Don't rely on CONFIG_DRM_GPUSVM because other drivers may enable it
causing us to compile in SVM support unintentionally.
Also take the opportunity to leave more code out of compilation if
!CONFIG_DRM_XE_GPUSVM and !CONFIG_DRM_XE_DEVMEM_MIRROR

If drm_gpusvm_migrate_to_devmem() succeeds, if a cpu access happens to the
range the bo may be freed before xe_bo_unlock(), causing a UAF.
Since the reference is transferred, use xe_svm_devmem_release() to
release the reference on drm_gpusvm_migrate_to_devmem() failure,
and hold a local reference to protect the UAF.

From: Matthew Brost <matthew.brost@intel.com>
The migration functionality and track-keeping of per-pagemap VRAM
mapped to the CPU mm is not per GPU_vm, but rather per pagemap.
This is also reflected by the functions not needing the drm_gpusvm
structures. So move to drm_pagemap.
With this, drm_gpusvm shouldn't really access the page zone-device-data
since its meaning is internal to drm_pagemap. Currently it's used to
reject mapping ranges backed by multiple drm_pagemap allocations.
For now, make the zone-device-data a void pointer.
Rename CONFIG_DRM_XE_DEVMEM_MIRROR to CONFIG_DRM_XE_PAGEMAP.
Matt is listed as author of this commit since he wrote most of the code,
and it makes sense to retain his git authorship.
Thomas mostly moved the code around.

+/**
+ * DOC: Overview
+ *
+ * The DRM pagemap layer is intended to augment the dev_pagemap functionality by
+ * providing a way to populate a struct mm_struct virtual range with device
+ * private pages and to provide helpers to abstract device memory allocations,
+ * to migrate memory back and forth between device memory and system RAM and
+ * to handle access (and in the future migration) between devices implementing
+ * a fast interconnect that is not necessarily visible to the rest of the
+ * system.
+ *
+ * Typically the DRM pagemap receives requests from one or more DRM GPU SVM
+ * instances to populate struct mm_struct virtual ranges with memory, and the
+ * migration is best effort only and may thus fail. The implementation should
+ * also handle device unbinding by blocking (return an -ENODEV) error for new
+ * population requests and after that migrate all device pages to system ram.
+ */
+
+/**
+ * DOC: Migration
+ * Migration granularity typically follows the GPU SVM range requests, but
+ * if there are clashes, due to races or due to the fact that multiple GPU
+ * SVM instances have different views of the ranges used, and because of that
+ * parts of a requested range is already present in the requested device memory,
+ * the implementation has a variety of options. It can fail and it can choose
+ * to populate only the part of the range that isn't already in device memory,
+ * and it can evict the range to system before trying to migrate. Ideally an
+ * implementation would just try to migrate the missing part of the range and
+ * allocate just enough memory to do so.
+ *
+ * When migrating to system memory as a response to a cpu fault or a device
+ * memory eviction request, currently a full device memory allocation is
+ * migrated back to system. Moving forward this might need improvement for
+ * situations where a single page needs bouncing between system memory and
+ * device memory due to, for example, atomic operations.
+ *
+ * Key DRM pagemap components:
+ *
+ * - Device Memory Allocations:
+ * Embedded structure containing enough information for the drm_pagemap to
+ * migrate to / from device memory.
+ *
+ * - Device Memory Operations:
+ * Define the interface for driver-specific device memory operations
+ * release memory, populate pfns, and copy to / from device memory.

Add runtime PM since we might call populate_mm on a foreign device.
Also create the VRAM bos as ttm_bo_type_kernel. This avoids the
initial clearing and the creation of an mmap handle.

This is a step towards adding drm_pagemaps on demand.

On device unbind, migrate exported bos, including pagemap bos to
system. This allows importers to take proper action without
disruption. In particular, SVM clients on remote devices may
continue as if nothing happened, and can chose a different
placement.
The evict_flags() placement is chosen in such a way that bos that
aren't exported are purged.

The hmm_range_fault() and the migration helpers currently need a common
"owner" to identify pagemaps and clients with fast interconnect.
Add a drm_pagemap utility to setup such owners by registering
drm_pagemaps, in a registry, and for each new drm_pagemap,
query which existing drm_pagemaps have fast interconnects with the new
drm_pagemap.
The "owner" scheme is limited in that it is static at drm_pagemap creation.
Ideally one would want the owner to be adjusted at run-time, but that
requires changes to hmm. If the proposed scheme becomes too limited,
we need to revisit.

Register a driver-wide owner list, provide a callback to identify
fast interconnects and use the drm_pagemap_util helper to allocate
or reuse a suitable owner struct. For now we consider pagemaps on
different tiles on the same device as having fast interconnect.

With SVM, ranges forwarded to the PT code for binding can, mostly
due to races when migrating, point to both VRAM and system / foreign
device memory. Make the PT code able to handle that by checking,
for each PTE set up, whether it points to local VRAM or to system
memory.

Racing while migrating can cause part of an SVM range to reside in
system and part of the range to reside in local VRAM.
Currently we disallow that and repeatedly try to force everything
out to system memory.
Instead, allow drm_gpusvm_range_get_pages() to be a bit more permissive,
and allow mapping of mixed ranges.

Introduce a preferred dpagemap, that can override the default.
The default is still the local tile vram dpagemap.
The preferred pagemap is intended to be set from user-space.

Falicitate implementing uapi representing a struct drm_pagemap
as a file descriptor.
A drm_pagemap file descriptor holds, while open, a reference to
the struct drm_pagemap and to the drm_pagemap_helper module.

The drm_pagemap functionality does not depend on the device having
recoverable pagefaults available. So allow xe_migrate_vram() also for
such devices. Even if this will have little use in practice, it's
beneficial for testin multi-device SVM, since a memory provider could
be a non-pagefault capable gpu.

As a POC, add an xe_madvise_prefer_devmem IOCTL so that the user
can set the preferred pagemap to migrate to for a given memory
region (in this POC, the memory region is the whole GPU VM).
This is intended to be replaced by a proper madvise IOCTL, probably
with improved functionality

Up till here that makes sense. Maybe not necessary to be put into the DRM layer, but that is an implementation detail.

But this completely eludes me.
Why would you want an UAPI for representing pagemaps as file descriptors? Isn't it the kernel which enumerates the interconnects of the devices?
I mean we somehow need to expose those interconnects between devices to userspace, e.g. like amdgpu does with it's XGMI connectors. But that is static for the hardware (unless HW is hot removed/added) and so I would assume exposed through sysfs.

Thanks for the feedback.
The idea here is not to expose the interconnects but rather have a way
for user-space to identify a drm_pagemap and some level of access- and
lifetime control.
For Xe, If an application wants to use a particular drm_pagemap it
calls an ioctl:
pagemap_fd = drm_xe_ioctl_pagemap_open(exporting_device_fd,
memory_region);
And then when it's no longer used
close(pagemap_fd)
To use it for a memory range, the intended idea is call gpu madvise
ioctl:
err = drm_xe_ioctl_gpu_madvise(local_device_fd, range, pagemap_fd);
Now, if there is no fast interconnect between the two, the madvise call
could just return an error. All this ofc assumes that user-space is
somehow aware of the fast interconnect topology but how that is exposed
is beyond the scope of this first series. (Suggestions welcome).
The advantage of the above approach is
1) We get some level of access control. If the user doesn't have access
to the exporting device, he/she can't obtain a pagemap file descriptor.
2) Lifetime control. The pagemaps are memory hungry, but also take
considerable time to set up and tear down.
3) It's a driver-independent approach.
One could ofc use a different approach by feeding the gpu_madvise()
ioctl with a remote device file descriptor and whatever information is
needed for the remote device to identify the drm_pagemap. That would
not be driver independent, though. Not sure how important that is.

Well that's what I get I just don't get why?
I mean when you want to have the pagemap as optional feature you can turn on and off I would say make that a sysfs file.
It's a global feature anyway and not bound in any way to the file descriptor, isn't it?

Well should userspace deal with physical addresses here, or what exactly is memory_region here?

As it is currently coded in Xe, the drm_pagemap is revoked when the the
struct files backing the fds are released. (After a delay that is, to
avoid repeatedly destroying and re-creating the pagemap).
Will take the sysfs switch back to the team and discuss what's the
preferred option.

On some hardware we have multiple VRAM banks per device, one per
"tile". The memory_region selects which one to use.

Getting back on this we had some discussions internally on this and the
desired behavior is to have the device-private pages on a firstopen-
lastclose lifetime (Or rather firstopen-(lastclose + shrinker))
lifetime, for memory usage concerns. So I believe a file descriptor is
a good fit for the UAPI representation.
