);
+ * gem_close(obj2.handle);

Avoid race when stop was send to allocator thread. We wait around
100 ms to give thread chance to stop smoothly instead of removing
queue and enforcing exiting all blocked message syscalls.

When playing with multiprocess mode in allocator we're currently
using sysvipc message queues in blocking mode (request/response).
We can calculate then what is maximum depth for the queue for
requested number of children. Change alters kernel queue depth
to cover 4k users (1 is main thread and 4095 are children).
We're still prone to unlimited wait in allocator thread
(more than 4095 children successfully send the messages)
but we're going to address this later.

Validating allocator code (leaks and memory overwriting) can be done
with address sanitizer. When allocator is not working in multiprocess
mode it is easy, problems start when fork is in the game. In this
situation we need to separate preparation and starting allocator thread.

1. Buffer size from 32 -> 64 bit was changed to be consistent
with drm code.
2. Remember buffer creation size to avoid recalculation.

For some cases (fb with compression) fb size is bigger than calculated
intel_buf what lead to execbuf failure when allocator is used
along with EXEC_OBJECT_PINNED flag set for all objects.
We need to create intel_buf with size equal to fb so new function
in which we pass handle and size is required.

+ * intel-bb assumes it will work in one of two modes - with relocations or

+ * and their offsets in the internal cache and reuses in subsequent execs.
+ *
+ * 1. intel-bb with relocations
+ *
+ * Creating new intel-bb adds handle to cache implicitly and sets its address
+ * to 0. Objects added to intel-bb later also have address 0 set for first run.
+ * After calling execbuf cache is altered with new addresses. As intel-bb
+ * works in reloc mode addresses are only suggestion to the driver and we
+ * cannot be sure they won't change at next exec.
+ *
+ * 2. with allocator
+ *
+ * This mode is valid only for ppgtt. Addresses are acquired from allocator
+ * and softpinned. intel-bb cache must be then coherent with allocator
+ * (simple is coherent, random is not due to fact we don't keep its state).
+ * When we do intel-bb reset with purging cache it has to reacquire addresses
+ * from allocator (allocator should return same address - what is true for
+ * simple allocator and false for random as mentioned before).
+ *
+ * If we do reset without purging caches we use addresses from intel-bb cache
+ * during execbuf objects construction.

We want to use relocations as long as we can so change intel-bb
strategy to use it as default up to gen12. For gen12 we have
to use softpinning in ccs aux tables so there we enforce using
allocator instead of relocations.

Previously intel-bb just used default allocator settings (safe,
chosen for work from the box). But limitation is not good if we want
to exercise non-standard cases (vm ranges for example). As allocator
provides passing full settings lets intel-bb also allows to use them.

From: Zbigniew Kempczyński @ 2021-02-16 11:39 UTC (permalink / raw)
To: igt-dev
From now on intel_bb starts tracking added/removed intel_bufs.
We're safe now regardless order of intel_buf close/destroy
or intel_bb destroy paths.
When intel_buf is closed/destroyed first and it was previously added
to intel_bb it calls the code which removes itself from intel_bb.
In destroy path we go over all tracked intel_bufs and clear tracking
information and buffer offset (it is set to INTEL_BUF_INVALID_ADDRESS).
Reset path is handled as follows:
- intel_bb_reset(ibb, false) - just clean objects array leaving
cache / allocator state intact.
- intel_bb_reset(ibb, true) - purge cache as well as detach intel_bufs
from intel_bb (release offsets from allocator).
Remove intel_bb_object_offset_to_buf() function as tracking intel_buf
updates (checks for allocator) their offsets after execbuf.
Alter api_intel_bb according to intel-bb changes.

To: igt-dev
We need to have same size when intel_buf is initialized over fb
(with compression) because allocator could be called with smaller
size what could lead to relocation.
Use new intel_buf function which allows initalize with handle and size.

From: Zbigniew Kempczyński @ 2021-02-16 11:39 UTC (permalink / raw)
To: igt-dev
intel_bb was adopted to use allocator. Change the test to verify
addresses in different scenarios - with relocations and with softpin.
v2: skip addresses which are beyond allocator range in check-canonical
v3: adding intel-buf to intel-bb inserts addresses so they should
be same even if intel-bb cache purge was called

As intel-bb uses internally decanonical address for objects/intel_bufs
checking canonical bits makes no sense anymore.

A simple test which uses allocator and can be easily copy-paste
when intel-bb is used for batchbuffer creation.

We want to use address returned from emit_reloc() but do not call
kernel relocation path. Change intel-bb to use allocator to fully
control addresses passed in execbuf.

Allocator code is fragile as it runs in multiprocess environment so
we want to validate its memory consistency using address sanitizer.
As allocator thread is spawned in the main process we need to
create children first before it will start allocating. Otherwise
we can incidentally pass shadow map snapshot to child/children
giving false-positive in sanitizer and fail the test.
Playing with sanitizer reveals it has a bug when multiple children
exists and signals are delivered to them. So we must be careful
when sanitizer and igt_fork_signal_handler() are used together.
Bug is revealed with code:

Simplified version of non-fork test which can be used as a copy-paste
template. Uses blit to show how to prepare batch with addresses
acquired from allocator.

Exercise objects offsets produced by the allocator for execbuf
are valid and no EINVAL/ENOSPC occurs. Check it works properly
also for multiprocess allocations/execbufs for same context.
As we're in full-ppgtt we disable softpin to verify offsets produced
by the allocator are valid and kernel doesn't want to relocate them.
Add allocator-basic and allocator-basic-reserve to BAT.

To: igt-dev
As intel_bb "opens" connection to allocator when test completes it can
leave allocator in unknown state (mostly in failed tests). As igt_core
was armed in resetting allocator infrastructure connection to it inside
intel_bb is not valid anymore. Trying to use it leads to catastrofic
errors.
Migrate intel_bb out of fixture and create it inside tests individually.

Generally when playing with intel_buf we should use wrapper code
instead of adding it to intel_bb directly. Code checks required
alignment on specific gens so protects us from passing unaligned
properly addresses.

Tests work in multiprocess environment so we must turn on/off
thread in parent process which is responsible for allocations.

As intel_bb has some strong requirements when allocator is in use
(addresses cannot move when simple allocator is used) ensure gem
buffer which is created from flink will reacquire new address.

Currently we need to ensure intel_buf is a part of single ibb due
to fact it is acquiring address from allocator so we cannot keep
it in two separate ibbs (theoretically it is possible when different
ibbs would be in same context but it is not currently implemented).

Use intel allocator directly, without intel-bb infrastructure.
v2: for relocations suggests use incremented offsets instead of 0.
