drm/v3d: Enable BO mapping

For the indirect CSD CPU job, we will need to access the internal
contents of the BO with the dispatch parameters. Therefore, create
methods to allow the mapping and unmapping of the BO.

Currently, v3d_get_extensions() only parses multisync data and assigns
it to the `struct v3d_submit_ext`. But, to implement the CPU job with
user extensions, we want v3d_get_extensions() to be able to parse CPU

Therefore, allow the function v3d_get_extensions() to use `struct v3d_cpu_job *`
as a parameter. If the `struct v3d_cpu_job *` is assigned to NULL, it means
that the job is a GPU job and CPU job extensions should be rejected.

drm/v3d: Add a CPU job submission

Create a new type of job, a CPU job. A CPU job is a type of job that
performs operations that requires CPU intervention. The overall idea is
to use user extensions to enable different types of CPU job, allowing the
CPU job to perform different operations according to the type of user
extension. The user extension ID identify the type of CPU job that must

Having a CPU job is interesting for synchronization purposes as a CPU
job has a queue like any other V3D job and can be synchoronized by the
multisync extension.

drm/tidss: Use DRM_PLANE_COMMIT_ACTIVE_ONLY

At the moment the driver does not use DRM_PLANE_COMMIT_ACTIVE_ONLY, but
still checks for crtc->state->active in tidss_crtc_atomic_flush(), and
skips the flush if the crtc is not active.

The exact reason why DRM_PLANE_COMMIT_ACTIVE_ONLY is not used has been
lost in history. DRM_PLANE_COMMIT_ACTIVE_ONLY does also affect the plane
updates, and I think the issue was related to multi-display systems and
moving planes between the displays. However, it is possible the issue
was only present on the older DSS hardware, handled by the omapdrm
driver (on which the tidss driver is loosely based).

Reviewing the code related to DRM_PLANE_COMMIT_ACTIVE_ONLY does not show
any issues, and testing on J7 EVM with two displays works fine.

Change the driver to use DRM_PLANE_COMMIT_ACTIVE_ONLY.

drm/tidss: Fix atomic_flush check

tidss_crtc_atomic_flush() checks if the crtc is enabled, and if not,
returns immediately as there's no reason to do any register changes.

However, the code checks for 'crtc->state->enable', which does not
reflect the actual HW state. We should instead look at the
'crtc->state->active' flag.

This causes the tidss_crtc_atomic_flush() to proceed with the flush even
if the active state is false, which then causes us to hit the
WARN_ON(!crtc->state->event) check.

Fix this by checking the active flag, and while at it, fix the related

drm/tidss: IRQ code cleanup

The IRQ setup code is overly complex. All we really need to do is
initialize the related fields in struct tidss_device, and request the
IRQ.

We can drop all the HW accesses, as they are pointless: the driver will
set the IRQs correctly when it needs any of the IRQs, and at probe time
we have done a reset, so we know that all the IRQs are masked by default
in the hardware.

Thus we can combine the tidss_irq_preinstall() and
tidss_irq_postinstall() into the tidss_irq_install() function, drop the
HW accesses, and drop the use of spinlock, as this is done at init time
and there can be no races.

We can also drop the HW access from the tidss_irq_uninstall(), as the
driver will anyway disable and suspend the hardware at remove time.

drm/tidss: Fix dss reset

The probe function calls dispc_softreset() before runtime PM is enabled
and without enabling any of the DSS clocks. This happens to work by
luck, and we need to make sure the DSS HW is active and the fclk is
enabled.

To fix the above, add a new function, dispc_init_hw(), which does:

- pm_runtime_set_active()
- clk_prepare_enable(fclk)
- dispc_softreset().

This ensures that the reset can be successfully accomplished.

Note that we use pm_runtime_set_active(), not the normal
pm_runtime_get(). The reason for this is that at this point we haven't
enabled the runtime PM yet and also we don't want the normal resume
callback to be called: the dispc resume callback does some initial HW
setup, and it expects that the HW was off (no video ports are
streaming). If the bootloader has enabled the DSS and has set up a
boot time splash-screen, the DSS would be enabled and streaming which
might lead to issues with the normal resume callback.

fbdev: Remove default file-I/O implementations

Drop the default implementations for file read, write and mmap
operations. Each fbdev driver must now provide an implementation
and select any necessary helpers. If no implementation has been
set, fbdev returns an errno code to user space. The code is the
same as if the operation had not been set in the file_operations
struct.

This change makes the fbdev helpers for I/O memory optional. Most
systems only use system-memory framebuffers via DRM's fbdev emulation.

* warn once if I/O callbacks are missing (Javier)

fbdev: Warn on incorrect framebuffer access

Test in framebuffer read, write and drawing helpers if FBINFO_VIRTFB
has been set correctly. Framebuffers in I/O memory should only be
accessed with the architecture's respective helpers. Framebuffers
in system memory should be accessed with the regular load and
store operations. Presumably not all drivers get this right, so we
now warn about it.

fbdev: Move default fb_mmap code into helper function

Move the default fb_mmap code for I/O address spaces into the helper
function fb_io_mmap(). The helper can either be called via struct
fb_ops.fb_mmap or as the default if no fb_mmap has been set. Also
set the new helper in __FB_DEFAULT_IOMEM_OPS_MMAP.

In the mid-term, fb_io_mmap() is supposed to become optional. Fbdev
drivers will initialize their struct fb_ops.fb_mmap to the helper
and select a corresponding Kconfig token. The helper can then be made
optional at compile time.

fbdev: Push pgprot_decrypted() into mmap implementations

If a driver sets struct fb_ops.fb_mmap, the fbdev core automatically
calls pgprot_decrypted(). But the default fb_mmap code doesn't handle
pgprot_decrypted().

Move the call to pgprot_decrypted() into each drivers' fb_mmap function.
This only concerns fb_mmap functions for system and DMA memory. For
I/O memory, which is the default case, nothing changes. The fb_mmap
for I/O-memory can later be moved into a helper as well.

DRM's fbdev emulation handles pgprot_decrypted() internally via the
Prime helpers. Fbdev doesn't have to do anything in this case. In
cases where DRM uses deferred I/O, this patch updates fb_mmap correctly.

fbdev/arcfb: Use generator macros for deferred I/O

Implement the driver's fops with the generator macros for deferred
I/O. Only requires per-driver code for the on-scren scanout buffer.
The generated helpers implement reading, writing and drawing on top
of that. Also update the selected Kconfig tokens accordingly.

Actual support for deferred I/O is missing from the driver. So
writing to memory-mapped pages does not automatically update the
scanout buffer.

Fbdev drivers sometimes rely on the callbacks being NULL for a

There is one error path in tilcdc_pdev_remove() that potentially could
yield a non-zero return code. In this case an error message describing
the failure is emitted now instead of

drm/imagination: vm: prevent duplicate drm_gpuvm_bo instances

Use drm_gpuvm_bo_obtain() instead of drm_gpuvm_bo_create(). The latter
should only be used in conjunction with drm_gpuvm_bo_obtain_prealloc().

drm_gpuvm_bo_obtain() re-uses existing instances of a given VM and BO
combination, whereas drm_gpuvm_bo_create() would always create a new
instance of struct drm_gpuvm_bo and hence leave us with duplicates.

drm/ttm: Schedule delayed_delete worker closer

Try to allocate system memory on the NUMA node the device is closest to
and try to run delayed_delete workers on a CPU of this node as well.

To optimize the memory clearing operation when a TTM BO gets freed by
the delayed_delete worker, scheduling it closer to a NUMA node where the
memory was initially allocated helps avoid the cases where the worker
gets randomly scheduled on the CPU cores that are across interconnect
boundaries such as xGMI, PCIe etc.

This change helps USWC GTT allocations on NUMA systems (dGPU) and AMD
APU platforms such as GFXIP9.4.3.

Linux 6.7-rc3

Merge tag 'trace-v6.7-rc2' of git://git./linux/kernel/git/trace/linux-trace

Pull tracing fixes from Steven Rostedt::
 "Eventfs fixes:

   - With the usage of simple_recursive_remove() recommended by Al Viro,
     the code should not be calling "d_invalidate()" itself. Doing so is
     causing crashes. The code was calling d_invalidate() on the race of
     trying to look up a file while the parent was being deleted. This
     was detected, and the added dentry was having d_invalidate() called
     on it, but the deletion of the directory was also calling
     d_invalidate() on that same dentry.

   - A fix to not free the eventfs_inode (ei) until the last dput() was
     called on its ei->dentry made the ei->dentry exist even after it
     was marked for free by setting the ei->is_freed. But code elsewhere
     still was checking if ei->dentry was NULL if ei->is_freed is set
     and would trigger WARN_ON if that was the case. That's no longer
     true and there should not be any warnings when it is true.

   - Use GFP_NOFS for allocations done under eventfs_mutex. The
     eventfs_mutex can be taken on file system reclaim, make sure that
     allocations done under that mutex do not trigger file system
     reclaim.

   - Clean up code by moving the taking of inode_lock out of the helper
     functions and into where they are needed, and not use the parameter
     to know to take it or not. It must always be held but some callers
     of the helper function have it taken when they were called.

   - Warn if the inode_lock is not held in the helper functions.

   - Warn if eventfs_start_creating() is called without a parent. As
     eventfs is underneath tracefs, all files created will have a parent
     (the top one will have a tracefs parent).

   - Add Mathieu Desnoyers as an official reviewer of the tracing subsystem"

Pull parisc architecture fixes from Helge Deller:
 "This patchset fixes and enforces correct section alignments for the
  ex_table, altinstructions, parisc_unwind, jump_table and bug_table
  which are created by inline assembly.

  Due to not being correctly aligned at link & load time they can
  trigger unnecessarily the kernel unaligned exception handler at
  runtime. While at it, I switched the bug table to use relative
  addresses which reduces the size of the table by half on 64-bit.

  We still had the ENOSYM and EREMOTERELEASE errno symbols as left-overs
  from HP-UX, which now trigger build-issues with glibc. We can simply
  remove them.

  Most of the patches are tagged for stable kernel series.

  Summary:

   - Drop HP-UX ENOSYM and EREMOTERELEASE return codes to avoid glibc
     build issues

   - Fix section alignments for ex_table, altinstructions, parisc unwind
