[PATCH 00/20] Intel Xe GPU Debug Support (eudebug) v5

[Mika Kuoppala]

Hi,

This is the v5 patch series for Intel Xe GPU debug support (eudebug).

As the initial feedback on v4 was positive, we brought the
rest of the features from v3, namely the page fault support
into this series.

This series continues from the following previous submissions:
- v1: https://lists.freedesktop.org/archives/intel-xe/2024-July/043605.html
- v2: https://lists.freedesktop.org/archives/intel-xe/2024-October/052260.html
- v3: https://lists.freedesktop.org/archives/intel-xe/2024-December/061476.html
- v4: https://lists.freedesktop.org/archives/intel-xe/2025-August/091645.html

Known shortcomings: With multiple debug clients page faults can
race into how attention polling is stopped/started and lead to
missing attentions.

# Major Changes from v4

v4 omitted page fault support, it is reworked from v3 and included
in this series.

### Major Changes from v3

#### 1. Elimination of ptrace_may_access() and pid

In previous series, the connection attempt was made using the process ID
(PID) as the target. Access was checked using the `ptrace_may_access()`
helper to achieve security parity with CPU-side debugging.

In v4, this has been changed to connect to a DRM client, using a file
descriptor as the target. This approach eliminates the need for the
`ptrace_may_access()` symbol export, as access control is now managed
through the debugger process's access to the file descriptor. For example,
accessing a remote DRM client requires the debugger process to
successfully call `pidfd_getfd()` to obtain a duplicate of the target
file descriptor.The 1:1 mapping between DRM clients and their debuggers
eliminates the need for `EVENT_OPEN` and simplifies overall connection
tracking.

#### 2. ELF binaries not held in kernel memory

In v4, debug data is delivered as a VM bind 'OP_ADD_DEBUG_DATA' extension.
The ELF binaries are no longer stored within the Xe KMD but are instead
kept in a file. The file path is passed as part of an extension in
the newly introduced 'OP_ADD_DEBUG_DATA' VM bind operation. Alternatively
pseudo-paths can be used to annotate special address ranges similar to
/proc/<pid>/maps.

#### 3. Debug metadata not carried in VMA struct

Instead of attaching debug data to vma created by 'OP_MAP',
we introduce separate ops for managing the metadata.
Debug data is no longer held in the VMA struct. xe_vm contains a
list of all associated debug data.

#### 4. Reading debug data via debugfs

This revision introduces the possibility to access debug data using per
client debugfs entries. The intent was to achieve similar interface to
'/proc/<pid>/maps'

[PATCH 01/20] drm/xe/eudebug: Introduce eudebug interface

[Mika Kuoppala]

This patch adds the eudebug interface to the Xe driver, enabling
user-space debuggers (e.g., GDB) to track and interact with GPU resources
of a DRM client. Debuggers can inspect or modify these resources,
for example, to locate ISA/ELF sections and install breakpoints in a
shader's instruction stream.

A debugger opens a connection to the Xe driver via a DRM ioctl, specifying
the target DRM client's file descriptor. This returns an anonymous file
descriptor for the connection, which can be used to listen for resource
creation/destruction events. The same file descriptor can also be used to
receive hardware state change events and control execution flow by
interrupting EU threads on the GPU (in follow-up patches).

This patch introduces the eudebug connection and event queuing,
adding client create/destroy and VM create/destroy events as a baseline.
Additional events and hardware control for full debugger operation are
needed and will be introduced in follow-up patches.

The resource tracking components are inspired by Maciej Patelczyk's work on
resource handling for i915. Chris Wilson suggested a two-way mapping
approach, which simplifies using the resource map as definitive
bookkeeping forresources relayed to the debugger during the discovery
phase (in a follow-up patch).

v2: - Kconfig support (Matthew)
    - ptraced access control (Lucas)
    - pass expected event length to user (Zbigniew)
    - only track long running VMs
    - checkpatch (Tilak)
    - include order (Andrzej)
    - 32bit fixes (Andrzej)
    - cleaner get_task_struct
    - remove xa_array and use clients.list for tracking (Mika)

v3: - adapt to removal of clients.lock (Mika)
    - create_event cleanup (Christoph)

v4: - add proper header guards (Christoph)
    - better read_event fault handling (Christoph, Mika)
    - simplify attach (Mika)
    - connect using target file descriptors
    - avoid event->seqno after queue as it is can UAF (Mika)
    - use drmm for eudebug_fini (Maciej)
    - squash dynamic enable

[PATCH 02/20] drm/xe/eudebug: Introduce discovery for resources

[Mika Kuoppala]

A debugger connection can occur after a client has created and destroyed an
arbitrary number of resources. To support this, we need to relay all
currently existing resources to the debugger. The client is held on selected
ioctls until this discovery process, executed by a workqueue, is complete.

This patch is based on discovery work by Maciej Patelczyk for the i915 driver.

v2: - use rw_semaphore to block DRM ioctls during discovery (Matthew)
    - only lock according to ioctl at play (Dominik)

v4: - s/discovery_lock/ioctl_lock
    - change lock to be per xe_file as is connections

[PATCH 03/20] drm/xe/eudebug: Introduce exec_queue events

[Mika Kuoppala]

From: Dominik Grzegorzek <dominik.grzegorzek@intel.com>

Add events to inform the debugger about the creation and destruction of
exec_queues. Use user engine class types instead of the internal
xe_engine_class enum in exec_queue events. During discovery, only advertise
exec_queues with render or compute class,excluding others.

v2: - Only track long running queues
    - Checkpatch (Tilak)
v3: __counted_by added
v4: - use helpers for filtering engines (Mika)

[PATCH 04/20] drm/xe: Add EUDEBUG_ENABLE exec queue property

[Mika Kuoppala]

From: Dominik Grzegorzek <dominik.grzegorzek@intel.com>

This patch introduces an immutable eudebug property for exec_queues,
using a flags value to enable eudebug-specific features. For now, the
engine LRC uses this flag to enable the runalone hardware feature.
Runalone ensures that only one hardware engine in a group
[rcs0, ccs0-3] is active on a tile.

v2: - check CONFIG_DRM_XE_EUDEBUG and LR mode (Matthew)
    - disable preempt (Dominik)
    - lrc_create remove from engine init

[PATCH 05/20] drm/xe: Introduce ADD_DEBUG_DATA and REMOVE_DEBUG_DATA vm bind ops

[Mika Kuoppala]

From: Christoph Manszewski <christoph.manszewski@intel.com>

Make it possible to add and remove per vm debug data, which can be used
to annotate vm ranges (using pseudopaths) or to associate them with
a file which can carry arbitrary debug data (e.g. binary instruction to
code line mapping). The debug data is kept separe from the vmas. Each
address can be associated with only one debug data entry i.e. debug data
entries cannot overlap. Each entry is atomic so to remove it the
creation address and range has to be passed for removal.

For debug data manipulation only the 'op' and 'extensions' field from
'struct drm_xe_vm_bind_op' is used. All required parameters are passed
through 'struct drm_xe_vm_bind_op_ext_debug_data' and a valid instance
should be present in the extension chain pointed by the 'extensions'
field.

Debug data will be accessible through the eudebug event interface,
introduced in the following patch. An alternative way to access debug data
using debugfs, without relying on eudebug, will be proposed as a follow-up
to the eudebug series.

[PATCH 06/20] drm/xe/eudebug: Introduce vm bind and vm bind debug data events

[Mika Kuoppala]

From: Christoph Manszewski <christoph.manszewski@intel.com>

This patch adds events to track the bind ioctl and associated debug data add
and remove operations. As a single bind can involve multiple operations and
may fail mid-process, events are stored until the full chain of operations
succeeds before relaying to the debugger. If no debug data operations occur,
no events are sent to avoid unnecessary debugger notifications.

v2: always end bind sequence on error (Mika, Maciej)

[PATCH 07/20] drm/xe/eudebug: Add UFENCE events with acks

[Mika Kuoppala]

When vma is in place, debugger needs to intercept before
userspace proceeds with the workload. For example to install
a breakpoint in a eu shader.

Attach debugger in xe_user_fence, send UFENCE event
and stall normal user fence signal path to yield if
there is debugger attached to ufence.

When ack (ioctl) is received for the corresponding seqno,
signal ufence.

v2: - return err instead of 0 to guarantee signalling (Dominik)
    - checkpatch (Tilak)
    - Kconfig (Mika, Andrzej)
    - use lock instead of cmpxchg (Mika)
v4: - improve ref handling and no ufences nodebug binds
v5: - remove overzealous warn_on on bind_ref_seqno (Christoph)
    - remove superfluous signalled (Mika)
    - fix double free on bind sequence (Mika)
    - Dont fill op fields if no debugger (Maciej)

[PATCH 08/20] drm/xe/eudebug: vm open/pread/pwrite

[Mika Kuoppala]

Debugger needs access to the client's vm to read and write. For
example inspecting ISA/ELF and setting up breakpoints.

Add ioctl to open target vm with debugger client and vm_handle
and hook up pread/pwrite possibility.

Open will take timeout argument so that standard fsync
can be used for explicit flushing between cpu/gpu for
the target vm.

Implement this for bo backed storage. userptr will
be done in following patch.

v2: - checkpatch (Maciej)
    - 32bit fixes (Andrzej)
    - bo_vmap (Mika)
    - fix vm leak if can't allocate k_buffer (Mika)
    - assert vm write held for vma (Matthew)

v3: - fw ref, ttm_bo_access
    - timeout boundary check (Dominik)
    - dont try to copy to user on zero bytes (Mika)

v4: - offset as unsigned long (Thomas)
    - check XE_VMA_DESTROYED

v5: drm_dev_put before releasing debugger (Mika)

[PATCH 09/20] drm/xe/eudebug: userptr vm pread/pwrite

[Mika Kuoppala]

Implement debugger vm access for userptrs.

When bind is done, take ref to current task so that
we know from which vm the address was bound. Then during
debugger pread/pwrite we use this target task as
parameter to access the debuggee vm with access_process_vm().

This is based on suggestions from Simona, Thomas and Joonas.

v2: need to add offset into vma (Dominik)
v3: move code into xe_userptr.c (Mika)

[PATCH 10/20] drm/xe/eudebug: hw enablement for eudebug

[Mika Kuoppala]

From: Dominik Grzegorzek <dominik.grzegorzek@intel.com>

In order to turn on debug capabilities, (i.e. breakpoints), TD_CTL
and some other registers needs to be programmed. Implement eudebug
mode enabling including eudebug related workarounds.

v2: Move workarounds to xe_wa_oob. Use reg_sr directly instead of
xe_rtp as it suits better for dynamic manipulation of those register we

[PATCH 11/20] drm/xe/eudebug: Introduce EU control interface

[Mika Kuoppala]

From: Dominik Grzegorzek <dominik.grzegorzek@intel.com>

Introduce EU control functionality, which allows EU debugger
to interrupt, resume, and inform about the current state of
EU threads during execution. Provide an abstraction layer,
so in the future guc will only need to provide appropriate callbacks.

Based on implementation created by authors and other folks within
i915 driver.

v2: - checkpatch (Maciej)
    - lrc index off by one fix (Mika)
    - checkpatch (Tilak)
    - 32bit fixes (Andrzej, Mika)
    - find_resource_get for client (Mika)

v3: - fw ref (Mika)
    - attention register naming

v4: - fused off handling (Dominik)
    - squash xe3 parts and ptl attentions (Mika)

[PATCH 12/20] drm/xe/eudebug: Introduce per device attention scan worker

[Mika Kuoppala]

From: Dominik Grzegorzek <dominik.grzegorzek@intel.com>

Scan for EU debugging attention bits periodically to detect if some EU
thread has entered the system routine (SIP) due to EU thread exception.

Make the scanning interval 10 times slower when there is no debugger
connection open. Send attention event whenever we see attention with
debugger presence. If there is no debugger connection active - reset.

Based on work by authors and other folks who were part of attentions in
i915.

v2: - use xa_array for files
    - null ptr deref fix for non-debugged context (Dominik)
    - checkpatch (Tilak)
    - use discovery_lock during list traversal

v3: - engine status per gen improvements, force_wake ref
    - __counted_by (Mika)

v4: - attention register naming (Dominik)

[PATCH 14/20] drm/xe: Implement SR-IOV and eudebug exclusivity

[Mika Kuoppala]

From: Christoph Manszewski <christoph.manszewski@intel.com>

EU debug functionality relies on access to specific mmio registers.
Since VFs don't have access to those registers and in order to avoid
interference with VFs, make SR-IOV and eudebug functionality exclusive.
I.e. don't allow to enable eudebug in VF mode and don't allow to enable
eudebug when any VFs are provisioned. Likewise, don't allow to provision
VFs when eudebug is enabled.

[PATCH 15/20] drm/xe: Add xe_client_debugfs and introduce debug_data file

[Mika Kuoppala]

From: Christoph Manszewski <christoph.manszewski@intel.com>

Create a debug_data file for each xe file/client which is supposed to
list all mapped debug data and attempts to mimic '/proc/pid/maps'.
Each line represents a single mapping and has the following format:

  <vm id> <begin>-<end> <flags> <offset> <pathname>

Add xe_eu_attentions structure to capture and store eu attention bits.
Add a function to count the number of eu threads that have turned on from
eu attentions, and add a function to count the number of eu threads that
have changed on a state between eu attentions.

[PATCH 18/20] drm/xe/eudebug: Introduce EU pagefault handling interface

[Mika Kuoppala]

From: Gwan-gyeong Mun <gwan-gyeong.mun@intel.com>

The XE2 (and PVC) HW has a limitation that the pagefault due to invalid
access will halt the corresponding EUs. To solve this problem, introduce
EU pagefault handling functionality, which allows to unhalt pagefaulted
eu threads and to EU debugger to get inform about the eu attentions state
of EU threads during execution.

If a pagefault occurs, send the DRM_XE_EUDEBUG_EVENT_PAGEFAULT event
after handling the pagefault. The pagefault eudebug event follows
the newly added drm_xe_eudebug_event_pagefault type.
When a pagefault occurs, it prevents to send the
DRM_XE_EUDEBUG_EVENT_EU_ATTENTION event to the client during pagefault
handling.

The page fault event delivery follows the below policy.
(1) If EU Debugger discovery has completed and pagefaulted eu threads turn
    on attention bit then pagefault handler delivers pagefault event
    directly.
(2) If a pagefault occurs during eu debugger discovery process, pagefault
    handler queues a pagefault event and sends the queued event when
    discovery has completed and pagefaulted eu threads turn on attention
    bit.
(3) If the pagefaulted eu thread struggles to turn on the attention bit
    within the specified time, the attention scan worker sends a pagefault
    event when it detects that the attention bit is turned on.

If multiple eu threads are running and a pagefault occurs due to accessing
the same invalid address, send a single pagefault event
(DRM_XE_EUDEBUG_EVENT_PAGEFAULT type) to the user debugger instead of a
pagefault event for each of the multiple eu threads.
If eu threads (other than the one that caused the page fault before) access
the new invalid addresses, send a new pagefault event.

As the attention scan worker send the eu attention event whenever the
attention bit is turned on, user debugger receives attenion event
immediately after pagefault event.
In this case, the page-fault event always precedes the attention event.

When the user debugger receives an attention event after a pagefault event,
it can detect whether additional breakpoints or interrupts occur in
addition to the existing pagefault by comparing the eu threads where the
pagefault occurred with the eu threads where the attention bit is newly
enabled.

v2: use only force exception (Joonas, Mika)
v3: rebased on v4 (Mika)

[PATCH 19/20] drm/xe/vm: Support for adding null page VMA to VM on request

[Mika Kuoppala]

From: Gwan-gyeong Mun <gwan-gyeong.mun@intel.com>

The XE2 (and PVC) HW has a limitation that the pagefault due to invalid
access will halt the corresponding EUs. So, in order to activate the
debugger, kmd needs to install the temporal page to unhalt the EUs.
Plan to be used for pagefault handling when the EU debugger is running.
The idea is to install a null page vma if the pagefault is from an invalid
access. After installing null page pte, the user debugger can continue to
run/inspect without causing a fatal failure or reset and stop.
Based on Bruce's implementation [1].

[PATCH 20/20] drm/xe/eudebug: Enable EU pagefault handling

[Mika Kuoppala]

From: Gwan-gyeong Mun <gwan-gyeong.mun@intel.com>

The XE2 (and PVC) HW has a limitation that the pagefault due to invalid
access will halt the corresponding EUs. To solve this problem, enable
EU pagefault handling functionality, which allows to unhalt pagefaulted
eu threads and to EU debugger to get inform about the eu attentions state
of EU threads during execution.

If a pagefault occurs, send the DRM_XE_EUDEBUG_EVENT_PAGEFAULT event
after handling the pagefault.

The pagefault handling is a mechanism that allows a stalled EU thread to
enter SIP mode by installing a temporal null page to the page table entry
where the pagefault happened.

A brief description of the page fault handling mechanism flow between KMD
and the eu thread is as follows

(1) eu thread accesses unallocated address
(2) pagefault happens and eu thread stalls
(3) XE kmd set an force eu thread exception to allow the running eu thread
    to enter SIP mode (kmd set ForceException / ForceExternalHalt bit of
    TD_CTL register)
    Not stalled (none-pagefaulted) eu threads enter SIP mode
(4) XE kmd installs temporal null page to the pagetable entry of the
    address where pagefault happened.
(5) XE kmd replies pagefault successful message to GUC
(6) stalled eu thread resumes as per pagefault condition has resolved
(7) resumed eu thread enters SIP mode due to force exception set by (3)

As designed this feature to only work when eudbug is enabled, it should
have no impact to regular recoverable pagefault code path.

BUT SEE:

   do {} while (0) advice is over-stated in a few situations:

   The more obvious case is macros, like MODULE_PARM_DESC, invoked at
   file-scope, where C disallows code (it must be in functions).  See
   $exceptions if you have one to add by name.

   More troublesome is declarative macros used at top of new scope,
   like DECLARE_PER_CPU.  These might just compile with a do-while-0
   wrapper, but would be incorrect.  Most of these are handled by
   detecting struct,union,etc declaration primitives in $exceptions.

   Theres also macros called inside an if (block), which "return" an
   expression.  These cannot do-while, and need a ({}) wrapper.

   Enjoy this qualification while we work to improve our heuristics.

BUT SEE:

   do {} while (0) advice is over-stated in a few situations:

   The more obvious case is macros, like MODULE_PARM_DESC, invoked at
   file-scope, where C disallows code (it must be in functions).  See
   $exceptions if you have one to add by name.

   More troublesome is declarative macros used at top of new scope,
   like DECLARE_PER_CPU.  These might just compile with a do-while-0
   wrapper, but would be incorrect.  Most of these are handled by
   detecting struct,union,etc declaration primitives in $exceptions.

   Theres also macros called inside an if (block), which "return" an
   expression.  These cannot do-while, and need a ({}) wrapper.

   Enjoy this qualification while we work to improve our heuristics.

Maybe an xe_gt_assert here instead.

I would double check with the GuC team if you have have enable EU
debugging on each guc_id in multi-lrc contexts. I suspect not given
register, scheduling toggles, and deregister H2G operate only on the
main GuC ID. I'm am however unsure as H2G 8006 is not in GuC spec I'm
looking at.

The above code looks unused as LRC is always NULL.

The return value is not checked at the caller, so NULL return would be
better choice.

I'd probably stick this implementation xe_guc_submit.c as even though
this EU debug specific, IMO you don't really need to compile this part
out as surely if EU kconfig is unset EXEC_QUEUE_EUDEBUG_FLAG_ENABLE
would be clear. Maybe ask others about where to stick this, as my
opinion on this isn't strong either way.

Not a full review, it will take me a minute to wrap my head around what
this doing but if a user application has SVM enabled the VMA lookup will
never fail as the entire VMA space is always populated by either valid
VMAs with bindings or VMAs which indicate the CPU address space is being
mirrored. The latter doesn't mean that CPU address exists though - the
xe_svm.c layer figures that out. I suspect you are missing some logic to
properly handle EU debug + SVM.

Let try to wrap my head around exactly what the EU debug pagefault code
is doing.

[PATCH 16/20] drm/xe/eudebug: Mark guc contexts as debuggable

[Mika Kuoppala]

We need to inform to guc which contexts are debuggable
as their handling is different from ordinary contexts.

v2: void return, use xe_gt_dbg, no need for lrc (Matt)

[Mika Kuoppala]

We need to inform to guc which contexts are debuggable
as their handling is different from ordinary contexts.

v2: void return, use xe_gt_dbg, no need for lrc (Matt)
v3: add the workaround enabling (Daniele)
v4: version needed to 70.49.4

We usually prefer to use gt_info for specific features needing a certain 
GuC version (see e.g. is_engine_activity_supported()), since there is 
already a warn-level message at GuC fetch time recommending a new enough 
version of the GuC

nit: we usually don't use the "xe_" prefix for static functions (below 
as well)

I think this should be gt_err and not dbg because it has info that we 
would want even if debug logs are disabled.

This seems to be silently dropping the setting. If I'm not missing 
anything, this means that if an app tries to enable debug on a context 
on a too old GuC it won't receive any actual error return and the only 
way the user has to know that something went wrong is to look at the 
driver load logs in dmesg. IMO we should either escalate an error from 
here (which would require de-registering the queue) or have a guc 
version check much earlier in the debuggable queue creation flow and 
fail there.

If the other log is raised to gt_err then this one can be dropped.

Looking at the WA details this seems to start at 2001.
