TTM doesn't support fair eviction via WW locking, this mitigated in by
using retry loops in exec and preempt rebind worker. Extend this retry
loop to BO allocation. Once TTM supports fair eviction this patch can be
reverted.

Add migrate_device_pfns which prepares an array of pre-populated device
pages for migration. This is needed for eviction of known set of
non-contiguous devices pages to cpu pages which is a common case for SVM
in DRM drivers using TTM.

- Drop extra mmu invalidation (Vetter)
v3:
- s/migrate_device_prepopulated_range/migrate_device_pfns (Alistar)
- Use helper to lock device pages (Alistar)
- Update commit message with why this is required (Alistar)

Avoid multiple CPU page faults to the same device page racing by trying
to lock the page in do_swap_page before taking an extra reference to the
page. This prevents scenarios where multiple CPU page faults each take
an extra reference to a device page, which could abort migration in
folio_migrate_mapping. With the device page being locked in
do_swap_page, the migrate_vma_* functions need to be updated to avoid
locking the fault_page argument.
Prior to this change, a livelock scenario could occur in Xe's (Intel GPU
DRM driver) SVM implementation if enough threads faulted the same device
page.
v3:
- Put page after unlocking page (Alistair)
- Warn on spliting a TPH which is fault page (Alistair)
- Warn on dst page == fault page (Alistair)
v6:
- Add more verbose comment around THP (Alistair)

Introduce drm_pagemap ops to map and unmap dma to VRAM resources. In the
local memory case it's a matter of merely providing an offset into the
device's physical address. For future p2p the map and unmap functions may
encode as needed.
Similar to how dma-buf works, let the memory provider (drm_pagemap) provide
the mapping functionality.
v3:
- Move to drm level include
v4:
- Fix kernel doc (G.G.)

Introduce xe_bo_put_async to put a bo where the context is such that
the bo destructor can't run due to lockdep problems or atomic context.
If the put is the final put, freeing will be done from a work item.

This patch introduces support for GPU Shared Virtual Memory (SVM) in the
Direct Rendering Manager (DRM) subsystem. SVM allows for seamless
sharing of memory between the CPU and GPU, enhancing performance and
flexibility in GPU computing tasks.
The patch adds the necessary infrastructure for SVM, including data
structures and functions for managing SVM ranges and notifiers. It also
provides mechanisms for allocating, deallocating, and migrating memory
regions between system RAM and GPU VRAM.
This is largely inspired by GPUVM.
v2:
- Take order into account in check pages
- Clear range->pages in get pages error
- Drop setting dirty or accessed bit in get pages (Vetter)
- Remove mmap assert for cpu faults
- Drop mmap write lock abuse (Vetter, Christian)
- Decouple zdd from range (Vetter, Oak)
- Add drm_gpusvm_range_evict, make it work with coherent pages
- Export drm_gpusvm_evict_to_sram, only use in BO evict path (Vetter)
- mmget/put in drm_gpusvm_evict_to_sram
- Drop range->vram_alloation variable
- Don't return in drm_gpusvm_evict_to_sram until all pages detached
- Don't warn on mixing sram and device pages
- Update kernel doc
- Add coherent page support to get pages
- Use DMA_FROM_DEVICE rather than DMA_BIDIRECTIONAL
- Add struct drm_gpusvm_vram and ops (Thomas)
- Update the range's seqno if the range is valid (Thomas)
- Remove the is_unmapped check before hmm_range_fault (Thomas)
- Use drm_pagemap (Thomas)
- Drop kfree_mapping (Thomas)
- dma mapp pages under notifier lock (Thomas)
- Remove ctx.prefault
- Remove ctx.mmap_locked
- Add ctx.check_pages
- s/vram/devmem (Thomas)
v3:
- Fix memory leak drm_gpusvm_range_get_pages
- Only migrate pages with same zdd on CPU fault
- Loop over al VMAs in drm_gpusvm_range_evict
- Make GPUSVM a drm level module
- GPL or MIT license
- Update main kernel doc (Thomas)
- Prefer foo() vs foo for functions in kernel doc (Thomas)
- Prefer functions over macros (Thomas)
- Use unsigned long vs u64 for addresses (Thomas)
- Use standard interval_tree (Thomas)
- s/drm_gpusvm_migration_put_page/drm_gpusvm_migration_unlock_put_page (Thomas)
- Drop err_out label in drm_gpusvm_range_find_or_insert (Thomas)
- Fix kernel doc in drm_gpusvm_range_free_pages (Thomas)
- Newlines between functions defs in header file (Thomas)
- Drop shall language in driver vfunc kernel doc (Thomas)
- Move some static inlines from head to C file (Thomas)
- Don't allocate pages under page lock in drm_gpusvm_migrate_populate_ram_pfn (Thomas)
- Change check_pages to a threshold
v4:
- Fix NULL ptr deref in drm_gpusvm_migrate_populate_ram_pfn (Thomas, Himal)
- Fix check pages threshold
- Check for range being unmapped under notifier lock in get pages (Testing)
- Fix characters per line
- Drop WRITE_ONCE for zdd->devmem_allocation assignment (Thomas)
- Use completion for devmem_allocation->detached (Thomas)
- Make GPU SVM depend on ZONE_DEVICE (CI)
- Use hmm_range_fault for eviction (Thomas)
- Drop zdd worker (Thomas)
v5:
- Select Kconfig deps (CI)
- Set device to NULL in __drm_gpusvm_migrate_to_ram (Matt Auld, G.G.)
- Drop Thomas's SoB (Thomas)
- Add drm_gpusvm_range_start/end/size helpers (Thomas)
- Add drm_gpusvm_notifier_start/end/size helpers (Thomas)
- Absorb drm_pagemap name changes (Thomas)
- Fix driver lockdep assert (Thomas)
- Move driver lockdep assert to static function (Thomas)
- Assert mmap lock held in drm_gpusvm_migrate_to_devmem (Thomas)
- Do not retry forever on eviction (Thomas)
v6:
- Fix drm_gpusvm_get_devmem_page alignment (Checkpatch)
- Modify Kconfig (CI)
- Compile out lockdep asserts (CI)

+ * DOC: Overview
+ *
+ * GPU Shared Virtual Memory (GPU SVM) layer for the Direct Rendering Manager (DRM)
+ *
+ * The GPU SVM layer is a component of the DRM framework designed to manage shared
+ * virtual memory between the CPU and GPU. It enables efficient data exchange and
+ * processing for GPU-accelerated applications by allowing memory sharing and
+ * synchronization between the CPU's and GPU's virtual address spaces.
+ *
+ * Key GPU SVM Components:
+ * - Notifiers: Notifiers: Used for tracking memory intervals and notifying the
+ * GPU of changes, notifiers are sized based on a GPU SVM
+ * initialization parameter, with a recommendation of 512M or
+ * larger. They maintain a Red-BlacK tree and a list of ranges that
+ * fall within the notifier interval. Notifiers are tracked within
+ * a GPU SVM Red-BlacK tree and list and are dynamically inserted
+ * or removed as ranges within the interval are created or
+ * destroyed.
+ * - Ranges: Represent memory ranges mapped in a DRM device and managed
+ * by GPU SVM. They are sized based on an array of chunk sizes, which
+ * is a GPU SVM initialization parameter, and the CPU address space.
+ * Upon GPU fault, the largest aligned chunk that fits within the
+ * faulting CPU address space is chosen for the range size. Ranges are
+ * expected to be dynamically allocated on GPU fault and removed on an
+ * MMU notifier UNMAP event. As mentioned above, ranges are tracked in
+ * a notifier's Red-Black tree.
+ * - Operations: Define the interface for driver-specific GPU SVM operations
+ * such as range allocation, notifier allocation, and
+ * invalidations.
+ * - Device Memory Allocations: Embedded structure containing enough information
+ * for GPU SVM 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.
+ *
+ * This layer provides interfaces for allocating, mapping, migrating, and
+ * releasing memory ranges between the CPU and GPU. It handles all core memory
+ * management interactions (DMA mapping, HMM, and migration) and provides
+ * driver-specific virtual functions (vfuncs). This infrastructure is sufficient
+ * to build the expected driver components for an SVM implementation as detailed
+ * below.
+ *
+ * Expected Driver Components:
+ * - GPU page fault handler: Used to create ranges and notifiers based on the
+ * fault address, optionally migrate the range to
+ * device memory, and create GPU bindings.
+ * - Garbage collector: Used to unmap and destroy GPU bindings for ranges.
+ * Ranges are expected to be added to the garbage collector
+ * upon a MMU_NOTIFY_UNMAP event in notifier callback.
+ * - Notifier callback: Used to invalidate and DMA unmap GPU bindings for
+ * ranges.
+ */
+
+/**
+ * DOC: Locking
+ *
+ * GPU SVM handles locking for core MM interactions, i.e., it locks/unlocks the
+ * mmap lock as needed.
+ *
+ * GPU SVM introduces a global notifier lock, which safeguards the notifier's
+ * range RB tree and list, as well as the range's DMA mappings and sequence
+ * number. GPU SVM manages all necessary locking and unlocking operations,
+ * except for the recheck range's pages being valid
+ * (drm_gpusvm_range_pages_valid) when the driver is committing GPU bindings. This
+ * lock corresponds to the 'driver->update' lock mentioned in the HMM
+ * documentation (TODO: Link). Future revisions may transition from a GPU SVM
+ * global lock to a per-notifier lock if finer-grained locking is deemed
+ * necessary.
+ *
+ * In addition to the locking mentioned above, the driver should implement a
+ * lock to safeguard core GPU SVM function calls that modify state, such as
+ * drm_gpusvm_range_find_or_insert and drm_gpusvm_range_remove. This lock is
+ * denoted as 'driver_svm_lock' in code examples. Finer grained driver side
+ * locking should also be possible for concurrent GPU fault processing within a
+ * single GPU SVM. The 'driver_svm_lock' can be via drm_gpusvm_driver_set_lock
+ * to add annotations to GPU SVM.
+ */
+
+/**
+ * DOC: Migration
+ *
+ * The migration support is quite simple, allowing migration between RAM and
+ * device memory at the range granularity. For example, GPU SVM currently does not
+ * support mixing RAM and device memory pages within a range. This means that upon GPU
+ * fault, the entire range can be migrated to device memory, and upon CPU fault, the
+ * entire range is migrated to RAM. Mixed RAM and device memory storage within a range
+ * could be added in the future if required.
+ *
+ * The reasoning for only supporting range granularity is as follows: it
+ * simplifies the implementation, and range sizes are driver-defined and should
+ * be relatively small.
+ */
+
+/**
+ * DOC: Partial Unmapping of Ranges
+ *
+ * Partial unmapping of ranges (e.g., 1M out of 2M is unmapped by CPU resulting
+ * in MMU_NOTIFY_UNMAP event) presents several challenges, with the main one
+ * being that a subset of the range still has CPU and GPU mappings. If the
+ * backing store for the range is in device memory, a subset of the backing store has
+ * references. One option would be to split the range and device memory backing store,
+ * but the implementation for this would be quite complicated. Given that
+ * partial unmappings are rare and driver-defined range sizes are relatively
+ * small, GPU SVM does not support splitting of ranges.
+ *
+ * With no support for range splitting, upon partial unmapping of a range, the
+ * driver is expected to invalidate and destroy the entire range. If the range
+ * has device memory as its backing, the driver is also expected to migrate any
+ * remaining pages back to RAM.
+ */

Add the DRM_XE_VM_BIND_FLAG_CPU_ADDR_MIRROR flag, which is used to
create unpopulated virtual memory areas (VMAs) without memory backing or
GPU page tables. These VMAs are referred to as CPU address mirror VMAs.
The idea is that upon a page fault or prefetch, the memory backing and
GPU page tables will be populated.
CPU address mirror VMAs only update GPUVM state; they do not have an
internal page table (PT) state, nor do they have GPU mappings.
It is expected that CPU address mirror VMAs will be mixed with buffer
object (BO) VMAs within a single VM. In other words, system allocations
and runtime allocations can be mixed within a single user-mode driver
(UMD) program.
Expected usage:
- Bind the entire virtual address (VA) space upon program load using the
DRM_XE_VM_BIND_FLAG_CPU_ADDR_MIRROR flag.
- If a buffer object (BO) requires GPU mapping (runtime allocation),
allocate a CPU address using mmap(PROT_NONE), bind the BO to the
mmapped address using existing bind IOCTLs. If a CPU map of the BO is
needed, mmap it again to the same CPU address using mmap(MAP_FIXED)
- If a BO no longer requires GPU mapping, munmap it from the CPU address
space and them bind the mapping address with the
DRM_XE_VM_BIND_FLAG_CPU_ADDR_MIRROR flag.
- Any malloc'd or mmapped CPU address accessed by the GPU will be
faulted in via the SVM implementation (system allocation).
- Upon freeing any mmapped or malloc'd data, the SVM implementation will
remove GPU mappings.
Only supporting 1 to 1 mapping between user address space and GPU
address space at the moment as that is the expected use case. uAPI
defines interface for non 1 to 1 but enforces 1 to 1, this restriction
can be lifted if use cases arrise for non 1 to 1 mappings.
This patch essentially short-circuits the code in the existing VM bind
paths to avoid populating page tables when the
DRM_XE_VM_BIND_FLAG_CPU_ADDR_MIRROR flag is set.
v3:
- Call vm_bind_ioctl_ops_fini on -ENODATA
- Don't allow DRM_XE_VM_BIND_FLAG_CPU_ADDR_MIRROR on non-faulting VMs
- s/DRM_XE_VM_BIND_FLAG_SYSTEM_ALLOCATOR/DRM_XE_VM_BIND_FLAG_CPU_ADDR_MIRROR (Thomas)
- Rework commit message for expected usage (Thomas)
- Describe state of code after patch in commit message (Thomas)
v4:
- Fix alignment (Checkpatch)

acting as a placeholder for follow on patches.
v2:
- Add close function
v3:
- Better commit message (Thomas)
- Kernel doc (Thomas)
- Update chunk array to be unsigned long (Thomas)
- Use new drm_gpusvm.h header location (Thomas)
- Newlines between functions in xe_svm.h (Thomas)
- Call drm_gpusvm_driver_set_lock in init (Thomas)
v6:
- Only compile if CONFIG_DRM_GPUSVM selected (CI, Lucas)

Add dma_addr res cursor which walks an array of drm_pagemap_dma_addr.
Useful for SVM ranges and programing page tables.
v3:
- Better commit message (Thomas)
- Use new drm_pagemap.h location

Clear root PT entry and invalidate entire VM's address space when
closing the VM. Will prevent the GPU from accessing any of the VM's
memory after closing.
v2:
- s/vma/vm in kernel doc (CI)
- Don't nuke migration VM as this occur at driver unload (CI)
v3:
- Rebase and pull into SVM series (Thomas)
- Wait for pending binds (Thomas)
v5:
- Remove xe_gt_tlb_invalidation_fence_fini in error case (Matt Auld)
- Drop local migration bool (Thomas)

I took a look and I think the root cause is that the error injection
IGTs are unbinding the device (like hotunplug) with the vm still being
left open (closed when driver instance is closed) so here the top level
vram mapping has already been unmapped from the kernel address space
during the unbind, and this here is then trying to write through that
mapping. I think we need to sprinkle some drm_dev_enter() here, and
maybe also for the inval below. If the device is already gone then we
should be able to skip it.

Thanks for looking here, this would've confused me for me bit. Will add
drm_dev_enter/exit.

Add SVM range invalidation vfunc which invalidates PTEs. A new PT layer
function which accepts a SVM range is added to support this. In
addition, add the basic page fault handler which allocates a SVM range
which is used by SVM range invalidation vfunc.
v2:
- Don't run invalidation if VM is closed
- Cycle notifier lock in xe_svm_close
- Drop xe_gt_tlb_invalidation_fence_fini
v3:
- Better commit message (Thomas)
- Add lockdep asserts (Thomas)
- Add kernel doc (Thomas)
- s/change/changed (Thomas)
- Use new GPU SVM range / notifier structures
- Ensure PTEs are zapped / dma mappings are unmapped on VM close (Thomas)
v4:
- Fix macro (Checkpatch)
v5:
- Use range start/end helpers (Thomas)
- Use notifier start/end helpers (Thomas)
v6:
- Use min/max helpers (Himal)
- Only compile if CONFIG_DRM_GPUSVM selected (CI, Lucas)

Add DRM_GPUVA_OP_DRIVER which allows driver to define their own gpuvm
ops. Useful for driver created ops which can be passed into the bind
software pipeline.

Add (re)bind to SVM page fault handler. To facilitate add support
function to VM layer which (re)binds a SVM range. Also teach PT layer to
understand (re)binds of SVM ranges.
v2:
- Don't assert BO lock held for range binds
- Use xe_svm_notifier_lock/unlock helper in xe_svm_close
- Use drm_pagemap dma cursor
- Take notifier lock in bind code to check range state
v3:
- Use new GPU SVM range structure (Thomas)
- Kernel doc (Thomas)
- s/DRM_GPUVA_OP_USER/DRM_GPUVA_OP_DRIVER (Thomas)
v5:
- Kernel doc (Thomas)
v6:
- Only compile if CONFIG_DRM_GPUSVM selected (CI, Lucas)

Add basic SVM garbage collector which destroy a SVM range upon a MMU
UNMAP event. The garbage collector runs on worker or in GPU fault
handler and is required as locks in the path of reclaim are required and
cannot be taken the notifier.
v2:
- Flush garbage collector in xe_svm_close
v3:
- Better commit message (Thomas)
- Kernel doc (Thomas)
- Use list_first_entry_or_null for garbage collector loop (Thomas)
- Don't add to garbage collector if VM is closed (Thomas)
v4:
- Use %pe to print error (Thomas)
v5:
- s/visable/visible (Thomas)

uAPI is designed with the use case that only mapping a BO to a malloc'd
address will unbind a CPU-address mirror VMA. Therefore, allowing a
CPU-address mirror VMA to unbind when the GPU has bindings in the range
being unbound does not make much sense. This behavior is not supported,
as it simplifies the code. This decision can always be revisited if a
use case arises.

- Kernel doc (Thomas)
- Newline between function defs (Thomas)
v5:

Add the DRM_XE_QUERY_CONFIG_FLAG_HAS_CPU_ADDR_MIRROR device query flag,
which indicates whether the device supports CPU address mirroring. The
intent is for UMDs to use this query to determine if a VM can be set up
with CPU address mirroring. This flag is implemented by checking if the
device supports GPU faults.

Add functions which migrate to / from VRAM accepting a single DPA
argument (VRAM) and array of dma addresses (SRAM). Used for SVM
migrations.

Add SVM device memory mirroring which enables device pages for
migration. Enabled via CONFIG_XE_DEVMEM_MIRROR Kconfig. Kconfig option
defaults to enabled. If not enabled, SVM will work sans migration and
KMD memory footprint will be less.
v3:
- Add CONFIG_XE_DEVMEM_MIRROR
v4:
- Fix Kconfig (Himal)
- Use %pe to print errors (Thomas)
- Fix alignment issue (Checkpatch)
v5:
- s/xe_mem_region/xe_vram_region (Rebase)
v6:
- Only compile if CONFIG_DRM_GPUSVM selected (CI, Lucas)

Add support for mapping device pages to Xe SVM by attaching drm_pagemap
to a memory region, which is then linked to a GPU SVM devmem allocation.
This enables GPU SVM to derive the device page address.

Migration is implemented with range granularity, with VRAM backing being
a VM private TTM BO (i.e., shares dma-resv with VM). The lifetime of the
TTM BO is limited to when the SVM range is in VRAM (i.e., when a VRAM
SVM range is migrated to SRAM, the TTM BO is destroyed).
The design choice for using TTM BO for VRAM backing store, as opposed to
direct buddy allocation, is as follows:
- DRM buddy allocations are not at page granularity, offering no
advantage over a BO.
- Unified eviction is required (SVM VRAM and TTM BOs need to be able to
evict each other).
- For exhaustive eviction [1], SVM VRAM allocations will almost certainly
require a dma-resv.
- Likely allocation size is 2M which makes of size of BO (872)
acceptable per allocation (872 / 2M == .0004158).
With this, using TTM BO for VRAM backing store seems to be an obvious
choice as it allows leveraging of the TTM eviction code.
Current migration policy is migrate any SVM range greater than or equal
to 64k once.
[1] https://patchwork.freedesktop.org/series/133643/
v2:
- Rebase on latest GPU SVM
- Retry page fault on get pages returning mixed allocation
- Use drm_gpusvm_devmem
v3:
- Use new BO flags
- New range structure (Thomas)
- Hide migration behind Kconfig
- Kernel doc (Thomas)
- Use check_pages_threshold
v4:
- Don't evict partial unmaps in garbage collector (Thomas)
- Use %pe to print errors (Thomas)
- Use %p to print pointers (Thomas)
v5:
- Use range size helper (Thomas)
- Make BO external (Thomas)
- Set tile to NULL for BO creation (Thomas)
- Drop BO mirror flag (Thomas)
- Hold BO dma-resv lock across migration (Auld, Thomas)
v6:
- s/drm_info/drm_dbg (Thomas)
- s/migrated/skip_migrate (Himal)
- Better debug message on VRAM migration failure (Himal)
- Drop return BO from VRAM allocation function (Thomas)

Wire xe_bo_move to GPU SVM migration via new helper xe_svm_bo_evict.
v2:
- Use xe_svm_bo_evict
- Drop bo->range
v3:
- Kernel doc (Thomas)
v4:
- Add missing xe_bo.c code
v5:
- Add XE_BO_FLAG_CPU_ADDR_MIRROR flag in this patch (Thomas)
- Add message on eviction failure
v6:
- Only compile if CONFIG_DRM_GPUSVM selected (CI, Lucas)

Add some useful SVM debug logging fro SVM range which prints the range's
state.
v2:
- Update logging with latest structure layout
v3:
- Better commit message (Thomas)
- New range structure (Thomas)
- s/COLLECTOT/s/COLLECTOR (Thomas)
v4:
- Drop partial evict message (Thomas)
- Use %p for pointers print (Thomas)
v6:
- Cast dma_addr to u64 (CI)
- Only compile if CONFIG_DRM_GPUSVM selected (CI, Lucas)

a real migration policy is implemented. Can be removed once migration
policy is implemented.

+ * Races (especially against concurrent eviction or migrate_to_ram)

+ * Notifier lock only protects range tree, pages valid state for a range
+ (rather than seqno due to wider notifiers), pagetable entries, and
+ mmu notifier seqno tracking, it is not a global lock to protect

As a general comment I think it would be nice if we could add some rational/
reasons for these design principals. Things inevitably change and if/when
we need to violate or update these principals it would be good to have some
documented rational for why we decided on them in the first place because the
reasoning may have become invalid by then.

In principal I agree. The problem I think you will run into is the analogue of
what adding a trylock_page() to do_swap_page() fixes. Which is that a concurrent
GPU fault (which is higly likely after handling a CPU fault due to the GPU PTEs
becoming invalid) may, depending on your design, kick off a migration of the
page to the GPU via migrate_vma_setup().
The problem with that is migrate_vma_setup() will temprarily raise the folio
refcount, which can cause the migrate_to_ram() callback to fail but the elevated
refcount from migrate_to_ram() can also cause the GPU migration to fail thus
leading to a live-lock when both CPU and GPU fault handlers just keep retrying.
This was particularly problematic for us on multi-GPU setups, and our solution
was to introduce a migration critical section in the form of a mutex to ensure
only one thread was calling migrate_vma_setup() at a time.
And now that I've looked at UVM development history, and remembered more
context, this is why I had a vague recollection that adding a migration entry
in do_swap_page() would be better than taking a page lock. Doing so fixes the
issue with concurrent GPU faults blocking migrate_to_ram() because it makes
migrate_vma_setup() ignore the page.

This is a term that seems be somewhat overloaded depending on context so a
definition would be nice. Is your view of eviction migrating data from GPU back
to CPU without a virtual address to free up GPU memory? (that's what I think of,

Again, one of the issues here (particularly with multi-GPU setups) is that it's
very easy to live-lock with rety loops because even attempting a migration that
fails can cause migration/fault handling in other threads to fail, either by
calling mmu_notifiers or taking a page reference.
Those are probably things that we should fix on the MM side, but for now UVM at
least uses a lock to ensure forward progress.

See my earlier comments. Although note I agree with this in principal, and we do
just retry if taking the lock fails.

Agree. And my rational is because core-MM can update the virtual address for a
page without notifying a driver of the new address. For example with mremap().
So it's impossible to keep any backpointer to a virtual address up to date.

Agree. And presumably the rational is because it is very difficult to safely
update page->zone_device_data and ensure there aren't concurrent users of it
unless the page is free (ie. has a 0 refcount)?

I'm hoping my patch series[1] to allow for compound device pages will land in v6.15
as well. The next steps are extending that to DEVICE_PRIVATE pages with
migrate_vma_setup() and migrate_to_ram() and we have been making some good
progress on this internally. I hope to have something posted before LSFMM.
The other thing we have been looking at here is being able to migrate
file-backed pages to GPU memory.

Ok, this is something to keep an eye on. In the current Xe code, we try
to migrate a chunk of memory from the CPU to the GPU in our GPU fault
handler once per fault. If it fails due to racing CPU access, we simply
leave it in CPU memory and move on. We don't have any real migration
policies in Xe yet—that is being worked on as a follow-up to my series.
However, if we had a policy requiring a memory region to 'must be in
GPU,' this could conceivably lead to a livelock with concurrent CPU and
GPU access. I'm still not fully convinced that a driver-side lock is the
solution here, but without encountering the issue on our side, I can't
be completely certain what the solution is.

Again, see above. Right now, migration in Xe is more of a best-case
scenario rather than a mandatory process, and perhaps this is masking an
issue.
Maybe I should add a comment here stating your possible concerns and that
Xe will be implementing real migration policies and multi-GPU support
soon. If this issue arises, we can revisit the locking guidelines or
perhaps help contribute to the necessary core changes to make this work
properly.

I don't see any barriers either, I think it would work in Xe with slight

Right - we have migration policies that can cause us to try harder to migrate.
Also I agree with you that a driver-side lock might not be the best solution
here. It's what we did due to various limiations we have, but they are
unimportant for this discussion.
I agree the ideal solution wouldn't involve locks and would instead be to fix
the migration interfaces up such that one thread attempting to migrate doesn't
cause another thread which has started a migration to fail. The solution to that
isn't obvious, but I don't think it would be impossible either.

Sounds good. So eviction is just migration of physical memory.

Except of course whatever virtual memory data structures the core-MM needs to
touch in order to do the migration right? Agree that the driver shouldn't be
touching any driver data structures that concern themselves with virtual memory
addresses though. Except what about any data structures that are required as
part of GPU PTE/TLB invalidation?

Yeah, that could be good. Something along the lines of core-MM code may need
fixing in the way I described above (one thread attempting a migration shouldn't
cause another thread that's already started one to fail).

There's probably not much of direct interest to you there at the moment. It's a
prerequisite in that it allows current (and therefore future) users of compound
ZONE_DEVICE pages to have them ref-counted normally, instead of the funky scheme
DAX uses at the moment. Our changes will build on top of that.

The eviction is triggered via the new function I added in this series
migrate_device_pfns, this triggers the notifier which invalidates the
virtual GPU address page tables. So the eviction code itself is only
looking at the physical memory. I can add something here to make this a
bit clear.
