Merge tag 'drm-next-2024-01-10' of git://anongit.freedesktop.org/drm/drm

Pull drm updates from Dave Airlie:
 "This contains two major new drivers:

   - imagination is a first driver for Imagination Technologies devices,
     it only covers very specific devices, but there is hope to grow it

   - xe is a reboot of the i915 GPU (shares display) side using a more
     upstream focused development model, and trying to maximise code
     sharing. It's not enabled for any hw by default, and will hopefully
     get switched on for Intel's Lunarlake.

  This also drops a bunch of the old UMS ioctls. It's been dead long
  enough.

  amdgpu has a bunch of new color management code that is being used in
  the Steam Deck.

  amdgpu also has a new ACPI WBRF interaction to help avoid radio
  interference.

  Otherwise it's the usual lots of changes in lots of places.

fb46e22a9e Many singleton patches against the MM code. The patch series which
are included in this merge do the following:
 
 - Peng Zhang has done some mapletree maintainance work in the
   series
 
 	"maple_tree: add mt_free_one() and mt_attr() helpers"
 	"Some cleanups of maple tree"
 
 - In the series "mm: use memmap_on_memory semantics for dax/kmem"
   Vishal Verma has altered the interworking between memory-hotplug
   and dax/kmem so that newly added 'device memory' can more easily
   have its memmap placed within that newly added memory.
 
 - Matthew Wilcox continues folio-related work (including a few
   fixes) in the patch series
 
 	"Add folio_zero_tail() and folio_fill_tail()"
 	"Make folio_start_writeback return void"
 	"Fix fault handler's handling of poisoned tail pages"
 	"Convert aops->error_remove_page to ->error_remove_folio"
 	"Finish two folio conversions"
 	"More swap folio conversions"
 
 - Kefeng Wang has also contributed folio-related work in the series
 
 	"mm: cleanup and use more folio in page fault"
 
 - Jim Cromie has improved the kmemleak reporting output in the
   series "tweak kmemleak report format".
 
 - In the series "stackdepot: allow evicting stack traces" Andrey
   Konovalov to permits clients (in this case KASAN) to cause
   eviction of no longer needed stack traces.

5e0a760b44 mm, treewide: rename MAX_ORDER to MAX_PAGE_ORDER
commit 23baf831a3 ("mm, treewide: redefine MAX_ORDER sanely") has
changed the definition of MAX_ORDER to be inclusive.  This has caused
issues with code that was not yet upstream and depended on the previous

Merge tag 'vfs-6.8.misc' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs

Pull misc vfs updates from Christian Brauner:
 "This contains the usual miscellaneous features, cleanups, and fixes
  for vfs and individual fses.

  Features:

   - Add Jan Kara as VFS reviewer

   - Show correct device and inode numbers in proc/<pid>/maps for vma
     files on stacked filesystems. This is now easily doable thanks to
     the backing file work from the last cycles. This comes with
     selftests

  Cleanups:

   - Remove a redundant might_sleep() from wait_on_inode()

   - Initialize pointer with NULL, not 0

   - Clarify comment on access_override_creds()

   - Rework and simplify eventfd_signal() and eventfd_signal_mask()
     helpers

   - Process aio completions in batches to avoid needless wakeups

   - Completely decouple struct mnt_idmap from namespaces. We now only
     keep the actual idmapping around and don't stash references to
     namespaces

   - Reformat maintainer entries to indicate that a given subsystem
     belongs to fs/

   - Simplify fput() for files that were never opened

   - Get rid of various pointless file helpers

   - Rename various file helpers

   - Rename struct file members after SLAB_TYPESAFE_BY_RCU switch from
     last cycle

   - Make relatime_need_update() return bool

   - Use GFP_KERNEL instead of GFP_USER when allocating superblocks

   - Replace deprecated ida_simple_*() calls with their current ida_*()
     counterparts

  Fixes:

   - Fix comments on user namespace id mapping helpers. They aren't
     kernel doc comments so they shouldn't be using /**

   - s/Retuns/Returns/g in various places

   - Add missing parameter documentation on can_move_mount_beneath()

   - Rename i_mapping->private_data to i_mapping->i_private_data

   - Fix a false-positive lockdep warning in pipe_write() for watch
     queues

   - Improve __fget_files_rcu() code generation to improve performance

   - Only notify writer that pipe resizing has finished after setting
     pipe->max_usage otherwise writers are never notified that the pipe
     has been resized and hang

   - Fix some kernel docs in hfsplus

   - s/passs/pass/g in various places

   - Fix kernel docs in ntfs

   - Fix kcalloc() arguments order reported by gcc 14

   - Fix uninitialized value in reiserfs"

This function may copy the pad0 field of struct hl_info_sec_attest to user
mode which has not been initialized, resulting in leakage of kernel heap

bc5f15abcf accel/habanalabs/gaudi2: avoid overriding existing undefined opcode data
Part of the undefined opcode data is updated in
gaudi2_handle_qman_err_generic() and some in
handle_lower_qman_data_on_err().
However, the 'write_enable' flag is checked only in
gaudi2_handle_qman_err_generic(), and information of more than a single
error can be mixed there.

Moreover, handle_lower_qman_data_on_err() is called only for the lower
QMAN, so for an error in the upper QMAN there is only a partial info.

Move all the data update to be done in a single place, protected by the
'write_enable' flag.
As mainly the lower QMAN's info is interesting, avoid saving the partial
info for the upper QMAN.

aa5cea38ce accel/habanalabs: add parent_device sysfs attribute
The device debugfs directory was modified to be named as the
device-name.
This name is the parent device name, i.e. either the PCI address in case
of an ASIC, or the simulator device name in case of a simulator.

This change makes it more difficult for a user to access the debugfs
directory for a specific accel device, because he can't just use the
accel minor id, but he needs to do more device-dependent operations to
get the device name.

To make it easier to get this name, add a 'parent_device' sysfs
attribute that the user can read using the minor id before accessing
debugfs.

Upon a QM error, the address/size from both the CQ and the ARC_CQ are
printed, although the instruction that led to the error was received
from only one of them.

Moreover, in case of a QM undefined opcode, only one of these
address/size sets will be captured based on the value of ARC_CQ_PTR.
However, this value can be non-zero even if currently the CQ is used, in
case the CQ/ARC_CQ are alternately used.

Under the assumption of having a stop-on-error configuration, modify to
use CP_STS.CUR_CQ field to get the relevant CQ for the QM error.

4b0b1fbc77 accel/habanalabs: set hard reset flag if graceful reset is skipped
hl_device_cond_reset() might be called with the hard reset flag unset,
because a compute reset upon device release as part of a graceful reset
is valid.
If the conditions for graceful reset are not met, hl_device_reset() will
be called for an immediate reset. In this case a compute reset is not
valid, so it will be replaced with a hard reset together with a debug
message about it.
This message might be confusing, as it implies that a compute reset was
requested when it shouldn't. To prevent this confusion, set the hard
reset flag in hl_device_cond_reset() if going to an immediate reset.

f64fa33260 accel/habanalabs: add pcie reset prepare/done hooks
When working on a bare-metal system, if FLR will happen the firmware
will handle it and driver will have no knowledge of it, and this will
cause two issues:

1.The driver will be in operational state while it should be in reset.
  This will cause the heartbeat mechanism to keep sending messages to FW
  while pci device is in reset. Eventually heartbeat will fail and
  the device will end up in non-operational state.

2. After FW handles the FLR, and due to the reset it'll go back to
   preboot stage, and driver need to perform hard reset in order to
   load the boot fit binary.

This patch will add reset_prepare hook that will set the device to
be in disabled state, so it'll be not operational, and also
reset_done hook which will be called after the actual FLR handling,
then it will perform hard reset.

5f0a0ebca2 accel/qaic: Expand DRM device lifecycle
Currently the QAIC DRM device registers itself when the MHI QAIC_CONTROL
channel becomes available. This is when the device is able to process
workloads. However, the DRM driver also provides the debugfs interface
bootlog for the device. If the device fails to boot to the QSM (which
brings up the MHI QAIC_CONTROL channel), the bootlog won't be available for
debugging why it failed to boot.

Change when the DRM device registers itself from when QAIC_CONTROL is
available to when the card is first probed on the PCI bus. Additionally,
make the DRM driver persist through reset/error cases so the driver
doesn't have to be reloaded to access the card again. Send
KOBJ_ONLINE/OFFLINE uevents so userspace can know when DRM device is
ready to handle requests.

3f7c063492 accel/ivpu/37xx: Fix hangs related to MMIO reset
There is no need to call MMIO reset using VPU_37XX_BUTTRESS_VPU_IP_RESET
register. IP will be reset by FLR or by entering d0i3. Also IP reset
during power_up is not needed as the VPU is already in reset.

Removing MMIO reset improves stability as it a partial device reset
that is not safe in some corner cases.

47fbee5f27 accel/qaic: Update MAX_ORDER use to be inclusive
MAX_ORDER was redefined so that valid allocations to the page allocator
are in the range of 0..MAX_ORDER, inclusive in the commit
23baf831a3 ("mm, treewide: redefine MAX_ORDER sanely").

We are treating MAX_ORDER as an exclusive value, and thus could be
requesting larger allocations.  Update our use to match the redefinition
of MAX_ORDER.

00a614fc35 accel/ivpu: avoid build failure with CONFIG_PM=n

ivpu_bo_remove_all_bos_from_context() could race with ivpu_bo_free()
when prime buffer was closed after vpu device was closed.

Move the bo_list from context to vdev and use a dedicated lock to
sync it. This list is not modified when BO is added/removed from
a context.

Also rename ivpu_bo_free_vpu_addr() to ivpu_bo_unbind() because this

3b511278b6 accel/qaic: Support for 0 resize slice execution in BO
Add support to partially execute a slice which is resized to zero.
Executing a zero size slice in a BO should mean that there is no DMA
transfers involved but you should still configure doorbell and semaphores.

For example consider a BO of size 18K and it is sliced into 3 6K slices
and user calls partial execute ioctl with resize as 10K.
slice 0 - size is 6k and offset is 0, so resize of 10K will not cut short
          this slice hence we send the entire slice for execution.
slice 1 - size is 6k and offset is 6k, so resize of 10K will cut short this
          slice and only the first 4k should be DMA along with configuring
          doorbell and semaphores.
slice 2 - size is 6k and offset is 12k, so resize of 10k will cut short
          this slice and no DMA transfer would be involved but we should
          would configure doorbell and semaphores.

This change begs to change the behavior of 0 resize. Currently, 0 resize
partial execute ioctl behaves exactly like execute ioctl i.e. no resize.
After this patch all the slice in BO should behave exactly like slice 2 in
above example.

Refactor copy_partial_exec_reqs() to make it more readable and less
complex.

44793c6a5b accel/qaic: Quiet array bounds check on DMA abort message
Current wrapper is right-sized to the message being transferred;
however, this is smaller than the structure defining message wrappers
since the trailing element is a union of message/transfer headers of
various sizes (8 and 32 bytes on 32-bit system where issue was
reported). Using the smaller header with a small message
(wire_trans_dma_xfer is 24 bytes including header) ends up being smaller
than a wrapper with the larger header. There are no accesses outside of
the defined size, however they are possible if the larger union member
is referenced.

Abort messages are outside of hot-path and changing the wrapper struct
would require a larger rewrite, so having the memory allocated to the
message be 8 bytes too big is acceptable.
