The correct fix is to tie the global xa entry lifetime to the
queue lifetime: insert in amdgpu_userq_create() and erase in
amdgpu_userq_cleanup(), both at the well-defined doorbell_index key,
making the operation O(1) and resolve the fence driver UAF problem
by binding the userq driver fence to per queue.

Update the way drm_coredump_printer is used based on its documentation
and Xe's code: the main idea is to generate the final version in one go
and then use memcpy to return the chunks requested by the caller of
amdgpu_devcoredump_read.
The generation is moved to a separate worker thread.
This cuts the time to copy the dump from 40s to ~0s on my machine.
---
v3:
- removed adev->coredump_in_progress and instead use work as
the synchronisation mechanism
- use kvfree instead of kfree

MES FW uses address(mqd_addr + sizeof(struct mqd) + 3*sizeof(uint32_t))
as fence address and writes a 32 bit fence value to this address. Driver
needs to allocate some extra memory(at least 4 DWs) in addition to
sizeof(struct mqd) as mqd memory(limited to gfx/compute/sdma queue).
For gfx11/12, sizeof(struct mqd) < PAGE_SIZE, KGD allocates mqd memory with
PAGE_SIZE aligned works. For gfx12.1, sizeof(struct mqd) == PAGE_SIZE,
it doesn't work.
KFD mqd manager hardcodes mqd size to PAGE_SIZE/MQD_SIZE across different
IP versions to solve this issue.
To avoid hardcoding in differnet places and across different IP versions.
Let's use AMDGPU_MQD_SIZE_ALIGN instead. It is used in two places.
1. mqd memory alloction
2. mqd stride handling for multi xcc config
v2: Use AMDGPU_GPU_PAGE_ALIGN. (Mukul)

[Why&How]
Right now, the HDMI HPD filter is enabled by default at 1500ms.
We want to disable it by default, as most modern displays with HDMI do
not require it for DPMS mode.
The HPD can instead be enabled as a driver parameter with a custom delay
value in ms (up to 5000ms).

This patch adds robust reset handling for user queues (userq) to improve
recovery from queue failures. The key components include:
1. Queue detection and reset logic:
- amdgpu_userq_detect_and_reset_queues() identifies failed queues
- Per-IP detect_and_reset callbacks for targeted recovery
- Falls back to full GPU reset when needed
2. Reset infrastructure:
- Adds userq_reset_work workqueue for async reset handling
- Implements pre/post reset handlers for queue state management
- Integrates with existing GPU reset framework
3. Error handling improvements:
- Enhanced state tracking with HUNG state
- Automatic reset triggering on critical failures
- VRAM loss handling during recovery
4. Integration points:
- Added to device init/reset paths
- Called during queue destroy, suspend, and isolation events
- Handles both individual queue and full GPU resets
The reset functionality works with both gfx/compute and sdma queues,
providing better resilience against queue failures while minimizing
disruption to unaffected queues.
v2: add detection and reset calls when preemption/unmaped fails.
add a per device userq counter for each user queue type.(Alex)
v3: make sure we hold the adev->userq_mutex when we call amdgpu_userq_detect_and_reset_queues. (Alex)
warn if the adev->userq_mutex is not held.
v4: make sure we have all of the uqm->userq_mutex held.
warn if the uqm->userq_mutex is not held.
v5: Use array for user queue type counters.(Alex)
all of the uqm->userq_mutex need to be held when calling detect and reset. (Alex)
v6: fix lock dep warning in amdgpu_userq_fence_dence_driver_process
v7: add the queue types in an array and use a loop in amdgpu_userq_detect_and_reset_queues (Lijo)
v8: remove atomic_set(&userq_mgr->userq_count[i], 0).
it should already be 0 since we kzalloc the structure (Alex)
v9: For consistency with kernel queues, We may want something like:
amdgpu_userq_is_reset_type_supported (Alex)

This commit refactors the AMDGPU userqueue management subsystem to replace
IDR (ID Allocation) with XArray for improved performance, scalability, and
maintainability. The changes address several issues with the previous IDR
implementation and provide better locking semantics.
Key changes:
1. **Global XArray Introduction**:
- Added `userq_doorbell_xa` to `struct amdgpu_device` for global queue tracking
- Uses doorbell_index as key for efficient global lookup
- Replaces the previous `userq_mgr_list` linked list approach
2. **Per-process XArray Conversion**:
- Replaced `userq_idr` with `userq_mgr_xa` in `struct amdgpu_userq_mgr`
- Maintains per-process queue tracking with queue_id as key
- Uses XA_FLAGS_ALLOC for automatic ID allocation
3. **Locking Improvements**:
- Removed global `userq_mutex` from `struct amdgpu_device`
- Replaced with fine-grained XArray locking using XArray's internal spinlocks
4. **Runtime Idle Check Optimization**:
- Updated `amdgpu_runtime_idle_check_userq()` to use xa_empty
5. **Queue Management Functions**:
- Converted all IDR operations to equivalent XArray functions:
- `idr_alloc()` → `xa_alloc()`
- `idr_find()` → `xa_load()`
- `idr_remove()` → `xa_erase()`
- `idr_for_each()` → `xa_for_each()`
Benefits:
- **Performance**: XArray provides better scalability for large numbers of queues
- **Memory Efficiency**: Reduced memory overhead compared to IDR
- **Thread Safety**: Improved locking semantics with XArray's internal spinlocks
v2: rename userq_global_xa/userq_xa to userq_doorbell_xa/userq_mgr_xa
Remove xa_lock and use its own lock.
v3: Set queue->userq_mgr = uq_mgr in amdgpu_userq_create()
v4: use xa_store_irq (Christian)
hold the read side of the reset lock while creating/destroying queues and the manager data structure. (Chritian)

The Constant Engine found on gfx6-gfx10 HW has been a notorious source of
problems.
RADV never used it in the first place, radeonsi only used it for a few
releases around 2017 for gfx6-gfx9 before dropping support for it as
well.
While investigating another problem I just recently found that submitting
to the CE seems to be completely broken on gfx9 for quite a while.
Since nobody complained about that problem it most likely means that
nobody is using any of the affected radeonsi versions on current Linux
kernels any more.
So to potentially phase out the support for the CE and eliminate another
source of problems block submitting CE IBs unless it is enabled again
using a debug flag.

Add mmio_remap bookkeeping to amdgpu_device and introduce
amdgpu_ttm_mmio_remap_bo_init()/fini() to manage a kernel-owned,
one-page (4K) BO in AMDGPU_GEM_DOMAIN_MMIO_REMAP.
Bookkeeping:
- adev->rmmio_remap.bo : kernel-owned singleton BO
The BO is allocated during TTM init when a remap bus address is available
(adev->rmmio_remap.bus_addr) and PAGE_SIZE <= AMDGPU_GPU_PAGE_SIZE (4K),
and freed during TTM fini.
v2:
- Check mmio_remap bus address (adev->rmmio_remap.bus_addr) instead of
rmmio_base. (Alex)
- Skip quietly if PAGE_SIZE > AMDGPU_GPU_PAGE_SIZE or no bus address
(no warn). (Alex)
- Use `amdgpu_bo_create()` (not *_kernel) - Only with this The object
is stored in adev->mmio_remap.bo and will later be exposed to
userspace via a GEM handle. (Christian)
v3:
- Remove obvious comment before amdgpu_ttm_mmio_remap_bo_fini() call.

During a DPC error kernel waits for the link to be active before
notifying downstream devices. On certain platforms with Broadcom switch
in synthetiic mode, switch responds with values even though the link is
not fully ready. The config space restoration done by pcie port driver
for SWUS/DS of dGPU is thus not effective as the switch is still doing
internal enumeration.
As a workaround, save state of SWUS/DS device in driver. Add additional
check to see if link is active and restore the values during DPC error
callbacks.
