drm/i915: skip __i915_request_skip() for already signaled requests
After a GPU reset the HWSP is zeroed, so previously completed
requests appear incomplete. If such a request is picked up during
reset_rewind() and marked guilty, i915_request_set_error_once()
returns early (fence already signaled), leaving fence.error without
a fatal error code. The subsequent __i915_request_skip() then hits:
```
GEM_BUG_ON(!fatal_error(rq->fence.error))
```
Fixes a kernel BUG observed on Sandy Bridge (Gen6) during
heartbeat-triggered engine resets.
```
kernel BUG at drivers/gpu/drm/i915/i915_request.c:556!
RIP: __i915_request_skip+0x15e/0x1d0 [i915]
...
__i915_request_reset+0x212/0xa70 [i915]
reset_rewind+0xe4/0x280 [i915]
intel_gt_reset+0x30d/0x5b0 [i915]
heartbeat+0x516/0x530 [i915]
```
Guard __i915_request_skip() with i915_request_signaled(), if the
fence is already signaled, the ring content is committed and there
is nothing left to skip.
Fixes:

drm/i915/gt: fix refcount underflow in intel_engine_park_heartbeat
A use-after-free / refcount underflow is possible when the heartbeat
worker and intel_engine_park_heartbeat() race to release the same
engine->heartbeat.systole request.
The heartbeat worker reads engine->heartbeat.systole and calls
i915_request_put() on it when the request is complete, but clears
the pointer in a separate, non-atomic step. Concurrently, a request
retirement on another CPU can drop the engine wakeref to zero, triggering
__engine_park() -> intel_engine_park_heartbeat(). If the heartbeat
timer is pending at that point, cancel_delayed_work() returns true and
intel_engine_park_heartbeat() reads the stale non-NULL systole pointer
and calls i915_request_put() on it again, causing a refcount underflow:

```
Fix this by replacing the non-atomic pointer read + separate clear with
xchg() in both racing paths. xchg() is a single indivisible hardware
instruction that atomically reads the old pointer and writes NULL. This
guarantees only one of the two concurrent callers obtains the non-NULL
pointer and performs the put, the other gets NULL and skips it.

drm/i915: replace use of system_unbound_wq with system_dfl_wq
Currently if a user enqueue a work item using schedule_delayed_work() the
used wq is "system_wq" (per-cpu wq) while queue_delayed_work() use
WORK_CPU_UNBOUND (used when a cpu is not specified). The same applies to
schedule_work() that is using system_wq and queue_work(), that makes use
again of WORK_CPU_UNBOUND.
This lack of consistency cannot be addressed without refactoring the API.
system_unbound_wq should be the default workqueue so as not to enforce
locality constraints for random work whenever it's not required.
This patch continues the effort to refactor worqueue APIs, which has
begun with the change introducing new workqueues:

drm/{i915, xe}/reg: rename masked field helpers REG_MASKED_FIELD*()
The underscore prefixed masked field helper names aren't great. Rename them REG_MASKED_FIELD(), REG_MASKED_FIELD_ENABLE(), and REG_MASKED_FIELD_DISABLE(). This is more in line with the existing REG_FIELD_PREP() etc. helpers, and using "field" instead of "bit" is more accurate for the functionality. This is done with: sed -i 's/_MASKED_FIELD/REG_MASKED_FIELD/g' $(git grep -wl _MASKED_FIELD) sed -i 's/_MASKED_BIT_ENABLE/REG_MASKED_FIELD_ENABLE/g' $(git grep -wl _MASKED_BIT_ENABLE) sed -i 's/_MASKED_BIT_DISABLE/REG_MASKED_FIELD_DISABLE/g' $(git grep -wl _MASKED_BIT_DISABLE) with some manual indentation fixes on top.

dma-buf: abstract fence locking v2
Add dma_fence_lock_irqsafe() and dma_fence_unlock_irqrestore() wrappers
and mechanically apply them everywhere.
Just a pre-requisite cleanup for a follow up patch.
v2: add some missing i915 bits, add abstraction for lockdep assertion as
well

Convert more 'alloc_obj' cases to default GFP_KERNEL arguments
This converts some of the visually simpler cases that have been split over multiple lines. I only did the ones that are easy to verify the resulting diff by having just that final GFP_KERNEL argument on the next line. Somebody should probably do a proper coccinelle script for this, but for me the trivial script actually resulted in an assertion failure in the middle of the script. I probably had made it a bit _too_ trivial. So after fighting that far a while I decided to just do some of the syntactically simpler cases with variations of the previous 'sed' scripts. The more syntactically complex multi-line cases would mostly really want whitespace cleanup anyway. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> |

Convert 'alloc_flex' family to use the new default GFP_KERNEL argument
This is the exact same thing as the 'alloc_obj()' version, only much smaller because there are a lot fewer users of the *alloc_flex() interface. As with alloc_obj() version, this was done entirely with mindless brute force, using the same script, except using 'flex' in the pattern rather than 'objs*'.

Convert 'alloc_obj' family to use the new default GFP_KERNEL argument
This was done entirely with mindless brute force, using
git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' |
xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/'
to convert the new alloc_obj() users that had a simple GFP_KERNEL
argument to just drop that argument.
Note that due to the extreme simplicity of the scripting, any slightly
more complex cases spread over multiple lines would not be triggered:
they definitely exist, but this covers the vast bulk of the cases, and
the resulting diff is also then easier to check automatically.
For the same reason the 'flex' versions will be done as a separate
conversion.

treewide: Replace kmalloc with kmalloc_obj for non-scalar types
This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook <kees@kernel.org> |

kernel.h: drop STACK_MAGIC macro
Patch series "Unload linux/kernel.h", v5. kernel.h hosts declarations that can be placed better. This series decouples kernel.h with some explicit and implicit dependencies; also, moves tracing functionality to a new independent header. This patch (of 6): The macro was introduced in 1994, v1.0.4, for stacks protection. Since that, people found better ways to protect stacks, and now the macro is only used by i915 selftests. Move it to a local header and drop from the kernel.h.

drm/i915/gt: use designated initializers for intel_gt_debugfs_file
CONFIG_RANDSTRUCT may reorder structure fields, which makes positional initializers unsafe. The i915 GT debugfs tables were using positional initializers for `struct intel_gt_debugfs_file`, and on configs where the layout differs (e.g., presence/absence of the `.eval` callback), this can lead to fields being initialized incorrectly and trigger randstruct warnings such as: ``` drivers/gpu/drm/i915/gt/intel_gt_debugfs.c:75:51: note: randstruct: casting between randomized structure pointer types (constructor) ``` Switch all the GT debugfs file arrays to designated initializers. This binds each value to the intended member regardless of structure reordering or optional members and removes the warning while preserving the intended initialization. Also drops the '&' from intel_eval_slpc_support so .eval receives the function pointer directly. No functional change, only initialization style is updated.

PCI: Fix restoring BARs on BAR resize rollback path
BAR resize operation is implemented in the pci_resize_resource() and
pbus_reassign_bridge_resources() functions. pci_resize_resource() can be
called either from __resource_resize_store() from sysfs or directly by the
driver for the Endpoint Device.
The pci_resize_resource() requires that caller has released the device
resources that share the bridge window with the BAR to be resized as
otherwise the bridge window is pinned in place and cannot be changed.
pbus_reassign_bridge_resources() rolls back resources if the resize
operation fails, but rollback is performed only for the bridge windows.
Because releasing the device resources are done by the caller of the BAR
resize interface, these functions performing the BAR resize do not have
access to the device resources as they were before the resize.
pbus_reassign_bridge_resources() could try __pci_bridge_assign_resources()
after rolling back the bridge windows as they were, however, it will not
guarantee the resource are assigned due to differences in how FW and the
kernel assign the resources (alignment of the start address and tail).
To perform rollback robustly, the BAR resize interface has to be altered to
also release the device resources that share the bridge window with the BAR
to be resized.
Also, remove restoring from the entries failed list as saved list should
now contain both the bridge windows and device resources so the extra
restore is duplicated work.
Some drivers (currently only amdgpu) want to prevent releasing some
resources. Add exclude_bars param to pci_resize_resource() and make amdgpu
pass its register BAR (BAR 2 or 5), which should never be released during
resize operation. Normally 64-bit prefetchable resources do not share a
bridge window with the 32-bit only register BAR, but there are various
fallbacks in the resource assignment logic which may make the resources
share the bridge window in rare cases.
This change (together with the driver side changes) is to counter the
resource releases that had to be done to prevent resource tree corruption
in the ("PCI: Release assigned resource before restoring them") change. As
such, it likely restores functionality in cases where device resources were
released to avoid resource tree conflicts which appeared to be "working"
when such conflicts were not correctly detected by the kernel.

drm/i915: split out separate files for jiffies timeout and wait helpers
Add i915_jiffies.h and intel_display_jiffies.h for jiffies timeout and wait helpers, and use them separately from i915 and display. This helps reduce the display dependency on i915_utils.h. Long term, both msecs_to_jiffies_timeout() and wait_remaining_ms_from_jiffies() really belong in core kernel headers, but for now unblock display refactoring.

drm/i915/gt: Use standard API for seqcount read in TLB invalidation
seqprop_sequence() is not intended for use outside seqlock.h. Although it is accessible as a macro, it is meant to be used only internally within the header. Replace it with its proper wrapper, raw_read_seqcount().
