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

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 *".

Mali's CSF firmware triggers the job IRQ whenever there's new firmware
events for processing. While this can be a global event (BIT(31) of the
status register), it's usually an event relating to a command stream
group (the other bit indices).
Panthor throws these events onto a workqueue for processing outside the
IRQ handler. It's therefore useful to have an instrumented tracepoint
that goes beyond the generic IRQ tracepoint for this specific case, as
it can be augmented with additional data, namely the events bit mask.
This can then be used to debug problems relating to GPU jobs events not
being processed quickly enough. The duration_ns field can be used to
work backwards from when the tracepoint fires (at the end of the IRQ
handler) to figure out when the interrupt itself landed, providing not
just information on how long the work queueing took, but also when the
actual interrupt itself arrived.
With this information in hand, the IRQ handler itself being slow can be
excluded as a possible source of problems, and attention can be directed
to the workqueue processing instead.

Mali GPUs have three registers that indicate which parts of the hardware
are powered at any moment. These take the form of bitmaps. In the case
of SHADER_READY for example, a high bit indicates that the shader core
corresponding to that bit index is powered on. These bitmaps aren't
solely contiguous bits, as it's common to have holes in the sequence of
shader core indices, and the actual set of which cores are present is
defined by the "shader present" register.
When the GPU finishes a power state transition, it fires a
GPU_IRQ_POWER_CHANGED_ALL interrupt. After such an interrupt is
received, the _READY registers will contain new interesting data. During
power transitions, the GPU_IRQ_POWER_CHANGED interrupt will fire, and
the registers will likewise contain potentially changed data.
This is not to be confused with the PWR_IRQ_POWER_CHANGED_ALL interrupt,
which is something related to Mali v14+'s power control logic. The
_READY registers and corresponding interrupts are already available in
v9 and onwards.
Expose the data as a tracepoint to userspace. This allows users to debug
various scenarios and gather interesting information, such as: knowing
how much hardware is lit up at any given time, correlating graphics
corruption with a specific powered shader core, measuring when hardware
is allowed to go to a powered off state again, and so on.
The registration/unregistration functions for the tracepoint go through
a wrapper in panthor_hw.c, so that v14+ can implement the same
tracepoint by adding its hardware specific IRQ on/off callbacks to the
panthor_hw.ops member.

The current IRQ helpers do not guarantee mutual exclusion that covers
the entire transaction from accessing the mask member and modifying the
mask register.
This makes it hard, if not impossible, to implement mask modification
helpers that may change one of these outside the normal
suspend/resume/isr code paths.
Add a spinlock to struct panthor_irq that protects both the mask member
and register. Acquire it in all code paths that access these, but drop
it before processing the threaded handler function. Then, add the
aforementioned new helpers: enable_events, and disable_events. They work
by ORing and NANDing the mask bits.
resume is changed to no longer have a mask passed, as pirq->mask is
supposed to be the user-requested mask now, rather than a mirror of the
INT_MASK register contents. Users of the resume helper are adjusted
accordingly, including a rather painful refactor in panthor_mmu.c.
In panthor_mmu.c, the bespoke mask modification is excised, and replaced
with enable_events/disable_events in as_enable/as_disable.

When calling drm_gpuvm_bo_obtain_prealloc() and using immediate mode,
this may result in a call to ops->vm_bo_free(vm_bo) while holding the
GEMs gpuva mutex. This is a problem if ops->vm_bo_free(vm_bo) performs
any operations that are not safe in the fence signalling critical path,
and it turns out that Panthor (the only current user of the method)
calls drm_gem_shmem_unpin() which takes a resv lock internally.
This constitutes both a violation of signalling safety and lock
inversion. To fix this, we modify the method to internally take the GEMs
gpuva mutex so that the mutex can be unlocked before freeing the
preallocated vm_bo.
Note that this modification introduces a requirement that the driver
uses immediate mode to call drm_gpuvm_bo_obtain_prealloc() as it would
otherwise take the wrong lock.

Commit 33729a5fc0 ("iommu/io-pgtable-arm: Remove split on unmap
behavior") did away with the treatment of partial unmaps of huge IOPTEs.
In the case of Panthor, that means an attempt to run a VM_BIND unmap
operation on a memory region whose start address and size aren't 2MiB
aligned, in the event it intersects with a huge page, would lead to ARM
IOMMU management code to fail and a warning being raised.
Presently, and for lack of a better alternative, it's best to have
Panthor handle partial unmaps at the driver level, by unmapping entire
huge pages and remapping the difference between them and the requested
unmap region.
This could change in the future when the VM_BIND uAPI is expanded to
enforce huge page alignment and map/unmap operational constraints that
render this code unnecessary.
When a partial unmap for a huge PTE is attempted, we also need to expand
the locked region to encompass whole huge pages.

Ensure all related groups are evicted and suspended before VM
destruction takes place.
This fixes an issue where panthor_vm_destroy() destroys and unmaps the
heap context while there are still on slot groups using this.
The FW will do a write out to the heap context when a CSG (group) is
suspended, so a premature unmap of the heap context will cause a
GPU page fault.
This page fault is quite harmless, and do not affect the continued
operation of the GPU.
