drm/xe/guc: Exclude indirect ring state page from ADS engine state size
The engine state size reported to GuC via ADS should only include the
engine state portion and should not include the indirect ring state page
that comes after it in the context image. The GuC uses this size to
overwrite the engine state in the LRC on watchdog resets and we don't
want it to overwrite the indirect ring state as well.

drm/xe/pf: Fix MMIO access using PF view instead of VF view during migration
pf_migration_mmio_save() and pf_migration_mmio_restore() initialize a
local VF-specific MMIO view via xe_mmio_init_vf_view() but then pass
>->mmio (the PF base) to all xe_mmio_read32()/xe_mmio_write32()
calls instead of the local &mmio. This causes the PF own SW flag
registers to be saved/restored rather than the target VF registers,
silently corrupting migration state.
Use the VF MMIO view for all register accesses, matching the correct
pattern used in pf_clear_vf_scratch_regs().

drm/xe/pf: Fix EAGAIN sign in pf_migration_consume()
PTR_ERR() returns a negative value, so comparing against the positive
EAGAIN is always true for ERR_PTR(-EAGAIN), causing pf_migration_consume()
to bail out instead of continuing to the remaining GTs. On multi-GT
platforms this can skip GTs that already have data ready.
Compare against -EAGAIN to match the intent (and the following line
that correctly uses -EAGAIN). While at it, gate PTR_ERR() with
IS_ERR().
v2: add IS_ERR() guard before PTR_ERR(). (Gustavo)

drm/xe/hdcp: Add NULL check for media_gt in intel_hdcp_gsc_check_status()
When media GT is disabled via configfs, there is no allocation for
media_gt, which is kept as NULL. In such scenario,
intel_hdcp_gsc_check_status() results in a kernel pagefault error due to
>->uc.gsc being evaluated as an invalid memory address.
Fix that by introducing a NULL check on media_gt and bailing out early
if so.
While at it, also drop the NULL check for gsc, since it can't be NULL if
media_gt is not NULL.
v2:
- Get address for gsc only after checking that gt is not NULL.
(Shuicheng)
- Drop the NULL check for gsc. (Shuicheng)
v3:
- Add "Fixes" and "Cc: <stable...>" tags. (Matt)

drm/xe/uapi: Reject coh_none PAT index for CPU_ADDR_MIRROR
Add validation in xe_vm_bind_ioctl() to reject PAT indices
with XE_COH_NONE coherency mode when used with
DRM_XE_VM_BIND_FLAG_CPU_ADDR_MIRROR.
CPU address mirror mappings use system memory that is CPU
cached, which makes them incompatible with COH_NONE PAT
indices. Allowing COH_NONE with CPU cached buffers is a
security risk, as the GPU may bypass CPU caches and read
stale sensitive data from DRAM.
Although CPU_ADDR_MIRROR does not create an immediate
mapping, the backing system memory is still CPU cached.
Apply the same PAT coherency restrictions as
DRM_XE_VM_BIND_OP_MAP_USERPTR.
v2:
- Correct fix tag
v6:
- No change
v7:
- Correct fix tag
v8:
- Rebase
v9:
- Limit the restrictions to iGPU
v10:
- Just add the iGPU logic but keep dGPU logic

drm/xe/uapi: Reject coh_none PAT index for CPU cached memory in madvise
Add validation in xe_vm_madvise_ioctl() to reject PAT indices with
XE_COH_NONE coherency mode when applied to CPU cached memory.
Using coh_none with CPU cached buffers is a security issue. When the
kernel clears pages before reallocation, the clear operation stays in
CPU cache (dirty). GPU with coh_none can bypass CPU caches and read
stale sensitive data directly from DRAM, potentially leaking data from
previously freed pages of other processes.
This aligns with the existing validation in vm_bind path
(xe_vm_bind_ioctl_validate_bo).

drm/xe/gsc: Fix BO leak on error in query_compatibility_version()
When xe_gsc_read_out_header() fails, query_compatibility_version()
returns directly instead of jumping to the out_bo label. This skips
the xe_bo_unpin_map_no_vm() call, leaving the BO pinned and mapped
with no remaining reference to free it.
Fix by using goto out_bo so the error path properly cleans up the BO,
consistent with the other error handling in the same function.

drm/xe/eustall: Fix drm_dev_put called before stream disable in close
In xe_eu_stall_stream_close(), drm_dev_put() is called before the
stream is disabled and its resources are freed. If this drops the
last reference, the device structures could be freed while the
subsequent cleanup code still accesses them, leading to a
use-after-free.
Fix this by moving drm_dev_put() after all device accesses are
complete. This matches the ordering in xe_oa_release().

drm/xe: Fix error cleanup in xe_exec_queue_create_ioctl()
Two error handling issues exist in xe_exec_queue_create_ioctl():
1. When xe_hw_engine_group_add_exec_queue() fails, the error path jumps
to put_exec_queue which skips xe_exec_queue_kill(). If the VM is in
preempt fence mode, xe_vm_add_compute_exec_queue() has already added
the queue to the VM's compute exec queue list. Skipping the kill
leaves the queue on that list, leading to a dangling pointer after
the queue is freed.
2. When xa_alloc() fails after xe_hw_engine_group_add_exec_queue() has
succeeded, the error path does not call
xe_hw_engine_group_del_exec_queue() to remove the queue from the hw
engine group list. The queue is then freed while still linked into
the hw engine group, causing a use-after-free.
Fix both by:
- Changing the xe_hw_engine_group_add_exec_queue() failure path to jump
to kill_exec_queue so that xe_exec_queue_kill() properly removes the
queue from the VM's compute list.
- Adding a del_hw_engine_group label before kill_exec_queue for the
xa_alloc() failure path, which removes the queue from the hw engine
group before proceeding with the rest of the cleanup.

drm/xe: Fix dma-buf attachment leak in xe_gem_prime_import()
When xe_dma_buf_init_obj() fails, the attachment from
dma_buf_dynamic_attach() is not detached. Add dma_buf_detach() before
returning the error. Note: we cannot use goto out_err here because
xe_dma_buf_init_obj() already frees bo on failure, and out_err would
double-free it.

drm/xe: Fix bo leak in xe_dma_buf_init_obj() on allocation failure
When drm_gpuvm_resv_object_alloc() fails, the pre-allocated storage bo
is not freed. Add xe_bo_free(storage) before returning the error.
xe_dma_buf_init_obj() calls xe_bo_init_locked(), which frees the bo on
error. Therefore, xe_dma_buf_init_obj() must also free the bo on its own
error paths. Otherwise, since xe_gem_prime_import() cannot distinguish
whether the failure originated from xe_dma_buf_init_obj() or from
xe_bo_init_locked(), it cannot safely decide whether the bo should be
freed.
Add comments documenting the ownership semantics: on success, ownership
of storage is transferred to the returned drm_gem_object; on failure,
storage is freed before returning.
v2: Add comments to explain the free logic.

drm/xe: Fix potential NULL deref in xe_exec_queue_tlb_inval_last_fence_put_unlocked
xe_exec_queue_tlb_inval_last_fence_put_unlocked() uses q->vm->xe as the
first argument to xe_assert(). This function is called unconditionally
from xe_exec_queue_destroy() for all queues, including kernel queues
that have q->vm == NULL (e.g., queues created during GT init in
xe_gt_record_default_lrcs() with vm=NULL).
While current compilers optimize away the q->vm->xe dereference (even
in CONFIG_DRM_XE_DEBUG=y builds, the compiler pushes the dereference
into the WARN branch that is only taken when the assert condition is
false), the code is semantically incorrect and constitutes undefined
behavior in the C abstract machine for the NULL pointer case.
Use gt_to_xe(q->gt) instead, which is always valid for any exec queue.
This is consistent with how xe_exec_queue_destroy() itself obtains the
xe_device pointer in its own xe_assert at the top of the function.

drm/xe/vf: Use drm mm instead of drm sa for CCS read/write
The suballocator algorithm tracks a hole cursor at the last allocation
and tries to allocate after it. This is optimized for fence-ordered
progress, where older allocations are expected to become reusable first.
In fence-enabled mode, that ordering assumption holds. In fence-disabled
mode, allocations may be freed in arbitrary order, so limiting allocation
to the current hole window can miss valid free space and fail allocations
despite sufficient total space.
Use DRM memory manager instead of sub-allocator to get rid of this issue
as CCS read/write operations do not use fences.

drm/xe/debugfs: Correct printing of register whitelist ranges
The register-save-restore debugfs prints whitelist entries as offset
ranges. E.g.,
REG[0x39319c-0x39319f]: allow read access
for a single dword-sized register. However the GENMASK value used to
set the lower bits to '1' for the upper bound of the whitelist range
incorrectly included one more bit than it should have, causing the
whitelist ranges to sometimes appear twice as large as they really were.
For example,
REG[0x6210-0x6217]: allow rw access
was also intended to be a single dword-sized register whitelist (with a
range 0x6210-0x6213) but was printed incorrectly as a qword-sized range
because one too many bits was flipped on. Similar 'off by one' logic
was applied when printing 4-dword register ranges and 64-dword register
ranges as well.
Correct the GENMASK logic to print these ranges in debugfs correctly.
No impact outside of correcting the misleading debugfs output.

ROW_CHICKEN5 is a masked register (i.e., to adjust the value of any of
the lower 16 bits, the corresponding bit in the upper 16 bits must also
be set). Add the XE_REG_OPTION_MASKED to its definition; failure to do
so will cause workaround updates of this register to not apply properly.

drm/xe/tuning: Use proper register offset for GAMSTLB_CTRL
From Xe2 onward (i.e., all platforms officially supported by the Xe
driver), the GAMSTLB_CTRL register is located at offset 0x477C and
represented by the macro "GAMSTLB_CTRL" in code. However the register
formerly resided at offset 0xCF4C on Xe1-era platforms, and we also have
macro XEHP_GAMSTLB_CTRL that represents this old offset in the
unofficial/developer-only Xe1 code. When tuning for the register was
added for Xe3p_LPG, the old Xe1-era macro was accidentally used instead
of the proper macro for Xe2 and beyond, causing the tuning to not be
applied properly. Use the proper definition so that the correct offset
is written to.

drm/xe: Drop registration of guc_submit_wedged_fini from xe_guc_submit_wedge()
xe_guc_submit_wedge() runs in the DMA-fence signaling path, where
GFP_KERNEL memory allocations are not permitted. However, registering
guc_submit_wedged_fini via drmm_add_action_or_reset() triggers such an
allocation.

guc_submit_fini(), where wedged exec queue references are dropped during

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.

drm/xe/pxp: Remove incorrect handling of impossible state during suspend
The default case of the PXP suspend switch is incorrectly exiting
without releasing the lock. However, this case is impossible to hit
because we're switching on an enum and all the valid enum values have
their own cases. 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.

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.

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).
