drm/i915: Walk crtcs in pipe order
Currently our crtcs are registered in pipe order, and thus all the for_intel_crtc*() iterators walk the crtcs in pipe order. There are a bunch of places that more or less depend on that. Eg. during plane updates and such we want joined pipes to be processed back-to-back to give a better chance of an atomic update across the whole set. When we start to register crtcs in a different order we don't want to change the order in which the pipes get handled. Decouple the for_each_intel_crtc*() iterators from the crtc registration order by using a separate list which will be sorted by the pipe rather than the crtc index. We could probably use a simple array or something, but that would require some kind of extra iterator variable for the macros, and thus would require a lot more changes. Using a linked list keeps the fallout minimal. We can look at using a more optimal data structure later. I also added this extra junk to the atomic state iterators: "(__i) = drm_crtc_index(&(crtc)->base), (void)(__i)" even though the macro itself no longer needs the "__i" iterator. This in case the "__i" is used by the caller, and to avoid compiler warnings if it's completely unused now. v2: Flip the pipe comparison (Jani) Reviewed-by: Jani Nikula <jani.nikula@intel.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patch.msgid.link/20260408155744.13326-3-ville.syrjala@linux.intel.com Signed-off-by: Jani Nikula <jani.nikula@intel.com> |

drm/xe: Avoid memory allocations in xe_device_declare_wedged()
xe_device_declare_wedged() runs in the DMA-fence signaling path, where GFP_KERNEL memory allocations are not allowed. However, registering xe_device_wedged_fini via drmm_add_action_or_reset() triggers a GFP_KERNEL allocation. Fix this by deferring the registration of xe_device_wedged_fini until late in the driver load sequence. Additionally, drop the wedged PM reference only if the device is actually wedged in xe_device_wedged_fini. Fixes: |

The default case of the PXP suspend switch is incorrectly exiting without releasing the lock.

Therefore, we can just get rid of the default case and rely on the compiler to warn us if a new enum value is added and we forget to add it to the switch. Fixes: |

drm/xe/madvise: Enable purgeable buffer object IOCTL support
Hook the madvise_purgeable() handler into the madvise IOCTL now that all supporting infrastructure is complete: - Core purge implementation (patch 3) - BO state tracking and helpers (patches 1-2) - Per-VMA purgeable state tracking (patch 6) - Shrinker integration for memory reclamation (patch 10) This final patch enables userspace to use the DRM_XE_VMA_ATTR_PURGEABLE_STATE madvise type to mark buffers as WILLNEED/DONTNEED and receive the retained status indicating whether buffers were purged. The feature was kept disabled in earlier patches to maintain bisectability and ensure all components are in place before exposing to userspace. Userspace can detect kernel support for purgeable BOs by checking the DRM_XE_QUERY_CONFIG_FLAG_HAS_PURGING_SUPPORT flag in the query_config response.

The mmap offset ioctl now checks the BO's purgeable state before allowing userspace to establish a new CPU mapping. This prevents the race where userspace gets a valid offset but the BO is purged before actual faulting begins. Existing mmaps (established before DONTNEED) may still work until pages are purged, at which point CPU faults fail with SIGBUS.

drm/xe/madvise: Block imported and exported dma-bufs
Prevent marking imported or exported dma-bufs as purgeable. External devices may be accessing these buffers without our knowledge, making purging unsafe.

drm/xe/madvise: Implement per-VMA purgeable state tracking
Track purgeable state per-VMA instead of using a coarse shared BO check. This prevents purging shared BOs until all VMAs across all VMs are marked DONTNEED. Add xe_bo_all_vmas_dontneed() to check all VMAs before marking a BO purgeable. Add xe_bo_recheck_purgeable_on_vma_unbind() to handle state transitions when VMAs are destroyed - if all remaining VMAs are DONTNEED the BO can become purgeable, or if no VMAs remain it transitions to WILLNEED. The per-VMA purgeable_state field stores the madvise hint for each mapping. Shared BOs can only be purged when all VMAs unanimously indicate DONTNEED. This prevents the bug where unmapping the last VMA would incorrectly flip a DONTNEED BO back to WILLNEED. The enum-based state check preserves BO state when no VMAs remain, only updating when VMAs provide explicit hints.

drm/xe/vm: Prevent binding of purged buffer objects
Add purge checking to vma_lock_and_validate() to block new mapping operations on purged BOs while allowing cleanup operations to proceed. Purged BOs have their backing pages freed by the kernel. New mapping operations (MAP, PREFETCH, REMAP) must be rejected with -EINVAL to prevent GPU access to invalid memory. Cleanup operations (UNMAP) must be allowed so applications can release resources after detecting purge via the retained field. REMAP operations require mixed handling - reject new prev/next VMAs if the BO is purged, but allow the unmap portion to proceed for cleanup. The check_purged flag in struct xe_vma_lock_and_validate_flags distinguishes between these cases: true for new mappings (must reject), false for cleanup (allow).

drm/xe/bo: Block CPU faults to purgeable buffer objects
Block CPU page faults to buffer objects marked as purgeable (DONTNEED) or already purged. Once a BO is marked DONTNEED, its contents can be discarded by the kernel at any time, making access undefined behavior. Return VM_FAULT_SIGBUS immediately to fail consistently instead of allowing erratic behavior where access sometimes works (if not yet purged) and sometimes fails (if purged). For DONTNEED BOs: - Block new CPU faults with SIGBUS to prevent undefined behavior. - Existing CPU PTEs may still work until TLB flush, but new faults fail immediately. For PURGED BOs: - Backing store has been reclaimed, making CPU access invalid. - Without this check, accessing existing mmap mappings would trigger xe_bo_fault_migrate() on freed backing store, causing kernel hangs or crashes. The purgeable check is added to both CPU fault paths: - Fastpath (xe_bo_cpu_fault_fastpath): Returns VM_FAULT_SIGBUS immediately under dma-resv lock, preventing attempts to migrate/validate DONTNEED/purged pages. - Slowpath (xe_bo_cpu_fault): Returns -EFAULT under drm_exec lock, converted to VM_FAULT_SIGBUS.

drm/xe/madvise: Implement purgeable buffer object support
This allows userspace applications to provide memory usage hints to
the kernel for better memory management under pressure:
Add the core implementation for purgeable buffer objects, enabling
memory reclamation of user-designated DONTNEED buffers during eviction.
This patch implements the purge operation and state machine transitions:
Purgeable States (from xe_madv_purgeable_state):
- WILLNEED (0): BO should be retained, actively used
- DONTNEED (1): BO eligible for purging, not currently needed
- PURGED (2): BO backing store reclaimed, permanently invalid
Design Rationale:
- Async TLB invalidation via trigger_rebind (no blocking
xe_vm_invalidate_vma)
- i915 compatibility: retained field, "once purged always purged"
semantics
- Shared BO protection prevents multi-process memory corruption
- Scratch PTE reuse avoids new infrastructure, safe for fault mode
Note: The madvise_purgeable() function is implemented but not hooked
into the IOCTL handler (madvise_funcs[] entry is NULL) to maintain
bisectability. The feature will be enabled in the final patch when all
supporting infrastructure (shrinker, per-VMA tracking) is complete.

drm/xe/bo: Add purgeable bo state tracking and field madv to xe_bo
Add infrastructure for tracking purgeable state of buffer objects.
This includes:
Introduce enum xe_madv_purgeable_state with three states:
- XE_MADV_PURGEABLE_WILLNEED (0): BO is needed and should not be
purged. This is the default state for all BOs.
- XE_MADV_PURGEABLE_DONTNEED (1): BO is not currently needed and
can be purged by the kernel under memory pressure to reclaim
resources. Only non-shared BOs can be marked as DONTNEED.
- XE_MADV_PURGEABLE_PURGED (2): BO has been purged by the kernel.
Accessing a purged BO results in error. Follows i915 semantics
where once purged, the BO remains permanently invalid ("once
purged, always purged").
Add madv_purgeable field to struct xe_bo for state tracking
of purgeable state across concurrent access paths

drm/xe: Issue GGTT invalidation under lock in ggtt_node_remove
Async work (e.g., GuC queue teardowns) can call ggtt_node_remove, so the
operation must be performed under the GGTT lock to ensure the GGTT
online check remains stable. GGTT insertion and removal are heavyweight
operations (e.g., queue create/destroy), so the additional serialization
cost is negligible compared to ensuring correctness.

It shouldn't be invalid since this is a re-insertion, so must have worked before. Leaving the likely culprit as something already placed where we want to insert the vma. Following from that, for the case where we do something like a rebind in the middle of a vma, and one or both mapped ends are already compatible, we skip doing the rebind of those vma and set next/prev to NULL. As well as then adjust the original unmap va range, to avoid unmapping the ends. However, if we trigger the unwind path, we end up with three va, with the two ends never being removed and the original va range in the middle still being the shrunken size. If this occurs, one failure mode is when another unwind op needs to interact with that range, which can happen with a vector of binds. For example, if we need to re-insert something in place of the original va. In this case the va is still the shrunken version, so when removing it and then doing a re-insert it can overlap with the ends, which were never removed, triggering a warning like above, plus leaving the vm in a bad state. With that, we need two things here: 1) Stop nuking the prev/next tracking for the skip cases. Instead relying on checking for skip prev/next, where needed. That way on the unwind path, we now correctly remove both ends. 2) Undo the unmap va shrinkage, on the unwind path. With the two ends now removed the unmap va should expand back to the original size again, before re-insertion. v2: - Update the explanation in the commit message, based on an actual IGT of triggering this issue, rather than conjecture. - Also undo the unmap shrinkage, for the skip case. With the two ends now removed, the original unmap va range should expand back to the original range. v3: - Track the old start/range separately. vma_size/start() uses the va info directly.

Which seems to hint that the vma we are re-inserting for the ops unwind
is either invalid or overlapping with something already inserted in the
vm. It shouldn't be invalid since this is a re-insertion, so must have
worked before. Leaving the likely culprit as something already placed
where we want to insert the vma.
Following from that, for the case where we do something like a rebind in
the middle of a vma, and one or both mapped ends are already compatible,
we skip doing the rebind of those vma and set next/prev to NULL. As well
as then adjust the original unmap va range, to avoid unmapping the ends.
However, if we trigger the unwind path, we end up with three va, with
the two ends never being removed and the original va range in the middle
still being the shrunken size.
If this occurs, one failure mode is when another unwind op needs to
interact with that range, which can happen with a vector of binds. For
example, if we need to re-insert something in place of the original va.
In this case the va is still the shrunken version, so when removing it
and then doing a re-insert it can overlap with the ends, which were
never removed, triggering a warning like above, plus leaving the vm in a
bad state.
With that, we need two things here:
1) Stop nuking the prev/next tracking for the skip cases. Instead
relying on checking for skip prev/next, where needed. That way on the
unwind path, we now correctly remove both ends.
2) Undo the unmap va shrinkage, on the unwind path. With the two ends
now removed the unmap va should expand back to the original size again,
before re-insertion.
v2:
- Update the explanation in the commit message, based on an actual IGT of
triggering this issue, rather than conjecture.
- Also undo the unmap shrinkage, for the skip case. With the two ends
now removed, the original unmap va range should expand back to the
original range.
v3:
- Track the old start/range separately. vma_size/start() uses the va
info directly.

drm/i915/de: Implement register polling in the display code
The plan is to move all the mmio stuff into the display code itself.
As a first step implement the register polling in intel_de.c.
Currently i915 and xe implement this stuff in slightly different
ways, so there are some functional changes here. Try to go for a
reasonable middle ground between the i915 and xe implementations:
- the exponential backoff limit is the simpler approach taken
by i915 (== just clamp the max sleep duration to 1 ms)
- the fast vs. slow timeout handling is similar to i915 where
we first try the fast timeout and then again the slow timeout
if the condition still isn't satisfied. xe just adds up the
timeouts together, which is a bit weird.
- the atomic wait variant uses udelay() like xe, whereas i915
has no udelay()s in its atomic loop. As a compromise go for a
fixed 1 usec delay for short waits, instead of the somewhat
peculiar xe behaviour where it effectively just does one
iteration of the loop.
- keep the "use udelay() for < 10 usec waits" logic (which
more or less mirrors fsleep()), but include an explicit
might_sleep() even for these short waits when called from
a non-atomic intel_de_wait*() function. This should prevent
people from calling the non-atomic functions from the wrong
place.
Eventually we may want to switch over to poll_timeout*(),
but that lacks the exponential backoff, so a bit too
radical to change in one go.
v2: Initialize ret in intel_de_wait_for_register() to avoid a
warning from the compiler. This is actually a false positive
since we always have fast_timeout_us!=0 when slow_timeout_us!=0,
but the compiler can't see that

drm/i915/de: Introduce intel_de.c and move intel_de_{read,write}8() there
intel_de_{read,write}8() aren't performance critical so having them
