This series is the result of debugging issues root caused to
races between the GuC's destroyed_worker_func being triggered
vs repeating suspend-resume cycles with concurrent delayed
fence signals for engine-freeing.
The reproduction steps require that an app is launched right
before the start of
When suspending, flush the context-guc-id
deregistration worker at the final stages of
intel_gt_suspend_late when we finally call gt_sanitize
that eventually leads down to __uc_sanitize so that
the deregistration worker doesn't fire off later as
we reset the GuC microcontroller.
Signed-off-by:
If we are at the end of suspend or very early in resume
its possible an async fence signal (via rcu_call) is triggered
to free_engines which could lead us to the execution of
the context destruction worker (after a prior worker flush).
Thus, when suspending, insert rcu_barriers at the start
of

Hi,
I have a RPI4B with upstream kernel 6.1 64bit and there is no
/dev/video10 present. I thought if I waited a bit more, it would appear
in the kernel, but that was folly on my part.
Currently, watching a movie is painful since the software decoding is
way too slow and it has very low fps

Disable the autosuspend of runtime PM and use completion to make sure
ps8640_suspend() is called in ps8640_atomic_post_disable().
The ps8640 bridge seems to expect everything to be power cycled at the
disable process, but sometimes ps8640_aux_transfer() holds the runtime
PM reference and prevents

This is mainly a preparatory patch to use memfd_pin_folios() API
for pinning folios. Using folios instead of pages makes sense as
the udmabuf driver needs to handle both shmem and hugetlb cases.
However, the function vmap_udmabuf() still needs a list of pages;
so, we collect all the head pages
Since the memfd pages associated with a udmabuf may be migrated
as part of udmabuf create, we need to verify the data coherency
after successful migration. The new tests added in this patch try
to do just that using 4k sized pages and also 2 MB sized huge
pages for the memfd.
Successful
Using memfd_pin_folios() will ensure that the pages are pinned
correctly using FOLL_PIN. And, this also ensures that we don't
accidentally break features such as memory hotunplug as it would
not allow pinning pages in the movable zone.
Using this new API also simplifies the code as we no longer
For drivers that would like to longterm-pin the folios associated
with a memfd, the memfd_pin_folios() API provides an option to
not only pin the folios via FOLL_PIN but also to check and migrate
them if they reside in movable zone or CMA block. This API
currently works with memfds but it should
A user or admin can configure a VMM (Qemu) Guest's memory to be
backed by hugetlb pages for various reasons. However, a Guest OS
would still allocate (and pin) buffers that are backed by regular
4k sized pages. In order to map these buffers and create dma-bufs
for them on the Host, we first need
Add VM_PFNMAP to vm_flags in the mmap handler to ensure that
the mappings would be managed without using struct page.
And, in the vm_fault handler, use vmf_insert_pfn to share the
page's pfn to userspace instead of directly sharing the page
(via struct page *).

The first two patches were previously reviewed but not yet merged.
These ones need to be merged first as the fourth patch depends on
the changes introduced in them and they also fix bugs seen in
very specific scenarios (running Qemu with hugetlb=on, blob=true
and rebooting guest VM).
